Abstract
A color film structure includes a black matrix, a color film layer and a reflective layer. The black matrix has a plurality of openings. The color film layer includes a plurality of filter portions, and at least a portion of each filter portion is located in an opening of the black matrix. The reflective layer is located on a side of the black matrix configured to be proximate to a light-emitting substrate, and an orthographic projection of the reflective layer on a plane where the black matrix is located is covered by the black matrix. The reflective layer is configured to reflect at least a part of light emitted from the light-emitting substrate to the black matrix back to the light-emitting substrate, so that at least a part of the light reflected back to the light-emitting substrate is emitted through the color film layer.
