[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
It should be understood that although the terms first, second, third, etc. may be used to describe the hollowed-out areas in embodiments of the present invention, the hollowed-out areas should not be limited by these terms. These terms are only used to distinguish the hollowed-out areas from each other. For example, the first hollow-out area may also be referred to as a second hollow-out area, and similarly, the second hollow-out area may also be referred to as a first hollow-out area without departing from the scope of the embodiments of the present invention.
As shown in fig. 1, fig. 1 is a schematic cross-sectional view of a display module in the prior art, wherein the display module includes a folding region B 'and a non-folding region a'. In order to protect the display module and improve and enrich the performance of the display module, various functional layers 2 'such as polarizers and the like are usually attached to the flexible display panel 1'. At present, the display panel 1 ' and the functional layer 2 ' are usually bonded by using a glue material 3 '. However, in the research process, the inventor of the present application finds that after the display module is repeatedly bent for a plurality of times, the functional layer 2 'in the display module is degummed after the display module is restored from the bent state to the unfolded state, that is, after the folding region B' of the display module is restored to the unfolded state.
Through a large number of experiments and researches, the inventor of the present invention finds that, because the rubber material 3 ' belongs to a viscoelastic body, the strain lags behind the stress in the deformation process, that is, after the display module returns from the bending state to the unfolding state, the strain generated in the bending deformation process of the rubber material 3 ' in the folding region B ' cannot be restored in time. Moreover, since the glue material 3 'is generally a whole layer structure, the glue material 3' located at a position close to the folding region B 'in the non-folding region a' is also deformed to some extent along with the bending of the glue material 3 'located at the folding region B'. However, when the display module is bent, the deformation degree of the adhesive material 3 'at the position is different between the side close to the folding area B' and the side close to the non-folding area a 'because the adhesive material 3' at the starting position of the display module, i.e. the boundary area between the folding area B 'and the non-folding area a' is stressed differently between the side close to the folding area B 'and the side close to the non-folding area a'. After the display module is restored to the unfolded state, the restoration degree of the glue material 3 ' at the position is also greatly different between the side close to the folding area B ' and the side close to the non-folding area a '. Therefore, gathering or thinning of the glue material 3 'easily occurs at this position, resulting in a wrinkle-like defect of the glue material 3' at this position. This problem not only influences the outward appearance of display module assembly, moreover, the fold still can exert a peeling force who keeps away from gluey material 3 ' to the functional layer 2 ' of gluing material 3 ' bonding, leads to functional layer 2 ' to take place the phenomenon of coming unstuck easily, influences display module assembly's performance.
Based on this, an embodiment of the present invention provides a display module, as shown in fig. 2, fig. 2 is a schematic top view of the display module in an unfolded state, where the display module includes at least one folding area 11 and at least two non-folding areas 12, the folding area 11 and the non-folding areas 12 are arranged along a first direction x, and the folding area 11 is located between two adjacent non-folding areas 12.
As shown in fig. 3, fig. 3 is a schematic cross-sectional view along DD' of fig. 2, wherein the display module further includes a flexible display panel 2, and the flexible display panel 2 includes a first side 21 and a second side 22 oppositely disposed along a thickness direction thereof, i.e., a third direction z.
The display module further comprises at least one functional layer 3 and at least one glue layer 4. Wherein at least one of said functional layers 3 is located on a first side 21 of the flexible display panel 2. Of course, in addition to the functional layer 3 located at the first side 21 of the flexible display panel 2, the functional layer 3 may also be provided at the second side 22 of the flexible display panel 2. In fig. 3 it is illustrated that a functional layer 3 is provided on both the first side 21 and the second side 22 of the flexible display panel 2.
For example, the adhesive layer 4 may be disposed at a plurality of positions in the display module, for example, as shown in fig. 3, the adhesive layer 4 may be disposed at a side of the functional layer 3 close to the flexible display panel 2, that is, the adhesive layer 4 is disposed between the functional layer 3 and the flexible display panel 2. Alternatively, as shown in fig. 4, fig. 4 is another schematic cross-sectional view along DD' of fig. 2, wherein at least one glue layer 4 may also be disposed on the side of the functional layer 3 away from the flexible display panel 2.
