  • Patent number: 9151994
    Abstract: A display panel includes a first substrate, scan lines, data lines, pixel units, a second substrate, a display medium, and a color filter layer. The scan lines and the data lines are disposed on the first substrate. The pixel units are electrically connected to the scan lines and the data lines. Each pixel unit includes first, second, third, and fourth pixels. An extension direction of slit patterns of the first and second pixels is different from an extension direction of at least one of slit patterns of the third and fourth pixels. The color filter layer includes a first color filter pattern disposed corresponding to the first pixel, a second color filter pattern disposed corresponding to the second pixel, and a third color filter pattern disposed corresponding to the third pixel and the fourth pixel.

  • Patent number: 9007555
    Abstract: A liquid crystal display panel including a first substrate, scan lines extending along a first direction, data lines, active devices, pixel electrodes, common electrodes, a second substrate and a liquid crystal layer is provided. The pixel electrodes are respectively disposed in sub-pixel regions and coupled to the corresponding active devices. The common electrodes are respectively disposed corresponding to the pixel electrodes. Each common electrode or each pixel electrode includes plural stripe electrodes arranged side by side. Each stripe electrode includes a first section and a second section respectively disposed on two opposite sides of a reference axis, wherein a major axis of the first section forms an included angle with a major axis of the second section. The included angles of the stripe electrodes in each sub-pixel region are gradually varied along the first direction. The liquid crystal layer is disposed between the first substrate and the second substrate.
