Abstract
The present application provides a display panel, a manufacturing method, and an electronic device. The electronic device comprises the display panel. The display panel comprises a light-emitting device layer, an encapsulation layer and a barrier film. First scattering particles are distributed in the encapsulation layer, and the light scattering effect of the first scattering particles on the light-emitting device layer can be employed to improve the viewing angle of the display panel. The barrier film comprises at least two antireflective layers with different refractive indexes to increase the transmittance of the barrier film, thereby improving the light extraction efficiency of the display panel.