As shown in fig. 3 and 4, the glue layer 4 includes a hollowed-out area 40; the hollow-out area 40 at least includes a first hollow-out area 41, and the first hollow-out area 41 is located at a boundary area between the folding area 11 and the non-folding area 12. That is, the first hollow area 41 overlaps with the boundary area between the folding area 11 and the non-folding area 12. That is, the first hollow area 41 may be located in the boundary area entirely, or a part of the first hollow area 41 may be located in the boundary area, and another part is located in the folding area 11 or the non-folding area 12.
As shown in fig. 2, the folding area 11 of the display module includes a folding axis 110, and the folding axis 110 extends along a second direction y, which intersects with the first direction x. When the display module is folded, for example, when the folding direction of the display module is the same as the direction from the first side 21 to the second side 22 of the flexible display panel 2, the folding region 11 can be folded along the folding axis 110 to the states shown in fig. 5 and 6, fig. 5 is a schematic top view of the display module in the folded state according to the embodiment of the present invention, and fig. 6 is a schematic cross-sectional view along EE' of fig. 5. Alternatively, when the bending direction of the display module is the same as the direction in which the second side 22 of the flexible display panel 2 points to the first side 21, the folding region 11 can be bent along the folding axis 110 to the states shown in fig. 7 and 8, fig. 7 is a schematic top view of another display module in a folded state according to an embodiment of the present invention, and fig. 8 is a schematic cross-sectional view along GG' of fig. 7.
In the display module provided in the embodiment of the present invention, the portion of the adhesive layer 4 located in the boundary area between the folding area 11 and the non-folding area 12 is removed, that is, the first hollow area 41 is disposed in the adhesive layer 4 corresponding to the boundary area between the folding area 11 and the non-folding area 12. When the display module is folded, as shown in fig. 6 and 8, the portion of the adhesive layer 4 located in the first hollow area 41 does not have the adhesive layer 4, and thus, the portion of the adhesive layer 4 located in the first hollow area 41 does not deform. Furthermore, when the display module is restored to the unfolding state shown in fig. 3 and 4 from the folding state, the problem of gathering or thinning of the adhesive layer 4 caused by inconsistent deformation degree of the adhesive layer 4 at one side close to the folding area and one side close to the non-folding area and inconsistent restoration degree can be avoided. Therefore, after the display module provided by the embodiment of the invention is repeatedly folded for many times and is restored to the unfolded state, the flatness of the glue layer 4 can be improved, the adhesiveness between the glue layer 4 and the functional layer 3 adhered to the glue layer is ensured, and the problems of degumming and the like of the functional layer 3 are avoided.
It should be noted that, in the top views shown in fig. 2, 5 and 7, other film layers such as the functional layer 3 except the glue layer 4 are not shown in order to clearly illustrate the positions of the hollowed-out regions 40 in the glue layer 4.
For example, the first side 21 may be a backlight side of the flexible display panel, and the first hollow area 41 is formed by removing the adhesive layer 4 on the backlight side of the display panel, so as to avoid affecting the optical characteristics of the display module.
For example, when the first side 21 is used as the light emitting side of the flexible display panel 2, that is, when the hollow area 40 including the first hollow area 41 is disposed on the light emitting side of the flexible display panel, the hollow area 40 may be filled with resin to avoid affecting the optical characteristics of the display module. For example, a resin material with high transmittance and easy lift recovery can be selected for filling.
Alternatively, the resin may be formed by printing or coating.
For example, the position of the first hollow area 41 in the glue layer 4 may have various designs, which are described below:
fig. 9 is a schematic cross-sectional view along DD' of fig. 2, wherein an edge 410 of the first hollow area 41 near the non-folded area 12 overlaps with a boundary line between the folded area 11 and the non-folded area 12, as shown in fig. 9. The first cutout region 41 extends from the boundary between the folded region 11 and the unfolded region 12 toward the folded region 11, and the portion of the adhesive layer 4 located in the unfolded region 12 is not removed, so that the flatness of the adhesive layer 4 is improved, and the adhesiveness between the adhesive layer 4 located in the unfolded region 12 and the functional layer 3 to which the adhesive layer 4 is adhered can be ensured.
