[0036] Now will be referred to in detail embodiments, examples of embodiments are shown in the accompanying drawings, wherein the same reference numerals may always indicate the same elements. In this regard, embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Therefore, embodiments are described below with reference to the accompanying drawings only to illustrate various aspects of this description. However, the present disclosure may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0037] It will be understood that when a layer, a region, or a component is referred to as being “formed on” another layer, region, or component, the layer, region, or component may be directly or indirectly formed on the other layer, region, or component.

[0038] The sizes of elements in the drawings may be exaggerated for convenience of explanation.

[0039] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Like reference numerals may refer to like elements throughout the drawings.

[0040] Figure 1 is a schematic plan view of a display device 10 according to the embodiment. Figure 6 yes Figure 1 Schematic plan view of portion B of FIG.

[0041] Reference Figure 1According to an embodiment, the display device 10 includes a display panel 100 and an input detection unit 200 disposed above the display panel 100. In addition, the display device 10 includes a recess T having a side recessed inward from an edge of the display device 10. In other words, the display panel 100 and the input detection unit 200 have sides recessed in accordance with the side of the recess T of the display device 10. Components that extend the function of the display device 10, such as a camera module, a speaker, a sensor, etc., may be disposed in the recess T.

[0042] According to an embodiment, the display panel 100 displays an image. The input detection unit 200 includes first and second detection electrodes 210 and 230 that may detect contact with an external touch input unit such as a user's hand or a pen, thereby generating an input signal.

[0043] According to an embodiment, the first sensing electrodes 210 are connected to each other in the first direction D1 to form a plurality of first sensing electrode arrays 210-1 and 210-2 extending parallel to each other in the first direction D1. In addition, the plurality of first sensing electrode arrays 210-1 and 210-2 are spaced apart from each other in a second direction D2 perpendicular to the first direction D1.

[0044] According to an embodiment, the first detection electrodes 210 in the region near the recess T are prevented from being continuously arranged in the first direction D1 by the recess T. For example, when the recess T extends to the position of the first detection electrode array 210-1, the pairs of first detection electrodes 210 positioned at both sides of the recess T are not directly connected to each other. Therefore, in an embodiment, Figure 6 The connection wiring 250 shown in FIG. 2 bypassing the recess T is used to electrically connect the paired first detection electrodes 210 to each other.

[0045] According to an embodiment, it is possible to adjust Figure 6 The width of the connection wiring 250 is set so that the resistance value of the first detection electrode array 210-1 including the pairs of first detection electrodes 210 electrically connected to each other via the connection wiring 250 is the same as the resistance value of the other first detection electrode array 210-2 in which the first detection electrodes 210 are continuously arranged.

[0046] According to the embodiment, the second detection electrodes 230 are disposed between the first detection electrodes 210 and connected to each other in the second direction D2, and extend parallel to each other in the second direction D2. Therefore, since the continuous connection of the second detection electrodes 230 is not blocked by the recess T, bypass wiring for electrically connecting the second detection electrodes 230 to each other is not required.

[0047] According to an embodiment, Figure 1An example is shown in which the first detection electrode 210 and the second detection electrode 230 have a rhombus shape. However, the first detection electrode 210 and the second detection electrode 230 are not limited thereto and may have various shapes.

[0048] Figure 2 yes Figure 1 1 is a schematic plan view of an example of a display panel 100 of a display device 10 . Figure 3 It is taken along line I-I' and line II-II' Figure 2 1 is a schematic cross-sectional view of an example of a display panel 100 .

[0049] Reference Figure 2 and Figure 3 According to an embodiment, the display panel 100 has Figure 1 The recess T1 is consistent with the recess T of the display panel 100, and the recess T1 has a side that is recessed inward from the edge of the display panel 100. The display panel 100 has a display area DA that displays an image and a peripheral area PA that surrounds the display area DA and is disposed outside the display area DA. The peripheral area PA includes a pad area PADA to which various electronic devices or a printed circuit board are electrically attached, and voltage lines 410 and 420 are disposed in the peripheral area PA. The side of the display panel 100 having the recess T1 is opposite to the side of the pad area PADA.

[0050] According to an embodiment, Figure 2 1 is a plan view of the substrate 101 when the display panel 100 is manufactured. In the completed display panel 100 or an electronic device such as a smart phone including the display panel 100, a portion of the substrate 101 is bent to minimize the area of ​​the peripheral area PA recognized by the user. For example, the substrate 101 is bent between the pad area PADA and the display area DA so that at least a portion of the pad area PADA overlaps with the display area DA. The bending direction is determined so that the pad area PADA does not cover the display area DA but is positioned behind the display area DA. Therefore, the user can recognize that the display area DA occupies the display area DA. Figure 1 A larger portion of the display device 10.

