  • Display device and electronic equipment having the same comprising a region for reflecting a polarized light and a region for absorbing the polarized light
    Patent number: 7268841
    Abstract: A display device 100 has a display unit 110 and a display switching unit 120. The display switching unit 120 is provided with a reflective polarizing plate 121, a liquid crystal panel 122, and a polarizing plate 123 arranged in this order from the side of the display unit 110 to the observation side. By controlling the liquid crystal panel 122, the display switching unit can be switched between a light transmissive state and a light reflective state. The display unit 110 and the display switching unit 120 are optically adhered to each other by an adhesive layer 131. Thus, deterioration of the contrast by boundary reflection can be restrained, and the flatness and the rigidity of the device can be improved.