Fig. 10 is a schematic cross-sectional view along DD' of fig. 2, wherein the first hollow area 41 is located at the non-folding area 12, and an edge 510 of the first hollow area 41 close to the folding area 11 overlaps with a boundary 10 between the folding area 11 and the non-folding area 12. The first cutout region 41 is extended from the boundary 10 between the folded region 11 and the non-folded region 12 toward the non-folded region 12, and the portion of the adhesive layer 4 located in the folded region 11 is not removed. With this arrangement, the adhesive property of the adhesive layer 4 located in the folding region 11 and the functional layer 3 to which the adhesive layer 4 is bonded can be ensured on the basis of improving the flatness of the adhesive layer 4. Moreover, in this case, even if the adhesive layer 4 in the folding area 11 is gathered, the first hollow area 41 can also serve as a space for accommodating the gathered adhesive layer 4, so that the adhesive layer 4 can be prevented from gathering in the thickness direction thereof to form wrinkles, and the flatness of the adhesive layer 4 can be further improved.
As described above, fig. 9 and 10 correspond to the positions of the first hollow area 41, which are illustrated by taking the first hollow area 41 extending from the boundary between the folded area 11 and the non-folded area 12 toward the folded area 11 or the non-folded area 12, as an example. In fact, it is also possible to make the first hollowed-out area 41 extend from the boundary of the folding area 11 and the non-folding area 12 to both sides of the folding area 11 and the non-folding area 12, that is, to make the first hollowed-out area 41 include both a portion overlapping with the folding area 11 and a portion overlapping with the non-folding area 12. Specifically, as shown in fig. 3, at this time, the first hollow area 41 includes a first portion 411 and a second portion 412, the first portion overlaps with the folding area 11, and the second portion overlaps with the non-folding area 12.
As shown in fig. 3, the boundary line 10 between the folded region 11 and the non-folded region 12 extends in the third direction z in a plane passing through the first direction x and the third direction z. Further, the boundary 10 passes through the inside of the first hollow area 41 in the third direction z. With this arrangement, the areas of the first portion 411 and the second portion 412 can be set small to compromise the adhesion of the glue layer 4 located in the folded region 11 and the unfolded region 12 to the functional layer 3 to which it is adhered.
When only one hollow area is disposed in the adhesive layer 4, as shown in fig. 11 and 12, fig. 11 is a schematic top view of another display module in a folded state according to an embodiment of the present invention, and fig. 12 is a schematic cross-sectional view along GG' of fig. 11, wherein the shape and area of the hollow area may be set to be the same as that of the folded area 11, that is, the edge 410 of the first hollow area 41 near the non-folded area 12 is set to overlap with the boundary 10 of the folded area 11 and one of the non-folded areas 12, and the edge 510 of the first hollow area 41 near the folded area 11 is set to overlap with the boundary 10 of the folded area 11 and the other non-folded area 12.
Alternatively, as shown in fig. 13 and 14, fig. 13 is a schematic top view of another display module in a folded state according to an embodiment of the present invention, and fig. 14 is a schematic cross-sectional view along HH' of fig. 13, wherein the area of the hollow area can be set to be larger, so that the hollow area penetrates through the folding area 11 and extends into the non-folding areas 12, that is, the edge 410 of the first hollow area 41 close to the non-folding area 12 is set in one of the non-folding areas 12, and the edge 510 of the first hollow area 41 close to the folding area 11 is set in the other non-folding area 12. It will be appreciated that the removal of the entire glue layer in the fold region 11 avoids the problem of glue layer gathering or thinning during repeated bending of the fold region 11.
In the embodiment of the present invention, the number of the first hollow-out areas 41 may be set to be at least two, and the at least two first hollow-out areas 41 are respectively located on two opposite sides of the folding area 11 in the first direction x. For example, as shown in fig. 15, fig. 15 is a schematic cross-sectional view of another display module in an unfolded state according to an embodiment of the present invention, where the cross section is parallel to a plane passing through a first direction x and a third direction z, and the number of the first hollow-out regions 41 is two, and one of the first hollow-out regions 41 is located at a boundary region between the folding region 11 and one of the non-folding regions 12, and the other first hollow-out region 41 is located at a boundary region between the folding region 11 and the other non-folding region 12, so as to improve a problem of aggregation or thinning of a glue layer that may occur at the boundary region between the two non-folding regions 12 and the folding region 11. Exemplarily, as shown in fig. 15, in the first direction x, a distance d1 between two first hollow areas 41 is greater than zero.
