摘要： There are provided a backlight assembly (1) and a display device, the backlight assembly (1) includes a light source substrate (10), a microstructure film layer (30) and a backlight film material layer (20); the backlight film material layer (20) is located on a light outgoing side of the light source substrate (10), the microstructure film layer (30) is provided between the light source substrate (10) and the backlight film material layer (20), the microstructure film layer (30) includes a light transmission layer (301) and a microstructure region (302); the microstructure region (302) is provided at an edge position of the microstructure film layer (30). The combination of the microstructure region (302) and the light transmission layer (301) can change, at the edge position, an outgoing angle of all or part of backlight passing through the microstructure region (302), so that all or part of the backlight passing through the microstructure region (302) is deflected from a direction perpendicular to the edge where the microstructure region (302) is located and is refracted away from a center of the microstructure film layer (30), thereby an optical path of the backlight with the changed outgoing angle when passing through the backlight film material layer (20) is increased, more red light and green light are excited, and thus a problem of uneven chromaticity of a bluish edge of the backlight during full screen displaying is solved.
