[0002] This application claims priority to Korean Patent Application No. 10-2019-0072817, filed on June 19, 2019, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure relates to display devices and methods for manufacturing display devices. Background Technology

[0004] Electronic devices that provide images to users (such as smartphones, tablet PCs, digital cameras, laptops, navigation devices, smart TVs, etc.) include display devices for displaying images. Such display devices include display panels for generating and displaying images, as well as various input devices.

[0005] Sensing components capable of detecting sensor inputs (e.g., touch inputs) can be used in display devices, such as those used in smartphones and tablet PCs.

The sensing component may include multiple conductive layers and multiple insulating layers that insulate the conductive layers from each other. However, external air, moisture, etc., may penetrate through the exposed conductive layers of the sensing component, causing it to malfunction. Summary of the Invention

[0063] Exemplary embodiments of the present disclosure will be described more fully below with reference to the accompanying drawings. Throughout the drawings, the same reference numerals may denote the same elements.

[0064] It will be understood that when a component, such as a membrane, region, layer, or element, is referred to as being "on," "connected to," "attached to," or "adjacent to" another component, the component may be directly on, directly connected to, directly attached to, or directly adjacent to the other component, or there may be intermediate components. It will also be understood that when a component is referred to as being "between" two components, the component may be the only component between the two components, or there may be one or more intermediate components. It will also be understood that when a component is referred to as "covering" another component, the component may be the only component covering the other component, or one or more intermediate components may also cover the other component. Other terms used to describe relationships between components should be interpreted in a similar manner.

[0065] It will be understood that the terms “first,” “second,” “third,” etc., are used herein to distinguish one element from another, and these elements are not limited by these terms. Thus, a “first” element in an exemplary embodiment may be described as a “second” element in another exemplary embodiment.

[0066] It should be understood that, unless the context explicitly indicates otherwise, the description of a feature or aspect in each exemplary embodiment should generally be considered applicable to other similar features or aspects in other exemplary embodiments.

[0067] Unless the context clearly indicates otherwise, the singular forms “a,” “one,” and “the” are intended to include the plural forms as well, as used herein.

[0068] Figure 1 This is a plan view of a display device according to an exemplary embodiment of the present disclosure. Figure 2 This is a cross-sectional view of a display device according to an exemplary embodiment of the present disclosure when the display device is bent. Figure 3 This is a cross-sectional view of a display device according to an exemplary embodiment of the present disclosure.

[0069] In an exemplary embodiment, the first direction DR1 may intersect with the second direction DR2. Figure 1 In the plan view, the first direction DR1 is defined as the vertical direction, and the second direction DR2 is defined as the horizontal direction. In the following description, when viewed from above, the up arrow on the first direction DR1 indicates the upper side, the down arrow on the first direction DR1 indicates the lower side, the right arrow on the second direction DR2 indicates the right side, and the left arrow on the second direction DR2 indicates the left side. It should be understood that the directions mentioned with respect to the exemplary embodiments are relative directions, and the exemplary embodiments are not limited to the mentioned directions.

[0070] refer to Figures 1 to 3The display device 1 can refer to any electronic device that provides a display screen. The display device 1 may include portable electronic devices such as mobile phones, smartphones, tablet PCs, electronic watches, smartwatches, mobile communication terminals, electronic notebooks, e-books, portable multimedia players (PMPs), navigation devices, game consoles, digital cameras, televisions, laptops, monitors, electronic billboards, Internet of Things devices, etc.

[0071] Display device 1 includes an effective area AAR and an ineffective area NAR. In display device 1, the display area can be defined as an area in which an image is displayed, and the ineffective area can be defined as an area in which no image is displayed. Additionally, the sensing area can be defined as an area in which a sensing input is sensed. The display area and the sensing area can be included within the effective area AAR. The display area and the sensing area can overlap each other. For example, an image can be displayed and a sensing input can be sensed within the effective area AAR. The shape of the effective area AAR can be, for example, a rectangle or a rectangle with rounded corners. In the example shown, the shape of the effective area AAR is a rectangle with rounded corners, and the side of this rectangle extending in the first direction DR1 is longer than the side extending in the second direction DR2. However, it will be understood that this disclosure is not limited thereto. For example, the effective area AAR can have various shapes, such as a rectangular shape, a square shape, other polygonal shapes, a circular shape, an elliptical shape, etc., where the side in the second direction DR2 is longer than the side in the first direction DR1.

[0072] The non-effective region NAR is disposed around the effective region AAR. The non-effective region NAR can be, for example, a border region (e.g., an area with a border). The non-effective region NAR can surround all sides of the effective region AAR (the four sides in the figures). However, it will be understood that this disclosure is not limited thereto. For example, in an exemplary embodiment, the non-effective region NAR may not be disposed near the top of the effective region AAR or near its left or right side.

