[0076] The specific structural and functional descriptions of the embodiments of the present invention disclosed herein are for illustrative purposes only. The present invention can be implemented in many different forms without departing from its spirit and distinctive features. Therefore, the embodiments of the present invention are disclosed for illustrative purposes only and should not be construed as limiting the invention. That is, the present invention is defined only by the scope of the claims.

[0077] It should be understood that when an element is referred to as being related to another element, such as when it is “connected” or “linked” to another element, the element may be directly connected to or linked to the other element, or there may be an intermediary element between them. Conversely, it should be understood that when an element is referred to as being related to another element, such as when it is “directly connected” or “directly linked” to another element, there is no intermediary element. Other expressions describing the relationship between elements, such as “between,” “directly between,” “proximately to,” or “directly adjacent to,” should be understood in the same manner.

[0078] Throughout the instruction manual, the same reference numerals will indicate the same or similar parts.

[0079] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, “first element,” “first component,” “first region,” “first layer,” or “first part” discussed below may be referred to as a second element, second component, second region, second layer, or second part without departing from the teachings herein.

[0080] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, “a,” “an,” “the,” and “at least one” do not indicate a limitation of quantity and are intended to include both singular and plural forms. For example, unless the context clearly indicates otherwise, “element” has the same meaning as “at least one element.” “At least one” should not be construed as limiting “a” or “an.” “Or” means “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It will also be understood that, when used in this specification, the terms “comprises” and / or “comprising” or “includes” and / or “including” specify the presence of the stated features, regions, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, regions, integrals, steps, operations, elements, components, and / or groups thereof.

[0081] Furthermore, relative terms such as “lower” or “bottom” and “upper” or “top” may be used herein to describe the relationship between one element and another as shown in the accompanying drawings. It will be understood that relative terms are intended to include different orientations of the device beyond those depicted in the drawings. For example, if a device in one of the drawings is flipped, an element described as being “below” the other elements will be oriented “above” the other elements. Thus, depending on the specific orientation of the drawing, the exemplary term “lower” may include both “lower” and “upper” orientations. Similarly, if a device in one of the drawings is flipped, an element described as being “below” or “under” the other elements will be oriented “above” the other elements. Thus, the exemplary term “below” or “under” may include both “upper” and “lower” orientations.

[0082] As used herein, “about” or “approximately” includes the value as well as the average of the values ​​within an acceptable range of deviations of a particular value, as determined by a person skilled in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the value.

[0083] Unless otherwise defined or indicated herein, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms, such as those defined in common dictionaries, shall be interpreted as having the same meaning as they have in the relevant field and in the context of this disclosure, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0084] Exemplary embodiments are described herein with reference to schematic cross-sectional views as examples of implementations. Thus, variations in the shapes shown in the figures should be anticipated, for example, due to manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be construed as being limited to the specific shapes of the regions shown herein, but should include, for example, deviations in shape due to manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, sharp corners shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0085] In the following description, embodiments of the invention will be described with reference to the accompanying drawings.

[0086] Figure 1 This is a schematic plan view of a guide film according to an embodiment of the present disclosure. Figure 2 It is along Figure 1 A schematic cross-sectional view taken by line I-I'.

[0113] In a plan view, the display panel 10 may have a rectangular shape with rounded corners. As another example, in a plan view, the display panel 10 may have a rectangular shape with right-angled corners, a square shape, a circular or elliptical shape, or a non-quadrilateral polygonal shape.

The main area of ​​display panel 10 may be positioned in the center of display panel 10, and the edge area of ​​display panel 10 may be positioned along the edge of the main area. Within the main area of ​​display panel 10, a main display area DA0 may be provided for displaying images. Pixels are required to display images. Therefore, pixels may be set within the main display area DA0.

The edge regions can be connected to the main display region DA0, or they can be integrated with the main display region DA0.

[0117] The outer contour of the first edge region may include a first contour, a second contour, and a third contour. The first contour has a convex shape with a first side facing the guide film GF in a first direction DR1 and a second side in a second direction DR2.

