Abstract: A display device includes: a base substrate, on which first and second light blocking areas extending in first and second directions, respectively, and a pixel area are defined; a gate line above the base substrate in the first light blocking area; a data line above the base substrate in the second light blocking area; thin film transistors connected to the gate and data lines; a color filters above the base substrate in the pixel area, where the color filters have an island shape; a step-difference compensation portion above thin film transistors; a pixel electrode above the color filter in the pixel area; a black matrix above the step-difference compensation portion in the first light blocking area; and main and sub column spacers protruding from the black matrix and spaced apart from each other. The main column spacer overlaps the step-difference compensation portion.
