Abstract: An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes red, green, and blue pixels. Each pixel includes a pixel electrode, a hole auxiliary layer formed over the pixel electrode, and an organic emission layer formed over the hole auxiliary layer. Each pixel also includes an electron auxiliary layer formed over the organic emission layer, and a common electrode formed over the electron auxiliary layer. Each of the red and green pixels further includes a host layer formed between the hole auxiliary layer and the organic emission layer and a resonance layer formed between the host layer and the organic emission layer.