Figure 16 The first sub-non-display area NDA41, separated from the fourth display area DA4 by the first sub-non-display area NDA41. Figure 16 The second sub-non-display area NDA42, and the area separated from the first sub-non-display area NDA41 by the second sub-non-display area NDA42. Figure 16 The third non-display area NDA43.

[0124] The outer contour of the first sub-non-display area NDA41 may include a portion extending from the location where the seventh contour intersects with the fourth display area DA4 to the location where the seventh contour intersects with the eighth contour, and a portion extending from the location where the fifteenth contour intersects with the fourth display area DA4 to the location where the fifteenth contour intersects with the fourteenth contour.

[0126] The outer contour of the third sub-non-display area NDA43 may include the ninth contour, the tenth contour, the eleventh contour, the twelfth contour, and the thirteenth contour.

[0127] The first sub-non-display area NDA41, the second sub-non-display area NDA42, and the third sub-non-display area NDA43 may have different widths in the second direction DR2. For example, the width of the second sub-non-display area NDA42 in the second direction DR2 may be smaller than the widths of the first sub-non-display area NDA41 and the third sub-non-display area NDA43 in the second direction DR2.

[0128] The driver chip IC can be located in the third sub-non-display area NDA43. The driver chip IC may include a data integrated circuit (IC) and / or a sensing IC.

[0129] The printed circuit board (FPC) can be disposed at the end of the third sub-non-display area NDA43. The FPC may include a connector for electrical connection to an external device. The FPC can transmit various drive signals applied to it to the driver chip IC and / or each pixel in the display area of ​​the display panel 10 via the connector.

[0130] The main film portion GF0 can correspond to the main display area DA0 of the display panel 10, and the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can correspond to the first edge area, the second edge area, the third edge area, and the fourth edge area of ​​the display panel 10, respectively. The planar dimensions of the main film portion GF0 can be equal to the planar dimensions of the main display area DA0. The planar dimensions of the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can be larger than the planar dimensions of the first edge area, the second edge area, the third edge area, and the fourth edge area of ​​the display panel 10, respectively. The first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can be aligned with the boundaries between the main display area DA0 and the first edge area, the second edge area, the third edge area, and the fourth edge area, respectively. The fourth film portion GF4 can cover or overlap with the fourth edge area, and can cover or overlap with a portion of the driver chip IC and the printed circuit film FPC.

[0131] Reference Figure 5 The release film SF can be peeled off, and the main display area DA0, as well as the first edge area, second edge area, and third edge area, can be attached to the first connecting member 51. The fourth edge area, including the fourth display area DA4 and the fourth non-display area NDA4, can be attached to the second connecting member 52. (As...) Figure 5 As shown, due to the presence of the first UV absorption pattern GFS1 and the height difference with the second connecting member 52, the first connecting member 51 may be partially not attached to the main display area DA0 adjacent to the fourth edge region, and an empty space may be formed between the portion of the first connecting member 51 that is not attached to the main display area DA0 near the fourth edge region, the main display area DA0, the inner surface of the second connecting member 52, and the inner surface of the first UV absorption pattern GFS1.

[0132] The first connecting member 51 may include a UV-curable adhesive that can be cured by UV light. Therefore, if UV light is applied during the peeling of the entire guide film GF except for the fourth film portion GF4, the first connecting member 51 can be cured by UV light. Prior to the process of peeling off the entire guide film GF except for the fourth film portion GF4, a lamination process can be performed between the curved window and the curved display panel via the panel window connecting member. The panel window connecting member may include a UV-curable adhesive.

[0133] After the lamination process, a UV curing process for the panel window connecting member can be performed, and the first connecting member 51 can also be cured during the UV curing process of the panel window connecting member. For example, the first connecting member 51 can be cured not only by UV light from the UV curing process of the panel window connecting member, but also by UV light from the process of peeling off the entire guide film GF except for the fourth film portion GF4. Therefore, the adhesion between the curved display panel and the entire guide film GF except for the fourth film portion GF4 can be reduced, and the peeling off of the remaining portion of the guide film GF can be promoted. Since the notch line ICL is formed along the boundary between the fourth film portion GF4 and the main film portion GF0, the peeling off of the guide film GF can also be promoted.

[0134] Because the second connecting member 52 and the third connecting member 53 comprise a UV-non-curable adhesive, they may not be cured by UV light at all, or may only be slightly cured, during the UV curing process of the panel window connecting members and during the process of peeling off the entire guide film GF except for the fourth film portion GF4. Because the UV absorbing pattern GFS comprises a UV absorbing material, the UV absorbing pattern GFS can prevent UV light from reaching between the fourth film portion GF4 and the first UV absorbing pattern GFS1.

[0135] Therefore, even if UV light is applied until the UV absorption pattern GFS and the fourth film portion GF4 are removed, the first UV absorption pattern GFS1 can remain attached to the curved display panel, and the fourth film portion GF4 can remain attached to the first UV absorption pattern GFS1 and the second UV absorption pattern GFS2.

[0139] The second connecting member 52 may be omitted, and the peeling membrane SF may be in direct contact with the first surface of the membrane portions (GF0, GF1, GF2, GF3 and GF4).

[0140] In cases where the UV curing process of the panel window connector is omitted after the process of laminating the bent display panel and the bent window with the panel window connector is omitted, the guide film GF_1 can be used.

[0143] Reference Figure 8 The UV absorption pattern GFS can be configured to overlap with the main film portion GF0. In a planar view, the UV absorption pattern GFS can protrude beyond the fourth film portion GF4 towards the main film portion GF0. For example... Figure 8 As shown in the plan view, the width of the portion of the UV absorption pattern GFS that protrudes beyond the fourth film portion GF4 in the second direction DR2 can be equal to the width of the fourth film portion GF4 in the second direction DR2.

[0144] The UV absorption pattern GFS can be configured not to overlap with the first membrane portion GF1, the second membrane portion GF2, and the third membrane portion GF3.

[0145] Reference Figure 9 In the planar view, the width of the portion of the UV absorption pattern GFS that protrudes beyond the fourth film portion GF4 in the second direction DR2 can be less than the width of the fourth film portion GF4 in the second direction DR2.

[0146] Reference Figure 10 In the planar view, the width of the portion of the UV absorption pattern GFS that protrudes beyond the fourth film portion GF4 in the second direction DR2 can be greater than the width of the fourth film portion GF4 in the second direction DR2. The UV absorption pattern GFS can be configured to overlap with portions of the first film portion GF1 and the second film portion GF2.

[0147] Reference Figure 11 The planar dimensions of the UV absorption pattern GFS can be equal to the planar dimensions of the entire guiding film GF.

[0151] Subsequently, a cut line ICL can be formed along the boundary between the main membrane portion GF0 and the fourth membrane portion GF4. (The above has been referred to...) Figures 1 to 3 The cut line ICL is described, and therefore, a detailed description of it will be omitted.

[0152] Subsequently, refer to Figure 1 and Figure 2 A first connecting member 51 is provided on the first surface (or top surface) of the membrane portions (GF0, GF1, GF2, GF3, and GF4). Subsequently, a first UV absorption pattern GFS1 can be formed to overlap the fourth membrane portion GF4 in the thickness direction of the guiding membrane GF via the first connecting member 51, and a second UV absorption pattern GFS2 can be formed on the second surface (or bottom surface) of the fourth membrane portion GF4. The second UV absorption pattern GFS2 can be attached to the second surface (or bottom surface) of the fourth membrane portion GF4 via a third connecting member 53. A second connecting member 52 can be formed on the second surface of the first UV absorption pattern GFS1 opposite to the first surface to which the first connecting member 51 is attached. A release film SF can be provided on the first connecting member 51 and the second connecting member 52 exposed by the first UV absorption pattern GFS1.

[0153] In the following, a method for manufacturing a display device according to embodiments of the present disclosure will be described. In the foregoing and the following embodiments, the same elements refer to the same elements, and therefore, their description will be omitted or simplified.

[0154] A method of manufacturing a display device may include bending a display panel by using a guide film GF (or by using a guide film GF), laminating a bent window onto the bent display panel, and attaching a panel substrate to a second surface of the bent display panel, the second surface being opposite to a first surface of the bent display panel on which the bent window is laminated. A portion of the guide film GF may not be removed to prevent the bent portion of the bent display panel from unsuitably bending during the manufacture of the display device, and this will be described below.

