Abstract: A light-emitting substrate includes a first substrate, a reflective layer and support columns. The reflective layer is disposed on the first substrate and provided with first openings. At least for two of cross-sections, parallel to a place where the first substrate is located, of a first opening, an area of a cross-section relatively proximate to the first substrate is less than an area of a cross-section relatively away from the first substrate. The support columns are located on a side of the reflective layer away from the first substrate and fixed on the first substrate. An orthographic projection of a support column on the first substrate is a first projection, an orthographic projection a minimum cross-section of the cross-sections is a second projection, and the second projection lies within a range of the first projection.
