[0052] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0053] When a phrase such as "one of" is placed after a list of elements, it modifies the entire list of elements rather than the individual elements in the list.

[0054] It will be understood that although the terms "first", "second", etc. may be used herein to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from another component.

[0055] As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0056] It will also be understood that the terms “comprises / includes” used herein specify the presence of stated features or components, but do not preclude the presence or addition of one or more other features or components.

[0057] It will be understood that when a layer, region or 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. That is, for example, one or more intermediate layers, regions or components may be present.

[0058] For the convenience of explanation, the size of the elements in the drawings may be exaggerated. In other words, since the size and thickness of the components in the drawings are arbitrarily shown for the convenience of explanation, the following embodiments are not limited thereto.

[0059] When a certain embodiment can be implemented differently, a specific process order can be performed in a different order than described. For example, two consecutively described processes can be performed substantially simultaneously or in a reverse order to the described order.

[0060] It will be understood that when a layer, region, or component is referred to as being "connected" to another layer, region, or component, the layer, region, or component may be directly connected to the other layer, region, or component, or may be indirectly connected to the other layer, region, or component with one or more other layers, regions, or components interposed therebetween.

[0062] Figure 1 is a perspective view of a display device 1 according to the embodiment.

[0063] Reference Figure 1 The display device 1 includes a display area DA and a non-display area NDA that does not emit light. The non-display area NDA is adjacent to the display area DA. The display device 1 can generate an image (eg, a predetermined image) by using light emitted from a plurality of pixels arranged in the display area DA.

[0064] The display device 1 includes an opening area OA at least partially surrounded by a display area DA. Figure 1As shown in , the opening area OA is completely surrounded by the display area DA. In an embodiment, the non-display area NDA includes a first non-display area NDA1 surrounding the opening area OA and a second non-display area NDA2 surrounding the display area DA. In an embodiment, the first non-display area NDA1 may completely surround the opening area OA, the display area DA may completely surround the first non-display area NDA1, and the second non-display area NDA2 may completely surround the display area DA.

[0065] Although an organic light emitting display device is exemplarily described below as the display device 1 according to the embodiment, the display device 1 is not limited thereto. In another embodiment, any of various types of display devices such as an inorganic light emitting display device and a quantum dot light emitting display device may be used.

[0066] Figure 2 is a cross-sectional view of a display device 1 according to an embodiment, and may correspond to a cross-sectional view along Figure 1 A cross section taken along line II'.

[0067] Reference Figure 2 , the display device 1 may include a display panel 10, and an input sensing layer 40 and an optical functional layer 50 arranged on the display panel 10. These layers may be covered by a window 60. The display device 1 may include any of various electronic devices, such as a mobile phone, a notebook computer, and a smart watch.

[0068] The display panel 10 may display an image. The display panel 10 includes pixels arranged in a display area DA. Each of the pixels may include a display element and a pixel circuit connected to the display element. The display element may include an organic light emitting diode, an inorganic light emitting diode, or a quantum dot light emitting diode.

[0069] The input sensing layer 40 obtains coordinate information corresponding to an external input (eg, a touch event). The input sensing layer 40 may include sensing electrodes (or touch electrodes) and traces connected to the sensing electrodes. The input sensing layer 40 may be arranged on the display panel 10.

[0070] The input sensing layer 40 may be directly formed on the display panel 10, or may be separately formed and then bonded to the display panel 10 by using an adhesive layer such as an optically clear adhesive (OCA). For example, the input sensing layer 40 may be formed sequentially after a process of forming the display panel 10. In this case, the adhesive layer may not be disposed between the input sensing layer 40 and the display panel 10. Although Figure 2 It is shown that the input sensing layer 40 is disposed between the display panel 10 and the optical functional layer 50 , but in another embodiment, the input sensing layer 40 may be disposed on the optical functional layer 50 .

[0071] The optical functional layer 50 may include an anti-reflection layer. The anti-reflection layer may reduce the reflectivity of light (external light) incident from the outside through the window 60 toward the display panel 10. In an embodiment, the anti-reflection layer may include a retarder and a polarizer. The retarder may include a film-type retarder or a liquid crystal retarder. The retarder may include a λ / 2 retarder and / or a λ / 4 retarder. The polarizer may include a film-type polarizer or a liquid crystal polarizer. The film-type polarizer may include a stretchable synthetic resin film, and the liquid crystal polarizer may include liquid crystals arranged in a predetermined arrangement. Each of the retarder and the polarizer may also include a protective film. The retarder and the polarizer themselves or their protective films may be defined as a substrate layer of the anti-reflection layer.

