1. A display device, comprising:
a display module comprising a display area, a transition area and a non-display area, wherein the display area surrounds the non-display area, and the transition area is located between the display area and the non-display area;
a backlight module arranged on a side of the display module away from a display side; wherein the backlight module comprises a backplane arranged on a side of the backlight module away from the display module, and a through hole located in the non-display area and used to accommodate an optical module;
a light-shielding glue located between the display module and the backlight module, wherein an orthographic projection of the light-shielding glue on the display module overlaps with the transition area;
a glue frame located between the light-shielding glue and the backplane, wherein an orthographic projection of the glue frame on the display module and an orthographic projection of the backplane on the display module overlap in a part of the transition area, and the orthographic projection of the glue frame on the display module and an orthographic projection of the through hole on the display module overlap at most partially;
wherein the backplane comprises a base and a bending portion, the base is arranged parallel to the display module, the bending portion surrounds the through hole in a space between a surface on a side of the base away from the display module and a surface on a side of the display module facing the base;
a joint cross section of the glue frame and the bending portion is a rectangle on a cross section perpendicular to a diameter of the through hole; or
the joint cross section of the glue frame and the bending portion is approximately a right-angled trapezoid on the cross section perpendicular to the diameter of the through hole, a side of the joint cross section of the glue frame and the bending portion adjacent to the through hole extends obliquely toward the through hole, and a right angle of the right-angled trapezoid adjacent to the display module is missed to form a step; or
the joint cross section of the glue frame and the bending portion is approximately a parallelogram on the cross section perpendicular to the diameter of the through hole.
