A display device, comprising:
- an electrically driving substrate;
- a display medium layer disposed on the electrically driving substrate, wherein the display medium layer comprises an electrophoretic display film or an electrowetting display film;
- a glue layer disposed around the display medium layer, the glue layer comprising a flat portion and a bent portion, wherein the flat portion connects to the display medium layer and extends outwardly from a periphery of the display medium layer by a distance, a top surface of the flat portion is flush with a top of the display medium layer, wherein in a cross-sectional view along a thickness direction of the display medium, a cross-sectional area of the flat portion is greater than a cross-sectional area of the bent portion, and the bent portion connects the flat portion and the electrically driving substrate;
- and
- a protective layer covering the display medium layer and the glue layer, wherein the glue layer fills a gap between the protective layer and the electrically driving substrate, and the protective layer is bent toward the electrically driving substrate along the glue layer, such that the display medium layer and the glue layer are completely wrapped between the electrically driving substrate and the protective layer.
