[0025] In one embodiment, the first thickness of the first refractive layer may be about 70 nm to about 120 nm.

[0026] To achieve another objective of the present invention as described above, an electronic device according to an embodiment of the present invention includes: a power module; and a display device, powered by the power module, including a display panel and a window module disposed on the display panel. The window module includes: a substrate; an anti-fingerprint layer disposed on the substrate; and an anti-reflective layer disposed between the substrate and the anti-fingerprint layer. The anti-reflective layer includes: a first refractive layer disposed below the anti-fingerprint layer; a second refractive layer disposed below the first refractive layer, having a second thickness greater than or equal to a first thickness multiplied by approximately 0.4 and less than or equal to a first thickness multiplied by approximately 1.5; and a third refractive layer, disposed in cross-section between the second refractive layer and the substrate, having a refractive index greater than that of the first refractive layer, and a thickness of approximately 100 nm or more.

The same reference numerals are used for the same components in the drawings, and repeated descriptions of the same components are omitted.

[0053] Figure 1 This is a perspective view showing a display device according to an embodiment of the present invention. Figure 2 It is shown Figure 1 An exploded perspective view of the display device. Figure 3 It is shown Figure 1 A cross-sectional view of a portion of the display device in the planar area.

[0054] In this specification, a plane can be defined by a first direction DR1 and a second direction DR2 intersecting the first direction DR1. For example, the second direction DR2 can be perpendicular to the first direction DR1. Additionally, a third direction DR3 can be the normal direction of the plane. That is, the third direction DR3 can be perpendicular to the plane formed by the first direction DR1 and the second direction DR2.

[0055] Reference Figures 1 to 3According to an embodiment of the present invention, a display device DD may include a planar region PA and a curved region CA. The curved region CA may have a predetermined curvature and bend from one side of the planar region PA. For example, the curved region CA may bend from one side of the planar region PA in the opposite direction to a third direction DR3. In one embodiment, a portion of the display device DD adjacent to the edge of the planar region PA and facing outward may be defined as the curved region CA. However, the bending direction of the curved region CA according to an embodiment of the present invention is not necessarily limited to this.

[0056] The display device DD may include a display panel DP, an adhesive layer AD, and a window module WM. The window module WM may include a substrate BS, an anti-reflective layer AR, and an anti-fingerprint layer AF. The display device DD includes a planar area PA and a curved area CA, therefore the display panel DP and the window module WM may also include a planar area PA and a curved area CA.

[0057] The display panel DP can emit light to display images. For example, the display panel DP may include multiple pixels that emit light. The pixels may be located in a planar region PA of the display device DD. For example, the pixels may be arranged in a matrix in the planar region PA along a first direction DR1 and a second direction DR2. However, the array of pixels according to embodiments of the present invention is not necessarily limited to this, and the pixels may also be configured in a curved region CA.

[0058] The window module (WM) can be configured on the display panel (DP). For example, the window module (WM) can be configured in the planar area (PA) and the curved area (CA).

[0059] The substrate BS can be disposed on the display panel DP. In one embodiment, the substrate BS may include glass, quartz, plastic, etc. For example, the plastic included in the substrate BS may include polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalene (PEN), polypropylene (PP), polycarbonate (PC), polystyrene (PS), polysulfone (PSul), polyethylene (PE), polyphthalamide (PPA), polyethersulfone (PES), polyarylate (PAR), polycarbonate oxide (PCO), modified polyphenylene oxide (MPPO), etc. These can be used alone or in combination with each other. However, the materials included in the substrate BS according to embodiments of the present invention are not necessarily limited thereto, and the substrate BS may include materials having various kinds of optical transparency that can provide an image provided from the display panel DP of the display device DD to the user.

[0060] An adhesive layer AD can be disposed between a display panel DP and a substrate BS. In one embodiment, the adhesive layer AD may include an adhesive material. For example, the adhesive layer AD can bond the display panel DP and the window module WM together. In one embodiment, the adhesive layer AD may include a pressure-sensitive adhesive (PSA), an optically clear adhesive (OCA), an optically clear resin (OCR), etc. These can be used individually or in combination with each other.

