Repairable LCD and its manufacture

Abstract

A liquid crystal display device has: a first substrate having an insulating surface; a display unit disposed in a central area of the first substrate and including a plurality of pixels disposed in a matrix shape, a plurality of scan lines for activating pixels disposed in a row direction, and a plurality of signal lines each for transferring video data to an activated pixel among pixels disposed in a column direction; a scan line driver circuit formed in a first row direction side area of a peripheral area of the first substrate outside of the display unit, the scan line driver circuit generating a signal for driving the scan lines; a signal line driver circuit formed in a first column direction side area of the peripheral area of the first substrate, the signal line driver circuit generating a signal for driving the signal lines; and a repair circuit formed in a partial area of the peripheral area of the first substrate, the repair circuit having substantially a same structure as a portion of the scan line driver circuit and the signal line driver circuit. A line defect of the display device can be repaired easily.
