Abstract: A display module is provided. The display module includes a light modulation layer, and the light modulation layer is located between a color film layer and a display substrate. The light modulation layer includes a plurality of modulation portions, and a modulation portion is correspondingly disposed between a light-emitting portion and a color film portion. The modulation portion includes a modulation structure and a transmission structure. The color film portion includes a first region and a second region. An orthogonal projection of the transmission structure on the corresponding color film portion is located within the first region. The second region is adjacent to another color film portion of a different color, and an orthogonal projection of the modulation structure on the corresponding color film portion is located in the second region. The modulation structure is used to converge exit light of the corresponding light-emitting portion.

Abstract: A display base board, a display device and a manufacturing method of the display base board are provided. The display base board includes: a substrate (10); a light emitting layer (20), wherein the light emitting layer (20) includes a plurality of sub-pixels (201); a packaging layer (30); and at least one lens layer (40), wherein each of the at least one lens layer (40) includes a plurality of lens units (401), and the plurality of lens units (401) correspond to the sub-pixels (201) one to one.
