Abstract

The invention provides a color display device structure, including a substrate (1), an anode (21), a thin film transistor array (23), a hole injection layer (24), a hole transport layer (25), a light emitting layer (26), an electron transport layer (27), a cathode (28), a cover plate (3), a color conversion layer (4) formed on the inner side of the cover plate (3), and a sealant (6). The light emitting layer (26) is a blue and green light emitting layer (26). The color conversion layer (4) includes a blue filter unit (41), a green filter unit (43) and a red conversion unit (45) separated one another. The blue light and the green light emitted by the blue and green light emitting layer (26) is filtered to become blue light by the blue filter unit (41). The blue light and the green light emitted by the blue and green light emitting layer (26) is filtered to become green light by the green filter unit (43). The blue light and the green light emitted by the blue and green light emitting layer (26) is converted to red light by the red conversion unit (45). The color display is achieved by the color display device structure. The color display device structure is manufactured by a simple …
