Patent ID: 7349046

Claim:
A pixel device of a transfiective-type liquid crystal panel comprising: an upper panel; a lower panel assembled beneath said upper panel; a reflector formed on an upper surface of the lower panel to defined the upper surface having a reflective region and a transmission region; a liquid crystal layer interposed between said upper panel and said lower panel; and a liquid crystal film, which is set with an opposing spiral direction with respect to that of said liquid crystal layer, formed on said liquid crystal layer to compensate retardation of said liquid crystal layer; wherein an ambient linear polarized light in the reflective region passing through the liquid crystal film and the liquid crystal layer being reflected by the reflector to result a first linear polarized light leaving the liquid crystal film with a polarizing direction substantially perpendicular to that of the ambient linear polarized light in the pixel device with a substantially non-operation voltage and a backlight linear polarized light in the transmission region passing through the liquid crystal layer and the liquid crystal film being transformed into a third linear polarized light leaving the liquid crystal film with a polarizing direction substantially perpendicular to that of the backlight linear polarized light in the pixel device with a substantially non-operation voltage.
