Abstract

The invention provides a backlight module and a display device, and belongs to the technical field of display. The backlight module provided by the invention comprises a first base, a peep-proof groove and a first light-emitting device, wherein the peep-proof groove is arranged in the first base, and the first light-emitting device is arranged in the peep-proof groove; and the peep-proof groove isprovided with a plurality of side faces, each side face has a first preset included angle relative to the plane where the first base is located, and the included angle satisfies the condition that the light emitted by the first light-emitting device is limited within the preset visible angle range for outgoing. According to the technical scheme, by unitizing the side faces of the peep-proof groove, the light emitted by the first light-emitting device is limited within the visible angle range, so that people out of the visible angle range can not receive the light emitted by the first light-emitting device, and thus the anti-peeping function is realized.
