Abstract: A display device in which ambient light reflections, for example, from IPS or FFS type displays are reduced by a circular polariser (e.g., linear polariser combined with external quarter waveplate) to make the light circular polarized, as it traverses the multiple reflective layers between the polariser and LC layer, and then an internal quarter waveplate converts the light back to linear polarisation before it enters the LC, so the display can operate as normal, while the circular polariser absorbs unwanted reflections of ambient light from within the display.

Abstract: A liquid crystal device (LCD) is configured for minimizing unwanted internal ambient light reflections. The LCD includes a plurality of layers, the layers comprising from a viewing side: a first linear polariser; an external retarder that is made of a cyclic olefin polymer (COP) material or a cyclic olefin copolymer (COC) material; a colour filter substrate; a colour filter layer; an internal reactive mesogen (RM) retarder alignment layer; an internal reactive mesogen (RM) retarder; a liquid crystal (LC) layer; and a second linear polarizer. The external retarder and the internal RM retarder are configured such that the optical properties (for example light polarization control function) of the external retarder and the internal retarder are matched to negate each other for light passing through the external retarder and the internal RM retarder. The LCD simultaneously maintains high image quality in both high and low ambient lighting conditions.

Abstract: The present invention provides a mirror display that can suppress warp of a half mirror plate with a reflective polarizer under heat to prevent distortion of a reflected image in a mirror mode. The mirror display of the present invention includes a half mirror plate that includes a first reflective polarizer and a first base material, a display device, and a warp-suppressing member that suppresses shrinking of the first reflective polarizer under heat. The first reflective polarizer and the first base material are integrated, and the display device is disposed on the back surface side of the half mirror plate.
