  • Liquid crystal display panel
    Patent number: 8767162
    Abstract: The present invention relates to a liquid crystal display panel, which can prevent a Mura from forming at the time of physical impact or vibration for improving a display quality. The liquid crystal display panel can include an upper substrate having a plurality of column lines formed thereon, a lower substrate having a plurality of row lines formed thereon perpendicular to the plurality of column lines, a pixel region formed at each crossed region of the plurality of column lines and the plurality of row lines, and column spacers each formed between the upper substrate and the lower substrate for maintaining a cell gap between the upper substrate and the lower substrate, wherein the column spacers formed at a first region of a display region adjacent to a liquid crystal injection have dot shapes.
    Type: Grant
