Abstract
The present disclosure provides a light guide plate-positioning column, a backlight module and a display apparatus. The column comprises a first positioning body for positioning a light guide plate and a second positioning body for positioning an optical film; the second positioning body is located on a side of the first and fixedly connected to it; a projection of the first positioning body in a direction from it toward the second completely covers that of the second, and a projection area of the first positioning body is greater than that of the second; wherein in the direction, a surface on a side of the first positioning body close to the second does not extend beyond a surface on a side of the plate close to the second. Both the requirements of the positioning strength of the plate and the fine positioning of the film can be met.