[0155] Figure 14 This is a schematic flowchart illustrating a method for manufacturing a display device according to an embodiment of the present disclosure. Figure 15 , Figure 17 as well as Figures 19 to 27 It is shown Figure 14 A schematic 3D diagram illustrating the method. Figure 16 It is shown Figure 15 A schematic plan view of the fourth non-display area, driver chip, and printed circuit film of the display panel. Figure 18 yes Figure 17 A schematic cross-sectional view of the structure shown.

[0156] Reference Figures 14 to 16 Step S10: Prepare display panel 10. Display panel 10 includes a main display area DA0, a first edge area, a second edge area, a third edge area, and a fourth edge area surrounding the main display area DA0, a driver chip IC disposed in a first pad area PA1 of the fourth edge area, and a printed circuit film FPC attached to a second pad area PA2 of the fourth edge area. The first pad area PA1 and the second pad area PA2 can be positioned in a third sub-non-display area NDA43. As described below, the second sub-non-display area NDA42 can be bent in the thickness direction of the guide film GF. When the second sub-non-display area NDA42 is bent, the first sub-non-display area NDA41 and the third sub-non-display area NDA43 can be arranged to overlap each other in the thickness direction of the guide film GF. (See above for reference.) Figure 4 and Figure 5 The display panel 10 is described, and therefore a detailed description thereof will be omitted.

[0157] Subsequently, refer to Figure 14 , Figure 17 and Figure 18 The guide film GF is placed on the support device 30, and the display panel 10 is placed on the guide film GF on the support device 30 (step S20).

[0158] The support device 30 may include a first clamping member CL1, a second clamping member CL2, a third clamping member CL3 and a fourth clamping member CL4, a first guide roller GR1, a second guide roller GR2, a third guide roller GR3 and a fourth guide roller GR4 respectively connected to the first clamping member CL1, the second clamping member CL2, the third clamping member CL3 and the fourth clamping member CL4, a platform ST disposed below the guide film GF and a forming pad SP.

[0159] The support device 30 and the guide film GF can be parts of an apparatus for manufacturing a display device, which is used in a method for manufacturing a display device. In other words, the apparatus for manufacturing a display device may include the support device 30 and the guide film GF.

[0160] The stage ST may include a first stage ST1 as the bottommost stage ST and a second stage ST2 disposed above the first stage ST1. A molding pad SP may be disposed above the second stage ST2. The molding pad SP and the second stage ST2 may have a rectangular shape in plan view. The planar dimensions of the molding pad SP may be substantially equal to the planar dimensions of the second stage ST2. Each of the molding pad SP and the second stage ST2 may include a pair of long sides extending in a first direction DR1 and a pair of short sides extending in a second direction DR2. The second short sides of the molding pad SP and the second stage ST2 in the first direction DR1 may be covered by or overlap with the first stage ST1, but the first short sides of the molding pad SP and the second stage ST2 in the first direction DR1 may not be covered by or overlap with the first stage ST1 and may be exposed. In the case of a bent display panel 10, the printed circuit film FPC attached to the fourth edge region of the display panel 10 may extend toward the second side of the display panel 10 in a third direction DR3. However, since the first short side of the forming pad SP and the second ST2 does not overlap with the first ST1 and is exposed, interference between the printed circuit film FPC and the first ST1 can be prevented when the printed circuit film FPC extends toward the second side of the display panel 10 on the third-direction DR3.

[0161] The molding pad SP may include a flexible material. The molding pad SP may include, for example, rubber or a fluid material.

[0162] The main film portion GF0 of the guide film GF can be configured to overlap with the forming pad SP in the thickness direction of the guide film GF. The main film portion GF0 can be configured to completely overlap with the forming pad SP, and the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 of the guide film GF can be configured not to overlap with the forming pad SP in the thickness direction of the guide film GF.

