摘要： PROBLEM TO BE SOLVED: To provide the manufacture of a large-area liquid crystal display device which has inconspicuous joints and excellent display quality. SOLUTION: A conductor layer or dielectric layer formed on the glass substrate of the liquid crystal display device is divided into areas (A, B, D, and E), which are exposed and patterned, area by area. The border lines of the divided areas are formed zigzag and engaged with the border lines of other divided areas. At a cross part where a horizontal border line (a) dividing the areas horizontally and a vertical border line (b) dividing the areas vertically cross each other at right angles, the zigzag border line of the divided area has a pattern extending into the diagonally opposite divided area.

摘要： PROBLEM TO BE SOLVED: To make it possible to provide a uniform image over a whole display area by arranging a former scanning line, a pixel electrode incapable of forming auxiliary capacity and conductive wiring forming the auxiliary capacity and applying a signal having a compensation pulse. SOLUTION: A drive waveform Vg0 of a scanning signal applied to a dummy scanning line is only the compensation pulse 14 (c). Further, the drive waveform of the scanning signal applied to the scanning line of the first row or after is provided with a scanning pulse 21 turning the TFT on and the compensation pulse 14 (d, e). Then, the potential waveform of the pixel electrode of the first row m-th column forming the auxiliary capacity with the dummy scanning line through an insulation film becomes the potential waveform Vp1 shown by a solid line (a). On the other hand, the potential waveform of the pixel electrode connected to the scanning line of the second row or after, e.g. the potential waveform of the pixel electrode of (m+1)-th row becomes the potential waveform Vp2 shown by the solid line (b). In such a manner, by applying the signal having the compensation pulse to not only the scanning line but also the dummy scanning line, flickers in a picture are prevented.

摘要： PROBLEM TO BE SOLVED: To prevent signal lines from disconnection at intersections of signal lines and main scanning lines and to achieve a high yield. SOLUTION: At ends of scanning lines 111 at the intersection of signal lines 103 (103a, 103b) and the scanning lines 111, a line width of Al of an upper layer 103b, which is a layer conductive layer of a signal line, is made wider than that of ITO(indium tin oxide) layer of an lower layer 103a so as to cover the ITO of the lower layer 103a. Thus, even if the ITO is disconnected stepwise, it is possible to eliminate the disconnection failure of the signal line 103 by preventing the etching solution of A1 from soaking.

摘要： PROBLEM TO BE SOLVED: To prevent an orientation film from being damaged due to movement of spacers and to remove defect display by arranging an insulating film patterned so as to have plural apertures in one pixel electrode area on an array substrate or a counter substrate. SOLUTION: A pixel electrode 40 is arranged to be connected to a switching element through a source electrode 41. A grating-like insulating film 60 consisting of silicon nitride and patterned to have plural apertuers 61 dividing a pixel electrode area into plural parts is formed to cover a signal line 20, a scanning line 30 and a switching element. An orientation film is arranged to cover the whole elements. The insulting film 60 is formed to have plural apertures 61 in one pixel electrode area. Since reggedness is formed on the electrode 40, the movement of granular spacers in a display area can be controlled by the ruggedness.
