[0035] The embodiments described in this disclosure and the configurations illustrated in the drawings are merely one or more preferred embodiments, and there may be various modified examples that can replace the embodiments and drawings of this disclosure at the time of filing of this application.

[0036] In this disclosure, the same reference numbers or symbols presented in each drawing represent parts or components that perform substantially the same function.

[0037] The terminology used in this disclosure is for the purpose of describing embodiments and is not intended to limit and / or restrict the disclosed invention. The singular expression includes the plural expression unless the context clearly indicates otherwise.

[0038] While terms including ordinal numbers, such as “first,” “second,” etc., used herein may be used to describe various components, the components are not limited by the terms, and the terms are used only to distinguish one component from another. For example, without departing from the scope of the present disclosure, the first component may be referred to as the second component, and similarly, the second component may also be referred to as the first component. The term “and / or” includes any combination of a plurality of related listed items or any one of a plurality of related listed items.

[0039] The terms “leading end,” “rear end,” “upper end,” “lower end,” “front end,” “rear end,” “top surface,” “bottom surface,” “upper end,” “lower end,” “one end,” “the other end,” “left side,” and “right side” used in this disclosure are defined based on the drawings, and the shape and position of each component are not limited by these terms.

[0040] When a component or layer is described as being "on top of," "beneath," or "coupled to" another component or layer, it can be directly present or coupled to the other component or layer, and there may be intermediate components or layers present. Conversely, when a component or layer is described as being "directly on top of," "directly beneath," or "directly coupled to" another component or layer, there are no intermediate components or layers present.

[0041] As used herein, when a component or layer is referred to as “covering” or “surrounding” another component or layer, the component or layer may cover at least a portion of the other component or layer, where that portion may include a portion of the other component or may include all of the other component.

[0042] Throughout this disclosure, references to "one embodiment," "an embodiment," "an exemplary embodiment," or similar language may indicate that a feature, structure, or characteristic described in connection with the indicated embodiment is included in at least one embodiment of the present disclosure. Thus, throughout this disclosure, references to "in one embodiment," "in an embodiment," "in an exemplary embodiment," and similar language may, but do not necessarily, all refer to the same language. The embodiments described herein are exemplary embodiments, and the present disclosure is not limited thereto and may be embodied in various other forms.

[0043] The specific order or hierarchy of blocks within the process / flowchart in this disclosure is an example of an exemplary approach. Depending on design preference, the specific order or hierarchy of blocks within the process / flowchart may be rearranged. Furthermore, some blocks may be combined or omitted. The appended claims present elements of various blocks in an exemplary order and are not limited to the specific order or hierarchy presented.

[0044] Meanwhile, the supporting reinforcement member (130) as the name of the configuration used below can play a role in adjusting the position, spacing, etc. between the perforated panel (110) and the mounting module (120) among the components constituting the display device (100).

[0045] In this disclosure, the structure that plays this role is described as a support reinforcement part (130), but it is obvious that it can be referred to by various names such as a support part, a space adjustment part, a space adjustment part, and a separation state adjustment part.

[0046] As described below, the perforated panel (110) and the mounting module (120) each have different flatness and bending states (hereinafter referred to as “abnormal states”). Therefore, the bonding state between them deviates from a uniform bonding state.

[0047] The aforementioned support reinforcement (130) can play a role in responding to such problematic phenomena. More specifically, at least one of the first structure (1111) and the second structure (1112) of the perforated panel (110) may have a biased indentation or protrusion state due to the above-described abnormal condition.

[0048] Due to this, each of the plurality of LEDs (1221) positioned in at least a portion of the first aperture (H1) of the perforated panel (110) may have a difference in visibility between them. The supporting reinforcement member (130) may play a role in resolving the difference in visibility between the LEDs (1221) and ensuring uniform visibility between them.

[0049] In addition, the mounting module (120) may be provided with a plurality of configurations, such as a substrate (122) and a base panel (121). In particular, the support reinforcement member (130) may be configured to resolve the difference in visibility by securing a distance between the perforated panel (110), the base panel (121), and the substrate (122). This resolution of the difference in visibility for the plurality of LEDs (1221) may be achieved for at least one of the emitting state and the non-emitting state of the plurality of LEDs (1221).

[0050] Ultimately, even if different flatness, warping, or other deformations of the mounting module (120), substrate (122), base panel (121), etc. occur at the time of their respective manufacturing or after their manufacturing, the separation state between the assembled components due to the above-described abnormal state can be adjusted to a preset range at the time of their connection.

