  • Patent number: 10747064
    Abstract: A liquid crystal display (LCD) device is disclosed, which comprises a first substrate and a second substrate; a pixel electrode provided in each of the plurality of pixels on the first substrate; a common electrode provided on the first substrate; an auxiliary line connected to the common electrode; a column spacer provided between the first substrate and the second substrate; and moving stopper walls provided on the first substrate to restrict a moving range of the column spacer and spaced apart from the auxiliary line. As a moving range of the column spacer may be restricted by the moving stopper walls, an alignment direction of a liquid crystal layer is not changed by movement of the column spacer, whereby a spot defect of the LCD device may be avoided.
