Abstract:
1. A liquid crystal display device comprising: a liquid crystal display panel having pixels disposed on intersections between a plurality of scan lines and signal lines; a flexible wiring substrate having mounted thereon a drive IC electrically connected to the liquid crystal display panel, the drive IC being mounted on the flexible wiring substrate by means of chip-on-film technology and supplying video signals to one of N number of the signal lines allocated to the drive IC, wherein N is an integer of two or more; an analog switch circuit switch-connected to the one of the N number of the signal lines; and control lines formed across a region in which the drive IC has been mounted on the flexible wiring substrate, the control lines being insulated from the drive IC and drawn from a center of the flexible wiring substrate onto the liquid crystal display panel for supplying control signal for driving the analog switch circuit, wherein the control lines comprise two lines, the two lines:
