2 . The display device according to claim 1 , wherein at least a portion of the support surface extends in the same direction as the display panel in a support region thereof.

3 . The display device according to claim 1 , wherein the support surface comprises a first curved surface gradually approaching the display assembly in the thickness direction of the display assembly and gradually approaching an outer contour of the display device.

4 . The display device according to claim 3 , wherein the exposed surface and the first curved surface are of a continuous structure, and the exposed surface and the first curved surface form a second curved surface;
a first included angle between a tangent plane at an end of the second curved surface close to a backplane body and a plane where the display panel is located is not less than 90 degrees and not more than 105 degrees; a second included angle between a tangent plane at an end of the second curved surface away from the backplane body and the plane where the display panel is located is not less than 27 degrees and not more than 33 degrees; and wherein both the first included angle and the second included angle face the light propagation space.

5 . The display device according to claim 1 , wherein an end of the support surface close to the bezel member and facing the glue structure has a fillet having a diameter of not less than 0.13 mm and not more than 0.17 mm.

6 . The display device according to claim 1 , wherein
on at least one side of the display device, a ratio of a width of the glue structure extending from the bezel member to an interior of the display device to a minimum thickness of the glue structure is not less than 1:3 and not more than 1.3:3; and a width of the glue structure in a direction parallel to the backplane is not less than 0.6 mm and not more than 0.9 mm, and the minimum thickness of the glue structure is not less than 0.2 mm and not more than 0.3 mm.

7 . The display device according to claim 1 , wherein a thickness of the first wrapping portion of the transparent member is not less than 1 mm and not more than 2 mm.

8 . The display device according to claim 1 , wherein the support portion comprises a support body and the transparent member; the transparent member wraps the support body on the support surface and the exposed surface, and the transparent member wraps at least a portion of an area of the support body on a side of the support body close to the bezel member; and
a portion of the transparent member wrapping the support surface and the exposed surface is provided as a smooth surface, and a contact surface between the transparent member and the bezel member is provided as a frosted surface.

9 . The display device according to claim 1 , wherein the display device further comprises a light shielding structure provided at least between the bezel member and a non-display area of the display assembly.

10 . The display device according to claim 9 , wherein the light shielding structure comprises a light shielding glue structure provided between the bezel member and the non-display area of the display assembly;
