Abstract
Backlight module and display device are disclosed. The backlight module includes a light source structure and a light guide plate, which includes a body structure and a wedge-shaped structure disposed on the body structure and located at a side adjacent to the light source structure. The body structure includes a light incident surface of body structure. The wedge-shaped structure includes a bottom surface, a wedge surface and a light incident surface of wedge-shaped structure. The light source structure includes a light source, light emitted by which enters the light guide plate through the light incident surface of body structure and the light incident surface of wedge-shaped structure. In a direction perpendicular to the bottom surface, a ratio of thickness of the body structure to thickness of light-exiting surface of the light source is less than or equal to 88%.
