Abstract
The invention discloses a light-emitting unit, comprising a backplane and a light source provided on the backplane. The light source includes a plurality of sub light sources. The light-emitting unit further comprises light reflecting structures provided between the sub light sources. The light reflecting structures are configured to reflect the light radiating thereon from the sub light sources into the light-emitting direction of the light-emitting unit. Accordingly, the invention discloses a backlight module including the light-emitting unit and a display device including the backlight module. The backlight module in the invention is not only capable of improving a Hotspot phenomenon, but also capable of preventing the light source in the light-emitting unit from directly contacting with a light guide plate.
