[0033] The inventive concept will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred illustrative embodiments of the inventive concept are shown. The inventive concept may, however, be embodied in many different forms and should not be construed as limited to the illustrative embodiments set forth herein. Rather, these illustrative embodiments are provided so that this disclosure will convey the scope of the inventive concept to those skilled in the art. Like reference numerals indicate like elements throughout the specification. In the drawings, the thickness of layers and regions are exaggerated for clarity.

[0034] It will also be understood that when a layer is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or intervening layers can also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

[0035] Although the terms "first," "second," etc. can be used herein to describe various elements, these elements should not be limited by these terms. These terms can be used to distinguish one element from another. Thus, a first element discussed below could be termed a second element without departing from the teachings of one or more illustrative embodiments. An element described as "first" need not necessarily be present before an element described as "second."

[0036] In the following, illustrative embodiments of the inventive concept will be described with reference to the accompanying drawings.

[0037] Figure 1 is a plan view of a display device according to an illustrative embodiment of the inventive concept, and Figure 2 is a schematic cross-sectional view of a display device according to an illustrative embodiment of the inventive concept.

[0038] As shown in Figure 1 illustrative embodiments, the first direction DR1 and the second direction DR2 can cross each other in different directions. For example, in a plan view defined in the first direction DR1 and the second direction DR2 as shown in Figure 1 , for ease of description, the first direction DR1 is defined as a vertical direction and the second direction DR2 is defined as a horizontal direction. Although in Figure 1 illustrative embodiments, the first direction DR1 and the second direction DR2 crossing each other are perpendicular to each other, the illustrative embodiments of the inventive concept are not limited thereto. In the following illustrative embodiments, a first side of the first direction DR1 represents an upward direction in a plan view, while an opposite second side of the first direction DR1 represents a downward direction in a plan view, a first side of the second direction DR2 represents a right direction in a plan view, while an opposite second side of the second direction DR2 represents a left direction in a plan view. However, the directions mentioned in the illustrative embodiments are understood to represent relative directions, and the embodiments are not limited to the above directions.

[0039] With reference to Figure 1 and Figure 2 illustrative embodiments, the display device 1 can be any electronic device that provides a display screen. For example, the display device 1 can include various large-, medium-, or small-sized electronic devices including televisions, notebooks, monitors, billboards, and Internet of Things, as well as portable electronic equipment such as mobile phones, smart phones, tablet personal computers (PCs), smart watches, watch phones, mobile communication terminals, electronic notebooks, electronic books, portable multimedia players (PMPs), navigators, and ultra-mobile PCs (UMPCs). However, the illustrative embodiments of the inventive concept are not limited thereto.

[0040] The display device 1 includes an active area AAR and a non-active area NAR. In the illustrative implementation, a partial portion of the display device 1 that displays an image is defined as a display area, and a partial portion that does not display an image is defined as a non-display area. An area in which a touch input is detected is defined as a touch area. The display area and the touch area can be included in the active area AAR. In the illustrative implementation, the display area and the touch area can overlap each other (e.g., in a thickness direction perpendicular to the first direction DR1 and the second direction DR2). For example, the active area AAR can be an area in which an image is displayed and a touch input is also detected. In the illustrative implementation, the shape of the active area AAR can be a rectangle or a rectangle with rounded corners. For example, as shown in the illustrative implementation of FIG. 1A, the shape of the active area AAR is a rectangle with rounded corners and the side extending in the first direction DR1 is relatively longer than the side extending in the second direction DR2. However, the illustrative implementation of the inventive concept is not limited thereto, and the active area AAR can have various shapes, such as a rectangle in which the side extending in the second direction DR2 is longer than the side extending in the first direction DR1, a square, other polygons, a circle, an ellipse, an irregular shape, etc. Figure 1

[0041] The non-active area NAR is disposed around the active area AAR. The non-active area NAR can be a bezel area. For example, as shown in the illustrative implementation of FIG. 1A, the non-active area NAR can surround all sides of the active area AAR. For example, in Figure 1 Figure 1 In the illustrative implementation of FIG. 1A, the non-active area NAR surrounds all four sides of the active area AAR. However, the illustrative implementation of the inventive concept is not limited thereto. For example, in another illustrative implementation, the active area AAR can extend to an edge of the display device 1 on at least one side, and the non-active area NAR can not be disposed around at least one side of the active area AAR. For example, the non-active area NAR can not be disposed around an upper side of the active area AAR or around left and right sides of the active area AAR.

[0042] ​​A signal line or a driving circuit for applying a signal to an active area AAR (e.g., a display area or a touch area) can be disposed in a non-active area NAR. The non-active area NAR can not include a display area. The non-active area NAR can also not include a touch area. However, illustrative embodiments of the inventive concept are not limited thereto, and in another illustrative embodiment, the non-active area NAR can include a portion of a touch area, and a sensing member such as a pressure sensor can be provided in the corresponding area. In some illustrative embodiments, the active area AAR can be exactly the same area as a display area in which an image is displayed, and the non-active area NAR can be exactly the same area as a non-display area in which an image is not displayed.

