| 摘要 |
The present invention relates to an improved organic light-emitting diode (OLED) device which comprises a first conductive layer, a first light-emitting material layer, a second light-emitting material layer, a second conductive layer, and at least one third light-emitting material layer, wherein the first conductive layer is adapted for being an anode substrate, moreover, by way of evaporation process, the first light-emitting material layer, the third light-emitting material layer, the second light-emitting material layer, and the second conductive layer are formed on the anode substrate in turns. Besides, the phenomenon of efficiency roll-off occurring in a high luminance region of the OLED device may be improved by adding the third light-emitting material layer between the first light-emitting material layer and the second light-emitting material layer. |
