Color filter substrate and liquid crystal display device including the same

A color filter substrate according to the present invention includes: a substrate on which a pixel area is defined; a black matrix which is formed on the upper side of the substrate and includes an opening part corresponding to the pixel area; a color filter layer which is formed on the upper side of the substrate and includes red, green, and blue color filters which are successively arranged in a first direction to correspond to the pixel area; and a first column spacer and a second column spacer which are formed on the upper side of the black matrix and include different heights. The height of the first column spacer is higher than the height of the second column spacer. The arrangement density of the first column spacer is lower than the arrangement density of the second column spacer.
