Abstract:
1. A liquid crystal display device comprising: an insulating substrate; a gate line arranged in a first direction on the insulating substrate; a data line intersecting and insulated from the gate line and arranged substantially in a second direction; and a thin film transistor connected to the gate line and the data line, the thin film transistor having an active layer and source and drain electrodes each at least partially overlapping the active layer; a protective film disposed on the thin film transistor; and a pixel electrode disposed on the protective film; wherein the drain electrode has a first portion at least partially positioned over the active layer, a second portion extending from the first portion and having a width greater than a width of the first portion, and a third portion extending from the second portion and having a width lesser than the width of the second portion; and wherein the second portion of the drain electrode is connected to the pixel electrode through a contact hole formed therebetween.