[0073] In the inactive area NAR, signal lines or drive circuits for applying signals to the active area AAR (display area or sensing area) can be provided. In an exemplary embodiment, the inactive area NAR does not include a display area and does not include a sensing area. Therefore, in an exemplary embodiment, no image is displayed in the inactive area NAR and no sensing input is sensed in the inactive area NAR. In an exemplary embodiment, the inactive area NAR may include a portion of the sensing area, and a sensor component, such as a pressure sensor, may be disposed in that portion. In an exemplary embodiment, the active area AAR may be exactly the same as the display area in which an image is displayed, and the inactive area NAR may be exactly the same as the non-display area in which no image is displayed.

[0074] In an exemplary embodiment, the sensing area in which touch input is sensed may correspond to an effective area AAR, and the non-sensing area in which touch input is not sensed may correspond to an ineffective area NAR. Therefore, multiple sensing conductive layers including multiple sensing electrodes may be provided in the sensing area, and multiple connecting lines connected to the multiple sensing electrodes may be provided in the non-sensing area.

[0075] 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, etc. In the following description, for ease of explanation, an organic light-emitting display panel will be used as an example of the display panel 10. However, this disclosure is not limited thereto.

[0076] The display device 1 may further include a sensing member for sensing a sensing input. The sensing member may be configured to be separate from the display panel 10 and attached to the display panel 10 as a panel or film, or it may be disposed within the display panel 10 as a sensing layer. Although in the following description the sensing member is disposed within the display panel 10 to be included in the display panel 10, it will be understood that this disclosure is not limited thereto. In this document, the sensing member may also be referred to as a touchscreen member.

[0077] The display panel 10 may include a flexible substrate, which includes a flexible polymer material such as polyimide. Therefore, the display panel 10 may be bent, folded, rolled up, or bent.

[0078] The display panel 10 may include a curved region BR. The display panel 10 may be divided into a main region MR located on one side of the curved region BR and an auxiliary region SR located on the other side of the curved region BR.

[0079] The display area of ​​the display panel 10 is located in the main region MR. The display area includes multiple pixels. In an exemplary embodiment, the outer edge portion of the display area in the main region MR, the entire curved region BR, and the entire auxiliary region SR may be non-display areas. However, it will be understood that this disclosure is not limited thereto. The curved region BR and / or the auxiliary region SR may also include display areas.

[0080] When viewed from above, the main region MR may have a shape substantially similar to that of the display device 1. The main region MR may be a flat region located in a plane. However, it will be understood that this disclosure is not limited thereto. At least one of the edges of the main region MR, except for the edge (side) connected to the curved region BR, may be bent to form a bent surface, or may be bent at a right angle.

[0081] A display area may also be disposed at an edge when at least one of the edges of the main region MR, excluding the edge (side) connected to the curved region BR, is bent or curved. However, it will be understood that this disclosure is not limited thereto. The bent or curved edge may be a non-display area where no image is displayed, or both display and non-display areas may be disposed simultaneously.

[0082] The curved region BR connects to a side of the main region MR in the first direction DR1. For example, the curved region BR can connect to the shorter lower side of the main region MR. The width of the curved region BR can be smaller than the width of the main region MR (the width of the shorter side). The portion where the main region MR and the curved region BR intersect can be cut into an L-shape.

[0083] In the curved region BR, the display panel 10 can be bent downwards in the thickness direction (i.e., in the direction away from the display surface) to have a curvature. Although the curved region BR can have a constant radius of curvature, this disclosure is not limited thereto. For example, the curved region BR can have different radii of curvature for different segments. When the display panel 10 is bent at the curved region BR, the surface of the display panel 10 can be flipped. For example, the upward-facing surface of the display panel 10 can be bent such that it faces outwards at the curved region BR and then downwards.

[0084] The auxiliary region SR extends from the curved region BR. In this document, the auxiliary region SR may also be referred to as the sub-region SR. After the display device 1 has been curved, the sub-region SR may extend in a direction parallel to the main region MR. The sub-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 (the width in the second direction DR2) may be, but is not limited to, approximately equal to the width of the curved region BR.

[0085] The sub-region SR can include a first pad region PA1 and a second pad region PA2. For example... Figure 1 As shown in the plan view, the second pad region PA2 is located further away from the curved region BR than the first pad region PA1. The driver chip 70 can be disposed within the first pad region PA1 of the sub-region SR. The driver chip 70 may include, for example, an integrated circuit for driving the display panel 10, and therefore may be referred to as a driver integrated circuit. The integrated circuit may include an integrated circuit for the display and / or an integrated circuit for the sensing unit. The integrated circuit for the display and the integrated circuit for the sensing unit may be configured as separate chips, or may be integrated into a single chip.

