[0059] refer to Figure 1, the display device 10 according to the present embodiment may be a foldable display device. The case where the display device 10 is applied to a smart phone will be described herein, but the present disclosure is not limited to this case. For example, the display device 10 according to one or more embodiments of the present specification can be applied not only to a smart phone, but also to a mobile phone, a tablet PC, a personal digital assistant (PDA), a portable multimedia player (PMP), a television, a game console, a watch-type or watch-type electronic device, a head-mounted display, a PC monitor, a notebook computer, a car navigation system, a car dashboard, a digital camera, a video camera, an outdoor billboard, an electronic display board, a medical device, an inspection device, one or more suitable household appliances (such as refrigerators and washing machines) or an Internet of Things (IoT) device. Specific embodiments will be described with reference to the accompanying drawings.

[0060] exist Figure 1 and Figure 2 In the embodiment, when viewed in a plan view, the first direction DR1 may be a direction parallel to one side of the display device 10 (for example, may be a horizontal direction (for example, an X-axis direction) of the display device 10). When viewed in a plan view, the second direction DR2 may be a direction parallel to the other side in contact with the above-mentioned side of the display device 10 (for example, may be a vertical direction (for example, a Y-axis direction) of the display device 10). The third direction DR3 may be a thickness direction of the display device 10.

[0061] In one or more embodiments, the display device 10 may be rectangular in plan view. In plan view, the display device 10 may be shaped as a rectangle having right-angled corners or a rectangle having rounded corners. In plan view, the display device 10 may include two short sides extending in the first direction DR1 and two long sides extending in the second direction DR2.

[0062] The display device 10 includes a display area DA and a non-display area NDA. In a plan view, the shape of the display area DA may correspond to the shape of the display device 10. For example, in a plan view, when the display device 10 is rectangular, the display area DA may also be rectangular.

[0063] The display area DA may include a plurality of pixels for displaying an image. The pixels may be arranged in a matrix direction. In a plan view, each of the plurality of pixels may be shaped as a rectangle, a rhombus, or a square. However, the present disclosure is not limited thereto. For example, in a plan view, each of the plurality of pixels may also be shaped as a quadrilateral other than a rectangle, a rhombus, or a square, a polygon other than a quadrilateral, a circle, or an ellipse.

[0064] Since the non-display area NDA does not include pixels, the non-display area NDA may not display an image. The non-display area NDA may be arranged around the display area DA. Figure 1 and Figure 2 As shown in , the non-display area NDA may surround the display area DA. However, the present disclosure is not limited thereto. The display area DA may also be partially surrounded by the non-display area NDA.

[0065] In one or more embodiments, the display device 10 can maintain both the folded state and the unfolded state (e.g., simultaneously).

In addition, even an incomplete folded state (if not an unfolded state) may also be referred to as a folded state. For example, even a folded state at an angle of about 90 degrees or less may be represented as a folded state to distinguish it from an unfolded state, as long as the maximum folding angle is about 90 degrees or more. The radius of curvature when folded may be, but is not limited to, about 5 millimeters (mm) or less, about 1 mm to 2 mm, or about 1.5 mm.

[0067] In one or more embodiments, the display device 10 may include a folding area FDA, a first non-folding area NFA1, and a second non-folding area NFA2. The folding area FDA may be an area in which the display device 10 is folded, and the first non-folding area NFA1 and the second non-folding area NFA2 may be areas in which the display device 10 is not folded.

[0068] The first non-folding area NFA1 may be arranged on one side (eg, the upper side of the folding area FDA). The second non-folding area NFA2 may be arranged on the other side (eg, the lower side of the folding area FDA). The folding area FDA may be a curved area having a set or predetermined curvature.

[0069] In one or more embodiments, the folding area FDA of the display device 10 may be set at a specific position.

[0070] In one or more embodiments, the display device 10 may be foldable in the second direction DR2. Therefore, the length of the display device 10 in the second direction DR2 may be reduced to about half. Therefore, the user can easily carry the display device 10.

[0071] In one or more embodiments, the folding direction of the display device 10 is not limited to the second direction DR2. For example, the display device 10 may also be folded in the first direction DR1. In this case, the length of the display device 10 in the first direction DR1 may be reduced to about half.

