Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel includes: a substrate; an array layer that is positioned on one side of the substrate; the light-emitting structure layer that comprises a plurality of sub-pixels, and the sub-pixels comprise a first sub-pixel and a second sub-pixel which have the same color; a plurality of first and second adjusting parts, wherein the vertical projections of the first adjusting parts and the first sub-pixels corresponding to the first adjusting parts on the substrate are at least partially overlapped, and the vertical projections of the second adjusting parts and the second sub-pixels corresponding to the second adjusting parts on the substrate are at least partially overlapped, and wherein the phase difference of the light rays with the same phase after passing through the first adjusting part and the second adjusting part is greater than zero. According to the invention, theproblem that in the prior art, after external light is reflected by the anode layers of the sub-pixels with the same color, the light emitted from the light emitting surface of the display panel is subjected to grating diffraction, so that the display effect of the display panel is influenced is solved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Organic Light Emission Diode (OLED) display is a self-emissive display that uses organic light emitting diodes for light to display images. Features, at the same time has the advantages of high definition, wide viewing angle, and fast response speed. [0003] In order to reduce the reflectivity of external light in the OLED display, a circular polarizer is usually attached to the light-emitting surface of the OLED display in the prior art, but the circular polarizer will reduce the light-emitting effect of the OLED display. [0004] Therefore, instead of attaching a circular polarizer to the light-emitting surface of the organic light emitting diode display, color resistance is provided. A blue color resist is set at the corresponding part of the sub-pixel to improve the light emitting effect ...
