A color filter substrate has unit pixels each having an area of 0.1 mm2 or more. Each unit pixel is formed of sub-pixels having a different color from one another and having areas that are substantially equal to one another. Each sub-pixel is formed of a continuous planar region having a maximum line width that does not exceed 150 μm. The sub-pixels are configured with a shape such that the sub-pixels form a preselected engagement pattern via which the adjacent sub-pixels engage one another.
