Patent ID: 7489369

Claim:
An array substrate for a liquid crystal display device, comprising: a gate line and a gate pad on a substrate; a data line and a data pad on the substrate, the data line crossing the gate line to define a pixel region; a thin film transistor at a crossing of the gate and data lines and including a gate electrode, an active layer, a source electrode and a drain electrode; a passivation layer provided on an entire surface of the substrate including the thin film transistor, wherein the passivation layer is etched to expose the substrate in the pixel region, a part of the drain electrode, the gate pad, and the data pad, and wherein the passivation layer has reversely tapered sides; and a pixel electrode, a gate pad terminal and a data pad terminal on the substrate including the passivation layer, the pixel electrode directly contacting the exposed part of the drain electrode, the gate pad terminal contacting the exposed gate pad, and the data pad terminal contacting the data pad.
