Abstract

Embodiments provide an organic light emitting diode display. The display includes a substrate, a pixel electrode formed on the substrate, and an organic emissive layer formed on the pixel electrode. A common electrode is formed on the organic emissive layer. In addition, a crystallized light scattering layer is formed on the common electrode. The crystallized light scattering layer may be a crystallized organic or crystallized inorganic layer having a rough surface in order to effectively scatter light and prevent phenomenon, such as Newton's Rings from occurring in the display.

Description

technical field [0001] The present invention relates to an organic light emitting diode display, and more particularly, to an organic light emitting diode display having improved visibility and image quality. Background technique [0002] An organic light emitting diode (OLED) display generally has a plurality of organic light emitting diodes, each of which has a hole injection electrode, an organic emissive layer, and an electron injection electrode. In organic light emitting diode displays, electrons and holes generally recombine with each other in an organic emission layer, thereby generating excitons. When the excitons are transferred from an excited state to a ground state, energy is generated to emit light, and an image can be displayed based on the emitted light. [0003] Therefore, organic light emitting diode displays generally involve emissive characteristics, and unlike liquid crystal displays (LCDs), do not require a separate light source, and thus have reduced ...