[0043] The display device 1 includes a display panel 10 that provides a display screen. Examples of the display panel 10 can include an organic light emitting display panel, a micro LED display panel, a nano LED display panel, a quantum dot light emitting display panel, a liquid crystal display panel, a plasma display panel, a field emission display panel, an electrophoretic display panel, and an electrowetting display panel. However, illustrative embodiments of the inventive concept are not limited thereto. Hereinafter, a case where the display panel 10 is an organic light emitting display panel is shown for convenience of explanation. However, illustrative embodiments of the inventive concept are not limited thereto, and in other illustrative embodiments, the inventive concept can be applied to other display panels.

[0044] The display panel 10 can include a plurality of pixels. In illustrative embodiments, the plurality of pixels can be arranged in a matrix form. In illustrative embodiments, a shape of each pixel can be rectangular or square in a plan view (e.g., in a plane defined by the first direction DR1 and the second direction DR2). However, illustrative embodiments of the inventive concept are not limited thereto, and in other illustrative embodiments, each pixel can have a rhombic shape with each side inclined with respect to the first direction DR1 or a plurality of other shapes. Each pixel can include a light emitting area. Each light emitting area can have the same shape as the pixel, or can have a different shape from the pixel. For example, when the pixel has a rectangular shape, the light emitting area of the corresponding pixel can have a plurality of shapes including a rectangle, a rhombus, a hexagon, an octagon, a circle, etc. Details of each pixel and each light emitting area will be described later.

[0045] The display device 1 can further include a touch sensing member that detects a touch input. In the illustrative implementation, the touch sensing member can be provided in the form of a panel or a film that is separate from the display panel 10 and attached to the display panel 10, or can be provided in the form of a touch layer that is positioned inside the display panel 10. In the following illustrative implementation, for convenience of explanation, the touch sensing member is provided in the form of a touch layer that is positioned inside the display panel 10 to be included in the display panel 10. However, the illustrative implementation of the inventive concept is not limited thereto.

[0046] In the illustrative implementation, the display panel 10 can include a flexible substrate including a flexible polymer material such as polyimide. Accordingly, the display panel 10 can be bent, warped, folded, curled, etc.

[0047] The display panel 10 can include a bending area BR in which the panel is bent. Based on the bending area BR, the display panel 10 can be divided into a main area MR positioned at a first side of the bending area BR and a sub area SR positioned at a second side of the bending area BR. For example, as shown in the illustrative implementation of FIG. 1, a portion of the display panel 10 positioned at an upper side (e.g., an upper side in the first direction DR1) of the bending area BR can include the main area MR, and a portion of the display panel 10 positioned at a lower side of the bending area BR can include the sub area SR. Figure 1

[0048] The display area of the display panel 10 is disposed in the main area MR. In the illustrative implementation, an edge of the main area MR surrounding the display area and the entire bending area BR and the entire sub area SR can be a non-display area. However, the illustrative implementation of the inventive concept is not limited thereto, and in other illustrative implementations, the bending area BR and / or the sub area SR can include at least one display area.

[0049] The main area MR can generally have a shape similar to a planar appearance of the display device 1. The main area MR can be a flat area positioned in a plane (e.g., a plane defined by the first direction DR1 and the second direction DR2). However, the illustrative implementation of the inventive concept is not limited thereto, and at least one of the remaining edges of the main area MR other than the edge connected to the bending area BR can be bent to form a curved surface, or bent in a vertical direction.

[0050] ​In the illustrative embodiment in which at least one of the remaining edges of the main area MR, other than the edge (side) connected to the bent area BR, can be bent or curved, a display area can also be provided at the corresponding edge. However, the illustrative embodiments of the inventive concept are not limited thereto, and the bent or curved edge can be a non-display area in which no image is displayed, or a display area and a non-display area can be mixed in the corresponding portion.

[0051] The bent area BR can be connected to one side of the main area MR. For example, as shown in the illustrative embodiment of FIG. 1A, the bent area BR can be connected to the lower short side of the main area MR. The width (e.g., the length in the second direction DR2) of the bent area BR can be less than the width (e.g., the length in the second direction DR2) of the main area MR. As shown in the illustrative embodiment of FIG. 1B, the bent area BR can be connected to the upper short side of the main area MR. The width (e.g., the length in the second direction DR2) of the bent area BR can be less than the width (e.g., the length in the second direction DR2) of the main area MR. Figure 1 Figure 1 The connection portion of the main area MR and the bent area BR can have an L-shaped cut shape, as shown in the illustrative embodiment of FIG. 1C. However, the illustrative embodiments of the inventive concept are not limited thereto.