[0086] Multiple display signal line pads and multiple sensing signal line pads can be disposed in the second pad area PA2 of the sub-region SR of the display panel 10. A driver board 90 can be connected to the second pad area PA2 of the auxiliary region SR of the display panel 10. The driver board 90 can be, for example, a flexible printed circuit board or a film.

[0087] refer to Figure 3 The display panel 10 may include a display component 20, a sensing component 30 (also referred to as a touch component), a polarizing component 40, a bending protective layer (BPL) 50, and a cover film (Cover IC) 60. The display component 20 may be configured to span the main region MR, the bending region BR, and the auxiliary region SR. For example... Figure 3 As shown in the enlarged view, the display component 20 includes a substrate 101, a circuit layer (e.g., a layer including a plurality of thin-film transistors TR) disposed on the substrate 101, a light-emitting element layer (e.g., an organic emitting layer 122) disposed on the circuit layer, and an encapsulation layer 116 disposed on the light-emitting element layer (see Figure 122). Figure 4 The light-emitting element layer may include multiple light-emitting elements for displaying images. The display panel 10 may also include a first electrode 121 disposed below the organic emitting layer 122 and a second electrode 123 disposed on the organic emitting layer 122 (see...). Figure 4 The first electrode 121, the organic emitting layer 122, and the second electrode 123 can form a light-emitting element. The light-emitting element can be disposed in each of the pixels.

[0088] When viewed from a plan view, the shape of the display component 20 can be substantially the same as the shape of the display panel 10 described above. For example, when viewed from a plan view, the display component 20 can have a shape that is substantially the same as the shape of the main region MR, the curved region BR, and the auxiliary region SR.

[0089] The sensing member 30 may be disposed on the display member 20. The sensing member 30 can detect touch input. The sensing member 30 may be configured to span the main region MR, the curved region BR, and the auxiliary region SR. That is, the sensing member 30 may overlap with the main region MR, the auxiliary region SR, and the curved region BR. The sensing member 30 may be formed directly on the display member 20. As described later, the sensing member 30 may include, for example, a first sensing insulating layer, a first sensing conductive layer disposed on the first sensing insulating layer, a second sensing insulating layer disposed on the first sensing conductive layer, and a second sensing conductive layer disposed on the second sensing insulating layer.

[0090] The second sensing conductive layer may be the top layer of the sensing member 30. The second sensing conductive layer and the second sensing insulating layer of the sensing member 30 may be exposed to the outside. According to an exemplary embodiment, the thickness of the display device 1 can be reduced by disposing the second sensing conductive layer on top of the sensing member 30 and removing the protective layer (such as an organic layer) covering the second sensing conductive layer.

[0091] However, since the second sensing conductive layer is exposed, external air or moisture can penetrate into it, potentially causing corrosion. To prevent this, in the display panel 10 according to an exemplary embodiment, a polarizing member 40 is provided in the main region MR, a bending protective layer 50 is provided in the bending region BR, and a cover film 60 is provided in the auxiliary region SR, thereby covering and protecting the exposed second sensing conductive layer. The polarizing member 40, the bending protective layer 50, and the cover film 60 can be disposed on the sensing member 30.

[0092] When viewed from a plan view, the shape of the sensing element 30 can be substantially the same as the shape of the display element 20. For example, when viewed from a plan view, the sensing element 30 can have a shape that is substantially the same as the shape of the main region MR, the curved region BR, and the auxiliary region SR.

[0093] like Figure 3 As shown, in an exemplary embodiment, the polarizing member 40 substantially overlaps with the main region MR in the thickness direction and is not disposed in the bending region BR. The bending protective layer 50 may completely overlap with the bending region BR and may extend to a portion of the main region MR and the auxiliary region SR adjacent to the bending region BR. The side surface of the polarizing member 40 may contact (e.g., directly contact) the side surface of the bending protective layer 50. For example, in an exemplary embodiment, no gap is formed between the side surface of the polarizing member 40 and the side surface of the bending protective layer 50, and the boundary between the side surface of the bending protective layer 50 and the side surface of the polarizing member 40 may be located in the main region MR.

[0094] In an exemplary embodiment, the cover film 60 substantially overlaps with the auxiliary region SR in the thickness direction and is not disposed in the bending region BR. The other side surface of the bending protective layer 50 may contact (e.g., directly contact) the side surface of the cover film 60. For example, in an exemplary embodiment, there is no gap between the other side surface of the bending protective layer 50 and the side surface of the cover film 60. The boundary between the other side surface of the bending protective layer 50 and the side surface of the cover film 60 may be located in the auxiliary region SR.

