Display panels and display devices

A display device, comprising a display panel, the display panel comprising a plurality of light emitting areas arranged at intervals and a non-light emitting area located between the light emitting areas, and the display panel comprising:

• a substrate;
• a pixel definition layer, disposed on a side of the substrate, and comprising first grooves correspondingly disposed in the light emitting areas and second grooves disposed in the non-light emitting area;
• a plurality of partitions, disposed in the non-light emitting area and on a side of the pixel definition layer away from the substrate, wherein each of the partitions comprises a first portion disposed corresponding to one of the second grooves and a second portion disposed on a side of the first portion away from the substrate, a width of the second portion is greater than a width of the first portion, and the second portion is spaced apart from a surface of the pixel definition layer away from the substrate;
• and
• a light emitting layer, disposed on the side of the pixel definition layer and sides of the partitions away from the substrate, wherein the light emitting layer comprises pixels disposed corresponding to the first grooves, the light emitting layer comprises pixels a plurality of sub-film layers stacked, and at least part of the sub-film layers of the light emitting layer are disconnected at the partitions.
