Abstract
An organic light emitting diode display including: a display panel; a first retarder on the display panel and including a first reactive liquid crystal; a second retarder on the first retarder and including a second reactive liquid crystal; and a polarizer on the second retarder, wherein a first optical axis of the first reactive liquid crystal is inclined by 2θ+45° relative to an absorption axis of the polarizer, and a second optical axis of the second reactive liquid crystal is inclined by θ relative to the absorption axis of the polarizer.
