[0055] Hereinafter, exemplary embodiments will be described in more detail with reference to the accompanying drawings, wherein the same reference numerals represent the same elements throughout. However, the present invention can be implemented in various forms and should not be construed as being limited only to the embodiments shown herein. On the contrary, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey aspects and features of the present invention to those skilled in the art. Accordingly, processes, elements and techniques that are not necessary for a person of ordinary skill in the art to fully understand aspects and features of the present invention may not be described. Unless otherwise noted, the same reference numerals indicate the same elements throughout the attached drawings and written descriptions, and therefore their descriptions may not be repeated.

[0056] In the accompanying drawings, for the sake of clarity, the relative size of elements, layers and regions can be enlarged and / or simplified. Spatial relative words such as "beneath", "below", "lower", "under", "above", "upper", "top" and similar words can be used in this article for the convenience of explanation, to describe the relationship between an element or feature and other elements or features as shown in the figure. It should be understood that, in addition to the orientation shown in the accompanying drawings, spatial relative words are intended to also include different orientations of the device in use or in operation. For example, if the device in the figure is turned over, the element described as "below", "beneath" or "under" in other elements or features will be subsequently oriented to "above" in other elements or features. Therefore, the exemplary words "below" and "under" can include both the orientation of the top and the bottom. The device can be oriented in other ways (for example, rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein should be interpreted accordingly.

[0057] The exemplary embodiments are described herein with reference to various cross-sectional views corresponding to the schematic diagrams of the exemplary embodiments. Thus, it is expected that the changes in the shapes shown in the figures will be caused by, for example, manufacturing techniques and / or tolerances. Therefore, the embodiments described herein should not be interpreted as being limited to the specific shapes of the elements, layers and regions shown in the figures, but should include changes and deviations in the shapes caused by, for example, manufacturing processes. For example, a flat region may generally have rough and / or nonlinear features. In addition, the acute angles shown in the figures may be rounded. Therefore, the elements, layers and regions shown in the figures are schematic in nature, and the accompanying drawings are not intended to illustrate the precise shapes of the elements, layers and regions, and thus they are not intended to limit the spirit and scope of the present invention.

[0058] It should be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the spirit and scope of the present invention, the first element, first component, first region, first layer or first part described below may be referred to as the second element, second component, second region, second layer or second part.

[0059] It should be understood that when an element or layer is referred to as being "on", "connected to" or "coupled to" another element or layer, the element or layer may be directly on, directly connected to or coupled to another element or layer, or there may be one or more intermediate elements or layers. In addition, it should be understood that when an element or layer is referred to as being "between" two elements or layers, the element or layer may be the only element or layer between the two elements or layers, or there may be one or more intermediate elements or layers. On the other hand, it should be understood that when an element is referred to as being "directly on" another element or layer, "directly coupled to" or "directly connected to" another element or layer, there are no intermediate elements or layers. Other expressions describing the relationship between elements or layers, such as "directly between", "adjacent to" or "directly adjacent to", should be interpreted in the same or substantially the same manner.

[0060] The terms used herein are for the purpose of describing specific embodiments and are not intended to limit the present invention. Unless otherwise clearly indicated in the context, the singular forms "a" and "an" as used herein are also intended to include plural forms. It should also be understood that when the terms "comprise", "comprising", "include" and "including", "has", "have" and "having" are used in this specification, the existence of the stated features, integers, steps, operations, elements and / or parts is indicated, but the existence or addition of one or more other features, integers, steps, operations, elements, parts and / or their clusters is not excluded. As used herein, the term "or" indicates "and / or", and the term "and / or" includes any and all combinations of one or more of the related listed items. The expression after a column of elements such as "at least one of..." modifies the entire column of elements, rather than the individual elements in the column.

