ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE |
摘要 |
An organic electroluminescent display device is disclosed which includes a lower substrate including a first substrate defined into red, green and blue sub-pixel regions, first and second switching elements formed in the red and green sub-pixel regions, first and second anodes each connected to the first and second switching elements, and a first organic light emission layer entirely formed on the first substrate provided with the first and second anodes; and an upper substrate including a second substrate, red and green color filter layers formed on the second substrate corresponding to the red and green sub-pixel regions, a third switching element formed on the second substrate corresponding to the blue sub-pixel region, a third anode connected to the third switching element, and a second organic light emission layer entirely formed on the second substrate provided with the red and green color filter layers and the third anode. |

1. An organic electroluminescent display device comprising:
first through third switching elements formed in red, green and blue sub-pixel regions into which a substrate is defined, respectively; a passivation layer entirely formed on the substrate which is provided with the first through third switching elements; red and green color filter layers formed on the passivation layer corresponding to the red and green sub-pixel regions; first and third anodes formed in the red, green and blue sub-pixel regions, respectively; an organic light emission layer pattern formed on the substrate which is provided with the first through third anodes; a first cathode formed on the organic light emission layer pattern; an organic light emission layer formed on the substrate which is provided with the first cathode; and a second cathode formed on the organic light emission layer. |
