Display device

Abstract

The invention relates to a display device. Disclosed is a display device including a lower substrate having a display area, first non-display areas located on both sides of the display area in a first direction, and a second non-display area located on one side of the display area in a second direction different from the first direction. A plurality of plate patterns are disposed in the display area, the first non-display area, and the second non-display area, and a plurality of line patterns are disposed between adjacent plate patterns in each of these areas. The plate pattern in the second non-display area has a different size, wherein the plate pattern closer to the display area is formed smaller than the plate pattern farther from the display area. By changing the size of the plate pattern and correspondingly arranging the line pattern, a tensile stress applied to the non-display area can be dispersed, thereby reducing the possibility of cracking and enhancing the mechanical reliability of the device.

Description

Technical Field

[0001] This disclosure relates to a display device, and more specifically, to a stretchable display device that can be stretched. Background Technology

[0002] As display devices used for computer monitors, televisions, or mobile phones, there are organic light-emitting display devices (OLEDs) that are self-emissive and liquid crystal display devices (LCDs) that require a separate light source.

[0003] Display devices have a wide range of applications, including personal digital assistants, computer monitors, and televisions, and research is underway on display devices with large display areas that are smaller and lighter.

[0004] In addition, the following display devices have recently attracted attention as next-generation display devices, which are manufactured by forming display units and wiring lines on a flexible substrate made of a flexible material such as plastic, so that they can be stretched in a specific direction and changed in various forms.

[0005] The description provided in the Background section should not be assumed to be prior art simply because it is mentioned in or associated with the description in the Background section. The Background section may include information describing one or more aspects of the subject matter art, and the description in this section does not limit this disclosure. Summary of the Invention

[0006] In the prior art, the non-display areas of a display device are susceptible to excessive stretching, and the pattern layer of the display device is prone to damage due to cracking. Therefore, this disclosure provides a display device that minimizes tensile stress.

[0007] Specifically, this disclosure addresses the limitations of conventional flexible and stretchable displays (i.e., excessive stretching in non-display areas and cracking in the patterned layer). This disclosure emphasizes that the plate pattern in the second non-display area is formed with dimensions gradually decreasing towards the display area, thereby dispersing stress during stretching and suppressing crack formation.

[0008] On the other hand, non-uniform line pattern geometry is used, where the line patterns are configured with different length ratios (e.g., varying wavy or zigzag shapes). This arrangement ensures that some lines are stretched more than others, effectively preventing excessive stretching in non-display areas and protecting the integrity of the pattern layer. Furthermore, link lines are located on the line patterns within non-display areas, enabling stable electrical signal transmission while accommodating mechanical deformation.

[0009] Arranging board and line patterns on flexible substrates provides structural configurations that contribute to flexibility and durability. Features such as variations in board size, adjustments to line pattern geometry, and the placement of connecting lines can be implemented individually or in combination to influence the distribution of mechanical stress and reduce the likelihood of cracking. Through these design approaches, display devices can achieve improved stretchability and mechanical reliability while maintaining electrical performance.

[0010] For example, various embodiments of this disclosure provide a display device that suppresses excessive stretching of non-display areas.

[0011] Various embodiments of this disclosure provide a display device for suppressing damage or cracking of the pattern layer.

[0012] The technical benefits of this disclosure are not limited to those described above, and those skilled in the art will clearly understand from the following description other benefits not mentioned above.

[0013] To achieve the aforementioned benefits, according to one aspect of this disclosure, a display device includes: a lower substrate comprising a display area, a first non-display area located on both sides of the display area along a first direction, and a second non-display area located on one side of the display area along a second direction different from the first direction; a plurality of board patterns located in the display area, the first non-display area, and the second non-display area; and a plurality of line patterns located between the plurality of board patterns in the display area, the first non-display area, and the second non-display area, wherein the plurality of board patterns disposed in the second non-display area have different sizes.

[0014] To achieve the above objectives, according to one aspect of this disclosure, a display device may include: a lower substrate including a display area, a first non-display area located on both sides of the display area along a first direction, and a second non-display area located on one side of the display area along a second direction different from the first direction; a plurality of board patterns located in the display area, the first non-display area, and the second non-display area; a plurality of line patterns located between the plurality of board patterns in the display area, the first non-display area, and the second non-display area; and a plurality of connecting lines located on the plurality of line patterns in the second non-display area.

[0015] Further details of exemplary embodiments are included in the detailed description and accompanying drawings.

[0016] In a display device according to an exemplary embodiment of the present disclosure, in a non-display area disposed on one side of the display area, the size (or area) of the plate pattern bonded to the flexible film gradually decreases from the flexible film toward the display area. Therefore, when the display device is stretched, the tensile stress of the line patterns connecting adjacent plate patterns in the non-display area and the linking lines disposed on the line patterns can be effectively dispersed. Thus, damage or cracking of the pattern layer included in the display device can be suppressed.

[0017] Furthermore, in the case of the display device according to an exemplary embodiment of this disclosure, the length ratio of the line patterns connected to the plate pattern bonded to the flexible film in the non-display area can have different values ​​in each line pattern. Therefore, when the display device is stretched, excessive stretching of the non-display area can be suppressed, and damage or cracking of the pattern layer included in the display device can be suppressed.

[0018] The effects of this disclosure are not limited to the examples above, and many more different effects are included in this specification. Attached Figure Description

[0033] Implementations of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. The progression of the described processing steps and / or operations is illustrative; however, the order of the steps and / or operations is not limited to the order described herein and can be varied as is known in the art, except for steps and / or operations that must occur in a specific order. The names of the various elements used in the following description may have been chosen merely for ease of writing and may therefore differ from the names used in actual products.

[0034] The advantages and features of this disclosure, as well as methods for achieving these advantages and features, will become clear from the exemplary embodiments described in detail below with reference to the accompanying drawings. However, this disclosure is not limited to the exemplary embodiments disclosed herein, but will be implemented in various forms. Exemplary embodiments are provided by way of example only to enable those skilled in the art to fully understand the disclosure and scope of this disclosure.

[0035] The shapes, sizes, dimensions (e.g., length, width, height, thickness, radius, diameter, area, etc.), ratios, angles, quantities, etc., shown in the accompanying drawings to describe exemplary embodiments of this disclosure are merely examples, and this disclosure is not limited thereto. Throughout the specification, the same reference numerals generally denote the same elements. Furthermore, in the following description of this disclosure, detailed descriptions of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of this disclosure. Terms such as “comprising,” “having,” “including,” “containing,” “constituting,” “made of,” “formed from,” “composed of”, and “consisting of” as used herein are generally intended to allow for the addition of other components, unless these terms are used in conjunction with the term “only.” Unless otherwise expressly stated, any reference to the singular may include the plural.

[0036] The dimensions (including size and thickness) of the various components shown in the accompanying drawings are for ease of description, and this disclosure is not limited to the size and thickness of the components shown. However, it should be noted that the relative dimensions (including relative size, position and thickness) of the components shown in the various drawings submitted herein are part of this disclosure.

[0037] Even if not explicitly stated, the component is to be interpreted as including the normal tolerance range.

[0038] When described as a “connection” or “linkage”, unless the terms “direct” or “immediately” are used, the connection or link may include an indirect connection or link through one or more other components located between the two elements.

[0039] When using terms such as “on top of,” “above,” “above,” “below,” “below,” “next to,” “under,” “near,” “close to,” “adjacent to,” “side of,” “near,” to describe the positional relationship between two parts, one or more parts may be located between the two parts, unless the term is used with the terms “immediately adjacent” or “directly.”

[0040] For ease of description, spatial relative terms such as “below,” “under,” “below,” “lower,” “above,” and “upper” may be used herein to describe the relationship between one element or feature and another element or feature as illustrated in the figures. It should be understood that, in addition to the orientations shown in the figures, spatial relative terms may also include different orientations of elements in use or operation. For example, if the elements in the figures are inverted, an element described as being “below” or “below” other elements or features would be oriented as being “above” other elements or features. Thus, the exemplary term “below” can include both lower and upper orientations. Similarly, the exemplary terms “above” or “above” can include both upper and lower orientations.

[0041] The word “exemplary” is used to indicate that something is presented as an example or illustration. “Aspect” refers to an exemplary aspect. “Implementation,” “example,” “aspect,” etc., should not be construed as being more preferred or advantageous than other implementations. Unless otherwise stated, implementation, example, exemplary implementation, aspect, etc., may refer to one or more implementations, one or more examples, one or more exemplary implementations, one or more aspects, etc. Furthermore, the word “may” encompasses all meanings of the word “able to.”

[0042] When a component or layer is placed "on" another component or layer, the other component or layer can be placed directly on the other component or layer or inserted between the two components or layers.

[0043] When describing temporal relationships, for example, when using terms such as "after," "following," "next," and "before" to describe the temporal relationship of events, there may also be cases where events are not consecutive, unless "immediately after" or "directly" is used.

[0044] Although the terms "first," "second," etc., are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from others. Therefore, the first component mentioned below can be a second component in the technical concept of this disclosure.

[0045] The term "at least one / one" should be understood to include all possible combinations of suggestions from one or more related projects. For example, "at least one / one of the first, second, or third projects" could mean each of the first, second, or third projects, and could also mean all possible combinations of two or more suggestions from the first, second, and third projects.

[0046] As used herein, the term "connection" is intended to have the broadest possible meaning. Specifically, the phrase "A connected to B" encompasses both a direct connection (where no intermediate parts or elements exist) and an indirect connection (where one or more intermediate parts or elements exist between A and B). In other words, "A connected to B" includes both a direct physical or electrical connection and an indirect connection via one or more intermediate parts. Unless otherwise explicitly stated, these terms do not require direct physical or electrical contact. The terms "connection" and "contact" should be interpreted in the same manner.

[0047] As used herein, the term "device" can refer to a display device that includes a display panel and a driver for driving the display panel. Examples of display devices may include light-emitting elements, etc. Furthermore, examples of devices may include laptops, televisions, computer monitors, automotive devices, wearable devices and automotive equipment devices, as well as assemblies of electronic devices (or equipment) or assemblies (or devices) that include light-emitting elements, etc., as complete products or end products, such as mobile electronic devices like smartphones or tablets, but embodiments of this disclosure are not limited thereto.

[0048] Features of the various embodiments of this disclosure may be combined or integrated with each other in part or in whole, and may be technically interlocked and operated in various ways, and these embodiments may be implemented independently or in association with each other.

[0049] Unless otherwise specified, all terms (including technical terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It should also be understood that terms (e.g., terms as defined in common dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0050] In this disclosure, for ease of description, the source electrode and drain electrode are distinguished from each other. However, the source electrode and drain electrode are used interchangeably. A source electrode can be a drain electrode, and a drain electrode can be a source electrode. Furthermore, a source electrode in any aspect of this disclosure can be a drain electrode in another aspect of this disclosure, and a drain electrode in any aspect of this disclosure can be a source electrode in another aspect of this disclosure.

[0051] In the specification, when adding reference numerals to the elements in each drawing, care should be taken to use the same reference numerals that have been used to represent the same elements in other drawings whenever possible. Furthermore, for ease of description, the scale of the components shown in the drawings may differ from the actual scale. That is, the scale of the components shown in the drawings should not be interpreted as the same as the scale shown in the drawings.

[0052] This disclosure will be described in detail below with reference to the accompanying drawings.

[0053] The display device according to the exemplary embodiments of this disclosure is a display device capable of displaying images even in a bent or extended state, and is also referred to as a stretchable display device, a flexible display device, and an extendable display device. Compared with general display devices of the related art, this display device not only has high flexibility but also stretchability. Therefore, the user can bend or extend the display device, and the shape of the display device can be freely changed according to the user's manipulation. For example, when the user pulls the display device by holding its end, the display device can extend in the direction of the user's pull. Alternatively, when the user places the display device on an uneven outer surface, the display device can be configured to bend according to the shape of the outer surface of the wall. Furthermore, when the force applied by the user is removed, the display device can return to its original shape.