[0051] In addition, according to the embodiment, the left and right edges of the display area DA are bent to protrude outward. Figure 1 When the display device 10 is Figure 1 The side edges of the display device 10 will not include a frame, thereby having the effect of expanding the display area DA.

[0052] Figure 3 yes Figure 2 A schematic cross-sectional view of a portion of a display panel 100 is shown. Figure 3In the embodiment, the display panel 100 is an organic light emitting display panel including an organic light emitting device 310. However, the embodiments of the present disclosure are not limited thereto. The display panel 100 may include other types of display devices, for example, a liquid crystal device.

[0053] According to an embodiment, the substrate 101 is made of, for example, silicon dioxide (SiO 2 ) as a main component of transparent glass. However, the substrate 101 is not limited thereto and may be formed of plastic. The plastic includes a polymer resin such as polyethersulfone, (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC) or cellulose acetate propionate (CAP). Alternatively, for example, the substrate 101 may be variously modified to include metal or the like.

[0054] According to an embodiment, a thin film transistor TFT is disposed in a display area DA of a substrate 101. In addition to the thin film transistor TFT, an organic light emitting device 310 electrically connected to the thin film transistor TFT is disposed in the display area DA. Specifically, a pixel electrode 311 of the organic light emitting device 310 is connected to the thin film transistor TFT. A thin film transistor is also disposed in the peripheral area PA of the substrate 101. For example, the thin film transistor in the peripheral area PA may be a part of a circuit that controls an electrical signal transmitted to the display area DA.

[0055] According to an embodiment, the thin film transistor TFT includes a semiconductor layer 111, a gate electrode 113, a source electrode 115a, and a drain electrode 115b. The semiconductor layer 111 includes amorphous silicon, polycrystalline silicon, or an organic semiconductor material. A buffer layer 110 formed of an inorganic material such as silicon oxide, silicon nitride, or silicon oxynitride is disposed on the substrate 101 to flatten the surface of the substrate 101 or prevent impurities from penetrating into the semiconductor layer 111. The semiconductor layer 111 is disposed on the buffer layer 110.

[0056] According to an embodiment, the gate electrode 113 is disposed on the semiconductor layer 111. According to a signal received through the gate electrode 113, the source electrode 115a is electrically connected to the drain electrode 115b. For example, the gate electrode 113 includes one or more of aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), lithium (Li), calcium (Ca), molybdenum (Mo), titanium (Ti), tungsten (W) and copper (Cu). The gate electrode 113 may have a single-layer structure or a multi-layer structure. In order to insulate the semiconductor layer 111 from the gate electrode 113, a gate insulating layer 121 formed of an inorganic material such as silicon oxide, silicon nitride or silicon oxynitride is disposed between the semiconductor layer 111 and the gate electrode 113.

[0057] According to an embodiment, an interlayer insulating layer 131 is disposed on the gate electrode 113. The interlayer insulating layer 131 is formed of an inorganic material such as silicon oxide, silicon nitride, or silicon oxynitride, and may have a single layer structure or a multilayer structure.

[0058] According to an embodiment, the source electrode 115a and the drain electrode 115b are disposed on the interlayer insulating layer 131. Both the source electrode 115a and the drain electrode 115b are electrically connected to the semiconductor layer 111 via contact holes formed in the interlayer insulating layer 131 and the gate insulating layer 121. According to desired conductivity, etc., for example, the source electrode 115a and the drain electrode 115b include one or more of Al, Pt, Pd, Ag, Mg, Au, Ni, Nd, Ir, Cr, Li, Ca, Mo, Ti, W, and Cu. The source electrode 115a and the drain electrode 115b may have a single-layer structure or a multi-layer structure.

[0059] According to an embodiment, in order to protect the thin film transistor TFT having such a structure, a protective layer covering the thin film transistor TFT is provided. The protective layer is formed of an inorganic material such as silicon oxide, silicon nitride or silicon oxynitride. The protective layer may include a single layer or multiple layers.

[0060] According to an embodiment, the planarization layer 140 is disposed above the protective layer. Figure 3 As shown in , when the organic light emitting device 310 is disposed above the thin film transistor TFT, the planarization layer 140 planarizes the entire upper surface of the protective layer covering the thin film transistor TFT. For example, the planarization layer 140 includes an organic material such as acryl, benzocyclobutene (BCB) or hexamethyldisiloxane (HMDSO). Figure 3 The planarization layer 140 is shown to have a single layer. However, the embodiment is not limited thereto, and the planarization layer 140 may include a plurality of layers.

