Abstract:
1. An array substrate for a liquid crystal display device, comprising: a gate line and a first storage electrode on a substrate, wherein the first storage electrode occupies a portion of the gate line; a gate insulating layer on the gate line and the first storage electrode; a data line over the gate insulating layer, the data line crossing the gate line to define a pixel region; a thin film transistor having a gate electrode connected to the gate line, a semiconductor layer over the gate electrode, a source electrode connected to the data line, and a drain electrode spaced apart from the source electrode; a passivation layer on the data line, wherein a first thickness of the passivation layer plus the gate insulating layer over the first storage electrode is thinner than a second thickness of the passivation layer plus the gate insulating layer over the gate electrode; and a pixel electrode and a second storage electrode on the passivation layer, the second storage electrode extended from the pixel electrode and overlapped with the first storage electrode.
