Patent ID: 8072403

Claim:
An apparatus comprising: a liquid crystal display comprising sub-pixels each comprising a first display field and a second display field that either both operate in a transmissive mode or both operate in a reflective mode, the first and second display fields of a sub-pixel being driven by a same driving device, the first and second display fields of a sub-pixel having different characteristics that cause liquid crystal layers in the first and second display fields to have different transmittances, wherein the first display field and the second display field of the same sub-pixel have different cell gaps, each sub-pixel comprises a color filter (CF) layer, the CF layer having a first portion covering the first display field and a second portion covering the second display field, the first portion having a first color layer, the second portion having a second color layer and a transparent layer, the transparent layer being between the second color layer and the liquid crystal layer such that the second portion of the CF layer has a thickness greater than that of the first portion of the CF layer, causing the cell gap corresponding to the second portion to be smaller than the cell gap corresponding to the first portion.
