Abstract
The present application provides a flexible display apparatus and a white light organic electroluminescent device including an anode, a first blue light emitting unit, a second yellow light emitting unit, a third blue light emitting unit, and a cathode successively laminated and disposed, wherein the second yellow light emitting unit including a red light emitting layer. The flexible display apparatus and a white light organic electroluminescent device provided by the application enhances the luminous intensity of the red light band in the three-laminated layer white light organic electroluminescent device by adding a red light emitting layer, and optimizes the spectrum of the white OLED device, when used as a display device it can reduce power consumption of the display apparatus.
