Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises a light-emitting device layer; and a light extraction thin film ; the light extraction thin film is arranged on the light emitting side of the light emitting device layer, and the light extraction thin film comprises nanofibers; compared with the prior art, the display panel has the advantages that the light extraction film is arranged on the light emitting side of the light emitting device layer, and the light extraction film comprises the nanofibers, so that the scattering effect on the light emitted by the light emitting device layer can be achieved, the microcavity effect and the total reflection effect in the display panel can be effectively reduced, and the light extraction efficiency of the display panel is further improved; and the visual angle of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device with the display panel. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel has the advantages of self-illumination, no need for backlight, high contrast, wide color gamut, thin thickness, fast response and can be used for flexible panels, especially top-emitting Due to its advantages such as high aperture ratio, OLED display panels are considered to be a new technology for next-generation flat display. [0003] However, for the existing top-emitting OLED display panel, there are relatively serious microcavity effects and total reflection effects, so the light extraction efficiency and viewing angle of the OLED display panel will be greatly affected. Contents of the invention [0004] Embodiments of the present invention provide a display pan...
