The invention relates to the field of display technology, and discloses an organic electroluminescence substrate and an organic electroluminescence display panel. The organic electroluminescence substrate comprises a flat layer; an insulating layer formed on the flat layer, the insulating layer has a plurality of an opening; a first electrode, the first electrode covers the bottom of the opening, the side of the opening and the surface of the insulating layer facing away from the flat layer, and the part of the first electrode located at the bottom of the opening and the side of the opening cooperates to form a reflective cup structure; In the pixel definition layer defining the pixel unit area, the surface of the pixel definition layer facing away from the flat layer is flush with the surface of the insulating layer facing away from the flat layer; formed on the side of the first electrode facing away from the flat layer and covering at least the first electrode at the bottom of the opening The organic light-emitting layer, the pixel definition layer is located between the organic light-emitting layer and the first electrode; the second electrode is formed on the side of the organic light-emitting layer away from the flat layer. The organic electroluminescent substrate improves the extraction efficiency of the reflective cup structure.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to an organic electroluminescence substrate and an organic electroluminescence display panel. Background technique [0002] In the prior art, such as figure 1 As shown, it is the conventional structure of the reflector cup of the organic electroluminescence substrate. The organic electroluminescence substrate includes a flat layer 01, an insulating layer 02, an anode 03, a pixel definition layer 04, an organic light-emitting layer 05, and a cathode 06. The reflector cup structure passes through The arrangement of the pad height structure on the insulating layer 02 enables the anode to form a reflective layer, which can effectively utilize the laterally propagated energy such as waveguide energy to couple to the outside of the device and improve the outcoupling efficiency of the device. [0003] However, when the waveguide energy propagates into the pixel-defining laye...
