Abstract
A light guide plate, a backlight module and a display device are disclosed. The light guide plate includes: a first optical path control layer, a second optical path control layer, and a light guide layer that are sequentially stacked. A plurality of prism structures are provided on a side of the first optical path control layer distal to the second optical path control layer. The first optical path control layer, the second optical path control layer, and the light guide layer all extend in a first direction. The first optical path control layer is configured to deflect the light that enters the first optical path control layer from the light guide layer through the second optical path control layer, so that the deflected light passes through the second optical path control layer and is emitted from the light exit surface of the light guide layer.
