Abstract

The invention provides an OLED display panel. The OLED display panel comprises a substrate, a first electrode, a partition wall and a scattering layer, wherein the partition wall is positioned between the substrate and the first electrode; and the scattering layer is formed on the substrate and is positioned in an area surrounded by the partition wall. According to the OLED display panel provided by the invention, the scattering efficiency of the scattering layer can be improved, so that the luminous efficiency can be strengthened, and the luminous performance is improved. The invention also provides a manufacturing method of the OLED display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a method for manufacturing the OLED display panel. Background technique [0002] In the current field of lighting and display, due to the characteristics of organic electroluminescence (OLED), such as low starting voltage, thinness, and self-luminescence, more and more researches are widely used in the development of lighting products and panel industries. In order to meet the requirements of low energy consumption, thinness and surface light source. [0003] At present, OLED emits light mainly through the recombination of excitons, and then exits from the light-emitting layer into the air. For general bottom-emitting OLED lighting devices, the path of light emission is: light-emitting layer-anode-substrate-air. After four paths, it can reach the human eyes incident in the air. [0004] The light exits from the light-emitting layer into the air. There...
