Abstract

In an embodiment, a multi-mode LCD comprises pixels, each comprising sub-pixels, each sub-pixel comprising a first polarizing layer; a second polarizing layer; a first substrate layer and an oppositely oriented second substrate layer, the first and second substrate layers are between the first and second polarizing layers; a liquid crystal material between the first and second substrate layers; a first reflective layer that is adjacent to the first substrate layer and comprises at least one opening that forms a transmissive part of the sub-pixel and wherein a remainder of the first reflective layer that forms a reflective part of the sub-pixel; a first filter of a first color opposite to and covering the transmissive part with an area larger than that of the transmissive part; a second filter of a second color opposite to and partially covering the reflective part, wherein the second color is different from the first color.
