1. A display device, comprising a display assembly, a middle frame assembly, a bezel member, a glue structure and a backplane; wherein
the middle frame assembly is located on a light incident side of the display assembly; at an edge of the display assembly, the middle frame assembly provides support for the display assembly in a thickness direction of the display assembly, and the middle frame assembly is connected to the display assembly by means of the glue structure in the thickness direction of the display assembly; and in the thickness direction of the display assembly, a distance from the middle frame assembly to the display assembly is greater than 0;
the backplane is located on a side of the middle frame assembly away from the display assembly; and
the bezel member is located on a periphery of the display assembly and a periphery of the middle frame assembly, and is detachably connected to the middle frame assembly;
further comprising a light source assembly located between the backplane and the display assembly, wherein light emitted by the light source assembly is emitted out of the display device through the display assembly;
the middle frame assembly and the backplane constitute a light propagation space;
the middle frame assembly comprises a support surface; the support surface is an area where the middle frame assembly contacts with the glue structure, and the glue structure is transparent glue; the display assembly comprises a display panel and an optical film material located on a light incident side of the display panel; and an orthographic projection of the support surface on the display panel is located in a non-display area of the display panel; and
the middle frame assembly further comprises an exposed surface facing the light propagation space and not covered by the glue structure;
wherein the middle frame assembly further comprises a transparent member, and the middle frame assembly is in contact with the glue structure through a first wrapping portion of the transparent member;
wherein the middle frame assembly comprises a support portion and a fixing portion; the support surface is located on a side of the support portion close to the display assembly; the exposed surface is located on the support portion; and the fixing portion is located on a side of the support portion away from the display assembly; and
the backplane comprises a backplane body extending in the same direction as the display assembly, and a backplane flange located at an edge of the backplane body and extending toward the display assembly; the backplane flange is bent to form a platform portion located between the backplane body and the middle frame assembly; and the fixing portion is provided in abutment with the platform portion.
