     BACKGROUND 
     Field 
     An embodiment relates to an electronic device including a protective cover for protecting a flexible display. 
     Description of Related Art 
     Electronic devices are slimmed down and enhanced to differentiate functional elements while reinforcing their design aspects. Electronic devices are evolving to have various shapes as well as their stereotypical rectangular shape. Electronic devices may have a transformable structure that allows for use of a larger display and ease to carry. In an example transformable structure, an electronic device may have a structure (e.g., a rollable structure or a slidable structure) capable of changing the display area of the flexible display through support by housings that are slidable on each other. A rollable electronic device (or a slidable electronic device) may be configured to allow the flexible display (or rollable display) to be rolled up or unrolled. A slidable electronic device may be configured such that the flexible display is slid to enlarge or shrink the screen. 
     SUMMARY 
     In an electronic device having a rollable display, the rollable display may include a plurality of layers. When the rollable display is pulled in/out, a slip occurs between the plurality of layers, causing a side of the rollable display to be lifted. Further, an extension, which extends from a side of the flexible display and bends at about 180 degrees to connect to the flexible printed circuit board disposed on the rear surface of the flexible display, is vulnerable to external impact. 
     Various example embodiments provide an electronic device capable of protecting the edge of the rollable display, which is vulnerable to external impact, and preventing or reducing the likelihood of a peel-off at the edge. 
     According to an embodiment, an electronic device may comprise a first housing including an antenna provided on a side surface thereof, a second housing provided to slide in a first direction to be at least partially drawn out of the first housing and to slide in a direction opposite to the first direction to be drawn into the first housing, a flexible display including a first side including a fixed portion and a second side provided to be drawn out of an inside of the first housing and/or drawn into the inside of the first housing based on at least an operation of the second housing, and a protective cover provided between at least the fixed portion and the first housing to contact at least a portion of an upper portion of the fixed portion. A first space may be provided between at least the protective cover and a side portion of the fixed portion. 
     According to various example embodiments, the protective cover provided in the electronic device may protect the extension provided in the fixed portion (or edge portion) of the rollable display from external impact and prevent or reduce the likelihood of the edge portion from being lifted when the rollable display is pulled in/out.

For convenience of description, in the following description, the state of the flexible display  230  before draw-in or draw-out commences is denoted as a first state or an initial state, and the state of the flexible display  230  after draw-in or draw-out has been done is denoted as a second state or a switching state. During draw-in, the first state may be denoted as a first drawn-out state to indicate a state before the draw-in starts, and the second state may be denoted as a first drawn-in state to indicate a state after the draw-out has been done. In the draw-in, the first state may be denoted as a second drawn-in state to indicate a state before the draw-out starts, and the second state may be denoted as a second drawn-out state to indicate a state after the draw-out has been done. 
     According to an embodiment, a first area corresponding to at least a portion of the flexible display  230  supported by the bendable member (e.g., the bendable member  240  of FIG. 
       4 ) may be disposed not to be received in the first receiving portion  2101  of the first housing  210  or the second receiving portion  2201  of the second housing  220 . The first area of the flexible display  230  drawn out of the receiving portion (e.g., the first receiving portion  2101  or the second receiving portion  2201 ) may be disposed to be visible from the outside (e.g., front surface). The first area may include an edge portion (e.g., the edge portion  231 ) of the display. A second area corresponding to at least a portion of the flexible display  230  supported by the bendable member(e.g., the bendable member  240  of  FIG.  4   ) may be received in the first receiving portion  2101  of the first housing  210  or the second receiving portion  2201  of the second housing  220 .

In this case, the whole or part of the fourth side surface  2211  overlaps the first side surface  2111  and may thus be disposed to be substantially invisible from the outside. Further, the whole or part of the sixth side surface  2213  overlaps the third side surface  2113  and may thus be disposed to be substantially invisible from the outside. For example, the fourth side surface  2211  or the sixth side surface  2213  may be disposed to be at least partially visible from the outside in the closed state. 
     According to an embodiment, when drawn in, the second supporting member  222  included in the second side member  221  overlaps the first supporting member  212  included in the first side member  211  and may thus be disposed to be substantially invisible from the outside. For example, in a state not fully drawn in, a portion of the second supporting member  222  may overlap the first supporting member  212  to be invisible from the outside, and the rest of the second supporting member  222  may be disposed not to overlap the first supporting member  212  to be visible from the outside. 
     According to an embodiment, the electronic device may include a rear cover  213 .

The driving module  400  may be disposed in an inner space (e.g., the first receiving unit  2101  or the second receiving unit  2201 ). The driving module  400  may provide a driving force for moving the second housing  220  in a direction in which the second housing  220  is drawn out from the first housing  210  (direction {circle around (1)}) and/or in a direction in which the second housing  220  is drawn in (direction {circle around (2)}). The driving module  400  may be disposed in, e.g., the second housing  220  (e.g., the sliding frame  225 ). 
     According to an embodiment, the driving module  400  may include a driving motor  410 , a first gear  411  (e.g., a pinion gear) mounted on the driving motor  410 , and a second gear  421  (e.g., a rack gear) engaged with the first gear  411 . The driving motor  410  may move together with the sliding frame  225  when the electronic device  200  is drawn in and/or out. 
     According to an embodiment, the driving module  400  may be disposed in the sliding frame  225  and be positioned on the same plane as the sliding frame  225 . The driving module  400  may relatively reduce the thickness of the electronic device  200  to contribute to slimming down the electronic device  200 , as compared to when it is disposed above or under the sliding frame  225 . 
