Like reference numerals or symbols refer to like elements throughout.

[0024] When an element or layer is referred to as being “on” another element or layer, it includes not only the case where the element or layer is directly on the other element or layer, but also the case where intervening elements or layers are disposed between the element or layer and the other element or layer. In contrast, when an element is referred to as being “directly on” another element or layer, it means that no intervening elements or layers are disposed therebetween. As used herein, the term “and / or” includes any and all combinations of one or more of the referenced items.

[0025] Spatially relative terms such as "below," "beneath," "below," "above," and "upper" may be used herein to readily describe the relationship of one element or feature to another element or feature as illustrated in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of an element in use or operation in addition to the orientation depicted in the drawings. Like reference numerals or symbols refer to like elements throughout.

[0026] Although the terms "first," "second," etc., may be used herein to describe various elements, components, and / or parts, these elements, components, and / or parts are not limited by these terms. These terms are used to distinguish one element, component, or part from another element, component, or part. Therefore, without departing from the spirit of the present invention, the first element, component, or part mentioned below may be a second element, component, or part.

[0027] The embodiments described herein will be described with reference to plan views and cross-sectional views which are idealized schematic views of the present invention. Therefore, the shapes of the illustrative drawings may change due to manufacturing techniques and / or tolerances. Therefore, the embodiments of the present invention are not limited to the specific forms shown herein and include changes in form that may occur depending on the manufacturing process. Therefore, the regions shown in the drawings as examples are of a schematic nature, and the shapes of the regions shown in the drawings are intended to provide examples of specific forms of regions of elements and are not intended to limit the scope of the present invention.

[0028] 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 measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, a term such as "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0029] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. It will also be understood that, unless expressly defined as such herein, terms such as those defined in general 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.

[0030] Hereinafter, embodiments of the present inventive concept will be described in detail with reference to the accompanying drawings.

[0031] Figure 1 is a perspective view of an embodiment of an electronic device according to the present invention. Figure 2 Show Figure 1 The electronic device in the device is folded.

[0032] Reference Figure 1 In an embodiment of the present invention, the electronic device ED may have a quadrilateral shape, for example, a rectangular shape having long sides extending in a first direction DR1 and short sides extending in a second direction DR2 intersecting the first direction DR1. However, the present invention is not limited thereto, and the electronic device ED may have various shapes, such as a circle and other polygons. The electronic device ED may be a flexible electronic device.

[0033] 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. Furthermore, as used herein, the term "in a plan view" may be defined as a state viewed in the third direction DR3. Furthermore, as used herein, the term "overlap" may refer to a state in which components are arranged to overlap each other in a plan view.

[0034] The electronic device ED may include a folding area FA and a plurality of non-folding areas NFA1 and NFA2. The non-folding areas NFA1 and NFA2 may include a first non-folding area NFA1 and a second non-folding area NFA2. The folding area FA may be disposed between the first non-folding area NFA1 and the second non-folding area NFA2. The first non-folding area NFA1, the folding area FA, and the second non-folding area NFA2 may be arranged in a first direction DR1.

[0035] In the embodiment, one folding area FA and two non-folding areas NFA1 and NFA2 are shown, but the number of folding areas FA and the number of non-folding areas NFA1 and NFA2 are not limited thereto. In the embodiment, for example, the electronic device ED may include more than two non-folding areas and multiple folding areas arranged between the non-folding areas.

[0036] An upper surface of the electronic device ED may be defined as a display surface DS and may have a plane defined by a first direction DR1 and a second direction DR2. An image IM generated from the electronic device ED may be provided to a user through the display surface DS.

[0037] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA. The display area DA may display an image, while the non-display area NDA may not display an image. The non-display area NDA may surround the display area DA and define an edge of the electronic device ED printed in a predetermined color.

[0038] Although not shown, the electronic device ED may include a plurality of sensors and at least one camera.

[0039] Reference Figure 2 The electronic device ED may be a foldable electronic device ED that can be folded or unfolded. In an embodiment, for example, the folding area FA may be bent about a folding axis FX parallel to the second direction DR2, thereby allowing the electronic device ED to be folded. The electronic device ED may have a curvature radius R while being folded. The folding axis FX may be defined as a short axis parallel to a short side of the electronic device ED.

