Abstract
A color liquid crystal display device including a transparent first substrate having an inner surface and at least one transparent electrode formed thereon, and an insulating second substrate having an inner surface arranged to oppose the inner surface of the first substrate and at least one electrode formed on the inner surface of the second substrate. A liquid crystal layer is sandwiched between the inner surfaces of the first and second substrates and has a predetermined initial aligned state. A polarizing member is arranged on a first substrate side of the liquid crystal layer, and at least one retardation plate is provided for coloring light which emerges from the liquid crystal display. The retardation plate is arranged between the liquid crystal layer and the polarizing member such that an optical axis of the retardation plate with respect to a transmission axis of the polarizing member is not parallel to or perpendicular to the transmission axis. A reflecting member is arranged on a liquid crystal layer side of the second substrate.