[0095] Refer again Figure 1 When viewed in a plan view, the shape of the polarizing member 40 can be substantially the same as the shape of the portion of the sensing member 30 disposed within the main region MR as described above. In an exemplary embodiment, when viewed in a plan view, the polarizing member 40 can be smaller than the sensing member 30, such that a portion of the edge of the portion of the sensing member 30 falling within the main region MR can be exposed.

[0096] When viewed in plan view, the shape of the bending protective layer 50 may be substantially the same as the shape of the portion of the sensing member 30 that falls within the bending region BR, as described above. When viewed in plan view, the shape of the bending protective layer 50 may be substantially rectangular. In an exemplary embodiment, when viewed in plan view, the bending protective layer 50 may be smaller than the sensing member 30. For example, the width of the bending protective layer 50 in the second direction DR2 may be smaller than the width of the sensing member 30 in the second direction DR2.

[0097] When viewed in plan view, the shape of the cover film 60 may be substantially the same as the shape of the portion of the sensing member 30 disposed within the auxiliary region SR as described above. When viewed in plan view, the shape of the cover film 60 may be substantially rectangular. In an exemplary embodiment, when viewed in plan view, the cover film 60 may be smaller than the sensing member 30. For example, the width of the cover film 60 in the second direction DR2 may be smaller than the width of the sensing member 30 in the second direction DR2.

[0160] The bending protective layer 50 may be made of a material including an organic insulating material. The organic insulating material may be, but is not limited to, organic resins.

[0161] As described above, the side surface of the polarizing member 40 can contact (e.g., directly contact) the side surface of the bending protective layer 50. For example, in an exemplary embodiment, no gap is formed between the side surface of the polarizing member 40 and the side surface of the bending protective layer 50. Reference will be made below.

[0167] According to an exemplary embodiment of the present disclosure, as described above, the thickness of the display device 1 can be reduced by disposing the second sensing conductive layer TCL2 on top of the sensing member 30 and removing the protective layer (such as an organic layer) covering the second sensing conductive layer TCL2.

[0168] Furthermore, as previously described, in the comparative example, when the second sensing conductive layer TCL2 is exposed, external air or moisture can penetrate into it, which may corrode and damage it.

[0169] However, in order to cover and protect the second sensing conductive layer TCL2, it is desirable that no gap be formed between the polarizing member 40 and the bending protective layer 50. For this purpose, the bending protective layer 50 can be formed after attaching the polarizing member 40 by depositing the constituent material of the bending protective layer 50 onto a portion of the upper surface of the polarizing member 40.

[0171] refer to Figure 11 After attaching the polarizing member 40, an organic material layer 50a is formed in the curved region BR, a portion of the main region MR, and a portion of the auxiliary region SR. The organic material layer 50a can be formed by, for example, slot coating or spin coating. The organic material layer 50a is formed such that it contacts the side surface of the polarizing adhesive layer 410 of the polarizing member 40, the side surface of the polarizing layer 430, and the upper and side surfaces of the first sensing connection electrode TCE1 of the second sensing conductive layer TCL2. During the process of applying the organic material 50b to the side surface of the polarizing member 40, a portion of the organic material 50b may also be applied to the polarizing member 40.

[0172] refer to Figure 12The isolation film 450 disposed on the polarizing member 40 is peeled off and removed. During the peeling and removal of the isolation film 450, the organic material 50b on the polarizing member 40 is removed together with the isolation film 450, and therefore, after the bending protective layer 50 is formed, the bending protective layer 50 and its constituent materials do not remain on the upper surface of the polarizing member 40. Furthermore, as described above, since the bending protective layer 50 is formed to contact (e.g., in direct contact) the entire side surface of the polarizing member 40, there is no gap between the bending protective layer 50 and the polarizing member 40. Therefore, the second sensing conductive layer TCL2 is not exposed to external air or moisture, and thus, corrosion of the second sensing conductive layer TCL2 can be prevented.

[0173] Hereinafter, a display device according to an exemplary embodiment of the present disclosure will be described. In the following description, the same or similar elements will be indicated by the same or similar reference numerals. For ease of explanation, further descriptions of elements that are the same or similar to those previously described may be omitted or only briefly described.

[0174] Figure 13 This is a cross-sectional view of a display panel according to an exemplary embodiment of the present disclosure.

[0175] Besides the fact that the side surfaces of the polarizing member 40_1 and the cover film 60_1 are non-uniform in the thickness direction, and the side surfaces of the curved protective layer 50_1 that contact these side surfaces are also non-uniform in the thickness direction, according to... Figure 13 The display panel 11 of the exemplary embodiment shown is substantially the same as the display panel 10 according to the exemplary embodiment described above.

