ABSTRACT:
A FFS semi-transmissive LCD comprises a first substrate and pixel matrix. The pixel matrix is disposed on the first substrate and comprises a plurality of pixel units. Each pixel unit comprises a counter electrode, pixel electrode layer, reflection layer and liquid-crystal disposition layer. The counter electrode is disposed on the first substrate. The pixel electrode layer is disposed above the counter electrode. The reflection layer is disposed between the first substrate and pixel electrode layer. The reflection layer is smaller than the counter electrode in area. The liquid-crystal disposition layer is disposed on the pixel electrode layer and comprises a transparent material layer. The transparent material layer is smaller than the liquid-crystal disposition layer in thickness and has substantially the same shape and area as the reflection layer, and the transparent material layer and the reflection layer are face-to-face disposed at two opposite sides of the pixel electrode layer.