[0061] In the current embodiment, the display panel 100 may include both the protection layer and the planarization layer 140 , or only the planarization layer 140 as needed.

[0062] According to an embodiment, in the display area DA of the substrate 101 , the pixel electrode 311 , the intermediate layer 315 including the light emitting layer, and the opposing electrode 313 are disposed on the planarization layer 140 .

[0063] According to an embodiment, an opening exposing at least one of the source electrode 115a and the drain electrode 115b is formed in the planarization layer 140. The pixel electrode 311 is disposed on the planarization layer 140 and contacts the source electrode 115a or the drain electrode 115b via the opening to be electrically connected to the thin film transistor TFT. The pixel electrode 311 may include a (semi) transparent electrode or a reflective electrode. When the pixel electrode 311 is a (semi) transparent electrode, the pixel electrode 311 includes indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In 2 O 3 ), indium gallium oxide (IGO) and aluminum zinc oxide (AZO). When the pixel electrode 311 is a reflective electrode, the pixel electrode 311 has a reflective layer formed of at least one of Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr and their compounds, and a reflective layer formed of ITO, IZO, ZnO, In 2 O 3 , IGO or AZO. However, the embodiments of the present disclosure are not limited thereto, and the pixel electrode 311 may include various other materials. The pixel electrode 311 may also have a single-layer structure or a multi-layer structure.

[0064] According to an embodiment, the pixel defining layer 150 is disposed on the planarization layer 140. The pixel defining layer 150 has an opening corresponding to each sub-pixel, that is, an opening that exposes at least the central portion of the pixel electrode 311 forming the pixel. Figure 3 In the case shown in FIG. 1 , the pixel defining layer 150 prevents arcing etc. from being generated at the edge of the pixel electrode 311 by increasing the distance between the edge of the pixel electrode 311 and the edge of the counter electrode 313 above the pixel electrode 311. For example, the pixel defining layer 150 includes an organic material such as PI or HMDSO etc.

[0065] According to an embodiment, the intermediate layer 315 of the organic light emitting device 310 includes a low molecular weight material or a polymer material. When the intermediate layer 315 includes a low molecular weight material, the intermediate layer 315 has a stacked structure including a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML), an electron transport layer (ETL), or an electron injection layer (EIL), and includes a copper phthalocyanine (CuPc), N, N'-di (naphthalene-1-yl) -N, N'-diphenyl-benzidine (NPB) or tris-8-hydroxyquinoline aluminum (Alq 3 ) etc. These layers can be formed by a vacuum deposition method.

[0066] According to an embodiment, when the intermediate layer 315 includes a polymer material, the intermediate layer 315 has a structure including, for example, HTL and EML. The HTL includes poly-(2,4)-ethylene-dihydroxythiophene (PEDOT), and the EML includes a polymer material such as polyphenylene vinylene (PPV) or polyfluorene. The intermediate layer 315 can be formed by a screen printing or inkjet printing method, a laser induced thermal imaging (LITI) method, etc.

[0067] However, according to embodiments, the intermediate layer 315 is not limited thereto and may have various other structures.

[0068] According to an embodiment, the counter electrode 313 is disposed above the display area DA. Figure 3 As shown in FIG. 1 , the counter electrode 313 covers the display area DA. That is, the counter electrode 313 is formed as one body with respect to the plurality of organic light-emitting devices 310 and corresponds to the plurality of pixel electrodes 311. The counter electrode 313 may include a (semi) transparent electrode or a reflective electrode. When the counter electrode 313 includes a (semi) transparent electrode, the counter electrode 313 includes a layer formed of a metal having a low work function and a layer formed of ITO, IZO, ZnO or In 2 O 3 The (semi) transparent conductive layer formed by the metal with low work function such as Li, Ca, lithium fluoride-calcium (LiF / Ca), lithium fluoride-aluminum (LiF / Al), Al, Ag, Mg or their compounds. When the counter electrode 313 includes a reflective electrode, the counter electrode 313 includes a layer formed by at least one of Li, Ca, LiF / Ca, LiF / Al, Al, Ag, Mg and their compounds. However, the embodiment is not limited thereto, and the counter electrode 313 can be variously modified with other structures and materials.

[0069] According to the embodiment, since the display device such as the organic light emitting device 310 includes the counter electrode 313, a preset electrical signal needs to be transmitted to the counter electrode 313 to display an image. Therefore, the electrode power supply line 420 is provided in the peripheral area PA to transmit the preset electrical signal to the counter electrode 313.