[0061] As used herein, the words "substantially", "about", "approximately" and similar words are used as words of approximation rather than words of degree, and are intended to take into account the inherent deviations of measured or calculated values ​​that will be recognized by those of ordinary skill in the art. For example, taking into account the errors related to the measurement and the measurement of a particular quantity (e.g., the limitations of the measurement system), the words "about", "approximately" and similar words used herein include the values ​​and indicate the acceptable deviation range of the particular value determined by those of ordinary skill in the art. For example, "about" may indicate within one or more standard deviations, or within ±30%, ±20%, ±10% or ±5% of the value. In addition, when describing embodiments of the present invention, the use of "may" refers to "one or more embodiments of the present invention". As used herein, the words "use", "using" and "used" may be considered to be synonymous with the words "utilize", "utilizing" and "utilized", respectively. Additionally, the word "exemplary" is intended to indicate an example or illustration.

[0062] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. It should also be understood that, unless explicitly defined as such herein, terms such as those defined in commonly used dictionaries should be interpreted as having the same meaning as they have in the context of the relevant technology and / or this specification, and should not be interpreted in an idealized or overly formal sense.

[0063] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0064] Figure 1 is a plan view showing a layout of a display device according to an exemplary embodiment of the present disclosure. Figure 2 is a cross-sectional view illustrating a portion of a display device in a bent state according to an exemplary embodiment of the present disclosure. Figure 3 is a cross-sectional view of a display device according to an exemplary embodiment of the present disclosure.

[0065] like Figure 1 As shown in FIG, the first direction DR1 may intersect with the second direction DR2. Figure 1 In a plan view (e.g., a view from a plane that is perpendicular or substantially perpendicular to the surface of the display device (or from a normal direction)), the first direction DR1 is shown as a vertical direction, and the second direction DR2 is shown as a horizontal direction. Accordingly, for convenience of illustration, in the following description, when observed from a top plan view (e.g., a view from a plane that is parallel or substantially parallel to the top surface of the display device (or from a normal direction)), an upward arrow pointing upward in the first direction DR1 indicates an upper side, a downward arrow pointing downward in the first direction DR1 indicates a lower side, a rightward arrow pointing to the right in the second direction DR2 indicates the right side, and a leftward arrow pointing to the left in the second direction DR2 indicates the left side. However, the present invention is not limited to the directions shown in the figures, and it should be understood that the directions indicated relative to the exemplary embodiments are relative directions, and the present invention is not limited to the directions described herein.

[0066] Reference Figures 1 to 3 As will be understood by those skilled in the art, the display device 1 may be a display device of any suitable electronic device for providing a display screen. For example, the display device 1 may be included in any suitable portable or non-portable electronic device for providing a display screen, such as a mobile phone, a smart phone, a tablet personal computer (PC), an electronic watch, a smart watch, a watch phone, a mobile communication terminal, an electronic notebook, an electronic book, a portable multimedia player (PMP), a navigation device, a game console, a digital camera, a television, a laptop computer, a monitor, an electronic billboard, an Internet of Things (IoT) device, and / or the like.

[0067] The display device 1 includes an active area AAR and a non-active area NAR. The display area of ​​the display device 1 may be defined as an area where an image is displayed, and the non-display area of ​​the display device 1 may be defined as an area where an image is not displayed. In addition, the touch area of ​​the display device 1 may be defined as an area where a touch input is sensed. Accordingly, the active area AAR may include a display area and a touch area. The display area and the touch area may overlap each other at the active area AAR (e.g., in the active area AAR or on the active area AAR). As a result, an image may be displayed at the active area AAR, and a touch input may be sensed at the active area AAR.

[0068] The active area AAR may have a shape corresponding to a rectangle with angled corners or a rectangle with rounded corners. Figure 1 The active area AAR is shown to have a shape corresponding to a rectangle with rounded corners, the shape having sides extending in the first direction DR1 longer than sides extending in the second direction DR2. However, the present disclosure is not limited thereto, and for example, the active area AAR may have various suitable shapes, such as a rectangular shape with angled corners having sides extending in the first direction DR1 longer than sides extending in the second direction DR2, a rectangular shape having sides extending in the second direction DR2 longer than sides extending in the first direction DR1 (e.g., having angled corners or rounded corners), a square, other suitable polygons, circles, ellipses, and / or the like.