[0052] In the bent area BR, the display panel 10 can be bent with a certain curvature in a downward direction in the thickness direction of the display device 1. In the illustrative embodiment, the bent area BR can have a constant radius of curvature. However, the illustrative embodiments of the inventive concept are not limited thereto, and in other illustrative embodiments, the bent area BR can have different radii of curvature for each section. As shown in the illustrative embodiment of FIG. 1D, the bent area BR can have a constant radius of curvature. However, the illustrative embodiments of the inventive concept are not limited thereto, and in other illustrative embodiments, the bent area BR can have different radii of curvature for each section. Figure 2 When the display panel 10 is bent in the bent area BR, the surface of the display panel 10 can be flipped over, as shown in the illustrative embodiment of FIG. 1E. For example, a portion of the front surface of the display panel 10, which faces upward when the display panel 10 is in an un-bent state at the bent area BR (as shown in FIG. 1A), can be changed to face outward by the bent area BR, and then face downward and be disposed adjacent to the rear surface of the display panel 10 (as shown in FIG. 1B). Figure 1 Figure 2

[0053] The sub-area SR (e.g., in the first direction DR1) extends from the bent area BR. When the display panel 10 is bent as shown in FIG. 1F, the sub-area SR can be disposed adjacent to the rear surface of the display panel 10, and when the bent area BR is in an un-bent state as shown in FIG. 1G, the sub-area SR can extend directly in a direction parallel to the main area MR. Figure 2 Figure 1 When the bent area BR is in a bent state, the sub-area SR can overlap the main area MR in the thickness direction of the display panel 10. As shown in the illustrative embodiment of FIG. 1H, the sub-area SR can overlap the main area MR in the thickness direction of the display panel 10. Figure 1 ​​​​In the illustrative embodiment shown in FIG. 1, the width (e.g., the length in the second direction DR2) of the sub-region SR can be equal to the width of the bending region BR. However, the illustrative embodiments of the present inventive concept are not limited thereto.

[0054] As shown in Figure 1 In the illustrative embodiment shown in FIG. 1, the sub-region SR can include a first pad region PA1 and a second pad region PA2 positioned farther (e.g., in the first direction DR1) from the bending region BR than the first pad region PA1. In the illustrative embodiment, the driving chip 20 can be disposed in the first pad region PA1 of the sub-region SR. The driving chip 20 can include an integrated circuit for driving the display panel 10. The integrated circuit can include an integrated circuit for image display by the display panel 10 and / or an integrated circuit for a touch unit. The integrated circuit for image display by the display panel 10 and the integrated circuit for the touch unit can be disposed as separate chips, or can be disposed integrated into one chip.

[0055] In the illustrative embodiment, the second pad region PA2 of the sub-region SR of the display panel 10 can include a plurality of display signal line pads and a plurality of touch signal line pads. The driving substrate 30 can be connected to the second pad region PA2 of the sub-region SR of the display panel 10. In the illustrative embodiment, the driving substrate 30 can be a flexible printed circuit board or a film.

[0056] Figure 3 is a schematic enlarged plan view of a portion FF according to an illustrative embodiment of the present inventive concept. Figure 1 is a schematic enlarged plan view of a portion FF according to an illustrative embodiment of the present inventive concept.

[0057] Referring to Figure 3 In the illustrative embodiment shown in FIG. 1, the display panel 10 includes a plurality of pixels arranged in a matrix shape. The plurality of pixels can be a plurality of color pixels. For example, in the illustrative embodiment shown in Figure 3 In the illustrative embodiment shown in FIG. 1, the plurality of pixels includes red pixels PX_R, green pixels PX_G, and blue pixels PX_B. However, the illustrative embodiments of the present inventive concept are not limited thereto. For example, in another illustrative embodiment, the plurality of pixels can further include white pixels. In another illustrative embodiment, cyan pixels, magenta pixels, and yellow pixels can be arranged instead of red pixels, green pixels, and blue pixels. Hereinafter, a case in which the display apparatus 1 includes red pixels PX_R, green pixels PX_G, and blue pixels PX_B will be described as an example for convenience of explanation.

[0058] The red pixels PX_R, the green pixels PX_G, and the blue pixels PX_B can be alternately arranged. As shown in Figure 3As shown in the illustrative embodiment, each of the red pixel PX_R, green pixel PX_G, and blue pixel PX_B can have a rectangular shape. The sizes of pixels PX_R, PX_G, and PX_B can be different from each other. For example, the blue pixel PX_B can be larger than the red pixel PX_R, and the red pixel PX_R can be larger than the green pixel PX_G. However, the size order of the red pixel PX_R, green pixel PX_G, and blue pixel PX_B is not limited to this, and the sizes of the red pixel PX_R, green pixel PX_G, and blue pixel PX_B can vary. In another illustrative embodiment, at least two of the red pixel PX_R, green pixel PX_G, and blue pixel PX_B can have the same size.