[0061] An anti-reflective layer AR can be disposed on a substrate BS. The anti-reflective layer AR reduces the reflectivity of light reflected at the surface of the display device DD. For example, the anti-reflective layer AR can be composed of alternating layers with different refractive indices to guide the incident and reflected light to cancel each other out. Thus, the anti-reflective layer AR reduces the reflection of external light to prevent glare for the user of the display device DD.

[0062] The anti-fingerprint layer AF can be disposed on the anti-reflective layer AR. In one embodiment, the anti-fingerprint layer AF may include a fingerprint-resistant material. For example, the fingerprint-resistant material may include titanium oxide (TiO2). X Metal oxides, silicon compounds, fluorine compounds, etc., are used. These can be used alone or in combination. However, the fingerprint-resistant material included in the anti-fingerprint layer AF according to embodiments of the present invention is not necessarily limited to this.

[0063] In one embodiment, the anti-fingerprint layer AF can be formed by coating the fingerprint-resistant material onto the anti-reflective layer AR. For example, the coating method of the anti-fingerprint layer AF may include a wet coating method or a dry coating method. However, the manufacturing method of the anti-fingerprint layer AF according to embodiments of the present invention is not necessarily limited thereto.

[0064] Furthermore, the structure of the window module WM according to embodiments of the present invention is not necessarily limited to this; the window module WM may also include a hard coating layer disposed between the substrate BS and the anti-reflective layer AR. For example, the hard coating layer may include a photocurable resin and microparticles dispersed in the photocurable resin.

[0065] Figure 4 It shows along Figure 2 A cross-sectional view of the window module intercepted by the I-I' line. Figure 5 It shows along Figure 2 A cross-sectional view of the anti-reflective layer taken by the I-I' line.

[0066] Reference Figure 4 as well as Figure 5 A portion of the window module WM located in the planar region PA can be substantially flat. Additionally, a portion of the window module WM located in the curved region CA can extend from the portion of the window module WM located in the planar region PA and bend in the opposite direction to DR3. Since the window module WM includes an anti-reflective layer AR, the anti-reflective layer AR can have substantially the same cross-sectional structure as the window module WM. For example, a portion of the anti-reflective layer AR located in the planar region PA can be substantially flat. Additionally, a portion of the anti-reflective layer AR located in the curved region CA can extend from the portion of the anti-reflective layer AR located in the planar region PA and bend in the opposite direction to DR3.

[0067] In one embodiment, the thickness of the antireflective layer AR located in the planar region PA, i.e., the first thickness T1, can be substantially the same across the planar region PA. For example, the antireflective layer AR in the planar region PA can be formed to have a substantially uniform thickness. The thickness of the antireflective layer AR located in the curved region CA can vary. For example, the thickness of the antireflective layer AR, i.e., the second thickness T2, can decrease as one moves from the boundary between the planar region PA and the curved region CA towards the curved region CA. Specifically, since the substrate BS is bent in the curved region CA, the second thickness T2 of the antireflective layer AR formed in the curved region CA on the substrate BS can be less than the first thickness T1 of the antireflective layer AR formed in the planar region PA on the substrate BS. In one embodiment, the first thickness T1 can be greater than the second thickness T2. However, the relationship between the first thickness T1 and the second thickness T2 according to embodiments of the present invention is not necessarily limited thereto, and the relationship between the first thickness T1 and the second thickness T2 can become varied depending on the curvature, bending direction, etc., of the curved region CA.

[0068] In one embodiment, the second thickness T2 can be defined according to the following [Mathematical Formula 1].

[0069] [Mathematical Expression 1] T2=T1×cosθ Here, θ is the angle formed by the first extension surface S1 and the second extension surface S2.

[0070] Specifically, the first extension surface S1 can be a plane parallel to the normal direction of one side of the anti-reflective layer AR located in the planar region PA. Additionally, the second extension surface S2 can be a plane parallel to the normal direction of one side of the anti-reflective layer AR located in the curved region CA.

