Abstract

The invention discloses a display panel, a manufacturing method of the display panel and a display device. The display panel comprises a plurality of first color sub-pixels, a plurality of second color sub-pixels, a plurality of third color sub-pixels, a packaging layer and a refractive index adjustment layer, wherein each sub-pixel includes an organic light emitting diode, and the organic light emitting diode includes an anode; the packaging layer covers the organic light emitting diode; and the refractive index adjustment layer is located at the side, which deviates from a substrate, of theanode of each organic light emitting layer, the refractive index of the third color sub-pixels is less than the refractive index of the first color sub-pixels and is less than the refractive index ofthe second color sub-pixels. The refractive index adjustment layer is arranged at the side, which deviates from the substrate, of the anode of each organic light emitting diode, so that the display panel is enabled to have a good observation angle of view in each area, the color deviation of the display panel in the case of a large view of angle is reduced, and the display performance of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a method for manufacturing the display panel, and a display device. Background technique [0002] A display panel provided by the prior art has a problem of color cast under a large viewing angle, for example, when the display panel is in a white picture, the entire display panel has a problem of bluish cast. Contents of the invention [0003] In view of this, the present invention provides a display panel, including: a base substrate; a plurality of sub-pixels arranged on the base substrate, the plurality of sub-pixels include a plurality of first color sub-pixels, a plurality of second color sub-pixels and A plurality of third color sub-pixels, each sub-pixel includes an organic light emitting diode, the organic light emitting diode includes an anode; an encapsulation layer, the encapsulation layer covers the organic light emitting diode; a ...