[0072] exist Figure 1 and Figure 2 In the embodiment, each of the display area DA and the non-display area NDA overlaps with the folding area FDA, the first non-folding area NFA1, and the second non-folding area NFA2. However, the present disclosure is not limited thereto. For example, each of the display area DA and the non-display area NDA may overlap with at least one of the folding area FDA, the first non-folding area NFA1, or the second non-folding area NFA2.

The rear bonding member may be a pressure-sensitive adhesive member.

[0097] The protection member 310 of the display device 10 will now be described.

[0098] Figure 7 is a schematic cross-sectional view of a protection member 310 according to one or more embodiments. Figure 8 It is a graph showing the light transmittance of heat-resistant PET with respect to wavelength. Fig. 9 is a schematic plan view of a protective member 310 according to one or more embodiments. Fig.10 is a schematic cross-sectional view of a portion of a display device 10 according to one or more embodiments.

[0099] refer to Figure 7 , the protection member 310 according to the present embodiment may include a base layer 311 , a primer layer 312 disposed on the base layer 311 , and an antistatic layer 315 disposed on the primer layer 312 .

[0100] The base layer 311 may support the protective member 310. The base layer 311 may include a polymer film. For example, the polymer film may include at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), polyimide (PI), polyarylate (PAR), polycarbonate (PC), polymethyl methacrylate (PMMA), and cyclic olefin copolymer (COC).

[0101] In one or more embodiments, the base layer 311 may include heat-resistant PET. Heat-resistant PET can be made by a post-heat process to improve the high-temperature deformation of general PET. When non-heat-resistant PET or related art PET is subjected to thermal processing, the oligomers present in the polymer move to the surface, resulting in an increase in haze. Therefore, the optical properties may deteriorate. The heat-resistant PET can have a relatively low haze and a high light transmittance (or transmittance) by removing the oligomers by non-thermal treatment. In one or more embodiments, the heat-resistant PET can have a relatively low thermal shrinkage by a thermal process.

[0102] Figure 8 The transmittance of heat-resistant PET and colored PI with respect to wavelength is shown. Figure 8As shown in , the heat-resistant PET may have a transmittance of about 90% or more in the visible light wavelength range. In one or more embodiments, with respect to other physical properties of the heat-resistant PET, the heat-resistant PET may have a haze of about 2% or less and a glass transition temperature of about 99° C. When exposed to a temperature of about 150° C. for about 30 minutes, the heat-resistant PET may have a heat shrinkage of about 0.2% or less.

[0103] In one or more embodiments, heat-resistant PET having excellent or suitable optical and heat-resistant properties may be utilized as the base layer 311. However, the present disclosure is not limited thereto.

[0104] refer to Figure 5 , Figure 7 and Fig. 9 , the thickness of the base layer 311 may be about 10 μm to about 100 μm. In one or more embodiments, the thickness of the base layer 311 may be about 35 μm to about 75 μm. When the display device 10 is folded / unfolded, the base layer 311 having a thickness within the above range can ensure durability and folding characteristics of the protection member 310.

[0105] The primer layer 312 may be disposed on the base layer 311. The primer layer 312 may exhibit good or appropriate adhesion to the antistatic layer 315 and the base layer 311 to bond the antistatic layer 315 and the base layer 311 together.

[0106] The primer layer 312 may include a binder resin (eg, a heat curing or UV curing resin). Polyurethane resin, polyester resin, and / or polyacrylic resin, etc., can be used as the binder resin.

[0107] The primer layer 312 may be applied on the base layer 311 using a solution process such as coating, dipping, or spraying, and may then be dried or cured.

[0108] The thickness of the primer layer 312 may be about 10 nm to about 300 nm. In an embodiment, the thickness of the primer layer 312 may be about 35 nm to about 100 nm. The primer layer 312 having a thickness within the above range may exhibit excellent or suitable adhesion to the antistatic layer 315 and the base layer 311.

[0109] In addition to the binder resin, the primer layer 312 may further include a filler FIL. The filler FIL may prevent or reduce a reduction in mobility and a dent defect of the protective member 310 during the manufacturing process of the protective member 310. The filler FIL may include barium sulfate, silicon dioxide, or calcium carbonate. In one or more embodiments, the filler FIL may be silicon dioxide.

[0110] The particle size of the filler FIL may be about 0.01 μm to about 2 μm. In one or more embodiments, the particle size of the filler FIL may be about 0.1 μm to about 1 μm. The filler FIL having a particle size within the above range may form (or provide) fine protrusions on the surface of the protective member 310, thereby preventing or reducing the reduction in mobility and dent defects of the protective member 310.

