An electronic device includes a display module including a folding display unit which extends in a first direction and be foldable with reference to a folding axis and a first non-folding display unit and a second non-folding display unit which are spaced apart from each other with the folding display unit therebetween; a support member disposed below the display module, and including a folding part having a plurality of patterns defined therein and corresponding to the folding display unit and a first non-folding part and a second non-folding part respectively corresponding to the first non-folding display unit and the second non-folding display unit; and an adhesive layer disposed between the display module and the support member. The adhesive layer has a modulus of about 1 megapascal (MPa) to about 1500 MPa at −20 degrees Celsius) (° C.).
