The invention provides a light-emitting substrate, a lighting device and an automobile. The light-emitting substrate comprises a substrate body, a light-emitting layer and a light-emitting layer, the light-emitting devices are arranged on the substrate, each light-emitting device comprises a first electrode, a light-emitting functional layer and a second electrode, the first electrode is a transparent electrode, and the second electrode is a reflecting electrode; the metal wire is arranged on the substrate; the first dimming layer and the second dimming layer are arranged on the metal wire, the first dimming layer is closer to the metal wire than the second dimming layer, and the refractive index of the first dimming layer is larger than that of the second dimming layer; the orthographic projection of the adjacent interface of the first dimming layer and the second dimming layer on the substrate is at least partially overlapped with the orthographic projection of the metal wire on the substrate, so that at least part of light emitted from the light-emitting device and reflected by the metal wire is totally reflected at the adjacent interface.

    本公开提供了一种发光基板、照明装置以及汽车,该发光基板包括:衬底基板;设置在衬底基板之上的多个发光器件,发光器件包括:第一电极、发光功能层以及第二电极,第一电极为透明电极,第二电极为反射电极;设置在衬底基板之上的金属走线;设置在金属走线之上的第一调光层和第二调光层,第一调光层相比于第二调光层更靠近金属走线,第一调光层的折射率大于第二调光层的折射率,第一调光层与第二调光层的邻接界面在衬底基板上的正投影与金属走线在衬底基板上的正投影至少部分重叠,以使得至少部分从发光器件发出后,被金属走线反射的光线,在邻接界面处时发生全反射。