[0054] Figure 1 This is a schematic plan view of a display device according to an exemplary embodiment of the present disclosure.

[0055] At the same time, for ease of description, in Figure 1 In the various configurations of the display device 100, only the lower substrate 111, the flexible film 130, and the printed circuit board PCB are shown.

[0056] Reference Figure 1 The lower substrate 111 can support multiple components of the display device 100. The lower substrate 111 may include a display area AA for displaying an image and a non-display area NA other than the display area AA. For example, the non-display area NA surrounds the display area AA.

[0057] Multiple pixels, each including display elements and circuit elements, are disposed on the display area AA, and a gating driver and power supply for driving the multiple pixels disposed in the display area AA can be disposed on the non-display area NA. The non-display area NA is an area where no image is displayed, and can be defined in the edge portion of the lower substrate 111 to surround part or all of the display area AA. The non-display area NA can be an area adjacent to the display area AA. Furthermore, the non-display area NA can be an area disposed adjacent to the display area AA and configured to surround the display area AA. However, this disclosure is not limited thereto.

[0058] In one exemplary embodiment, the non-display area NA may include a first non-display area NA1, a second non-display area NA2, and a third non-display area NA3.

[0059] The first non-display area NA1 can be located on the left, right, and bottom sides of the display area AA. For example, the first non-display area NA1 can be set on both sides (e.g., the left and right sides) of the display area AA along the first direction X, and on one side (e.g., the bottom side) in the opposite direction along the second direction Y. A gating driver and a power supply can be set on the first non-display area NA1.

[0060] The second non-display area NA2 may be a region corresponding to the portion of the non-display area NA located above the display area AA. For example, the second non-display area NA2 may be located on one side (e.g., the upper side) of the display area AA along the second direction Y. In the second non-display area NA2, multiple pads connected to the flexible film 130 and multiple link lines transmitting signals from the multiple pads to the display area AA may be provided. The second non-display area NA2 is a region located between the multiple pads starting from the upper side of the display area AA, and may have a shape that widens from the multiple pads toward the display area AA. For example, the second non-display area NA2 may extend radially relative to the multiple pads.

[0061] The third non-display area NA3 can be the remaining area of ​​the non-display area NA above the display area AA, excluding the second non-display area NA2. For example, the third non-display area NA3 can be located on both sides of the second non-display area NA2. For example, the third non-display area NA3 can be located on both sides (e.g., the left and right sides) of the second non-display area NA2 along the first direction X.

[0062] The boundary area between the display area AA and the non-display area NA can be curved, allowing the non-display area NA to be located below the display area. In this case, when a user views the display device from the front, little or no non-display area NA may be visible to the user.

[0063] The flexible film 130 is a film in which various components are disposed on a flexible base film 131, and can provide signals to multiple pixels PX of the display area AA. The flexible film 130 can be bonded to multiple pads disposed in a second non-display area NA2, and provides various signals to each of the multiple pixels in the display area AA through the pads and multiple interconnecting lines. The flexible film 130 includes a base film 131 and a driver IC 132. Furthermore, various components can be disposed on the flexible film 130.

[0064] The base film 131 can support the driving IC 132 of the flexible film 130. The base film 131 can be formed of an insulating material, and for example, it can be formed of an insulating material with flexibility. For example, the base film can include a flexible polymer film. For example, the flexible polymer film can be made of any of polyimide (PI), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polycarbonate (PC), polyethersulfone (PES), polyarylate (PAR), polysulfone (PSF), cyclic olefin copolymer (COC), triacetyl cellulose (TAC), polyvinyl alcohol (PVA), and polystyrene (PS). However, this disclosure is not limited thereto.

[0065] The driver IC 132 processes data used for displaying images and drive signals used for processing images. Figure 1 Although the driver IC 132 is shown to be mounted via chip-on-film (COF) 130 technology, it is not limited thereto, and the driver IC 132 can be mounted via technologies such as chip-on-glass (COG) or tape-on-carrier (TCP).

[0066] A printed circuit board (PCB) can be connected to multiple flexible films 130. Controllers, such as IC chips or circuit units, can be mounted on the PCB. Furthermore, memory or processors can also be mounted on the PCB. The PCB can generate signals for driving pixels.

[0067] In the following text, reference will be made to Figures 2 to 4 The display area AA and the first non-display area NA1 of the display device 100 will be described in more detail. (Refer to...) Figures 5 to 12 The second non-display area NA2 and the third non-display area NA3 of the display device 100 are described in more detail.

[0068] Figure 2 This is a plan view of the display area and the first non-display area of ​​a display device according to an exemplary embodiment of the present disclosure.

[0069] Reference Figure 1 and Figure 2 The display device 100 according to an exemplary embodiment of the present disclosure may include a lower substrate 111, a pattern layer 120, a plurality of pixels PX, a gating driver GD, a data driver, and a power supply PS. In one exemplary embodiment, the display device 100 may further include an upper substrate (e.g., Figure 4 (Upper substrate 112).

[0070] The lower substrate 111 supports a patterned layer 120 on which pixels (PX), gate drivers (GD), and power supplies (PS) are formed, and the upper substrate 112 is disposed on the lower substrate 111 and can cover the various components of the display device 100. In an exemplary embodiment, the lower substrate 111 and the upper substrate 112 are flexible substrates and can be made of a bendable or stretchable insulating material. For example, the lower substrate 111 and the upper substrate 112 may include a flexible polymer film. For example, the flexible polymer film can be made of any of polyimide (PI), polyethylene terephthalate (PET), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polycarbonate (PC), polyethersulfone (PES), polyarylate (PAR), polysulfone (PSF), cyclic olefin copolymer (COC), triacetyl cellulose (TAC), polyvinyl alcohol (PVA), and polystyrene (PS). However, this disclosure is not limited thereto.

[0071] The elastic modulus of the lower substrate 111 and the upper substrate 112 can range from several MPa to several hundred MPa. Furthermore, the ductile fracture rate of the lower substrate 111 and the upper substrate 112 can be 100% or higher. Here, the ductile fracture rate refers to the elongation at which the object to be stretched breaks or cracks.

[0072] Pattern layer 120 may be disposed on lower substrate 111. In an exemplary embodiment, pattern layer 120 may include a plurality of first board patterns 121P and a plurality of first line patterns 121L disposed in display area AA, and a plurality of second board patterns 122P and a plurality of second line patterns 122L disposed in first non-display area NA1. For example, the plurality of first board patterns 121P and the plurality of second board patterns 122P may be formed as separate / individual islands. The plurality of first line patterns 121L connect adjacent first board patterns 121P, and the plurality of second line patterns 122L may connect adjacent first board patterns 121P and second board patterns 122P or adjacent second board patterns 122P.

[0073] Multiple pixels PX are formed on multiple first board patterns 121P, and gating drivers GD and power supplies PS can be formed on multiple second board patterns 122P.

[0074] At the same time, despite Figure 1 The diagram shows multiple first plate patterns 121P and multiple second plate patterns 122P having quadrilateral shapes, but is not limited thereto.

[0075] The plurality of first line patterns 121L and the plurality of second line patterns 122L have a wavy shape (e.g., a sine wave shape), but are not limited thereto. For example, the plurality of first line patterns 121L and the plurality of second line patterns 122L may extend in a zigzag pattern or may be formed in various shapes (e.g., a shape that extends by connecting a plurality of rhomboid substrates at the apex, or a shape in which semi-circular or quarter-circular substrates are connected to each other).

[0076] In one exemplary embodiment, the plurality of first plate patterns 121P, the plurality of first line patterns 121L, the plurality of second plate patterns 122P, and the plurality of second line patterns 122L of the pattern layer 120 may be rigid patterns. For example, the plurality of first plate patterns 121P, the plurality of first line patterns 121L, the plurality of second plate patterns 122P, and the plurality of second line patterns 122L may be more rigid than the lower substrate 111 and the upper substrate 112. Therefore, the elastic modulus and hardness of the plurality of first plate patterns 121P, the plurality of first line patterns 121L, the plurality of second plate patterns 122P, and the plurality of second line patterns 122L may be higher than the elastic modulus and hardness of the lower substrate 111. For example, the elastic modulus of the plurality of first plate patterns 121P, the plurality of first line patterns 121L, the plurality of second plate patterns 122P, and the plurality of second line patterns 122L may be 1000 times higher than the elastic modulus of the lower substrate 111 and the upper substrate 112, but is not limited thereto.

[0077] Multiple first plate patterns 121P, multiple first line patterns 121L, multiple second plate patterns 122P, and multiple second line patterns 122L can be formed from a plastic material with lower flexibility than the lower substrate 111 and the upper substrate 112.

[0078] The gating driver GD can provide gating signals to multiple pixels PX disposed in the display area AA. The gating driver GD includes multiple stages formed on multiple second board patterns 122P, and each stage of the gating driver GD can be electrically connected to each other through multiple gating connection lines. Therefore, a gating signal output from any stage can be transmitted to another stage. Each stage can sequentially provide gating signals to multiple pixels PX connected to each stage.

[0079] The power supply PS is electrically connected to the gating driver GD and multiple pixels PX to provide driving voltage.

[0080] Figure 3 yes Figure 2 An enlarged plan view of an example of the display area of ​​a display device.

[0081] Figure 4 It shows along Figure 3 The example cross-sectional view shown is taken from line IV-IV'.

[0082] Reference Figures 1 to 3Multiple first board patterns 121P can be disposed on the display area AA of the lower substrate 111. The multiple first board patterns 121P are spaced apart from each other to be disposed on the lower substrate 111. For example, the multiple first board patterns 121P can be arranged in a matrix on the lower substrate 111, but are not limited thereto.

[0083] A pixel PX comprising multiple sub-pixels SPX can be disposed in a first plate pattern 121P. Each sub-pixel in the multiple sub-pixels SPX may include an LED 170 (or a light-emitting element) as a display element and circuit elements (e.g., at least one transistor) for driving the LED 170. However, this is merely illustrative, and in the sub-pixel SPX, the display element is not limited to LEDs and may also be changed to an organic light-emitting diode.

[0084] Multiple sub-pixels (SPX) can include, but are not limited to, red, green, and blue sub-pixels, and the colors of multiple sub-pixels (SPX) can be changed to various colors as needed.

[0085] For example, multiple sub-pixels may include red, green, and blue sub-pixels, wherein the red, green, and blue sub-pixels may be arranged in a repeating manner. Alternatively, multiple sub-pixels SP may include red, green, blue, and white sub-pixels, wherein the red, green, blue, and white sub-pixels may be arranged in a repeating manner, or the red, green, blue, and white sub-pixels may be arranged in a quad type. For example, the red, blue, and green sub-pixels may be arranged sequentially along the row direction, or the red, blue, green, and white sub-pixels may be arranged sequentially along the row direction. However, in embodiments of this disclosure, the color type, arrangement type, and arrangement order of the sub-pixels are not limited and can be configured in various forms according to light-emitting characteristics, device lifetime, and device specifications.

[0086] Furthermore, based on their light-emitting characteristics, sub-pixels can have different light-emitting areas. For example, a sub-pixel that emits light of a different color than the blue sub-pixel can have a different light-emitting area than the blue sub-pixel. For instance, red, blue, and green sub-pixels, or red, blue, white, and green sub-pixels, can each have different light-emitting areas.

[0087] Multiple sub-pixels SPX can be connected to multiple connection lines 181 and 182. For example, multiple sub-pixels SPX can be electrically connected to a first connection line 181 extending along a first direction X and a second connection line 182 extending along a second direction Y.

[0088] In the following text, reference will be made to Figure 4 The cross-sectional structure of the display device 100 in the display area AA according to an exemplary embodiment of the present disclosure is described in more detail.

