<p>PURPOSE: An organic light emitting diode display is provided to improve image quality such as visibility by suppressing external reflection and increasing light emitting efficiency. CONSTITUTION: A first substrate(51) comprises a thin film transistor and an organic light emitting device. A second substrate(52) is arranged with facing the first substrate. A channel pattern(522) is formed on the surface of the second substrate that faces with the first substrate. The channel pattern has a striped shape. The organic light emitting device(L1) is classified into a light emitting region and a non-light emitting region.</p>