[0071] As a portion of the anti-reflective layer AR bends within the curved region CA, when the anti-reflective layer AR is formed on the substrate BS, the second thickness T2 of the anti-reflective layer AR in the curved region CA is reduced compared to the first thickness T1 of the anti-reflective layer AR in the planar region PA. This may result in a path difference between the light recognized in the curved region CA and the light recognized in the planar region PA. Consequently, a chromatic aberration may occur between the light recognized in the planar region PA and the light recognized in the curved region CA.

[0072] Figure 6 It is shown Figure 2 A cross-sectional view of a portion of a form module.

[0073] Reference Figure 6 In cross-section, the anti-reflective layer AR can be disposed between the substrate BS and the anti-fingerprint layer AF. In one embodiment, the reflectivity of light reflected at the surface of the window module WM can be less than about 0.6%.

[0074] The anti-reflective layer AR may include a first refractive layer L1, a second refractive layer L2, a third refractive layer L3, a fourth refractive layer L4, a fifth refractive layer L5, a sixth refractive layer L6, a seventh refractive layer L7, an eighth refractive layer L8, and a ninth refractive layer L9. In this specification, the first refractive layer L1 may be referred to as the first refractive layer, the second refractive layer L2 as the second refractive layer, the eighth refractive layer L8 as the third refractive layer, the fifth refractive layer L5 as the fourth refractive layer, and the ninth refractive layer L9 as the fifth refractive layer.

[0075] In one embodiment, the antireflective layer AR can have a structure in which low-refractive-index layers with relatively low refractive indices and high-refractive-index layers are stacked alternately. For example, the first refractive layer L1, the third refractive layer L3, the fifth refractive layer L5, the seventh refractive layer L7, and the ninth refractive layer L9 can each be the low-refractive-index layer. Conversely, the second refractive layer L2, the fourth refractive layer L4, the sixth refractive layer L6, and the eighth refractive layer L8 can each be the high-refractive-index layer.

[0076] In one embodiment, the first refractive layer L1, the third refractive layer L3, the fifth refractive layer L5, the seventh refractive layer L7, and the ninth refractive layer L9 each have a refractive index of about 1.8 or less based on a wavelength of 550 nm. Preferably, the first refractive layer L1, the third refractive layer L3, the fifth refractive layer L5, the seventh refractive layer L7, and the ninth refractive layer L9 each have a refractive index of about 1.35 to about 1.8 based on a wavelength of 550 nm.

[0077] In one embodiment, the second refractive layer L2, the fourth refractive layer L4, the sixth refractive layer L6, and the eighth refractive layer L8 each have a refractive index of about 1.9 or more based on a wavelength of 550 nm. Preferably, the second refractive layer L2, the fourth refractive layer L4, the sixth refractive layer L6, and the eighth refractive layer L8 each have a refractive index of about 1.9 to about 2.5 based on a wavelength of 550 nm.

[0078] In one embodiment, the first refractive layer L1, the third refractive layer L3, the fifth refractive layer L5, the seventh refractive layer L7, and the ninth refractive layer L9 may each comprise silicon oxide (SiO2). x Examples include silicon oxide (SiO2) and silicon oxynitrides (SiON). These can be used alone or in combination. In one embodiment, silicon oxide (SiO2) is included. x The refractive index of the low-refractive layer can be less than that of the low-refractive layer including silicon oxynitride (SiON). However, the materials included in the first refractive layer L1, the third refractive layer L3, the fifth refractive layer L5, the seventh refractive layer L7, and the ninth refractive layer L9 according to embodiments of the present invention are not necessarily limited thereto.

[0079] In one embodiment, the second refractive layer L2, the fourth refractive layer L4, the sixth refractive layer L6, and the eighth refractive layer L8 may each comprise silicon nitride (SiN). x However, the materials included in the second refractive layer L2, the fourth refractive layer L4, the sixth refractive layer L6, and the eighth refractive layer L8 according to embodiments of the present invention are not necessarily limited thereto.

[0080] The first refractive layer L1 can be disposed below the anti-fingerprint layer AF. In one embodiment, the first thickness TH1 of the first refractive layer L1 can be about 70 nm to about 120 nm.

[0081] The second refractive layer L2 may be disposed below the first refractive layer L1. In one embodiment, the second thickness TH2 of the second refractive layer L2 may be less than the first thickness TH1 of the first refractive layer L1. For example, the second thickness TH2 may be greater than the value of the first thickness TH1 multiplied by 0.4 and less than the first thickness TH1.