[0040] When the electronic device ED is folded, the electronic device ED may be folded inward so that the first non-folding area NFA1 and the second non-folding area NFA2 face each other, and the display surface DS (refer to FIG. Figure 1 ) is not exposed to the outside. However, the present invention is not limited thereto. In an embodiment, for example, the electronic device ED may be folded outwardly relative to the folding axis FX so that the display surface DS is exposed to the outside.

[0041] Figure 3It is an exploded perspective view of an embodiment of an electronic device according to the concept of the present invention. Figure 4 It is along Figure 3 A cross-sectional view taken along line II' in FIG.

[0042] Reference Figure 3 and Figure 4 , the electronic device ED may include a display device DD and a housing HU. Although not shown, the electronic device ED may further include a mechanical structure for controlling a folding operation of the display device DD.

[0043] The display device DD in an embodiment of the present invention may include a display module DM for displaying an image, an upper module UM disposed on the display module DM, and a lower module LM disposed below the display module DM. The display module DM may constitute a portion of the display device DD, and specifically, the display module DM may generate an image. The display module DM may display an image in response to an electrical signal and transmit / receive information regarding an external input. An active area AA and a peripheral area NAA may be defined within the display module DM. The active area AA may be defined as an area from which an image provided by the display module DM is emitted.

[0044] The peripheral area NAA is adjacent to the active area AA. In an embodiment, for example, the peripheral area NAA may surround the active area AA. However, this is an illustrative embodiment, and the peripheral area NAA may be defined in various shapes and is not limited to a specific embodiment. In an embodiment, the active area AA of the display module DM may be adjacent to the active area AA. Figure 1 Overlapping at least a portion of the display area DA in .

[0045] The display module DM may include a display panel DP and an input sensing unit ISP. The display panel DP in the embodiments of the present invention may be a light-emitting display panel, but the embodiments of the present invention are not particularly limited thereto. In embodiments, for example, the display panel DP may be an organic light-emitting display panel, an inorganic light-emitting display panel, or a quantum dot light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include an organic light-emitting material, and the light-emitting layer of the inorganic light-emitting display panel may include an inorganic light-emitting material. The light-emitting layer of the quantum dot light-emitting display panel may include quantum dots, quantum rods, etc. Hereinafter, the display panel DP will be described as an organic light-emitting display panel.

[0046] The display panel DP may be a flexible display panel. Therefore, the display panel DP may be completely rolled or folded or unfolded with respect to the folding axis FX.

[0047] The input sensing unit ISP may be disposed directly on the display panel DP. In an embodiment of the present invention, the input sensing unit ISP may be formed on the display panel DP through a continuous process. That is, when the input sensing unit ISP is disposed directly on the display panel DP, no adhesive film is disposed between the input sensing unit ISP and the display panel DP. However, the present invention is not limited thereto. An adhesive film may be disposed between the input sensing unit ISP and the display panel DP. In this case, the input sensing unit ISP and the display panel DP may not be manufactured through a continuous process, and the input sensing unit ISP may be manufactured through a process separate from the process for the display panel DP and then fixed to the upper surface of the display panel DP using an adhesive film.

[0048] The display panel DP generates an image, and the input sensing unit ISP acquires coordinate information about a user's input (eg, a touch event).

[0049] The upper module UM may include a window WM provided on the display module DM. The window WM may include an optically transparent insulating material. Therefore, an image generated from the display module DM may be easily perceived by a user through the window WM. Figure 7 Let's describe window WM in detail.

[0050] The upper module UM may further include at least one functional layer disposed between the display module DM and the window WM. In an embodiment of the present inventive concept, the functional layer may be an anti-reflection layer RPL for preventing external light from being reflected.

[0051] The anti-reflection layer RPL can prevent the components constituting the display module DM from being visible from the outside due to external light incident through the front surface of the display device DD. The anti-reflection layer RPL may include a retarder and a polarizer. The retarder may be a film-type retarder or a liquid crystal coating-type retarder, and may include a λ / 2 retarder and / or a λ / 4 retarder. However, the present disclosure is not limited thereto, and the retarder may include various other wave phase retarders. The polarizer may also be a film-type polarizer or a liquid crystal coating-type polarizer. The film-type may include a stretched synthetic resin film, and the liquid crystal coating-type may include liquid crystals arranged in a predetermined arrangement. The retarder and the polarizer may be implemented as a single polarizing film. The functional layer may also include a protective film disposed above or below the anti-reflection layer RPL.