     According to an embodiment, in the electronic device  200 , as the driving motor  410  is driven, the second gear  421  linearly moves, inducing draw-in or draw-out. Specifically, the second gear  421  pushes a portion of the first housing  210  or an electronic component in the first receiving unit  2101  to move the sliding frame  225  in the direction {circle around (2)} (e.g., −x axis direction), so that the flexible display  230  may be drawn out. 
     According to an embodiment, the electronic device  200  further may include a protective cover  280  disposed between the first housing (e.g., the cover housing  214 ) and the flexible display  230  to protect the flexible display  230 . The protective cover  280  may be provided, e.g., between the second side surface  2112  of the cover housing  214  and the side surface  2153  of the bracket housing  215 . The protective cover  280  may protect the fixed portion (e.g., edge portion  231 ) of the flexible display  230  from external impact and be configured so that two opposite sides of the segmenter (e.g., the third segmenter  3211  or fourth segmenter  3212 ) provided on the side surface (e.g., the second side  2112 ) of the first housing  210  are not parted. The protective cover  280  may be integrally formed with the first housing  210  (e.g., the bracket housing  215 ). 
     According to an embodiment, a support sheet  270  may be attached to the rear surface of the flexible display  230 . The rear surface of the flexible display  230  may indicate a surface positioned opposite to a surface from which light is emitted from the display panel (e.g., the display panel  610  of  FIG.  6 A ) including a plurality of pixels. The support sheet  270  may contribute to durability of the flexible display  230 . The support sheet  270  may reduce the effect on the flexible display  230  by the load or stress that may occur when the flexible display  230  is drawn in/out. The support sheet  270  may prevent or reduce the likelihood of damage to the flexible display  230  by the force transferred when the sliding frame  225  is moved. 
     According to an embodiment, the support sheet  270  may be formed of various metal materials and/or non-metal materials (e.g., polymers). The support sheet  270  may include, e.g., stainless steel. The support sheet  270  may include, e.g., engineering plastic. The support sheet  270  may be implemented integrally with the flexible display  230 . 
     According to an embodiment, the support sheet  270  prevents or reduces the likelihood of the electronic components (e.g., the bendable member  240 ) positioned inside the electronic device  200  from being substantially visible from the outside through the flexible display  230 . 
     According to an embodiment, a touch panel or a pen recognition panel may be provided on the support sheet  270 . The touch panel may detect the user&#39;s finger gesture input and may output a touch event value corresponding to the detected touch signal. The touch panel may be implemented of either a capacitive type or a resistive type. The capacitive type is a scheme for calculating the touch coordinates by detecting micro electricity generated in the user&#39;s body. The resistive type is a type in which includes two electrode plates embedded in the touch panel to calculate the touch coordinates by detecting a current flow generated as the upper and lower plates of the touched point contact. The pen recognition panel may detect the user&#39;s pen gesture input according to the operation of the user&#39;s touch pen (e.g., stylus pen or digitizer pen) of the user and output a pen proximity event value or pen touch event value. The pen recognition panel may be implemented, e.g., in an EMR (Electro-Magnetic Resonance) type and may sense a touch or proximity input by a change in electromagnetic field due to the approach and/or touch of the touch pen. 
       FIG.  6 A  is a side view illustrating a flexible display in an electronic device in an open state according to an embodiment.  FIG.  6 B  is a side view illustrating a flexible display in an electronic device in a closed state according to an embodiment. 
     Referring to  FIGS.  6 A and  6 B , the flexible display  230  may include a plurality of layers stacked and attached, a fixed portion (e.g., edge portion  231 ) fixed by the first housing  210 , and/or an extension  232 . An adhesive member (not shown) may be disposed between the plurality of layers included in the flexible display  230  to adhere the layers to each other. According to an embodiment, the flexible display  230  may include a display panel  610 , a base film  620 , and/or a lower panel  630 . The display panel  610  may include a light emitting layer  611 , a thin film transistor (TFT) film  612 , and/or an encapsulation layer  613 . According to an embodiment, at least one additional polymer layer (e.g., a layer including PI, PET, or TPU) other than the base film  620  may be further disposed on the rear surface of the display panel  610 . The light emitting layer  611  may include a plurality of pixels implemented as light emitting elements, such as OLEDs or micro LEDs. The light emitting layer  611  may be disposed on the TFT film  612  through organic material evaporation. The TFT film  612  may be positioned between the light emitting layer  611  and the base film  620 . The TFT film  612  may refer to a structure in which at least one TFT is disposed on a flexible substrate (e.g., a PI film) through a series of processes, such as deposition, patterning, and etching. The at least one TFT may control the current to the light emitting element of the light emitting layer  611  to turn on or off the pixel or adjust the brightness of the pixel. The at least one TFT may be implemented as an amorphous silicon (a-Si) TFT, a liquid crystalline polymer (LCP) TFT, a low-temperature polycrystalline oxide (LTPO) TFT, or a low-temperature polycrystalline silicon (LTPS) TFT. The encapsulation layer (e.g., thin-film encapsulation (TFE))  613  may seal the light emitting layer  611  to prevent or reduce the likelihood of penetration of oxygen and/or moisture into the OLED. 
     According to an embodiment, the base film  620  may include a flexible film formed of a material, such as polyimide or polyester. The base film  620  may serve to support and protect the display panel  610 . The base film  620  may be referred to as a protective film, a back film, or a back plate. The base film  620  may be positioned between the display panel  610  and the lower panel  630 . 
