  • Publication number: 20140152928
    Abstract: A liquid crystal display device with controllable viewing angle of the present invention has an upper substrate on which an upper substrate common electrode is disposed, a lower substrate on which a pixel electrode is disposed, and a liquid crystal layer sandwiched between the upper and the lower substrates. The liquid crystal molecules are vertical to the upper substrate when no voltage is applied, and a plurality of strip-like lower substrate common electrodes are disposed on the lower substrate and arranged in parallel substantially. The upper substrate common electrode and the pixel electrode provide an electric field perpendicular to the upper substrate, to form a first viewing angle mode when a voltage is applied, the lower substrate common electrode and the pixel electrode provide an electric field perpendicular to the upper substrate to form a second viewing angle mode when a voltage is applied.

  • Publication number: 20130278862
    Abstract: A liquid crystal display device includes a plurality of pixel units. The pixel units include a reflection region and a transmission region. The space between the reflection region and the transmission region of adjacent pixel units is not more than 1 ?m in the direction parallel to the substrate. The gap between adjacent pixel units is utilized. As a result, the utilization ratio of display region of the liquid crystal display device is improved, and the effective area of the reflection region is increased. Accordingly, the display quality of the reflection region is improved without decreasing the transmission region, or the effective area of the transmission region is increased and the display quality of the transmission region is improved without decreasing the reflection region. Consequently, the aperture ratio of the liquid crystal display device is effectively improved.