[0070] According to an embodiment, when various conductive layers are formed in the display area DA, the electrode power supply line 420 is formed of the same material as that of the conductive layer and is formed simultaneously with the conductive layer. Similar to the source electrode 115a and the drain electrode 115b of the thin film transistor TFT disposed on the interlayer insulating layer 131 in the display area DA, Figure 3 It is shown that in the peripheral area PA, the electrode power supply line 420 is disposed on the interlayer insulating layer 131. In this case, when the source electrode 115a and the drain electrode 115b are formed on the interlayer insulating layer 131 in the display area DA, in the peripheral area PA, the electrode power supply line 420 is formed on the interlayer insulating layer 131 by the same material as the source electrode 115a and the drain electrode 115b and is formed on the interlayer insulating layer 131 at the same time as the source electrode 115a and the drain electrode 115b. Therefore, the electrode power supply line 420 has the same structure as the source electrode 115a and the drain electrode 115b. However, the embodiments of the present disclosure are not limited thereto. Various modifications may be made, such as using the same material as the gate electrode 113 on the gate insulating layer 121 and forming the electrode power supply line 420 at the same time as the gate electrode 113.

[0071] According to the embodiment, Figure 3 , the counter electrode 313 does not directly contact the electrode power supply line 420, but is electrically connected to the electrode power supply line 420 via the protective conductive layer 422. That is, the protective conductive layer 422 is provided on the planarization layer 140 and extends over the electrode power supply line 420 to be connected to the electrode power supply line 420. Therefore, in the peripheral area PA, the counter electrode 313 contacts the protective conductive layer 422, and in the peripheral area PA, the protective conductive layer 422 contacts the electrode power supply line 420.

[0072] like Figure 3 As shown in , according to an embodiment, since the protective conductive layer 422 is disposed on the planarization layer 140, in the display area DA, the protective conductive layer 422 can be formed simultaneously with the components disposed on the planarization layer 140 and formed of the same material as the components disposed on the planarization layer 140. In detail, when the pixel electrode 311 in the display area DA is formed on the planarization layer 140, the protective conductive layer 422 is formed on the planarization layer 140 simultaneously with the pixel electrode 311 in the peripheral area PA. Therefore, the protective conductive layer 422 has the same structure as that of the pixel electrode 311. As shown in FIG. Figure 3As shown in FIG. 1 , the protective conductive layer 422 is not covered by the planarization layer 140, but covers the exposed portion of the electrode power supply line 420. Therefore, as described herein, in the process of forming the first restriction dam 610 or the second restriction dam 620 to be described below, damage to the electrode power supply line 420 can be prevented.

[0073] According to an embodiment, in order to prevent impurities such as oxygen, moisture, etc. from penetrating into the display area DA through the planarization layer 140, as shown in FIG. Figure 3 As shown in FIG. 4 , the planarization layer 140 has an opening 140 b in the peripheral area PA. In addition, when the protective conductive layer 422 is formed, the protective conductive layer 422 fills the opening 140 b. Therefore, when impurities have penetrated into the planarization layer 140 in the peripheral area PA, the impurities can be effectively prevented from penetrating into the planarization layer 140 in the display area DA.

[0074] According to an embodiment, the capping layer 160 is disposed on the counter electrode 313, and the capping layer 160 improves the efficiency of light generated by the organic light-emitting device 310. The capping layer 160 covers the counter electrode 313 and extends outward from the counter electrode 313 to contact the protective conductive layer 422 under the counter electrode 313. Since the counter electrode 313 covers the display area DA and extends toward the edge of the display area DA, the capping layer 160 also covers the display area DA until the boundary of the peripheral area PA outside the display area DA. In order to improve the light efficiency, the capping layer 160 includes one or more organic materials or inorganic materials, such as silicon dioxide (SiO 2 ), Silicon Nitride (SiN x )、ZnO 2 ), titanium dioxide (TiO 2 )、ZrO 2 ), indium tin oxide (ITO), indium zinc oxide (IZO), tri-8-hydroxyquinoline aluminum (Alq 3 ), copper phthalocyanine (CuPc), 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (CBP) or N,N'-di(naphthalene-1-yl)-N,N'-diphenyl-benzidine (a-NPB).

[0075] As described above, according to the embodiment, the capping layer 160 improves the efficiency of light generated from the organic light emitting device 310. For example, the capping layer 160 can improve the light extraction efficiency. The capping layer 160 uniformly improves the efficiency of light in the display area DA. For uniform improvement of the efficiency of light, the capping layer 160 has an upper surface conforming to the shape of the upper surface of the layer below the capping layer 160. That is, as shown in FIG. Figure 3 As shown in , in the region of the cap layer 160 on the counter electrode 313 , the upper surface of the cap layer 160 conforms to the shape of the upper surface of the counter electrode 313 .