     According to an embodiment, the lower panel  630  may include a plurality of layers for various functions. The lower panel  630  may include a light blocking layer  631 , a buffer layer  632 , or a lower layer  633 . For example, the light blocking layer  631 , the buffer layer  632 , or the lower layer  633  may be sequentially positioned in order from the base film  620 . The light blocking layer  631  may block light incident from the outside. For example, the light blocking layer  631  may include an embossed layer. The embossed layer may be a black layer including an uneven pattern. The buffer layer  632  may alleviate the external impact applied to the flexible display  230 . For example, the buffer layer  632  may include a sponge layer or a cushion layer. The lower layer  633  may diffuse, disperse, and/or radiate the heat generated in the electronic device  200  and/or the flexible display  230 . The lower layer  633  may absorb and/or shield electromagnetic waves. The lower layer  633  may mitigate the external impact applied to the electronic device  200  and/or the flexible display  230 . The lower layer  633  may include a composite sheet  633   a  or a copper sheet  633   b.  The composite sheet  633   a  may include at least one of polyimide or graphite. The composite sheet  633   a  may be replaced with a single sheet including one material (e.g., polyimide or graphite). The composite sheet  633   a  may be positioned between the buffer layer  632  and the copper sheet  633   b.  The lower layer  633  may include various other layers for various functions. 
     According to an embodiment, at least one of the plurality of layers (e.g., the light blocking layer  631 , the buffer layer  632 , the composite sheet  633   a,  and the copper sheet  633   b ) included in the lower panel  630  may be omitted. According to various embodiments, the arrangement order of the plurality of layers included in the lower panel  630  is not limited to the embodiment of  FIG.  6 B , and various changes may be made thereto. 
     According to an embodiment, at least some of the plurality of layers included in the lower layer  633  may include an opening formed corresponding to a sensor (e.g., a fingerprint sensor) positioned inside the electronic device  200 . The sensor may overlap the opening or may be at least partially inserted into the space of the opening. 
     According to an embodiment, the extension  232  extends from the fixing portion (e.g., the edge portion  231 ) and is bent with a predetermined curvature, electrically connecting the display driving chip (DDI) (display driver IC) with the flexible printed circuit board (FPCB) (not shown) positioned on the rear surface of the flexible display  230 . The display driving chip may be provided on the extension  232 , for example. 
     The extension  232  may be provided by, e.g., one of a chip-on-film (COF) scheme or a chip-on-plastic (COP) scheme, but is not limited thereto. 
     The chip-on-film scheme is a scheme in which the display driving chip is mounted on a film substrate that connects a display glass substrate and a flexible printed circuit board. When the extension  232  is provided by a chip-on-film scheme, the extension  232  may be electrically connected to the flexible printed circuit board based on anisotropic conductive film (ACF) bonding. The ACF may be an anisotropic conductive film formed by mixing fine conductive particles (e.g., nickel, carbon, or solder balls) with an adhesive resin (e.g., thermosetting resin) to allow current to flow only in one direction. If the ACF is disposed between the extension  232  and the flexible printed circuit board (not shown) positioned on the rear surface of the flexible display  230  and is then compressed by heat and pressure, the conductive pattern (not shown) formed on the extension  232  may be electrically connected to the conductive pattern formed on the flexible printed circuit board. In this case, the adhesive resin may bond the extension  232  and the flexible printed circuit board. The electrical paths included in the extension  232  may electrically connect at least one layer (e.g., TFT film) and the flexible printed circuit board. For example, the electrical paths may be formed on the TFT film  612  based on LTPS, LTPO, or a-Si together with the TFT. 
     The chip-on-plastic scheme is a scheme for mounting a display driving chip on a flexible polyimide (PI) substrate used as a display substrate. When the extension  232  is provided by a chip-on-plastic scheme, the extension  232  may be formed to extend from the base film  620 . 
     According to an embodiment, each of the layers of the flexible display  230  may slip from its adjacent layers when the flexible display  230  is drawn in and/or out. Specifically, as the flexible display  230  rolls, the layer positioned higher may further slip from the fixed portion (e.g., edge portion  231 ) to the flat portion (e.g., the first area  230   a  of  FIG.  2 A ) (e.g., direction {circle around (3)}). As the layers are misaligned at the fixed portion (e.g., edge portion  231 ) due to the slip between the plurality of layers as shown in  FIG.  6 B , the fixed portion (e.g., edge portion  231 ) may be bent in the opposite direction (e.g., direction {circle around (4)}) from the bent direction, causing a peel-off. When a peel-off occurs at the fixed portion (e.g., edge portion  231 ), the extension  232  may contact its surrounding first housing (e.g., the bracket housing  215  of  FIG.  4    or the cover housing  214  of  FIG.  4   ), thus damaging the extension  232 . Or, as a peel-off occurs at the fixed portion (e.g., edge portion  231 ), the spacing between the flexible display  230  and the antenna (e.g., the second antenna A 2  of  FIG.  2 A ) disposed on the side surface (e.g., the second side surface  2112  of  FIG.  2 A ) of the first housing  210  (e.g., the cover housing  214  of  FIG.  4   ) is narrowed, deteriorating the communication performance of the antenna (e.g., the second antenna A 2  of  FIG.  2 A ). According to various embodiments, the electronic device  200  is provided with the protective cover  280  to be described below in detail, thereby preventing or reducing the likelihood of a peel-off at the fixed portion (e.g., edge portion  231 ) and maintaining the spacing between the antenna (e.g., the second antenna A 2  in  FIG.  2 A ) and the fixed portion (e.g., edge portion  231 ) regardless of draw-in or draw-out while preventing or reducing damage to the extension  232 . 
       FIG.  7    is an enlarged cross-sectional view illustrating a protective cover and its surrounding components in an electronic device according to an embodiment. 
     Referring to  FIG.  7   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230 , or the protective cover  280  may be identical in whole or part to the configuration of the first housing  210 , the second housing  220 , the flexible display  230 , and the protective cover  280  of  FIGS.  2  to  4   . 