[0163] The first membrane portion GF1, the second membrane portion GF2, the third membrane portion GF3, and the fourth membrane portion GF4 can be fixed by the first clamping member CL1, the second clamping member CL2, the third clamping member CL3, and the fourth clamping member CL4, respectively. The first clamping member CL1, the second clamping member CL2, the third clamping member CL3, and the fourth clamping member CL4 can be respectively disposed on the first surface (or top surface) and the second surface (or bottom surface) of the end portions of the first membrane portion GF1, the second membrane portion GF2, the third membrane portion GF3, and the fourth membrane portion GF4, and thus can fix the first membrane portion GF1, the second membrane portion GF2, the third membrane portion GF3, and the fourth membrane portion GF4, respectively.

[0164] The first clamping member CL1 and the second clamping member CL2 can extend in the first direction DR1, and the third clamping member CL3 and the fourth clamping member CL4 can extend in the second direction DR2.

[0165] The first clamping member CL1 can fix the first film portion GF1 from both the first and second surfaces of the first film portion GF1, while stretching the first film portion GF1 toward the second side of the guide film GF in the second direction DR2 (or applying tension to the first film portion GF1). The second clamping member CL2 can fix the second film portion GF2 from both the first and second surfaces of the second film portion GF2, while stretching the second film portion GF2 toward the first side of the guide film GF in the second direction DR2. The third clamping member CL3 can fix the third film portion GF3 from both the first and second surfaces of the third film portion GF3, while stretching the third film portion GF3 toward the second side of the guide film GF in the first direction DR1. The fourth clamping member CL4 can fix the fourth film portion GF4 from both the first and second surfaces of the fourth film portion GF4, while stretching the fourth film portion GF4 toward the first side of the guide film GF in the first direction DR1.

[0166] The first guide roller GR1, the second guide roller GR2, the third guide roller GR3, and the fourth guide roller GR4 can be connected to the first clamping member CL1, the second clamping member CL2, the third clamping member CL3, and the fourth clamping member CL4, respectively. The first guide roller GR1 can be connected to the first clamping member CL1 and can be disposed on the first surface (or top surface) of the first film portion GF1. The first guide roller GR1 can be disposed between the first clamping member CL1 and the main film portion GF0. The first guide roller GR1 can extend in the first direction DR1. The second guide roller GR2 can be connected to the second clamping member CL2 and can be disposed on the first surface (or top surface) of the second film portion GF2. The second guide roller GR2 can be disposed between the second clamping member CL2 and the main film portion GF0. The second guide roller GR2 can extend in the first direction DR1. The third guide roller GR3 can be connected to the third clamping member CL3 and can be disposed on the first surface (or top surface) of the third film portion GF3. The third guide roller GR3 can be disposed between the third clamping member CL3 and the main film portion GF0. The third guide roller GR3 can extend in the second direction DR2. The fourth guide roller GR4 can be connected to the fourth clamping member CL4 and can be disposed on the first surface (or top surface) of the fourth film portion GF4. The fourth guide roller GR4 can be disposed on the first surface (or top surface) of the first UV absorption pattern GFS1.

[0167] The fourth guide roller GR4 can be positioned between the fourth clamping member CL4 and the main film section GF0.

[0168] The fourth guide roller GR4 can extend in the second direction DR2.

[0169] The display panel 10 can be disposed on the guide film GF. The main film portion GF0 can be configured to correspond to the main display area DA0 of the display panel 10, and the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can be configured to correspond to the first edge area, the second edge area, the third edge area, and the fourth edge area of ​​the display panel 10, respectively. The planar dimensions of the main film portion GF0 can be equal to the planar dimensions of the main display area DA0. The planar dimensions of the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can be larger than the planar dimensions of the first edge area, the second edge area, the third edge area, and the fourth edge area of ​​the display panel 10, respectively. The first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can be aligned with the boundaries between the main display area DA0 of the display panel 10 and the first edge area, the second edge area, the third edge area, and the fourth edge area, respectively. The fourth film portion GF4 can cover or overlap with the fourth edge area, and can partially overlap with the driver chip IC and the printed circuit film FPC disposed in the fourth edge area.

[0170] The main display area DA0, as well as the first edge area, the second edge area, and the third edge area, can be attached to the first connecting member 51. The fourth edge area, including the fourth display area DA4 and the fourth non-display area NDA4, can be attached to the second connecting member 52.