[0076] According to an embodiment, the encapsulation layer 500 is disposed above the capping layer 160. The encapsulation layer 500 protects the organic light-emitting device 310 from external moisture or oxygen. To this end, the encapsulation layer 500 extends not only over the display area DA but also over the peripheral area PA outside the display area DA. Figure 3 As shown in FIG. 5 , the encapsulation layer 500 has a multi-layer structure. In detail, the encapsulation layer 500 includes a first inorganic encapsulation layer 510 , an organic encapsulation layer 520 , and a second inorganic encapsulation layer 530 .

[0077] According to an embodiment, the first inorganic encapsulation layer 510 covers the capping layer 160 and includes at least one of silicon oxide, silicon nitride, silicon oxynitride, etc. Since the first inorganic encapsulation layer 510 conforms to the underlying structure, Figure 3 As shown in , the upper surface of the first inorganic encapsulation layer 510 is uneven.

[0078] According to an embodiment, the upper surface of the organic encapsulation layer 520 is relatively flat over the entire display area DA because the organic encapsulation layer 520 covers the first inorganic encapsulation layer 510 and is thicker than the first inorganic encapsulation layer 510. The organic encapsulation layer 520 includes one or more of PET, PEN, PC, PI, polyethylene sulfonate, polyoxymethylene, polyacrylate, and HMDSO.

[0079] According to an embodiment, the second inorganic encapsulating layer 530 covers the organic encapsulating layer 520 and includes at least one of silicon oxide, silicon nitride, silicon oxynitride, etc. The second inorganic encapsulating layer 530 extends outward from the organic encapsulating layer 520 to contact the first inorganic encapsulating layer 510 in the peripheral area PA, thus protecting the organic encapsulating layer 520 from external exposure.

[0080] As such, according to the embodiment, since the encapsulation layer 500 includes the first inorganic encapsulation layer 510, the organic encapsulation layer 520, and the second inorganic encapsulation layer 530, even when cracks occur in the encapsulation layer 500, due to the multi-layer structure of the encapsulation layer 500, the cracks are not connected to each other between the first inorganic encapsulation layer 510 and the organic encapsulation layer 520 or between the organic encapsulation layer 520 and the second inorganic encapsulation layer 530. Therefore, the formation of a path through which external moisture or oxygen penetrates into the display area DA can be prevented or minimized.

[0081] According to an embodiment, when the encapsulation layer 500 is formed, the structure below the encapsulation layer 500 may be damaged. For example, the first inorganic encapsulation layer 510 may be formed by a chemical vapor deposition method. When the first inorganic encapsulation layer 510 is formed by chemical vapor deposition, the layer directly below the first inorganic encapsulation layer 510 may be damaged. Therefore, when the first inorganic encapsulation layer 510 is formed directly on the cap layer 160, if the cap layer 160 is damaged, the light efficiency of the display device 10 may be deteriorated. Therefore, in order to prevent damage to the cap layer 160 when the encapsulation layer 500 is formed, the protective layer 170 is disposed between the cap layer 160 and the encapsulation layer 500. The protective layer 170 includes lithium fluoride (LiF).

[0082] As described above, according to the embodiment, the cover layer 160 extends not only over the display area DA but also into the peripheral area PA outside the display area DA. Therefore, the protective layer 170 extends toward the edge of the cover layer 160 so that the cover layer 160 does not directly contact the encapsulation layer 500. In this case, the protective layer 170 covers the end of the cover layer 160 so that the end of the protective layer 170 is disposed above the planarization layer 140. In detail, as shown in FIG. Figure 3 As shown in FIG. 4 , the end of the protection layer 170 directly contacts the protection conductive layer 422 above the planarization layer 140 .

[0083] According to an embodiment, the bonding strength of the first inorganic encapsulation layer 510, which is the lowest layer in the encapsulation layer 500, and the layer formed of the inorganic material is greater than the bonding strength of the first inorganic encapsulation layer 510 and the layer formed of the organic material. Therefore, when the capping layer 160 includes an organic material and the protective layer 170 is formed of an inorganic material such as LiF, because the bonding strength between the inorganic protective layer 170 and the first inorganic encapsulation layer 510 is greater than the bonding strength between the organic capping layer 160 and the first inorganic encapsulation layer 510, the encapsulation layer 500 is more strongly bonded to the layer below the encapsulation layer 500. Therefore, in the process of manufacturing the display device or using the display device after manufacturing, the delamination of the encapsulation layer 500 and the layer below the encapsulation layer 500 can be effectively prevented or minimized.

