Patent ID: 8599336

Claim:
A liquid crystal display device, comprising: first and second substrates facing each other, wherein a pixel region is defined on the first and second substrates; first and second grooves formed on an inner surface of the first substrate; a gate line formed in the first groove along a direction; a common line formed in the second groove and parallel to the gate line; a data line crossing the gate line to define the pixel region; a thin film transistor connected to the gate line and the data line; a light-shielding pattern of a black inorganic material and around the gate line, the data line and the common line; third grooves formed on an inner surface of the first substrate and in the pixel region, the third grooves extending from the second groove; outer common electrodes in the third grooves and extending from the common line; a passivation layer over the gate line and the data line; and pixel electrodes directly on and contacting the inner surface of the first substrate in the pixel region and electrically connected to a drain electrode of the thin film transistor.