[0051] Hereinafter, a display device according to one or more embodiments will be described with reference to the attached drawings. FIG. 1 is a perspective view illustrating a combined state of a display device (100) according to one or more embodiments of the present disclosure.

[0052] Referring to FIGS. 1 to 3, a display device (100) may include a through-hole panel (110), a mounting module (120), and a supporting reinforcement member (130). The through-hole panel (110) of the display device (100) may include a plurality of first through-holes (H1) and a body (111) in which separate through-holes for assembly with other components are formed. The body (111) of the through-hole panel (110) may be provided in a panel type such as a polygon or a circle. However, the present disclosure is not limited thereto, and the body (111) may be included in other shapes.

[0053] Here, the body (111) may include a first structure (1111), a second structure (1112), etc. The plurality of first openings (H1) may be areas that accommodate a plurality of LEDs (1221) arranged in the mounting module (120), and the first structure (1111) and the second structure (1112) may correspond to structures arranged in the horizontal and vertical directions to be adjacent to the plurality of LEDs (12221).

[0054] These first and second structures (1111, 1112) may be formed as separate structures, but are not necessarily limited thereto. For example, they may be formed as an integral structure surrounding a plurality of first openings (H1).

[0055] The mounting module (120) of the display device (100) may include a substrate (122) and a base panel (121). The base panel (121) is configured to be assembled with a perforated panel (110) while supporting the substrate (122).

[0056] The substrate (122) of the mounting module (120) can have multiple LEDs (1221) mounted on it. In addition, not only the multiple LEDs (1221) but also the supporting reinforcement member (130) can be arranged together on the upper surface of the substrate (122). The mounting module (120) can be assembled so as to face the perforated panel (110) with the multiple LEDs (1221) and the supporting reinforcement member (130) arranged thereon.

[0057] By this assembly, one side of the support reinforcing member (130) of the display device (100) can be in contact with the perforated panel (110), and the other side can be in contact with the substrate (122) of the perforated panel mounting module (120).

[0058] For example, when a perforated panel (110) and a mounting module (120) are assembled in a vertical direction, one side of the supporting reinforcement member (130) may be the upper surface, and the other side may be the lower surface. This supporting reinforcement member (130) may play a structural role in adjusting the opposing distance between the perforated panel (110) and the mounting module (120).

[0059] FIG. 2 is an exploded perspective view illustrating an exploded state of a display device according to one or more embodiments of the present disclosure. FIG. 3 is a cross-sectional view schematically illustrating a cross-section of a display device (100) according to one or more embodiments of the present disclosure.

[0060] Referring to FIGS. 2 and 3, a plurality of LEDs (1221) can be mounted on the substrate (122) of the mounting module (120). The base panel (121) of the mounting module (120) can serve as a structural element for accommodating and fixing the substrate (122) therein via the perforated panel (110).

[0061] Here, the substrate (122) may basically include a rigid type substrate (122). In some cases, the substrate (122) may also include a flexible type substrate (122). On the body (111) of the perforated panel (110), the first structure (1111) and the second structure (1112) may be positioned in an intersecting direction with respect to each other.

[0062] In addition, holes are formed on the body (111) for the LEDs (1221), and at least some of these holes may include a plurality of first holes (H1) corresponding to a plurality of LEDs (1221). The supporting reinforcement member (130) may be positioned between the substrate (122) of the mounting module (120) and the perforated panel (110). The supporting reinforcement member (130) may correct the distance between the substrate (122) and the perforated panel (110) to become a preset correction distance.

[0063] Meanwhile, assuming that there is no such supporting reinforcement as in a conventional display device, a shadow zone (SZ) may be formed on the LED (1221) due to a positional difference (e.g., height difference or similar) between the target object, which is one of the first structure (1111) and the second structure (1112), and the plurality of LEDs (1221). (See FIG. 34) For example, when the display device is used as an outdoor display device used outdoors, the deviation of the shadow zone may become larger depending on the direction of sunlight.

[0064] In various embodiments of the present disclosure, the support reinforcement member (130) can be used to adjust the distance between the perforated panel (110) and the mounting module (120) by a preset compensation distance. In this manner, the formation range of the shaded area (SZ) where shade is cast on a plurality of LEDs (1221) can be adjusted to be uniform.

