[0030] The invention will now be described more fully below with reference to the accompanying drawings, in which various embodiments are shown. However, the invention may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Throughout the text, the same reference numerals or symbols refer to the same elements.

[0031] It will be understood that when an element or layer is referred to as being "on" another element or layer "on top" or "on" another element or layer, it includes not only the case where it is directly disposed on the other element or layer, but also the case where an intermediate element is disposed between the element or layer and the other element or layer. Conversely, when an element is referred to as being "directly disposed on" or "disposed on top of," it means that there are no intermediate layers or elements therebetween.

[0032] The terms used herein are only used to describe the purpose of a particular embodiment and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, "one", "one (kind / person)", "the (said)" and "at least one (kind / person)" do not represent the limitation of quantity, and are intended to include both the singular and the plural. For example, unless the context clearly indicates otherwise, "element" has the same meaning as "at least one element". "At least one (kind / person)" should not be interpreted as being limited to "one" or "one (kind / person)". "Or" means "and / or". As used herein, the term "and / or" includes any combination and all combinations of one or more of the related listed items. It will also be understood that the term "include" or "comprising" and / or its variations when used in this specification, illustrate the existence of stated features, regions, wholes, steps, operations, elements and / or components, but do not exclude the existence or addition of one or more other features, regions, wholes, steps, operations, elements, components and / or their groups.

[0033] For ease of description, spatially relative terms such as "below", "under", "lower", "above", "upper", etc. may be used herein to describe the relationship of one element or feature to another element or feature as shown in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings.

[0034] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components and / or parts, these elements, components and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component or part from another element, component or part. Therefore, without departing from the teaching of the invention, the first element, component or part discussed below may be referred to as the second element, component or part.

[0035] As used herein, "about" or "approximately" is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0036] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. It will also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

[0037] Embodiments are described herein with reference to cross-sectional views which are schematic diagrams of idealized embodiments. As such, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are to be expected. Therefore, the embodiments described herein should not be construed as being limited to the specific shapes of the regions as shown herein, but rather will include deviations in shape due to, for example, manufacturing. For example, a region shown or described as flat may typically have rough and / or nonlinear features. In addition, the acute angles shown may be rounded. Therefore, the regions shown in the accompanying drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

[0038] Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 is a perspective view of a display device according to an embodiment of the invention. Figure 2 It is shown from Figure 1 A view of the display module with the housing pulled out is shown in FIG.

[0041] In the embodiment, the housing HS may have a hexahedral shape, but the shape of the housing HS is not limited thereto. The housing HS may extend more (or longer) in a second direction DR2 crossing the first direction DR1 than in the first direction DR1.

[0042] Hereinafter, a direction substantially perpendicular to a plane defined by the first direction DR1 and the second direction DR2 is defined as a third direction DR3. In this specification, the wording "when viewed on a plane" may refer to a state viewed in the third direction DR3.

[0043] The housing opening HOP may be defined in one side of opposite sides of the housing HS that are opposite to each other in the first direction DR1. The housing opening HOP may be closer to the upper portion of the housing HS than to the lower portion of the housing HS.

[0044] The display module DM can be pulled in and out through the housing opening HOP by being wound around a roller provided in the housing HS. However, the embodiments of the invention are not limited thereto, and the display module DM can be pulled out to the outside by sliding from the inside to the outside of the housing HS without using a roller. Hereinafter, for the convenience of description, an embodiment having a configuration in which the display module DM is wound around a roller will be described in detail below.

[0045] The handle HND may be disposed outside the housing HS and adjacent to the housing opening HOP. The handle HND may be adjacent to the upper portion of the housing HS. The handle HND may be movable in a first direction DR1. When the handle HND moves in the first direction DR1 to move away from the housing HS, the display module DM may be pulled out to the outside of the housing HS through the housing opening HOP. The handle HND may be manipulated by a user.

