Liquid crystal display device and fabrication method thereof
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.
1. A liquid crystal display device comprising:
a first substrate having gate lines and data lines, the data lines substantially crossing the gate lines, wherein the first substrate includes a first alignment film;
a second substrate coupled with the first substrate, the second substrate including a color filter layer and a second alignment film;
a plurality of independent spacers formed between the first alignment film and the second alignment film for maintaining a cell gap between the first substrate and the second substrate, wherein the independent spacer is formed a plurality of unit solid polyhedral spacers; and
a surface processed layer on the surface of the unit solid polyhedral spacers to increase adhesive strength with the first and second alignment films, wherein the surface processed layer has a redundancy coupler which remains after a chain of the dual bond is released.
2. The device of claim 1 , wherein the plurality of independent spacers are on the crossings of the gate lines and the data lines.
3. The device of claim 1 , wherein the unit solid polyhedral spacers have a cubic shape.