[0059] Each of the red pixel PX_R, green pixel PX_G, and blue pixel PX_B includes an organic light-emitting layer 122 (e.g., ...). Figure 6 (As shown in the diagram) and a first color filter 161_R, a second color filter 161_G, or a third color filter 161_B arranged for each pixel. In an illustrative embodiment, the first color filter 161_R may be a red color filter, the second color filter 161_G may be a green color filter, and the third color filter 161_B may be a blue color filter. A red pixel PX_R may include a red organic light-emitting layer 122_1 and the first color filter 161_R, a green pixel PX_G may include a green organic light-emitting layer 122_2 and the second color filter 161_G, and a blue pixel PX_B may include a blue organic light-emitting layer 122_3 and the third color filter 161_B. However, the illustrative embodiments of the present invention are not limited thereto. For example, in another embodiment, the red pixel PX_R, the green pixel PX_G, and the blue pixel PX_B may each include a white organic light-emitting layer and a first color filter 161_R, a second color filter 161_G, or a third color filter 161_B. White organic light-emitting layers can be formed by stacking two or more organic light-emitting layers.

[0060] The first red color filter 161_R selectively transmits red light. For example, the wavelength of the red light can be in the range of about 620 nm to about 750 nm. The green color filter selectively transmits green light. For example, the wavelength of the green light can be in the range of about 495 nm to about 570 nm. The blue color filter selectively transmits blue light. For example, the wavelength of the blue light can be in the range of about 450 nm to about 495 nm.

[0061] The first color filter 161_R can be provided in the red pixel PX_R, the second color filter 161_G can be provided in the green pixel PX_G, and the third color filter 161_B can be provided in the blue pixel PX_B. The first color filter 161_R, the second color filter 161_G, or the third color filter 161_B having different colors can be provided on each organic light emitting layer 122, thereby preventing color mixing in the pixel and increasing color reproducibility. Since the first color filter 161_R, the second color filter 161_G, and the third color filter 161_B absorb external light, reflection of external light can be reduced even when a polarizing plate or the like is not additionally provided.

[0062] In the illustrative embodiment, the shapes of the first color filter 161_R, the second color filter 161_G, and the third color filter 161_B can be substantially the same as the shape of the pixel described above. For example, as shown in the illustrative embodiment of FIG. 1A, when the shape of the pixel is a rhombus, the shape of each color filter can also be a rhombus. Figure 3

[0063] A black matrix 140 is provided at the boundary of each pixel. As shown in the illustrative embodiment of FIG. 1A, the black matrix 140 can be formed in a lattice shape to divide the pixels PX_R, PX_G, and PX_B. Figure 3

[0066] ​​​​​As described above, the base substrate 103 can be a flexible substrate. For example, in an illustrative embodiment, the base substrate 103 can be one of a plastic substrate and a film substrate including a polymeric organic material. For example, the base substrate 103 can include at least one compound selected from polystyrene, polyvinyl alcohol, polymethyl methacrylate, polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, cellulose triacetate, and cellulose acetate propionate. Further, the base substrate 103 can include a glass fiber reinforced plastic (FRP).

[0067] A buffer layer 111 is provided on the base substrate 103. The buffer layer 111 functions to smooth (e.g., planarize) the surface of the base substrate 103 and prevent penetration of moisture or external air. The buffer layer 111 can be an inorganic layer. The buffer layer 111 can be a single layer or multiple layers.

[0068] A plurality of thin film transistors TR is provided on the buffer layer 111. In an illustrative embodiment, the plurality of thin film transistors TR can be drive thin film transistors.

[0069] For example, the semiconductor layer CH is provided on the buffer layer 111. In an illustrative embodiment, the semiconductor layer CH can include amorphous silicon, polycrystalline silicon, or an organic semiconductor. In another illustrative embodiment, the semiconductor layer CH can be an oxide semiconductor. The semiconductor layer CH can include a channel region, and source and drain regions provided at both sides of the channel region and doped with impurities.

[0070] A gate insulating layer 112 is provided on the semiconductor layer CH. The gate insulating layer 112 can be an inorganic layer. The gate insulating layer 112 can be a single layer or multiple layers.

[0071] A first conductive layer DCL1 can be provided on the gate insulating layer 112. The first conductive layer DCL1 can include a gate electrode GE and a gate connection electrode GCE. As shown in the illustrative embodiment of FIG. 1, the gate electrode GE can be provided on the gate insulating layer 112, and the gate connection electrode GCE can be provided on the gate insulating layer 112 and electrically connected to the gate electrode GE. Figure 8As shown in the illustrative embodiment, the gate connection electrode GCE can be electrically connected to the thin-film transistor TR of each pixel via a second contact hole CNT2 through a first source connection electrode SCE1 disposed in the main region MR. The first source connection electrode SCE1 extends through the second contact hole CNT2 to contact the gate connection electrode GCE. The gate connection electrode GCE can also be connected to a second source connection electrode SCE2 via a third contact hole CNT3.

[0085] An encapsulation layer 116 is disposed on the second electrode 123. In an illustrative embodiment, the encapsulation layer 116 includes at least one inorganic layer and at least one organic layer. The at least one inorganic layer and the at least one organic layer may be stacked on top of each other. For example, as in... Figure 6 As shown in the illustrative embodiment, the encapsulation layer 116 is a multilayer comprising a first encapsulation inorganic layer 116a, an encapsulation organic layer 116b, and a second encapsulation inorganic layer 116c, which are sequentially stacked. In this illustrative embodiment, the first encapsulation inorganic layer 116a and the second encapsulation inorganic layer 116c may comprise materials selected from silicon oxide (SiO2). x ), silicon nitride (SiN) x ) and silicon nitride oxide (SiON) x The encapsulating organic layer 116b may include at least one compound selected from epoxy, acrylate and polyurethane acrylate.