[0072] In another embodiment, the anti-reflection layer may include a black matrix and a color filter. The color filter may be arranged in consideration of the color of the light emitted from the pixels of the display panel 10, respectively. In another embodiment, the anti-reflection layer may include a destructive interference structure. The destructive interference structure may include a first reflective layer and a second reflective layer respectively arranged in different layers. The first reflected light and the second reflected light respectively reflected by the first reflective layer and the second reflective layer may generate destructive interference, and thus the reflectivity of the external light may be reduced.

[0073] The optical function layer 50 may include a lens layer. The lens layer may improve the emission efficiency of light emitted from the display panel 10 or reduce the color deviation of the light. The lens layer may include a layer having a concave lens shape or a convex lens shape and / or include a plurality of layers having different refractive indices, respectively. The optical function layer 50 may include both an anti-reflection layer and a lens layer, or may include one of the anti-reflection layer and the lens layer.

[0074] The display panel 10, the input sensing layer 40 and / or the optical function layer 50 may include an opening. In this regard, Figure 2 It is shown that the display panel 10, the input sensing layer 40 and the optical function layer 50 include a first opening 10H, a second opening 40H and a third opening 50H, respectively, and the first opening 10H, the second opening 40H and the third opening 50H thereof overlap each other. The first opening 10H, the second opening 40H and the third opening 50H are positioned to correspond to the opening area OA. In another embodiment, at least one of the display panel 10, the input sensing layer 40 and the optical function layer 50 may not include an opening. For example, one or two of the display panel 10, the input sensing layer 40 and the optical function layer 50 may not include an opening. Here, the opening area OA may represent at least one of the first opening 10H of the display panel 10, the second opening 40H of the input sensing layer 40 and the third opening 50H of the optical function layer 50. For example, in the present specification, the opening area OA may represent the first opening 10H of the display panel 10.

[0075] The component 20 may correspond to the opening area OA. Figure 2 The component 20 may be located in the first opening 10H, the second opening 40H, and the third opening 50H as shown by the solid lines in FIG. 1 , or the component 20 may be located below the display panel 10 as shown by the dotted lines.

[0076] Component 20 may include electronic components. For example, component 20 may include electronic components that use light or sound, etc. For example, the electronic component may be a sensor that emits and / or receives light (such as an infrared sensor), a camera that receives light and captures an image, a sensor that outputs and senses light or sound to measure distance or recognize fingerprints, a small lamp that outputs light, and / or a speaker that outputs sound. Electronic components that use light can use light in various bands, such as visible light, infrared light, and ultraviolet light. In an embodiment, the opening area OA may be understood as a transmission area, and light and / or sound output from component 20 to the outside or light and / or sound propagating from the outside toward the electronic component may pass through the transmission area.

[0077] In another embodiment, in the case where the display device 1 is used as a smart watch or a dashboard for a car, for example, the component 20 may be a member including a clock hand or a pointer indicating predetermined information (e.g., the speed of the vehicle, etc.). In the case where the display device 1 includes the component 20 (such as a clock hand or a dashboard for a car), the component 20 may be exposed to the outside through the window 60, and the window 60 may include an opening corresponding to the opening area OA.

[0078] As described above, the assembly 20 may include one or more elements related to the function of the display panel 10 or elements such as accessories that enhance the aesthetics of the display panel 10 .

[0079] Despite Figure 2 , the window 60 is shown to be spaced apart from the optical function layer 50 by a spacing (eg, a predetermined spacing), but a layer including the OCA may be located between the window 60 and the optical function layer 50 .

[0080] Figure 3 is a plan view of a display panel 10 according to an embodiment; Figure 4 is an equivalent circuit diagram of one of the pixels P of the display panel 10 .

[0081] Reference Figure 3 , the display panel 10 includes a display area DA, a first non-display area NDA1 and a second non-display area NDA2. Figure 3It can be understood as a diagram of the substrate 100. For example, it can be understood that the substrate 100 includes an opening area OA, a display area DA, a first non-display area NDA1, and a second non-display area NDA2. Although not shown, the substrate 100 may include an opening corresponding to the opening area OA, for example, an opening passing through the top and bottom surfaces of the substrate 100.

