Liquid crystal display device

1. A liquid crystal display device, comprising:

an array substrate that includes gate and data lines crossing each other to define a pixel region, and a thin film transistor and a pixel electrode in the pixel region;

an opposing substrate that faces the array substrate and includes a black matrix corresponding to a boundary of the pixel region, and a color filter layer filling a region surrounded by the black matrix;

a patterned spacer on the black matrix and having a diamond shape in plane; and

a liquid crystal layer between the array substrate and the opposing substrate,

wherein the patterned spacer corresponds to a crossing portion of the gate and data lines, and vertices of the diamond shape of the patterned spacer are on the gate and data lines outside the crossing portion of the gate and data lines.

2. The device according to claim 1 , wherein the patterned spacer has an inward-curved diamond shape in plane, four sides of which each have an inward curvature.

3. The device according to claim 1 wherein a distance between opposite vertices of the diamond shape is about 10 μm to 15 μm, a distance between opposite sides of the diamond shape is about 6 μm to about 11 μm, and the distance between the opposite vertices is greater than the distance between the opposite sides.

4. The device according to claim 1 , wherein a distance between a side of the diamond shape and a corresponding side surface of the black matrix is about 5 μm or more.

5. The device according to claim 1 , wherein the opposing substrate further includes a common electrode on the color filter layer, and wherein the patterned spacer is on the common electrode.

6. The device according to claim 1 , wherein the array substrate further includes a common line that is parallel with and formed at the same layer as the gate line, and a common electrode that alternates with the pixel electrode in the pixel region and is connected to the common line.