     According to an embodiment, the protective cover  280  may include a first portion  281 , a second portion  282 , and/or a curved portion  283 . A portion of the first portion  281  of the protective cover  280  may contact the flexible display  230 . The second portion  282  of the protective cover  280  may contact the first housing  210  (e.g., the bracket housing  215 ). The first portion  281  and the outer surface of the curved portion  283  of the protective cover  280  may contact a side surface (e.g., the second side surface  2112 ) of the first housing  210  (e.g., the cover housing  214 ). 
     According to an embodiment, the protective cover  280  may be provided between the first housing  210  and the flexible display  230 . The protective cover  280  may be disposed such that a portion thereof contacts at least a portion of the upper portion  2311  of the edge portion  231 . Specifically, the protective cover  280  may be disposed such that a portion of the first portion  281  contacts at least a portion of the upper portion  2311  of the edge portion  231 . As a portion of the upper portion  2311  of the edge portion  231  contacts the protective cover  280 , it is possible to prevent or reducing a peel-off at the edge portion  231  caused when the flexible display  230  is drawn in/out. 
     According to an embodiment, the protective cover  280  and a portion of the upper portion  2311  of the edge portion  231  are not attached to each other, and the protective cover  280  presses the upper portion  2311  of the edge portion  231  to fix the edge portion  231 . In other words, even when the protective cover  280  and the upper portion  2311  of the edge portion  231  contact each other, each layer may slip at the edge portion  231 . In this case, the outermost layer (e.g., the encapsulation layer  613  of  FIG.  6 A ) of the layers of the flexible display  230  may be slipped, with a portion thereof in contact with the protective cover  280 . 
     According to an embodiment, a first space  710  may be formed between the protective cover  280  and the side portion  2312  of the edge portion  231 . The first space  710  may be formed in a size in which the extension  232  positioned at the side portion  2312  of the edge portion  231  may be spaced apart from the protective cover  280 . Here, the first space  710  may denote a space provided to prevent or reduce contact between the protective cover  280  and the extension  232  that is moved together as each layer of the flexible display  230  is slipped when the flexible display  230  is drawn in/out. Accordingly, while the flexible display  230  is drawn in and/or out, the extension  232  may be moved in the first space  710 . 
     According to an embodiment, as the first space  710  is provided in the electronic device  200 , the side portion  2312  of the edge portion  231  and/or the extension  232  may be protected from external impact. Specifically, as the first space  710  is provided, an external impact may not be directly transferred to the display driving chip provided on the side portion  2312  of the edge portion  231  and/or the extension  232 . Accordingly, as the first space  710  is provided, it is possible to prevent or reduce damage to the side portion  2312  of the edge portion  231  and/or the extension  232  which is vulnerable to external impact. 
     According to an embodiment, the second space  720  may be formed between the lower portion  2313  of the edge portion  231  and the first housing  210  (e.g., the bracket housing  215 ). The second space  720  may be provided so that the slip between the layers may smoothly occur when the flexible display  230  is drawn in and/or out. Or, the second space  720  may be provided so that the impact is not directly transferred to a portion of the extension  232  positioned under the edge portion  231  when there is external impact. 
     According to an embodiment, the protective cover  280  may be provided in a space between the side surface (e.g., the second side surface  2112  of  FIG.  2 A ) of the cover housing  214  and the bracket housing  215 . The curved portion  283  of the protective cover  280  may contact the inner side of the side surface (e.g., the second side surface  2112  of  FIG.  2 A ) of the cover housing  214 . The second portion  282  of the protective cover  280  may contact the bracket housing  215 . The protective cover  280  may be disposed along the length direction of the side surface (e.g., the second side surface  2112  of  FIG.  2 A ) of the cover housing  214 . 
     According to an embodiment, the bracket housing  215  may include a supporting member  2154  that contacts the protective cover  280  to support the protective cover  280 . The protective cover  280  may be seated on an inner surface of a side surface (e.g., the second side surface  2112  of  FIG.  2 A ) of the cover housing  214 . The curved portion  283  of the protective cover  280  may be formed to correspond to the shape of the inner side of the cover housing  214 . An additional component may be further included between the side surface (e.g., the second side surface  2112  of  FIG.  2 A ) of the cover housing  214  and the protective cover  280 . 
       FIG.  8    is a view illustrating a coupling relationship between a protective cover and a first housing (e.g., bracket housing) according to an embodiment. 
     Referring to  FIG.  8   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  and/or the protective cover  280  may be identical in whole or part to the corresponding configuration of the first housing  210 , the second housing  220 , the flexible display  230  and/or the protective cover  280  of  FIGS.  2  to  4    and/or  FIG.  7   . 
     According to an embodiment, the protective cover  280  may be fixedly coupled to a portion of the first housing  210  (e.g., the bracket housing  215 ). For example, a portion (e.g., the second portion  282  of  FIG.  7   ) of the protective cover  280  may be coupled to the supporting member  2154 . The supporting member  2154  may be formed to support the protective cover  280  on the bracket housing  215 . The coupling between the protective cover  280  and the first housing  210  (e.g., the bracket housing  215 ) may be made by one of schemes, such as screwing, welding, or bonding. As an example, the protective cover  280  may be coupled to the bracket housing  215  using a plurality of screws  810  from under the bracket housing  215  (e.g., the supporting member  2154 ). As another example, the protective cover  280  may be coupled to the bracket housing  215  by fastening a screw  810  from a side surface of the bracket housing  215  (e.g., the supporting member  2154 ). 
       FIGS.  9 A and  9 B  are views illustrating an area in which a fixed portion and a protective cover overlap according to the curvature of the fixed portion (e.g., edge portion) according to various embodiments. 
