Patent ID: 8169386

Claim:
An organic light emitting diode display, comprising: an organic light emitting diode comprising i) a pixel electrode, ii) an organic emission layer formed on the pixel electrode, and iii) a common electrode formed on the organic emission layer; a dual brightness enhancement film formed over the common electrode of the organic light emitting diode; a first phase delaying plate formed on the dual brightness enhancement film; a corner cube film formed on the first phase delaying plate; a second phase delaying plate formed on the corner cube film; and a polarizing plate formed on the second phase delaying plate, wherein at least one of i) the dual brightness enhancement film, ii) the first phase delaying plate, iii) the second phase delaying plate and iv) the corner cube film is configured to reduce reflection of external light incident onto the polarizing plate and/or reduce the loss of light emitted from the organic emission layer before outputting the emitted light through the polarizing plate.