[0046] In an embodiment, Figure 1 The state in which the display module DM shown in FIG. 1 is disposed inside the housing HS and is not exposed to the outside can be defined as a closed mode. Figure 2 An operation in which the display module DM is exposed to the outside of the housing HS as shown in FIG. 1 may be defined as an open mode. In the open mode, the exposed portion of the display module DM may be expanded.

[0047] The support portion SUP may be disposed on opposite sides of the display module DM that are opposite to each other in the second direction DR2 to support the display module DM. The support portion SUP may include a first support portion SUP1 adjacent to one side of the display module DM and a second support portion SUP2 adjacent to the other side of the display module DM. The one side of the display module DM and the other side of the display module DM may be opposite sides of the display module DM that are opposite to each other in the second direction DR2.

[0049] Reference Figure 3 , an embodiment of the display device DD may include a housing HS, a display module DM, a roll ROL, a module support MSP, a support SUP, and a handle HND. The display module DM, the roll ROL, the module support MSP, and the support SUP may be accommodated in the housing HS.

[0050] In the housing HS, the roller ROL may be adjacent to the other side of the housing HS, which is the opposite side of the housing HS to the side of the housing opening HOP. When viewed in the second direction DR2, the roller ROL may have a circular shape. In an embodiment, for example, the roller ROL may have a cylindrical shape extending in the second direction DR2. The roller ROL may rotate clockwise or counterclockwise. Although not shown, the display device DD may further include a driving portion for rotating the roller ROL.

[0051] The display module DM may extend in the first direction DR1 and be wound around the roller ROL. One end of the display module DM may be connected to the roller ROL. The display module DM may be arranged in such a manner that a portion of the display module DM is wound around the roller ROL, and another portion of the display module DM is not wound around the roller ROL and overlaps the support portion SUP. The other end of the display module DM, opposite to the one end of the display module DM connected to the roller ROL, may be connected to the handle HND. The other end of the display module DM may be adjacent to the housing opening HOP.

[0052] The front surface of the display module DM may be defined as a surface on which an image is displayed. The module support part MSP may be disposed on one surface of the display module DM. The module support part MSP may be disposed on an opposite surface of the front surface of the display module DM. In an embodiment, for example, the module support part MSP may be disposed below the lower surface of the display module DM. Hereinafter, one surface of the display module DM may be defined as the lower surface of the display module.

[0053] The module support part MSP may be attached to one surface of the display module DM. In an embodiment, for example, the module support part MSP may be attached to the rear surface (or lower surface) of the display module DM by a pressure-sensitive adhesive.

[0054] The module support part MSP may extend in the first direction DR1 and be wound around the roller ROL. One end of the module support part MSP may be connected to the roller ROL, and the other end of the module support part MSP may be connected to the handle HND. The other end of the module support part MSP may be adjacent to the housing opening HOP. The module support part MSP may be arranged in such a manner that a portion of the module support part MSP is wound around the roller ROL, and another portion of the module support part MSP is not wound around the roller ROL and overlaps with the support part SUP.

[0055] The module support part MSP may include a support layer SPL disposed under the display module DM and extending in the first direction DR1, a support member SPP disposed in the support layer SPL, and a magnetic particle layer SMP disposed adjacent to the support member SPP in the support layer SPL. The support member SPP may have a greater rigidity than the support layer SPL. In an embodiment, for example, Figure 3 As shown in FIG. 1 , the support member SPP may include a plurality of support bars SB arranged in a first direction DR1, and the support member SPP may include a plate having an opening OP defined therein. Fig.13 The shape of the support member SPP is described in more detail.

[0056] One end of the supporting layer SPL may be connected to the roller ROL, and the other end of the supporting layer SPL may be connected to the handle HND. The other end of the supporting layer SPL may be adjacent to the housing opening HOP. The supporting layer SPL may be arranged in such a manner that a portion of the supporting layer SPL is wound around the roller ROL, and another portion of the supporting layer SPL is not wound around the roller ROL and overlaps the supporting portion SUP.