[0176] For example, the side surfaces of the polarizing member 40_1 and the cover film 60_1 have asymmetrical shapes in the thickness direction, and the side surface of the bent protective layer 50_1 that contacts these side surfaces may also have asymmetrical shapes in the thickness direction. The side surfaces of the polarizing member 40_1 and the cover film 60_1 may be inclined at acute angles. For example, the side surfaces of the polarizing adhesive layer 410_1 and the polarizing layer 430_1 of the polarizing member 40_1 may be inclined in the thickness direction. The side surface of the bent protective layer 50_1 that contacts the side surfaces of the polarizing member 40_1 and the cover film 60_1 may be inclined at obtuse angles. The sum of the inclination angle of the side surface of the polarizing member 40_1 and the inclination angle of the side surface of the bent protective layer 50_1 may be approximately 180 degrees.

[0177] The side surfaces of the polarizing member 40_1 and the bending protective layer 50_1 can partially overlap each other in the thickness direction. For example, since the side surfaces of the polarizing member 40_1 and the bending protective layer 50_1 partially overlap each other, the possibility of a gap forming between the polarizing member 40_1 and the bending protective layer 50_1 can be reduced. Furthermore, even if a certain gap forms between them, the penetration of external air or moisture can be reduced because these side surfaces overlap each other.

[0178] Figure 14 This is a cross-sectional view of a display panel according to an exemplary embodiment of the present disclosure.

[0179] Except for the fact that the side surface of the polarization layer 430_1 of the polarization member 40_2 is uneven in the thickness direction, while the side surface of the polarization adhesive layer 410 is uniform in the thickness direction, according to... Figure 14 The display panel 12 of the exemplary embodiment shown is with Figure 13 The display panel 11 shown is substantially the same. For example, the side surface of the polarizing layer 430_1 may be inclined in the thickness direction, and the side surface of the polarizing adhesive layer 410 may be substantially straight in the thickness direction. The side surface of the bending protective layer 50_2 may contact the side surfaces of the polarizing layer 430_1 and the polarizing adhesive layer 410, and the side surface of the bending protective layer 50_2 may contact the side surface of the cover film 60_1.

[0180] For ease of explanation, the above references will not be described again. Figure 13 and Figure 7 The components that have already been described.

[0181] Figure 15 This is a cross-sectional view of a display panel according to an exemplary embodiment of the present disclosure.

[0182] Except that the polarizing layer 430_2 of the polarizing member 40_3 is positioned closer to the interior than the polarizing adhesive layer 410 in the direction toward the main region MR, so that the upper surface of the polarizing adhesive layer 410 is partially exposed, and the bending protective layer 50_3 covers the exposed upper surface of the polarizing adhesive layer 410, according to... Figure 15 The display panel 13 of the exemplary embodiment shown is with Figure 14 The display panel 12 shown is substantially the same. For example, the distance between the polarizing layer 430_2 and the curved region BR can be greater than the distance between the polarizing adhesive layer 410 and the curved region BR.

[0183] For ease of explanation, the above will not be described again. Figure 14 and Figure 7 The components that have already been described.

[0184] Figure 16This is a cross-sectional view of a display panel according to an exemplary embodiment of the present disclosure.

[0185] In addition to the boundary between polarizing member 40_4 and bending protective layer 50_4 being aligned with the boundary between main region MR and bending region BR, and the boundary between bending protective layer 50_4 and cover film 60_2 being aligned with the boundary between auxiliary region SR and bending region BR, according to... Figure 16 The display panel 14 of the exemplary embodiment shown is substantially the same as the display panel 10 described above. For example, the side surfaces of the polarizing adhesive layer 410_2 and the side surfaces of the polarizing layer 430_3 can be aligned at the boundary between the main region MR and the curved region BR.

[0186] For ease of explanation, the above references will not be described again. Figure 7 The components that have already been described.

[0187] The method for manufacturing the display device 1 will be described below. In the following description, the same or similar elements will be indicated by the same or similar reference numerals, and for ease of explanation, redundant descriptions will be omitted or only briefly described.

[0188] Figure 17 This is a flowchart illustrating a method for manufacturing a display device according to an exemplary embodiment of the present disclosure. Figures 18 to 21 This is a cross-sectional view illustrating the process steps of a method for manufacturing a display device according to an exemplary embodiment of the present disclosure.

[0189] refer to Figures 17 to 21 The display panel 10 can be referred to as the target panel. After the components are stacked on the sub-substrate 105, the target panel can be cut into units by, for example, a unit cutting process.

