Abstract
The present invention relates to an OLED display. In some embodiments, the OLED display may employ combinations of linear polarization, circular or elliptical polarization, and phase delay in order to suppress reflection from external light while minimizing the loss of emitted light from the OLED display. For example, the OLED in the display includes a stack having a first electrode, an organic emission layer, and a second electrode, a DBEF formed on the OLED, a first polarizing plate formed on the DBEF, a second polarizing plate formed on the first polarizing plate, and a plurality of phase delay plates formed between the first polarizing plate and the second polarizing plate.