[0052] The lower module LM may include a support plate SP disposed on the rear surface of the display module DM to support the display module DM, and a protective film PF disposed between the display module DM and the support plate SP. The support plate SP may include a number of support plates corresponding to the number of the non-folding areas NFA1 and NFA2. In an embodiment of the present invention, the support plate SP may include a first support plate SP1 and a second support plate SP2 spaced apart from the first support plate SP1.

[0053] The first support plate SP1 and the second support plate SP2 may be disposed to correspond to the first non-folding area NFA1 and the second non-folding area NFA2, respectively. The first support plate SP1 is disposed to overlap with the first non-folding area NFA1 of the display module DM, and the second support plate SP2 is disposed to overlap with the second non-folding area NFA2 of the display module DM. Each of the first support plate SP1 and the second support plate SP2 may comprise a metal material or a plastic material.

[0054] When the display module DM is Figure 1 When the display module DM is in the expanded state shown in FIG, the first support plate SP1 and the second support plate SP2 are spaced apart from each other in the first direction DR1. Figure 2 When folded about the folding axis FX as shown in FIG, the first support plate SP1 and the second support plate SP2 may be spaced apart from each other in the third direction DR3.

[0055] The first support plate SP1 and the second support plate SP2 may be spaced apart from each other relative to the folding area FA. The first support plate SP1 and the second support plate SP2 may overlap a portion of the folding area FA. That is, the spacing distance between the first support plate SP1 and the second support plate SP2 in the first direction DR1 may be less than the width of the folding area FA.

[0056] Although not shown, the support plate SP may further include a connection module for connecting the first support plate SP1 and the second support plate SP2. The connection module may include a hinge module or a multi-joint module.

[0057] The support plate SP is shown as including two support plates SP1 and SP2, but the present invention is not limited thereto. That is, when multiple folding axes FX are provided, the support plate SP can include multiple support plates spaced apart from each other relative to the multiple folding axes FX. Furthermore, the support plate SP can be provided as a single piece, rather than being separated into the first support plate SP1 and the second support plate SP2. In this case, a bent portion can be provided in the support plate SP to correspond to the folding area FA. An opening defined through the support plate SP or a groove recessed from one surface of the support plate SP can be provided in the bent portion.

[0058] A protective film PF may be provided between the display module DM and the support plate SP. The protective film PF may be provided below the display module DM to protect the rear surface of the display module DM. For example, the protective film PF may include a synthetic resin film, such as a polyimide film or a polyethylene terephthalate film. However, this is an illustrative embodiment, and the protective film PF is not limited thereto.

[0059] The housing HU can be coupled to the display device DD, specifically, to the window WM, and accommodate the display module DM and the lower module LM. The housing HU is shown as including a first housing HU1 and a second housing HU2 that are separated from each other, but the present invention is not limited thereto. Although not shown, the electronic device ED may further include a hinge structure for connecting the first housing HU1 and the second housing HU2.

[0072] The scan driver SDV and the emission driver EDV may be disposed in the peripheral area NAA. The scan driver SDV and the emission driver EDV may be disposed in portions of the peripheral area NAA adjacent to opposite sides of the first area AA1 in the second direction DR2. The data driver DDV may be disposed in the second area AA2. The data driver DDV may be manufactured in the form of an integrated circuit chip and disposed (e.g., mounted) on the second area AA2.

[0093] Multiple patterns GR may be defined in the patterned portion PGA. The patterns GR may include a first pattern GRU and a second pattern GRB. The first pattern GRU may be defined in the upper surface PG-F of the patterned glass PG. Herein, expressions such as "...the pattern / groove is defined in the upper surface of A" mean that the pattern / groove extends downward from the upper surface of A into A. Expressions such as "...the pattern / groove is defined in the lower surface of A" mean that the pattern / groove extends upward from the lower surface of A into A. In a plan view, the first patterns GRU may extend in the second direction DR2 and may be arranged spaced apart from each other in the first direction DR1. The first patterns GRU may extend in a third direction DR3 from the upper surface PG-F toward the lower surface PG-B of the patterned glass PG.

[0098] The second groove GR2 may be defined below the first groove GR1. The second groove GR2 may extend from the first groove GR1 toward the lower surface PG-B of the patterned glass PG in the third direction DR3. The width of each of the plurality of second grooves GR2 in the first direction DR1 may decrease toward the lower surface PG-B of the patterned portion PGA. In an embodiment, for example, the third width W3 of the upper end of each of the plurality of second grooves GR2 adjacent to the first groove GR1 may be greater than the fourth width W4 of the lower end of each of the plurality of second grooves GR2 adjacent to the lower surface PG-B of the patterned glass PG.

