Color filter on thin film transistor type liquid crystal display device and method of fabricating the same with an alignment key formed with the orientation layer

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 filer 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 light-shielding pattern at a boundary between the display area and the non-display area;
• 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 sealant between the first and second substrates at the boundary between the display area and the non-display area;
• a liquid crystal layer between the pixel electrode and the common electrode;
• and
• a top case and a bottom case enclosing the first and second substrates therein,
• wherein the light-shielding pattern corresponds to end portions of the top case,
• 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.