[0089] Reference Figure 4 Multiple first board patterns 121P and multiple first line patterns 121L connecting adjacent first board patterns 121P can be disposed on the display area AA of the lower substrate 111.

[0090] Multiple inorganic insulating layers can be disposed on multiple first board patterns 121P. For example, the multiple inorganic insulating layers may include a buffer layer 141, a gate insulating layer 142, a first interlayer insulating layer 143, a second interlayer insulating layer 144, and a passivation layer 145, but are not limited thereto.

[0091] A buffer layer 141 is disposed on a plurality of first plate patterns 121P and may include an insulating material. For example, the buffer layer 141 may be formed by a single or multiple inorganic film. For instance, a single inorganic film may be a silicon oxide (SiOx) film or a silicon nitride (SiNx) film, while multiple inorganic films may be formed by alternately stacking one or more layers of silicon oxide (SiOx) film, one or more layers of silicon nitride (SiNx) film, and one or more layers of amorphous silicon (a-Si), but this disclosure is not limited thereto. However, depending on the structure or characteristics of the display device, the buffer layer 141 may not be included.

[0092] In one exemplary embodiment, the buffer layer 141 is formed only in the region that overlaps with the plurality of first plate patterns 121P and the plurality of second plate patterns 122P, and not in the region located between the plurality of first plate patterns 121P and the plurality of second plate patterns 122P.

[0094] First, the switching active layer 152 of the switching transistor 150 and the driving active layer 162 of the driving transistor 160 can be disposed on the buffer layer 141.

[0095] The active layers of the switching active layer 152 of the switching transistor 150 and the driving active layer 162 of the driving transistor 160 can be formed of semiconductor materials (e.g., oxide semiconductor, amorphous semiconductor or polycrystalline semiconductor), but are not limited thereto.

[0096] Oxide semiconductor materials offer excellent leakage current prevention and relatively low manufacturing costs. Oxide semiconductors can be made from metal oxides such as zinc (Zn), indium (In), gallium (Ga), tin (Sn), and titanium (Ti), or combinations of metals and their oxides such as zinc (Zn), indium (In), gallium (Ga), tin (Sn), or titanium (Ti). Specifically, oxide semiconductors can include, but are not limited to, zinc oxide (ZnO), zinc tin oxide (ZTO), zinc indium oxide (ZIO), indium oxide (InO), titanium oxide (TiO), indium gallium zinc oxide (IGZO), indium zinc tin oxide (IZTO), indium zinc oxide (IZO), indium gallium tin oxide (IGTO), and indium gallium oxide (IGO).

[0097] Polycrystalline semiconductor materials exhibit high mobility due to the rapid movement of charge carriers such as electrons and holes, resulting in low energy consumption and excellent reliability. Polycrystalline semiconductors can be made from polycrystalline silicon (poly-Si), but are not limited to this.

[0098] Amorphous semiconductor materials can be made of amorphous silicon (a-Si), but are not limited to this.

[0099] A gate insulating layer 142 may be disposed on the switching active layer 152 of the switching transistor 150 and the driving active layer 162 of the driving transistor 160. The gate insulating layer 142 may include an insulating material. The gate insulating layer 142 may be formed as a single layer made of inorganic materials or as multiple layers made of different inorganic materials. For example, the gate insulating layer 142 may be formed as a single layer or multiple layers of any one of silicon oxide (SiOx) film, silicon nitride (SiNx) film, and silicon oxynitride (SiON) film. For example, the gate insulating layer 142 can be formed by a single layer or multiple layers of inorganic films. For example, the single layer of inorganic film can be a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, or a silicon oxynitride (SiON) film, while the multiple layers of inorganic films can be formed by alternately stacking at least one of one or more layers of silicon oxide (SiOx) film, one or more layers of silicon nitride (SiNx) film, and one or more layers of silicon oxynitride (SiON) film and one or more layers of amorphous silicon (a-Si), but this disclosure is not limited thereto.

[0100] The switching gate electrode 151 of the switching transistor 150 and the driving gate electrode 161 of the driving transistor 160, which are made of metallic materials and spaced apart from each other, can be disposed on the gate insulating layer 142. The switching gate electrode 151 of the switching transistor 150 and the driving gate electrode 161 of the driving transistor 160 can be formed as a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or their alloys, but are not limited thereto.

[0101] A first interlayer insulating layer 143 may be disposed on the switching gate electrode 151 and the driving gate electrode 161. The first interlayer insulating layer 143 comprises an insulating material and can insulate the driving gate electrode 161 from the intermediate metal layer IM. The first interlayer insulating layer 143 may be formed by a single layer or multiple layers of inorganic films. For example, the single layer of inorganic film may be a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, or a silicon oxynitride (SiON) film, while the multiple layers of inorganic films may be formed by alternately stacking at least one of one or more layers of silicon oxide (SiOx) film, one or more layers of silicon nitride (SiNx) film, and one or more layers of silicon oxynitride (SiON) film and one or more layers of amorphous silicon (a-Si), but this disclosure is not limited thereto.

[0102] An intermediate metal layer IM may be disposed on the first interlayer insulating layer 143. The intermediate metal layer IM may comprise various metallic materials and overlap with the driving gate electrode of the driving transistor 160 to form a storage capacitor. The metallic materials may include, but are not limited to, any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or alloys thereof.

[0103] The second interlayer insulating layer 144 can be disposed on the intermediate metal layer IM. The second interlayer insulating layer 144 includes an insulating material and can insulate the switch gate electrode 151 from the switch source electrode 153 and the switch drain electrode 154 of the switch transistor 150. In addition, the second interlayer insulating layer 144 can insulate the intermediate metal layer IM from the drive source electrode and the drive drain electrode 164 of the drive transistor 160. The second interlayer insulating layer 144 can be formed by a single layer or multiple layers of inorganic films. For example, the single layer of inorganic film can be a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, or a silicon oxynitride (SiON) film, while the multiple layers of inorganic films can be formed by alternately stacking at least one of one or more layers of silicon oxide (SiOx) film, one or more layers of silicon nitride (SiNx) film, and one or more layers of silicon oxynitride (SiON) film and one or more layers of amorphous silicon (a-Si), but this disclosure is not limited thereto.

[0104] On the second interlayer insulating layer 144, the respective switch source electrode 153 and switch drain electrode 154 of the switching transistor 150, each comprising a metallic material, are spaced apart from each other, and the drive source electrode and drive drain electrode 164 of the driving transistor 160 may be spaced apart from each other. The switch source electrode 153 and switch drain electrode 154 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof, but are not limited thereto. The switch source electrode 153 and switch drain electrode 154 may be electrically connected to the switching active layer 152 through contact holes. The drive source electrode and drive drain electrode 164 may be electrically connected to the driving active layer 162 through contact holes. Furthermore, the switch drain electrode 154 of the switching transistor 150 may be electrically connected to the drive gate electrode 161 of the driving transistor 160 through contact holes.

[0105] In addition, gating pads, data pads DP and voltage pads VP can be set on the second interlayer insulating layer 144.

[0106] The gating pad is connected to the first connection line 181 via a contact hole to transmit the gating voltage to multiple sub-pixels SPX.

[0107] The data pad DP is connected to the second connection line 182 via a contact hole to transmit data voltage to multiple sub-pixels SPX.

[0108] The voltage pad VP is connected to the first connection line 181 via a contact hole to transmit the power supply voltage to multiple sub-pixels SPX.

[0109] Passivation layer 145 can be disposed on switching transistor 150, drive transistor 160, gating pad GP, data pad DP, and voltage pad VP. Passivation layer 145 includes an insulating material and protects various components disposed beneath passivation layer 145 from moisture and oxygen. Passivation layer 145 can be formed by a single or multiple inorganic film. For example, the single inorganic film can be a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, or a silicon oxynitride (SiON) film, while the multiple inorganic film can be formed by alternately stacking at least one of silicon oxide (SiOx) film, one or more silicon nitride (SiNx) film, and one or more silicon oxynitride (SiON) film and one or more amorphous silicon (a-Si), but this disclosure is not limited thereto.

[0110] Simultaneously, the gate insulating layer 142, the first interlayer insulating layer 143, the second interlayer insulating layer 144, and the passivation layer 145 are patterned identically to the buffer layer 141, so that they are formed only in the regions overlapping with the plurality of first plate patterns 121P. Similar to the buffer layer 141, the gate insulating layer 142, the first interlayer insulating layer 143, the second interlayer insulating layer 144, and the passivation layer 145 are also formed of inorganic materials. Therefore, during the stretching process of the display device 100, the gate insulating layer 142, the first interlayer insulating layer 143, the second interlayer insulating layer 144, and the passivation layer 145 may also be prone to cracking and damage. Therefore, the gate insulating layer 142, the first interlayer insulating layer 143, the second interlayer insulating layer 144, and the passivation layer 145 are not formed in the regions located between the plurality of first plate patterns 121P. However, the gate insulating layer 142, the first interlayer insulating layer 143, the second interlayer insulating layer 144 and the passivation layer 145 are patterned into a shape having a plurality of first plate patterns 121P so as to be formed only over the plurality of first plate patterns 121P.

[0111] A planarization layer 146 may be disposed on the passivation layer 145. The planarization layer 146 can planarize the upper portion of the switching transistor 150 and the upper portion of the driving transistor 160. The planarization layer 146 may be composed of a single layer or multiple layers and may be formed of an organic material. For example, the planarization layer 146 may be made of an organic insulating material such as acrylic resin, epoxy resin, polyimide, polyethylene, or silicon oxycarbide (SiOC), but is not limited thereto.

[0112] Reference Figures 2 to 4 Multiple connecting lines 181 and 182 can be disposed on multiple first line patterns 121L and multiple second line patterns 122L. The multiple connecting lines 181 and 182 can electrically connect the pads on the multiple first board patterns 121P and the multiple second board patterns 122P. The multiple connecting lines 181 and 182 can extend onto the multiple first board patterns 121P to electrically connect to the pads on the multiple first board patterns 121P. In the region located between the multiple first board patterns 121P, the multiple first line patterns 121L are not disposed in the region where the multiple connecting lines 181 and 182 are not disposed. Furthermore, although not shown in the figures, the multiple connecting lines 181 and 182 are disposed on the multiple second line patterns 122L to electrically connect to the pads on the multiple second board patterns 122P and the multiple first board patterns 121P.

[0113] The multiple connection lines 181 and 182 may include multiple first connection lines 181 and multiple second connection lines 182 disposed between multiple first board patterns 121P and multiple second board patterns 122P to connect pads on two adjacent board patterns.

[0114] Multiple first connecting lines 181 may be disposed on the top surface of the first line pattern 121L and extend at both ends above the first plate pattern 121P to contact the top and side surfaces of the planarization layer 146.

[0115] Connection patterns CNTs can be disposed on planarization layer 146. Connection patterns CNTs can electrically connect LED 170 to driving transistor 160 and low-potential power lines. For example, connection patterns CNTs can include a first connection pattern CNT1 and a second connection pattern CNT2. The first connection pattern CNT1 can electrically connect the drain of driving transistor 160 to the p-electrode 175 of LED 170, and the second connection pattern CNT2 can electrically connect the low-potential power line to the n-electrode 174 of LED 170. In this case, the second connection pattern CNT2 extends from connection lines 181 and 182 that transmit the low-potential power voltage, and is integrally formed with connection lines 181 and 182. Therefore, when the display device 100 is driven, different voltage levels applied to the first connection pattern CNT1 and the second connection pattern CNT2 are transmitted to the n-electrode 174 and the p-electrode 175, causing LED 170 to emit light.

[0116] A dam 147 may be formed on the connecting pattern CNT, connecting lines 181 and 182, and planarization layer 146. The dam 147 includes an insulating material and separates adjacent sub-pixels SPX. The dam 147 may be configured to cover at least a portion of the connecting pattern CNT, connecting lines 181 and 182, and planarization layer 146.