[0099] The width of each of the plurality of second grooves GR2 in the first direction DR1 may be greater than the width of each of the plurality of first grooves GR1 in the first direction DR1.

[0100] Since the width of each of the plurality of second grooves GR2 in the first direction DR1 may be greater than the width of each of the plurality of first grooves GR1 in the first direction DR1 , the inner surface of the patterning portion PGA defining the first and second grooves GR1 and GR2 may have a step.

The seventh width W7 at the lower end and the eighth width W8 at the upper end of each of the plurality of fourth grooves GR4 may be greater than the sixth width W6 of each of the plurality of third grooves GR3.

[0111] Since the width of each of the plurality of fourth grooves GR4 in the first direction DR1 may be greater than the width of each of the plurality of third grooves GR3 in the first direction DR1 , the inner surface of the patterning portion PGA defining the third and fourth grooves GR3 and GR4 may have a step.

[0113] However, this is an illustrative embodiment, and thus the first pattern GRU and the second pattern GRB may have different shapes. Figure 11 Provide a detailed description.

[0114] When viewed in the second direction DR2, the first groove GR1 and the third groove GR3 may be alternately and oppositely disposed.When viewed in the second direction DR2, the second groove GR2 and the fourth groove GR4 may be alternately and oppositely disposed.

[0116] The first filling resin FL1 may have a shape corresponding to the shapes of the first and second grooves GR1 and GR2 . The second filling resin FL2 may have a shape corresponding to the shapes of the third and fourth grooves GR3 and GR4 .

[0117] Therefore, the width of each of the plurality of first filling resins FL1 adjacent to the upper surface PG-F of the patterned glass PG may be the same as the second width W2. The width of each of the plurality of second filling resins FL2 adjacent to the lower surface PG-B of the patterned glass PG may be the same as the sixth width W6.

[0118] A first width W1 of each of the plurality of first surfaces PL1 in the first direction DR1 may be greater than a second width W2 of each of the plurality of first filling resins FL1. A fifth width W5 of each of the plurality of second surfaces PL2 may be greater than a sixth width W6 of each of the plurality of second filling resins FL2.

[0119] Reference Figure 10 In a comparative example, a first groove GR1' of a first pattern GRU' of a plurality of patterns GR' may be defined in the upper surface PG-F' of the patterned glass PG'. The first grooves GR1' may be defined to be spaced apart from each other in the first direction DR1. The upper surface of the patterned glass PG' disposed between adjacent first grooves GR1' in the first direction DR1 may be defined as a first surface PL1'. The width of the first surface PL1' in the first direction DR1 may be defined as a (1-1)th width W1-1. When viewed in the second direction DR2, the width of each of the first grooves GR1' in the first direction DR1 may be defined as a (2-1)th width W2-1.

[0120] The first groove GR1' may extend from the upper surface PG-F' of the patterned glass PG' toward the lower surface PG-B' of the patterned glass PG' in the third direction DR3. A first filling resin FL1' may be disposed in the first groove GR1'. The first filling resin FL1' may have a shape corresponding to the shape of the first groove GR1'. Therefore, the width of each of the plurality of first filling resins FL1' adjacent to the upper surface PG-F' of the patterned glass PG' may be the same as the (2-1)th width W2-1.

[0121] The second grooves GR2' of the second pattern GRB' among the plurality of patterns GR' may be defined in the lower surface PG-B' of the patterned glass PG'. The second grooves GR2' may be defined to be spaced apart from each other in the first direction DR1. The lower surface PG-B' of the patterned glass PG' disposed between adjacent second grooves GR2' in the first direction DR1 may be defined as a second surface PL2'. The width of the second surface PL2' in the first direction DR1 may be defined as a (5-1)th width W5-1. When viewed in the second direction DR2, the width of each of the plurality of second grooves GR2' in the first direction DR1 may be defined as a (6-1)th width W6-1.

[0122] The second groove GR2' may extend from the lower surface PG-B' of the patterned glass PG' toward the upper surface PG-F' of the patterned glass PG' in the third direction DR3. A second filling resin FL2' may be disposed in the second groove GR2'. The second filling resin FL2' may have a shape corresponding to the shape of the second groove GR2'. Therefore, the width of each of the plurality of second filling resins FL2' adjacent to the lower surface PG-B' of the patterned glass PG' may be the same as the (6-1)th width W6-1.

[0123] Reference Figure 9 and Figure 10 The upper surfaces PG-F and PG-F' of the patterned glasses PG and PG' can each be a display device DD (refer to Figure 3 Since the areas of the first filling resins FL1 and FL1′ exposed to the outside from the upper surfaces PG-F and PG-F′ increase in the areas of the upper surfaces PG-F and PG-F′ of the patterned glasses PG and PG′, the first grooves GR1 and GR1′ may be visible to the user.

[0124] In an embodiment, the ratio of the (2-1)th width W2-1 to the (1-1)th width W1-1 may be greater than the ratio of the second width W2 to the first width W1. In other words, the value of the (2-1)th width W2-1 divided by the (1-1)th width W1-1 may be greater than the value of the second width W2 divided by the first width W1. The (2-1)th width W2-1 may be greater than the second width W2.

[0125] The ratio of the (6-1)th width W6-1 to the (5-1)th width W5-1 may be greater than the ratio of the sixth width W6 to the fifth width W5. That is, the value of the (6-1)th width W6-1 divided by the (5-1)th width W5-1 may be greater than the value of the sixth width W6 divided by the fifth width W5. The (6-1)th width W6-1 may be greater than the sixth width W6.

[0126] Accordingly, Figure 9 The second width W2 of each of the plurality of first grooves GR1 may be less than Figure 10 The width W2-1 of each of the plurality of first grooves GR1' is (2-1), and Figure 9 The sixth width W6 of each of the plurality of third grooves GR3 may be less than Figure 10 The (6-1)th width W6-1 of each of the second grooves GR2' in the embodiment. Figure 9 The first pattern GRU and the second pattern GRB on the patterned glass PG in FIG may be less likely to be visible to the user.

[0127] Reference Figure 10, light can be transmitted from the display panel DP (refer to Figure 3 ) toward the display surface DS (refer to Figure 1 ) emission. Light can pass through the patterned glass PG'. The refractive index of the patterned glass PG' and the refractive index of the second filling resin FL2' can be different. Therefore, the path of light incident on the second surface PL2' and the path of light incident on the second filling resin FL2' can be different. Therefore, the second filling resin FL2' may be visible to the user.

[0128] Reference Figure 9 and Figure 10 , the sixth width W6 of each of the plurality of second filling resins FL2 may be smaller than the (6-1)th width W6-1. The ratio of the sixth width W6 to the fifth width W5 may be smaller than the ratio of the (6-1)th width W6-1 to the (5-1)th width W5-1. That is, the value of the sixth width W6 divided by the fifth width W5 may be smaller than the value of the (6-1)th width W6-1 divided by the (5-1)th width W5-1. Therefore, even when the path of light incident on the second surface PL2 and the path of light incident on the second filling resin FL2 are different from each other, the second filling resin FL1 may not be visible to the user.

[0137] Figure 11 is a diagram for describing another embodiment of patterned glass.

[0138] In an embodiment, Figure 11 It is along Figure 8 A cross-sectional view taken along line II-II'.

[0139] because Figure 11 The first pattern GRU and the first filling resin FL1 are Figure 9 The first pattern GRU and the first filling resin FL1 are the same, so their description will be omitted or briefly made.

[0140] Reference Figure 11 , the fifth groove GR5 of the second pattern GRB" among the plurality of patterns GR" may be defined in the lower surface PG-B of the patterned glass PGa.

[0145] In the embodiment, the fifth groove GR5 is defined in the lower surface PG-B of the patterned glass PGa, but the present invention is not limited thereto. Figure 1 ), the fifth groove GR5 may be defined in the upper surface PG-F of the patterned glass PGa, and the first groove GR1 and the second groove GR2 may be defined in the lower surface PG-B of the patterned glass PGa.

[0146] 12A to 12E Is used to describe manufacturing Figure 7 The window method is shown in Figure 4. Figure 13A and Figure 13B A comparative example of patterned glass is shown.

[0147] In an embodiment, 12A to 13A is a perspective view, and Figure 13B It is a cross-sectional view.