[0057] When viewed in the second direction DR2, the support bar SB may have a quadrilateral shape. However, the shape of the side surface of the support bar SB is not limited thereto, and the support bar SB may have various shapes. Figures 17a to 17d The shape of the support bar SB is described in more detail.

[0058] The magnetic particle layer SMP may be disposed in the support layer SPL. The magnetic particle layer SMP may be disposed on top and / or below (above and / or below, or on the upper surface and / or lower surface) of the support member SPP. In an embodiment, for example, the magnetic particle layer SMP may be disposed on one surface of the support bar SB. The magnetic particle layer SMP may overlap the support member SPP in the thickness direction of the support layer SPL in which the magnetic particle layer SMP and the support member SPP are disposed. This will be referred to later. Figure 10a to Figure 10b The construction of the supporting strips SB and the magnetic particle layer SMP is described in more detail.

[0059] The display module DM and the module support part MSP can be pulled in and out through the housing opening HOP. One end of the support part SUP can be connected to the handle HND. The support part SUP can extend in the first direction DR1 like an antenna. The construction of the support part SUP will be described in more detail later.

[0060] The support portion SUP may include a guide groove GG defined therein. The module support portion MSP may be disposed in the guide groove GG and move along the guide groove GG in the first direction DR1. The module support portion MSP may be disposed in the guide groove GG to be supported by the support portion SUP, and the module support portion MSP may support the display module DM. That is, the support portion SUP may basically play a role in supporting the display module DM.

[0061] Figure 4 It is along Figure 2 A cross-sectional view taken along line II-II' shown in FIG.

[0062] Reference Figure 4 , the handle HND can be moved away from the housing HS in the first direction DR1. When the handle HND moves, the display module DM and the module support part MSP connected to the handle HND can move in the first direction DR1. The display module DM and the module support part MSP can be unfolded from the roller ROL, and the unfolded display module DM and the module support part MSP can be pulled out to the outside of the housing HS through the housing opening HOP. Therefore, the exposed part of the display module DM can be expanded.

[0063] As the handle HND moves, when the display module DM and the module support MSP are pulled out of the housing HS, the support SUP connected to the handle HND can be extended to the outside of the housing HS through the housing opening HOP. The support SUP can be extended to the outside of the housing HS and support the display module DM outside the housing HS.

[0064] The module supporting part MSP having moved to the outside of the housing HS may be supported by the supporting part SUP, and the module supporting part MSP supported by the supporting part SUP may support the display module DM.

[0065] The support portion SUP may include a first extension portion EX1, a second extension portion EX2, and a third extension portion EX3 to extend to the outside of the housing HS. The second extension portion EX2 may be disposed between the first extension portion EX1 and the third extension portion EX3.

[0066] In an embodiment, the second extension EX2 can be pulled in and out from the first extension EX1, and the third extension EX3 can be pulled in and out from the second extension EX2, so that an expandable structure similar to an antenna can be realized. The first extension EX1 can be arranged inside the housing HS, and the second extension EX2 and the third extension EX3 can be moved to the outside of the housing HS. The third extension EX3 can be connected to the handle HND.

[0067] The first extension part EX1, the second extension part EX2, and the third extension part EX3 may include guide grooves GG defined therein, respectively. The guide grooves GG defined in the first extension part EX1, the second extension part EX2, and the third extension part EX3 may be defined as continuous spaces overlapping each other in the first direction DR1. The module support part MSP may be disposed in the guide grooves GG.

[0068] When the handle HND moves in the first direction DR1 to approach the housing HS, the handle HND may be disposed adjacent to the housing opening HOP outside the housing HS, such as Figure 3 As the handle HND moves, the support portion SUP may be retracted in the first direction DR1 to be disposed inside the housing HS, and the display module DM and the module support portion MSP may be pulled into the housing HS.

[0069] Figure 5 is shown to be accommodated in Figure 1 0026] A view of a display module in a housing is shown in FIG.

