ABSTRACT:
A liquid crystal display device is disclosed that is capable of preventing poor alignment caused by a column spacer to improve the contrast ratio. The liquid crystal display device includes a color filter and column spacers located between a first substrate and a second substrate. The column spacers maintain the cell gap between the first and second substrates. The color filter contains pixels having multiple sub-pixels of different colors. The column spacers in regions of sub-pixels of the same color are randomly formed within the regions.