[0086] As in Figure 6 As shown in the illustrative embodiment, the first color filter 161_R and the touch sensing member 130 can be disposed on the encapsulation layer 116. The first color filter 161_R can be directly disposed on the encapsulation layer 116. The encapsulation layer 116 and the touch sensing member 130 can be in direct contact with each other. For example, the touch sensing member 130 can be directly disposed on the encapsulation layer 116. Figure 6 As shown in the illustrative embodiment, the first touch conductive layer TCL1 of the touch sensing component 130 can be directly disposed on the encapsulation layer 116.

[0087] Reference Figure 4 and Figure 6In the illustrative embodiment, the touch sensing member 130 (e.g., a touch layer) can include a first touch conductive layer TCL1, a first touch insulating layer 131 disposed on the first touch conductive layer TCL1, and a second touch conductive layer TCL2 disposed on the first touch insulating layer 131.

[0088] The first touch conductive layer TCL1 can include a first touch bridge electrode CP1 electrically connecting sub-electrodes of each of the first sensing electrodes IE1_1 to IE1_8 adjacent in the second direction DR2. The second touch conductive layer TCL2 can include the plurality of first sensing electrodes IE1_1 to IE1_8 and the plurality of second sensing electrodes IE2_1 to IE2_4, and can further include a second touch bridge electrode CP2 electrically connecting sub-electrodes of each of the second sensing electrodes IE2_1 to IE2_4 adjacent in the first direction DR1. The first touch conductive layer TCL1 can be disposed directly on the encapsulation layer 116.

[0089] The plurality of first sensing electrodes IE1_1 to IE1_8 can extend along the second direction DR2 and can be arranged along the first direction DR1. The plurality of second sensing electrodes IE2_1 to IE2_4 can extend along the first direction DR1 and can be arranged along the second direction DR2.

Areas divided by the plurality of second sensing lines SPL2 can also overlap the red organic light emitting layer 122_1, the green organic light emitting layer 122_2, and the blue organic light emitting layer 122_3. In the illustrative embodiment, the areas divided by the plurality of first sensing lines SPL1 and the areas divided by the plurality of second sensing lines SPL2 can have a diamond shape. The diamond shape can include not only a diamond shape, but also a shape close to a diamond shape, which can deviate from a diamond shape due to processes and arrangements of sensing lines, etc.

[0091] As in Figure 7In the illustrative embodiment shown in FIG. 1, the first and second touch conductive layers TCL1 and TCL2 are electrically connected to each other. In the illustrative embodiment shown in FIG. 1, the first and second touch conductive layers TCL1 and TCL2 are electrically connected to each other through the first and second touch connection electrodes TCE1 and TCE2.

[0095] Hereinafter, for convenience of explanation, an illustrative embodiment in which the first touch conductive layer TCL1 can include the first touch bridge electrode CP1 electrically connecting sub-electrodes adjacent to each other in the second direction DR2 of each of the first sensing electrodes IE1_1 to IE1_8 and the second touch conductive layer TCL2 includes the plurality of first sensing electrodes IE1_1 to IE1_8 and the plurality of second sensing electrodes IE2_1 to IE2_4 and further includes the second touch bridge electrode CP2 electrically connecting sub-electrodes adjacent to each other in the first direction DR1 of each of the second sensing electrodes IE2_1 to IE2_4 will be described.

[0096] The second touch conductive layer TCL2 further includes the first and third touch connection electrodes TCE1 and TCE3, and the first touch conductive layer TCL1 includes the second touch connection electrode TCE2.

[0097] As in the illustrative embodiment of FIG. 1, in the main area MR, the first touch connection electrode TCE1 can be connected to the first source connection electrode SCE1 through the first contact hole CNT1 penetrating the first encapsulation inorganic layer 116a, the second encapsulation inorganic layer 116c, and the first touch insulation layer 131. Figure 8

[0098] ​In the bending region BR and the sub region SR, the second touch connection electrode TCE2 can overlap the second source connection electrode SCE2 in a thickness direction and can be electrically connected to the second source connection electrode SCE2. In the bending region BR and the sub region SR, the third touch connection electrode TCE3 can overlap the second touch connection electrode TCE2 in a thickness direction and can be electrically connected to the second touch connection electrode TCE2.

[0099] The plurality of first sensing lines SPL1 and the plurality of second sensing lines SPL2 can include a conductive material. In an illustrative implementation, the conductive material can include a low-resistance metal (such as at least one compound selected from silver (Ag), aluminum (Al), chromium (Cr), and nickel (Ni)), or can include a conductive nano-material (such as silver nanowires, carbon nanotubes, etc.).