[0117] For example, the dam 147 may include a first dam and a second dam. The first dam may be made of an opaque material (e.g., a black material) to suppress optical interference between adjacent sub-pixels. The second dam may be made of a transparent material. The first and second dams may include, but are not limited to, light-shielding materials made of at least one of colored pigments, organic black materials, and carbon.

[0118] At the same time, the first and second dike sections can be formed as separate structures, or they can be formed as a single dike section.

[0119] The first and second dikes can be set at the boundaries between multiple sub-pixels and suppress color mixing of beams from multiple sub-pixels.

[0120] LED 170 can be disposed on the connecting pattern CNT. LED 170 may include an n-type layer 171, an active layer 172, a p-type layer 173, an n-electrode 174, and a p-electrode 175.

[0121] p-type layer 173 is disposed on the connecting pattern CNT, and n-type layer 171 can be disposed on p-type layer 173.

[0122] The active layer 172 (or the light-emitting layer) can be disposed between the n-type layer 171 and the p-type layer 173.

[0123] Furthermore, predetermined portions of the sequentially stacked n-type layer 171, active layer 172, and p-type layer 173 are etched, and an n-electrode 174 is disposed on a surface of the n-type layer 171 exposed in the etched area, while a p-electrode 175 may be disposed on a surface of the p-type layer 173 disposed in a non-etched area. An adhesive layer AD may be disposed between the LED 170 and the connection pattern CNT. The adhesive layer AD is disposed between the n-electrode 174 and p-electrode 175 of the LED 170 and the connection pattern CNT, such that the n-electrode 174 and p-electrode 175 are electrically connected to the connection pattern CNT through the adhesive layer AD.

[0124] The upper substrate 112 can be disposed on the LED 170 and the lower substrate 111. The upper substrate 112 can support various components disposed below the upper substrate 112.

[0125] A filler layer 190 may be disposed between the lower substrate 111 and the upper substrate 112. The filler layer 190 may completely fill the empty space between the lower substrate 111 and the upper substrate 112. For example, the filler layer 190 may be made of a curable adhesive.

[0126] Figure 5 This is a plan view of the display area and the first non-display area to the third non-display area of ​​a display device according to an exemplary embodiment of the present disclosure.

[0127] Reference Figures 1 to 5 As described above, the display device 100 according to an exemplary embodiment of the present disclosure may include a lower substrate 111, a pattern layer 120, a plurality of pixels PX, a gating driver GD, a data driver, a power supply PS, and an upper substrate 112.

[0128] In one exemplary embodiment, the pattern layer 120 may further include a plurality of third plate patterns 123P, a plurality of third line patterns 123L and a plurality of fourth line patterns 124L disposed in the second non-display area NA2, and a plurality of fourth plate patterns 124P and a plurality of fifth line patterns 125L disposed in the third non-display area NA3.

[0129] First, a plurality of third board patterns 123P are disposed in an island region ISA of a second non-display region NA2 located between a bonding region BDA and a link line region LNA, to connect to a plurality of pads formed on a base film 131 of a flexible film 130. For example, the third board patterns 123P may support a plurality of connection pads connected to the plurality of pads formed on the bonding region BDA of the base film 131 and a plurality of link lines connected thereto. The plurality of connection pads formed on the third board patterns 123P may be bonded to the flexible film 130 in the bonding region BDA. According to an exemplary embodiment, the width (e.g., horizontal width) of the island region ISA along the first direction X may be equal to the width (e.g., horizontal width) of the bonding region BDA along the first direction X.

[0130] The size (or area) of the multiple third-board patterns 123P can vary in each area. For example, the closer to the display area AA (e.g., the closer to the opposite direction of the second direction Y), the smaller the size (or area) of the multiple third-board patterns 123P.

[0131] Multiple link lines extend from the third board pattern 123P to the link line region LNA to transmit signals provided from multiple pads on the flexible film 130 to the display area AA. For example, one end of the multiple link lines is connected to multiple pads formed on the bonding area BDA of the base film 131, and the other end of the multiple link lines can be connected to multiple pixels PX of the display area AA. The link line region LNA is disposed between the island area ISA on which the third board pattern 123P is disposed and the display area AA, and gradually widens from the island area ISA to the display area AA (e.g., radially formed). Furthermore, the pattern layer 120 includes multiple fourth line patterns 124L disposed on the link line region LNA and connected to the third board pattern 123P disposed on the island area ISA, and multiple link lines can be disposed on the third board pattern 123P and the multiple fourth line patterns 124L. That is, the multiple link lines can be configured to extend from the third board pattern 123P to the multiple fourth line patterns 124L. (Refer to...) Figures 10 to 12 A more detailed description of the multiple connecting lines and the fourth line pattern 124L.

[0132] Next, multiple fourth board patterns 124P can be arranged in the third non-display area NA3 on both sides of the second non-display area NA2. For example, similar to the first board pattern 121P of the display area AA and the second board pattern 122P of the first non-display area NA1, the fourth board patterns 124P are arranged in an island shape spaced apart from each other, and the fifth line pattern 125L can connect adjacent fourth board patterns 124P. Power connection lines connected to the power supply PS can be provided on the fourth board patterns 124P and the fifth line pattern 125L.

[0133] In the following text, reference will be made to Figures 6A to 9IThe third plate pattern 123P and the third line pattern 123L, which are disposed in the island area ISA of the display device 100, will be described in more detail, and reference will be made to... Figures 10 to 12 The link lines provided in the link line area LNA of the display device 100 are described in more detail.

[0134] Figures 6A to 6H It is shown Figure 5 An enlarged plan view of an example of the island area of ​​a display device.

[0135] Figure 7A and Figure 7B This is an explanation Figure 5 A view of an example of a third line pattern included in a display device.

[0136] For example, Figures 6A to 6H Various exemplary embodiments of pattern layers 120, 120_1, 120_2, 120_3, 120_4, 120_5, 120_6, and 120_7 (e.g., various exemplary embodiments of third plate pattern 123P and third line pattern 123L) disposed on the island region ISA of the display device 100 are shown. Therefore, reference will be made to... Figure 6A The island area ISA of the display device 100 is described in detail, and for ease of description, in Figures 6B to 6H In the middle, the main description will be related to Figure 6A The different parts will not be repeated with redundant descriptions.

[0137] First, refer to Figure 5 and Figure 6A According to an exemplary embodiment of the present disclosure, the pattern layer 120 disposed on the island region ISA of the lower substrate 111 may include a plurality of third board patterns 123P and a plurality of third line patterns 123L.

[0138] The plurality of third plate patterns 123P may include a third-1 plate pattern 123P1 with a first size, a third-2 plate pattern 123P2 with a second size, a third-3 plate pattern 123P3 with a third size, and a third-4 plate pattern 123P4 with a fourth size, which are arranged sequentially and spaced apart from each other along the second direction Y (or the opposite direction of the second direction Y).

[0139] In one exemplary embodiment, the third-1 plate pattern 123P1, the third-2 plate pattern 123P2, the third-3 plate pattern 123P3, and the third-4 plate pattern 123P4 included in the plurality of third plate patterns 123P can have different sizes (or areas). The size (or area) of the plurality of third plate patterns 123P can gradually decrease in the opposite direction to the second direction Y (or the size (or area) of the plurality of third plate patterns 123P can gradually increase in the second direction Y). That is, the closer to the display area AA, the smaller the size (or area) of the plurality of third plate patterns 123P. In other words, among the plurality of third plate patterns 123P, the third-1 plate pattern 123P1, which is closest to the bonding area BDA where the flexible film 130 is disposed, has the largest first size (or first area). Furthermore, among the plurality of third plate patterns 123P, the third-4 plate pattern 123P4, which is closest to the link line area LNA, can have the smallest fourth size (or fourth area). In other words, the first dimension is larger than the second dimension, the second dimension is larger than the third dimension, and the third dimension can be larger than the fourth dimension.

[0140] According to exemplary embodiments, such as Figure 6A As shown, the third-1 plate pattern 123P1, the third-2 plate pattern 123P2, the third-3 plate pattern 123P3, and the third-4 plate pattern 123P4 have the same width along the vertical direction (e.g., the second direction Y), but have different widths along the horizontal direction (e.g., the first direction X). For example, in the case of multiple third plate patterns 123P, the width of the multiple third plate patterns 123P along the horizontal direction (e.g., the first direction X) gradually decreases in the opposite direction to the second direction Y (or the width of the multiple third plate patterns 123P along the horizontal direction (e.g., the first direction X) gradually increases in the second direction Y).

[0141] Furthermore, the dimensions of the multiple third plate patterns 123P gradually decrease in the opposite direction to the second direction Y. Therefore, the number of each of the third-1 plate pattern 123P1, the third-2 plate pattern 123P2, the third-3 plate pattern 123P3, and the third-4 plate pattern 123P4 per unit area gradually increases in the opposite direction to the second direction Y. For example, in Figure 6A The diagram shows a plurality of third plate patterns 123P, including one third-1 plate pattern 123P1, two third-2 plate patterns 123P2, four third-3 plate patterns 123P3, and eight third-4 plate patterns 123P4, but the exemplary embodiments of this disclosure are not limited thereto.

[0142] At the same time, even Figure 6AThe diagram shows that the pattern 123P1 of plate 3-1, the pattern 123P2 of plate 3-2, the pattern 123P3 of plate 3-3, and the pattern 123P4 of plate 3-4 are formed into quadrilateral shapes such as rectangles or squares, but the exemplary embodiments of this disclosure are not limited thereto.

[0143] The plurality of third line patterns 123L may include a third-1st line pattern 123L1 having a first shape. The third-1st line pattern 123L1 may connect third plate patterns 123P3 that are adjacent to each other along the second direction Y. For example, at a first position P1 between third-1st plate patterns 123P1 and third-2nd plate patterns 123P2 that are adjacent along the second direction Y, the third-1st line pattern 123L1 connects the adjacent third-1st plate patterns 123P1 and third-2nd plate patterns 123P2. At a second position P2 between a plurality of third-2nd plate patterns 123P2 that are adjacent along the second direction Y, the third-1st line pattern 123L1 connects the adjacent third-2nd plate patterns 123P2. At the third position P3 between adjacent 3-2 plate patterns 123P2 and 3-3 plate patterns 123P3 along the second direction Y, the 3-1 line pattern 123L1 connects the adjacent 3-2 plate patterns 123P2 and 3-3 plate patterns 123P3. At the fourth position P4 between multiple adjacent 3-3 plate patterns 123P3 along the second direction Y, the 3-1 line pattern 123L1 connects the adjacent 3-3 plate patterns 123P3. At the fifth position P5 between adjacent 3-3 plate patterns 123P3 and 3-4 plate patterns 123P4 along the second direction Y, the 3-1 line pattern 123L1 connects the adjacent 3-3 plate patterns 123P3 and 3-4 plate patterns 123P4. At the sixth position P6 between multiple adjacent third- and fourth plate patterns 123P4 along the second direction Y, the third-1 line pattern 123L1 can connect the adjacent third- and fourth plate patterns 123P4.

[0144] The plurality of third-1 line patterns 123L1 may have a wavy shape. For example, the plurality of third-1 line patterns 123L1 have a first wavy shape having a first length ratio. Here, the length ratio is defined by the ratio of the length of the line having a curved shape in the unstretched state (e.g., the distance between the two ends of the corresponding wiring line in the unstretched state without force applied to it to have a curved shape) to the length of the corresponding wiring line in the maximum extended state (e.g., the distance between the two ends of the corresponding wiring line that deforms into a straight line according to maximum tension when force is applied to it to extend it). For example, the smaller the length ratio, the fewer times the corresponding wiring line bends.

