Embodiment Construction

[0029] 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 here 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, only some structures related to the present invention are shown in the drawings but not all structures.

[0030] As mentioned in the background technology, the existing display panels have color shift when viewed at a large viewing angle. The inventors have found through research that the reason for this problem is that as the viewing angle increases, the light-emitting units of different light-emitting colors emit light. The brightness of the light decays at different speeds, resulting in color cast.

[0031] Based on the above problems, this embodiment provides a display panel. figure 1 It is a schematic structural...

Abstract

Embodiments of the invention disclose a display panel and a display device. The display panel comprises a substrate and a light-emitting unit positioned on one side of the substrate, wherein the light-emitting unit comprises a first light-emitting unit and a second light-emitting unit; the light-emitting colors of the first light-emitting unit and the second light-emitting unit are different; thefirst light-emitting unit comprises a first electron-transporting layer; the second light-emitting unit comprises a second electron-transporting layer; and the refractive index of the first electron-transporting layer is different from that of the second electron-transporting layer. According to the technical scheme in the embodiments, the refractive index of the first electron-transporting layerof the first light-emitting unit is set to be different from the refractive index of the second electron-transporting layer of the second light-emitting unit, so that the brightness attenuation speedof light emitted by the first light-emitting unit and the brightness attenuation speed of light emitted by the second light-emitting unit are matched when the viewing angle is increased, the chromaticity of the display panel is consistent when the viewing angle is increased, and the color offset of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the display field, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, people have higher and higher requirements for the display performance of the display panel. However, the existing display panel has color shift when viewed at a large viewing angle. Therefore, improving the viewing angle shift of the display panel has become an urgent problem to be solved in the industry. . Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device to solve the problem of angular misalignment in the existing display panel. [0004] In order to achieve the above technical problems, the present invention adopts the following technical solutions: [0005] In a first aspect, an embodiment of the present invention provides a display panel, including a substrate and a light emitting ...
