Electronic device with movable flexible display and operating method thereof

An electronic device comprising:

• a housing comprising:
• a first plate,
• a first sidewall extending from one end of the first plate toward a front of the electronic device,
• a second sidewall extending from an opposite end of the first plate toward the front of the electronic device, and
• an inner structure coupled with the first sidewall or the second sidewall, and being spaced apart from the first plate;
• a flexible display movably assembled to the housing, and comprising a planar portion disposed on the inner structure and a bendable portion extending from the planar portion along a vicinity of the second sidewall;
• a flexible plate disposed along a rear face of the bendable portion;
• and
• at least one electronic component disposed between the first plate and the flexible plate,
• wherein, when the planar portion moves in a first direction, the electronic device is in a first state where an one portion of the bendable portion is led into the housing,
• wherein, when the planar portion moves in a second direction opposite to the first direction, the electronic device is in a second state where the one portion of the bendable portion is led out from the housing, and
• wherein at least part of the at least one electronic component is aligned with an opening formed in the flexible plate and a concave portion formed in the flexible display when the electronic device is in the second state such that the at least part of the at least one electronic component is viewable from an outside through the opening and the concave portion.
