Patent ID: 8345212

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate facing the first substrate; a ball spacer between the first substrate and the second substrate; a gate line on the first substrate, the gate line having a gate electrode; a common line parallel to the gate line and having a common electrode, an insulating layer insulating the gate line; a channel pattern on the insulating layer, the channel pattern corresponding to the gate electrode; a data line having a source electrode on the channel pattern; a drain electrode on the channel pattern, the drain electrode being separated from the source electrode; a passivation layer covering the channel pattern, the data line and the drain electrode; a pixel electrode electrically connected with the drain electrode and disposed on the passivation layer; a lower barrier disposed on the passivation layer; and an upper barrier disposed on the second substrate and facing the lower barrier; wherein a first side wall of the lower barrier protrudes from the passivation layer along the gate line, wherein a second side wall of the lower barrier protrudes from the passivation layer along the common line and faces the first side wall so that a movement of the ball spacer is restricted by the first and second side walls, wherein the ball spacer is disposed between the lower barrier on the gate line and the lower barrier on the common line, wherein a portion of the ball spacer is disposed on the gate line and another portion of the ball spacer is disposed on the common lines, and wherein the first and second side walls are made of a different material from the passivation layer and the pixel electrode.
