Abstract

A display module is provided that includes a curved back panel including a bottom board and a side frame disposed on the bottom board; a display assembly located in an accommodation space enclosed by the side frame and the bottom board; a cover board located on a side, away from the bottom board, of the display assembly and supported by the side frame; and a bonding layer including a first bonding portion and a second bonding portion, which are located between the cover board and the side frame. Both the first bonding portion and the second bonding portion are configured to bond the cover board to the side frame to enable the cover board to be curved. The second bonding portion has a smaller elasticity modulus than the first bonding portion. A method for manufacturing the display module, and a display apparatus are further provided.
