Organic light emitting diode display

摘要

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.

1. An organic light emitting diode (OLED) display device, comprising:
a substrate; a light path guide layer formed on the substrate and having an inclined side wall on a major surface of the substrate; an organic light emitting diode (OLED) including a first electrode and a second electrode, each of the first electrode and the second electrode having an inclined side wall which is formed on and in parallel with the inclined side wall of the light path guide layer; a phase transition layer formed on the OLED and formed only to correspond to the inclined side walls of the first electrode, the second electrode and the light path guide layer, the phase transition layer comprises a semi-transmissive film and a phase transition film located between the inclined side wall of the second electrode and the semi-transmissive film, the phase transition film operatively cooperating with the inclined side wall of the second electrode so that a light reflected from the inclined side wall of the first electrode has a phase transition of 180 degrees attributed to the phase transition film; and a pixel defining layer formed on the light path guide layer to cover an edge of the first electrode.