[0145] At the same time, as referenced Figure 5The multiple linking lines are formed on multiple third plate patterns 123P and multiple third line patterns 123L to extend into the linking line region LNA. For example, in the multiple third plate patterns 123P (e.g., in the 3-1 plate pattern 123P1, 3-2 plate pattern 123P2, 3-3 plate pattern 123P3, and 3-4 plate pattern 123P4), the multiple linking lines are formed as straight lines. Furthermore, in the multiple third line patterns 123L (e.g., in the 3-1 line pattern 123L1), the multiple linking lines may be formed as wavy lines following the shape of the 3-1 line pattern 123L1.

[0146] Furthermore, in the island region ISA, multiple third plate patterns 123P and multiple third line patterns 123L connecting adjacent third plate patterns 123P and having stretchability are configured to be freely stretched or bent. Therefore, the second non-display region NA2 (e.g., the island region ISA) together with the display region AA has stretchability for flexible deformation.

[0147] Furthermore, as described above, in the case of the display device 100 according to an exemplary embodiment of the present disclosure, the size (or area) of the third plate pattern 123P disposed in the island region ISA gradually decreases in the opposite direction to the second direction Y (i.e., the direction from the flexible film 130 to the display region AA). Therefore, when the display device 100 is stretched, the tensile stress of the third line pattern 123L and the multiple link lines disposed on the third line pattern 123L can be more effectively dispersed, thereby suppressing damage or cracking of the pattern layer 120 included in the display device 100.

[0148] In one exemplary embodiment, the plurality of third plate patterns 123P and the plurality of third line patterns 123L may be rigid patterns. For example, the plurality of third plate patterns 123P and the plurality of third line patterns 123L may be more rigid than the lower substrate 111 and the upper substrate 112.

[0149] The plurality of third plate patterns 123P and the plurality of third line patterns 123L, which serve as rigid substrates, can be formed of a plastic material with a lower flexibility than the lower substrate 111 and the upper substrate 112. For example, the plurality of third plate patterns 123P and the plurality of third line patterns 123L may include at least one of polyimide (PI), polyacrylate, and polyacetate. According to an exemplary embodiment, the plurality of third plate patterns 123P and the plurality of third line patterns 123L may include the same material. In this case, when the plurality of third plate patterns 123P and the plurality of third line patterns 123L include the same material, the plurality of third plate patterns 123P and the plurality of third line patterns 123L can be integrally formed.

[0150] The elastic modulus of the plurality of third plate patterns 123P and the plurality of third line patterns 123L can be higher than that of the lower substrate 111 and the upper substrate 112. For example, the elastic modulus of the plurality of third plate patterns 123P and the plurality of third line patterns 123L can be 1000 times higher than that of the lower substrate 111 and the upper substrate 112, but the exemplary embodiments of this disclosure are not limited thereto.

[0151] Next, refer to Figure 6B According to another exemplary embodiment of the present disclosure, the pattern layer 120_1 disposed on the island region ISA of the lower substrate 111 may include a plurality of third plate patterns 123P_1 and a plurality of third line patterns 123L_1.

[0152] The plurality of third plate patterns 123P_1 may include a third-1 plate pattern 123P1 with a first size, a third-2 plate pattern 123P2 with a second size, and a third-4 plate pattern 123P4 with a fourth size, which are arranged sequentially and spaced apart from each other along the second direction Y (or the opposite direction of the second direction Y).

[0153] In one exemplary embodiment, the third-1 plate pattern 123P1, the third-2 plate pattern 123P2, and the third-4 plate pattern 123P4 included in the plurality of third plate patterns 123P_1 may have different sizes (or areas). For example, the size (or area) of the plurality of third plate patterns 123P_1 may gradually decrease in the opposite direction to the second direction Y (or the size (or area) of the plurality of third plate patterns 123P_1 may gradually increase in the second direction Y). For example, as referenced Figure 6A Among the plurality of third plate patterns 123P_1, the first dimension (or first area) of the third-1st plate pattern 123P1, which is closest to the bonding region BDA where the flexible membrane 130 is disposed, is the largest. Furthermore, among the plurality of third plate patterns 123P_1, the fourth dimension (or fourth area) of the third-4th plate pattern 123P4, which is closest to the link line region LNA where multiple link lines are disposed, can be the smallest.

[0154] Furthermore, the dimensions of the multiple third plate patterns 123P_1 gradually decrease in the opposite direction to the second direction Y. Therefore, the number of each of the third-1 plate patterns 123P1, the third-2 plate patterns 123P2, and the third-4 plate patterns 123P4 per unit area can gradually increase in the opposite direction to the second direction Y. For example, in Figure 6BThe illustration shows a plurality of third plate patterns 123P_1, including one third-1 plate pattern 123P1, one third-2 plate pattern 123P2, and twenty third-4 plate patterns 123P4, but the exemplary embodiments of this disclosure are not limited thereto. For example, the plurality of third plate patterns include one third-1 plate pattern 123P1, one third-2 plate pattern 123P2, and twenty third-4 plate patterns 123P4 arranged sequentially in the opposite direction of the second direction. The first dimension of the third-1 plate pattern is larger than the second dimension of the third-2 plate pattern, and the second dimension of the third-2 plate pattern is larger than the fourth dimension of the third-4 plate pattern. The widths of the third-1, third-2, and third-4 plate patterns decrease in the opposite direction of the second direction along the first direction. The widths of the third-1, third-2, and third-4 plate patterns are the same in the second direction. However, this disclosure is not limited thereto.

[0155] In one exemplary embodiment, the plurality of third line patterns 123L_1 may include a third-1 line pattern 123L1 having a first shape and a third-2 line pattern 123L2 having a second shape.

[0156] The third-1 line pattern 123L1 can connect adjacent third plate patterns 123P_1 along the second direction Y. For example, at a first position P1 between adjacent third-1 plate patterns 123P1 and third-2 plate patterns 123P2 along the second direction Y, the third-1 line pattern 123L1 connects the adjacent third-1 plate patterns 123P1 and third-2 plate patterns 123P2. At a second position P2 between adjacent third-2 plate patterns 123P2 and third-4 plate patterns 123P4 along the second direction Y, the third-1 line pattern 123L1 connects the adjacent third-2 plate patterns 123P2 and third-4 plate patterns 123P4. At each of the third position P3, fourth position P4, fifth position P5 and sixth position P6 among the plurality of third-4 plate patterns 123P4 adjacent along the second direction Y, the third-1 line pattern 123L1 can connect the adjacent third-4 plate patterns 123P4.

[0157] Furthermore, the third-2 line pattern 123L2 can connect to the adjacent third plate pattern 123P_2 along the second direction Y. For example, at a first position P1 adjacent to the bonding area BDA where the flexible membrane 130 is provided, the third-2 line pattern 123L2 is disposed between the adjacent third-1 plate pattern 123P1 and the third-2 plate pattern 123P2 along the second direction Y to connect the adjacent third-1 plate pattern 123P1 and the third-2 plate pattern 123P2 along the second direction Y. For example, at the first position P1, the third-2 line pattern 123L2 is disposed between the adjacent third-1 line pattern 123L1 along the first direction X to connect the adjacent third-1 plate pattern 123P1 and the third-2 plate pattern 123P2 along the second direction.

[0158] Multiple line 3-1 patterns 123L1 and multiple line 3-2 patterns 123L2 can have a wavy shape. (Refer to...) Figure 7A and Figure 7B More specifically, the shapes of the third-1st line pattern 123L1 and the third-2nd line pattern 123L2 are set. The plurality of third-1st line patterns 123L1 have a first wavy shape with a first length ratio, and the plurality of third-2nd line patterns 123L2 may have a second wavy shape with a second length ratio.

[0159] In one exemplary embodiment, the first length ratio of the 3-1 line pattern 123L1 can be greater than the second length ratio of the 3-2 line pattern 123L2. Therefore, when a force is applied to the display device 100 along the second direction Y, the stretchability of the 3-2 line pattern 123L2 can be lower than the stretchability of the 3-1 line pattern 123L1. Therefore, in Figure 6B In an exemplary embodiment, excessive stretching of the island region ISA of the display device 100 can be suppressed by using the third-second line pattern 123L2, whose length ratio is less than the first length ratio. Therefore, damage or cracking of the pattern layer 120_1 included in the display device 100 can be suppressed more effectively.

[0160] At the same time, as referenced Figure 5 The multiple link lines are formed on multiple third plate patterns 123P_1 and multiple third line patterns 123L_1 to extend into the link line region LNA. For example, in the multiple third plate patterns 123P_1 (e.g., in the 3-1 plate pattern 123P1, 3-2 plate pattern 123P2, and 3-4 plate pattern 123P4), the multiple link lines are formed as straight lines. Furthermore, in the multiple 3-1 line patterns 123L1 of the multiple third line patterns 123L, the multiple link lines may be formed in a wavy shape along the shape of the 3-1 line pattern 123L1. According to an exemplary embodiment, the multiple link lines are not disposed above the 3-2 line pattern 123L2 to suppress excessive stretching.

[0161] Furthermore, as described above, the size (or area) of the third plate pattern 123P_1 disposed in the island region ISA gradually decreases in the opposite direction to the second direction Y (i.e., the direction from the flexible film 130 to the display area AA). Therefore, when the display device 100 is stretched, the tensile stress of the third line pattern 123L_1 and the multiple link lines disposed on the third line pattern 123L_1 can be more effectively dispersed.

[0162] Next, refer to Figure 6C According to another exemplary embodiment of the present disclosure, the pattern layer 120_2 disposed on the island region ISA of the lower substrate 111 may include a plurality of third plate patterns 123P_2 and a plurality of third line patterns 123L_2.

[0163] The plurality of third plate patterns 123P_2 may include a third-1 plate pattern 123P1 with a first size, a third-2 plate pattern 123P2 with a second size, a third-3 plate pattern 123P3 with a third size, and a third-4 plate pattern 123P4 with a fourth size, arranged sequentially and spaced apart from each other along the second direction Y (or the opposite direction of the second direction Y). Meanwhile, in Figure 6C In an exemplary embodiment, the third-1st plate pattern 123P1, the third-2nd plate pattern 123P2, the third-3rd plate pattern 123P3, and the third-4th plate pattern 123P4 included in the plurality of third plate patterns 123P_2 are consistent with those already referenced. Figure 6A The third-plate patterns 123P1, 123P2, 123P3, and 123P4, which are included in the multiple third-plate patterns 123P described, are substantially the same or similar. Therefore, redundant descriptions will not be repeated.

[0164] In one exemplary embodiment, the plurality of third line patterns 123L_2 may include a third-1 line pattern 123L1 having a first shape and a third-2 line pattern 123L2 having a second shape. Meanwhile, in Figure 6C In an exemplary embodiment, the third-1 line pattern 123L1 and the third-2 line pattern 123L2 included in the plurality of third line patterns 123L_2 are consistent with those already referenced. Figure 6B The third-line pattern 123L1 and the third-line pattern 123L2 included in the multiple third-line patterns 123L_1 described are substantially the same or similar. Therefore, redundant descriptions will not be repeated.

[0165] As described above, the size (or area) of the third plate pattern 123P_2 included in the pattern layer 120_2 disposed on the island region ISA gradually decreases in the opposite direction to the second direction Y (i.e., from the flexible film 130 to the display area AA). Therefore, when the display device 100 is stretched, the tensile stress of the third line pattern 123L_2 and the multiple connecting lines disposed on the third line pattern 123L_2 is more effectively dispersed. The multiple third line patterns 123L2_2 include the third-second line pattern 123L2 with lower stretchability to suppress excessive stretching of the island region ISA of the display device 100. Therefore, damage or cracking of the pattern layer 120_2 included in the display device 100 can be suppressed more effectively.

[0166] At the same time, Figure 6B and Figure 6C In the previous description, the third-2 line pattern 123L2 was only disposed in a first position P1 between the third-1 line pattern 123L1 adjacent along the first direction X, so as to connect the third-1 plate pattern 123P1 and the third-2 plate pattern 123P2 adjacent along the second direction Y. However, the exemplary embodiments of this disclosure are not limited thereto.