[0100] Referring to Figure 4 In an illustrative implementation, the display device 1 can further include a second signal line SL2 and a third signal line SL3 passing through the first pad region PA1 and the second pad region PA2 and connected to the plurality of first sensing electrodes IE1_1 to IE1_8 and the plurality of second sensing electrodes IE2_1 to IE2_4. The second signal line SL2 can be electrically connected to the plurality of second sensing electrodes IE2_1 to IE2_4 of the touch sensing member 130. The third signal line SL3 can be electrically connected to the plurality of first sensing electrodes IE1_1 to IE1_8 of the touch sensing member 130.

[0101] The second signal line SL2 can include a first touch connection electrode TCE1 electrically connected to the plurality of second sensing electrodes IE2_1 to IE2_4 of the touch sensing member 130, a first source connection electrode SCE1 electrically connected to the first touch connection electrode TCE1 through a first contact hole CNT1, a gate connection electrode GCE electrically connected to the first source connection electrode SCE1 through a second contact hole CNT2, a second source connection electrode SCE2 connected to the gate connection electrode GCE through a third contact hole CNT3, and a second touch connection electrode TCE2 and a third touch connection electrode TCE3 stacked on the second source connection electrode SCE2.

[0102] As in Figure 5As shown in the illustrative embodiment, the third signal line SL3 may include a first touch connection electrode TCE1 electrically connected to the first sensing electrodes IE1_1 to IE1_8 of the touch sensing member 130, a first source connection electrode SCE1 electrically connected to the first touch connection electrode TCE1 through a first contact hole CNT1, a gate connection electrode GCE electrically connected to the first source connection electrode SCE1 through a second contact hole CNT2, a second source connection electrode SCE2 connected to the gate connection electrode GCE through a third contact hole CNT3, and a second touch connection electrode TCE2 and a third touch connection electrode TCE3 stacked on the second source connection electrode SCE2.

[0103] In addition, such as in Figure 4 As shown in the illustrative embodiment, the display panel 10 may further include a first signal line SL1 passing through the first pad region PA1 and the second pad region PA2 and electrically connected to the thin-film transistor TR of each pixel. (As shown in...) Figure 5 As shown in the illustrative embodiment, the first signal line SL1 may include a first source connection electrode SCE1 electrically connected to a thin-film transistor TR of each pixel, a gate connection electrode GCE electrically connected to the first source connection electrode SCE1 through a second contact hole CNT2, a second source connection electrode SCE2 electrically connected to the gate connection electrode GCE through a third contact hole CNT3, and a second touch connection electrode TCE2 and a third touch connection electrode TCE3 stacked on the second source connection electrode SCE2.

[0104] As in Figure 5 As shown in the illustrative embodiment, the first contact hole CNT1 is positioned further away from the bending region BR than the second contact hole CNT2 and the third contact hole CNT3, and the second contact hole CNT2 can be positioned further away from the bending region BR than the third contact hole CNT3.

[0105] As in Figure 6 As shown in the illustrative embodiment, the first touch conductive layer TCL1 can be directly disposed on the encapsulation layer 116. However, the illustrative embodiment of the present invention is not limited thereto, and in another illustrative embodiment, (e.g., in the thickness direction) an insulating layer having a single layer or multiple layers can be disposed between the encapsulation layer 116 and the first touch conductive layer TCL1.

[0106] The first touch insulating layer 131 can be disposed on the first touch conductive layer TCL1.

[0107] In an illustrative embodiment, the first touch insulating layer 131 may include an inorganic material. For example, the inorganic material may include silicon oxide (SiO2) selected from... x ), silicon nitride (SiN) x) and silicon oxynitride (SiON x In another illustrative implementation, the first touch insulating layer 131 can include an organic material. In this illustrative implementation, the organic material can include at least one material selected from the group consisting of acrylic resin, methacrylic resin, polyisoprene, vinyl resin, epoxy resin, urethane resin, cellulose resin, siloxane resin, polyimide resin, polyamide resin, and perylene resin.

[0108] The second touch conductive layer TCL2 can be disposed on the first touch insulating layer 131. The above-described sensing electrodes and touch bridge electrodes of the second touch conductive layer TCL2 can overlap the black matrix 140 and the pixel definition layer 115. Accordingly, visual recognition of an image in this area by a user can be prevented.

[0109] As shown in the illustrative implementation of FIG. 1A, the first color filter 161_R can be disposed directly on the encapsulation layer 116. In an illustrative implementation, which will be described in greater detail later, the first color filter 161_R can be formed before the touch sensing member 130 is formed and after the encapsulation layer 116 is formed. Figure 6

[0110] The first touch conductive layer TCL1 can be formed on the encapsulation layer 116 exposed by the first color filter 161_R. The first touch insulating layer 131 can be disposed on the first color filter 161_R. However, since the touch bridge electrodes of the first touch conductive layer TCL1 overlap the black matrix 140 and the pixel definition layer 115, the first color filter 161_R can not overlap the touch bridge electrodes of the first touch conductive layer TCL1. Similarly, since the touch bridge electrodes of the first touch conductive layer TCL1 do not overlap the first color filter 161_R, the touch bridge electrodes can be disposed directly on the encapsulation layer 116.

