Patent ID: 7474372

Claim:
A liquid crystal display device having liquid crystal cells arranged in a matrix type, comprising: a gate line for receiving a scanning signal; a data line for receiving a data signal; a pixel electrode provided at an intersection of the gate line and the data line to drive a liquid crystal cell; a thin film transistor for responding to the scanning signal to switch the data signal into the pixel electrode; a common line laterally adjacent to the pixel electrode along a direction of one of the gate and data lines; and an alignment film formed on at least a portion of the gate line, the data line and the pixel electrode to determine a primary alignment direction of a liquid crystal, wherein the pixel electrode and the common electrode are disposed directly on an insulating layer that serves as the gate insulating layer of the thin film transistor, and wherein the alignment film directly contacts upper and side surfaces of the common line, upper and side surfaces of the pixel electrode, and upper surfaces of the source and drain electrodes of the thin film transistor.