[0111] The filler FIL may be included in an amount of about 0.01% to about 80% by weight based on 100% of the total weight of the primer layer 312. In one or more embodiments, the filler FIL may be included in an amount of about 0.1% to about 50% by weight based on 100% of the total weight of the primer layer 312. The filler FIL included in the primer layer 312 in an amount within the above range can ensure the workability of the primer layer 312 and reduce the surface friction coefficient of the protective member 310.

[0112] Filler FIL can be covered by primer layer 312 and dispersed in primer layer 312.For example, filler FIL can be arranged in primer layer 312 inside, and does not protrude outside the surface of primer layer 312. The binder resin of primer layer 312 can cover the whole surface of filler FIL.Therefore, the surface of primer layer 312 can have the projection formed in the region overlapping with filler FIL and the depression formed in the region not overlapping with filler FIL.For example, the surface of primer layer 312 can have irregularity.

[0113] Some filler FILs may contact the surface of the base layer 311, and other filler FILs may be spaced apart from the surface of the base layer 311. However, the present disclosure is not limited thereto, and all filler FILs may contact the surface of the base layer 311, or all filler FILs may not contact the surface of the base layer 311.

[0114] The antistatic layer 315 may be disposed on the primer layer 312. The antistatic layer 315 can prevent or reduce static electricity generated within the protection member 310. The antistatic layer 315 may be formed along an irregular surface of the primer layer 312 to be uneven.

[0115] The antistatic layer 315 may include a binder resin and an antistatic agent.

[0116] The binder resin of the antistatic layer 315 can be water-soluble or water-insoluble (organic solvent type or kind). For example, a polymer compound having one or more functional groups selected from acrylic acid groups, polyurethane groups, epoxy groups, amide groups, hydroxyl groups and silane groups can be used alone, or two or more polymer compounds can be used in combination. For example, the binder resin can use (but is not limited to) one or more of acrylic acid resins, polyurethanes, polyepoxy resins, polyamides, polyester resins, vinyl acetate, polysiloxanes and copolymers thereof.

[0117] The antistatic agent is not particularly limited as long as it has antistatic properties. However, the antistatic agent may utilize, for example, one or more of a conductive polymer, a metal salt having a metal ion, an ionic liquid, a carbon material, and a surfactant.

[0118] The conductive polymer may utilize one or more of polyethylenedioxythiophene (PEDOT), polyacetylene, polyparaphenylene vinylene, polyparaphenylene resin, polythiopheneethylene, polythiophene, polyaniline, polyisothiophene, polypyrrole, and polyphenylene dimethyl sulfide.

[0119] Examples of metal salts may include lithium salts, lithium imines, lithium amides and potassium salts. Examples of ionic liquids may include pyridine imines. Carbon materials may be, for example, one or more of carbon black, graphite, graphene, carbon nanotubes (CNTs) and carbon nanofibers (CNFs). Examples of surfactants may include sulfonates, quaternary ammonium salts and lauryl dimethyl benzyl ammonium salts.

[0120] The antistatic layer 315 may be coated by a solution process such as gravure coating, commaknife coating, roll coating, or spray coating, but the present disclosure is not limited thereto.

[0121] The thickness of the antistatic layer 315 may be about 10 nm to about 1000 nm. In one or more embodiments, the thickness of the antistatic layer 315 may be about 80 nm to about 200 nm. The antistatic layer 315 having a thickness within the above range can ensure coating properties and improve antistatic performance.

[0122] The thickness of the antistatic layer 315 may be smaller than the particle size of the filler FIL. For example, the lowermost surface of the antistatic layer 315 may be located lower than the uppermost portion of each filler FIL. The lowermost surface of the antistatic layer 315 may be arranged to be closer to the upper surface of the base layer 311 than the uppermost portion of each filler FIL.

[0123] As described above, the protection member 310 may include the base layer 311 , the primer layer 312 , and the antistatic layer 315 .