[0111] In contrast, the second color filter 161_G can be disposed on the first touch insulating layer 131. For example, as shown in the illustrative implementation of FIG. 1A, the second color filter 161_G can be disposed directly on the first touch insulating layer 131. Accordingly, the second color filter 161_G can be disposed on a different layer than the first color filter 161_R. In an illustrative implementation, the second color filter 161_G can be formed after the first touch conductive layer TCL1 and the first touch insulating layer 131 of the touch sensing member 130 are formed. Figure 6 The second touch conductive layer TCL2 can be disposed on the first touch insulating layer 131. For example, as shown in the illustrative implementation of FIG. 1A, the second touch conductive layer TCL2 can be disposed directly on the first touch insulating layer 131. Accordingly, the second touch conductive layer TCL2 can be disposed on a different layer than the first touch conductive layer TCL1. In an illustrative implementation, the second touch conductive layer TCL2 can be formed after the first touch conductive layer TCL1 and the first touch insulating layer 131 of the touch sensing member 130 are formed.

[0112] Figure 6 ​​As shown in the illustrative embodiment, the second touch conductive layer TCL2 can be formed on the first touch insulating layer 131 and then patterned. Since the touch bridge electrodes and sensing electrodes of the second touch conductive layer TCL2 overlap with the black matrix 140 and the pixel defining layer 115, the second color filter 161_G and the first color filter 161_R may not overlap with the touch bridge electrodes and sensing electrodes of the second touch conductive layer TCL2. In the illustrative embodiment, the touch bridge electrodes and sensing electrodes of the second touch conductive layer TCL2 can be directly disposed on the first touch insulating layer 131.

[0113] Reference Figure 8 and Figure 9 In the illustrative embodiment, the protective layer 114 and the pixel defining layer 115 can together with the dam auxiliary layer SPC to form a first dam DAM1 and a second dam DAM2. The first dam DAM1 and the second dam DAM2 can have a stacked structure in which the protective layer 114, the pixel defining layer 115 and the dam auxiliary layer SPC are continuously stacked and overlap each other.

[0114] As in Figures 8 to 9 As shown in the illustrative embodiment, the first dam section DAM1 and the second dam section DAM2 may be spaced apart from each other. The second dam section DAM2 may be positioned closer to the bending region BR than the first dam section DAM1. Each of the first dam section DAM1 and the second dam section DAM2 may prevent the encapsulation organic layer 116b of the encapsulation layer 116 from overflowing into the bending region BR.

[0115] The first dam DAM1 may overlap with the first source connection electrode SCE1 (e.g., in the thickness direction of the base substrate 103), and the second dam DAM2 may overlap with the gate connection electrode GCE and the first source connection electrode SCE1, and also overlap with the second contact hole CNT2.

[0116] The first contact hole CNT1, which penetrates the first touch insulating layer 131, the first encapsulation inorganic layer 116a, and the second encapsulation inorganic layer 116c, can be positioned between the first dam DAM1 and the second dam DAM2.

[0117] As in Figure 8 and Figure 9 As shown in the illustrative embodiment, the first encapsulation inorganic layer 116a and the second encapsulation inorganic layer 116c can be sequentially stacked on the first dam DAM1 and the second dam DAM2. The first encapsulation inorganic layer 116a and the second encapsulation inorganic layer 116c can be in direct contact with each other in these areas. The first encapsulation inorganic layer 116a can directly contact the first dam DAM1 and the second dam DAM2.

[0118] The first encapsulation inorganic layer 116a and the second encapsulation inorganic layer 116c may include a first contact hole CNT1. The first encapsulation inorganic layer 116a can directly contact the first source connection electrode SCE1.

[0119] As in Figure 5 , Figure 8 and Figure 9 As shown in the illustrative embodiment, the first touch connection electrode TCE1 of the second signal line SL2 and the first touch connection electrode TCE1 of the third signal line SL3 can be disposed on the first touch insulating layer 131 and can directly contact the upper surface of the first touch insulating layer 131. The first touch connection electrode TCE1 can be electrically connected to the first source connection electrode SCE1 through the first contact hole CNT1.

[0120] The buffer layer 111, the gate insulating layer 112, and the interlayer insulating layer 113 may include a bent opening portion in the bent region BR, which is an opening that exposes the upper surface of the base substrate 103.

[0121] The bent organic layer 170 may be disposed in the bent opening portion. In an illustrative embodiment, the bent organic layer 170 may include an organic insulating material. The organic insulating material of the bent organic layer 170 may include at least one of the materials described above for the protective layer 114.

[0122] The bending organic layer 170 can be formed in the bending opening portion to planarize the electrode, thereby preventing the formation of steps on the second source connection electrode SCE2 disposed thereon. In addition, the bending organic layer 170 may include organic material to prevent bending stress when the display device 1 is bent, thereby ensuring the bending flexibility of the display device 1.

