Description

Electronic device including tension maintenance structure Various embodiments of the present invention relate to an electronic device having a tension-maintaining structure. Electronic devices are becoming increasingly slimmer and are being improved to increase rigidity, enhance design aspects, and differentiate their functional elements. Electronic devices are moving away from uniform rectangular shapes and are gradually transforming into various shapes. Electronic devices can have deformable structures that allow for convenient portability and the use of large-screen displays. For example, as part of a deformable structure, an electronic device can have a structure that can expand the display area through a flexible display that operates in a sliding manner (e.g., a rollable structure).
