Abstract: Provided are a shape-variable electronic device and an operation method of the same. More specifically, the shape-variable electronic device includes a substrate having a cell region, a light source on the cell region, a flexible layer provided vertically spaced apart from the light source part, a chamber between the light source part and the flexible layer, and a pressure control unit configured to adjust an internal pressure of the chamber. The flexible layer includes a photo-thermal response part configured to emit thermal energy by receiving light emitted from the light source part, and a deformation part of which mechanical stiffness is decreased by receiving the thermal energy from the photo-thermal response part.