[0082] The third refractive layer L3 can be disposed below the second refractive layer L2. The fourth refractive layer L4 can be disposed below the third refractive layer L3. In one embodiment, the thickness of the third refractive layer L3 can be less than the second thickness TH2 of the second refractive layer L2.

[0083] The fifth refractive layer L5 can be disposed below the fourth refractive layer L4. In one embodiment, the third thickness TH3 of the fifth refractive layer L5 can be about 50 nm or more.

[0084] The sixth refractive layer L6 can be disposed below the fifth refractive layer L5. In one embodiment, the thickness of the sixth refractive layer L6 can be less than the third thickness TH3 of the fifth refractive layer L5.

[0085] The seventh refractive layer L7 can be disposed below the sixth refractive layer L6. The eighth refractive layer L8 can be disposed below the seventh refractive layer L7. In one embodiment, the fourth thickness TH4 of the eighth refractive layer L8 can be about 100 nm or more.

[0086] In one embodiment, the fourth thickness TH4 of the eighth refractive layer L8 can be greater than the thickness of each of the second refractive layer L2, the fourth refractive layer L4, and the sixth refractive layer L6. In other words, the fourth thickness TH4 of the eighth refractive layer L8 can have the largest value among the thicknesses of the high-refractive layers included in the anti-reflective layer AR.

[0087] The ninth refractive layer L9 can be disposed below the eighth refractive layer L8. In one embodiment, the fifth thickness TH5 of the ninth refractive layer L9 can be about 20 nm or more. In one embodiment, the ninth refractive layer L9 can have a monolayer structure formed by a low-refractive layer.

[0088] As previously mentioned, in the window module WM, the anti-reflective layer AR can have a structure with alternating layers of low-refractive and high-refractive layers. Furthermore, the first thickness TH1 of the topmost low-refractive layer, the first refractive layer L1, can be approximately 70 nm to approximately 120 nm. Additionally, the second thickness TH2 of the high-refractive layer L2, disposed below the first refractive layer L1, can be greater than the value of multiplying the first thickness TH1 of the first refractive layer L1 by 0.4, but less than the first thickness TH1. Furthermore, the third thickness TH3 of the third low-refractive layer (the fifth refractive layer L5) included in the low-refractive layer AR can be approximately 50 nm or more. Furthermore, the fourth thickness TH4 of the bottommost high-refractive layer (the eighth refractive layer L8) included in the high-refractive layer AR can be the largest among the high-refractive layers. Furthermore, the fifth thickness TH5 of the bottommost ninth refractive layer L9 included in the low-refractive layer AR can be approximately 20 nm or more. This reduces the area PA (see reference) in the planar region of the window module WM. Figure 4 The light identified in the window module WM and the curved surface region CA (refer to) Figure 4 This reduces the color difference between the lights identified in the module. Additionally, it can reduce the reflectivity of light reflected at the surface of the window module WM.

[0089] In addition, Figure 1 The display device DD includes a window module WM, which can reduce surface reflectivity and provide users with images of improved display quality.

[0108] Reference Figure 8 The described form module WMa can be compared with the reference Figure 6 The window modules WM described herein have substantially the same or similar structures to each other, except for differences in the structure of the ninth refractive layer L9a. Further details may be omitted or briefly described below. Figure 6 The description repeats the content of the WM form module.

[0109] Reference Figure 8The window module WMa may include an anti-reflective layer ARa. The anti-reflective layer ARa may include a ninth refractive layer L9a. In one embodiment, the ninth refractive layer L9a may have a multilayer structure formed by multiple low-refractive layers. For example, the ninth refractive layer L9a may include a first sub-refractive layer L9-1a, a second sub-refractive layer L9-2a, a third sub-refractive layer L9-3a, and a fourth sub-refractive layer L9-4a.

[0110] In one embodiment, the first sub-refractive layer L9-1a, the second sub-refractive layer L9-2a, the third sub-refractive layer L9-3a, and the fourth sub-refractive layer L9-4a may each be the low-refractive layer. For example, the first sub-refractive layer L9-1a, the second sub-refractive layer L9-2a, the third sub-refractive layer L9-3a, and the fourth sub-refractive layer L9-4a may each comprise silicon oxide (SiO2). x ), silicon oxynitrides (SiON), etc. These can be used alone or in combination with each other.

[0111] In one embodiment, the first sub-refractive layer L9-1a and the third sub-refractive layer L9-3a may comprise the same material as each other. For example, the first sub-refractive layer L9-1a and the third sub-refractive layer L9-3a may comprise silicon oxynitride (SiON).

[0112] In one embodiment, the second sub-refractive layer L9-2a and the fourth sub-refractive layer L9-4a may comprise the same material as each other. For example, the second sub-refractive layer L9-2a and the fourth sub-refractive layer L9-4a may comprise silicon oxide (SiO2). x ).

[0113] In one embodiment, the first sub-refractive layer L9-1a may include a material different from the second sub-refractive layer L9-2a. In one embodiment, the second sub-refractive layer L9-2a may include a material different from the third sub-refractive layer L9-3a. In one embodiment, the third sub-refractive layer L9-3a may include a material different from the fourth sub-refractive layer L9-4a.

[0114] In one embodiment, the refractive index of the first sub-refractive layer L9-1a may be greater than the refractive index of the second sub-refractive layer L9-2a. In one embodiment, the refractive index of the second sub-refractive layer L9-2a may be less than the refractive index of the third sub-refractive layer L9-3a. In one embodiment, the refractive index of the third sub-refractive layer L9-3a may be greater than the refractive index of the fourth sub-refractive layer L9-4a.

[0115] As previously mentioned, in the window module WMa, the anti-reflective layer ARa can have a structure with alternating layers of low-refractive and high-refractive layers. Furthermore, the first thickness of the uppermost low-refractive layer, the first refractive layer L1, located in the anti-reflective layer ARa, can be approximately 70 nm to approximately 120 nm. Additionally, the second thickness of the high-refractive layer L2, disposed below the first refractive layer L1, can be greater than the value of multiplying the first thickness of the first refractive layer L1 by 0.4 and less than the first thickness. Furthermore, the third thickness of the fifth refractive layer L5, the third low-refractive layer from the top of the anti-reflective layer ARa, can be approximately 50 nm or more. Furthermore, the fourth thickness of the eighth refractive layer L8, the lowermost high-refractive layer in the anti-reflective layer ARa, can be the largest among the high-refractive layers. Finally, the thickness of the ninth refractive layer L9a, the lowermost low-refractive layer in the anti-reflective layer ARa, can be approximately 20 nm or more. This reduces the planar area PA of the window module WMa (see reference). Figure 4 The light identified in the window module WMa and the curved area CA (refer to) Figure 4 This reduces the color difference between the lights identified in the model. Additionally, it can reduce the reflectivity of light reflected at the surface of the window module WMa.

[0116] Furthermore, the ninth refractive layer L9a can have a multilayer structure with multiple low-refractive layers stacked on top of each other. Therefore, Figure 8 The fifth thickness of the ninth refractive layer L9a can be greater than Figure 6 The fifth thickness TH5 of the ninth refractive layer L9. Therefore, the durability of the window module WMa, which includes the ninth refractive layer L9a, can be further improved.

[0122] In one embodiment, the thickness of the dummy structure DS (e.g., the sum of the thicknesses of the first dummy layer DL1 and the second dummy layer DL2) may be less than the thickness of each of the first refractive layer L1, the second refractive layer L2, the third refractive layer L3, the fourth refractive layer L4, the fifth refractive layer L5, the sixth refractive layer L6, the seventh refractive layer L7, the eighth refractive layer L8, and the ninth refractive layer L9. In one embodiment, the thicknesses of the first dummy layer DL1 and the second dummy layer DL2 may be the same. However, the thicknesses of the first dummy layer DL1 and the second dummy layer DL2 according to embodiments of the present invention are not necessarily limited thereto.

[0123] As previously mentioned, in the window module WMb, the antireflective layer ARb can have a structure with alternating layers of low-refractive and high-refractive layers. Furthermore, the first thickness of the uppermost low-refractive layer, the first refractive layer L1, located in the antireflective layer ARb, can be approximately 70 nm to approximately 120 nm. Additionally, the second thickness of the high-refractive layer, the second refractive layer L2, disposed below the first refractive layer L1, can be greater than the value of multiplying the first thickness of the first refractive layer L1 by 0.4 and less than the first thickness. Furthermore, the third thickness of the fifth refractive layer L5, the third low-refractive layer from the uppermost point of the antireflective layer ARb, can be approximately 50 nm or more. Furthermore, the fourth thickness of the eighth refractive layer L8, the lowermost high-refractive layer in the antireflective layer ARb, can be the largest among the high-refractive layers. Furthermore, the fifth thickness of the ninth refractive layer L9, the lowermost low-refractive layer in the antireflective layer ARb, can be approximately 20 nm or more. This reduces the planar area PA of the window module WMb (see reference). Figure 4 The light identified in the window module WMb and the curved area CA (refer to) Figure 4 This reduces the color difference between the light sources identified in the model. Additionally, it can reduce the reflectivity of light reflected at the surface of the window module WMb.

[0124] Additionally, the window module WMb may also include a virtual structure DS disposed below the ninth refractive layer L9 and stacked with a low-refractive layer and a high-refractive layer. Thus, Figure 9 The total thickness of the anti-reflective layer ARb can be greater than Figure 6 The thickness of the anti-reflective layer AR is increased. Therefore, the durability of the window module WMb, which includes the anti-reflective layer ARb, can be improved.

Furthermore, the fifth thickness of the ninth refractive layer L9, the lowermost low-refractive layer in the antireflective layer Are, can be approximately 20 nm or more. This reduces the area PA (see reference) in the planar region of the window module WMe.

For example, the fourth sub-dummy layer DL4-4f can include silicon oxide (SiO2). x ), silicon oxynitrides (SiON), etc.

[0161] In one embodiment, the first sub-dummy layer DL4-1f and the third sub-dummy layer DL4-3f may comprise the same material as each other. In one embodiment, the second sub-dummy layer DL4-2f and the fourth sub-dummy layer DL4-4f may comprise the same material as each other. In one embodiment, the first sub-dummy layer DL4-1f and the third sub-dummy layer DL4-3f may comprise materials different from those of the second sub-dummy layer DL4-2f and the fourth sub-dummy layer DL4-4f. For example, the first sub-dummy layer DL4-1f and the third sub-dummy layer DL4-3f may comprise silicon oxynitride (SiON), and the second sub-dummy layer DL4-2f and the fourth sub-dummy layer DL4-4f may comprise silicon oxide (SiO2). xHowever, the substances included in the first sub-virtual layer DL4-1f, the second sub-virtual layer DL4-2f, the third sub-virtual layer DL4-3f, and the fourth sub-virtual layer DL4-4f according to embodiments of the present invention are not necessarily limited thereto.

[0162] As previously mentioned, in the window module WMf, the anti-reflective layer ARf can have a structure with alternating layers of low-refractive and high-refractive layers. Furthermore, the first thickness of the uppermost low-refractive layer, the first refractive layer L1, located in the anti-reflective layer ARf can be approximately 70 nm to approximately 120 nm. Additionally, the second thickness of the high-refractive layer L2, disposed below the first refractive layer L1, can be greater than the value of multiplying the first thickness of the first refractive layer L1 by 0.4 and less than the first thickness. Furthermore, the third thickness of the fifth refractive layer L5, the third low-refractive layer from the top of the anti-reflective layer ARf, can be approximately 50 nm or more. Furthermore, the fourth thickness of the eighth refractive layer L8, the lowermost high-refractive layer in the anti-reflective layer ARf, can be the largest among the high-refractive layers. Furthermore, the fifth thickness of the ninth refractive layer L9, the lowermost low-refractive layer in the anti-reflective layer ARf, can be approximately 20 nm or more. This reduces the area PA (see reference) in the planar region of the WMf form module. Figure 4 The light identified in the window module WMf and the curved surface region CA (refer to) Figure 4 This reduces the color difference between the lights identified in the form. Additionally, it can reduce the reflectivity of light reflected at the surface of the WMf window module.

[0163] Additionally, the window module WMf may also include a first dummy structure DS1 and a second dummy structure DS2f, which are disposed below the ninth refractive layer L9 and have a low-refractive layer and a high-refractive layer stacked on top of each other. Thus, Figure 13 The total thickness of the anti-reflective layer ARf can be greater than Figure 6 AR anti-reflective layer Figure 9 ARb anti-reflective layer and Figure 12 The thickness of each of the anti-reflective layers ARf is [determined]. Therefore, the durability of the window module WMf, which includes the anti-reflective layer ARf, can be further improved.

Figure 13 The form module WMf described differs from the reference form in its structure, except for the fourth virtual layer DL4g. Figure 13 The WMf form modules described herein have substantially the same or similar structures to each other. Below, descriptions may be omitted or briefly referenced. Figure 6 , Figure 12 as well as Figure 13 The description repeats the content of the form modules WM, WMe, and WMf.

[0166] Reference Figure 14 The anti-reflective layer ARg of the window module WMg may include a fourth dummy layer DL4g. The fourth dummy layer DL4g may have a multilayer structure with multiple low-refractive layers stacked on top of each other. For example, the fourth dummy layer DL4g may include a first sub-dummy layer DL4-1g, a second sub-dummy layer DL4-2g, and a third sub-dummy layer DL4-3g.

[0167] The first sub-dummy layer DL4-1g can be disposed below the third dummy layer DL3. In one embodiment, the first sub-dummy layer DL4-1g can be a low-refractive layer. For example, the first sub-dummy layer DL4-1g can include silicon oxide (SiO2). x ), silicon oxynitrides (SiON), etc.

[0168] The second sub-virtual layer DL4-2g can be disposed below the first sub-virtual layer DL4-1g. In one embodiment, the second sub-virtual layer DL4-2g can be a low-refractive layer. For example, the second sub-virtual layer DL4-2g can include silicon oxide (SiO2). x ), silicon oxynitrides (SiON), etc.

[0169] The third sub-dummy layer DL4-3g can be disposed below the second sub-dummy layer DL4-2g. In one embodiment, the third sub-dummy layer DL4-3g can be a low-refractive layer. For example, the third sub-dummy layer DL4-3g can include silicon oxide (SiO2). x ), silicon oxynitrides (SiON), etc.

[0170] In one embodiment, the first sub-virtual layer DL4-1g and the third sub-virtual layer DL4-3g may comprise the same material as each other. In another embodiment, the first sub-virtual layer DL4-1g and the third sub-virtual layer DL4-3g may comprise a material different from that of the second sub-virtual layer DL4-2g. For example, the first sub-virtual layer DL4-1g and the third sub-virtual layer DL4-3g may comprise silicon oxide (SiO2). x The second sub-dummy layer DL4-2g comprises silicon oxynitride (SiON). However, the substances included in the first sub-dummy layer DL4-1g, the second sub-dummy layer DL4-2g, and the third sub-dummy layer DL4-3g according to embodiments of the present invention are not necessarily limited thereto.

[0171] As previously mentioned, in the window module WMg, the antireflective layer ARg can have a structure with alternating layers of low-refractive and high-refractive layers. Furthermore, the first thickness of the uppermost low-refractive layer, the first refractive layer L1, located in the antireflective layer ARg can be approximately 70 nm to approximately 120 nm. Additionally, the second thickness of the high-refractive layer, the second refractive layer L2, disposed below the first refractive layer L1, can be greater than the value of multiplying the first thickness of the first refractive layer L1 by 0.4 and less than the first thickness. Furthermore, the third thickness of the fifth refractive layer L5, the third low-refractive layer from the uppermost point of the antireflective layer ARg, can be approximately 50 nm or more. Furthermore, the fourth thickness of the eighth refractive layer L8, the lowermost high-refractive layer in the antireflective layer ARg, can be the largest among the high-refractive layers. Furthermore, the fifth thickness of the ninth refractive layer L9, the lowermost low-refractive layer in the antireflective layer ARg, can be approximately 20 nm or more. This reduces the amount of time spent in the planar area PA of the window module WMg (see reference). Figure 4 The light identified in the window module WMg and the curved surface region CA (refer to) Figure 4 This reduces the color difference between the light sources identified in the model. Additionally, it can reduce the reflectivity of light reflected at the surface of the window module WMg.

[0172] Additionally, the window module WMg may also include a first dummy structure DS1 and a second dummy structure DS2g, disposed below the ninth refractive layer L9 and stacked with a low-refractive layer and a high-refractive layer. Thus, Figure 14 The total thickness of the anti-reflective layer ARg can be greater than Figure 6 Anti-reflective layer AR and Figure 9 The thickness of each of the anti-reflective layers ARb is thus increased. Therefore, the durability of the window module WMg, including the anti-reflective layer ARg, can be further improved.

[0173] In addition, with Figure 13 The fourth virtual layer DL4f includes four different layers. Figure 14 The fourth dummy layer DL4g can include three layers. Therefore, the thickness, reflectivity, and refractive index of the window module WMg, including the anti-reflective layer ARg, can be adjusted differently by forming low-refractive layers with various stacked structures.

Furthermore, the fourth thickness TH4 of the second highest high-refractive layer (the second from the bottom of the anti-reflective layer ARh), the eighth refractive layer L8, can be the largest among the high-refractive layers. Furthermore, the fifth layer TH5 of the low-refractive layer included in the anti-reflective layer ARh, specifically the ninth low-refractive layer L9 (the second lowest layer in the anti-reflective layer ARh), can be approximately 20 nm or more. This reduces the thickness of the planar region PA (see reference) of the window module WMh. Figure 4 The light identified in the window module WMh and the curved area CA (refer to) Figure 4 This reduces the color difference between the lights identified in the module. Additionally, it can reduce the reflectivity of light reflected at the surface of the window module WMh.

[0181] Additionally, a tenth refractive layer L10 and an eleventh refractive layer L11 can be disposed below the ninth refractive layer L9. Therefore, Figure 15 The total thickness of the anti-reflective layer ARh can be greater than Figure 6 The total thickness of the anti-reflective layer AR. Therefore, the durability of the window module WMh, which includes the anti-reflective layer ARh, can be further improved.

Thus, Figure 16 The total thickness of the anti-reflective layer ARi can be greater than Figure 15 The thickness of the anti-reflective layer ARh is increased. Therefore, the durability of the window module WMi, which includes the anti-reflective layer ARi, can be further improved.

[0225] [Table 9]

[0226] It can be confirmed that, referring to Table 1, compared to the thickness of the fifth refractive layer of the antireflective layer according to the [Comparative Example] which is less than 50 nm, referring to Tables 2 to 6, the thickness of the fifth refractive layer of the antireflective layer of each of the window modules according to [Example 1 to Example 12] is more than 50 nm.

[0227] It can be confirmed that, referring to Tables 8 and 9, the reflectivity of each window module according to [Examples 1 to 12] is less than that of the window module according to [Comparative Example]. It can be confirmed that the reflectivity of each window module according to [Examples 1 to 12] is 0.75 or less, but the reflectivity of the window module according to [Comparative Example] is 0.93. Furthermore, it can be confirmed that the reflectivity of the window module according to [Comparative Example] near a wavelength of 480nm has a value close to 0.02, but the reflectivity of each window module according to [Examples 1 to 12] has a relatively uniform reflectivity near a wavelength of 0.01. Therefore, it can be confirmed that the reflectivity of the window module according to the embodiments of the present invention is relatively low.

[0228] Furthermore, it can be confirmed that the sum of the thicknesses of the anti-reflective layers according to [Examples 1 to 12] is greater than the sum of the thicknesses of the anti-reflective layers according to [Comparative Example]. Therefore, it can be confirmed that the total thickness of the window module including the anti-reflective layers according to embodiments of the present invention is increased, thus improving durability.

[0229] Furthermore, it can be confirmed that the color difference of each of the window modules according to [Examples 1 to 8] is 4.0 or less. Additionally, it can be confirmed that the color difference of each of the window modules according to [Examples 1 to 12] can also be made to achieve a relatively low color difference based on θ.
