Disclosed is an electronic device comprising: a display, a sensor configured to detect geometric deformation of the electronic device, at least one processor, and a memory operatively connected to the at least one processor and storing at least one application. The memory may include one or more instructions which, when executed, cause the at least one processor to: control the display to display an execution screen of the at least one application on the display in response to execution of the at least one application in the memory; check a rotation mode setting of the electronic device; obtain display characteristic information of the display in response to a geometric deformation event detected by the sensor; determine a display mode of the execution screen based on the display characteristic information and the checked rotation mode setting and map same to the at least one application; and control the display to display the execution screen on the display based on the mapped display mode.
