Abstract

The invention discloses a display panel, a manufacturing method of the display panel and a display device. The display panel includes: a substrate; a light emitting element layer, which is located onthe substrate, and includes a plurality of light emitting elements; and a light adjustment layer, which is located at a light output side of the light emitting element layer, and includes a black matrix and a plurality of light filtering units, wherein the black matrix includes a plurality of openings, at least a part of each light filtering unit is disposed at an opening, the plurality of light filtering units respectively correspond to positions of the plurality of light emitting elements, and surfaces which are of at least partial light filtering units and face away from the light emittingelement layer are diffuse reflection surfaces. According to the display panel of the embodiment of the invention, a reflection effect of the light adjustment layer on ambient light is reduced, and appearance feeling of the display panel is improved. In addition, the diffuse reflection surfaces can carry out at least partial total reflection on ambient light, which is reflected by partial structures of the light emitting elements, to the black matrix, and the black matrix absorbs the partial light, and thus the reflection effect of the display panel on the ambient light is further reduced.

Description

technical field

[0001] The present invention relates to the display field, in particular to a display panel, a manufacturing method of the display panel and a display device. Background technique

[0002] During the production process of the display panel, a circular polarizer is usually arranged outside the display surface to reduce the luminous flux of ambient light entering the display panel, thereby alleviating the problem of color shift or contrast caused by the reflection of ambient light inside the display panel.

[0003] Circular polarizers are generally thicker, which is not conducive to thinning and thinning display panels. The inventors have found that the circular polarizer can be replaced by a black matrix and filter structure to reduce the luminous flux of ambient light entering the display panel. However, the black matrix and the filter structure still have a certain reflectivity, which affects the look and feel of the display panel. Contents of the inventi...
