Abstract:
An array substrate for use in reflective liquid crystal display (LCD) device comprising:a substrate having a pixel region; a gate line arranged in a transverse direction on the substrate and defining the pixel region; a data line arranged in a longitudinal direction over the substrate and defining the pixel region with the gate line; a thin film transistor (TFT) comprised of a source electrode, a drain electrode and a gate electrode, wherein the source electrode is extended from the data line, wherein the gate electrode is extended from the gate line, and wherein the drain electrode is spaced apart from the source electrode; an auxiliary drain electrode extended from the drain electrode and formed in the pixel region; a passivation layer having a plurality of concave holes, each concave hole exposing a portion of the auxiliary drain electrode; and a reflective electrode formed on the passivation layer, the reflective electrode contacting the auxiliary drain electrode via a plurality of concave holes.
