摘要： A liquid crystal display device includes pixels, each of which includes a first transistor and a second transistor. The size of the first transistor is larger than the size of the second transistor. In addition, channel widths and gate widths for the first transistor are larger than those of the second transistor. Also, the first transistor is located to be closer to a drain signal line provided for the pixel than the second transistor. In normal operation, the first transistor is coupled to the drain signal line and the second transistor is floating. However, if an abnormality occurs in the first transistor, it is cut off from the drain signal line and the second transistor is connected to the drain signal line by a repair line.

摘要： A normal transistor CTFT connected to a data signal line DL and a pixel electrode PX and a spare transistor FTFT in a floating state are formed on a gate line GL. When an operational abnormality occurs in the normal transistor CTFT, the normal transistor CTFT is cut off from the data signal line DL and is cut off from the pixel electrode PX connected via a through hole TH by cutting lines CL. Thereafter, the spare transistor FTFT is connected to the data signal line DL and the pixel electrode PX by repair lines RL.

摘要： An etching resist including first and second portions, the first portion being thicker than the second portion, is formed on a metallic layer. Through the etching resist, a semiconductor layer and the metallic layer are patterned by etching so as to form a wiring from the metallic layer and leave the semiconductor layer under the wiring. An electrical test is conducted on the wiring. The second portion is removed while the first portion is left unremoved. Selective etching is performed through the first portion so as to leave the semiconductor layer unetched to pattern the wiring to be divided into drain and source electrodes. A substrate is cut. In patterning the wiring, the wiring is etched to be cut at a position closer to a cutting line of the substrate with respect to the drain and source electrodes, while leaving the semiconductor layer unetched.

摘要： In a substrate of a liquid crystal display device which forms a bus line which three-dimensionally intersects scanning signal lines, video signal lines and an insulation layer thereon, the present invention facilitates repairs of short-circuiting between the respective signal lines and the bus line. A liquid crystal display device includes a liquid crystal panel which is constituted of a pair of substrates with liquid crystal sandwiched therebetween. Out of the pair of substrates, one substrate includes a bus line which is arranged outside a display region and is electrically connected to a first conductive layer arranged inside the display region, and a plurality of signal lines which three-dimensionally intersect the bus line by way of an insulation layer. The bus line includes opening portions outside intersecting regions where the bus line is overlapped to the signal lines as viewed in a plan view. The opening portions are arranged on both sides of each intersecting region.

摘要： The present invention reduces a connection failure between two conductive layers which are connected with each other via a through hole in a display device and reduces a defect of an orientation film formed on a TFT substrate side in a liquid crystal display device. A display device includes a display panel in which a first conductive layer formed on a surface of a substrate, and a second conductive layer which is formed over the first conductive layer as viewed from a surface of the substrate by way of a thin film layer formed of one insulation film or two or more stacked thin films including one insulation film are electrically connected with each other in an opening portion formed in the thin film layer. Out of opening ends of the opening portion of the thin film layer, an outer periphery of the opening end remote from the surface of the substrate changes a distance from the surface of the substrate one time or more during one turn of the outer periphery.
