Abstract

A display module includes a back plate, a light guide plate, a rubber frame and a display panel, the light guide plate is fixed on a bearing surface, a connecting line between two end portions of the bearing surface forms a first curve. The first curve includes a circular arc segment and a transition curve segment, and bends in a direction away from the display panel; the circular arc segment is located at the middle, at least one end of the circular arc segment is provided with the transition curve segment; the transition curve segment is located at a first position, the first position being a position of the bearing surface opposite to a second position, the second position being a position where light leaks from the display panel, the radius of curvature of the transition curve increases along a direction close to an end portion of the first curve.
