[0057] Figures 3A-3H It is a schematic cross-sectional view of the process flow of the manufacturing method of the organic electroluminescence display element according to the first embodiment of the present invention. Please refer to Figure 3A , firstly, a first substrate 210 is provided, and the first substrate 210 has a first electrode layer 220, and the first electrode layer 220 is, for example, made of a conductive metal material with high work function and high reflectivity . Generally speaking, the first substrate 210 can be any type of active array substrate or passive array substrate. Taking the active array substrate as an example, the first substrate 210 in this embodiment is, for example, a common TFT array substrate, and the first electrode layer 220 is formed by pixel electrodes on the TFT array substrate.

[0058] Please refer to Figure 3B Next, an organic functional layer 230 is formed on the first electrode 220. In addition to the organic electrolumines...

[0075] Figure 7 It is a schematic diagram of an organic electroluminescent display element according to a second embodiment of the present invention. Please refer to Figure 7 The main difference between this embodiment and the first embodiment is that the material of the microlens 272d in this embodiment is made of transparent material. In the present invention, the material of the microlens 272d can be selected according to the needs of the actual situation.

[0077] Please refer to Figure 8 , which is a schematic diagram of an organic electroluminescence display element according to a third embodiment of the present invention. The organic electroluminescence display element of this embodiment is similar to the first embodiment, and the main difference is that this embodiment uses a white light emitting layer 230W, which is different from the first light emitting unit 230R, the second light emitting unit 230R in the first embodiment. The second light emitting unit 230G and the third light emitting unit 230B. In this embodiment, the white light emitting layer 230W cooperates with the first microlens 272a, the second microlens 272b, and the third microlens 272c to achieve full-color display. The microlens 272 is located between the first substrate 210 and the second substrate 260 to prevent the microlens 272 from being damaged due to exposure to the external environment, and can also achieve the same effect as the first embodiment. ...
