Electronic device and method of manufacturing the same

A method of manufacturing an electronic device, the method comprising:

• preparing a display module including a deformation part which is foldable, rollable, or slidable and a non-deformation part next to the deformation part;
• forming a preliminary window member including a synthetic resin film, a first preliminary adhesive layer, and a second adhesive layer;
• providing the preliminary window member onto the display module;
• and
• forming a window member including the synthetic resin film, a first adhesive layer, and the second adhesive layer by radiating second light to the preliminary window member,
• wherein the forming the preliminary window member includes:
• preparing a substrate;
• providing a post-curable adhesive and a low hardness adhesive having a hardness smaller than a hardness of the post-curable adhesive onto the substrate;
• providing the synthetic resin film onto the post-curable adhesive and the low hardness adhesive;
• and
• forming the first preliminary adhesive layer and the second adhesive layer by radiating first light to the post-curable adhesive and the low hardness adhesive,
• wherein the first adhesive layer includes the post-curable adhesive and has a Young's modulus of 0.1 megapascal to 1 megapascal at a room temperature, and
• wherein the second adhesive layer includes the low hardness adhesive.
