Claim Text:
1. A color display device structure, comprising a substrate, an anode formed on the substrate, a thin film transistor array formed on the anode, a hole injection layer formed on the thin film transistor array, a hole transport layer formed on the hole injection layer, a light emitting layer formed on the hole transport layer, an electron transport layer formed on the light emitting layer, a cathode formed on the electron transport layer, a cover plate set above the cathode and bonded to the substrate, a color conversion layer formed on the inner side of the cover plate, and a sealant used to encapsulate the substrate and the cover plate, wherein the light emitting layer is a blue and green light emitting layer, the color conversion layer includes a blue filter unit, a green filter unit and a red conversion unit separated one another, the blue light and the green light emitted by the blue and green light emitting layer is filtered to become blue light by the blue filter unit, the blue light and the green light emitted by the blue and green light emitting layer is filtered to become green light by the green filter unit, and the blue light and the green light emitted by the blue and green light emitting layer is converted to red light by the red conversion unit, in order to achieve color display.
