    Abstract: A display apparatus includes a display panel including a driving part arranged along one side of the display panel, the display panel including a plurality of first gate lines that zigzag across the display in a diagonal direction between the first and second directions by alternately extending in the first and the second directions. The display device includes a first display area and a second display area, pixels within the first display area always receiving gate signals from a driving part connected to an end of the first gate lines. Within the second display area, a second gate lines extending in the first direction may be electrically connected to the first gate lines that relay gate signals to the first gate lines. This results in a reduced peripheral area of the display area, so that many displays can be combined together to produce a single image.

  • Patent number: 9086587
    Abstract: In a liquid crystal display (LCD), a thickness of a passivation layer overlapping signal lines is larger than a thickness of portion of the passivation layer not overlapping signal lines. A spacer may be formed to overlap the signal lines. In an aperture region of the LCD, a thickness of the passivation layer between a common electrode and a pixel electrode is relatively small, and therefore, it may be possible to prevent reduction in the intensity of the electric field between the common electrode and the pixel electrode. Since thickness of the passivation layer may be relatively large, it may be possible to prevent a signal delay of common voltage. A spacer may be formed overlapping signal lines with relatively thick passivation layer. The spacer may have a small height. Cell gap may be adjusted to be uniform, and prevent reduction in aperture ratio of the LCD.

  • Patent number: 8730422
    Abstract: A liquid crystal display uses a layout which reduces the number of data lines relative to the number of pixel columns by providing one data line for every two pixel columns. The display is structured to prevent a passivation layer from becoming opaque due to a manufacturing haze effect by forming the pixel electrode below a gate insulating layer. It is structured to prevent a drain electrode from being damaged due to an etchant used for patterning the pixel electrode. Further, it is structured to prevent a short circuit between a common voltage line and a gate line while not substantially reducing an aperture ratio by disposing a common voltage contact hole for electrically connecting the common voltage line with a common electrode between vertically extending portions of two gate lines that generally extend horizontally.
