Abstract
An organic light emitting diode (OLED) display includes a substrate, a light path guide layer formed on the substrate and having an inclined side wall, an organic light emitting diode (OLED) formed on the substrate and the light path guide layer, and a phase transition layer formed on the OLED and formed so as to correspond to the inclined side wall. Therefore, in the OLED display, the phase transition layer is formed in the light path guide layer so that it is possible to minimize external light reflectance increased by the light path guide layer.