[0190] refer to Figure 17 and Figure 18 A sub-substrate 105 is disposed below the substrate 101. The sub-substrate 105 may be disposed below the substrate 101 to manufacture a target panel including the substrate 101. The sub-substrate 105 may include a rigid material such as glass.

[0191] refer to Figure 17 and Figure 19 In the sensing component 30 (see Figure 3 A protective film 80 is disposed on the substrate 105 (operation S10). The protective film 80 may include a film layer 830 and an adhesive layer 810 disposed on the film layer 830. The protective film 80 may be configured to span the main region MR, the bending region BR, and the auxiliary region SR. As described later, the sub-substrate 105 will be separated. Then, when forming a structure including a support plate, the protective film 80 may support the target panel, the support plate comprising, for example, a rigid or semi-rigid material supporting the target panel.

[0192] The adhesive layer 810 of the protective film 80 can be configured to adhere to the second sensing conductive layer TCL2 (see...). Figure 5 Contact. Furthermore, the adhesive layer 810 may be configured to directly contact the second sensing insulating layer 330, which is not covered by the second sensing conductive layer TCL2. In an exemplary embodiment, the adhesive layer 810 may be an adhesive comprising inorganic materials. For example, the adhesive layer 810 may be an adhesive comprising silicone-based inorganic materials. Because the adhesive layer 810 is made of an adhesive comprising inorganic materials, it can be easily peeled off from the second sensing conductive layer TCL2 and the second sensing insulating layer 330 during the process of peeling off the protective film 80, as will be described later.

[0193] Subsequently, reference Figure 17 and Figure 20 As described above, the sub-substrate 105 is separated from the substrate 101. After the bonding force between the substrate 101 and the sub-substrate 105 is weakened by irradiating the surface of the substrate 101 with a laser using, for example, a laser device, to promote separation, a process for separating the sub-substrate 105 is performed.

[0194] Subsequently, reference Figure 17 and Figure 21 As described above, the protective film 80 is peeled off from one surface of the sensing member 30 (operation S20). For example, the protective film 80 can be peeled off from the second sensing conductive layer TCL2 and the second sensing insulating layer 330 not covered by the second sensing conductive layer TCL2. As described above, because the adhesive layer 810 is made of an adhesive containing inorganic materials, the process of peeling off the protective film 80 can be easily performed.

[0195] Subsequently, reference Figure 4 and Figure 17 The polarizing member 40 is attached to the surface of the sensing member 30 where the protective film 80 has been peeled off (operation S30). The polarizing adhesive layer 410 of the polarizing member 40 is configured to contact the second sensing conductive layer TCL2 of the sensing member 30 and the second sensing insulating layer 330 not covered by the second sensing conductive layer TCL2.

[0196] Figure 22 This is a cross-sectional view of a display device according to an exemplary embodiment of the present disclosure.

[0197] Figure 23 is a cross-sectional view of the main region of a display device according to an exemplary embodiment of the present disclosure.

[0198] 24 is a plan view showing the layout of the display components and sensing components of a display device according to an exemplary embodiment of the present disclosure. Figure 25 yes Figure 24 An enlarged plan view of a portion of the display device shown in the figure. Figure 26 This is a view showing the layout of signal lines arranged in the main region, the curved region, and the auxiliary region according to an exemplary embodiment of the present disclosure. Figure 27 It is along Figure 26 A sectional view taken from line XXVII-XXVII'. Figure 28 It is along Figure 26 A sectional view taken from line XXVIII-XXVIII'. Figure 29 It is along Figure 26 A sectional view taken from the line XXIX–XXIX'.

[0199] Except for the sensing component 30_1, which does not include the second sensing insulating layer 330 and the second sensing conductive layer TCL2, according to... Figures 22 to 29 The sensing element 30_1 (also called the touch element) of the exemplary embodiment shown is substantially the same as the sensing element 30 described above.

[0200] refer to Figure 23 The polarization adhesive layer 410 of the polarization member 40 can be directly disposed on the upper surface of the first sensing conductive layer TCL1_1. For example, the polarization adhesive layer 410 can be in direct contact with the first sensing conductive layer TCL1_1. The polarization adhesive layer 410 can also be in contact with the upper surface of the first sensing insulating layer 310 that is not covered by the first sensing conductive layer TCL1_1.

[0201] refer to Figure 24 and Figure 25 The sensing member 30_1 according to an exemplary embodiment of the present disclosure may include a plurality of sensing line portions SPL3. The sensing line portions SPL3 may be arranged in a matrix. For example, the sensing line portions SPL3 may be arranged along a first direction DR1 and a second direction DR2. The sensing line portions SPL3 may be formed in a rectangular shape, but the present disclosure is not limited thereto. In the exemplary embodiment, the sensing line portions SPL3 may have various shapes, such as polygonal shapes and circular shapes. Furthermore, in the exemplary embodiment, the sensing line portions SPL3 may have two or more shapes. For example, some of the sensing line portions SPL3 may have a rectangular shape, and others may have a circular shape. Furthermore, in the exemplary embodiment, the sensing line portions SPL3 may have different areas. For example, when a hole for inserting a camera, etc., is formed in the display device 1, the sensing line portions SPL3 around the hole may have a shape that removes a portion of the sensing line portion SPL3 along the shape of the hole.

