## Abstract

According to various embodiments, an electronic device may comprise a housing comprising a first housing and a second housing. The first housing may comprise: a hinge module; a first plate connected to the hinge module; a second plate facing away from the first plate; and a first side frame surrounding a first space between the first plate and the second plate. The second housing may comprise: a third plate connected to the hinge module; a fourth plate facing away from the third plate; and a second side frame surrounding a second space between the third plate and the fourth plate. The first housing and the second housing may fold or unfold with regard to each other with reference to the hinge module. In addition, the electronic device may comprise: a printed circuit board disposed in the second space; a first display disposed to be supported by the first plate and the third plate; a battery disposed between the third plate and the fourth plate in the second space; and a second display disposed between the battery and the fourth plate to be visible from the outside through at least a part of the fourth plate. At least a part of the second display may be disposed to face the battery.

## Claims

### Claim 1

An electronic device comprising:
