[0070] The reflection prevention layer RPL is arranged on the input sensing part ISP. The reflection prevention layer RPL can be manufactured directly on the input sensing part ISP during the manufacture of the display device DD. However, the embodiments of the present disclosure are not necessarily limited thereto, and in some embodiments, the reflection prevention layer RPL can be manufactured as a separate panel and attached to the input sensing part ISP through an adhesive layer.
[0071] The anti-reflection layer RPL is a film that prevents reflection of external light. The anti-reflection layer RPL reduces reflection of external light incident from above the display device DD toward the display panel DP. Due to the anti-reflection layer RPL, the external light may not be visible to the user.

[0078] The window WD includes a first flat portion WP1 and first curved portions WC1 extending from both sides of the first flat portion WP1 opposite to each other in the first direction DR1. The window WD has a top surface including curved surfaces, each of which convexly projects upward when viewed in the second direction DR2.
[0079] The first flat portion WP1 and Figure 6 The first curved portion WC1 corresponds to the flat surface area DD-P shown in FIG. Figure 6 The curved surface area DD-C shown in FIG.
[0080] The window WD includes optically transparent glass. However, the embodiments of the present disclosure are not necessarily limited thereto, and in some embodiments, the window WD includes a synthetic resin film.
[0081] The anti-glare layer AGL is arranged on the window WD. The anti-glare layer AGL is arranged on the top surface of the window WD. Figure 1 The window deposition device WSM shown in FIG. 4 forms an anti-glare layer AGL on a window WD.
[0082] The anti-glare layer AGL includes a second flat portion WP2 and second curved portions WC2 extending from both sides of the second flat portion WP2 opposite to each other in the first direction DR1. The anti-glare layer AGL has a top surface including curved surfaces, each of which convexly projects upward when viewed in the second direction DR2.
[0083] The second flat portion WP2 is arranged on the first flat portion WP1. The second flat portion WP2 overlaps the first flat portion WP1. Figure 6 It corresponds to the flat surface area DD-P shown in FIG.
[0084] Each of the plurality of second curved portions WC2 is arranged on a corresponding first curved portion WC1. The plurality of second curved portions WC2 overlap the plurality of first curved portions WC1, respectively. Each of the plurality of first curved portions WC1 has a top surface having the same curvature as the bottom surface of each of the plurality of second curved portions WC2. Figure 6 The curved surface area DD-C shown in FIG.
[0085] In addition, the anti-glare layer AGL has a surface including protrusions. The protrusions of the anti-glare layer AGL diffusely reflect external incident light toward the display panel DP. Therefore, the reflected external light is prevented from being incident on the eyes of the user, thereby preventing glare.
[0086] The anti-reflection layer ARL is disposed on the anti-glare layer AGL. The anti-reflection layer ARL is disposed on the top surface of the anti-glare layer AGL. Figure 1 The window deposition apparatus WSM shown in FIG. 4 forms an anti-reflection layer ARL on the anti-glare layer AGL.

Each of the plurality of third curved portions WC3 overlaps each of the plurality of first curved portions WC1 and each of the plurality of second curved portions WC2, respectively. Each of the plurality of second curved portions WC2 has a top surface having the same curvature as the bottom surface of each of the plurality of third curved portions WC3. Figure 6 The curved surface area DD-C shown in FIG.
[0090] The anti-reflection layer ARL includes silicon dioxide (SiO 2 ) and titanium dioxide (TiO 2 ) at least one of. However, the embodiments of the present disclosure are not necessarily limited thereto, and in an embodiment, the anti-reflection layer ARL includes magnesium fluoride (MgF 2 ).
[0091] Light incident from the outside toward the display panel DP is not reflected by the anti-reflection layer ARL. For example, the phase of the light reflected from the window WD and the phase of the light reflected from the anti-reflection layer ARL are different from each other. The light reflected from the window WD and the light reflected from the anti-reflection layer ARL destructively interfere with each other. Therefore, the anti-reflection layer ARL reduces the reflection of the window module WM and prevents the reflected external light from being visible to the user.
[0092] The anti-fingerprint layer AFL is disposed on the anti-reflection layer ARL. The anti-fingerprint layer AFL is disposed on the top surface of the anti-reflection layer ARL.

Each of the plurality of third curved portions WC3 has a top surface having the same curvature as the bottom surface of each of the plurality of fourth curved portions WC4. Figure 6 The curved surface area DD-C shown in FIG.
[0096] The anti-fingerprint layer AFL includes a waterproof coating. For example, the anti-fingerprint layer AFL includes a fluorine coating. Therefore, the anti-fingerprint layer AFL is waterproof and oil-proof, and prevents the user's fingerprints from remaining on the surface of the window module WM and prevents contaminants from being attached to the window module WM.
[0097] Figure 8 The anti-glare layer AGL, the anti-reflection layer ARL, and the anti-fingerprint layer AFL are illustrated as being arranged on the window WD, but the embodiments of the present disclosure are not necessarily limited thereto. For example, any one layer may be omitted. For another example, in addition to the anti-glare layer AGL, the anti-reflection layer ARL, and the anti-fingerprint layer AFL, another layer may be additionally deposited on the window WD.
[0098] 9A to 9C Pictured Figure 8 Deposition of window modules.
[0099] For example, Fig. 9A It is a floor plan. Fig. 9B is along Figure 3 A cross-sectional view taken along line II-II' in FIG. Fig. 9C The window deposition apparatus WSM is illustrated when viewed in a first direction DR1 .

The window WD is arranged in the opening portion WOP while being turned upside down. The front surface of the window WD is oriented downward. The window WD is arranged so that the rear surface of the window WD is positioned at a higher level than the front surface of the window WD.
[0103] The opening portion WOP exposes a portion of the window WD from the seating portion JG. For example, the window WD contacts the inner surface ISD of the seating portion JG that defines the opening portion WOP. Each of the plurality of first curved portions WC1 has a portion arranged on the seating surface ANP. Therefore, the window WD is in close contact with the seating portion JG. In the window WD, a portion of each of the plurality of first curved portions WC1 and the first flat portion WP1 are exposed by the seating portion JG.
[0104] refer to Figure 8 , Fig. 9B and Fig. 9C In an embodiment, the window WD is arranged on the seating portion JG, and then the seating portion JG is arranged in the chamber CH. The seating portion JG is connected to the driving portion DC. The driving portion DC rotates the seating portion JG around a rotation axis parallel to the third direction DR3.
[0105] When the seating part JG is arranged in the chamber CH, the heat source HS of the ejection part SP heats the deposition material in the crucible CRB. For example, the heat source HS heats the crucible CRB by one of an electron beam evaporation method that converts kinetic energy of electrons into thermal energy and a sputtering method that converts electrical energy of plasma into kinetic energy.
[0106] The deposition material in the crucible CRB is heated by the heat source HS and evaporated. The deposition material can be used to form an anti-glare layer AGL, an anti-reflection layer ARL, and an anti-fingerprint layer AFL. When the deposition material has evaporated into a gaseous state, the wing SW arranged on the ejection portion SP rotates. The deposition material is uniformly deposited on the placement portion JG through the wing SW.
[0107] The deposition material is deposited on the window WD arranged in the opening portion WOP. The deposition material is deposited on a portion of the window WD exposed by the seating portion JG. The deposition material moves toward the window WD along the induction surface INP. The deposition material is deposited on the front surface of the window WD.
[0108] Different deposition materials can be deposited multiple times on the front surface of the window WD to produce Figure 8 The window module WM in.
[0109] refer to Fig. 9B and Fig. 9C In an embodiment, when the window WD is not seated on the seating portion JG, the vapor deposition material is deposited on each of the front and rear surfaces of the window WD. For example, stains are generated on the rear surface of the window WD. The stains generated on the rear surface cause appearance defects of the window WD. In addition, the stains reduce the adhesion between the window WD and the second adhesive layer AL2 (see Figure 7 ) between them, resulting in the display device DD (see Figure 6 ) defects.
[0110] However, when the window deposition apparatus WSM according to an embodiment of the present disclosure is used to deposit a deposition material on the window WD, the window WD is in close contact with the inner surface ISD of the seating portion JG. Therefore, the gaseous deposition material is deposited on the front surface of the window WD, but not on the rear surface of the window WD. Therefore, no stain is generated, which prevents appearance defects of the window WD. In addition, the window WD is prevented from being in contact with the second adhesive layer AL2 (see Figure 7 ) between the display device DD (see Figure 6 ) defects.

[0112] Table 1
[0113]
[0114] Table 2
[0115] For example, Table 1 shows the window module WM according to the comparative example (see Figure 7 ), and Table 2 shows the experimental data of the window module WM manufactured by the window deposition apparatus according to the embodiment of the present disclosure (see Figure 7 )’s experimental data.
[0116] refer to Figure 7As with Table 1 and Table 2, an experiment on the adhesion between the window module WM and the second adhesive layer AL2 is implemented through a contact angle experiment. The contact angle experiment is to measure the contact angle between the rear surface of the window module WM and the droplet when the droplet falls on the rear surface of the window module WM. The contact angle is defined as the angle obtained by measuring the angle between the liquid surface and the rear surface of the window module WM from the inside of the liquid. As the hydrophilicity of the rear surface of the window module WM decreases, the contact angle may increase. For example, as the contact angle increases, the adhesion between the rear surface of the window module WM and the second adhesive layer AL2 decreases.
[0117] refer to Figure 8 and Table 1, in an embodiment, when the deposition material is deposited on the rear surface of the window module WM, the average contact angle is about 63.05 degrees, as shown in Table 1. The results show that the hydrophilicity of the rear surface of the window module WM is reduced. Therefore, the adhesion between the window module WM and the second adhesive layer AL2 is reduced.
[0118] refer to Figure 8 , Fig. 9B and Table 2, in an embodiment, when the window deposition apparatus according to an embodiment of the present disclosure is used to manufacture the window module WM, the window WD is in close contact with the inner surface ISD of the seating portion JG. Therefore, the deposition material is not deposited on the rear surface of the window WD. As shown in Table 2, the average contact angle is about 53.98 degrees. The results show that the hydrophilicity of the rear surface of the window module WM is not reduced. Therefore, the adhesive force between the window module WM and the second adhesive layer AL2 is not reduced, which prevents the display device DD (see Figure 6 ) defects.
[0119] According to an embodiment of the present disclosure, the inner surface of the placement portion defining the opening portion includes: a first inner surface; a second inner surface, which is arranged on the first inner surface; a placement surface, which connects the upper end of the first inner surface and the lower end of the second inner surface to each other; an induction surface, which connects the first inner surface and the bottom surface of the placement portion to each other; and a guide surface, which connects the second inner surface and the top surface of the placement portion to each other. The window is arranged in the opening portion. The window is in close contact with the inner surface of the placement portion. Therefore, the deposition material is deposited on the front surface of the window and not on the rear surface of the window.
