According to various embodiments of the present invention, disclosed is a display comprising: a first region which is an active region; at least one second region which is arranged side-by-side with the first region and can expand from the first region; a first deformation measurement sensor which is located in the second region and formed in a zigzag form in a first direction that is the expansion direction of the second region; and a second deformation measurement sensor which is located in the second region so as to be spaced apart from the first deformation measurement sensor, and is formed in a zigzag form in the first direction. The first deformation measurement sensor includes: a plurality of first resistance regions that gradually decrease in length from one side to the other side of the second region in a second direction different from the first direction; and a plurality of connection regions for connecting the plurality of first resistance regions. The second deformation measurement sensor includes: a plurality of second resistance regions that gradually increase in length from the one side to the other side of the second region; and a plurality of second connection regions for connecting the plurality of second resistance regions.
