Patent ID: 8325312

Claim:
A liquid crystal display device comprising: a first substrate and a second substrate facing each other, wherein a plurality of subpixels, each including a pixel region and a non-pixel region adjacent to the pixel region, are defined in the form of a matrix on the first substrate and the second substrate; a plurality of gate lines and a plurality of data lines formed in respective non-pixel regions on the first substrate such that the gate lines and the data lines intersect each other, to define the pixel regions; a plurality of thin film transistors each formed at an intersection between an associated one of the gate lines and an associated one of the data lines; a black matrix layer formed on the second substrate in portions corresponding to the non-pixel regions; a plurality of first spacers formed on the black matrix layer between the first and second substrates, the first spacers comprising a plurality of first balls with a first diameter and a first solid to aggregate the first balls, wherein the first diameter of the first ball is 2.0 to 5.0 μm; a plurality of second spacers formed on the black matrix layer between the first and second substrates, the second spacers comprising a plurality of second balls with a second diameter smaller than the first diameter and a second solid to aggregate the second balls, wherein the difference between the first diameter and the second diameter is 0.2 to 0.6 μm; and a liquid crystal layer filled between the first substrate and the second substrate, wherein the first spacers and the second spacers are arranged on the different regions of the black matrix layer, wherein, the first spacers are formed by ink-jetting a first spacer material onto the predetermined portions on the black matrix layer, followed by curing, and the second spacers are formed by ink-jetting a second spacer material onto the predetermined portions on the black matrix layer, followed by curing; wherein the first spacer material comprise a liquid thermosetting binder, a solvent, a first balls; when the total weight of the liquid thermosetting binder and the solvent is equal to 100 wt %, wherein the weight of the liquid thermosetting binder is 1 wt % to 20 wt %, and the weight of the solvent is 80 wt % to 99 wt %; and, the weight of the first balls is 0.1 wt % to 3 wt % with respect to the total weight of the liquid thermosetting binder and the solvent; and when the second spacer material comprise a liquid thermosetting binder, a solvent, a second ball, if the total weight of the liquid thermosetting binder and the solvent is equal to 100 wt %, wherein the weight of the liquid thermosetting binder is 1 wt % to 20 wt %, and the weight of the solvent is 80 wt % to 99 wt %; and, the weight of the second balls is 0.1 wt % to 3 wt % with respect to the total weight of the liquid thermosetting binder and the solvent; and wherein the first balls and the second balls includes at least of divinylbenzene polymer.