[0124] In one or more embodiments, the thickness of the primer layer 312 and the thickness of the antistatic layer 315 can be less than the particle size of the filler FIL, so that irregularities can be formed on the surface of the protective member 310. The thickness of the primer layer 312 can be less than the particle size of the filler FIL, and the thickness of the antistatic layer 315 can be less than the particle size of the filler FIL. In one or more embodiments, the thickness of the primer layer 312 and the thickness of the antistatic layer 315 can be less than the particle size of the filler FIL. Therefore, even if the primer layer 312 and the antistatic layer 315 cover the filler FIL, because the particle size of the filler FIL is greater than the thickness of the primer layer 312 and the thickness of the antistatic layer 315, the surface of the protective member 310 can also form irregularities.

[0125] In the protective member 310, the filler FIL may be dispersed in the primer layer 312 to reduce the surface friction coefficient of the protective member 310. In this case, the ratio of the area occupied by the filler FIL to the total area of ​​the protective member 310 may be about 1.5% to about 2%. When the ratio of the area occupied by the filler FIL to the total area of ​​the protective member 310 is within the above range, the surface friction coefficient of the protective member 310 can be reduced while ensuring the manufacturability of the protective member 310.

[0126] Because irregularities are formed on the surface of the protective member 310 due to the filler FIL included in the primer layer 312, the surface friction coefficient of the protective member 310 can be reduced. In one or more embodiments, the surface friction coefficient of the protective member 310 may be about 0.320 to about 0.451. Here, the surface of the protective member 310 refers to the surface of the antistatic layer 315. Within the above range, the protective member 310 having a surface friction coefficient can improve mobility during the manufacturing process of the protective member 310.

[0127] For example, the protective member 310 may be attached to the lower surface of the display panel 100. The protective member 310 and the display panel 100 may be attached to each other through an alignment process. In the process of moving and aligning the protective member 310 while fixing the display panel 100, if the surface friction coefficient of the protective member 310 is small, the degree of movement of the protective member 310 is good (i.e., the mobility is improved). Therefore, the alignment process can be easily performed. Therefore, in the current embodiment, the protective member 310 may be formed to have a surface friction coefficient of about 0.320 to about 0.451. Therefore, the mobility of the protective member 310 can be improved, thereby facilitating the alignment process of the protective member 310 with the display panel 100.

[0128] refer to Fig.10, the protective member 310 may be disposed under the display panel 100, and the cushion layer 320 may be disposed under the protective member 310. The first bonding member PSA1 may be disposed between the protective member 310 and the display panel 100 to bond the protective member 310 and the display panel 100 together. The second bonding member PSA2 may be disposed between the protective member 310 and the cushion layer 320 to bond the protective member 310 and the cushion layer 320 together.

[0129] like Figure 7 The structure of the protective member 310 shown in FIG. 1 may be inverted and then bonded to the display panel 100. For example, the base layer 311 of the protective member 310 may be placed facing the lower surface of the display panel 100, and the antistatic layer 315 of the protective member 310 may be placed facing the cushion layer 320. The first bonding member PSA1 may contact the lower surface of the display panel 100 and the base layer 311 of the protective member 310 to bond them together. The second bonding member PSA2 may contact the antistatic layer 315 of the protective member 310 and the cushion layer 320 to bond them together.

[0130] Fig.11 is a schematic cross-sectional view of a protection member 310 according to one or more embodiments. Fig.12 is based on Fig.11 Schematic plan view of a protective member 310 of an embodiment. Fig.13 is a schematic cross-sectional view of a portion of a display device 10 according to one or more embodiments.

[0131] refer to Figures 11 to 13 , the current embodiment is different from the above Figures 7 to 10 The embodiment of the present invention is different in that the base layer 311 includes a filler FIL. Therefore, the same elements as those of the above-described embodiment will be briefly described, and the differences will be mainly described below.

[0132] The protection member 310 according to the present embodiment may include a base layer 311 , a primer layer 312 disposed on the base layer 311 , and an antistatic layer 315 disposed on the primer layer 312 .

[0133] The base layer 311 may support the protective member 310. The base layer 311 may include a polymer film. The polymer film may include, for example, at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), polyimide (PI), polyarylate (PAR), polycarbonate (PC), polymethyl methacrylate (PMMA), and cyclic olefin copolymer (COC). In one or more embodiments, the base layer 311 may include general PET.

[0134] The base layer 311 may include a filler FIL. The filler FIL may prevent or reduce a decrease in mobility and a dent defect of the protective member 310 in a manufacturing process of the protective member 310. The filler FIL may include barium sulfate, silicon dioxide, or calcium carbonate. In one or more embodiments, the filler FIL may be silicon dioxide.

