Abstract

The invention discloses a display panel and a display device.The display panel comprises an array substrate, a plurality of light-emitting pixel units, a microlens layer and a passivation layer, the microlens layer comprises a plurality of microlenses and a plurality of openings, the openings are formed between every two adjacent microlenses and correspond to the light-emitting pixel units, the multiple openings comprise a plurality of first openings. in the plane direction of the display panel, the first opening comprises a main body part and at least one external expansion part, the main body part comprises a plurality of side edges, a corner is formed at the intersection position of every two adjacent side edges, the external expansion part is arranged at the corner, and the external expansion part is an arc-shaped convex surface. According to the display panel, the external expansion part is arranged at the corner to finely adjust the shape of the first opening on the basis of the pattern of the main body part, so that the light convergence effect of the micro lens is improved, and the luminous efficiency 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 and a display device. Background technique [0002] For an organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, in order to improve the luminous efficiency of the light-emitting device, reduce power consumption and prolong the service life, a micro-lens structure is used for light extraction. The microlens structure includes a plurality of microlenses, which are usually prepared by using a mask with a photolithographic pattern to form a microlens. However, the ultraviolet light diffracted into the mask will be more superimposed at the included angle of the photolithographic pattern, resulting in The etched taper angle will be greatly reduced and extended inward, affecting the light converging effect of the microlens structure. Contents of the invention [0003] Embodiments of the present invention provide a display panel and...