[0171] Subsequently, refer to Figure 14 and Figure 19 The display panel 10 can be bent to obtain a bent display panel 10 (step S30).

[0172] Step S30 can be performed using a guide film GF. Specifically, the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 can be lowered by using first guide rollers GR1, second guide rollers GR2, third guide rollers GR3, and fourth guide rollers GR4 respectively connected to the first clamping member CL1, the second clamping member CL2, the third clamping member CL3, and the fourth clamping member CL4, and the first edge region, the second edge region, the third edge region, and the fourth edge region of the display panel 10 can be bent from the main display area DA0 to form a curved display panel 10. The regions of the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 extending from the main film portion GF0 to the first guide roller GR1, the second guide roller GR2, the third guide roller GR3, and the fourth guide roller GR4 can extend in the third direction DR3 (or the thickness direction of the guide film GF), and the regions of the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 extending from the first guide roller GR1, the second guide roller GR2, the third guide roller GR3, and the fourth guide roller GR4 to the ends (or portions) of the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 fixed by the first clamping member CL1, the second clamping member CL2, the third clamping member CL3, and the fourth clamping member CL4 can extend in the second direction DR2 or the first direction DR1.

[0173] according to Figure 14 In this method, the first, second, third, and fourth edge regions of the display panel 10 can be pre-deformed before the curved window 50 is laminated onto the display panel 10. Therefore, it is possible to prevent the first, second, third, and fourth edge regions of the display panel 10, which extend in the horizontal direction (i.e., the first direction DR1 or the second direction DR2), from contacting the curved window 50 and thus avoiding physical damage due to the curved window 50.

[0174] Subsequently, refer to Figure 14 , Figure 20 and Figure 21 The curved window 50 is laminated onto the curved display panel 10 via the panel window connecting member 54 (step S40).

[0175] The curved window 50 may include a main window area corresponding to the main display area DA0 of the curved display panel 10 and a window edge area corresponding to the edge area of ​​the curved display panel 10. The curved window 50 may have a three-dimensional shape that is substantially the same as the three-dimensional shape of the curved display panel 10. In a plan view, the main window area of ​​the curved window 50 may be arranged to overlap with the main display area DA0 of the curved display panel 10 and may have a size substantially equal to that of the main display area DA0. In a plan view, the window edge area of ​​the curved window 50 may have a larger size than the edge area of ​​the curved display panel 10 and may overlap with the edge area of ​​the curved display panel 10 from outside the edge area of ​​the curved display panel 10.

[0176] like Figure 21 As shown, step S40 may include placing the panel window connecting member 54 on the curved display panel 10, placing the curved window 50 on the curved display panel 10 (i.e., on the first side of the curved display panel 10 in the third direction DR3), and laminating the curved window 50 and the curved display panel 10 together via the panel window connecting member 54 by using the laminating device 70 (or by using the laminating device 70). Once pressure is applied to the first surface (or top surface) of the curved window 50 with the laminating device 70, the main window area of ​​the curved window 50 and the main display area DA0 of the curved display panel 10 can be joined together initially, and due to the pressure applied via the laminating device 70, the flexible material from the forming pad SP of the support device 30 can move in the horizontal direction (i.e., the first direction DR1 and / or the second direction DR2). Therefore, the window edge area of ​​the curved window 50 and the edge area of ​​the curved display panel 10 can be joined together.

[0177] The panel window connection member 54 may include an adhesive that can be cured by UV light. The panel window connection member 54 may include, for example, a UV-curable optically clear connection member. Examples of UV-curable optically clear connection members may include optically clear adhesives and optically clear resins, but this disclosure is not limited thereto.

[0178] Subsequently, refer to Figure 14 and Figure 22 The panel window connecting member 54 is cured by applying a first light L1 to the first surface (or top surface) of the curved window 50 laminated on the curved display panel 10 (step S50). The first light L1 can be light in the UV wavelength range. When the first light L1 is applied, the panel window connecting member 54 can be UV cured.

