摘要： PROBLEM TO BE SOLVED: To protect a chip-on-glass type active matrix substrate from static electricity and to inspect electric defects on the substrate by arranging each non-linear resistor element between the connection terminal of each gate line or each drain line and an input terminal to a driving IC. SOLUTION: Non-linear resistor elements NL arranged between connection terminals GP, DP and input terminals IDP, IGP and capable of discharging static electricity entered into gate lines G or drain lines D to the direction of a guard ring GR are connected in common by one short-circuit line SLN in each of driving ICs (ICG, ICD) and the line SLN is connected to the guard ring GR on the outside of a cutting line CT. Thereby static electricity entered into the gate lines G or the drain lines D is diffused and absorbed to the guard ring GR through the common short-circuit line SLN prepared in each driving IC, voltage between the gate lines G and the drain lines D is eased and breakdown or the like due to static electricity can be prevented.

摘要： PROBLEM TO BE SOLVED: To make the resistance between terminals on a driving IC and a transparent substrate low and to improve the resistance to errosion of terminals on the substrate by making distance between bumps of a driving IC to be connected to terminals smaller than that between terminals to be connected to the bumps. SOLUTION: In the output terminals DTM from a drain driving IC, the distance L1 between bumps BUMP to be connected to terminals DTM is made smaller than the distance L2 between terminals DTM. For example, L1 is 20μm and L2 is 20μm. Consequently, since the width of the bump BUMP is wider than that of the terminal DTM, even through the mis-registration of the bumps BUMP is generated by the mis-registration of the drain driving IC, the contact areas between the bumps BUMP and the terminals DTM are maintained and the resistances are made low. Moreover, since the distance L2 between terminals DTM is made large, electric errosion of terminals DTM made of a transparent electrically conductive film d1 in which the electric errosion is apt to be generated is suppressed.

摘要： PROBLEM TO BE SOLVED: To suppress charges in the gate-source cross capacitance Cgs and retention capacitance Cadd, even if there are alignment deviations between layers on an active matrix substrate. SOLUTION: A thin-film transistor is formed at the crossing position of a scanning signal line GL and a video signal line DL, while a source electrode SD1 is arranged parallel to the video signal line DL so as to form a channel with a longitudinal direction parallel to the video signal line DL between the video signal line DL and the source electrode SD1. The source electrode is formed as bridging over a semiconductor layer AS which forms the channel. Then an electrode layer is formed on a scanning signal line, and a pixel electrode ITO1 is formed as projecting above the scanning signal line, to form the retention capacitance Cadd using a protective film PAS as a dielectric material.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device preventing unevenness of brightness caused by a source electrode of a thin film transistor by extending the electrode up to the outside of the semiconductor layer forming area, connecting it with a pixel electrode in the extended area, and also forming a pattern widening in the width toward the end along the extending direction on the semiconductor layer. SOLUTION: A source electrode 7A is extending to the side of a pixel area with the width unchanged in parallel with the longitudinal direction of a drain signal line 3, but is widening in the width toward the end on a semiconductor layer 6, and forms an extending part 7B of a comparatively large area. The semiconductor layer 6 is formed so as to somewhat stick out of a gate signal line 2 on the side of a pixel area. In this stuck-out part, the source electrode 7A has a pattern widening toward the end. Thus, when the source electrode 7A is formed by selective etching, it is possible to avoid etching at the intersectional part of the widening part and the side of the semiconductor layer 6.

摘要： PROBLEM TO BE SOLVED: To prevent the generation and infiltration of the static electricity occurring in packaging of elastic material spacers into liquid crystal display elements and to suppress the dielectric breakdown of the liquid crystal display elements by disposing insulating films on the video signal lines existing in the parts where the elastic material spacers come into contact at the single sheet parts at the ends of the liquid crystal display elements. SOLUTION: Protective films (passivation films) PSV1 are formed on the transparent conductive films d1 of the video signal lines existing on the surface of the transparent insulating substrate in the parts where the rubber cushions GC1 (elastic material spacers) come into contact at the single sheet ends at the ends of the liquid crystal display element, i.e., the substrate ends. The protective films PSV1 are formed simultaneously with the protective films PSV 1 in the display parts and are formed of silicon oxide films and silicon nitride films formed by, for example, a plasma CVD apparatus to a film thickness of about 0.6μm. As a result, the direct contact of the rubber cushions GC1 with the transparent conductive films d1 of the video signal lines does not arise any more and, since the insulation resistance by the protective films PSV1 is generated, the dielectric breakdown at the time of packing the rubber cushions is prevented.

摘要： PURPOSE: To attain the compatibility of the lower resistance between driving ICs for driving from a flexible printed board with the improvement in the corrosion resistance of input wirings to the driving ICs. CONSTITUTION: The input wirings Td to the driving ICs connected with the output terminals of the flexible printed board FPC packaged at the end of the surface of a transparent insulating substrate SUB1 consist, successively from the lower layers, of a first conductive film g1, a transparent conductive film d1 and second and third conductive films d2, d3. The surfaces of these second and third conductive films d2, d3 are coated with protective films PSV1. The second and third conductive films d2, d3 and the protective films PSV1 are removed in the parts to be connected with the output terminals of the flexible printed board FPC and are formed to a comb shape. These films are removed as well in bump junctures BP to be connected with the bumps of the driving ICs, by which the transparent conductive film d1 is exposed. Further, the first conductive film g1 and the third conductive film d3 are connected via through-holes TH1, TH2.
