Abstract: A liquid crystal display device includes a TFT substrate and a counter substrate with liquid crystal sandwiched therebetween. The TFT substrate has scanning lines 10 extending in a first direction and arrayed in a second direction and video signal lines 20 extending in the second direction and arrayed in the first direction. The TFT substrate has a display area 500 in which TFT pixels are arrayed in a matrix pattern, and a frame area 600 surrounding the display area. In the frame area 600, common bus wires 521 are formed in the same layer and with the same material as the video signal lines 20 and are impressed with a common voltage. Dummy TFTs are formed in a layer under the common bus wires 521. The scanning lines 10, extending over the frame area 600, are divided outside the display area and are interconnected by bridging wires 170.

Abstract: To improve the reliability of a display device.The display device includes a display portion, an input unit, and a lead-out wiring portion which connects the display portion and the input unit to each other. In addition, the input unit includes a first terminal group in which a plurality of first terminals are arranged. In addition, the lead-out wiring portion includes a plurality of first lead-out wirings connected to the plurality of first terminals. In addition, a first end-portion wiring, which is formed in an end portion of an array, among the plurality of first lead-out wirings, includes a first main line which extends along an extending direction of a neighboring first lead-out wiring, a first bypass line which extends along the first main line, and a first branch portion and a second branch portion which connect the first main line and the first bypass line to each other.

Abstract: Conductive rubbing sludge generated by rubbing attaches to side portions of chip-on-glass (COG) terminals and terminal wiring lines and possibly causes short-circuiting (leakage) between adjacent terminal wiring lines via particles included in an anisotropic conductive film (ACF) which connects bumps of a semiconductor chip such as a driver IC to COG terminals. In the liquid crystal display device, each terminal wiring line connected to a COG terminal has a projecting part designed to generate an area not subjected to rubbing.
