Abstract

The present disclosure provides a display module, including: a flexible display panel, including: a first straight portion; a second straight portion, located on a back side of a light exiting surface of the first straight portion; and a bending portion, connected to the first straight portion and the second straight portion, wherein an inner curved surface includes a bending start point and a bending end point, a spacing between the bending start point and the bending end point is D1, a spacing from a midpoint of a connecting line between the bending start point and the bending end point to an inner curved surface peak of the inner curved surface is D2, and D1 and D2 satisfy a formula as follows: D2<(D1)/2.
