In an embodiment, the display261may be visually exposed to the outside of the electronic device201through a display area2610. In an embodiment, the display area2610may include a first area261A provided parallel to the first surface210A and the third surface220A, a second area261B connected to one end of the first area261A, and a third area261C connected to the other end of the first area261A. The second area261B and the third area261C may be provided on opposite sides based on the first area261A. In an embodiment, each of the second area261B and the third area261C may form a flexibly curved surface. The display261may display a screen through the display area2610. The display261may display one connected screen through the whole display area2610and may display a screen through a portion of the display area2610. In an embodiment, the display261may display a plurality of screens partially divided through the display area2610. In an example, the display261may display one screen through the first area261A and may display another screen, which is different from the screen displayed through the first area261A, through the second area261B and/or the third area261C.

The display261may include a flat portion2611forming at least a portion of the display area2610and a rolling portion2612extending from the flat portion2611. The rolling portion2612may be withdrawn from the inside to the outside of the electronic device201or may be inserted from the outside to the inside of the electronic device201according to the movement of the first housing210relative to the second housing220. The rolling portion2612that is withdrawn to the outside of the electronic device201may be visually exposed to the outside of the electronic device201and may form the display area2610with the flat portion2611. The area of the display area2610may change according to the degree of withdrawal of the rolling portion2612.

According to an embodiment, the area of the display area2610(e.g., the first area261A, the second area261B, and the third area261C) of the display261may change according to a change in a state of the electronic device201. In an embodiment, the display area2610of the display261may form a first area (e.g., a minimum area) reduced to the minimum in the first state (e.g., the reduced state or the shape ofFIG.2A) of the electronic device201and may form a second area (e.g., a maximum area) extended to the maximum in the second state (e.g., the extended state or the shape ofFIG.2C) of the electronic device201. The first housing210and the second housing220may switch a state between the extended state and the reduced state. For example, the extended state refers to a maximally slid-out state of the first housing210from the second housing220. The reduced state refers to a maximally slid-in state of the first housing210to the inside of the second housing220. When the electronic device201is between the first state and the second state, the display261may expand or reduce the area of the display area2610, corresponding to the state of the electronic device201. For example, while changing from the first state to the second state, when the first housing210moves relative to the second housing220in the first moving direction (direction {circle around (1)}) by a certain length d, the length of the display area2610that is parallel to the first moving direction (direction {circle around (1)}) changes to a second length d2 increasing by the certain length d from a first length d1 such that the display area2610may be extended. While changing from the second state to the first state, when the first housing210moves relative to the second housing220in the second moving direction (direction {circle around (2)}) by the certain length d, the length of the display area2610that is parallel to the second moving direction (direction {circle around (2)}) changes to the first length d1 decreasing by the certain length d from the second length d2 such that the display area2610may be reduced. While the electronic device201changes the state between the first state and the second state, the size of the second area261B and the size of the third area261C may be substantially constant.

According to another embodiment, the electronic device201may include at least one of an input module (e.g., the input module150ofFIG.1), a sound output module (e.g., the sound output module155ofFIG.1), a camera module280(e.g., the camera module180ofFIG.1), or a connector port208.

In yet another embodiment, the input module may receive an input signal according to the manipulation of a user. The input module may be, for example, on the seventh side surface220E or the eighth side surface220F of the second housing220. It should be noted that positions in which the input module is are not limited thereto. For example, the input module may also be in the first housing210.

At least one housing between the first housing210and the second housing220may include a hole for radiating sound generated by the sound output module to the outside. For example, the first housing210may include a first hole H1 that is covered by the second housing220when the electronic device201is in the first state and that is exposed to the outside when the electronic device201is in the second state. For example, the second housing220may include a second hole H2 formed in at least one of the sixth side surface220D, the seventh side surface220E, or the eighth side surface220F. In another example, the first hole H1 and the second hole H2 may be substantially aligned with each other when the electronic device201is in the first state.
