Abstract: The present disclosure provides an organic light emitting diode display device including: first to third color filter layers disposed corresponding to red, green, and blue sub-pixels, respectively; and a fourth color filter layer alternately arranged including a color layer having the same color as any one of the first to third color filter layers in a white sub-pixel in each of a plurality of pixels, and having a smaller height than the first to third color filter layers. Additional color filter layers may also be included. The display device of the present disclosure has lower reflectance and enhanced black color expression.
