Patent ID: 7944540

Claim:
A method of fabricating a liquid crystal panel for a color filter on thin film transistor (COT) type liquid crystal display (LCD) device, comprising: forming a gate line and a data line on a first substrate having a display area and a non-display area, the non-display area is at a periphery of the display area, the gate line and the data line crossing each other to define a pixel region in the display area; forming a thin film transistor connected to the gate line and the data line; forming a color filter layer over the thin film transistor; forming a black matrix on the color filter layer; forming a pixel electrode contacting the thin film transistor on the color filter layer; forming a common electrode on a second substrate having the display area and the non-display area; forming a first alignment key on the second substrate in the non-display area; forming a first orientation film on the common electrode; forming a sealant between the first and second substrates at a boundary between the display area and the non-display area; attaching the first and second substrates such that the pixel electrode faces the common electrode; and forming a liquid crystal layer between the pixel electrode and the common electrode, wherein the first alignment key is simultaneously formed with the first orientation film.
