Problems solved by technology
However, the material properties of the transparent conductive layer are similar. When doing multi-layer etching, it is difficult to ensure the etching selectivity, resulting in over-etching, so that the transparent conductive layer that should not be etched is partially etched; When the upper film is on, the next film is easy to crystallize, making the film impossible to etch

The invention discloses a preparation method of a display panel, a display panel and a display device. Wherein, the preparation method of the display panel includes: providing a substrate; forming a red light reflective electrode located in a red sub-pixel, a green light reflective electrode located in a green sub-pixel, and a blue light reflective electrode located in a blue sub-pixel on the substrate; A transparent insulating layer is formed on the surface of the light reflective electrode away from the substrate side, wherein the area of the transparent insulating layer is smaller than the area of the red reflective electrode; the transparent insulating layer, the red reflective electrode not covered by the transparent insulating layer and the green reflective A transparent conductive layer is formed on the surface of the electrode away from the substrate. The invention solves the problem that the etching selectivity cannot be guaranteed when etching multiple transparent conductive layers in the prior art, avoids the partial etching of the transparent conductive layer that does not need to be etched in the prior art, and improves the optical adjustment layer. Etching precision.
Description
Technical field [0001] The embodiment of the present invention belongs to the field of display technology, and relates to a manufacturing method of a display panel, a display panel and a display device. Background technique [0002] The technology to realize the colorization of Organic Light-Emitting Diode (OLED) includes two mainstream technologies, namely microcavity effect RGB pixel independent light-emitting technology, and white light-emitting material with color filter technology. [0003] Microcavity effect RGB pixel independent light emission requires the use of sophisticated metal shadow mask and pixel alignment technology to prepare the red, green, and blue light-emitting center of the microcavity effect to achieve colorization. It requires the use of sophisticated metal shadow masks, while metal The shadow mask method is difficult to ensure the positioning accuracy of the sub-pixels, and it is more difficult to realize a display panel with high pixel density. Moreover, t...