Alternatively, the two first hollow-out areas 41 may be set to have equal shapes and sizes, and the two first hollow-out areas 41 may have equal distances from the center line 6 of the folding area 11, that is, the first hollow-out areas 41 may be set to be symmetrical with respect to the center line 6 of the folding area 11, so that the two first hollow-out areas 41 may have a consistent effect on improving the gathering or thinning problem of the adhesive layer at the boundary area between the two non-folding areas 12 and the folding area 11. Wherein the central line 6 of the folding area 11 is a straight line passing through the center of the folding area 11 and extending in the third direction z.
It should be noted that, when the plurality of first hollow-out regions 41 are provided, the edge 510 of the plurality of first hollow-out regions 41 close to the folding region 11 may be arranged to overlap with the boundary 10 between the folding region 11 and the non-folding region 12, which is shown in fig. 15. Of course, as mentioned above, the plurality of first hollow-out regions 41 may be arranged in the manner shown in fig. 9, that is, the edge 410 of the plurality of first hollow-out regions 41 close to the non-folding region 12 is arranged to overlap with the boundary 10 between the folding region 11 and the non-folding region 12. Alternatively, in the manner shown in fig. 3, each of the plurality of first hollow-out regions 41 may be provided to include a portion overlapping with the folding region 11 and a portion overlapping with the non-folding region 12, and the boundary 10 between the folding region 11 and the non-folding region 12 may be made to pass through the inside of the plurality of first hollow-out regions 41 in the extending direction of the boundary 10.
As shown in fig. 16, fig. 16 is a further schematic cross-sectional view along DD' of fig. 2, wherein the hollowed-out region 40 further includes a second hollowed-out region 42, the second hollowed-out region 42 is located in the folding region 11, and a distance d2 between the second hollowed-out region 42 and the first hollowed-out region 41 in the first direction x is greater than zero. On one hand, the problem of aggregation or thinning of the adhesive layer 4 caused by slow deformation and deformation recovery of the adhesive layer 4 is better solved; on the other hand, compare in the technical scheme that the glue film that will fold region 11 is whole to be got rid of, this scheme remains a part glue film in fold region 11, has increased the adhesion between functional layer 3 and the flexible display panel 2, makes the adhesion of each layer more firm in the display module assembly.
Fig. 17 and 18 show a top view of another display module in an unfolded state according to an embodiment of the invention, and fig. 18 shows a cross-sectional view along FF' of fig. 17, in which the hollow area further includes a second hollow area 42, and the second hollow area 42 is at least partially located in the folding area 11. And, the folding shaft 110 passes through the second hollowed-out area 42. Since the stress of the layer of glue 4 at the location of the folding axis 110 of the folding area 11 is greatest at the moment of bending, the degree of deformation of the layer of glue 4 at this location is also greatest at the moment of bending. After the display module is restored to the unfolded state, the deformation of the display module is not restored to the maximum extent, and therefore, in the embodiment of the invention, the second hollow-out region 42 is arranged, and the second hollow-out region 42 is made to pass through the folding axis 110 of the folding region 11, so as to improve the problem of aggregation or thinning of the adhesive layer 4 at the position of the folding axis 110 of the folding region 11, and further improve the flatness of the adhesive layer 4.
For example, as shown in fig. 19, fig. 19 is another schematic cross-sectional view along FF' of fig. 17, wherein the second hollow-out region 42 may also extend from the folding region 11 to the non-folding region 12.