[0148] because 12A to 12E The first pattern GRU, the second pattern GRB, the protective layer PLL and the first window adhesive layer W_AL1 and the second window adhesive layer W_AL2 in the embodiment of the present invention are connected with the first pattern GRU, the second pattern GRB, the protective layer PLL and the first window adhesive layer W_AL1 and the second window adhesive layer W_AL2 in the embodiment of the present invention. Figures 7 to 9 The first pattern GRU, the second pattern GRB, the protection layer PLL, and the first and second window adhesive layers W_AL1 and W_AL2 are the same, so descriptions thereof will be omitted or briefly made.

[0149] Reference Figure 12A , a method for manufacturing a window may include forming a first pattern GRU and a second pattern GRB. A light irradiation unit RSE may be disposed above the glass BG. The light irradiation unit RSE may emit strong light (e.g., a laser beam RSB) onto the glass BG. One surface of the glass BG may be irradiated with a laser beam (e.g., an ultrashort pulse laser beam) RSB. The first pattern GRU and the second pattern GRB may be defined in the glass BG by the laser beam RSB. Each of the first pattern GRU and the second pattern GRB may extend in the second direction DR2 and may be arranged in the first direction DR1. The first pattern GRU and the second pattern GRB may extend in the second direction DR2 and may be defined on two sides of the patterned glass PG that are opposite to each other in the second direction DR2.

[0150] Reference Figure 12B After defining the first pattern GRU and the second pattern GRB, the first pattern GRU and the second pattern GRB may be sealed. The first window adhesive layer W_AL1 may be provided on the lower surface PG-B of the patterned glass PG. The first window adhesive layer W_AL1 may cover the second pattern GRB defined on the lower surface PG-B of the patterned glass PG.

[0151] The first protection layer PLL1 may be disposed on a lower surface of the first window adhesive layer W_AL1. The first window adhesive layer W_AL1 may be disposed between the first protection layer PLL1 and the patterned glass PG. The first protection layer PLL1 and the patterned glass PG may be bonded to each other through the first window adhesive layer W_AL1.

[0152] The second window adhesive layer W_AL2 may be disposed on the upper surface PG-F of the patterned glass PG. The second window adhesive layer W_AL2 may cover the first pattern GRU defined on the upper surface PG-F of the patterned glass PG.

[0153] The second protection layer PLL2 may be disposed on an upper surface of the second window adhesive layer W_AL2. The second window adhesive layer W_AL2 may be disposed between the second protection layer PLL2 and the patterned glass PG. The second protection layer PLL2 and the patterned glass PG may be bonded to each other through the second window adhesive layer W_AL2.

[0154] The first pattern GRU adjacent to the upper surface PG-F of the patterned glass PG and the second pattern GRB adjacent to the lower surface PG-B of the patterned glass PG may be sealed with the second window adhesive layer W_AL2 and the first window adhesive layer W_AL1 .

[0155] Reference Figure 12C and Figure 12E , after sealing the first and second patterns GRU and GRB, filling the first and second patterns GRU and GRB with resin may be performed.

[0156] Filling the first and second patterns GRU and GRB with the resin RS may include preparing a water tank BK. A receiving groove SOP may be defined in an upper surface of the water tank BK. The receiving groove SOP may extend from the upper surface to the lower surface of the water tank BK.

[0157] After the water tank BK is prepared, the resin RS may be supplied to the receiving groove SOP. The tube TBE may then be connected to the patterned glass PG. The tube TBE may have one side and an opposite side facing each other in the third direction DR3. The one side is connected to the patterned glass PG, and the opposite side is disposed on the resin RS.

[0158] The resin RS can move toward the first and second patterns GRU and GRB by capillary action. Specifically, the adhesive strength between the resin RS and the inner surface of the tube TBE can be greater than the cohesive strength between the molecules of the resin RS. Therefore, the resin RS can rise along the inner surface of the tube TBE.

[0159] After being supplied to the patterned glass PG through the tube TBE, the resin RS can be filled into the first and second patterns GRU and GRB. The adhesive force between the resin RS and the patterned glass PG can be greater than the cohesive force between the molecules of the resin RS. Therefore, the resin RS can rise along the inner surface of the patterned glass PG that defines the first and second patterns GRU and GRB.