[0065] As a result, according to various embodiments of the present disclosure, the visibility of a plurality of LEDs (1221) of a display device (100) can be uniformly secured. The support reinforcing members (130) can be provided on the substrate (122) with the same or different specifications so that the formation range of the shaded area (SZ) between the plurality of LEDs (1221) becomes uniform. (See FIG. 34) Here, the specifications can be the height value, area, etc. of the support reinforcing members (130).

[0066] The supporting reinforcement member (130) may have various height values ​​so that the distance between the substrate (122) and the perforated panel (110) can be adjusted. In the process of manufacturing an actual display device, when the perforated panel (110) is manufactured by a method such as injection molding, there are cases where warping occurs or the panel is manufactured in an uneven and uneven state. However, the present disclosure is not limited in this regard. For example, other defects, such as height differences, may occur in the display during the manufacturing process due to other factors. As another example, a defect may occur in the display after the manufacturing process is completed.

[0067] This defective state of the perforated panel (110) is hereinafter referred to as the first abnormal state. In addition, the substrate (122) or base panel (121) of the mounting module (120) may also warp or become uneven during the manufacturing process.

[0068] Here, these defective states of the substrate (122) and base panel (121) are respectively described as the second abnormal state and the third abnormal state below. In the first to third abnormal states, the bending state, uneven state, location, etc. may all be different.

[0069] Accordingly, when the perforated panel (110) and the mounting module (120) are assembled, they may be close to or in contact with each other at least in some locations where there is warping or unevenness. That is, depending on the warping or unevenness, the distance between the perforated panel (110) and the mounting module (120) may not be uniform within the entire area.

[0070] FIG. 4 is a cross-sectional view schematically illustrating a cross-section of a display device according to one or more embodiments of the present disclosure. FIG. 5 is a cross-sectional view schematically illustrating a cross-section of a display device according to one or more embodiments of the present disclosure.

[0071] In Fig. 4, although the perforated panel (110) and the mounting module (120) are assembled with a certain distance between them, contact is made in some areas and separation is made in other areas due to at least one of the first to third abnormal states. That is, this shows a case where the first opposing area (110a) of the perforated panel (110) and the second opposing area (120a) of the substrate (122) opposing the first opposing area (110a) are positioned close to each other.

[0072] Figure 5 illustrates a case in which a support reinforcement member (130) is added according to one embodiment of the present disclosure. The support reinforcement member (130) serves to appropriately space the perforated panel (110) and the mounting module (120) in one area on the mounting module (120). Accordingly, the separation distance (LT) can be maintained evenly.

[0073] As a result, the perforated panel (110) can change from an abnormal state such as FIG. 4 to a corrected state such as FIG. 5. In the present disclosure, the corrected state may include a state in which a distance between the opposing surface of the perforated panel (110) facing the substrate (122) or the base panel (121) and the base panel (121) is uniformly formed within a preset range.

[0074] FIG. 6 is a cross-sectional view schematically illustrating a cross-section of a display device according to one or more embodiments of the present disclosure. FIG. 7 is a cross-sectional view schematically illustrating a cross-section of a display device according to one or more embodiments of the present disclosure.

[0075] Referring to FIG. 6, it can be seen that the base panel (121) within the mounting module (120) is spaced apart from the perforated panel (110) to a uniform degree, but an area of ​​the substrate (122) is close to the perforated panel (110). In this case, the distance between the substrate (122) and the base panel (121) may be further apart in the area (120a) close to the perforated panel (110).

[0076] Referring to Fig. 7, the supporting reinforcement member (130) serves to space the perforated panel (110) apart by a certain distance from the substrate (122), which is one of the mounting modules (120) subdivided into multiple components. Accordingly, distance adjustment can also be performed between the substrate (122) and the base panel (121). In this manner, the supporting reinforcement member (130) can correct an abnormal state.

[0077] FIG. 8 is a cross-sectional view schematically illustrating a cross-section of a display device (100) according to one or more embodiments of the present disclosure. FIG. 9 is a cross-sectional view schematically illustrating a cross-section of a display device according to one or more embodiments of the present disclosure.

[0078] Referring to Fig. 8, a state in which a portion of the substrate (122) of the mounting module (120) in which a recessed area (122d) is formed is shown as being close to the perforated panel (110). Referring to Fig. 9, the supporting reinforcement member (130) can support the perforated panel (110) upward from the recessed area (122d). Accordingly, the distance between the substrate (122) and the base panel (121) and between the perforated panel (110) and the substrate (122) can be uniformly adjusted.