[0069] The non-active region NAR is arranged around the active region AAR. The non-active region NAR may define (eg, may be) a border region. The non-active region NAR may surround all sides (eg, Figure 1 For example, the non-active region NAR may surround the periphery of the active region AAR. However, the present disclosure is not limited thereto. For example, the non-active region NAR may not be arranged adjacent to the upper side of the active region AAR, or may not be arranged adjacent to the left and / or right side of the active region AAR. In other words, in some embodiments, the non-active region NAR may partially surround the periphery of the active region AAR.

[0070] The signal line and / or driving circuit for applying a signal to the active area AAR (e.g., the display area and / or the touch area) of the display device 1 may be arranged at the non-active area NAR (e.g., in or on the non-active area NAR). The non-active area NAR may not include the display area. In addition, in some embodiments, the non-active area NAR may not include the touch area. In another exemplary embodiment, the non-active area NAR may include a portion (or part) of the touch area, and, for example, a sensor member such as a pressure sensor may be arranged in a portion of the touch area included in the non-active area NAR. In some exemplary embodiments, the active area AAR may correspond to a display area where an image is displayed (e.g., may be consistent with or substantially the same as the display area), and the non-active area NAR may correspond to a non-display area where an image is not displayed (e.g., may be consistent with or substantially the same as the non-display area). In other words, in some exemplary embodiments, the active area AAR may define a display area where an image is displayed, and the non-active area NAR may define a non-display area where an image is not displayed.

[0071] The display device 1 includes a display panel 10 for providing a display screen. Examples of the display panel 10 may include an organic light emitting display panel, a micro LED display panel, a nano LED display panel, a quantum dot display panel, a liquid crystal display panel, a plasma display panel, a field emission display panel, an electrophoretic display panel, an electrowetting display panel, and / or the like. Hereinafter, for the convenience of description, an organic light emitting display panel is provided as an example of the display panel 10, but the present disclosure is not limited thereto, and as will be understood by those of ordinary skill in the art, any other suitable display panel may be provided as the display panel 10.

[0072] The display device 1 may further include a touch member for sensing a touch input. The touch member may be provided as a panel or a separate film from the display panel 10 and may be connected to (e.g., attached to) the display panel 10, or the touch member may be provided in the display panel 10 (e.g., within or inside the display panel 10) in the form of a touch layer. In the following description, for the convenience of description, the touch member is described as being arranged in the display panel 10 (e.g., within or inside the display panel 10) as a part of the display panel 10 (e.g., included in the display panel 10), but the present disclosure is not limited thereto.

[0073] For example, the display panel 10 may include a flexible substrate including a flexible polymer material such as polyimide. Accordingly, the display panel 10 may be bent, curved, folded, and / or rolled.

[0074] The display panel 10 may include a bending region BR. The display panel 10 may be divided into a main region MR located on one side of the bending region BR and an auxiliary region SR located on the other side of the bending region BR. In other words, the main region MR may be defined at one end of the display panel 10 relative to the bending region BR, and the auxiliary region SR may be defined at the other end of the display panel 10 relative to the bending region BR.

[0075] The display area of ​​the display panel 10 is located at the main region MR (e.g., in or on the main region MR). The display area includes a plurality of pixels. According to an exemplary embodiment of the present disclosure, the edge portion of the display area at the main region MR (e.g., in or on the main region MR), the entirety of the curved region BR, and the entirety of the auxiliary region SR may define (e.g., may be) a non-display area. However, the present disclosure is not limited thereto. For example, in some embodiments, the curved region BR and / or the auxiliary region SR may also include a display area (or a portion of a display area).

