Patent ID: 8169586

Claim:
A liquid crystal display panel comprising: a first substrate; a second substrate opposite to the first substrate; and a plurality of first, second and third spacers disposed on the first substrate; wherein one of the first spacers is in contact with the second substrate, a protrusion on the second substrate is at least partially embedded into one of the second spacers so that the one second spacer cannot be moved when an external force is applied to the liquid crystal display panel in parallel or with a certain angle, and one of the third spacers is suspended above the second substrate, wherein the protrusion is disposed on a gate insulation layer of the second substrate, and the protrusion comprises: an amorphous silicon layer formed on the gate insulation layer, a metal layer formed on the amorphous silicon layer, a passivation layer covering the amorphous silicon layer and metal layer, and a pixel electrode layer partially covering the passivation layer, and wherein a first distribution density of the first spacers is larger than that of the second spacers and an additional distribution density of the third spacers is larger than that of the first spacers.
