A backlight module is provided, including a light guide plate, an optical film, and a light source module. The optical film is disposed on the light guide plate and has an accommodating space. The light source module has at least one light-emitting surface, which can be divided into a light-emitting area and a frame area. The light-emitting area faces the light guide plate, and at least a portion of the frame area enters the accommodating space.

Backlight module and display device

A backlight module includes a light source, a light guide plate and a light-adjusting member. A light source chromaticity is measured from light generated by the light source. The light guide plate has a light-incident surface and a light-emitting surface. Light generated by the light source enters the light guide plate and emits out from the light-emitting surface. With the light-adjusting member, a first light guide plate chromaticity is measured from the light-emitting surface. There is a first difference value between the first light guide plate chromaticity and the light source chromaticity. Without the light-adjusting member, a second light guide plate chromaticity is measured from the light-emitting surface. There is a second difference value between the second light guide plate chromaticity and the light source chromaticity. The first difference value is different from the second difference value.

A light guide plate has a light exiting side, a reflection side opposite to the light exiting side, and a light entering side. A plurality of miniature diffusing entities, each having a curved surface and two slant surfaces extending from the two ends of the curved surface, are formed on the light entering side. The combination of the curved surface and the two slant surfaces cause light emitted from point-like light sources to have wider incident angles and be uniformly scattered into the light guide plate.
