A light guide plate (100), a backlight module and a display. The light guide plate (100) is used in the backlight module, and comprises a plate body (20) and two oppositely arranged retaining walls (40). The plate body (20) comprises two oppositely arranged first sides (21) and two second sides (22) connected between the two first sides (21), wherein the two first sides (21) are non-light-incident sides of the light guide plate (100). The two retaining walls (40) are respectively arranged on the two first sides (21) in a protrusive manner. Each retaining wall (40) comprises a supporting step (41) and an abutment step (43) in a reverse direction of the supporting step (41). The supporting step (41) is arranged on the side of the retaining wall (40) facing the plate body (20). The side of the retaining wall (40) facing away from the plate body (20) extends to form the abutment step (43). The supporting step (41) is used for supporting and positioning a liquid crystal panel installed on the backlight module. The abutment step (43) is used for positioning the light guide plate (100) and a back plate (80) of the backlight module. The second sides (22) are used as light-incident sides of the light guide plate (100) for contact with a light source. |
