The embodiment of the invention discloses a light-emitting panel and a light-emitting device. The light emitting panel includes a substrate; the light-emitting layer is arranged on one side of the substrate; the packaging layer is arranged on one side, far away from the substrate, of the light-emitting layer; the packaging layer comprises a heat dissipation layer, and the surface area of the heat dissipation layer is larger than that of the light-emitting layer. The light-emitting panel comprises a middle area and an edge area surrounding the middle area. The unit heat dissipation area of the heat dissipation layer located in the middle area is larger than the unit heat dissipation area of the heat dissipation layer located in the edge area. According to the technical scheme, the heat dissipation effect of the light-emitting panel is improved, and then the service life of the light-emitting panel is prolonged. 本发明实施例公开一种发光面板及发光装置。该发光面板包括基板；设置于基板一侧的发光层；设置于发光层远离基板一侧的封装层；封装层包括散热层，散热层的表面积大于发光层的表面积；发光面板包括中间区域和环绕中间
