ORGANIC LIGHT EMITTING DISPLAY DEVICE INCLUDING A FIRST SUB PIXEL, A SECOND SUB PIXEL, AND A THIRD SUB PIXEL WITH DIFFERENT COLORS

摘要

PURPOSE: An organic light emitting display device is provided to prevent discoloration by forming an electron acceptor layer between a first organic light emitting layer and a third organic light emitting layer and between a second organic light emitting layer and the third light emitting layer to trap extra electrons.;CONSTITUTION: A first electrode(110) is formed on a substrate(101). A second electrode(150) faces the first electrode. An organic light emitting layer(130) is formed between the first electrode and the second electrode. The organic light emitting layer includes a first organic light emitting layer(131), a second organic light emitting layer(132), and a third organic light emitting layer(133). A hole transport layer(122) is formed between the first electrode and the organic light emitting layer. An electron acceptor layer(125) is contacted with the organic light emitting layer between the first electrode and the second electrode.;COPYRIGHT KIPO 2013
