Abstract
An organic light emitting diode (OLED) display is provided. The OLED display has a plurality of pixel regions and comprises a substrate, a first electrode layer formed on the substrate, a second electrode layer formed on the first electrode layer, a pixel defining layer, and a light absorption composite layer. The pixel regions are separated by the pixel defining layer. The light absorption composite layer is formed on the substrate, and absorbs a light with wavelength of 380˜780 nm. The light absorption composite layer comprises a first light absorption layer and a second light absorption layer stacked together. The first light absorption layer absorbs a light with shorter wavelength. The second light absorption layer absorbs a light with longer wavelength different from that of the light absorbed by the first light absorption layer in the region of 380˜780 nm.