[0076] When viewed from a top plan view (e.g., a view from a plane parallel or substantially parallel to the top surface of the display device 1 (or in the normal direction)), the main region MR may have a shape that is the same or substantially the same (e.g., or substantially similar) as the appearance of the display device 1. The main region MR may be a flat region located in one plane. However, the present disclosure is not limited to this. For example, in addition to the edge (e.g., side) connected to the curved region BR, at least one of the edges (e.g., side) of the main region MR may be bent to form a curved surface or may be bent at a right angle.

[0077] When at least one of the edges of the main region MR is bent or curved (for example, except for the edge (side) connected to the curved region BR), the display area (for example, a portion of the display area) may be arranged at at least one of the edges. However, the present disclosure is not limited thereto. For example, the bent or curved edge may be at a non-display area where an image is not displayed, or the display area and the non-display area may be arranged together.

[0078] The bending region BR is connected to one side of the main region MR in the first direction DR1. For example, the bending region BR may be connected to the lower side (e.g., the lower shorter side) of the main region MR. The width of the bending region BR may be smaller than the width of the main region MR (e.g., the width of the lower shorter side). The portion where the main region MR is connected (or intersected) with the bending region BR may be cut into an L shape to define a concave portion.

[0079] The display panel 10 may be bent downward with a curvature in a thickness direction (eg, in a direction away from the display surface) at (eg, in or on) the bending region BR. Figure 2It is shown that the display panel 10 may have a constant radius of curvature at the bending region BR, but the present disclosure is not limited thereto. For example, the display panel 10 may have different radii of curvature for different portions. As the display panel 10 is bent at the bending region BR, the surface of the display panel 10 may be reversed. For example, the upward-facing surface of the display panel 10 may be bent so that the surface faces outward (e.g., toward one side) at the bending region BR, and then faces downward (e.g., at the auxiliary region SR).

[0080] The auxiliary region SR extends from one side of the bending region BR. For example, in some embodiments, the auxiliary region SR may extend from a side of the bending region BR opposite to the main region MR. After the display device 1 is bent, the auxiliary region SR may extend in a direction parallel or substantially parallel to the surface of the main region MR. The auxiliary region SR may overlap with the main region MR in the thickness direction of the display panel 10. The width of the auxiliary region SR (e.g., the width in the second direction DR2) may be equal to or substantially equal to the width of the bending region BR, but the present disclosure is not limited thereto.

[0081] like Figure 1 As shown in the plan view of , the auxiliary region SR may include a first pad area PA1 and a second pad area PA2 positioned farther away from the bending area BR than the first pad area PA1. For example, the first pad area PA1 may be arranged between the bending area BR and the second pad area PA2 so that the first pad area PA1 is closer to the bending area BR than the second pad area PA2. The driving chip 70 may be arranged at the first pad area PA1 of the auxiliary region SR (for example, in or on the first pad area PA1).

[0084] When viewed from a top plan view as described above, the shape of the display member 20 may be the same or substantially the same (e.g., identical or substantially identical) as the shape of the display panel 10.

[0088] like Figure 3As shown in , the polarization member 40 may generally overlap with the main region MR in the thickness direction and may not overlap with the curved region BR (for example, may not be arranged in the curved region BR). The curved protective layer 50 may overlap with the curved region BR (for example, completely overlap with the curved region BR), and may have a portion that overlaps with (for example, may extend to) a portion (or portion) of each of the main region MR and the auxiliary region SR adjacent to the curved region BR. The side surface of the polarization member 40 may be in contact with the side surface of the curved protective layer 50. In other words, there may be no interval (or no gap) between the side surface of the polarization member 40 and the side surface of the curved protective layer 50. The boundary between the side surface of the curved protective layer 50 and the side surface of the polarization member 40 may be positioned at the main region MR (for example, in or on the main region MR).

For example, the planarization layer may include a suitable material such as acrylic and / or polyimide.

[0109] A plurality of first electrodes 121 may be disposed on the protective layer 115. The first electrodes 121 may be pixel electrodes each disposed in a corresponding pixel in the pixels. In addition, each of the first electrodes 121 may be an anode of a corresponding organic light emitting diode.

