Patent ID: 7436461

Claim:
A liquid crystal display device comprising: a transparent substrate, at least one thin film transistor having a gate electrode, a gate insulating layer over the gate electrode, a semiconductor layer, a source electrode and a drain electrode, a passivation layer located on the at least one thin film transistor, a pixel electrode connected to the drain electrode of the at least one thin film transistor, a gate line connected to the gate electrode of the at least one thin film transistor, a data line connected to the source electrode of the at least one thin film transistor; a first trench-shaped hole formed in the passivation layer and the gate insulating layer along a first side of at least one of the data line and the gate line between the pixel electrode and the at least one of the data line and the gate line to expose the transparent substrate, the pixel electrode in the first trench exposing the transparent substrate; and a second trench-shaped hole formed in the passivation layer and the gate insulating layer along a second, opposite side of the at least one of the data line and the gate line, wherein the first and second trench-shaped holes expose the substrate.
