Abstract: PURPOSE: An organic light emitting device is provided to achieve improved efficiency of light emission by using NaCl as an electron injection medium. CONSTITUTION: An organic light emitting device comprises a cathode, an electron injection medium, an electron transport layer, a hole transport layer, and an anode. The electron injection medium is NaCl having a thickness of 1.0±0.4nm. Improved efficiency of light emission is accomplished and manufacturing cost is reduced by using NaCl rather than LiF as an electron injection medium.
