  • Patent number: 10185193
    Abstract: A liquid crystal pixel structure is disclosed. The liquid crystal pixel structure includes: a pixel electrode, located in a pixel aperture. The pixel electrode has two or more display domains applied with the same voltage level. The pixel electrode extends in different directions in the display domains. A gate line is located at an intersection of the display domains. An edge of the intersection of the display domains overlaps the gate line. A data line is located at an edge of the pixel aperture. The pixel electrode is controlled by the gate line and the data line via a transistor. The aperture of the pixel structure is divided by the gate lines. Therefore, the edge of the display domains overlaps the gate lines. The dark line can be covered by the gate lines and thus the aperture rate and the transparent rate can be raised.