     Referring to  FIGS.  9 A and  9 B , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  and/or the protective cover  280  may be identical in whole or part to the configuration of the corresponding first housing  210 , the second housing  220 , the flexible display  230 , and/or the protective cover  280  of  FIGS.  2  to  4    and/or  FIG.  7   . 
     According to an embodiment, the length (e.g., the first length  910  or the second length  920 ) at which the protective cover  280  and the upper portion  2311  of the fixing portion (e.g., the edge portion  231 ) overlap may vary depending on the curvature R of the fixing portion (e.g., the edge portion  231 ) of the flexible display  230 . For example, as the curvature of the fixed portion (e.g., the edge portion  231 ) increases (or the radius of curvature decreases), that is, as the fixed portion (e.g., the edge portion  231 ) is more curved, the repulsive force of the fixed portion (e.g., the edge portion  231 ) may increase. To cover this repulsive force, the length (e.g., the first length  910  or the second length  920 ) at which the protective cover  280  and the upper portion  2311  of the fixed portion (e.g., the edge portion  231 ) overlap may increase. For example, as shown in  FIG.  9 A , when the radius of curvature of the fixed portion (e.g., the edge portion  231 ) is 10.35 R, the length (e.g., the first length  910 ) at which the first portion  281  of the protective cover  280  and the upper portion  2311  of the fixed portion (e.g., edge portion  231 ) overlap may be 1.1 mm As another example, as shown in  FIG.  9 B , when the radius of curvature of the fixed portion (e.g., the edge portion  231 ) is 7.0 R, the length (e.g., the second length  920 ) at which the first portion  281  of the protective cover  280  and the upper portion  2311  of the fixed portion (e.g., edge portion  231 ) overlap may be 1.5 mm which is larger than the first length  910 . 
     According to an embodiment, the length (e.g., the first length  910  or the second length  920 ) at which the protective cover  280  and the upper portion  2311  of the fixing portion (e.g., the edge portion  231 ) overlap may be determined depending on the number or type of the layers of the flexible display  230 . 
       FIG.  10    is a perspective view illustrating a placement relationship between a first housing and a protective cover according to an embodiment. 
     Referring to  FIG.  10   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  and/or the protective cover  280  may be identical in whole or part to the configuration of the corresponding first housing  210 , the second housing  220 , the flexible display  230  and/or the protective cover  280  of  FIGS.  2  to  4    and/or  FIG.  7   . 
     According to various embodiments, at least one antenna (e.g., second antenna A 2 ) may be provided on a side surface (e.g., second side surface  2112 ) of the first housing (e.g., the cover housing  214 ). According to an embodiment, a plurality of recesses (e.g., the recess  1010 ) and/or a plurality of protrusions may be formed inside the at least one antenna (e.g., the second antenna A 2 ), that is, on the surface contacting the protective cover  280 . According to an embodiment, the plurality of recesses (e.g., the recess  1010 ) and/or the plurality of protrusions of the antenna (e.g., the second antenna A 2 ) may be positioned in a conductive portion (e.g., the second conductive portion  321 ) of the antenna (e.g., the second antenna A 2 ). At least some of the plurality of protrusions of the antenna (e.g., the second antenna A 2 ) may be formed in the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ). According to an embodiment, the protective cover  280  may include a plurality of coupling portions  1020  corresponding to the plurality of protrusions and/or the plurality of recesses (e.g., the recesses  1010 ) formed in the antenna (e.g., the second antenna A 2 ). 
     For example, when a plurality of recesses (e.g., the recesses  1010 ) are formed in the inner surface of the antenna (e.g., the second antenna A 2 ), the protective cover  280  may form the coupling portions  1020  that protrude corresponding to the plurality of recesses (e.g., the recesses  1010 ) in the positions corresponding to the plurality of recesses (e.g., the recesses  1010 ). As another example, when the plurality of protrusions are formed on the inner surface of the antenna (e.g., the second antenna A 2 ), the protective cover  280  may form recessed coupling portions  1020  corresponding to the plurality of protrusions in the positions corresponding to the plurality of protrusions. 
     According to an embodiment, the plurality of recesses (e.g., the recesses  1010 ) and/or the plurality of protrusions of the antenna (e.g., the second antenna A 2 ) may be formed adjacent to the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) having a non-conductive material. The plurality of recesses (e.g., the recess  1010 ) and/or the plurality of protrusions may be formed on the two opposite sides of each segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) of the antenna (e.g., the second antenna A 2 ) and be configured in an even number. In this case, the plurality of coupling portions  1020  of the protective cover  280  may also be configured in an even number. 
     According to an embodiment, the plurality of coupling portions  1020  of the protective cover  280  may be coupled to the plurality of recesses (e.g., the recesses  1020 ) and/or the plurality of protrusions of the antenna (e.g., the second antenna A 2 ), fixing the conductive portion (e.g., the second conductive portion  321 ) adjacent to the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ). Accordingly, the coupling portion  1020  of the protective cover  280  may prevent or reduce the conductive portion (e.g., the second conductive portion  321 ) adjacent to the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) from being spaced apart from the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) and parting away from the segmenter (e.g., direction {circle around (5)}) when external impact is applied to the first housing  210  (e.g., the cover housing  214 ). If the conductive portion (e.g., the second conductive portion  321 ) adjacent to the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) is parted, the communication performance of the electronic device  200  may be deteriorated. The coupling portion  1020  of the protective cover  280  may fix two opposite sides of the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ), preventing or reducing deterioration of the communication performance due to external impact. 
       FIGS.  11 A,  11 B, and  11 C  are views illustrating a material of a portion of a protective cover corresponding to a segmenter according to various embodiments. 