[0070] Reference Figure 5 , an embodiment of the display module DM may have a rectangular shape having long sides extending in the first direction DR1 and short sides extending in the second direction DR2. However, embodiments of the invention are not limited thereto, and the display module DM may have various shapes such as a circular shape or a polygonal shape.

[0071] An upper surface of the display module DM may be defined as a display surface DS and have a plane defined by a first direction DR1 and a second direction DR2. An image IM generated by the display module DM through the display surface DS may be provided to a user.

[0074] Reference Figure 6 , the display module DM may be a flexible or rollable display module. The display module DM may be rolled like a scroll. The display module DM may be rolled in a first direction DR1. The display module DM may be rolled from one side of the display module DM. The display module DM may be rolled toward the outside of the display surface DS. However, embodiments of the invention are not limited thereto, and the display module DM may be rolled toward the inside of the display surface DS.

[0080] The anti-reflection layer RPL may be provided on the input detection part ISP. The anti-reflection layer RPL may be directly formed on the input detection part ISP or bonded to the input detection part ISP through an adhesive layer. The anti-reflection layer RPL may be defined as an anti-external light reflection film. The anti-reflection layer RPL may reduce the reflectivity of external light incident from above the display device DD toward the display panel DP.

[0081] When external light emitted toward the display panel DP is reflected from the display panel DP and provided to an external user again, the external light may be seen by the user as if reflected from a mirror. In an embodiment, for example, the anti-reflection layer RPL may include a plurality of color filters that display the same color as the pixels of the display panel DP to reduce such reflection of external light.

[0082] The color filter may filter external light of the same color as the pixel. In this case, the external light may not be seen by the user. However, the embodiments of the invention are not limited thereto, and the anti-reflection layer RPL may include a polarizing film for reducing the reflectivity of the external light. The polarizing film may include a retarder and / or a polarizer.

[0083] The window WIN may be disposed on the anti-reflection layer RPL. In an embodiment, the window WIN may be directly formed on the anti-reflection layer RPL or bonded to the anti-reflection layer RPL through an adhesive layer. The window WIN may protect the display panel DP, the input detection part ISP, and the anti-reflection layer RPL from external scratches and impacts.

[0106] Fig.10a and Fig.10b It is shown Figure 3 and Figure 4 A view of a module support and a portion of a display module shown in FIG.

[0107] In particular, Fig.10a is a perspective view showing the module support part MSP in a flat state, Fig.10b is a view showing the module supporting part MSP when viewed in the second direction DR2.

[0108] Fig.10a and Fig.10b An embodiment is shown in which the support member SPP includes or is defined by a plurality of support bars SB.

[0109] Reference Fig.10a and Fig.10b , the module support part MSP may be disposed on one surface of the display module DM. In an embodiment, for example, the module support part MSP may be disposed below or on the lower surface of the display module DM. The module support part MSP may include a support member SPP, a support layer SPL, and a magnetic particle layer SMP.

[0110] In an embodiment, for example, the support member SPP may include a support bar SB. The support bar SB may be arranged in the first direction DR1 and extend in the second direction DR2. Fig.10a, the support bars SB arranged in the support layer SPL are shown as dotted lines. The support bars SB may be spaced apart from each other in the first direction DR1. The interval between two support bars SB adjacent to each other may be in the range of about 100 micrometers to about 200 micrometers. The support bars SB may be spaced apart from each other at regular intervals in the first direction DR1, but the interval between the support bars SB is not limited thereto.

[0111] The support bar SB may be of a rigid type. In an embodiment, for example, the support bar SB may include a metal. The support bar SB may include aluminum, stainless steel, or Invar. In such an embodiment, the support bar SB may include a metal attracted by a magnet. However, the support bar SB is not limited thereto and may include a carbon fiber reinforced plastic (CFRP).

