Display panel and display device

A display panel comprising:

• a substrate;
• a light emitting layer on a side of the substrate, comprising a plurality of light emitting units spaced apart, with a pixel definition layer among the light emitting units;
• a packaging layer on a side of the light emitting layer away from the substrate;
• lens elements on a side of the packaging layer away from the light emitting layer, wherein a projection of a lens element of the lens elements on the substrate overlaps at least partially with a projection of the pixel definition layer on the substrate, the lens element comprises a first lens and a second lens stacked in layers, the first lens is adjacent to the packaging layer, and the second lens is on a side of the first lens away from the packaging layer;
• a transparent layer on the side of the packaging layer away from the light emitting layer, wherein at least a portion of the transparent layer is between the lens elements, and a projection of the transparent layer on the substrate overlaps at least partially with a projection of a light emitting unit of the light emitting units on the substrate;
• wherein the transparent layer directly contacts sidewalls of both of the first lens and the second lens;
• wherein the lens element has a side surface in contact with the transparent layer, and a refractive index of the lens element at the side surface is smaller than a refractive index of the transparent layer.
