The invention provides a light-emitting panel, a preparation method of the light-emitting panel, a lighting device and an automobile. The light-emitting panel comprises a display area and a non-display area surrounding the display area. The light-emitting panel further comprises a back plate, a light-emitting layer, a packaging adhesive layer and a cover plate which are sequentially arranged in a stacked mode. The packaging adhesive layer is located between the back plate and the cover plate and surrounds the display area, and light emitted by the light-emitting layer is emitted through the back plate. The backboard comprises a substrate and a light absorption layer located in a non-display area of the substrate. The light absorption layer is arranged around the display area, the orthographic projection of the light absorption layer on the substrate and the orthographic projection of the packaging adhesive layer on the substrate are at least partially overlapped, and the light absorption layer is configured to absorb lateral light irradiating towards the light absorption layer in the light emitting panel.

    本公开提供了一种发光面板及其制备方法、照明装置及汽车,该发光面板包括:显示区以及围绕显示区的非显示区。发光面板还包括:依次层叠设置的背板、发光层、封装胶层以及盖板。封装胶层位于背板与盖板之间且围绕显示区设置,发光层发出的光经过背板出射。背板包括:衬底基板以及位于衬底基板的非显示区的吸光层。吸光层围绕显示区设置,吸光层在衬底基板上的正投影与封装胶层在衬底基板上的正投影至少部分重叠,吸光层被配置为吸收发光面板中的朝向吸光层照射的侧向光。