[0179] During the UV curing of the panel window connecting member 54, the first connecting member 51 can be cured by the first light L1. Therefore, the adhesion between the curved display panel 10 and the main film portion GF0, the first film portion GF1, the second film portion GF2, and the third film portion GF3 of the guide film GF can be reduced.

[0180] Conversely, since the second connecting member 52 comprises a UV-non-curable adhesive, it can remain completely uncured or only slightly cured by the applied UV light during the UV curing of the panel window connecting member 54. Therefore, the adhesion between the first UV-absorbing pattern GFS1 and the curved display panel 10 can be maintained. Because the first UV-absorbing pattern GFS1 comprises a UV-absorbing material, it can prevent UV light from reaching the first connecting member 51 between the fourth film portion GF4 and the first UV-absorbing pattern GFS1.

[0181] Therefore, even if UV light continues to be applied until the fourth film portion GF4 and the UV absorption pattern GFS including the first UV absorption pattern GFS1 and the second UV absorption pattern GFS2 are removed, the first UV absorption pattern GFS1 can remain attached to the curved display panel 10, and the fourth film portion GF4 can remain attached to the first UV absorption pattern GFS1.

[0182] Subsequently, refer to Figure 14 , Figure 23 and Figure 24 Remove the entire guide membrane GF except for the fourth membrane portion GF4 (step S60).

[0183] like Figure 23 As shown, step S60 can be performed when the structure including the guide film GF, the curved display panel 10, the panel window connecting member 54, and the curved window 50 is inverted on the third direction DR3. When the structure is inverted on the third direction DR3, the direction in which the first film portion GF1, the second film portion GF2, the third film portion GF3, and the fourth film portion GF4 extend from the main film portion GF0 can be the third direction DR3, and the curved display panel 10 can be positioned above the curved window 50.

[0184] like Figure 24 As shown, step S60 can be performed by applying a second light L2 from above the curved display panel 10. The second light L2 can be light in the UV wavelength range.

[0185] In step S60, the first connecting member 51 can be cured by applying a second light L2 during the removal of the main film portion GF0, the first film portion GF1, the second film portion GF2, and the third film portion GF3 of the guide film GF. Therefore, the adhesion between the curved display panel 10 and the main film portion GF0, the first film portion GF1, the second film portion GF2, and the third film portion GF3 of the guide film GF can be reduced.

[0186] Conversely, since the third connecting member 53 comprises a UV-non-curable adhesive, the third connecting member 53 may remain completely uncured or only slightly cured by the applied second light L2 during the removal of the main film portion GF0 of the guiding film GF, as well as the first film portion GF1, the second film portion GF2, and the third film portion GF3 (i.e., step S60). Therefore, the adhesion between the second UV-absorbing pattern GFS2 and the curved display panel 10 can be maintained. Because the second UV-absorbing pattern GFS2 comprises a UV-absorbing material, it can prevent UV light from reaching the first connecting member 51.

[0187] In steps S50 and S60, the first connecting member 51 can be cured, thereby reducing the adhesion between the curved display panel 10 and the guide film GF. Therefore, there is no adhesion, or only slight adhesion, between the curved display panel 10 and the guide film GF. Thus, as mentioned above, the main film portion GF0 of the guide film GF, as well as the first film portion GF1, the second film portion GF2, and the third film portion GF3, can be easily separated and peeled from the fourth film portion GF4 along the cut line ICL formed at the boundary between the fourth film portion GF4 and the main film portion GF0.

[0188] The first UV absorption pattern GFS1 can remain attached to the fourth edge region of the curved display panel 10, the fourth film portion GF4 can remain attached to the first UV absorption pattern GFS1, and the second UV absorption pattern GFS2 can remain attached to the fourth film portion GF4.

[0189] Subsequently, refer to Figure 14 and Figure 25 The panel substrate PLM is attached to the top surface of the curved display panel 10 (or disposed on the top surface of the curved display panel 10), which is opposite to the surface of the curved display panel 10 to which the curved window 50 is attached (step S70).

