1. A display assembly, comprising:
a flexible display panel, including:
a main portion with a display surface; and
a bending portion bent toward a surface of the main portion facing away from the display surface; wherein the bending portion includes: a first straight sub-portion, an arched sub-portion, and a second straight sub-portion that are sequentially connected in an extending direction of the bending portion; the first straight sub-portion is further connected to the main portion, and the second straight sub-portion is located at the surface of the main portion facing away from the display surface;
a cover plate disposed above the main portion and the first straight sub-portion;
a first support layer located between the first straight sub-portion and the second straight sub-portion along a thickness direction of the display assembly, and between the main portion and the second straight sub-portion along the thickness direction of the display assembly, the first support layer being connected to the second straight sub-portion;
a second support layer disposed between the first straight sub-portion and the cover plate; an orthogonal projection of the second support layer on the cover plate overlapping with an orthogonal projection of the first support layer on the cover plate, and the second support layer being configured to support the first straight sub-portion;
a first backfilm disposed on surfaces of the main portion and the first straight sub-portion facing the first support layer; and
a second backfilm disposed on a surface of the second straight sub-portion facing the first support layer, the first backfilm being closer to the arched sub-portion than the second backfilm in a direction from the first support layer to the arched sub-portion.
