Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate; a pixel defining layer on the substrate, wherein the pixel defining layer comprises a plurality of pixel openings; a plurality of light-emitting elements which are corresponding to the plurality of pixel openings in a one-to-one manner; an optical layer located on the side, away from the substrate, of the pixel limiting layer, wherein the optical layer comprises a first optical structure and a plurality of second optical structures, and the vertical projection of the first optical structure on the plane where the substrate is located is overlapped with the vertical projection of the light-emitting element and the pixel limiting layer on the plane where the substrate is located; wherein the pixel openings comprise first pixel openings; the first pixel opening comprises a first long side and a first short side, and the length of the first long side is greater than that of the first short side; a second optical structure is arranged at a position corresponding to the first pixel opening; and the number of the second optical structures corresponding to the first short sides is greater than that of the second optical structures corresponding to the first long sides. The viewing angle attenuation brightness of the same sub-pixel in different directions can be the same, and the display effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people such as daily life and work, and has become an indispensable essential tool. [0003] The important part of electronic equipment to realize the display function is the display panel, but the current display panel generally has the problem of low luminous efficiency. Contents of the invention [0004] The present invention provides a display panel and a display device, which can not only improve the luminous efficiency of the display panel, but also make the attenuation brightness of the same sub-pixel the same in different directions in different directions, thereby improving the d...