[0110] The first electrode 121 may be electrically connected to the drain electrode DE or the source electrode SE disposed on the substrate unit 101 through a through hole extending through (eg, passing through) the protection layer 115 .

[0112] The bank layer 116 is disposed on (e.g., above) the first electrode 121. The bank layer 116 includes a plurality of openings, each of which exposes at least a portion (or part) of a corresponding first electrode in the first electrode 121.

[0113] The emission layer (e.g., organic emission layer) 122 is arranged on the first electrode 121 exposed by the opening of the bank layer 116. The organic emission layer 122 may include (or may be) a color emission layer for emitting light of an appropriate color (e.g., a specific or desired color). For example, the organic emission layer 122 may include a red emission layer 122_1 for emitting red light, a green emission layer 122_2 for emitting green light, and a blue emission layer 122_3 for emitting blue light. The color emission layers may be arranged at pixels (e.g., in or on pixels), respectively.

[0114] In some exemplary embodiments, Figure 4 , the organic emission layer 122 may be formed as a single unit (e.g., a single layer). In other words, the pixels may share a single organic emission layer 122. The organic emission layer 122 may include (or be made of) a color emission layer for emitting light having an appropriate color. For example, the organic emission layer 122 may include (or may be) a blue emission layer for emitting blue light.

[0122] The touch member 30 may include a touch insulation layer 310 and a touch conductive layer TCL disposed on the touch insulation layer 310 .

[0123] The touch insulating layer 310 may be disposed on the second inorganic encapsulation layer 117 c.

The touch insulating layer 310 may insulate the touch conductive layer TCL from other conductive layers of the display member 20 .

[0124] In an exemplary embodiment, the touch insulating layer 310 may include an inorganic insulating material. For example, the inorganic insulating material may include a material selected from silicon oxide (SiO x ), silicon nitride (SiN x ) and silicon oxynitride (SiON x ).

In addition, the touch conductive layer TCL may include a touch driving signal line SLn2 electrically connected to the plurality of driving electrodes TE and a touch sensing signal line SLn1 electrically connected to the plurality of sensing electrodes RE.

[0126] The driving electrode TE may receive a touch driving signal from the touch driving circuit through the touch driving signal line SLn2, and may form a mutual capacitance with the adjacent sensing electrode RE. The sensing electrode RE is arranged adjacent to the driving electrode TE to which the touch driving signal is applied, and may transmit a capacitance value corresponding to the mutual capacitance (e.g., reflecting the mutual capacitance) to the touch driving circuit through the touch sensing signal line SLn1. The touch driving signal may include a plurality of pulses. The touch driving circuit may be implemented as a plurality of electrodes arranged in Figure 1 , but the present disclosure is not limited thereto.

[0127] The touch driving circuit may determine whether a touch is input based on a capacitance value between the driving electrode TE to which the touch driving signal is applied and the sensing electrode RE disposed adjacent to the driving electrode TE, and may calculate coordinates of the input touch.

[0128] The touch member 30 may include a touch sensor area TSA and a non-sensor area NSA, in which the drive electrodes TE, the sensing electrodes RE, the touch drive signal lines SLn2, and the touch sensing signal lines SLn1 are arranged, and the non-sensor area NSA is arranged around the touch sensor area TSA (e.g., to surround its periphery). The touch sensor area TSA may be located at a central area (e.g., the center) of the main area MR of the display device 1 or substantially at the central area, and the non-sensor area NSA may be located at an edge (e.g., a frame) of the main area MR and at a lower end (e.g., a lower side) of the touch sensor area TSA in the first direction DR1. The non-sensor area NSA may be located at each of the curved area BR and the auxiliary area SR of the display device 1 (e.g., in each of the curved area BR and the auxiliary area SR or on each of the curved area BR and the auxiliary area SR). The portion of the non-sensor area NSA located at the auxiliary area SR (e.g., in the auxiliary area SR or on the auxiliary area SR) also includes an auxiliary area. For example, as Figure 5 As shown in , the portion of the non-sensor area NSA located at the auxiliary area SR may also include a plurality of bridge portions MBP1 to MBP4 and a plurality of pad portions TPP1 and TPP2. A plurality of touch drive signal lines SLn2 and a plurality of touch sensing signal lines SLn1 extending from the touch sensor area TSA or the main area MR to the auxiliary area SR are electrically connected to each other (e.g., electrically merged or electrically linked) through bridge electrodes located at the bridge portions MBP1 to MBP4 (e.g., in the bridge portions MBP1 to MBP4 or on the bridge portions MBP1 to MBP4), which will be described in more detail below. The touch drive signal lines SLn2 and the touch sensing signal lines SLn1 electrically connected to each other (e.g., electrically merged or electrically linked) are connected to a plurality of pads arranged at the pad portions TPP1 and TPP2 (e.g., in the pad portions TPP1 and TPP2 or on the pad portions TPP1 and TPP2).

