PURPOSE: An OLED(Organic Light Emitting Diode) display is provided to obtain a minimum ambient contrast ratio for both indoor and outdoor viewing. CONSTITUTION: An OLED display(10) has an ambient contrast ratio greater than ten at an ambient illumination greater than 6,000 lux at an average power of 100 milliwatts per centimeter squared. A top emitting body of a display includes a substrate(12), a TFT layer(14), an insulating layer(16), a first patterned electrode(18), and a second insulating layer(17). OLED layers(19R,19G,19B) are deposited upon the insulating layer(17) and first patterned metal electrodes(18). A common electrode(30) and a protection layer(32) are deposited above the OLED layers.
