Patent ID: 8735876

Claim:
An organic light emitting diode display, comprising: a first electrode; a second electrode facing the first electrode; and an emission layer between the first electrode and the second electrode, wherein the first electrode comprises: a first layer comprising a material having a work function of about 4.0 eV or less and an electron injection material; and a second layer comprising a material having a resistivity of about 10 μΩcm or less, and the first layer is disposed between the second layer and the emission layer, wherein the electron injection material in the first layer is an oxide, a fluoride, a quinolate, or an acetoacetate compound of an alkali metal or an alkaline-earth metal, wherein the first layer comprises the material having the work function of about 4.0 eV or less mixed with the electron injection material in a weight ratio of about 100:1 to about 1:100.
