1. A display device, comprising:
a casing; and
an OLED module supported by the casing and including a plurality of layers including an OLED layer, the plurality of layers being stacked on top of another through an adhesive,
wherein the casing includes a coupling portion coupling together, on a coupling surface provided across from a support surface supporting the OLED module, a bending region of the casing and at least one end region of the casing, the coupling portion including one or more coupling portions, the coupling surface and the support surface being included in a surface of the casing, and the bending region including one or more bending regions for folding a display surface of the OLED module into a valley shape, and
when the display surface is folded into a valley shape in a first direction, the coupling portion pulls the at least one end region of the casing in a second direction for folding the display surface into a mountain shape, the second direction being opposite to the first direction.