[0160] Although not shown, after the first and second patterns GRU and GRB are filled with the resin RS, the resin RS may be cured. In an embodiment, the resin RS may be cured by thermal curing or ultraviolet curing. When the resin RS is cured, the first filling resin FL1 (refer to FIG. Figure 7 ) and the second filling resin FL2 (refer to Figure 7) can be obtained.

[0161] Reference Figure 13A and Figure 13B , resin RS (reference Figure 12D ) can be filled into the first pattern GRU and the second pattern GRB by an inkjet method. Specifically, the inkjet head 1H and the nozzle NOZ can be disposed above the patterned glass PG". The nozzle NOZ can be disposed on the lower surface of the inkjet head 1H. The nozzle NOZ can be arranged in the second direction DR2.

[0162] The nozzle NOZ may discharge the resin RS. The nozzle NOZ may discharge the resin RS toward the first pattern GRU. Although not shown, after the resin RS is filled into the first pattern GRU, the nozzle NOZ may also discharge the resin RS toward the second pattern GRB.

[0163] When the nozzle NOZ discharges the resin RS toward the first and second patterns GRU and GRB, the amounts of the resin RS discharged to the respective first patterns GRU may be different from each other due to errors in the process, etc. Figure 13B As shown in FIG, the heights of the upper surfaces of the plurality of first filling resins FL1″ filled in the adjacent first patterns GRU may be different from each other. The heights of the upper surfaces of the plurality of second filling resins FL2″ filled in the adjacent second patterns GRB may be different from each other. Therefore, the upper surface PG-F″ and the lower surface PG-B″ of the patterned glass PG″ may become uneven, and the protective layer PLL (refer to FIG. Figure 7 ) and window adhesive layers W_AL1 and W_AL2 (refer to Figure 7 ) may be uneven. Therefore, the electronic device ED (refer to Figure 1 )’s surface quality may deteriorate.

[0164] Reference Figure 7 and Figure 12C , since the resin RS can be filled into the first pattern GRU and the second pattern GRB by capillary action, the height of the upper surface of the plurality of first filling resins FL1 can be the same. The height of the upper surface of the plurality of second filling resins FL2 can be the same. Therefore, the upper surface PG-F and the lower surface PG-B of the patterned glass PG can be flat. The protective layer PLL (refer to Figure 7 ) and window adhesive layers W_AL1 and W_AL2 (refer to Figure 7 ) can be flat. Therefore, the electronic device ED (refer to Figure 1 )’s surface quality can be improved.

[0165] Reference Figure 12CIn the embodiment, one patterned glass PG is shown in the water tank BK, but the present invention is not limited thereto, and thus a plurality of patterned glasses PG may be simultaneously disposed in the receiving groove SOP. That is, the resin RS may be simultaneously filled into the first pattern GRU and the second pattern GRB in the patterned glass PG. Therefore, the window WM (refer to FIG. 1 ) including the patterned glass PG Figure 3 )'s large-scale production capacity can be improved.

[0166] Reference Figure 12D , the water tank BKa may be provided above the patterned glass PG. The patterned glass PG and the water tank BKa may be connected to each other through a tube TBEa. Although not shown, an opening may be defined in the lower surface of the water tank BKa so that the resin RS can move toward the tube TBEa.

[0167] The resin RS accommodated in the accommodation groove SOPa can be directed toward the first pattern GRU (refer to Figure 12E ) and the second pattern GRB (refer to Figure 12E ) moves. Specifically, the resin RS can move along the inner surface of the tube TBEa by gravity and capillary action. The resin RS can be supplied to the patterned glass PG through the tube TBEa, and then the resin RS can be filled into the first pattern GRU and the second pattern GRB. The resin RS can be filled into the first pattern GRU and the second pattern GRB by capillary action and gravity.

[0168] In an embodiment of the present invention, the resin can be simultaneously filled into the grooves in the patterned glass by capillary action. Therefore, the resin can be uniformly filled into the pattern, thereby improving mass production capabilities.

[0169] In an embodiment of the present invention, the pattern may include a first groove defined in the upper surface of the window, a second groove extending from the first groove toward the lower surface of the window, a third groove defined in the lower surface of the window, and a fourth groove extending from the third groove toward the upper surface of the window. The width of the first groove may be smaller than the width of the second groove. The width of the third groove may be smaller than the width of the fourth groove. Since the first and third grooves having relatively small widths can be defined in the upper and lower surfaces of the window, respectively, the pattern may be invisible to the user, and thus, the display device may have improved surface quality.
