Abstract:
1. An array substrate of a LCD, wherein a liquid crystal layer is disposed thereon, the array substrate comprising: a substrate, comprising a first sub-pixel region and a second sub-pixel region; a lower electrode disposed on the substrate, wherein a portion of the lower electrode is disposed in the first sub-pixel region, and the other portion of the lower electrode is disposed in the second sub-pixel region; a dielectric layer disposed on the lower electrode and the substrate; an upper electrode disposed on the dielectric layer above the lower electrode; a passivation layer disposed on the upper electrode and the dielectric layer, wherein the passivation layer has an opening to expose the upper surface of the upper electrode, and the thickness of the passivation layer in the first sub-pixel region is different from the thickness of the passivation layer in the second sub-pixel region so that the thickness of the liquid crystal layer disposed above the first sub-pixel region is different from the thickness of the liquid crystal layer disposed above the second sub-pixel region; and a first sub-pixel and a second sub-pixel electrode respectively disposed on the passivation layer and the upper electrode in the first sub-pixel region and the second sub-pixel region, wherein the first sub-pixel and the second sub-pixel electrodes are electrically connected to the upper electrode.
