Abstract
One embodiment of the present invention provides a transflective display in which a border area adjacent to an active area has a reflectivity that is substantially the same as the active area when the display is turned off. This display includes a polarizer layer, a color filter glass (CFG) layer, a liquid crystal layer, and a reflector layer. The CFG layer contains color filters in the active area, while the border area of the CFG layer is designed to have a reflectivity that is substantially the same as the active area when the display is turned off.