[0123] The bent organic layer 170 can directly contact the lateral side surfaces of the buffer layer 111, gate insulating layer 112, and interlayer insulating layer 113 forming the bent opening portion. The lower surface of the bent organic layer 170 can directly contact the upper surface of the base substrate 103. The second source connection electrode SCE2 can be electrically connected to the gate connection electrode GCE through the third contact hole CNT3. The second source connection electrode SCE2 can be configured to span a portion of the main region MR, the bent region BR, and the sub-region SR. The second source connection electrode SCE2 can directly contact the bent organic layer 170. For example, as in Figure 8 As shown in the illustrative embodiment, the lower surface of the second source connection electrode SCE2 can directly contact the upper surface of the bent organic layer 170. Therefore, the first source connection electrode SCE1 and the second source connection electrode SCE2 can form source connection electrodes electrically connected to the source electrode SE and drain electrode DE of the thin-film transistor TR and overlapping with the bent organic layer 170.

[0124] As in Figures 8 to 9 As shown in the illustrative embodiment, the first color filter 161_R may include a plurality of first colored patterns separated from each other in the curved region BR and the sub-region SR. The plurality of first colored patterns of the first color filter 161_R may be directly disposed on the second source connection electrode SCE2. For example, as in... Figures 8 to 9 As shown in the illustrative embodiment, the lower surface of the plurality of first colored patterns of the first color filter 161_R can directly contact the upper surface of the second source connection electrode SCE2.

[0125] The second touch connection electrode TCE2 can be disposed on a plurality of first colored patterns separated from each other in the first color filter 161_R and on the second source connection electrode SCE2. For example, as in Figures 8 to 9 As shown in the illustrative embodiment, the lower surface of the second touch connection electrode TCE2 can directly contact the upper surface and lateral side surface of the plurality of first colored patterns of the first color filter 161_R, as well as the upper surface of the second source connection electrode SCE2. The second touch connection electrode TCE2 can overlap with the plurality of first colored patterns and the second source connection electrode SCE2, which are separated from each other (e.g., in the thickness direction of the base substrate 103). The second touch connection electrode TCE2 can be connected to the second source connection electrode SCE2 through the separation space CNT4 disposed between adjacent first colored patterns of the first color filter 161_R.

[0126] As in Figures 8 to 9 As shown in the illustrative embodiment, the second color filter 161_G may include a plurality of second colored patterns separated from each other in the curved region BR and the sub-region SR. The plurality of second colored patterns of the second color filter 161_G may be directly disposed on the second touch connection electrode TCE2. For example, as in... Figure 8 As shown in the illustrative embodiment, the lower surfaces of the plurality of second colored patterns of the second color filter 161_G can directly contact the upper surface of the second touch connection electrode TCE2. The third touch connection electrode TCE3 can (e.g., in the thickness direction of the base substrate 103) overlap with the second colored patterns and the second touch connection electrode TCE2, which are separated from each other. The third touch connection electrode TCE3 can be connected to the second touch connection electrode TCE2 through the separation space CNT5 located between adjacent second colored patterns. The lower surface of the third touch connection electrode TCE3 can directly contact the upper surface and lateral side surface of the second colored patterns of the second color filter 161_G.

[0127] The separation space CNT4 between the first colored patterns of the first color filter 161_R and the separation space CNT5 between the second colored patterns of the second color filter 161_G can overlap each other (e.g., in the thickness direction of the base substrate 103). The first colored patterns of the first color filter 161_R and the second colored patterns of the second color filter 161_G can overlap each other (e.g., in the thickness direction of the base substrate 103).

[0128] According to the illustrative embodiments, the first colored patterns and the second colored patterns are disposed in the bending region BR, thereby improving the bending characteristics of the display device 1.

[0129] Further, when the display device 1 is bent in the bending region BR, the second source connection electrode SCE2 can be disconnected. In the illustrative embodiments, the second touch connection electrode TCE2 and the third touch connection electrode TCE3, which are electrically connected with the second source connection electrode SCE2, are further disposed in the bending region BR, thereby reducing the possibility of disconnection of the first signal line SL1, the second signal line SL2, and the third signal line SL3.

[0130] As shown in the illustrative embodiments of Figure 6 In the main region MR, the third color filter 161_B can be disposed on the second touch conductive layer TCL2, such as on the first touch connection electrode TCE1. In the main region MR, the third color filter 161_B can overlap the second touch conductive layer TCL2 (e.g., overlap the first touch connection electrode TCE1) and can directly contact the second touch conductive layer TCL2. The third color filter 161_B can be disposed at the boundary between the main region MR and the bending region BR. However, in the illustrative embodiments, a partial portion of the third color filter 161_B can be disposed in the bending region BR.

[0131] As shown in the illustrative embodiments of Figure 6 In the main region MR, a black matrix 140 is disposed on the plurality of color filters. The black matrix 140 is disposed along the boundaries of the pixels and includes openings that expose the pixels.
