Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a panel body and a heat dissipation layer. The panel body comprises a first main body part, the heat dissipation layer is located on one side of the panel body, the heat dissipation layer comprises a first heat dissipation part corresponding to the first main body part, and the surface of the side, away from the panel body, of the first heat dissipation part is a non-flat surface, so that the surface area of the first heat dissipation part is increased; and therefore, the contact area between the heat dissipation layer and the outside is increased, heat generated in the display panel can be conducted to the outside of the display panel more quickly through the first heat dissipation part, and the problem of poor heat dissipation of the first main body part of the display panel is solved. The problem of abnormal display of the display panel caused by poor heat dissipation can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In order to avoid the interference of electromagnetic, heat and other factors on the display panel, a heat dissipation layer will be provided on the back of the display panel to realize the functions of force buffer protection, electromagnetic shielding, and heat dissipation. In the heat dissipation layer, the copper foil for shielding and heat dissipation is located on the outermost side, and the heat released by the driver chips and circuit boards of the display panel needs to pass through the multi-layer film layers in the heat dissipation layer and then be transferred to the copper foil. Therefore, if the material of the heat dissipation layer is not properly selected, and the bonding between the heat dissipation layer and the display panel is not good, it will lead to uneven heat conduction, which...
