ABSTRACT:
The present invention of reflective liquid crystal display device include in: substrate having a surface; a pixel electrode on the surface; a first liquid crystal layer provided on the substrate; a second liquid crystal layer provided on the first liquid crystal layer; a counter electrode formed on the second liquid crystal layer; and a separating member provided between the first liquid crystal layer and the second liquid crystal layer. The first and second liquid crystal layers constituted by liquid crystal material having Bragg reflection(selective reflection in the same twist direction. The separating layer constituted optical compensator.
