The circular polarizer may be omitted from a display to increase efficiency. A polarizer-free display may use other non-polarizer techniques to mitigate reflections of ambient light and mitigate diffraction reflection artifacts. The polarizer-free display may include a black pixel definition layer that absorbs ambient light. Color filter elements may be included in a black matrix to mitigate ambient light reflections. An intra-anode phase shift layer and/or an inter-anode phase shift layer may be included in the display to mitigate diffractive reflection artifacts. Multiple sub-pixels of the same color may be used in a single pixel to ensure a neutral reflection color. The display may include a cathode layer that is patterned to have openings over the black pixel definition layer to mitigate reflections. The display may include diffusive particles (in the color filter element or in a separate diffuser layer) to mitigate diffractive reflection artifacts.
