Abstract

The present disclosure discloses a color film assembly, a display substrate and a method for fabricating the same, and a display apparatus. The color film assembly includes a quantum dot layer, and a filter layer on a light emitting side of the quantum dot layer. The filter layer includes filter units. Each of the filter units includes a first filter structure. A light emitting surface of the first filter structure has at least one converging structure. The quantum dot layer includes quantum dot units which are in one-to-one correspondence with the filter units. Each quantum dot unit includes at least one quantum dot structure. The quantum dot structures in each quantum dot unit are in one-to-one correspondence with the first filter structures in the corresponding filter unit.
