A display assembly includes a flexible display panel, a cover plate, and first and second support layers. The panel includes a main portion with display surface, and a bending portion. The bending portion includes a first straight sub-portion connected to the main portion, an arched sub-portion, and a second straight sub-portion located at a surface of the main portion facing away from the display surface. The cover plate is disposed above the main portion and the first straight sub-portion. The first support layer is located between the first and second straight sub-portions, between the main portion and the second straight sub-portion, and connected to the second straight sub-portion. The second support layer is disposed between the first straight sub-portion and the cover plate, and configured to support the first straight sub-portion. An orthogonal projection of the second support layer overlaps with an orthogonal projection of the first support layer.