[0129] In more detail, the driving chip 70 may be arranged at a central area (e.g., center) of the auxiliary region SR. When viewed from a top plan view, a first side and a second side of the auxiliary region SR in the second direction DR2 may be defined relative to the driving chip 70. Each of the first bridge portion MBP1, the third bridge portion MBP3, and the first pad portion TPP1 may be located on a first side of the auxiliary region SR in the second direction DR2. Each of the second bridge portion MBP2, the fourth bridge portion MBP4, and the second pad portion TPP2 may be located on a second side of the auxiliary region SR in the second direction DR2. For example, the first bridge portion MBP1 and the second bridge portion MBP2 may be spaced apart from each other in the second direction DR2, the third bridge portion MBP3 and the fourth bridge portion MBP4 may be spaced apart from each other in the second direction DR2, and the first pad portion TPP1 and the second pad portion TPP2 may be spaced apart from each other in the second direction DR2.

[0130] The driving electrodes TE and the sensing electrodes RE may be arranged at the touch sensor area TSA (e.g., in or on the touch sensor area TSA). A plurality of driving electrodes TE may be associated with a single sensing electrode RE. For example, a plurality of driving electrodes TE may form a capacitance value (e.g., mutual capacitance) with a single sensing electrode RE. Different touch driving signals may be applied to a plurality of driving electrodes TE associated with a single sensing electrode RE, but the present disclosure is not limited thereto. Figure 5 As shown in , the length of a single sensing electrode RE in the first direction DR1 may be greater than the length of each of the driving electrodes TE associated with the single sensing electrode RE in the first direction DR1. The driving electrode TE associated with the single sensing electrode RE may be located on a side (e.g., one side) of the sensing electrode RE in the second direction DR2. The driving electrodes TE may be arranged along the first direction DR1 and may be spaced apart from each other along the first direction DR1.

[0131] A single sensing electrode RE and a plurality of driving electrodes TE associated with the single sensing electrode RE may form a touch unit. A plurality of touch units may be arranged in a matrix of rows and columns in the touch sensor area TSA.

[0132] As described above, the touch sensing signal line SLn1 and the touch driving signal line SLn2 are connected to the sensing electrode RE and the driving electrode TE forming the touch unit. According to one or more exemplary embodiments of the present disclosure, since the touch sensing signal line SLn1 and the touch driving signal line SLn2 are arranged on the touch conductive layer (e.g., a single touch conductive layer) TCL at the touch member 30 (e.g., in or on the touch member 30), if the touch pad extends to the first pad portion TPP1 and the second pad portion TPP2, there may be a large number of touch pads connected to the touch sensing signal line SLn1 and the touch driving signal line SLn2 connected to the sensing electrode RE and the driving electrode TE. As the number of touch pads arranged at the first pad portion TPP1 and the second pad portion TPP2 (e.g., in or on the first pad portion TPP1 and the second pad portion TPP2) increases, for example, the width of the auxiliary region SR in the second direction DR2 increases. As a result, there may not be enough space to arrange other elements (e.g., a stylus holder) at (e.g., in or on) the concave portion defined by the portion of the bending region BR cut into an L shape (e.g., a portion where the main region MR connects or intersects with the bending region BR). Therefore, the frame width may increase, and the space where the driver chip 70 is arranged at (e.g., in or on) the auxiliary region SR may be insufficient.