[0167] For example, refer to Figure 6D According to another exemplary embodiment of this disclosure, the pattern layer 120_3 disposed on the island region ISA of the lower substrate 111 may include a plurality of third board patterns 123P_3 and a plurality of third line patterns 123L_3. Here, the plurality of third board patterns 123P_3 are consistent with those already referred to Figure 6A The multiple third-board patterns 123P described are basically the same, so there is no need to repeat the redundant description.

[0168] The plurality of third line patterns 123L_3 may include a third-1 line pattern 123L1 having a first shape and a third-2 line pattern 123L2 having a second shape.

[0169] The third-second line pattern 123L2 can connect adjacent third plate patterns 123P_3 along the second direction Y. For example, at a first position P1 adjacent to the bonding area BDA where the flexible membrane 130 is provided, the third-second line pattern 123L2 is disposed between adjacent third-first plate patterns 123P1 and third-second plate patterns 123P2 along the second direction Y to connect the adjacent third-first plate patterns 123P1 and third-second plate patterns 123P2 along the second direction Y. At a second position P2 between adjacent third-second plate patterns 123P2 along the second direction Y, the third-second line pattern 123L2 connects the adjacent third-second plate patterns 123P2. At a third position P3 between adjacent 3-2 plate patterns 123P2 and 3-3 plate patterns 123P3 along the second direction Y, the 3-2 line pattern 123L2 connects the adjacent 3-2 plate patterns 123P2 and 3-3 plate patterns 123P3. At a fourth position P4 between multiple adjacent 3-3 plate patterns 123P3 along the second direction Y, the 3-2 line pattern 123L2 can connect the adjacent 3-3 plate patterns 123P3.

[0170] As mentioned above, with Figure 6B and Figure 6C Compared to the exemplary implementation, in Figure 6D In an exemplary embodiment, the third-second line pattern 123L2 for suppressing overstretching is provided not only at the first position P1, but also at the second position P2, the third position P3, and the fourth position P4. Therefore, the third-second line pattern 123L2 can effectively suppress overstretching of the island region ISA of the display device 100.

[0171] At the same time, even Figure 6D As already described, at each of the first position P1, second position P2, third position P3, and fourth position P4, a third-2 line pattern 123L2 having a second length ratio is disposed between a third-1 line pattern 123L1 having a first length ratio and adjacent along the first direction X. However, exemplary embodiments of this disclosure are not limited thereto.

[0172] For example, refer to Figure 6E According to another exemplary embodiment of this disclosure, the pattern layer 120_4 disposed on the island region ISA of the lower substrate 111 includes a plurality of third plate patterns 123P_4 and a plurality of third line patterns 123L_4. Figure 6E In an exemplary implementation, with Figure 6DCompared to the exemplary embodiments, the plurality of third line patterns 123L_4 may include only the third-1st line pattern 123L1 having a first length ratio. As described above, the plurality of third line patterns 123L_4 including only the third-1st line pattern 123L1 having the same shape makes the manufacturing process of the display device 100 more simplified.

[0173] Next, refer to Figure 6F According to another exemplary embodiment of the present disclosure, the pattern layer 120_5 disposed on the island region ISA of the lower substrate 111 may include a plurality of third plate patterns 123P_5 and a plurality of third line patterns 123L_5.

[0174] Multiple third plate patterns 123P_5 are arranged sequentially and spaced apart from each other along the second direction Y (or the opposite direction of the second direction Y). The multiple third plate patterns 123P_5 may include a third-1 plate pattern 123P1 with a first size, a third-5 plate pattern 123P5 with a fifth size, and a third-4 plate pattern 123P4 with a fourth size.

[0175] In one exemplary embodiment, the third-1 plate pattern 123P1, the third-5 plate pattern 123P5, and the third-4 plate pattern 123P4 included in the plurality of third plate patterns 123P_5 may have different dimensions (or areas). For example, the dimensions (or areas) of the plurality of third plate patterns 123P_5 may gradually decrease in the opposite direction to the second direction Y (or the dimensions (or areas) of the plurality of third plate patterns 123P_5 may gradually increase in the second direction Y). For example, among the plurality of third plate patterns 123P_5, the first dimension (or first area) of the third-1 plate pattern 123P1, which is closest to the bonding region BDA where the flexible membrane 130 is disposed, is the largest. The fifth dimension (or fifth area) of the third-5 plate pattern 123P5 adjacent to the third-1 plate pattern 123P1 along the second direction Y is smaller than the first dimension (or first area). The fourth dimension (or fourth area) of the pattern 123P4 on the 3rd-4th plate, which is adjacent to the pattern 123P5 on the 3rd-5th plate along the second direction Y, can be smaller than the fifth dimension (or fifth area).

[0176] Specifically, the third plate pattern 123P1, the third-fifth plate pattern 123P5, and the third-fourth plate pattern 123P4 included in the third plate pattern 123P3_5 have the same width along the horizontal direction (e.g., the first direction X) and have different widths along the vertical direction (e.g., the second direction Y). For example, in the case of multiple third plate patterns 123P_5, the width of the multiple third plate patterns 123P_5 along the vertical direction (e.g., the second direction Y) gradually decreases in the opposite direction to the second direction Y (or the width of the multiple third plate patterns 123P_5 along the vertical direction (e.g., the second direction Y) gradually increases in the second direction Y).

[0177] In one exemplary embodiment, the plurality of third line patterns 123L_5 may include a third-1 line pattern 123L1 having a first shape and a third-2 line pattern 123L2 having a second shape.

[0178] The plurality of third line patterns 123L_5 may include a third-1 line pattern 123L1 having a first shape. The third-1 line pattern 123L1 may connect third plate patterns 123P_5 that are adjacent to each other along the second direction Y. For example, at a first position P1 and a second position P2 between the third-1 plate pattern 123P1 and the third-5 plate pattern 123P5 that are adjacent along the second direction Y, the third-1 line pattern 123L1 connects the adjacent third-1 plate pattern 123P1 and the third-5 plate pattern 123P5. At a third position P3 between the third-5 plate pattern 123P5 and the third-4 plate pattern 123P4 that are adjacent along the second direction Y, the third-1 line pattern 123L1 connects the adjacent third-5 plate pattern 123P5 and the third-4 plate pattern 123P4. At the fourth position P4, fifth position P5, and sixth position P6 between a plurality of adjacent third- and fourth plate patterns 123P4 along the second direction Y, the third-first line pattern 123L1 can connect adjacent third- and fourth plate patterns 123P4. According to an exemplary embodiment, refer to... Figure 6FAt the first position P1 and the second position P2 between adjacent 3-1 plate patterns 123P1 and 3-5 plate patterns 123P5 along the second direction Y, two adjacent 3-1 line patterns 123L1 along the second direction Y are connected in each column to connect adjacent 3-1 plate patterns 123P1 and 3-5 plate patterns 123P5 along the second direction Y. For example, a plurality of third plate patterns include one 3-1 plate pattern, four 3-5 plate patterns, and 16 3-4 plate patterns arranged sequentially in the opposite direction of the second direction. The width of the 3-5 plate pattern along the first direction and the width of the 3-4 plate pattern along the first direction are each less than the width of the 3-1 plate pattern along the first direction, and the widths of the 3-5 plate pattern and the 3-4 plate pattern along the first direction are the same. The width of the 3-5 plate pattern along the second direction is greater than the width of the 3-4 plate pattern along the second direction. However, this disclosure is not limited thereto.

[0179] Next, refer to Figure 6G , Figure 6G The shape of pattern 123P_6 on the third plate is shown. Figure 6F A variant implementation.

[0180] Specifically, refer to Figure 6G According to another exemplary embodiment of the present disclosure, the pattern layer 120_6 disposed on the island region ISA of the lower substrate 111 may include a plurality of third board patterns 123P_6 and a plurality of third line patterns 123L_6.

[0181] The plurality of third plate patterns 123P_6 include a third-1 plate pattern 123P1 with a first size, a third-6 plate pattern 123P6 with a sixth size, a third-3 plate pattern 123P3 with a third size, and a third-4 plate pattern 123P4 with a fourth size, which are arranged sequentially and spaced apart from each other along the second direction Y (or the opposite direction of the second direction Y).

[0182] In one exemplary embodiment, the third-1 plate pattern 123P1, the third-6 plate pattern 123P6, the third-3 plate pattern 123P3, and the third-4 plate pattern 123P4 included in the plurality of third plate patterns 123P_6 may have different sizes (or areas). For example, the size (or area) of the plurality of third plate patterns 123P_6 may gradually decrease in the opposite direction to the second direction Y (or the size (or area) of the plurality of third plate patterns 123P_6 may gradually increase in the second direction Y). For example, among the plurality of third plate patterns 123P_6, the first size (or first area) of the third-1 plate pattern 123P1, which is closest to the bonding region BDA where the flexible membrane 130 is disposed, is the largest. The sixth size (or sixth area) of the third-6 plate pattern 123P6, which is adjacent to the third-1 plate pattern 123P1 along the second direction Y, is smaller than the first size (or first area). The third dimension (or third area) of the pattern 123P3 on plate 3-3, which is adjacent to the pattern 123P6 on plate 3-6 along the second direction Y, is smaller than the sixth dimension (or sixth area). The fourth dimension (or fourth area) of the pattern 123P4 on plate 3-4, which is adjacent to the pattern 123P3 on plate 3-3 along the second direction Y, can be smaller than the third dimension (or third area).

[0183] Specifically, the third-1 plate pattern 123P1, the third-6 plate pattern 123P6, the third-3 plate pattern 123P3, and the third-4 plate pattern 123P4 included in the plurality of third plate patterns 123P_6 may have different widths along the horizontal direction (e.g., the first direction X) and different widths along the vertical direction (e.g., the second direction Y). For example, in the case of multiple third plate patterns 123P_6, the widths of the multiple third plate patterns 123P_6 in the horizontal direction (e.g., the first direction X) and the widths in the vertical direction (e.g., the second direction Y) may gradually decrease in the opposite direction to the second direction Y.

[0184] At the same time, even Figure 6G The third line pattern 123L_6 shown in the figure only includes the third-1st line pattern 123L1 with a first shape having a first length ratio, but the exemplary embodiments of this disclosure are not limited thereto.

[0185] For example, further reference Figure 6H , Figure 6H The diagram shows the third line pattern 123L_7. Figure 6G A variant implementation.

[0186] Specifically, refer to Figure 6HAccording to another exemplary embodiment of this disclosure, a pattern layer 120_7 disposed on an island region ISA of a lower substrate 111 includes a plurality of third plate patterns 123P_7 and a plurality of third line patterns 123L_7. Meanwhile, the plurality of third plate patterns 123P_7 included in the pattern layer 120_7 are consistent with those already referenced... Figure 6G The multiple third plate patterns 123P_6 included in the described pattern layer 120_6 are basically the same or similar, so there is no need to repeat the redundant description.

[0187] The plurality of third line patterns 123L_7 may include a third-1 line pattern 123L1 having a first shape and a third-2 line pattern 123L2 having a second shape.

[0188] The third-2 line pattern 123L2 can connect adjacent third plate patterns 123P_3 along the second direction Y. For example, at the first position P1 and the second position P2 adjacent to the bonding area BDA where the flexible membrane 130 is provided, the third-2 line pattern 123L2 is disposed between the third-1 plate pattern 123P1 and the third-6 plate pattern 123P6 adjacent along the second direction Y to connect the third-1 plate pattern 123P1 and the third-6 plate pattern 123P6 adjacent along the second direction Y. At the third position P3 between the third-6 plate pattern 123P6 and the third-3 plate pattern 123P3 adjacent along the second direction Y, the third-2 line pattern 123L2 connects the adjacent third-6 plate pattern 123P6 and the third-3 plate pattern 123P3. At the fourth position P4 between multiple adjacent 3-3 plate patterns 123P3 along the second direction Y, the 3-2 line pattern 123L2 can connect the adjacent 3-3 plate patterns 123P3.