Exemplarily, the number of the above-mentioned glue layers 4 may be provided as multiple layers, as shown in fig. 20, fig. 20 is a further schematic cross-sectional view along DD' of fig. 2, wherein, when the glue layer 4 is provided to include the first glue layer 51 and the second glue layer 52, the distance from the first glue layer 51 to the flexible display panel is D1, the distance from the second glue layer 52 to the flexible display panel is D2, and D1 > D2, along a direction perpendicular to the flexible display panel, i.e., along the third direction z; in the embodiment of the present invention, the distance D1 from the first adhesive layer 51 to the flexible display panel is the distance from the surface of the first adhesive layer 51 far away from the flexible display panel to the flexible display panel, and the distance D2 from the second adhesive layer 52 to the flexible display panel is the distance from the surface of the second adhesive layer 52 far away from the flexible display panel to the flexible display panel. The area of the hollow area 40 is an area of an orthographic projection of the hollow area 40 on a plane where the flexible display panel is located.
It will be appreciated that the deformable object, when bent and deformed, has a neutral layer, which has the same length in the bending direction as in the unfolded state, i.e. the neutral layer has the lowest bending stress during bending. The film layer on the convex side of the neutral layer is subjected to tensile stress when bent, and its length increases compared to the unfolded state. The film on the concave side of the neutral layer is subjected to a compressive stress when bent, and its length is reduced compared to that in the expanded state. The closer the distance from the neutral layer, the smaller the compressive stress or tensile stress applied to the film layer.
Therefore, when the display module is manufactured, the flexible display panel is arranged at the neutral layer of the display module through the adjustment of the thickness and the elastic modulus of each film layer, so that the stress of the flexible display panel in the bending process along with the display module is as small as possible. In the embodiment of the present invention, the hollow areas 40 are disposed in both the first adhesive layer 51 and the second adhesive layer 52, so that after a plurality of bending operations, the flatness of the first adhesive layer 51 and the second adhesive layer 52 can be improved. Moreover, the arrangement of the hollow-out areas 40 in the first adhesive layer 51 and the second adhesive layer 52 can also relieve the stress generated in the bending process of the first adhesive layer 51 and the second adhesive layer 52. In addition, in the embodiment of the invention, by adjusting the areas of the hollow-out regions 40 in the first adhesive layer 51 and the second adhesive layer 52, the area of the hollow-out region 40 in the first adhesive layer 51 with a larger distance from the flexible display panel is larger, and the area of the hollow-out region 40 in the second adhesive layer 52 with a smaller distance from the flexible display panel is smaller, so that the bending stress applied to each adhesive layer 4 can be balanced, which is beneficial to improving the bending performance of the display module.
For example, as shown in fig. 20, the first adhesive layer 51 and the second adhesive layer 52 may be disposed on the same side of the flexible display panel 2.
When the hollowed-out regions 40 are provided in both the first adhesive layer 51 and the second adhesive layer 52, the plurality of hollowed-out regions 40 may be provided to include a portion overlapping with the folding region 11 and a portion overlapping with the non-folding region 12, and the boundary 10 between the folding region 11 and the non-folding region 12 passes through the inside of the plurality of hollowed-out regions 40 along the extending direction of the boundary 10, which is shown in fig. 20. Of course, as mentioned above, the plurality of hollow-out areas 40 may be arranged in the manner shown in fig. 9, that is, the edge 410 of the plurality of hollow-out areas 40 close to the non-folding area 12 is arranged to overlap with the boundary 10 between the folding area 11 and the non-folding area 12. Alternatively, in the manner shown in fig. 10, the edges 510 of the plurality of hollow-out regions 40 close to the folding region 11 may be arranged to overlap the boundary 10 between the folding region 11 and the non-folding region 12.
Optionally, as shown in fig. 21, fig. 21 is a schematic cross-sectional view of a display module in an expanded state according to an embodiment of the present invention, wherein a cross-sectional direction is parallel to a plane passing through the first direction x and the third direction z, in an embodiment of the present invention, the hollow regions 40 located in the first adhesive layer 51 and the second adhesive layer 52 may be set to include the first hollow region 41 and the second hollow region 42, and when a distance D1 from the first adhesive layer 51 to the flexible display panel is greater than a distance D2 from the second adhesive layer 52 to the flexible display panel, a sum of an area S11 of the first hollow region 41 located in the first adhesive layer 51 and an area S12 of the second hollow region 42 is set to be greater than a sum of an area S21 of the first hollow region 41 located in the second adhesive layer 52 and an area S22 of the second hollow region 42. The areas of the first hollow-out area 41 and the second hollow-out area 42 are the areas of their respective orthographic projections on the plane of the flexible display panel.
