Claim 9:
10. A display apparatus, comprising an organic electroluminescent device,
wherein the organic electroluminescent device comprises: a plurality of pixels, wherein each of the plurality of pixels comprises at least a red sub-pixel, a green sub-pixel and a blue sub-pixel, and the plurality of pixels comprise:
a substrate comprising a red sub-pixel preparation region corresponding to the red sub-pixel, a green sub-pixel preparation region corresponding to the green sub-pixel, and a blue sub-pixel preparation region corresponding to the blue sub-pixel;
a reflective electrode layer formed on the substrate and comprises a red light reflective electrode located in the red sub-pixel preparation region, a green light reflective electrode located in the green sub-pixel preparation region, and a blue light reflective electrode located in the blue sub-pixel preparation region;
a transparent insulating layer located on a surface of a side of the red light reflective electrode facing away from the substrate, wherein an area of the transparent insulating layer is smaller than an area of the red light reflective electrode;
a transparent conductive layer located on a surface of a side of the transparent insulating layer facing away from the substrate, a transparent conductive layer located on a surface of a side of the red light reflective electrode facing away from the substrate and not covered by the transparent insulating layer, and a transparent conductive layer located on a surface of a side of the green light reflective electrode facing away from the substrate;
a pixel definition layer formed between adjacent sub-pixels;
an organic light-emitting structure located on a surface of a side of the transparent conductive layer facing away from the substrate, and a surface of a side of the blue light reflective electrode facing away from the substrate, wherein the organic light-emitting structure comprises at least an organic light-emitting layer;
a cathode, which is located on a surface of a side of the organic light-emitting structure facing away from the substrate; and
an encapsulation layer, which is located on one side of the cathode facing away from the substrate.