[0189] As described above, the third line pattern 123L_7 included in the pattern layer 120_7 includes a third-second line pattern 123L2 having a second length ratio for suppressing excessive stretching. Therefore, excessive stretching of the island region ISA of the display device 100 can be suppressed, thereby effectively suppressing damage or cracking of the pattern layer 120_7 included in the display device 100.

[0190] Figure 8 This is a graph illustrating an example of tensile stress applied to a line pattern when a display device according to an exemplary embodiment of the present disclosure is stretched.

[0191] Figures 9A to 9I This is a view illustrating an example of tensile stress applied to a display device when stretched according to an exemplary embodiment of the present disclosure.

[0192] At the same time, Figure 8In this process, pattern layer 120_C according to a comparative embodiment of the present disclosure and pattern layers 120, 120_1, 120_2, 120_3, 120_4, 120_5, 120_6 and 120_7 according to an exemplary embodiment of the present disclosure are stretched (e.g., when tension along the second direction Y is applied to the pattern layer). At this time, at the first position P1, second position P2, third position P3, fourth position P4, fifth position P5, and sixth position P6 of the third line patterns 123_C, 123L, 123L_1, 123L_2, 123L_3, 120_4, 120_5, 120_6, and 123L_7 with pattern layers 120_C, 120, 120, 120_1, 120_2, 123L_3, 120_4, 120_5, 120_6, and 123L_7, the maximum tensile stress (in) of the third line patterns 123_C, 123L, 123L_1, 123L_2, 123L_3, 123L_4, 123L_5, 123L_6, and 123L_7 is shown. Figure 8 (represented as "PI maximum strain" in Chinese).

[0193] In addition, Figure 9A The diagram illustrates the tensile stress (denoted as "STR") applied at each location of the patterned layer 120_C when stretched according to a comparative embodiment of the present disclosure. Figures 9A to 9I The image shows the stretching reference. Figures 6A to 6H The tensile stress (denoted as "STR") applied at each location of patterned layers 120, 120_1, 120_2, 120_3, 120_4, 120_5, 120_6 and 120_7 according to the exemplary embodiments of the present disclosure is described.

[0194] First, let's refer to... Figure 8 and Figure 9A , and already referenced Figures 5 to 6H Unlike the exemplary embodiments described, the plurality of third plate patterns 123P_C included in the pattern layer 120_C according to the comparative embodiment of this disclosure do not have different dimensions along the second direction Y. Furthermore, the plurality of third line patterns 123L_C do not include the third-second line pattern 123L2 having a second length ratio. Figure 8 and Figure 9AAs shown, when the pattern layer 120_C according to the comparative embodiment of the present disclosure is stretched as described above, a maximum tensile stress with a large deviation is obtained at the first position P1, second position P2, third position P3, fourth position P4, fifth position P5, and sixth position P6 where the third line pattern 123L_C is provided. That is, when the pattern layer 120_C according to the comparative embodiment of the present disclosure is stretched, the tensile stress is not distributed among the first position P1, second position P2, third position P3, fourth position P4, fifth position P5, and sixth position P6 where the third line pattern 123_C is provided, but rather concentrated in the portion adjacent to the bonding region BDA. Therefore, cracking or damage may occur in the pattern layer 120 of the display device 100.

[0195] Conversely, refer to Figure 8 and Figures 9B to 9I ,like Figure 9B , Figures 9D to 9I As shown, when multiple third plate patterns 123P, 123P_2, 123P_3, 123P_4, 123P_5, 123P_6 and 123P_7 have different dimensions along the second direction Y, and / or as shown... Figures 9C to 9E and Figure 9I As shown, when multiple third line patterns 123L_1, 123L_2, 123L_3, and 123L_7 include not only the third-1 line pattern 123L1 with a first length ratio, but also the third-2 line pattern 123L2 with a second length ratio to suppress overstretching, if pattern layers 120, 120_1, 120_2, 120_3, 120_4, 120_5, 120_6, and 120_7 are stretched, such as Figure 8As shown, the maximum tensile stress with a small deviation can be obtained in the first position P1, second position P2, third position P3, fourth position P4, fifth position P5 and sixth position P6 where the third line patterns 123L, 123L_1, 123L_2, 123L_3, 123L_4, 123L_5, 123L_6 and 123L_7 are set. In other words, in the pattern layers 120, 120_1, 120_2, 120_3, 120_4, 120_5, 120_6, and 120_7 according to the exemplary embodiments of this disclosure, tensile stress can be distributed at the first position P1, second position P2, third position P3, fourth position P4, fifth position P5, and sixth position P6 where the third line patterns 123L, 123L_1, 123L_2, 123L_3, 123L_4, 123L_5, 123L_6, and 123L_7 are provided. Therefore, damage or cracking of the third line patterns 123L, 123L_1, 123L_2, 123L_3, 123L_4, 123L_5, 123L_6, and 123L_7 included in the display device 100 can be suppressed.

[0196] Figure 10 This is an explanation Figure 5 A view of an example of link lines included in a display device.

[0197] Figure 11 It is shown Figure 10 An enlarged plan view of the example in Part A.

[0198] Figure 12 It shows along Figure 11 A cross-sectional view of an example taken from line V-V'.

[0199] Reference Figure 5 and Figure 10 Multiple link lines LL can be set on the junction area BDA, island area ISA, and link line area LNA.

[0200] Each of the multiple link lines LL has one end connected to multiple pads of the flexible film 130 in the bonding area BDA to transmit various signals from the printed circuit board PCB and the flexible film 130 to the display area AA. For example, each of the multiple link lines LL can transmit multiple wiring lines to the display area AA for data voltage or reference voltage.

[0201] Each of the multiple link lines LL may include a first line portion LLa, a second line portion LLb, and a third line portion LLc. The first line portion LLa is disposed on the island region ISA, and one end of it is connected to multiple pads of the bonding region BDA. The second line portion LLb is disposed on the link line region LNA and the portion of the link line region LNA that contacts the island region ISA, and one end of it is connected to the other end of the first line portion LLa. The third line portion LLc is disposed on the remaining area of ​​the link line region LNA excluding the area where the second line portion LLb is disposed, and one end of it is connected to the other end of the second line portion LLb.

[0202] For example, the first line portion LLa of each of the multiple link lines LL can be set in reference. Figures 6A to 6H The description is based on multiple third plate patterns 123P, 123P_1, 123P_2, 123P_3, 123P_4, 123P_5, 123P_6 and 123P_7, and multiple third line patterns 123L, 123L_1, 123L_2, 123L_3, 123L_4, 123L_5, 123L_6 and 123L_7.

[0203] Furthermore, the second line portion LLb of each of the multiple link lines LL extends from (or connects to) the first line portion LLa to extend entirely along the second direction Y. Additionally, the third line portion 11c of each of the multiple link lines LL extends from (or connects to) the second line portion LLb to extend entirely along the diagonal direction between the first direction X and the second direction Y.

[0204] More specifically, further refer to Figure 11 The pattern layer 120 may further include a fourth line pattern 124L disposed on the link line region LNA. The fourth line pattern 124L may be connected to the third plate pattern 123P disposed in the island region ISA. For example, in the third plate pattern 123P disposed in the island region ISA, the fourth line pattern 124L may be connected to the third-fourth plate pattern 123P4 closest to the link line region LNA.

[0205] The fourth line pattern 124L may include multiple fourth-line patterns 124L1 and multiple fourth-line patterns 124L2.

[0206] Each of the plurality of fourth-1 line patterns 124L1 extends along a second direction Y and may have a third shape. For example, each of the plurality of fourth-1 line patterns 124L1 may have a wavy shape (e.g., a sine wave shape). However, this disclosure is not limited thereto, and each of the plurality of fourth-1 line patterns 124L1 extends in a sawtooth pattern, or may be formed in various shapes (e.g., a shape that extends by connecting a plurality of rhomboid substrates at the vertices, or a shape in which semicircular or quarter-circular substrates are connected to each other).

[0207] Furthermore, the plurality of fourth-second line patterns 124L2 can be configured to surround the plurality of fourth-first line patterns 124L1. For example, some of the plurality of fourth-second line patterns 124L2 are configured to extend diagonally between the first direction X and the second direction Y, and the other fourth-second line patterns 124L2 can be configured to extend in a direction different from the diagonal direction (e.g., a vertical direction). For example, in the plurality of fourth-second line patterns 124L2, two fourth-second line patterns 124L2 extending diagonally and two fourth-second line patterns 124L2 extending in a direction perpendicular to the diagonal direction are formed into a rhombus shape. In addition, a fourth-first line pattern 124L1 can be provided in the four fourth-second line patterns 124L2 arranged in a rhombus shape.

[0208] Each of the plurality of fourth-second line patterns 124L2 may have a fourth shape. For example, each of the plurality of fourth-second line patterns 124L2 may have a wavy shape (e.g., a sine wave shape). However, this disclosure is not limited thereto, and each of the plurality of fourth-second line patterns 124L2 may extend in a zigzag pattern, or may be formed in various shapes (e.g., a shape that extends by connecting a plurality of rhomboid substrates at the vertices, or a shape in which semicircular or quarter-circular substrates are connected to each other).

[0209] In one exemplary embodiment, each of the plurality of fourth-1st line patterns 124L1 has a third length ratio, and each of the plurality of fourth-2nd line patterns 124L2 may have a fourth length ratio that is less than the third length ratio.

[0210] For example, considering the linewidth (critical dimension) of the multiple link lines LL disposed on the multiple fourth-second line patterns 124L2, the fourth length ratio of each fourth-second line pattern in the multiple fourth-second line patterns 124L2 can be designed to have a minimum length ratio. The third length ratio of each fourth-first line pattern in the multiple fourth-first line patterns 124L1 can be greater than the fourth length ratio. As described above, the multiple fourth line patterns 124L (i.e., the multiple fourth-first line patterns 124L1 and the multiple fourth-second line patterns 124L2) disposed on the link line region LNA are designed to have different length ratios to enhance the tensile durability of the display device 100.

[0211] In one exemplary embodiment, the plurality of fourth line patterns 124L (e.g., a plurality of fourth-1 line patterns 124L1 and a plurality of fourth-2 line patterns 124L2) may be rigid patterns. For example, the plurality of fourth-1 line patterns 124L1 and the plurality of fourth-2 line patterns 124L2 may be more rigid than the lower substrate 111 and the upper substrate 112.

[0212] The plurality of fourth-first line patterns 124L1 and the plurality of fourth-second line patterns 124L2, which serve as rigid substrates, can be formed of a plastic material with a lower flexibility than the lower substrate 111 and the upper substrate 112. For example, the plurality of fourth-first line patterns 124L1 and the plurality of fourth-second line patterns 124L2 may include at least one of polyimide (PI), polyacrylate, and polyacetate. According to an exemplary embodiment, the plurality of fourth-first line patterns 124L1 and the plurality of fourth-second line patterns 124L2 may include the same material. In this case, when the plurality of fourth-first line patterns 124L1 and the plurality of fourth-second line patterns 124L2 include the same material, the plurality of fourth-first line patterns 124L1 and the plurality of fourth-second line patterns 124L2 can be integrally formed. For example, one end and the other end of each of the plurality of fourth-1 line patterns 124L1 are connected at two opposite vertices along the second direction Y in a rhombus formed by four fourth-2 line patterns 124L2 to form an integral structure. For example, the fourth-1 line patterns 124L1 and the fourth-2 line patterns 124L2 can be connected by contact unit CT.

[0213] The elastic modulus of the plurality of fourth line patterns 124L (e.g., a plurality of fourth-1 line patterns 124L1 and a plurality of fourth-2 line patterns 124L2) can be higher than that of the lower substrate 111 and the upper substrate 112. For example, the elastic modulus of the plurality of fourth-1 line patterns 124L1 and the plurality of fourth-2 line patterns 124L2 can be 1000 times higher than that of the lower substrate 111 and the upper substrate 112, but the exemplary embodiments of this disclosure are not limited thereto.