[0079] FIG. 10 is a plan view illustrating a perforated panel of a display device according to one or more embodiments of the present disclosure. FIG. 11 is a plan view illustrating a state in which an LED is positioned on a perforated panel of a display device according to one or more embodiments of the present disclosure.

[0080] Although FIGS. 10 and 11 illustrate a case where each aperture is rectangular, the present disclosure is not limited to such a case. For example, the shape and size of the aperture may be varied. Referring to FIGS. 10 and 11, the aperture-type panel (110) may be provided with a plurality of apertures (H1) in a matrix form.

[0081] For convenience of explanation, the hole through which the LED (1221) in the perforated panel (110) enters is referred to as the first hole (H1) hereinafter. A plurality of LEDs (1221) may be provided on the substrate (122) so that at least a portion thereof corresponds to the first hole (H1). Accordingly, these LEDs (1221) may pass through the first hole (H1) of the perforated panel (110).

[0082] In addition, the perforated panel (110) can be mounted on the base panel (121) in a press-fixing manner so as to cover the substrate (122). The supporting reinforcement member (130) is positioned on the substrate (122) and supports the body (111) of the perforated panel (110) in response to the press-fixing, thereby bringing it into a corrected state.

[0083] Since at least one of the first structure (1111) and the second structure (1112) of the perforated panel (110) has a biased protrusion state due to the above-described abnormal state, each of the LEDs (1221) positioned on the first perforation (H1) of the perforated panel (110) and exposed to the outside may be directly or indirectly covered.

[0084] Here, the support reinforcing member (130) of the display device (100) is configured to compensate for the degree to which each LED (1221) positioned in the first hole (H1) of the perforated panel (110) is directly or indirectly blocked by an object.

[0085] FIG. 12 is a partially enlarged view of a perforated panel of a display device according to one or more embodiments of the present disclosure. FIG. 13 is a view illustrating a bottom surface of a perforated panel of a display device according to one or more embodiments of the present disclosure.

[0086] Referring to FIGS. 12 and 13, the second structure (1112) may be provided with a first compartment (1112a), a second compartment (1112b), a third compartment (1112c), etc. Here, the first compartment (1112a), the second compartment (1112b), the third compartment (1112c), etc. may be formed to be tapered toward the outside.

[0087] Here, the perforated panel (110) may be provided with one or more insertion pins (111T) on the lower surface facing the substrate (122). The perforated panel (110) may be assembled to at least one of the substrate (122) and the base panel (121) by inserting the insertion pins (111T), etc.

[0088] FIG. 14 is a plan view illustrating a substrate of a display device according to one or more embodiments of the present disclosure. FIG. 15 is a partially enlarged view of a substrate of a display device according to one or more embodiments of the present disclosure.

[0089] FIG. 16 is a perspective view illustrating a bottom surface of a substrate of a display device according to one or more embodiments of the present disclosure. Referring to FIGS. 14, 15, and 16, a plurality of LEDs (1221) may be provided on the substrate (122) at preset intervals.

[0090] For example, the support reinforcement member (130) may be provided between these LEDs (1221). At least one of the plurality of support reinforcement members (130) may be arranged in parallel on one side of the plurality of LEDs (1221) on the substrate (122) of the mounting module (120).

[0091] When the mounting module (120) and the perforated panel (110) are mutually assembled so that a plurality of LEDs (1221) are arranged within a plurality of first perforations (H1), a plurality of support reinforcing members (130) can contact the bottom surface of the perforated panel (110) on one side of the plurality of LEDs (1221), thereby spacing the substrate (122) and the perforated panel (110) apart by a preset distance.

[0092] In particular, the supporting reinforcement member (130) may be provided in one or more portions where the distance between the perforated panel (110) and the substrate (122) needs to be adjusted. A plurality of perforations may be formed on the substrate (122). For convenience of explanation, some of the plurality of perforations formed on the substrate (122) are referred to as second perforations (H2).

[0093] The second aperture (H2) of the substrate (122) can be utilized for module assembly together with a separate aperture (not shown) of the perforated panel (110). The substrate (122) can be provided with a connector (1222) for electrical connection.

In S120, a perforated panel (110) and a mounting module (120) may be assembled.