[0112] One surface BUS of the surfaces of each of the support bars SB that are opposite to each other in the third direction DR3 may face the display module DM. The opposite ends of each of the support bars SB that are opposite to each other in the second direction DR2 may not be disposed in the support layer SPL and may be exposed to the outside. The opposite ends of each of the support bars SB may be exposed to the outside according to the method of manufacturing the module support part MSP, and will be referred to later. Figures 16a to 16g The manufacturing method is described in detail.

[0113] In an embodiment, Fig.10a As shown in FIG. 1 , when the module support part MSP is viewed in the second direction DR2, the support bar SB may have a quadrilateral shape. However, the shape of the side surface of the support bar SB is not limited thereto, and the support bar SB may have various shapes. Figures 18a to 18d The shapes of various embodiments of the support bar SB are described.

[0114] The support layer SPL may include an elastic polymer having a predetermined elastic force. In an embodiment, for example, the support layer SPL may include an elastic polymer such as polyurethane or silicone.

[0115] The rigidity of the support bar SB may be greater than the rigidity of the support layer SPL. The elastic modulus of the support bar SB may be greater than the elastic modulus of the support layer SPL. In an embodiment, the support layer SPL may have an elastic modulus in the range of about 20 kilopascals (KPa) to about 20 megapascals (MPa). In such an embodiment, the support bar SB may have an elastic modulus in the range of about 1 gigapascals (GPa) to about 200 gigapascals (GPa).

[0116] The magnetic particle layer SMP may be disposed in the supporting layer SPL. The magnetic particle layer SMP may be disposed in the supporting layer SPL adjacent to one surface SUS of the supporting layer SPL. The magnetic particle layer SMP may be disposed on one surface BUS of each of the supporting bars SB facing the display module DM. The magnetic particle layer SMP may be disposed adjacent to the supporting bars SB. In an embodiment, for example, the magnetic particle layer may be disposed on top of the supporting bars SB.

[0117] The magnetic particle layer SMP may be disposed adjacent to one surface of the support layer SPL facing the display module DM. The magnetic particle layer SMP may be adjacent to one surface of the support layer SPL and include a plurality of magnetic particle patterns. The magnetic particle patterns of the magnetic particle layer SMP may be arranged along the support bars SB in the first direction DR1 and extend in the second direction DR2.

[0118] The magnetic particle layer SMP may include a plurality of particles MP each having magnetic properties. In an embodiment, for example, the particles MP of the magnetic particle layer SMP may include iron, cobalt, nickel, iron oxide, chromium oxide, or ferrite. The particles MP of the magnetic particle layer SMP may each have a size in the range of about 500 nanometers to about 10 micrometers. The size of each particle MP may be defined as the diameter (or maximum width) of each particle MP.

[0119] The elastic modulus of the particles MP of the magnetic particle layer SMP may be greater than the elastic modulus of the support layer SPL. In an embodiment, for example, the particles MP may have an elastic modulus of about 60 megapascals (MPa).

[0120] The magnetic particle layer SMP may be disposed on one surface of each of the support bars SB facing the display module DM. In an embodiment, for example, when viewed on a plane, the density of the particles MP disposed in a portion of the magnetic particle layer SMP located between two support bars SB adjacent to each other may be smaller than the density of the particles MP disposed in a portion of the magnetic particle layer SMP located on one surface of each of the support bars SB. However, the density of the particles MP may not be limited thereto. This will be described later with reference to Figures 11a to 11c The density of the particles MP is described in more detail.

[0121] In an embodiment, the support layer SPL may be formed by curing resin. The module support part MSP may have a structure in which a rigid support bar SB is immersed in the support layer SPL. When an impact is applied to the display module DM, the impact may be transmitted to the module support part MSP, which causes deformation of the support layer SPL. When the support layer SPL is deformed, a deflection is formed in the support layer SPL, and the display module DM disposed on the support layer SPL on which the deflection is formed also has the deflection thereon. This may cause defects such as deterioration of the surface quality of the display module DM.