[0082] The display panel 10 includes a plurality of pixels P arranged in a display area DA. Figure 4 As shown in , each pixel P includes a pixel circuit PC and an organic light emitting diode OLED connected to the pixel circuit PC as a display element. The pixel circuit PC may include a first transistor T1, a second transistor T2 and a capacitor Cst. Each pixel P may emit, for example, red light, green light, blue light or white light through the organic light emitting diode OLED. The first transistor T1 and the second transistor T2 may be implemented as thin film transistors.

[0083] The second transistor T2 is a switching thin film transistor connected to the scan line SL and the data line DL, and can transmit the data voltage input from the data line DL to the first transistor T1 in response to the switching voltage input from the scan line SL. The capacitor Cst can be connected to the second transistor T2 and the driving voltage line PL, and can store a voltage corresponding to the difference between the voltage transmitted from the second transistor T2 and the first power supply voltage ELVDD supplied from the driving voltage line PL.

[0084] The first transistor T1 is a driving thin film transistor, which can be connected to the driving voltage line PL and the capacitor Cst, and can control the driving current flowing from the driving voltage line PL through the organic light emitting diode OLED in response to the voltage stored in the capacitor Cst. The organic light emitting diode OLED can emit light with brightness (e.g., predetermined brightness) by using the driving current. The counter electrode (e.g., cathode) of the organic light emitting diode OLED can receive the second power supply voltage ELVSS.

[0085] although Figure 4 2 shows that the pixel circuit PC includes two transistors and one capacitor, but the present disclosure is not limited thereto. The number of transistors and the number of capacitors may be variously changed according to the design of the pixel circuit PC.

[0086] Refer again Figure 3, the first non-display area NDA1 may surround the opening area OA. The first non-display area NDA1 is an area in which a display element such as an organic light emitting diode OLED is not arranged. A signal line configured to provide a signal to the pixels P arranged around the opening area OA may cross the first non-display area NDA1, or a groove to be described below may be arranged in the first non-display area NDA1. A scan driver 1100 configured to provide a scan signal to each pixel P, a data driver 1200 configured to provide a data signal to each pixel P, a main power wiring (not shown) configured to provide a first power voltage ELVDD and a second power voltage ELVSS, etc. may be arranged in the second non-display area NDA2. Although in Figure 3 The data driver 1200 is shown to be adjacent to one side of the substrate 100, but according to another embodiment, the data driver 1200 can be arranged on a flexible printed circuit board (FPCB), and the flexible printed circuit board (FPCB) is electrically connected to a pad (also referred to as a "pad") arranged on one side of the display panel 10.

[0087] Figure 5 is a plan view of a portion of the display panel 10 according to the embodiment, and illustrates wirings (eg, signal lines) located in the first non-display area NDA1.

[0088] Reference Figure 5 , the pixels P may be arranged around the opening area OA in the display area DA, and the first non-display area NDA1 may be arranged between the opening area OA and the display area DA.

[0089] The pixels P may be spaced apart from each other around the opening area OA. The pixels P may be spaced apart up and down around the opening area OA, or may be spaced apart left and right around the opening area OA.

[0090] Signal lines adjacent to the opening area OA among signal lines configured to supply signals to the pixels P may be routed (or bypassed) around the opening area OA. Some of the data lines DL crossing the display area DA may extend in the y direction to supply data signals to pixels P arranged up and down with the opening area OA interposed therebetween, and bypass along the edge of the opening area OA in the first non-display area NDA1. Some of the scan lines SL crossing the display area DA may extend in the x direction to supply scan signals to pixels P arranged left and right with the opening area OA interposed therebetween, and bypass along the edge of the opening area OA in the first non-display area NDA1.

[0091] Figure 6is a plan view of a portion of the display panel 10 according to an embodiment, and illustrates the metal layer 30 and the signal line located in the first non-display area NDA1.

