1. A backlight assembly, comprising:
a light source substrate, a microstructure film layer and a backlight film material layer;
wherein the backlight film material layer is located on a light outgoing side of the light source substrate, and contains red quantum dots and green quantum dots;
the microstructure film layer is provided between the light source substrate and the backlight film material layer, and comprises a light transmission layer and a microstructure region; the microstructure region is provided at an edge position of the microstructure film layer; the microstructure film layer is configured to change, at the edge position, an outgoing angle of all or part of backlight passing through the microstructure region, so that all or part of the backlight passing through the microstructure region is deflected from a direction perpendicular to an edge where the microstructure region is located and is refracted away from a center of the microstructure film layer.
