Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0024] figure 1 is a schematic structural diagram of a display panel in the related art, figure 2 Yes figure 1 Schematic cross-section along the AA' direction in the middle. like figure 1 and figure 2 As shown, the display panel 100 includes: a substrate 10, and a pixel defining layer 13 located on one side of the substrate 10. The pixel defining layer 13 includes a pixel opening 131 and also includes a light-emitting element 132; The first optical structure 141 is arranged above, and by arranging the first optical structur...

Abstract

The invention discloses a display panel and a display device. The display panel includes a substrate; a pixel defining layer on the substrate; the pixel defining layer includes a plurality of pixel openings; a plurality of light-emitting elements are arranged in a one-to-one correspondence with the plurality of pixel openings The optical layer on the side of the pixel-defining layer away from the substrate; the optical layer includes 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 related to the light-emitting element and the pixel-defining layer. The vertical projections of the plane where the bottom is located overlap; wherein, the pixel opening includes a first pixel opening; the first pixel opening includes a first long side and a first short side, and the length of the first long side is greater than the length of the first short side; A second optical structure is disposed at a position corresponding to the pixel opening; and the number of the second optical structures corresponding to the first short side is greater than the number of the second optical structures corresponding to the first long side. The viewing angle attenuation brightness of the same sub-pixel in different directions can be made the same, and the display effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, 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 function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable part of today's people. important tool that is missing. [0003] An important component of an electronic device to achieve a display function is a display panel, but the current display panel generally has the problem of low luminous efficiency. SUMMARY 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 viewing angle attenuation brightness of the same sub-pixel in different directions the same,...
