Patent ID: 8796691

Claim:
A system for displaying images, comprising: a thin film transistor substrate, comprising: a substrate having a display area and a pad area; a conductive line disposed on the substrate in the display area comprising a lower metal line, an upper metal line and a middle metal line disposed directly between the upper metal line and the lower metal line, wherein a width of the middle metal line is narrower than that of the upper metal line and that of the lower metal line; a bonding pad disposed in the pad area, wherein the bonding pad comprises a lower metal bonding pad, a middle metal bonding pad and an upper metal bonding pad, wherein a width the middle metal bonding pad is narrower than that of the upper metal bonding pad and the lower bonding pad; a photo-sensitive material on the sidewalls of the middle metal bonding pad and between the upper metal pad and lower metal pad; and a conductive protection layer covering the upper metal pad.
