Abstract:
1. An array substrate for a liquid crystal display device, comprising: first and second lines on a substrate and spaced apart from each other, the first and second lines formed of a first metallic material; a gate electrode connected to the first line; a gate insulating layer on the first and second lines and the gate electrode and including a groove, the groove exposing the substrate and positioned between the first and second lines; a semiconductor layer on the gate insulating layer and corresponding to the gate electrode; a data line crossing the first and second lines and on the gate insulating layer; a source electrode on the semiconductor layer and connected to the data line; a drain electrode on the semiconductor layer and spaced apart from the source electrode; a passivation layer on the data line, the source electrode and the drain electrode and including an opening, the opening exposing a portion of the gate insulating layer and an end of the drain electrode; and a pixel electrode positioned on the gate insulating layer and in the opening, the pixel electrode contacting the end of the drain electrode, wherein the passivation layer contacts the substrate at the groove.