[0133] Reference Figure 6 , each of the driving electrode TE and the sensing electrode RE may have a mesh structure to transmit light output from the active area AAR of the display member 20. For example, each of the driving electrode TE and the sensing electrode RE may include a plurality of mesh holes EA, and a portion (or part) of the touch insulation layer 310 may be exposed through the mesh holes EA. The mesh holes EA of the driving electrode TE and the sensing electrode RE may overlap with the emission area of ​​the display member 20 in the third direction DR3 defining the thickness direction. In addition, the area of ​​the mesh holes EA may be larger than the area of ​​the emission area of ​​the display member 20. In this way, even if the driving electrode TE and the sensing electrode RE are located on the active area AAR of the display member 20, the light output from the active area AAR of the display member 20 may be transmitted through the driving electrode TE and the sensing electrode RE via the mesh holes EA.

[0134] In addition, like the driving electrodes TE and the sensing electrodes RE, the touch driving signal lines SLn2 and the touch sensing signal lines SLn1 respectively connected to the driving electrodes TE and the sensing electrodes RE may also include mesh holes EA.

For example, various suitable layouts of the multiple signal lines and the multiple touch electrodes may be used according to one or more other exemplary embodiments. For example, as described below, the touch signal line arranged at the first bridge portion MBP1 (e.g., in the first bridge portion MBP1 or on the first bridge portion MBP1) may also (e.g., or alternatively) be arranged at the second bridge portion MBP2 (e.g., in the second bridge portion MBP2 or on the second bridge portion MBP2).

[0164] As described above, according to one or more exemplary embodiments of the present disclosure, since the touch sensing signal line SLn1 and the touch driving signal line SLn2 are arranged on a single touch conductive layer TCL at the touch member 30 (e.g., in or on the touch member 30), if the touch pad extends to the first pad portion TPP1 and the second pad portion TPP2, there may be a large number of touch pads connected to the touch sensing signal line SLn1 and the touch driving signal line SLn2 connected to the sensing electrode RE and the driving electrode TE. As the number of touch pads arranged at the first pad portion TPP1 and the second pad portion TPP2 (e.g., in or on the first pad portion TPP1 and the second pad portion TPP2) increases, for example, the width of the auxiliary region SR in the second direction DR2 increases. As a result, there may not be enough space to arrange other elements (e.g., a stylus holder) at the concave portion cut into an L shape at the bending region BR (e.g., in or on the bending region BR). In this way, the width of the frame may increase, and there may not be enough space to arrange the driving chip 70 at the auxiliary region SR (for example, in the auxiliary region SR or on the auxiliary region SR). In this regard, according to one or more exemplary embodiments of the present disclosure described above, a plurality of touch signal lines connected to a plurality of touch electrodes may be electrically connected to each other (for example, electrically merged or electrically linked) by bridging electrodes arranged in a direction intersecting with the direction in which the touch signal lines extend to the pads. Accordingly, the number of touch pads can be reduced. In addition, as described above, the bridging portion at which the bridging electrode is arranged (for example, therein or on it) may also include, for example, touch signal lines are first connected to each other (for example, merged or linked), such as at the first bridging portion and the second bridging portion, and, for example, touch signal lines that are connected (for example, merged or linked) are connected to each other again (for example, merged or linked), such as at the third bridging portion and the fourth bridging portion. Accordingly, the number of touch pads can be further reduced (for example, significantly reduced).