[0084] In detail, according to an embodiment, when the encapsulation layer 500 is formed, the material of the organic encapsulation layer 520 needs to be limited to a predetermined area. Figure 3 As shown in FIG. 1 , the first limiting dam 610 is disposed in the peripheral area PA. Figure 3 As shown in FIG. 1 , a buffer layer 110, a gate insulating layer 121, an interlayer insulating layer 131, and a planarization layer 140 are disposed in the peripheral area PA and in the display area DA of the substrate 101. A first confinement dam 610 is disposed separately from the planarization layer 140 in the peripheral area PA.

[0085] According to an embodiment, the first limiting dam 610 has a multi-layer structure. That is, the first limiting dam 610 includes a first layer 611, a second layer 613, and a third layer 615 above the substrate 101. The first layer 611 is formed of the same material as the material of the planarization layer 140 and is formed at the same time as the planarization layer 140. The second layer 613 is formed of the same material as the material of the pixel defining layer 150 and is formed at the same time as the pixel defining layer 150. The third layer 615 is formed of the same material as the material of the pixel defining layer 150.

[0086] like Figure 3 As shown in , according to an embodiment, in addition to the first restriction dam 610, a second restriction dam 620 is formed between the first restriction dam 610 and the planarization layer 140. The second restriction dam 620 is disposed on a portion of the protective conductive layer 422 above the electrode power supply line 420. The second restriction dam 620 is also disposed in the peripheral area PA separately from the planarization layer 140. Similar to the first restriction dam 610, the second restriction dam 620 has a multi-layer structure, and the second restriction dam 620 includes a lower layer 623 formed simultaneously with the second layer 613 of the first restriction dam 610 and an upper layer 625 disposed on the lower layer 623. Therefore, the second restriction dam 620 includes fewer layers than the first restriction dam 610, and the height of the second restriction dam 620 from the substrate 101 is less than the height of the first restriction dam 610 from the substrate 101. Figure 3 It is shown that the lower layer 623 is formed of the same material as the second layer 613 of the first confinement dam 610 and is formed simultaneously with the second layer 613 and the upper layer 625 is formed of the same material as the third layer 615 of the first confinement dam 610 .

[0087] like Figure 3 As shown in , according to an embodiment, when the first inorganic encapsulation layer 510 of the encapsulation layer 500 is formed by chemical vapor deposition, the first inorganic encapsulation layer 510 covers the second confinement dam 620 and the first confinement dam 610, thereby extending to the outer edge of the first confinement dam 610. The material for forming the organic encapsulation layer 520 on the first inorganic encapsulation layer 510 is confined by the second confinement dam 620 to prevent the material from overflowing from the second confinement dam 620 when the organic encapsulation layer 520 is formed. Even when some of the material for forming the organic encapsulation layer 520 overflows from the second confinement dam 620, because the material of the organic encapsulation layer 520 is also confined by the first confinement dam 610, the material for forming the organic encapsulation layer 520 does not flow further toward the edge of the substrate 101.

[0088] like Figure 3 As shown in , according to an embodiment, the crack prevention dam 630 is disposed in the peripheral area PA. The crack prevention dam 630 extends along at least a portion of the edge of the substrate 101. For example, the crack prevention dam 630 surrounds the entire display area DA. In some areas, the crack prevention dam 630 may be disconnected.

[0089] According to embodiments, the crack prevention dam 630 may have various shapes. Figure 3 As shown in , the crack prevention dam 630 is formed of the same material as some components in the display area DA, and may have a multi-layered structure. Figure 3 The crack prevention dam 630 is shown as having a two-layer structure. In detail, Figure 3 It is shown that the crack prevention dam 630 includes a lower layer formed of the same material as that of the gate insulating layer 121 and an upper layer formed of the same material as that of the interlayer insulating layer 131 on the gate insulating layer 121. The crack prevention dam 630 is provided on the buffer layer 110. As needed, the crack prevention dam 630 may be provided on a layer below the buffer layer 110 and include a layer having the same material as that of the buffer layer 110. Alternatively, instead of one crack prevention dam 630, a plurality of crack prevention dams 630 separated from each other may be provided.

[0090] According to an embodiment, the crack prevention dam 630 is formed by removing a portion of the gate insulating layer 121 and a portion of the interlayer insulating layer 131. Figure 3 As shown in FIG, a transmission preventing groove 632 is formed at least on one side of the crack prevention dam 630 by removing a portion of the gate insulating layer 121 and a portion of the interlayer insulating layer 131. Therefore, the crack prevention dam 630 includes a remaining portion of the gate insulating layer 121 and a remaining portion of the interlayer insulating layer 131 adjacent to the transmission preventing groove 632.