[0214] Multiple link lines LL can be disposed on the fourth line pattern 124L. For example, the second line portion LLb of each link line in the multiple link lines LL can be disposed on multiple fourth-first line patterns 124L1, and the third line portion LLc of each link line in the multiple link lines LL can be disposed on multiple fourth-second line patterns 124L2. As described above, the multiple link lines LL are disposed on the stretchable fourth-first line patterns 124L1 and fourth-second line patterns 124L2 to extend or bend freely. Therefore, the second non-display area NA2 (e.g., the link line area LNA) together with the display area AA has stretchability to flexibly deform.

[0215] Furthermore, in the link line region LNA, multiple fourth line patterns 124L can also be provided in the portions where multiple link lines LL are not provided. For example, in the region of the link line region LNA where the second line portion LLb is provided with multiple link lines LL, the link lines LL are only provided on the fourth-1 line pattern 124L1, but not on the fourth-2 line pattern 124L2. In the region of the link line region LNA where the third line portion LLc is provided with multiple link lines LL, the link lines LL are only provided in the fourth-2 line pattern 124L2, but not on the fourth-1 line pattern 124L1. As described above, similarly, in the regions where multiple link lines LL are not provided, multiple fourth line patterns 124L, which serve as rigid patterns, are provided, thereby enhancing the tensile durability of the display device 100.

[0216] To describe the cross-sectional structure of the LNA in the link line region, further refer to... Figure 12 In the area of ​​the second line portion LLb of the link line region LNA, where the link line LL is provided, multiple insulation layers are provided on the 4-1 line pattern 124L1, and multiple link lines LL can be provided above any one of the multiple insulation layers.

[0217] For example, a buffer layer 141, a gate insulating layer 142, a first interlayer insulating layer 143, and a second interlayer insulating layer 144 are disposed on the fourth-first line pattern 124L1, and multiple link lines LL can be disposed on the second interlayer insulating layer 144. In addition, a passivation layer 145 and a planarization layer 146 are disposed on the multiple link lines LL to protect the link lines LL.

[0218] At the same time, Figure 12 The diagram only shows the cross-sectional structure of the region of the link line area LNA where the second line portion LLb is provided with the link line LL. However, in the region of the link line area LNA where the third line portion LLc is provided with the link line LL, multiple insulating layers are provided on the 4-2 line pattern 124L2, and multiple link lines LL can be provided above any one of the multiple insulating layers.

[0219] As described above, in the display device according to an exemplary embodiment of the present disclosure, in the non-display area disposed on one side of the display area, the size (or area) of the plate pattern bonded to the flexible film gradually decreases from the flexible film toward the display area. Therefore, when the display device is stretched, the tensile stress of the line patterns connecting adjacent plate patterns in the non-display area and the linking lines disposed on the line patterns can be effectively dispersed. Thus, damage or cracking of the pattern layer included in the display device can be suppressed.

[0220] Furthermore, in the case of the display device according to an exemplary embodiment of this disclosure, the length ratio of the line patterns connected to the plate pattern bonded to the flexible film in the non-display area can have different values ​​in each line pattern. Therefore, when the display device is stretched, excessive stretching of the non-display area can be suppressed, and damage or cracking of the pattern layer included in the display device can be suppressed.

[0221] Exemplary embodiments of this disclosure can also be described as follows:

[0222] According to one aspect of this disclosure, a display device includes: a lower substrate including a display area, a first non-display area located on both sides of the display area along a first direction, and a second non-display area located on one side of the display area along a second direction different from the first direction; a plurality of board patterns located in the display area, the first non-display area, and the second non-display area; and a plurality of line patterns located between the plurality of board patterns in the display area, the first non-display area, and the second non-display area, wherein the plurality of board patterns disposed in the second non-display area have different sizes.

[0228] The widths of the patterns on plates 3-1, 3-2, 3-3, and 3-4 can be the same in the second direction.

[0233] The 3-2 line pattern can be set between the adjacent 3-1 line patterns along the first direction.

[0234] Multiple third plate patterns may include a 3-1 plate pattern, a 3-2 plate pattern, and a 3-4 plate pattern arranged sequentially in a direction opposite to the second direction.

[0235] The first dimension of the pattern on plate 3-1 is larger than the second dimension of the pattern on plate 3-2, and the second dimension of the pattern on plate 3-2 is larger than the fourth dimension of the pattern on plate 3-4.

[0236] The width of the patterns on plates 3-1, 3-2, and 3-4 decreases in the direction opposite to the second direction along the first direction.

[0237] The widths of the patterns on plates 3-1, 3-2, and 3-4 are the same in the second direction.

[0238] Multiple third plate patterns may include a third-1 plate pattern, a third-5 plate pattern, and a third-4 plate pattern arranged sequentially in the opposite direction to the second direction.

[0239] The width of the pattern on plate 3-5 along the first direction and the width of the pattern on plate 3-4 along the first direction are both less than the width of the pattern on plate 3-1 along the first direction, and the width of the pattern on plate 3-5 along the first direction and the width of the pattern on plate 3-4 along the first direction are the same.

[0240] The width of the pattern on plates 3-5 along the second direction is greater than the width of the pattern on plates 3-4 along the second direction.

[0241] According to another aspect of this disclosure, a display device includes: a lower substrate including a display area, a first non-display area located on both sides of the display area along a first direction, and a second non-display area located on one side of the display area along a second direction different from the first direction; a plurality of board patterns located in the display area, the first non-display area, and the second non-display area; a plurality of line patterns located between the plurality of board patterns in the display area, the first non-display area, and the second non-display area; and a plurality of connecting lines located on the plurality of line patterns in the second non-display area.

[0242] The plurality of board patterns may include: a plurality of first board patterns located in a display area and spaced apart from each other; a plurality of second board patterns located in a first non-display area and spaced apart from each other; and a plurality of third board patterns located in a second non-display area and spaced apart from each other.

[0244] The plurality of fourth line patterns may include: a plurality of fourth-1 line patterns that extend along a second direction and have a third shape; and a plurality of fourth-2 line patterns that are configured to surround the plurality of fourth-1 line patterns and have a fourth shape different from the third shape.

[0245] Some of the 4-2 line patterns can extend along the diagonal direction between the first direction and the second direction, and other 4-2 line patterns can extend along a direction perpendicular to the diagonal direction.

[0246] The third length ratio of the 4-1 line pattern can be greater than the fourth length ratio of the 4-2 line pattern, and the length ratio can be defined by the ratio of the length in the unstretched state to the length in the maximum stretched state.

[0247] Multiple connecting lines may include: a first line portion located on multiple third plate patterns and multiple third line patterns in the island region; a second line portion located on multiple fourth-1 line patterns in the area of ​​the connecting line region that contacts the island region; and a third line portion located on multiple fourth-2 line patterns in the area of ​​the connecting line region other than the area where the second line portion is located.

[0248] Additional embodiments of this disclosure are described below.

[0249] For example, in some embodiments, the display device 100 may include: a substrate 111 having a display area AA; a first non-display area NA1 disposed on both sides of the display area along a first direction X; and a second non-display area NA2 disposed adjacent to one side of the display area along a second direction Y, which is transverse to the first direction. A plurality of board patterns 121P, 122P, and 123P are disposed in the display area AA, the first non-display area NA1, and the second non-display area NA2. A plurality of line patterns 121L, 122L, and 123L extend between adjacent board patterns in the plurality of board patterns. In the non-display areas NA1 and NA2, the board patterns are formed to have dimensions that vary with their position relative to the display area AA, such that board patterns closer to the display area have different dimensions compared to board patterns further away from the display area (see [link]). Figure 1 and Figure 2 ).

[0250] In some embodiments, the size of the board pattern 123P disposed in the second non-display area NA2 varies with its position relative to the display area AA. Specifically, board patterns closer to the display area (e.g., board pattern 123P4) are formed to have smaller dimensions than board patterns further away from the display area (e.g., board pattern 123P1 closer to the bonding area BDA of the flexible film 130). Therefore, in a plan view, the size of the board patterns gradually decreases towards the display area AA, thereby providing an arrangement that gradually transitions from a larger board pattern adjacent to the bonding area to a smaller board pattern adjacent to the display area (see [reference]). Figure 6A ).

[0251] In some embodiments, in a cross-sectional view, plate patterns 121P are disposed above substrate 111 and spaced apart from each other. Line patterns 121L are also disposed above substrate 111 and extend between adjacent plate patterns. In this way, the plate patterns and line patterns form an island structure supported above the substrate, wherein the line patterns bridge the spacing between the plate patterns (see...). Figure 4).

[0252] In some embodiments, multiple link lines may be disposed on the board pattern and line pattern in the second non-display area NA2. The link lines extend toward the display area AA and provide electrical interconnection between the pads disposed on the flexible film 130 in the bonding area BDA and the pixels PX formed in the display area AA.

[0253] In some embodiments, the second non-display area NA2 defines a link line area LNA that gradually widens or extends radially toward the display area AA. Multiple link lines disposed on the board pattern and line pattern extend over the widened area, such that the spacing between adjacent link lines varies toward the display area. Therefore, the arrangement of the link lines provides varying spacing in the direction toward the display area, thereby conforming to the geometry of the widened link line area (see [link to relevant documentation]). Figure 10 ).

[0254] In some embodiments, the board pattern 123P formed in the second non-display area NA2 has a uniform width along the first direction X, while having a different length along the second direction Y. For example, the third-first board pattern 123P1, the third-second board pattern 123P2, the third-third board pattern 123P3, and the third-fourth board pattern 123P4 have a common dimension along the first direction X, but different dimensions along the second direction Y, thereby providing a board pattern with varying lengths (see [link]). Figure 6A ).

[0255] In some embodiments, the flexible film 130 is bonded to the substrate 111 in the bonding region BDA. A board pattern 123P (e.g., 123P1) positioned closer to the bonding region of the flexible film is larger than a board pattern (e.g., 123P4) positioned closer to the display region AA. In this configuration, the size of the board patterns decreases along the direction from the flexible film 130 toward the display region AA, thereby providing a hierarchical arrangement (see [link]). Figure 5 ).

[0256] In some implementations, the number of board patterns per unit area increases toward the display area AA. For example, a relatively small number of larger board patterns (e.g., 123P1) are arranged in the portion of the second non-display area NA2 closer to the bonding area, while a large number of smaller board patterns (e.g., 123P4) are arranged in the portion of the second non-display area closer to the display area AA. Therefore, the density of board patterns per unit area increases toward the display area (see [link]). Figure 6A ).

[0257] like Figure 6B , Figure 7A and Figure 7BAs shown, the line pattern 123L formed in the second non-display area NA2 includes at least two sets of line patterns with different geometries when viewed in a plane. For example, the first set of line patterns may have a first wavy structure, while the second set of line patterns may be arranged with a different geometry.

[0258] like Figure 7A and Figure 7B As shown, one set of line patterns has a wavy shape in the planar view, while another set of line patterns has a zigzag shape. These line patterns with different shapes can be set within the second non-display area NA2 to provide different stretchability characteristics.

[0259] In reference Figures 6A to 6C In some of the described embodiments, the line patterns formed in the non-display areas are configured with different length ratios. By providing different length ratios, the tensile stress applied to the non-display areas is dispersed, and cracking of the pattern layer is suppressed. In this way, the varied line patterns enhance the mechanical durability of the display device when bent or stretched.

[0260] In some implementations, such as Figure 7A and Figure 7B As further shown, the line pattern is configured with a length ratio selected to control the stretching of the non-display area. By adjusting the length ratio of the line pattern, the stretching characteristics of the non-display area can be adjusted, thereby controlling the degree of elongation under applied stress and minimizing damage to the pattern layer.
