Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display preventing movement of a spacer maintaining a cell gap between substrates by external pressure and light leakage due to positional change of the spacer by forming the spacer in a polyhedron shape having a surface treatment layer to reinforce a contact area and adhesive force to the substrates, and to provide its manufacturing method. SOLUTION: The liquid crystal display includes a first substrate comprising gate lines, data lines substantially intersecting the gate lines and a first alignment layer, a second substrate stuck to the first substrate opposite to each other and comprising a color filter layer and a second alignment layer and the polyhedric spacer maintaining the cell gap between the first and the second substrates. The spacer includes the surface treatment layer which is bonded to at least either one of the first and the second alignment layers to reinforce the adhesive force. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide an array substrate for liquid crystal display device and its manufacture method in which a mask process is simplified by applying a top gate type thin film transistor to an array part and the yield is improved by shortening the process time. SOLUTION: A color filter 130 is formed in the upper part of the top gate type thin film transistor array part. Therein, when the array part of the top gate type thin film transistor including the color filter 130 is formed, a source electrode 106, a drain electrode 108 and an impurity amorphous silicon layer are patterned at the same time, and a gate electrode 124, an active layer 120 and a gate insulating film are patterned and formed at the same time. Such a array substrate for liquid crystal display device of COT (color filter on thin film transister) structure has an advantage capable of simplifying processes in the manufacture.

Abstract: A liquid crystal display (LCD) device and its fabrication method are disclosed. Specifically, a fabrication method in which polyhedral spacers are implemented on a substrate through an ink jet method are used for an LCD device. The spacers have the polyhedral shape to increase their contact area with two substrates, and include a surface processed layer for strengthening a bonding force in its bonding with an alignment film formed on the two substrates. The spacers have a polyhedral shape for maintaining the cell gap between the substrates.
