Abstract
The present disclosure provides a backlight module and display apparatus. The backlight module includes: a back plate; a light guide plate provided on the back plate, at least one side of the light guide plate being provided with at least one first concave-convex structure; and at least one position-limiting component provided on the back plate, the position-limiting component comprising at least one second concave-convex structure, the at least one second concave-convex structure and the at least one first concave-convex structure being cooperated with each other and being rotatable with respect to each other within a plane where the light guide plate is located, such that a contact state between the cooperated first and second concave-convex structures is switchable between an abutting contact state and an intermeshing state.
