<p>PURPOSE: An organic light emitting diode display is provided to improve the light emitting efficiency and the life cycle of the organic light emitting layer by restraining the deterioration of work function of a first electrode by comprising the first electrode including a second layer which has bigger work function. CONSTITUTION: A driving circuit part and an organic light emitting device(140) are positioned between a first substrate(110) and a second substrate(120). A first electrode(710) is located on surface of the first substrate. The first electrode is made of the multiple layer including first through Nth layers. An organic light emitting layer(720) is located on the surface of the first electrode.</p>
