  • Patent number: 9029876
    Abstract: There is provided a pixel structure of a liquid crystal panel including a transparent substrate, and a gate line, a data line, a switching transistor, a first electrode, a second electrode and a shield layer formed on the transparent substrate. The gate line is substantially perpendicular to the data line. The switching transistor is located adjacent to a crossing point of the gate line and the data line, and is configured to input a display voltage of the data line to the second electrode according to the control of the gate line. The first electrode and the second electrode are arranged in such a way that the display voltage forms a transverse electric field between the first electrode and the second electrode. The shield layer overlaps at least a part of the gate and is electrically isolated from the first electrode and the second electrode.

  • Publication number: 20120081639
    Abstract: A liquid crystal display device includes a first polarization plate, a first birefringent film atop the first polarization plate, an optically compensated bend mode (OCB-mode) cell atop the first birefringent film, a refractive film atop the OCB-mode cell, a second birefringent film atop the refractive film, and a second polarization plate atop the second birefringent film. With this structure, any phase retardation of polarized light occurred during the propagation of the polarized light from the first polarization plate to the second polarization plate is compensated by the first birefringent film, the refractive film, and the second birefringent film and a substantially cross-shaped radiation pattern of full viewing angle is obtained in an actual measurement at the light outgoing surface of the liquid crystal display device, proving the liquid crystal display device has effectively improved the problem of restricted viewing angle and provides good optical performance.
