Patent ID: 7567324

Claim:
A liquid crystal display device comprising: a liquid crystal display panel having an array substrate and a color filter substrate; a plurality of gate lines and a plurality of data lines arranged vertically and horizontally on the array substrate and defining a plurality of pixel regions; a first thin film transistor formed on the array substrate and having a first gate electrode, a first source electrode, a first drain electrode and a first active layer for forming a first conductive channel between the first source electrode and the first drain electrode; and a first compensation pattern formed on both sides of one of the first source electrode and the first drain electrode of the first thin film transistor in a first pixel region at a first position of the plurality of pixel regions such that the first compensation pattern is partially overlapped by the first gate electrode, wherein the first compensation pattern is made of the same conductive material as one of the first source electrode and the first drain electrode and wherein the first compensation pattern is located at both sides of one of the first source electrode and the first drain electrode but not in the first conductive channel.