[0091] According to an embodiment, the crack prevention dam 630 is covered by a capping layer 650. When the planarization layer 140 is formed in the display area DA, the capping layer 650 is formed of, for example, the same material as that of the planarization layer 140. That is, the capping layer 650 is formed of an organic material covering the crack prevention dam 630 including an inorganic material. The capping layer 650 fills the transmission prevention groove 632 and covers the crack prevention dam 630.

[0092] Figure 4 yes Figure 1 Schematic plan view of portion A of FIG. Figure 5 It is taken along line III-III' Figure 4 1 is a schematic cross-sectional view of an example of a display panel 100 .

[0093] Reference Figure 4 and Figure 5 , according to an embodiment, Figure 1 The input detection unit 200 is directly arranged on Figure 1 On the display panel 100. For example, Figure 1 The input detection unit 200 is directly disposed on the encapsulation layer 500. Therefore, the Figure 1 For example, a thickness of the display device 10 is formed on the substrate. Figure 1 After the input detection unit 200 is formed, the substrate is bonded to the encapsulation layer 500 .

[0094] According to an embodiment, the first detection electrode 210 and the second detection electrode 230 are formed of a transparent conductive layer. The transparent conductive layer includes a transparent conductive oxide such as ITO, IZO, ZnO, or indium tin zinc oxide (ITZO). In addition, the transparent conductive layer includes a conductive polymer such as PEDOT, a metal nanowire, graphene, etc. For example, the first detection electrode 210 and the second detection electrode 230 are formed of a transparent metal layer. In this case, the first detection electrode 210 and the second detection electrode 230 are formed in a mesh form so as to be transparent.

[0095] According to the embodiment, two first detection electrodes 210 adjacent to each other in the first direction D1 are connected to each other via a connector 220. The connector 220 is disposed on the same layer as the first detection electrode 210. The connector 220 is formed integrally with the first detection electrode 210.

[0096] According to an embodiment, two second detection electrodes 230 adjacent to each other in a second direction D2 perpendicular to the first direction D1 are connected to each other via a bridge wire 240. The bridge wire 240 is disposed on a different layer from the first detection electrode 210 and the second detection electrode 230. For example, the bridge wire 240 is disposed on the encapsulation layer 500, the first insulating layer 201 is disposed on the bridge wire 240, and the first detection electrode 210 and the second detection electrode 230 are disposed above the first insulating layer 201. In this case, the bridge wire 240 is electrically connected to the second detection electrode 230 via the first contact hole CNT-I in the first insulating layer 201. In addition, the second insulating layer 202 is disposed above the first detection electrode 210 and the second detection electrode 230.

[0097] According to an embodiment, since the bridge wiring 240 crosses the connector 220, the width of the bridge wiring 240 is minimized when measured in a plane so as to reduce parasitic capacitance between the bridge wiring 240 and the connector 220. In addition, the bridge wiring 240 includes a material having a lower resistance than the second detection electrode 230 so as to improve the sensing sensitivity. For example, the bridge wiring 240 includes one or more of Mo, Ag, Ti, Cu, Al, and alloys thereof.

[0098] According to an embodiment, at least one of the first insulating layer 201 and the second insulating layer 202 includes an inorganic layer, and the inorganic layer is at least one of aluminum oxide, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide.

[0099] According to an embodiment, at least one of the first insulating layer 201 and the second insulating layer 202 includes an organic layer. The organic layer is at least one of an acrylic-based resin, a methacrylic-based resin, polyisoprene, a vinyl resin, an epoxy resin, a urethane-based resin, a cellulose-based resin, a siloxane-based resin, a polyimide-based resin, a polyamide-based resin, and a perylene-based resin.

[0100] According to the embodiment, the first insulating layer 201 and the second insulating layer 202 are disposed over the entire display area DA of the display panel 100, and the input detection unit 200 is disposed on the display panel 100. Therefore, the refractive index of the first insulating layer 201 is smaller than the refractive index of the second insulating layer 202, thereby improving Figure 2 The light extraction efficiency of the display panel 100 is improved.

[0101] Figure 4 and Figure 5 An embodiment is shown in which the bridge wire 240 is disposed on a layer below the layer of the connector 220. However, the embodiments of the present disclosure are not limited thereto, and the bridge wire 240 may be disposed on a layer above the layer of the connector 220. In addition, two or more bridge wires 240 may be used.

[0102] In addition, according to the embodiment, a floating dummy pattern that is not connected to the first detection electrode 210 or the second detection electrode 230 is further provided between the first detection electrode 210 and the second detection electrode 230. Since the dummy pattern is provided in the same layer as the first detection electrode 210 and the second detection electrode 230, the visibility of the boundary between the first detection electrode 210 and the second detection electrode 230 is reduced.