[0098] Here, the mounting module (120) may include a plurality of LEDs (1221) and a plurality of support reinforcing members (130) arranged on a substrate (122). The substrate (122) may be assembled with the perforated panel (110) so that the plurality of LEDs (1221) enter into a plurality of first perforations (H1) formed in the perforated panel (110). Through this assembly, the substrate (122) and the perforated panel (110) may be spaced apart from each other by a preset distance by making contact with the bottom surface of the perforated panel (110).

[0099] FIGS. 21 to 25 are schematic cross-sectional views of a display device according to one or more embodiments of the present disclosure. Referring to FIGS. 14, 15, 21, and 22, a substrate (122) may have a coating layer (C) formed at a location on the surface that includes a plurality of LEDs (1221) and a supporting reinforcement member (130).

[0100] Here, the coating layer (C) can be formed while the supporting reinforcement member (130) is installed on the substrate (122). The perforated panel (110) can have a first perforation (H1) formed therein. The substrate (122) can have a second perforation (H2) formed therein corresponding to the first perforation (H1). (See FIGS. 14 and 15)

[0101] The base panel (121) may be formed with a third aperture (H3) corresponding to the second aperture (H2). The aperture-type panel (110), the substrate (122), and the base panel (121) may be fixed through a fixing member (BT).

[0102] The support reinforcement member (130) can be adjusted in a distance corresponding to the installation of the fixing member (BT). The first structure (1111) can be positioned to protrude upward from the upper surface of the perforated panel (110) and to partition a plurality of LEDs (1221).

[0103] More specifically, the through-hole panel (110), the substrate (122), and the base panel (121) can be sequentially fixed to each other in a pressurized manner through a fixing member (BT).

[0104] Here, the fixed member (BT) may include a sub-material such as a forced-fit method or a screw-turn method. The supporting reinforcement member (130) may be installed on the substrate (122) using a SMD (Surface Mount Device) method, etc. The supporting reinforcement member (130) may be provided in a shape in which one side and the other side correspond to each other in a uniform form.

[0105] The coating layer (C) on the fixing member (BT) of the display device (100) may be formed after the fixing member (BT) is fastened to the corresponding position, or after the coating layer (C) is formed, the fixing member (BT) is installed and the coating layer (C) is formed.

[0106] Referring to FIGS. 23, 24, and 25, the display device (100) may be installed with the LED (1221) first installed on the substrate (122) and then the support reinforcement member (130). Conversely, the LED (1221) may be installed with the support reinforcement member (130) after the support reinforcement member (130) is installed on the substrate (122). It is also possible to install the LED (1221) and the support reinforcement member (130) together on the substrate (122).

[0107] Referring to Fig. 26, the supporting reinforcement (130) is basically square or rectangular and supports the body (111) of the perforated panel (110), thereby being able to support the first structure (1111) on the body (111).

[0108] Referring to Fig. 27, as a modified example of the supporting reinforcement member (130), it may be provided in a frustum type including a reduced portion (1301) that is in contact with the substrate (122) on one side and an expanded portion (1302) that is in contact with the body (111) on the other side. That is, it may correspond to a state in which the side surface is tapered so that the cross-sectional area of ​​the portion in contact with the substrate (122) is narrower than the cross-sectional area of ​​the portion in contact with the perforated panel (110). The supporting reinforcement member (130) may include a columnar shape having a circular or polygonal cross-section.

[0109] In this case, the supporting reinforcement (130) can support the perforated panel (110) by making contact with a wider area on the body (111) of the perforated panel (110). In addition, the distance between the substrate (122) and the perforated panel (110) as well as the contact area with the body (111) of the perforated panel (110) can be relatively expanded.

[0110] Accordingly, the degree of upward rounding of the perforated panel (110) can be relatively more gently controlled. Here, one side of the supporting reinforcement (130) can contact the substrate (122) with a relatively reduced area compared to the other side, so that a concentrated pressing force can be applied to the substrate (122).

[0111] FIG. 28 is a drawing partially illustrating a substrate of a display device according to one or more embodiments of the present disclosure. Referring to FIG. 28, as another modified example of the support reinforcement member (130), the support reinforcement member (130) may be provided in a frustum type including an expansion member (1301) that is in contact with the substrate (122) on one side and a reduction member (1302) that is in contact with the body (111) on the other side.

[0112] Here, the support reinforcing member (130) of the display device (100) can support the perforated panel (110) by making contact with the body (111) of the perforated panel (110) over a narrower area.

