A display device displays images with reduced glare from external incident
light. The device includes a back light located on a bottom surface of
the display device to provide internal light. Moreover, the device
includes an internal circular X-polarizer located external to the back
light to circularly polarize internal light. In addition, the device
includes a mirror to reflect external incident light. Furthermore, the
device includes a liquid crystal display located external to the mirror
and the internal circular X-polarizer to display images. The device also
includes an external circular X-polarizer located external to the liquid
crystal display to circularly polarize external incident light, and
absorb reflected external incident light and polarized internal light.
