Abstract

The invention discloses an OLED display panel, a manufacturing method of the OLED display panel and a display device, so as to simplify the process steps, improve the yield rate and improve the display efficiency. The OLED display panel includes a cover plate and a back plate arranged on the box, wherein: a plurality of color filter units are arranged in an array on the cover plate, and the gaps between each color filter unit are filled with auxiliary cathodes, the The auxiliary cathode includes a black matrix, a buffer layer, and a metal layer sequentially formed on the cover plate; a flat layer is formed on the auxiliary cathode and the color filter unit, and the flat layer has a plurality of openings corresponding to the auxiliary cathode; A plurality of spacers are formed on the flat layer corresponding to the auxiliary cathode, and the spacers are abutted and supported between the cover plate and the back plate; formed on the flat layer and the spacers The transparent electrode layer is connected to the auxiliary cathode through at least part of the openings; the color filter layer of the cover plate is opposite to the pixel area of ​​the back plate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, a method for manufacturing the OLED display panel, and a display device. Background technique [0002] Due to its thinness, lightness, wide viewing angle, active luminescence, continuously adjustable luminous color, low cost, fast response, low energy consumption, low driving voltage, wide operating temperature range, simple production process, high luminous efficiency and Flexible display and other advantages have been listed as a promising next-generation display technology. [0003] In order to realize the manufacture of high-pixel display screens and obtain high-definition and high-fidelity display images, the industry has proposed a scheme of combining Oxide BP with printed OLEDs to achieve top emission. The inventors found that because the top emission needs to cooperate with the p...