[0202] The sensing line portions SPL3 can be formed in an island shape and spaced apart from each other. In this document, the shape, size, and / or arrangement of the sensing line portions SPL3 are not specifically limited. The sensing line portions SPL3 can receive drive signals for detecting sensing operations. Additionally, the sensing line portions SPL3 can output sensing signals for detecting sensing operations via a fourth signal line SL4.

[0203] The sensing line portion SPL3 may overlap with at least one electrode disposed in the display member 20. For example, when the display member 20 is an organic light-emitting diode display panel, the sensing line portion SPL3 may overlap with the cathode electrode of the display member 20.

[0204] The sensing line portion SPL3 can form a first capacitance with an electrode disposed in the display member 20. When a sensing operation is performed by, for example, a user's finger passing through at least one of the sensing line portions SPL3, a second capacitance is generated between the finger and the sensing line portion SPL3, and the first capacitance changes due to the second capacitance. The change in the first capacitance is transmitted to the sensing detection unit via a fourth signal line SL4 connected to the sensing line portion SPL3 that performed the sensing operation. The sensing detection unit can detect the sensing position based on the fourth signal line SL4 receiving the change in the first capacitance.

[0205] The sensing line portion SPL3 and the fourth signal line SL4 may have a grid structure for transmitting light emitted from the display area of ​​the display member 20. For example, the sensing line portion SPL3 and the fourth signal line SL4 may include a plurality of grid holes MH, through which the first sensing insulating layer 310 is partially exposed. The grid holes MH of the sensing line portion SPL3 and the fourth signal line SL4 may overlap with the emitting area of ​​the display member 20 in the thickness direction. Furthermore, the area of ​​the grid holes MH may be larger than the area of ​​the emitting area of ​​the display member 20. Since the grid holes MH are formed in the sensing line portion SPL3 and the fourth signal line SL4, even if the sensing line portion SPL3 and the fourth signal line SL4 are disposed in the display area of ​​the display member 20, light emitted from the display area of ​​the display member 20 can be transmitted through the sensing line portion SPL3 and the fourth signal line SL4 and emitted.

[0206] Besides the first sensing insulating layer 310 exposed by the first sensing conductive layer TCL1_1 of the sensing component 30_1 and the first sensing conductive layer TCL1_1 being able to directly contact the polarization adhesive layer 410 of the polarization component 40 thereon, according to... Figures 26 to 29 The sensing element 30_1 of the exemplary embodiment shown is substantially the same as the sensing element 30 described above.

[0207] For example, refer to Figure 26The first signal line SL1 may include the source connection electrode SCE of the second conductive layer DCL2 and the third sensing connection electrode TCE3_1 of the first sensing conductive layer TCL1_1. The third sensing connection electrode TCE3_1 can be electrically connected to the third sensing connection electrode TCE3_1 through the fifth contact hole CNT5_1. The fourth signal line SL4 may include the source connection electrode SCE of the second conductive layer DCL2, the first sensing connection electrode TCE1_1 of the first sensing conductive layer TCL1_1, and the third sensing connection electrode TCE3_1. The source connection electrode SCE of the fourth signal line SL4 is connected to the first sensing connection electrode TCE1_1 and the third sensing connection electrode TCE3_1 through the first contact hole CNT1_1 and the second contact hole CNT2_1, respectively.

[0208] The first contact hole CNT1_1 can be located in the main region MR, and the second contact hole CNT2_1 and the fifth contact hole CNT5_1 can be located in the auxiliary region SR.

[0209] refer to Figure 27 One side surface of the polarization layer 430 of the polarization member 40 and one side surface of the polarization adhesive layer 410 can be aligned in the thickness direction. The polarization member 40 can substantially cover and protect the upper surface of the first sensing connection electrode TCE1_1. The polarization member 40 can expose a portion of the upper surface of the first sensing connection electrode TCE1_1.

[0210] The cover film 60 can substantially cover the upper surface of the third sensing connection electrode TCE3_1 to protect the third sensing connection electrode TCE3_1. The cover film 60 can also expose a portion of the upper surface of the third sensing connection electrode TCE3_1.

[0211] The cover film 60 can cover and protect the first sensing conductive layer TCL1_1 exposed in the auxiliary region SR.