[0122] In addition, when the display module DM is rolled around and unrolled from the roll ROL, static electricity may be generated on the surface of the display module DM due to friction, etc. The static electricity may cause damage to the display module DM.

[0123] In an embodiment, Fig.10a and Fig.10b As shown in the figure, a magnetic particle layer SMP having an elastic modulus larger than that of the supporting layer SPL is arranged in a region adjacent to a surface SUS of the supporting layer SPL facing the display module DM (or a region in the supporting layer SPL located between the supporting bar SB and the display module DM), thereby enhancing the impact resistance of the module supporting part MSP.

[0124] Table 1

[0125]

[0126] Table 1 shows an experimental example for confirming impact resistance. A test for confirming impact resistance can be performed by a pen drop test. Figure 7 The pen drop experiment was performed on the display module DM and the module support part MSP in Table 1. The height shown in Table 1 may be a height that may cause damage to the display module DM and the module support part MSP when the pen falls from this height. Referring to Table 1, it can be seen that when the magnetic particle layer SMP including particles MP is provided on one surface BUS of each of the support bars SB, the drop height of the pen increases. It can be seen that when the magnetic particle layer SMP is provided on one surface BUS of each of the support bars SB and between the support bars adjacent to each other, the drop height of the pen increases.

[0127] Therefore, in the embodiment, even when an impact is applied to the display module DM, the magnetic particle layer SMP can enhance the impact resistance of the module support part MSP, thereby effectively preventing deformation of the support layer SPL. Therefore, the surface quality of the display module DM can be improved.

[0128] In such an embodiment, since the magnetic particle layer SMP includes particles MP having magnetic properties, static electricity generated on the surface of the display module DM during the winding and unwinding of the display module DM can be discharged due to the particles MP. In such an embodiment, the particles MP can be used as a ground, so that the display module DM can be effectively prevented from being damaged due to static electricity.

[0132] Reference Fig.11a In an embodiment, the density of the particles MP disposed in a portion of the magnetic particle layer SMP located between mutually adjacent support strips SB may be the same as the density of the particles MP disposed in a portion of the magnetic particle layer SMP located on a surface BUS of each of the support strips SB.

[0133] Reference Fig.11b In an optional embodiment, the density of the particles MP disposed in the portion of the magnetic particle layer SMP located between the support bars SB adjacent to each other may be greater than the density of the particles MP disposed in the portion of the magnetic particle layer SMP located on one surface BUS of each of the support bars SB. In an embodiment, for example, the interval between two support bars adjacent to each other among the support bars may be in the range of about 500 μm to about 1 mm.

[0134] Reference Fig.11c In another optional embodiment, the magnetic particle layer SMP may be further disposed under the support bars SB. The module support portion MSP may further include a magnetic particle layer SMP on a surface of each of the support bars SB that is opposite to the one surface BUS in the third direction DR3. The support bars SB may be arranged between the magnetic particle layers SMP.

[0135] Figures 12a to 12d An image of a module support is shown.

[0136] Specifically, Figures 12a to 12d 2 is an image showing the module supporting parts MSP and MSP' after an impact is applied thereto.

[0137] Specifically, Figures 12a to 12c is an image of a module support MSP including a magnetic particle layer SMP, Fig.12d is an image of a module support portion MSP' that does not include a magnetic granular layer SMP.

[0138] Reference Fig.12a , Figure 12b and Fig.12dIt can be confirmed that when the density of the particles MP disposed in the portion of the magnetic particle layer SMP located on one surface BUS of each of the support bars SB is greater than the density of the particles MP in the portion of the magnetic particle layer SMP located between the support bars SB adjacent to each other, the surface quality is improved even when an external impact is applied. Specifically, Fig.12a and Figure 12b The upper surface of the module support part MSP to which the external impact is applied may be flat, but Fig.12d The upper surface of the module support part MSP' shown in FIG. 1 may not be flat when an external impact is applied.