     Referring to  FIGS.  11 A to  11 C , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  and/or the protective cover  280  may be identical in whole or part to the configuration of the corresponding first housing  210 , the second housing  220 , the flexible display  230 , and/or the protective cover  280  of  FIGS.  2  to  4    and/or  FIG.  7   . 
     According to an embodiment, a portion of the protective cover  280  may be formed of a conductive material (e.g., metal), and the rest may be formed of a non-conductive material (e.g., injection-molded one). For example, in the protective cover  280 , the conductive material (e.g., metal) and the non-conductive material (e.g., injection-molded one) may be integrally formed. 
     According to an embodiment, in the protective cover  280 , the section (e.g., the first section  280   a  or second section  280   b ) corresponding to the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) of the antenna (e.g., the second antenna A 2 ) provided on the side (e.g., the second side surface  2112 ) of the first housing  210  (e.g., the cover housing  214 ) may be formed of a non-conductive material (e.g., injection-molded one), and the rest (e.g., the third section  280   c ) may be formed of a conductive material (e.g., metal). The width (e.g., the first width  1120 ) of the portion (e.g., the first section  280   a ) formed of the non-conductive material (e.g., injection-molded one) in the protective cover  280  may be substantially equal to the width  1110  of, e.g., the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ). The portion contacting the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) in the first section  280   a  or the second section  280   b  of the protective cover  280  may be formed of, e.g., a non-conductive material (e.g., injection-molded one), and the rest adjacent to the flexible display  230  side may be formed of, e.g., a conductive material (e.g., metal). 
     According to an embodiment, the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) is a component for electrically insulating the conductive portions disposed on the two opposite sides. To prevent or reduce the conductive portion spaced apart by the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) from being electrically connected through the protective cover  280  contacting the antenna (e.g., the second antenna A 2 ), the section (e.g., the first section  280   a  or the second section  280   b ) corresponding to the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ) in the protective cover  280  may be formed of a non-conductive material (e.g., injection-molded one). 
     According to an embodiment, the width (e.g., the second width  1130 ) of the section (e.g., the second section  280   b ) formed of the non-conductive material (e.g., injection-molded one) in the protective cover  280  may be larger than the width  1110  of the segmenter (e.g., the third segmenter  3211  or the fourth segmenter  3212 ). According to some embodiments, the protective cover  280  may be overall formed of a non-conductive material (e.g., injection-molded one) or a conductive material (e.g., metal). 
       FIG.  12    is a cross-sectional view illustrating a ground structure of an antenna using a protective cover according to an embodiment. 
     Referring to  FIG.  12   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , second housing  220 , flexible display  230 , or protective cover  280  may be identical in whole or part to the configuration of the first housing  210 , the second housing  220 , the flexible display  230 , the flexible display  230 , or the protective cover  280  of  FIG.  2  to  4 ,  7   , or  10 . 
     According to an embodiment, the electronic device  200  may further include a conductive gasket (e.g., the first conductive gasket  1210  and the second conductive gasket  1220 ) disposed on the protective cover  280 . The first conductive gasket  1210  may be positioned at a portion in which the protective cover  280  contacts the antenna (e.g., the second antenna A 2 ) provided on the side surface (e.g., the second side surface  2112 ) of the cover housing  214 . Specifically, the first conductive gasket  1210  may be positioned between the protrusion  1230  of the second antenna A 2  and the recess-shaped coupling portion  1240  of the protective cover  280 . The second conductive gasket  1220  may be positioned at a portion where the protective cover  280  and the bracket housing  215  contact each other. The ground structure for allowing the current flowing through the antenna (e.g., the second antenna A 2 ) to flow to the bracket housing  215  through the protective cover  280  may be configured by providing, e.g., the first conductive gasket  1210  and the second conductive gasket  1220 . Accordingly, it is possible to omit a separate ground structure by replacing the ground structure for the antenna (e.g., the second antenna A 2 ) with the protective cover  280 . 
       FIG.  13    is a plan view illustrating a support sheet according to an embodiment. 
     The support sheet  270  of  FIG.  13    may be the same as or similar to the support sheet  270  illustrated in  FIG.  4   . 
     Referring to  FIG.  13   , the support sheet  270  may include a fixed portion (e.g., the fixed area  1310  corresponding to the first width W 1  of  FIG.  3 A ) of the flexible display  230  and a bending area  1320  corresponding to the rolling or bending portion (e.g., the second width W 2  of  FIG.  3 A ) of the flexible display  230 . The fixed area  1310  may be divided into a flat area  1311  corresponding to the flat portion of the flexible display  230  and an edge area  1312  corresponding to the fixed portion (e.g., the edge portion  231  of  FIG.  4   ). 
     According to an embodiment, the support sheet  270  may form a lattice structure  1312   a  in at least a portion of the bending area  1320  and the edge area  1312 , which are bends of the flexible display  230 . The lattice structure  1312   a  may include a plurality of openings  1312   b  and may contribute to the bendability of the flexible display  230 . The lattice structure  1312   a  may be referred to as an ‘opening pattern’. The plurality of openings  1312   b  may be formed, e.g., periodically and be arranged repeatedly with a predetermined interval in the same shape. In the support sheet  270 , the bending area  1320  and the edge area  1312  may have bendability by having the lattice structure  1312   a.    
     According to an embodiment, to implement an edge shape in the fixed portion (e.g., the edge portion  231 ), the degree of bending of the fixed portion (e.g., the edge portion  231 ) may be increased. In this case, the repulsive force of the fixed portion (e.g., the edge portion  231 ) is increased. According to an embodiment, the repulsive force of the fixed portion (e.g., the edge portion  231 ) may be reduced by increasing the width of the edge area  1312  of the support sheet  270  to broaden the area contributing to the bendability of the fixed portion (e.g., edge portion  231 ). For example, if the width of the edge area  1312  of the support sheet  270  is increased, the area of the lattice structure  1312   a  increases, thereby securing bendability of the fixed portion (e.g., the edge portion  231 ). If the bendability of the fixed portion (e.g., the edge portion  231 ) is secured, the support sheet  270  may be easily attached to the fixed portion (e.g., the edge portion  231 ). 