[0135] The particle size of the filler FIL may be about 0.01 μm to about 2 μm. In one or more embodiments, the particle size of the filler FIL may be about 0.1 μm to about 1 μm. The filler FIL having a particle size within the above range may form (or provide) fine protrusions on the surface of the protective member 310, thereby preventing or reducing the reduction in mobility and dent defects of the protective member 310.

[0136] The filler FIL may be included in an amount of about 0.01% to about 80% by weight based on 100% of the total weight of the base layer 311. In one or more embodiments, the filler FIL may be included in an amount of about 0.1% to about 50% by weight based on 100% of the total weight of the base layer 311. The filler FIL included in the base layer 311 in an amount within the above range can ensure the workability of the base layer 311 and reduce the surface friction coefficient of the protective member 310.

[0137] The filler FIL may be dispersed in the base layer 311. For example, the filler FIL may be arranged in the base layer 311 without protruding outside the surface of the base layer 311. In one or more embodiments, the resin of the base layer 311 may cover the entire surface of the filler FIL. Therefore, the surface of the base layer 311 may have protrusions formed in the area overlapping with the filler FIL and depressions formed in the area not overlapping with the filler FIL. For example, the surface of the base layer 311 may have irregularities.

[0138] The primer layer 312 may be disposed on the base layer 311. The primer layer 312 may exhibit good or appropriate adhesion to the antistatic layer 315 and the base layer 311 to bond them together.

[0139] The thickness of the primer layer 312 can be Figure 7 . For example, the thickness of the primer layer 312 may be about 10 nm to about 300 nm. The primer layer 312 having a thickness within the above range may exhibit excellent or suitable adhesion to the antistatic layer 315 and the base layer 311, and irregularities formed on the base layer 311 may be formed on the surface of the primer layer 312.

[0140] The surface of the primer layer 312 may have irregularities corresponding to the irregularities of the base layer 311 formed by the filler FIL. Therefore, the surface of the primer layer 312 may have protrusions formed in a region overlapping with the filler FIL and recesses formed in a region not overlapping with the filler FIL.

[0141] The antistatic layer 315 may be disposed on the primer layer 312. The antistatic layer 315 can prevent or reduce static electricity generated in the protection member 310. The antistatic layer 315 may have protrusions PRU formed along irregularities of the primer layer 312.

[0142] The protrusions PRU may be arranged on the surface of the antistatic layer 315 and may be spaced apart from each other. In one or more embodiments, the protrusions PRU may be randomly arranged. In one or more embodiments, the protective member 310 may include a protrusion PRU arranged on a surface (e.g., arranged on the surface of the antistatic layer 315). The protrusions PRU may be formed by the irregularities of the base layer 311 formed by the filler FIL and the irregularities of the primer layer 312 formed to cover the irregularities of the base layer 311. Therefore, the protrusions PRU may overlap with the filler FIL of the base layer 311, and the area other than the protrusions PRU may not overlap with the filler FIL.

[0143] The surface friction coefficient of the protection member 310 can be reduced by forming the protrusions PRU on the surface. In this case, the ratio of the area occupied by the filler FIL to the total area of ​​the protection member 310 can be about 1.5% to about 2%. When the ratio of the area occupied by the filler FIL to the total area of ​​the protection member 310 is within the above range, the surface friction coefficient of the protection member 310 can be reduced while ensuring the manufacturability of the protection member 310.

[0144] The surface friction coefficient of the protective member 310 may be about 0.320 to about 0.451. Here, the surface of the protective member 310 refers to the surface of the antistatic layer 315. The protective member 310 having a surface friction coefficient within the above range can improve mobility during the manufacturing process of the protective member 310.

[0145] refer to Fig.13 , the protective member 310 may be disposed under the display panel 100, and the cushion layer 320 may be disposed under the protective member 310. The first bonding member PSA1 may be disposed between the protective member 310 and the display panel 100 to bond the protective member 310 and the display panel 100 together. The second bonding member PSA2 may be disposed between the protective member 310 and the cushion layer 320 to bond the protective member 310 and the cushion layer 320 together.

