1. A display module, comprising:
a curved back panel comprising 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 of the display assembly away from the bottom board and supported by the side frame; and
a bonding layer comprising a first bonding portion and a second bonding portion located between the cover board and the side frame,
wherein the first bonding portion and the second bonding portion are both configured to bond the cover board to the side frame to enable the cover board to be curved, and
wherein an elasticity modulus of the second bonding portion is smaller than the elasticity modulus of the first bonding portion.