[0212] The first contact hole CNT1_1 and the second contact hole CNT2_1 can penetrate the encapsulation layer 116 (only the first contact hole CNT1_1 penetrates the encapsulation layer 116), the dam 115, and the protective layer 114 below the first sensing conductive layer TCL1_1, and can be electrically connected to the source connection electrode SCE of the second conductive layer DCL2.

[0213] The bending protective layer 50 can contact the exposed side surfaces of the first sensing connection electrode TCE1_1 and the third sensing connection electrode TCE3_1 of the first sensing conductive layer TCL1_1. Furthermore, the bending protective layer 50 can be disposed on the exposed upper surfaces of the first sensing connection electrode TCE1_1 and the third sensing connection electrode TCE3_1 to protect the upper surfaces of the first sensing connection electrode TCE1_1 and the third sensing connection electrode TCE3_1 from external air or moisture.

[0214] refer to Figure 28 The source connection electrode SCE can be electrically connected to the third sensing connection electrode TCE3_1 through the fifth contact hole CNT5_1 in the auxiliary region SR. The fifth contact hole CNT5_1 can penetrate the embankment 115 and the protective layer 114 below the first sensing conductive layer TCL1_1, and can be electrically connected to the source connection electrode SCE of the second conductive layer DCL2.

[0215] refer to Figure 29 The polarization adhesive layer 410 of the polarization member 40 can cover the upper and side surfaces of the first sensing connection electrodes TCE1_1 that are spaced apart from each other. For example, the polarization adhesive layer 410 can be in contact with the upper and side surfaces of the first sensing connection electrodes TCE1_1.

[0216] As described above, according to an exemplary embodiment of the present disclosure, the thickness of the display device 1 can be reduced by disposing a first sensing conductive layer TCL1_1 on top of the sensing member 30_1 and removing a protective layer (such as an organic layer) covering the first sensing conductive layer TCL1_1.

[0217] Figure 30 This is a cross-sectional view of a display panel according to an exemplary embodiment of the present disclosure.

[0218] In addition to color filters 161_R, 161_G, and 161_B, and a light-blocking pattern BM replacing the polarizing member 40 and being disposed in the main region MR (and overlapping with the main region MR), according to... Figure 30 The display panel 10_1 of the exemplary embodiment shown is substantially the same as the display panel 10 described above.

[0219] For example, the light-blocking pattern BM can be disposed on and in direct contact with the second sensing conductive layer TCL2. The sensing electrodes and sensing bridging electrodes of the second sensing conductive layer TCL2 in the main region MR can be in contact with the light-blocking pattern BM. The light-blocking pattern BM can overlap with the embankment 115 below the light-blocking pattern BM in the thickness direction. The light-blocking pattern BM can be, for example, a black matrix and can include a photosensitive organic material.

[0220] Color filters 161_R, 161_G, and 161_B can be disposed on the light-blocking pattern BM and the second sensing conductive layer TCL2 in each pixel. Color filters 161_R, 161_G, and 161_B may include a red color filter 161_R that transmits red light and blocks green and blue light, a green color filter 161_G that transmits green light and blocks red and blue light, and a blue color filter 161_B that transmits blue light and blocks red and green light. Color filters 161_R, 161_G, and 161_B may include a photosensitive organic material. The light-blocking pattern BM may expose the upper surface of the second sensing insulating layer 330, and color filters 161_R, 161_G, and 161_B may be in direct contact with the exposed upper surface of the second sensing insulating layer 330.

[0221] As described above, the plurality of sensing electrodes and sensing bridging electrodes of the second sensing conductive layer TCL2 can be disposed separately from each other. Because the sensing electrodes and sensing bridging electrodes are spaced apart from each other, the upper surface of the second sensing insulating layer 330 can be partially exposed. Color filters 161_R, 161_G, and 161_B can contact the exposed upper surface of the second sensing insulating layer 330.

[0222] An organic planarization layer 180 can be disposed on color filters 161_R, 161_G, and 161_B. Color filters 161_R, 161_G, and 161_B can have the following characteristics: Figure 30 The horizontal difference is shown in the figure. The organic planarization layer 180 can provide a flat surface on this horizontal difference. The organic planarization layer 180 may include organic materials.

[0223] According to such Figure 30 The difference between the display panel 10_1 of the exemplary embodiment shown and the display panel 10 is that the polarizing member 40 is removed in the main region MR, but a light-blocking pattern BM is provided in the main region MR, so that the sensing electrodes and sensing bridge electrodes of the exposed second sensing conductive layer TCL2 located under the light-blocking pattern BM can be covered and protected.

[0224] Although this disclosure has been specifically shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of this disclosure as defined by the appended claims.