[0139] Reference Fig.12c and Fig.12d It can be confirmed that when the density of the particles MP in the portion of the magnetic particle layer SMP disposed on one surface BUS of each of the support bars SB is the same as the density of the particles MP in the portion of the magnetic particle layer SMP disposed between the support bars SB adjacent to each other, the surface quality is improved even if an external impact is applied. Specifically, Fig.12c The upper surface of the module support part MSP shown in FIG. 1 may be flat even when an external impact is applied thereto, but Fig.12d The upper surface of the module support part MSP' shown in FIG. 1 may not be flat when an external impact is applied thereto.

In an embodiment, for example, the support plate PLT may be provided with a plurality of openings OP defined therein. The openings OP may be arranged according to a predetermined rule. The openings OP may have a grid-like arrangement, and the grid pattern may be formed in the entire area of ​​the support plate PLT.

[0142] Since the opening OP is defined in the entire area of ​​the support plate PLT, the area of ​​the support plate PLT can be reduced, and thus the rigidity of the support plate PLT can be reduced. Therefore, the support plate PLT can be more flexible in such an embodiment in which the opening OP is defined in the support plate PLT than in an embodiment in which the opening OP is not defined in the support plate PLT. Therefore, in such an embodiment, the support plate PLT can be more easily curled.

[0143] Reference Fig.13 and Fig.14, the openings OP may be arranged in the first direction DR1 and the second direction DR2. The openings OP may extend further in the second direction DR2 than in the first direction DR1.

[0144] The openings OP may include a plurality of first openings OP1 arranged in the second direction DR2 and a plurality of second openings OP2 adjacent to the first openings OP1 in the first direction DR1 and arranged in the second direction DR2.

The magnetic particle layer SMP may be disposed on the top (or upper surface) of the support plate PLT. The density of particles MP disposed in the portion of the magnetic particle layer SMP located on the first branch portion BR1 and the second branch portion BR2 may be greater than the density of particles MP disposed in the portion of the magnetic particle layer SMP located on the opening OP.

[0150] Reference Fig.15bIn an optional embodiment, the magnetic particle layer SMP may be disposed on a surface BUS of the support plate PLT facing the display module DM. The magnetic particle layer SMP may be disposed on the top of the support plate PLT. The density of the particles MP disposed in the portion of the magnetic particle layer SMP located on the first branch portion BR1 and the second branch portion BR2 may be the same as the density of the particles MP disposed in the portion of the magnetic particle layer SMP located on the opening OP.

[0151] Reference Fig.15c In another optional embodiment, the magnetic particle layer SMP may be disposed on a surface BUS of the support plate PLT facing the display module DM. The magnetic particle layer SMP may be disposed on the top of the support plate PLT. The density of the particles MP disposed in the portion of the magnetic particle layer SMP located on the first branch portion BR1 and the second branch portion BR2 may be less than the density of the particles MP disposed in the portion of the magnetic particle layer SMP located on the opening OP.

[0152] Although not shown, the magnetic particle layer SMP may also be provided on the support plate PLT in the third direction DR3. Figures 15a to 15c The one surface BUS shown in FIG.

[0153] The magnetic particle layer SMP having an elastic modulus greater than that of the support layer SPL is disposed on one surface BUS of the support plate PLT facing the display module DM, so that the impact resistance of the module support part MSP can be enhanced.

[0154] In such an embodiment, even when an impact is applied to the display module DM, the impact resistance of the module support part MSP can be enhanced due to the magnetic particle layer SMP, thereby effectively preventing the support layer SPL from being deformed. Therefore, the surface quality of the display module DM can be improved.

[0155] In such an embodiment, since the magnetic particle layer SMP includes particles MP having magnetic properties, when the display module DM is rolled and unrolled, static electricity generated on the surface of the display module DM can be discharged due to the particles MP. The particles MP can be used as a ground. Therefore, the display module DM can be effectively prevented from being damaged due to static electricity.
