Summary:PURPOSE: An organic light emitting diode device is provided to improve the lifespan of an organic electro luminescence device by forming a first electronic transfer layer to control the mobility of electronics. CONSTITUTION: In an organic light emitting diode device, an anode(150) is arranged on a substrate. An organic film(160) is arranged in the anode layer. The organic film comprises a light-emitting layer(165), a first electron transfer layer(166), and a second electron-transport layer(167). The charge mobility of the first electron transfer layer is lower than that of the second electron transfer layer. A cathode(170) is arranged on the organic film.
