Patent ID: 7428024

Claim:
An array substrate for an active matrix type liquid crystal display (LCD) device, comprising: a substrate; a gate line on said substrate, wherein said gate line includes a gate pad; a first insulating layer on said gate line and said substrate; a semiconductor layer on said first insulating layer and over a portion of said gate line; a data line over said first insulating layer and that crosses said gate line, said data line including a protruding portion that projects in a direction of said semiconductor layer and that forms a source electrode, wherein an end portion of the semiconductor layer under the data line is substantially a same width as an end portion of the data line, wherein said data line further includes a data pad; a drain electrode spaced apart from said source electrode and extending into a rectangular region partially defined by said gate and data lines; a passivation layer on said drain electrode, said passivation layer having a drain contact hole that exposes said drain electrode; and a pixel electrode formed over the passivation layer, said pixel electrode electrically connecting to said drain electrode via said drain contact hole, wherein said pixel electrode extends over a portion of said gate line so as to form a storage capacitor comprised of a capacitor electrode extending from the pixel electrode, said gate line, and said first insulating layer therebetween, wherein said storage capacitor further includes a short-preventing part disposed between said pixel electrode and said gate line, wherein the short-preventing part has a stepped portion that overlaps a stepped end portion of the gate line, and wherein said short-preventing part includes said semiconductor layer and said passivation layer.