[0092] Reference Figure 6 , the metal layer 30 is arranged in the first non-display area NDA1 surrounding the opening area OA. The width W1 of the metal layer 30 may be smaller than the width W0 of the first non-display area NDA1. Alternatively, the width W1 of the metal layer 30 may be the same as the width W0 of the first non-display area NDA1. Here, the width W1 of the metal layer 30 and the width W0 of the first non-display area NDA1 may respectively refer to the distance in the radial direction from the center CO of the opening area OA.

[0093] The metal layer 30 may include a metal that does not transmit light (i.e., has a light blocking property). For example, the metal layer 30 may include any one of Mo, Al, Cu, and Ti, and may include a single layer or multiple layers including any one of the above materials. In an embodiment, the metal layer 30 may include a multiple layer including Ti / Al / Ti.

[0094] The metal layer 30 may cover the signal lines arranged thereunder, for example, Figure 5 The metal layer 30 may prevent or substantially prevent the light reflected by the data line DL and / or the scan line SL from being provided to the user by blocking the light traveling from the outside to the data line DL and / or the scan line SL.

[0095] The metal layer 30 may include a plurality of regions. The plurality of regions may be spaced apart from each other. Figure 6 3 shows that the metal layer 30 includes a first region 310, a second region 320, a third region 330, a fourth region 340, and a fifth region 350, but the present disclosure is not limited thereto. The metal layer 30 may include two or more regions, and the number of regions may be variously changed.

[0096] In an embodiment, the first region 310, the second region 320, the third region 330, the fourth region 340 and the fifth region 350 may be arranged in a peripheral direction around the edge of the opening area OA. The first region 310, the second region 320, the third region 330, the fourth region 340 and the fifth region 350 may be spaced apart from each other.

[0097] In an embodiment, a reference may be formed Figure 2The metal layer 30 is formed simultaneously (eg, synchronously) during the process of the described input sensing layer 40. With regard to the structure of the metal layer 30, the input sensing layer 40 is first described below, and then the structure of the metal layer 30 is described.

[0098] Figure 7 is a plan view of an input sensing layer 40 of a display panel 10 according to an embodiment; Figure 8 is along Figure 7 A cross-sectional view of the input sensing layer 40 taken along line II-II'; Fig.9A yes Figure 8 A plan view of a first conductive layer CML1; FIG. 9B to FIG. 9D yes Figure 8 FIG. 5 is a plan view of an embodiment of a second conductive layer CML2 .

[0099] Reference Figure 7 , the input sensing layer 40 may include a first sensing electrode 410, first traces 415-1, 415-2, 415-3, and 415-4 connected to the first sensing electrode 410, a second sensing electrode 420, and second traces 425-1, 425-2, 425-3, 425-4, and 425-5 connected to the second sensing electrode 420. The input sensing layer 40 may sense the external input using a mutual capacitance method and / or a self capacitance method.

[0100] The first sensing electrodes 410 may be arranged in the y direction, and the second sensing electrodes 420 may be arranged in the x direction intersecting or crossing the y direction.

Fig.13 As shown in FIG. 1 , a portion of the first sensing electrode 410 and the second sensing electrode 420 may be located in the first non-display area NDA1. The region electrically connected to the second sensing electrode 420 (e.g., the second region 320, the third region 330, and the fifth region 350) does not overlap the first electrode 411A of the first sub-connection electrode 411S.

[0128] Despite Fig.10, the areas of the two first sensing electrodes 410 and the four second sensing electrodes 420 are shown to be different from the areas of the other sensing electrodes due to the opening area OA, but the present disclosure is not limited thereto. The arrangement of the first sensing electrodes 410 and the second sensing electrodes 420 around the opening area OA may vary, and the areas of the first sensing electrodes 410 and the second sensing electrodes 420 may vary according to the position and / or size of the opening area OA. Depending on the position and / or size of the opening area OA, the touch sensitivity or sensing sensitivity around the opening area OA may be significantly reduced. As described above, in the case where at least a portion of the first area 310, the second area 320, the third area 330, the fourth area 340, and the fifth area 350 of the metal layer 30 are connected to the first sensing electrode 410 or the second sensing electrode 420, one or more areas may perform the function of the sensing electrode and may improve the touch sensitivity around the opening area OA.

