<p>PURPOSE: An LED(Light Emitting Device) is provided to improve electron injection property without exerting any effect on the characteristics of a TFT(Thin Film Transistor). CONSTITUTION: An LED comprises an anode(102), a cathode(104), and an organic compound layer(103) formed between the anode and the cathode. The organic compound layer(103) further includes a hole transport layer(111), a light emitting layer(112), an electron transport layer(113) and an electron transmission region(114). At least portion of the electron transport layer(113) is connected to the cathode(104) through the electron transmission region(114). The electron transmission region(114) including donor molecule is connected to the cathode.</p> |
