LED light-emitting plate and display device

The invention relates to the technical field of display, in particular to an LED light-emitting plate and a display device.The LED light-emitting plate comprises a circuit layer, an insulating layer, a substrate and a plurality of LED chips, the insulating layer and the circuit layer are sequentially stacked on one side of the substrate, the LED chips are arranged on the side, away from the insulating layer, of the circuit layer, and the LED chips are arranged on the side, away from the insulating layer, of the circuit layer. The insulating layer and the circuit layer are internally provided with heat dissipation holes, and the heat dissipation holes are filled with phase change materials. The LED lamp has the effect of relieving insufficient heat dissipation of the LED light-emitting plate. 本申请涉及显示技术领域，尤其是涉及一种LED发光板及显示装置，其包括电路层、绝缘层、基板和多个LED芯片，所述绝缘层和所述电路层依次层叠于所述基板的一侧，所述LED芯片设置在所述电路层远离所述绝缘层的一侧，所述绝缘层和所述电路层内设置有散热孔，所述散热孔内填充有相变材料。本申请具有缓解LED发光板散热不足的效果。
