Abstract
An organic light emitting diode (OLED) display includes: pixel electrodes formed on a substrate; a pixel definition layer between the pixel electrodes and partitioning a pixel area; organic emission layers of a plurality of colors on the pixel electrodes; and a common electrode on the organic emission layers. The pixel definition layer includes a first pattern and a second pattern having different formation materials, thicknesses, and extension directions.