[0146] like Fig.11The structure of the protective member 310 shown in FIG. 1 may be inverted and then bonded to the display panel 100. For example, the base layer 311 of the protective member 310 may be placed to face the lower surface of the display panel 100, and the antistatic layer 315 of the protective member 310 may be placed to face the cushion layer 320. The first bonding member PSA1 may contact the lower surface of the display panel 100 and the base layer 311 of the protective member 310 to bond them together. The second bonding member PSA2 may contact the antistatic layer 315 of the protective member 310 and the cushion layer 320 to bond them together.

[0147] Hereinafter, experiments conducted on the protection member 310 according to the above-described embodiment will be described.

[0148] Preparation of multiple protection component samples

[0149] Comparison Examples

[0150] A primer layer having a thickness of 50 nm is applied on a heat-resistant PET having a thickness of 50 μm. The primer layer is formed by mixing 10% by weight of silica particles having a particle size of about 300 nm with a polyester resin (e.g., 90% by weight). An antistatic layer having a thickness of about 600 nm is formed on the primer layer. The antistatic layer is formed by mixing 10% by weight of silica particles having a particle size of about 2 μm with a polyurethane resin (e.g., 90% by weight) mixed with an antistatic agent.

[0151] Example

[0152] A protective member according to Example was produced under the same conditions as those of Comparative Example, except that an antistatic layer having a thickness of 100 nm but not including silica particles was formed.

[0153] Experimental Example 1: Measurement of the surface friction coefficient of the protective member

[0154] The surface friction coefficient of 17 protective member samples made according to the comparative example and the example was measured. Here, the surface refers to the surface of the antistatic layer of the protective member. The surface friction coefficient was measured using a universal mechanical tester (UMT) of Bruker, and the measurement conditions were a load of 5N, a speed of about 300 mm / min, a reciprocating motion of about 40 mm, and a duration of about 80 seconds.

[0155] The results are shown in Table 1 and Fig.14 Table 1 shows the results of measuring the surface friction coefficients of the samples of the protective members of the comparative example and the example. Fig.14 : is a graph showing the surface friction coefficients of the protection member samples of the comparative example and the example according to the experimental example 1.

[0156] Table 1

[0157]

[0158] Refer to Table 1 and Fig.14 , an average value of the surface friction coefficient of the protection member samples according to the comparative example was about 1.17, and an average value of the surface friction coefficient of the protection member samples according to the example was about 0.39.

[0159] As is apparent from these results, the surface friction coefficient of the protection member according to the example is significantly reduced within a range of about 0.320 to about 0.454.

[0160] Experimental Example 2: Measuring the surface quality of protective components

[0161] The surface quality (Kc) values ​​of 18 protective member samples made according to the comparative example and the example were measured. The measuring instrument used was Optimap of the RHOPOINT instrument. The Kc value is a value obtained by quantifying the surface quality and a value measured using Optimap. The more uneven the measured surface is due to texture, flatness, number of defects, size and / or shape, etc., the greater the Kc value. The flatter the surface, the smaller the Kc value.

[0162] The results are shown in Fig.15 and Fig.16 middle. Fig.15 is a graph showing Kc values ​​of protection member samples according to the example of Experimental Example 2. Fig.16 is a diagram showing an Optimap image of a protective member sample according to an example of Experimental Example 2.

[0163] refer to Fig.15 and Fig.16 , the average Kc value of the protection member samples according to the comparative example was about 0.82, and the average Kc value of the protection member samples according to the example was about 0.36.

[0164] It is apparent from these results that the surface quality of the protective member according to the example is improved. Experimental Example 3: Detection of Defect Rate of Protective Member

[0165] Each of the multiple protective members in the comparative example and the example is attached to the display panel, and then the dent defect and the foreign matter defect are detected using Optimap. The results are shown in Table 2. In Table 2, the number refers to the number of display panels to which the protective member is attached, and the first to third rounds refer to the inspection rounds (here, different display panels are inspected in the first to third rounds). In one or more embodiments, the improvement aspect refers to the improvement rate of the example compared with the comparative example.

[0166] Table 2

[0167]

[0168]

[0169] Referring to Table 2, the protection member according to the example improves about 58% of the dent defect and about 27% of the foreign matter defect, compared with the protection member according to the comparative example.

[0170] As is apparent from these results, the protection member according to the example can improve the dent defect and the foreign matter defect.

[0171] In the display device according to one or more embodiments, defects and surface quality of a protection member attached to a lower surface of a display panel can be improved by reducing a surface friction coefficient of the protection member.