[0165] In addition, the touch signal lines connected to each other (e.g., merged or linked) at the first bridge portion MBP1 on one side of the driving chip 70 in the second direction DR2 (e.g., in the first bridge portion MBP1 or on the first bridge portion MBP1), and the touch signal lines connected to each other (e.g., merged or linked) at the second bridge portion MBP2 on the opposite side of the driving chip 70 in the second direction DR2 (e.g., in the second bridge portion MBP2 or on the second bridge portion MBP2) can be extended to the third bridge portion MBP3 to be connected to each other (merged or linked). Accordingly, the number of touch pads can be further reduced. As a result, a sufficient area for mounting the driving chip 70 on the display panel 10 can be provided. In addition, the dead zone can be reduced in the touch pad unit.

In addition, in some embodiments, some of the bridging electrodes of the touch member may be arranged on the first conductive layer DCL1 and / or the second conductive layer DCL2, and some other bridging electrodes may be arranged on the third conductive layer DCL3.

[0173] Fig.17 is a view illustrating a layout of signal lines arranged in a main region, a bending region, and an auxiliary region according to another exemplary embodiment. Fig.18 yes Fig.17 A magnified view of a portion of . Fig.19 is along Fig.18 A cross-sectional view taken along line XIX-XIX'.

[0174] according to Figures 17 to 19 The touch member of the display device of the exemplary embodiment shown in is different from the touch member of the display device according to one or more of the above-described exemplary embodiments in that the bridge electrodes overlap each other in the thickness direction.

[0175] In more detail, in the touch member of the display device according to the present exemplary embodiment, the bridge electrodes may be arranged so that they overlap each other in the thickness direction. Fig.17 As shown in , the third bridging electrode BE3 and the fourth bridging electrode BE4_1 may overlap each other in the thickness direction. In this case, the third bridging electrode BE3 and the fourth bridging electrode BE4_1 may be arranged on layers different from each other so that the third bridging electrode BE3 and the fourth bridging electrode BE4_1 overlap each other. For example, in some embodiments, the third bridging electrode BE3 may be arranged on the first conductive layer DCL1, and the fourth bridging electrode BE4_1 may be arranged on the second conductive layer DCL2, but the present disclosure is not limited thereto, and the third bridging electrode BE3 and the fourth bridging electrode BE4_1 may be arranged on any appropriate conductive layer different from each other in the conductive layer. Since the third bridging electrode BE3 is arranged on a layer (e.g., the first conductive layer DCL1) different from the layer (e.g., the second conductive layer DCL2) on which the fourth bridging electrode BE4_1 is arranged, even if the third bridging electrode BE3 and the fourth bridging electrode BE4_1 overlap each other in the thickness direction, a short circuit is not likely to occur between them. On the other hand, in some embodiments, the third bridging electrode BE3 may be disposed on the second conductive layer DCL2, and the fourth bridging electrode BE4_1 may be disposed on the first conductive layer DCL1.

[0176] According to the present exemplary embodiment, the area occupied by the bridge electrode when viewed from a top plan view can be reduced by arranging the bridge electrodes on different layers so that they overlap each other in the thickness direction.

[0177] Although according to Fig.17 In the exemplary embodiment shown in FIG. 1 , the third bridging electrode BE3 and the fourth bridging electrode BE4_1 overlap each other in the thickness direction and are arranged on different layers, but those skilled in the art will appreciate that such an overlapping structure can be implemented in various appropriate combinations of various bridging electrodes. For example, as described above with reference to Fig.16 As described, the bridging electrodes arranged at the third bridge portion MBP3 and the fourth bridge portion MBP4 (for example, in the third bridge portion MBP3 and the fourth bridge portion MBP4 or on the third bridge portion MBP3 and the fourth bridge portion MBP4) may be arranged on the first conductive layer DCL1, the second conductive layer DCL2 and / or the third conductive layer DCL3. Accordingly, some of the bridging electrodes arranged at the third bridge portion MBP3 and the fourth bridge portion MBP4 (for example, in the third bridge portion MBP3 and the fourth bridge portion MBP4 or on the third bridge portion MBP3 and the fourth bridge portion MBP4) and arranged on different layers among the first conductive layer DCL1 to the third conductive layer DCL3 may overlap each other in the thickness direction.
