Abstract:
1. An organic light emitting diode (OLED) display comprising: a first substrate; an organic light emitting diode formed over the first substrate, the organic light emitting diode comprising a reflective surface configured to reflect light incident to the organic light emitting diode; a pixel defining layer formed over the first substrate, the pixel defining layer defining a light emitting region and a non-light emitting region of the display; a phase delay capping layer formed over the organic light emitting diode, configured to input linearly polarized light and output circularly polarized light, wherein the phase delay capping layer conforms to a shape of the organic light emitting diode and wherein an upper surface of the phase delay capping layer is lower with respect to a light emitting surface in the light emitting region of the display than in the non-light emitting region of the display; a second substrate disposed over the phase delay capping layer; and a polarizing plate formed over the second substrate, configured to pass through only linearly polarized light.