For example, as shown in fig. 21, the area of the first adhesive layer 51 between the first hollow area 41 and the second hollow area 42 of the first adhesive layer 51 may be set to be smaller than the area of the second adhesive layer 52 between the first hollow area 41 and the second hollow area 42 of the second adhesive layer 52. At this time, when the shapes and thicknesses of the first adhesive layer 51 and the second adhesive layer 52 are set to be the same, the interval d71 between the first hollow area 41 and the second hollow area 42 of the first adhesive layer 51 may be smaller than the interval d72 between the first hollow area 41 and the second hollow area 42 of the second adhesive layer 52, that is, the area of the first adhesive layer 51 subjected to the tensile stress is set to be as small as possible, so as to reduce the damage of the tensile stress to the first adhesive layer 51.
When the first adhesive layer 51 and the second adhesive layer 52 are disposed on different sides of the flexible display panel 2, referring to fig. 22 and 23, fig. 22 is a schematic cross-sectional view taken along DD' of fig. 2, and fig. 23 is a schematic cross-sectional view of the display module shown in fig. 22 after being bent, wherein the first adhesive layer 51 is disposed on the first side 21 of the flexible display panel, and the second adhesive layer 52 is disposed on the second side 22 of the flexible display panel. As described above, when the display module is bent, the film layer on the convex side of the neutral layer will be under tensile stress when bent, and the film layer on the concave side of the neutral layer will be under compressive stress when bent. When the display module is bent toward the direction from the first side 21 to the second side 22, as shown in fig. 23, wherein the first adhesive layer 51 is located on the convex side of the flexible display panel 2, and the second adhesive layer 52 is located on the concave side of the flexible display panel 2 when the display module is bent, the distance D1 from the first adhesive layer 51 to the flexible display panel and the distance D2 from the second adhesive layer 52 to the flexible display panel are equal, and D1 is D2; the area S1 of the hollow area 40 of the first adhesive layer 51 and the area S2 of the hollow area 40 of the second adhesive layer 52 are set to be S1 > S2. Compared with the damage of the adhesive layer caused by the compressive stress, the damage of the adhesive layer caused by the tensile stress is larger, so that in the embodiment of the invention, the area of the hollow-out area 40 in the first adhesive layer 51 bearing the tensile stress is larger by setting the area of the hollow-out area 40 in the second adhesive layer 52 bearing the compressive stress in the bending process to be smaller, the tensile stress borne by the first adhesive layer 51 in the bending process can be relieved, and the bending performance of the display module is improved.
It should be noted that, when the display module is bent in a direction from the first side 21 to the second side 22, the first side 21 of the flexible display panel may be a display surface or a non-display surface.
When the first adhesive layer 51 and the second adhesive layer 52 are disposed on different sides of the flexible display panel 2, for example, the first adhesive layer 51 is disposed on the first side 21 of the display panel, the second adhesive layer 52 is disposed on the second side 22 of the display panel, and the hollow areas 40 of the first adhesive layer 51 and the second adhesive layer 52 are both disposed to include the first hollow area 41 and the second hollow area 42, and the distance D1 from the first adhesive layer 51 to the flexible display panel is equal to the distance D2 from the second adhesive layer 52 to the flexible display panel, as shown in fig. 24, fig. 24 is a schematic cross-sectional view of another display module provided in an unfolded state according to an embodiment of the present invention, when the display module is bent toward a direction from the first side 21 to the second side 22, the area of the first adhesive layer 51 between the first hollow area 41 and the second hollow area 42 of the first adhesive layer 51 can be increased, is set to be smaller than the area of the second glue layer 52 between the first and second hollowed-out areas 41 and 42 of the second glue layer 52. In the case that the shapes and thicknesses of the first adhesive layers 51 and the second adhesive layers 52 are set to be the same, the interval d81 between the first hollow-out region 41 and the second hollow-out region 42 of the first adhesive layer 51 may be smaller than the interval d82 between the first hollow-out region 41 and the second hollow-out region 42 of the second adhesive layer 52, that is, the area of the first adhesive layer 51 subjected to the tensile stress is set to be as small as possible, so as to reduce the damage of the tensile stress to the first adhesive layer 51.
