For example, the inner glass layer (310) may include a sapphire glass material. For example, the inner glass layer (310) may include a high-hardness transparent material. The thickness of the inner glass layer (310) may be in the range of 10 μm to 50 μm.

Covers according to various embodiments of the present disclosure (e.g., covers (300, 400, 500, 600) of FIGS. 1 to 21c) can simultaneously improve deformation performance and rigidity of the cover (300) by arranging a filling layer (360) in a portion where deformation of the cover (300) occurs relatively large, and arranging a second glass layer (320) in a portion where deformation of the cover (300) occurs relatively small.

[0135] According to one embodiment, the cover (300) may include a first adhesive layer (331) and a second adhesive layer (332).

The adhesive layers (331, 332) may include a heat-reactive adhesive. The adhesive layers (331, 332) may include a general adhesive. The adhesive layers (331, 332) may include a double-sided tape. The thickness of the adhesive layers (331, 332) may be in the range of 0.05 um to 50 um.

[0136] According to one embodiment, the cover (300) may include an adhesive film layer (340). The adhesive film layer (340) may be connected to the first outer glass layer (321) and the second outer glass layer (322). The adhesive film layer (340) may be spaced apart from the inner glass layer (310). The adhesive film layer (340) may include a pressure sensitive adhesive (PSA) material. The adhesive film layer (340) may be referred to as a “buffer layer.” The adhesive film layer (340) may be referred to as a “third adhesive layer.” The adhesive film layer (340) may be referred to as a “pressure-sensitive adhesive film.” The adhesive film layer (340) may be referred to as a “film layer.” The adhesive film layer (340) may be referred to as a “bonding layer.” The adhesive film layer (340) may have a thickness in the range of 1 μm to 50 μm. The adhesive film layer (340) may be disposed between the second glass layer (320) and the protective layer (350), and may adhere the second glass layer (320) and the protective layer (350) to each other. The adhesive film layer (340) may be disposed between the filling layer (360) and the protective layer (350), and may adhere the filling layer (360) and the protective layer (350) to each other. The adhesive film layer (340) may have a higher hardness than the filling layer (360). The adhesive film layer (340) may have higher impact resistance than the filling layer (360).

[0137] According to one embodiment, the cover (300) may include a protective layer (350). The protective layer (350) may be connected to the adhesive film layer (340). The protective layer (350) may include a polymer material. The protective layer (350) may be referred to as a “polymer layer.” The protective layer (350) may form the outermost surface of the cover (300). The cover according to one embodiment of the present disclosure may include a second protective layer (not shown) disposed on one surface of the protective layer (350), and the second protective layer may form the outermost surface of the cover.

[0138] According to one embodiment, the cover (300) may include a filling layer (360). The filling layer (360) may be disposed within the cover folding area (303). The filling layer (360) may be disposed between the inner glass layer (310) and the adhesive film layer (340). The filling layer (360) may be disposed between the first outer glass layer (321) and the second outer glass layer (322). The filling layer (360) may be disposed between the first adhesive layer (331) and the second adhesive layer (332). The filling layer (360) may include a resin material. The filling layer (360) may include a viscous material. The filling layer (360) may be formed by hardening the viscous material.

[0139] According to one embodiment, the physical properties of the adhesive layer (330), the adhesive film layer (340), and the filling layer (360) may be different from each other. For example, the viscosity of the adhesive layer (330) and the viscosity of the filling layer (360) may be different from each other. The first viscosity of the adhesive layer (330) may be lower than the second viscosity of the filling layer (360). Since the first viscosity of the adhesive layer (330) is lower than the second viscosity of the filling layer (360), the thickness of the adhesive layer (330) may be formed lower than that of the filling layer (360).

[0140] According to one embodiment, the physical properties of the adhesive layer (330), the adhesive film layer (340), and the filling layer (360) may be substantially the same. For example, the refractive indices of the adhesive layer (330), the adhesive film layer (340), or the filling layer (360) may be substantially the same. The refractive indices of each of the adhesive layer (330), the adhesive film layer (340), and the filling layer (360) may be the same as the refractive index of the glass layers (310, 320).

[0141] According to one embodiment, the physical properties of the adhesive layer (330), the adhesive film layer (340), and the filling layer (360) may be different from each other. For example, the hardness of the adhesive layer (330) and the hardness of the adhesive film layer (340) may be different from each other. For example, the hardness of the adhesive layer (330) and the hardness of the filling layer (360) may be different from each other. For example, the hardness of the adhesive film layer (340) and the hardness of the filling layer (360) may be different from each other. The first hardness of the adhesive layer (330) may be greater than the second hardness of the adhesive film layer (340). The second hardness of the adhesive film layer (340) may be greater than the third hardness of the filling layer (360). Due to the hardness difference between the layers (330, 340, 360) described above, the strength of a part of the cover (300) with a relatively small degree of deformation can be improved, and the strain of another part of the cover (300) with a relatively large degree of deformation can be improved. The description of the hardness difference between the layers (330, 340, 360) described above can be equally applied to other physical properties (e.g., modulus, strength). For example, the first modulus of the adhesive layer (330) can be greater than the second modulus of the adhesive film layer (340), and the second modulus of the adhesive film layer (340) can be greater than the third modulus of the filling layer (360).

[0142] According to one embodiment, the electronic device (101) may include a housing (201) and a support member (205). A space may be formed inside the housing (201) and the support member (205), and the display (230) and the cover (300) may be placed inside the space.