     According to an embodiment, the support sheet  270  may include a recess pattern (not shown) including a plurality of recesses, replacing the lattice structure  1312   a.  The recess pattern may contribute to bendability of the flexible display  230 . The support sheet  270  including a lattice structure and/or a recess pattern, and/or a conductive member corresponding thereto, may be formed of, e.g., a plurality of layers. 
       FIG.  14    is a cross-sectional view illustrating an electronic device including an anti-foreign body portion according to an embodiment. 
     Referring to  FIG.  14   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  280 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  or the protective cover  280  may be identical in whole or part to the configuration of the first housing  210 , the second housing  220 , the flexible display  230 , or the protective cover  280  of  FIGS.  2  to  4    or  FIG.  7   . 
     According to an embodiment, the electronic device  200  may further include anti-foreign body portion  1410  between the fixed portion (e.g., the edge portion  231 ) of the flexible display  230  and the protective cover  280 . The anti-foreign body portion  1410  may be positioned to contact an edge inner surface of the first portion  281  of the protective cover  280  and at least a portion of the fixed portion (e.g., the edge portion  231 ). In this case, the anti-foreign body portion  1410  may block the entrance of an external foreign body by sealing the gap between the protective cover  280  and the fixed portion (e.g., the edge portion  231 ). The anti-foreign body portion  1410  may be attached to, e.g., the protective cover  280  and/or the fixed portion (e.g., an edge portion  231 ). The anti-foreign body portion/material  1410  may be formed of a low-density elastic material, such as a sponge. 
       FIG.  15    is a view illustrating a protective cover and its surrounding configuration in an electronic device according to another embodiment. 
     Referring to  FIG.  15   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  1500 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  or the protective cover  280  may be identical in whole or part to the configuration of the first housing  210 , the second housing  220 , the flexible display  230 , or the protective cover  280  of  FIGS.  2  to  4    or  FIG.  7   . The electronic device  200  may have a display area of the first width W 1  in the closed state. 
     According to an embodiment, at least a portion of the area corresponding to the first width W 1  of the flexible display  230  (hereinafter, referred to as a “first width W 1  of the flexible display  230 ”) may be attached to the upper portion of the first housing  210  (e.g., the bracket housing  215  of  FIG.  4   ). The flexible printed circuit board (FPCB) may be provided to be electrically connected to an extension (e.g., the extension  232  of  FIG.  5 A ) of the rear surface of the first width W 1  of the flexible display  230 . Accordingly, when the first width W 1  of the flexible display  230  is attached to the first housing  210  (e.g., the bracket housing  215  of  FIG.  4   ), the fourth width W 4  which is the area provided with the flexible printed circuit board is not attached to the upper portion of the first housing  210  (e.g., the bracket housing  215  of  FIG.  4   ), but only the fifth width W 5 , which is the remaining area, may be attached to the upper portion of the first housing  210  (e.g., the bracket housing  215  of  FIG.  4   ) by an adhesive member, such as an adhesive tape. 
     According to an embodiment, the protective cover  280  may further include a fixing portion  1510  formed to extend in the direction parallel to the direction of the first width W 1  from two opposite ends in the length direction to press a portion of the flexible display  230 . Here, the length direction may be a direction substantially perpendicular to the direction of the first width W 1 . The fixing portion  1510  may be smaller than the length of the fourth width W 4 . The fixing portion  1510  may prevent or reduce a peel-off of the area corresponding to the fourth width W 4  of the flexible display  230 , preventing or reducing deterioration of the communication performance of the antennas (e.g., the first antenna A 1 , the second antenna A 2 , and the third antenna A 3  of  FIG.  2 A ) due to a movement of the flexible display  230 . 
       FIG.  16    is a cross-sectional view illustrating a protective cover for enhancing antenna communication performance according to another embodiment. 
     Referring to  FIG.  16   , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  1600 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  or the protective cover  280  may be identical in whole or part to the configuration of the first housing  210 , the second housing  220 , the flexible display  230 , or the protective cover  280  of  FIGS.  2  to  4    or  FIG.  7   . The portion of the protective cover  280 , overlapping the protective cover  280  of  FIG.  7   , is not further described. 
     According to an embodiment, the electronic device  200  further may include a protective cover  1600  disposed between at least the first housing  210  (e.g., the cover housing  214 ) and the flexible display  230  to protect the flexible display  230 . The protective cover  1600  may be disposed, e.g., between the second side surface (e.g., the second side surface  2112 ) of the cover housing  214  and the side surface (e.g., the side surface  2153  of  FIG.  4   ) of the bracket housing  215 . 
     According to an embodiment, the protective cover  1600  may include a third portion  1610 , a fourth portion  1620 , and/or a curved portion  1630 . A portion of the third portion  1610  of the protective cover  1600  may contact the flexible display  230 . A portion of the fourth portion  1620  of the protective cover  1600  may contact the first housing  210  (e.g., the bracket housing  215 ). A portion of the third portion  1610  and the outer surface of the curved portion  1630  of the protective cover  1600  may contact a side surface (e.g., the second side surface  2112 ) of the first housing  210  (e.g., the cover housing  214 ). 