[0113] In addition, the distance between the substrate (122) and the perforated panel (110) as well as the contact area of ​​the perforated panel (110) with the body (111) can be relatively reduced. In other words, the degree to which the perforated panel (110) is rounded upward can be adjusted to be relatively more inclined.

[0114] In addition, one side of the support reinforcement (130) may contact the substrate (122) with a relatively expanded area compared to the other side, so that a distributed pressing force may be applied to the substrate (122).

[0115] This enables concentrated pressure to be applied to the body (111) of the perforated panel (110) while suppressing the external force load on the substrate (122). In particular, when the thickness of the substrate (122) corresponds to a thin standard, it is possible to prevent the substrate (122) from being damaged.

[0116] In addition, when the supporting reinforcement (130) comes into contact with the circuit pattern formed on the substrate (122), it is possible to prevent negative effects such as pressure or damage from being applied to the circuit pattern.

[0117] FIG. 29 is a diagram illustrating a layout of a display device according to one or more embodiments of the present disclosure. Referring to FIG. 29, a plurality of display devices (100) may be provided.

[0118] The display device (100) may be provided such that one display device (100) and another display device (100) corresponding to the display device (100) are symmetrically adjacent to each other.

[0119] Referring to FIG. 30, the substrate (122) of the display device (100) may include an inner region (122a) and outer regions (122b) on the upper, lower, left, and right sides where the coating layer (C) corresponding to the outer region (122b) of the inner region (122a) is not applied.

[0120] Each edge portion of the outer region (122b) of the substrate (122) may have a region of a preset width. Here, the edge portion may include a rectangular range in which the width and length are each within a range of 3.5 mm to 4.5 mm, etc. Here, the thickness value of the coating layer (C) may include a value within a range of about 120 μm to about 180 μm, etc.

[0121] FIG. 31 is a schematic diagram illustrating a base panel, a substrate, and a positioning state of a display device according to one or more embodiments of the present disclosure. Referring to FIG. 31, after a coating layer (C) is applied to the base panel (121), the substrate (122) can be installed on the base panel (121) to which the coating layer (C) is applied.

[0122] Through this, waterproofing treatment can be achieved between the base panel (121) and the substrate (122). The coating layer (C) can be formed by spraying on the bottom space on the substrate (122) facing the base panel (121) and the side space on the substrate (122) facing the base panel (121).

[0123] FIGS. 32 to 34 are drawings illustrating a state in which a base panel, a substrate, and a perforated panel are joined in a state in which a supporting reinforcement member is absent. Referring to FIGS. 12 and 32, a second structure (1112) may be positioned to protrude upward from the upper surface of the perforated panel (110) and to define a plurality of LEDs (1221) in an intersecting direction intersecting with the first structure (1111). The first structure (1111) and the second structure (1112) may be provided to surround the plurality of LEDs (1221).

[0124] Fig. 33 is a drawing illustrating the state of the connection between the base panel and the substrate. Referring to Figs. 32 and 33, among the plurality of LEDs (1221), the first LED (1221a) and the second LED (1221b) that are adjacent to each other may be positioned in different states.

[0125] For example, the first LED (1221a) and the second LED (1221b) may have an abnormal state between the perforated panel (110), the substrate (122), and the base panel (121) and the bonding state between them, so that the first LED (1221a) may have a first exposure level (A) and the second LED (1221b) may have a second exposure level (B).

[0126] FIG. 35 is a diagram illustrating different states of visibility of a display device according to one or more embodiments of the present disclosure. Referring to FIGS. 34 and 35, the first LED (1221a) has a first exposure degree (A), and the second LED (1221b) has a second exposure degree (B), and the first LED (1221a) and the second LED (1221b) have different degrees of formation of a shaded area (SZ) formed by external light (SL) through the second structure (1112).

[0127] Accordingly, a phenomenon occurs in which the visibility of each display device (100) becomes different. Of course, even if there is no height difference between the plurality of LEDs (1221), the degree of formation of the shaded area (SZ) in the plurality of LEDs (1221) may vary depending on an abnormal state of at least one of the base panel (121), the substrate (122), and the perforated panel (110).

[0128] FIG. 36 is a diagram illustrating a state in which the visibility of a display device according to one or more embodiments of the present disclosure is uniform. Referring to FIG. 36, it can be confirmed that the difference in visibility on the display device (100) due to the above-described abnormal state is resolved by applying the support reinforcement member (130) of the display device (100).

While the present disclosure has been illustrated and described with reference to various embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