[0190] The panel backing film PLM can be attached to the main display area DA0 of the curved display panel 10. The panel backing film PLM may include at least one functional layer. The functional layer may be a layer that performs heat dissipation, electromagnetic wave shielding, grounding, buffering, strength enhancement, support, and / or digitization functions. The functional layer may be a sheet, film, thin film layer, coating, panel, or plate. The functional layer may be formed as a single layer or a stack of multiple thin film layers or coatings. The functional layer may be, for example, a support member, a heat dissipation layer, an electromagnetic wave shielding layer, a shock absorption layer, or a digitizer.

[0191] Subsequently, refer to Figure 14 and Figure 26 Remove the fourth film portion GF4 and the UV absorption pattern GFS from the curved display panel 10 (step S80).

[0192] The second connecting member 52 has a weak adhesive bond between the first UV absorption pattern GFS1 and the fourth edge region of the curved display panel 10. Therefore, the first UV absorption pattern GFS1 can be easily removed from the fourth edge region of the curved display panel 10.

[0193] After removing the main film portion GF0 and the first film portion GF1, the second film portion GF2, and the third film portion GF3 (i.e., step S60), until the second sub-non-display area NDA42, which is the curved portion of the curved display panel 10, is bent, the first UV absorption pattern GFS1 can remain attached to the fourth edge region of the curved display panel 10, the fourth film portion GF4 can remain attached to the first UV absorption pattern GFS1, and the second UV absorption pattern GFS2 can remain attached to the fourth film portion GF4. Therefore, after removing the main film portion GF0 and the first film portion GF1, the second film portion GF2, and the third film portion GF3, it is possible to prevent the second sub-non-display area NDA42 of the curved display panel 10 from unsuitably bending.

[0194] After step S60 and before step S70, if the second sub-non-display area NDA42 of the bent display panel 10 is bent, the signal line passing through the second sub-non-display area NDA42 (i.e., from...) Figure 15 and Figure 16 The signal lines (DA0, DA1, DA2, DA3, and DA4) passing through the first pad area PA1 in the display area may break and / or may become disconnected. However, in Figure 14In the method, after step S60, since the first UV absorption pattern GFS1 remains attached to the fourth edge region of the curved display panel 10 until the second sub-non-display area NDA42, which is the curved portion of the curved display panel 10, is bent, the fourth film portion GF4 remains attached to the first UV absorption pattern GFS1, and the second UV absorption pattern GFS2 remains attached to the fourth film portion GF4, it is possible to prevent the second sub-non-display area NDA42 of the curved display panel 10 from bending unsuitably.

[0195] Subsequently, refer to Figure 14 and Figure 27 The second sub-non-display area NDA42, which is the curved portion of the curved display panel 10, is bent (step S90). The second sub-non-display area NDA42, which is the curved portion of the curved display panel 10, is bent in the thickness direction of the guide film GF. In this case, the first sub-non-display area NDA41 and the third sub-non-display area NDA43 can be arranged to overlap each other in the thickness direction of the guide film GF. The printed circuit film FPC disposed in the third sub-non-display area NDA43 can be arranged to overlap with the main display area DA0.

[0196] In the following, a method for manufacturing a display device according to another embodiment of the present disclosure will be described.

[0197] Figures 28 to 30 This is a schematic perspective view illustrating a method for manufacturing a display device according to an embodiment of the present disclosure.

[0198] exist Figures 28 to 30 In the method, you can use Figure 6 The guiding membrane GF_1.

[0199] Figures 28 to 30 Methods and Figure 14 The difference in the method is at least that the first UV absorption pattern GFS1 is not set, and after attaching the panel film PLM (i.e. step S70), the second UV absorption pattern GFS2 is removed from the fourth film portion GF4, and then the fourth film portion GF4 is removed by applying the second light L2.

[0200] From Figures 28 to 30 The method omits the UV curing of the panel window connecting member 54. Therefore, it is not necessary to provide protection against UV curing applied in the top-to-bottom direction. Figure 22 The first light L1 reaches the first UV absorption pattern GFS1 at the first connecting member 51.

[0201] will be omitted Figures 28 to 30 Description of other aspects or features of the method.

[0202] Although embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will understand that various modifications, additions, and substitutions may be made without departing from the scope and spirit of the invention as disclosed in the appended claims.
