The present invention provides an OLED color display device, comprising a substrate ( 1 ), an anode ( 11 ), a thin film transistor array ( 21 ), a Hole Injection Layer ( 22 ), a Hole Transport Layer ( 23 ), a light emitting layer ( 3 ), an Electron Transport Layer ( 24 ), a cathode ( 12 ), a package cover plate ( 2 ), a color conversion layer ( 4 ) and a seal frame ( 5 ); the light emitting layer ( 3 ) comprises a first light emitting layer ( 31 ) and the second light emitting layer ( 32 ), and both the first light emitting layer ( 31 ) and the second light emitting layer ( 32 ) are manufactured by host material doped with guest material, and the guest material comprises luminescent material and electron transport material; the first light emitting layer ( 31 ) is a blue light emitting layer, and the second light emitting layer ( 32 ) is a red, green lights commonly emitting layer, a yellow light emitting layer or a green light emitting layer; lights emitted by the first light emitting layer ( 31 ) and the second light emitting layer ( 32 ) synthesize white light or blue, green light possessing higher energy efficiency and luminescence efficiency. The power consumption is low. |
