  10. The electronic device of one of claims 1 to 9, further comprising: a display support sheet (1370, 2160) comprising a first portion (2162) disposed on a rear surface of the flexible display (1310) and a second portion (2165) extending from the first portion (2162) but at least partially bent toward a front surface of the flexible display (1310), which is an opposite surface of the rear surface; wherein at least a portion of the second portion (2165) of the display support sheet (1370, 2160) is fixed to at least a portion of the support plate (1340).
  11. The electronic device of claim 10, wherein a length of the second portion (2165) of the display support sheet (1370, 2160) is formed to be longer than a thickness of the flexible display (1310).

Description

[Technical Field] The invention relates to a flexible electronic device. [Background Art] Electronic devices are gradually becoming slimmer, and improvements are being made to increase the rigidity, strengthen their design aspects, and differentiate their functional elements. Electronic devices are moving away from a uniform rectangular shape and are gradually being transformed into various shapes. Electronic devices may may have a deformable structure that is convenient to carry and allows for the use of a large screen display. Electronic devices may have a structure (e.g., a rollable structure or a slidable structure) that allows the display area of a flexible display (e.g., a rollable display) to be varied through the support of housings that slide relative to each other. Electronic devices with flexible displays are disclosed in US 2023 / 007796 A1 and US 2022 / 232716 A1. The above information is presented as background information only to assist in an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure. [Disclosure of Invention] [Technical Problem] The electronic device includes a rollable electronic device (e.g., a slidable electronic device), in which the display area of the flexible display (e.g., a rollable display) can be expanded and/or reduced depending on the operating state. The rollable electronic device according to an embodiment includes a first housing (e.g., a first housing part, a frame cover) and a second housing (e.g., a second housing part, a front cover) that are movably coupled relative to each other in a manner that is at least partially fitted together. For example, the first housing and the second housing may be slidably operable relative to each other and may support at least a portion of a flexible display (e.g., a rollable display, an expandable display, or a stretchable display). The flexible display (e.g., the rollable display) may, in a slide-in state, be induced to have a first display area (e.g., a screen reduction) and, in a slide-out state, be induced to have a second display area (e.g., a screen enlargement) that is larger than the first display area. The flexible electronic device (e.g., the rollable electronic device) may be subject to frequent slide-in and slide-out. The slide-in and slide-out of the flexible electronic device (e.g., the rollable electronic device) may cause the end (e.g., the longitudinal edge) of the flexible display (e.g., the rollable display) to be lifting -gaped. Various embodiments of the present disclosure may provide a flexible electronic device (e.g., a rollable electronic device) capable of preventing a lifting from occurring at an end (e.g., a longitudinal edge) of the flexible display (e.g., a rollable display). An electronic device according to claim 1 is provided according to the invention. Embodiments of the invention are presented in the dependent claims. An electronic device according to an embodiment of the present disclosure includes: a housing including a first housing part and a second housing part slidably disposed with respect to the first housing part; a flexible display at least a portion of which can slide into an inner side of the housing or slide out of an inner side of the housing according to sliding of the second housing part; a support bar at least a portion of which supports an edge portion of the flexible display on an inner side of the housing; and a plate the first portion of which is coupled to the support bar and the second portion of which is coupled to at least a portion of the edge portion of the flexible display. An electronic device according to an embodiment of the present disclosure includes: a housing including a first housing part and a second housing part slidably disposed with respect to the first housing part; a flexible display at least a portion of which can slide into an inner side of the housing or slide out of an inner side of the housing according to sliding of the second housing part; a support bar at least a portion of which supports the rear surface of an edge portion of the flexible display on an inner side of the housing; and a plate at least a portion of which is coupled to at least a portion of a front surface, which is opposite to the rear surface, of the edge portion of the flexible display. An electronic device according to an embodiment of the present disclosure includes: a housing including a first housing part and a second housing part slidably disposed with respect to the first housing part; a flexible display at least a portion of which can slide into an inner side of the housing or slide out of an inner side of the housing according to sliding of the second part; a display support sheet including a first portion disposed on a rear surface of the flexible display and a second portion extending from the first portion but bending tow
