Abstract:
1. A liquid crystal panel for a color filter on thin film transistor (COT) type liquid crystal display (LCD) device, comprising: first and second substrates facing each other and having a display area and a non-display area, the non-display area is at a periphery of the display area; a gate line and a data line on the first substrate, the gate line and the data line crossing each other to define a pixel region in the display area; a thin film transistor connected to the gate line and the data line; a color filter layer over the thin film transistor; a black matrix directly on the color filter layer; a pixel electrode contacting the thin film transistor on the color filter layer; a patterned spacer in the display area, the patterned spacer including a first sub-layer of an opaque material and a second sub-layer of an organic material on the first sub-layer; a common electrode on the second substrate; a first orientation film on the common electrode; a first alignment key on the second substrate in the non-display area, the first alignment key formed of the same material as the first orientation film; a sealant between the first and second substrates at a boundary between the display area and the non-display area; and a liquid crystal layer between the pixel electrode and the common electrode, wherein the first sub-layer contacts the second sub-layer, and the first sub-layer is closer to the second substrate than the second sub-layer.