[0103] Figure 6 yes Figure 1 Schematic plan view of portion B of FIG. Figure 7 yes Figure 6 Schematic plan view of portion C of FIG. Figure 8 It is taken along line IV-IV' Figure 7 1 is a schematic cross-sectional view of an example of a display panel 100. Figure 1 and Figures 6 to 8 Description is provided. In addition, for convenience of description, a region in which the first detection electrode 210 and the second detection electrode 230 are disposed is referred to as a touch region TA.

[0104] Reference Figure 1 and Figures 6 to 8According to the embodiment, the first sensing electrode array 210-1 has a cross section cut by the recess T. Therefore, the first sensing electrodes 210 of the first sensing electrode array 210-1 on both sides of the recess T are electrically connected to each other through the connection wiring 250. The connection wiring 250 is disposed above the encapsulation layer 500 outside the touch area TA.

[0105] According to an embodiment, the connection wiring 250 includes a plurality of segments 251 separated from each other and a junction portion 260 electrically connecting two adjacent segments 251 .

[0106] According to an embodiment, the plurality of segments 251 and Figure 4 and Figure 5 As shown in and referenced Figure 4 and Figure 5 The bridge wiring 240 is provided on the same layer as described above and includes Figure 4 The material of the bridge wiring 240 is the same as that of the bridge wiring 240 . In addition, the bonding portion 260 is provided on the same layer as the first detection electrode 210 and the second detection electrode 230 , and includes the same material as that of the first detection electrode 210 and the second detection electrode 230 .

[0107] Therefore, in an embodiment, a plurality of segments 251 are disposed on the encapsulation layer 500, a first insulating layer 201 is disposed on the plurality of segments 251, and a bonding portion 260 is disposed on the first insulating layer 201. In this case, the bonding portion 260 is electrically connected to the plurality of segments 251 via the second contact hole CNT-II in the first insulating layer 201. In addition, the second insulating layer 202 is disposed on the bonding portion 260.

[0108] As such, according to the embodiment, when the connection wiring 250 includes a plurality of sections 251, the amount of charge accumulated in the connection wiring 250 is reduced compared to when the connection wiring 250 is formed as one body. Therefore, a phenomenon in which the first insulating layer 201 or the second insulating layer 202 is destroyed when the accumulated charge is discharged can be prevented, and damage to the input detection unit 200 can be prevented or reduced.

[0109] According to an embodiment, the input detection unit 200 includes a connection line CL connecting the first detection electrode 210 or the second detection electrode 230 to the pad, and a dummy line DL in a floating state is disposed at the periphery of the touch area TA. That is, by placing the dummy line DL in an empty space at the periphery of the touch area TA, the visibility of the connection line CL can be reduced. In addition, since the connection line CL, the dummy line DL, and the plurality of segments 251 are disposed on the same layer, the dummy line DL is disposed between the connection line CL and the plurality of segments 251 to prevent a short circuit between the connection line CL and the plurality of segments 251.

[0110] Fig. 9 and Fig.10 yes Figure 6 Schematic plan views of other examples of portion C.

[0111] Reference Fig. 9 and Fig.10 According to an embodiment, the connection line CL, the dummy line DL, and the segment 251 are disposed outside the touch area TA. The dummy line DL disposed between the connection line CL and the segment 251 includes a cutout portion CP of which a portion is removed. The segment 251 includes an extension portion 252 extending from an end of the segment 251 into the cutout portion CP. The extension portion 252 may be wider than the width of the segment 251. In addition, the connector 262 connecting the segments 251 to each other is disposed to overlap the extension portion 252. The contact hole connecting the connector 262 to the extension portion 252 is larger than Figure 8 Alternatively, the connector 262 is connected to the extension 252 via a plurality of contact holes.

[0112] As described above, according to the embodiment, it is necessary to adjust the width of the connection wiring 250 so that the resistance value of the first detection electrode array 210-1 including the pairs of first detection electrodes 210 electrically connected to each other via the connection wiring 250 is equal to the resistance value of the other first detection electrode arrays 210-2 in which the first detection electrodes 210 are continuously provided. Therefore, the section 251 includes the expansion portion 252 so that the first detection electrode array 210-1 has the same resistance as the resistance of the other first detection electrode arrays 210-2 even when the width of the connection wiring 250 is small.

[0113] According to the embodiment, since the connection wiring connecting the first detection electrodes on both sides of the concave portion of the display device includes a plurality of sections, the amount of charge accumulated in the connection wiring is reduced, thereby preventing the input detection unit from being damaged by electrostatic discharge. However, the embodiments of the present disclosure are not limited thereto.