[0143] In one embodiment, the housing (201) may include a base plate (2011). A support member (205) may be mounted on the base plate (2011). The housing (201) may include a first housing wall (2012) and a second housing wall (2013). The first and second housing walls (2012, 2013) may extend from the base plate (2011). The support member (205) may be disposed between the first housing wall (2012) and the second housing wall (2013).

[0144] In one embodiment, a support member (205) may be disposed within a housing (201). The support member (205) may be referred to as a “deco,” a “finishing member,” or a “display receiving member.” The support member (205) may include a support plate (2051). The support plate (2051) may be mounted on a base plate (2011). The support member (205) may include a first support wall (2052) and a second support wall (2053). The first support wall (2052) may face the first housing wall (2012). The second support wall (2053) may face the second housing wall (2013). The first and second support walls (2052, 2053) may extend from the support plate (2051). The display (230) may be placed between the first support wall (2052) and the second support wall (2053). The cover (300) may be placed between the first support wall (2052) and the second support wall (2053).

[0145] According to one embodiment, the inner glass layer (310) may include a first inner glass edge (312) and a second inner glass edge (313). The first inner glass edge (312) may be disposed within the first cover area (301). The second inner glass edge (313) may be disposed within the second cover area (302). The first inner glass edge (312) may be spaced apart from the first support wall (2052). The second inner glass edge (313) may be spaced apart from the second support wall (2053).

[0146] According to one embodiment, the first outer glass layer (321) may include a first side portion (3213). The first side portion (3213) may be disposed within the first cover area (301). The first side portion (3213) may be spaced apart from the first support wall (2052). The second outer glass layer (322) may include a second side portion (3223). The second side portion (3223) may be disposed within the second cover area (302). The second side portion (3223) may be spaced apart from the second support wall (2053).

[0147] According to one embodiment, a gap (D1) between the first inner glass edge (312) and the first support wall (2052) may be greater than a gap (D2) between the first side portion (3213) and the first support wall (2052). The first side portion (3213) may be positioned closer to the first support wall (2052) than the first inner glass edge (312). A gap (D3) between the first inner glass edge (312) and the first housing wall (2012) may be greater than a gap (D4) between the first side portion (3213) and the first housing wall (2012). The first side portion (3213) may be positioned closer to the first housing wall (2012) than the first inner glass edge (312).

[0148] According to one embodiment, the side portions (3213, 3223) of the second glass layer (320) may be positioned closer to the display side surface (2308) than the edges (312, 313) of the first glass layer (310). For example, the first gap between the second side portion (3223) of the second glass layer (320) and the display side surface (2308) may be smaller than the second gap between the second inner glass edge (313) of the first glass layer (310) and the display side surface (2308). Due to the above-described structure, when a predetermined operation (e.g., pressing or impact) is applied to the cover (300) and the display (230), the risk of damage to the first glass layer (310) may be reduced. For example, when a predetermined action (e.g., pressing or impact) is applied to the cover (300) and the display (230), the second glass layer (320) covers the first glass layer (310) at the end portion of the cover (300), thereby reducing the risk of damage to the first glass layer (310).

[0149] According to one embodiment, the side portions (3213, 3223) of the second glass layer (320) may be positioned closer to the side surfaces (e.g., the side surfaces (300a, 300b) of FIG. 7) of the cover (300) than the edges (312, 313) of the first glass layer (310). For example, the first gap between the first side portion (3213) of the second glass layer (320) and the first surface (300a) may be smaller than the second gap between the first inner glass edge (312) of the first glass layer (310) and the first surface (300a). For example, the first gap between the second side portion (3223) of the second glass layer (320) and the second surface (300b) may be smaller than the second gap between the second inner glass edge (313) of the first glass layer (310) and the second surface (300b). Due to the above-described structure, when a predetermined operation (e.g., pressing or impact) is applied to the cover (300) and the display (230), the risk of damage to the first glass layer (310) may be reduced. For example, when a predetermined operation (e.g., pressing or impact) is applied to the cover (300) and the display (230), the second glass layer (320) covers the first glass layer (310) at the end portion of the cover (300), thereby reducing the risk of damage to the first glass layer (310).

[0150] According to one embodiment, a gap (D5) between the second inner glass edge (313) and the second support wall (2053) may be greater than a gap (D6) between the second side portion (3223) and the second support wall (2053). The second side portion (3223) may be positioned closer to the second support wall (2053) than the second inner glass edge (313). A gap (D7) between the second inner glass edge (313) and the second housing wall (2013) may be greater than a gap (D8) between the second side portion (3223) and the second housing wall (2013). The second side portion (3223) may be positioned closer to the second housing wall (2013) than the second inner glass edge (313).

The second glass layers (321, 322) may be positioned at a position that does not overlap with the third reinforcing region (2353). The second glass layers (321, 322) may be misaligned with the third reinforcing region (2353) in the thickness direction of the display (230). For example, the first reinforcing boundary portion (2353a) and the second reinforcing boundary portion (2353b) may be positioned within the folding area (233) of the display (230), and the first outer glass layer (321) and the second outer glass layer (322) may be positioned at positions that do not correspond to the folding area (233) of the display (230). The first outer glass layer (321) may be positioned at a position corresponding to the first display area (231) of the display (230). The second outer glass layer (322) may be positioned at a position corresponding to the second display area (232). Due to the position of the second glass layer (320) described above, the deformation ability in the folding area (233) may be improved.
