Problems solved by technology

In the case of a large viewing angle, the light L01 emitted by the display panel has an attenuation phenomenon, and because the wavelengths of different colors of colored light are different, the degree of attenuation of different colored lights is different. In the case of a large viewing angle, color shift is prone to occur, which affects the display effect

Abstract

The invention discloses a display panel and a display device, belonging to the technical field of display, comprising: a substrate; a driver device layer, a light emitting device layer, an encapsulation layer and a light scattering layer arranged on the substrate; a light emit device layer include a plurality of first color light emitting units and a plurality of second color light emitting unit.The wavelength of the first color light emitted by the first color light emitting unit is lambda 1, and the wavelength of the second color light emitted by the second color light emitting unit is lambda 2, lambda 2 (lambda 1; a light scatter layer include a plurality of light scattering units; a light scattering unit overlapping with the first color light emitting unit in a direction perpendicularto the substrate is a first light scattering unit. In the first light scattering unit, the distribution density of scattering particles in the substrate is Rho 1, and the relative refractive index ofthe scattering particles is N1; Where 5% <= Rho 1 <= 30% and/or N 1 >= 0. 5. The invention can improve the color deviation phenomenon of the display panel, thereby improving the display quality of the display panel.

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-emitting diodes are widely used in the fields of display and lighting due to their advantages of high contrast, fast response, and self-illumination. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a display panel provided by the prior art. The normal of the plane where the display panel 01 is located is the normal F1. [0004] When the user uses the display panel, the line of sight E1 is usually perpendicular to the display panel 01 , or approximately perpendicular to the display panel 01 , and in this case, the line of sight E1 is parallel to the normal line F1 of the display panel 01 . [0005] In the case of a large viewing angle, there is an angle β between the line of sight E2 and the normal F1 of the display panel 01 , and the larger the value o...
