A light guide plate is provided, including a body. A protruding portion that protrudes outwardly is provided on a lateral surface of the body, and the body is further provided with a slot. The slot is capable of enabling the protruding portion to be deformed elastically to position and fix the body. A backlight source and a display device are further provided.

First claim

Opening claim text (preview).

What is claimed is: 1. A light guide plate, comprising a body and a first protrusion, wherein the first protrusion is provided on a lateral surface of the body and protrudes outwardly; a protruding portion is provided on a lateral surface of the first protrusion and protrudes outwardly; a slot is provided in the first protrusion at a position corresponding to the protruding portion; the first protrusion and the protruding portion are deformable; and the slot is of a stripe shape and has a length larger than that of the protruding portion. 2. The light guide plate according to claim 1 , wherein an external lateral surface of the protruding portion is a slope. 3. The light guide plate according to claim 1 , wherein an external lateral surface of the protruding portion comprises a connection surface that extends downwardly from a top surface of the body and a slope in connection with the connection surface. 4. The light guide plate according to claim 1 , wherein an external lateral surface of the protruding portion is a cambered surface. 5. The light guide plate according to claim 1 , wherein an external lateral surface of the protruding portion comprises a connection surface that extends downwardly from a top surface of the body and a cambered surface in connection with the connection surface. 6. The light guide plate according to claim 1 , wherein a second protrusion is arranged on an external lateral surface of the protruding portion, and a transition surface between an external lateral surface and a bottom surface of the second protrusion is a slope or a cambered surface. 7. The light guide plate according to claim 6 , wherein a height of the second protrusion is smaller than a height of the protruding portion. 8. The light guide plate according to claim 1 , wherein the slot comprises a plurality of parallel sub-slots. 9. A backlight source, comprising the light guide plate according to claim 1 . 10. The backlight source according to claim 9 , wherein the light guide plate is positioned and fixed through interference fit between the protruding portion of the light guide plate and a backboard of a display device, or through interference fit between the protruding portion of the light guide plate and a frame surrounding the backlight source. 11. A display device, comprising a display panel, a backboard, a frame and the backlight source according to claim 9 , wherein the backlight source is arranged in a space surrounded by the backboard and the frame. 12. The display device according to claim 11 , wherein the body is positioned and fixed through interference fit between the protruding portion on the body and the backboard. 13. The display device according to claim 11 , wherein the body is positioned and fixed through interference fit between the protruding portion on the body and the frame.