     According to an embodiment, the third portion  1610  of the protective cover  1600  may protrude so that a portion thereof is visible from the outside. One side of the portion protruding from the third portion  1610  of the protective cover  1600  may be formed to cover the upper end of the side surface (e.g., the second side surface  2112 ) of the first housing  210  (e.g., the cover housing  214 ), and the other side may be formed to cover a portion of the fixed portion (e.g., the edge portion  231 ). The third portion  1610  of the protective cover  1600  may have a shape of approximately T-shaped. 
     The protective cover  280  may be formed so that the third portion  1610  protrudes upward, thus further increasing the distance D between the flexible display  230  and the antenna (e.g., the second antenna A 2 ). The protective cover  1600  may increase the distance between the flexible display  230  and the antenna (e.g., the second antenna A 2 ) as compared to the protective cover  280  of  FIG.  7   , enhancing the communication performance of the antenna (e.g., the second antenna A 2 ). 
       FIGS.  17 A and  17 B  are cross-sectional views illustrating a protective cover for reinforcing the performance of protecting an extension from external impact according to another embodiment. 
     Referring to  FIGS.  17 A and  17 B , an electronic device  200  may include a first housing  210 , a second housing  220 , a flexible display  230 , and/or a protective cover  1700 . The illustrated configuration of the first housing  210 , the second housing  220 , the flexible display  230  or the protective cover  280  may be identical in whole or part to the configuration of the first housing  210 , the second housing  220 , the flexible display  230 , or the protective cover  280  of  FIGS.  2  to  4    or  FIG.  7   . The portion of the protective cover  280 , overlapping the protective cover  1700  of  FIG.  7   , is not further described. 
     According to an embodiment, the electronic device  200  further may include a protective cover  1700  disposed between at least the first housing  210  (e.g., the cover housing  214 ) and the flexible display  230  to protect the flexible display  230 . The protective cover  1600  may be disposed, e.g., between the second side surface (e.g., the second side surface  2112 ) of the cover housing  214  and the side surface (e.g., the side surface  2153  of  FIG.  4   ) of the bracket housing  215 . 
     According to an embodiment, the protective cover  1700  may include a fifth portion  1710 , a sixth portion  1720 , and/or a curved portion  1730 . A portion of the fifth portion  1710  of the protective cover  1700  may contact the flexible display  230 . A portion of the sixth portion  1720  of the protective cover  1700  may contact the first housing  210  (e.g., the bracket housing  215 ). A portion of the fifth portion  1710  and the outer surface of the curved portion  1730  of the protective cover  1700  may contact a side surface (e.g., the second side surface  2112 ) of the first housing  210  (e.g., the cover housing  214 ). 
     According to an embodiment, the sixth portion  1720  of the protective cover  1700  may be disposed to extend in a substantially vertical direction. The vertical direction means a direction substantially perpendicular (e.g., perpendicular plus/minus 10 degrees or less) to the plane of the first area (e.g., the first area  230   a  of  FIG.  3 A ) of the flexible display  230 . Accordingly, the angle between the fifth portion  1710  and the sixth portion  1720  may be an obtuse angle. One surface of the sixth portion  1720  may face and contact the first housing  210  (e.g., the bracket housing  215 ). According to an embodiment, the protective cover  1700  may increase the area in contact with the first housing  210  (e.g., the bracket housing  215 ), more efficiently transferring external impact to the first housing  210  (e.g., the bracket housing  215 ). Accordingly, it is possible to more effectively protect the fixed portion (e.g., the edge portion  231 ) and/or the extension  232  from external impact. The sixth portion  1720  of the protective cover  1700  and the first housing  210  (e.g., the bracket housing  215 ) may be fastened to each other by, e.g., screwing. 
     According to an embodiment, the protective cover  1700  and the first housing  210  (e.g., the bracket housing  215 ) may be coupled by a connection member  1740 . When an impact is applied to the electronic device  200 , the impact applied to the first housing  210  (e.g., the cover housing  214 ) is transferred to the protective cover  1700 . The impact transferred to the protective cover  1700  is transferred to the inner first housing  210  (e.g., the bracket housing  215 ) through the connection member  1740 , so that the impact applied to the fixed portion (e.g., the edge portion  231 ) may be alleviated. 
     According to an embodiment, an electronic device (e.g., the electronic device  200  of  FIG.  2 A ) may comprise a first housing (e.g., the first housing  210  of  FIG.  4   ) including an antenna (e.g., the second antenna A 2  of  FIG.  2 A ) provided on a side surface thereof, a second housing (e.g., the second housing  220  of  FIG.  4   ) provided to slide in a first direction (e.g., direction {circle around (1)} of  FIG.  3 A ) to be at least partially drawn out of the first housing and to slide in a direction (e.g., direction {circle around (2)} of  FIG.  2 A ) opposite to the first direction to be drawn into the first housing, a flexible display (e.g., the flexible display  230  of  FIG.  4   ) including a first side having a fixed portion (e.g., the edge portion  231  of  FIG.  4   ) and a second side provided to be drawn out of an inside of the first housing and/or drawn into the inside of the first housing according to an operation of the second housing, and a protective cover (e.g., the protective cover  280  of  FIG.  4   ) provided between at least the fixed portion and the first housing to contact at least a portion of an upper portion (e.g., the upper portion  2311  of the edge portion of  FIG.  7   ) of the fixed portion. A first space (e.g., the first space  710  of  FIG.  7   ) may be provided between (directly or indirectly) the protective cover and a side portion (e.g., the side portion  2312  of  FIG.  7   ) of the fixed portion. 
     According to an embodiment, the first housing may include a supporting member (e.g., the supporting member  2154  of  FIG.  5 A ) fixing the protective cover. 
     According to an embodiment, an outer surface of the protective cover may be disposed to contact an inner surface of the antenna.
