Abstract:
A reflective type fringe field switching mode liquid crystal display (â€œa reflective FFS-LCDâ€ ) comprising:a liquid crystal layer having a plurality of the liquid crystal molecules and having the thickness of a cell gap; a first substrate disposed on one side of the liquid crystal layer and a counter electrode having a counter electrode width and a pixel electrode having a pixel electrode width formed on the first substrate, wherein the counter electrode and the pixel electrode are separated by a predetermined distance that is less than the cell gap thickness to generate a fringe field to drive the liquid crystal molecules; a second substrate disposed on the other side of the liquid crystal layer; a first homogeneous alignment layer interposed between the liquid crystal layer and the first substrate and having a rubbing axis in a selected direction; a second homogeneous alignment layer interposed between the liquid crystal layer and the second substrate, and having a rubbing axis in a selected direction; a polarizer disposed on an outer surface of one of the first substrate and the second substrate, and having a selected polarizing axis; and a reflective plate disposed on an outer surface of the other of the first substrate and the second substrate, wherein retardation in the liquid crystal layer is caused to occur in the absence of a quarter wave plate for retarding incident light by &lgr;/4 when the liquid crystal molecules in the liquid crystal layer are driven by the fringe field and wherein &lgr; is about 570 nm.