In another embodiment, the areas (or sizes) of the first region 310, the second region 320, the third region 330, the fourth region 340, and the fifth region 350 may be the same. The areas or sizes of the first region 310, the second region 320, the third region 330, the fourth region 340, and the fifth region 350 may be determined according to the position and / or size of the opening area OA. Depending on the position and / or size of the opening area OA, the number of regions of the metal layer 30 may vary. Although in Fig.10 4 shows that the first region 310 and the fourth region 340 connected to the first sensing electrode 410 are respectively adjacent to the second sensing electrode 420, and the second region 320, the third region 330 and the fifth region 350 connected to the second sensing electrode 420 are respectively adjacent to the first sensing electrode 410, but the present disclosure is not limited thereto. In another embodiment, the electrical connection and arrangement of these regions may be as follows: Fig.14 Varies as described.

[0130] Fig.14 FIG. 1 is a conceptual diagram of a metal layer 30 and a sensing electrode of a display device 1 according to another embodiment. Fig.14 It is shown in FIG. 4 that the metal layer 30 includes six regions.

For example, each of the first region 310' and the fourth region 340' may be electrically connected to the second sensing electrode 420. The second region 320', the third region 330', the fifth region 350', and the sixth region 360' may be electrically connected to the first sensing electrode 410. That is, the region arranged between the opening region OA and one of the sensing electrodes may receive a voltage different from the voltage of the one of the sensing electrodes.

[0132] like Fig.10 and Fig.14 As shown in , the areas or sizes of the sensing electrodes adjacent to the opening area OA may be different from each other. For example, the area or size of the second sensing electrode 420 may be larger than the area or size of the first sensing electrode 410. Fig.14 , it is shown that the area or size of the region adjacent to the sensing electrode having a relatively small area among the electrodes around the opening area OA is larger than the area or size of the region adjacent to the sensing electrode having a relatively large area among the electrodes around the opening area OA. Fig.10 , the area or size of the first region 310 and the fourth region 340 adjacent to the second sensing electrode 420 having a relatively small area or size may be larger than the area or size of the second region 320, the third region 330, and the fifth region 350 adjacent to the first sensing electrode 410 having a relatively large area or size. Fig.14 , the area or size of the second region 320' adjacent to the second sensing electrode 420 having a relatively small area or size may be larger than the area or size of the first region 310' adjacent to the first sensing electrode 410 having a relatively large area or size. However, the present disclosure is not limited thereto. In another embodiment, the area or size of the second region 320' adjacent to the second sensing electrode 420 having a relatively small area or size may be smaller than the area or size of the first region 310' adjacent to the first sensing electrode 410 having a relatively large area or size. Although Fig.14 Although not shown separately, the sensing electrodes spaced apart from each other around the opening area OA may be connected to each other to form rows or columns. For example, the first sensing electrodes 410 above and below the opening area OA may be connected to each other by referring to the above. Fig.10 The first sub-connection electrodes 411S described above are connected to each other. Similarly, the second sensing electrodes 420 on the lower right and lower left sides of the opening area OA can be connected by referring to Fig.10The second sub connection electrodes 421S described as being connected to each other, the second sensing electrodes 420 on the upper right and left sides of the opening area OA may be connected to each other through electrodes (not shown) similar to the second sub connection electrodes 421S.

Metal layer 30 may include regions 310, 320, 330, 340, and 350 having an area or size corresponding to an electrode area removed from first sensing electrode 410 or second sensing electrode 420. For example, when the electrode area removed from first sensing electrode 410 or second sensing electrode 420 is large, the area or size of a region of metal layer 30 adjacent to first sensing electrode 410 or second sensing electrode 420 may be large.

[0136] Although not shown, the second region 320, the third region 330, and the fifth region 350 adjacent to the first sensing electrode 410 that has been partially removed may be electrically connected to the second sensing electrode 420 around the opening area OA.

The virtual boundary line BL (referred to herein as the boundary line BL) is defined as the center line of the separation space between the facing edges of a pair of mutually adjacent regions of the metal layer 30 passing through and making the facing edges continuously parallel in a straight line. That is, the distance between the facing edges and the center line is the same. Here, the distance between the facing edges and the center line is omitted.

[0169] Figure 23 to Figure 27 is an enlarged plan view of the metal layer 30 according to an embodiment.

[0170] Here, for convenience of description, the first and second regions adjacent to each other of the metal layer 30 are described as an example. One of the first and second regions may be electrically connected to the first sensing electrode 410 , and the other of the first and second regions may be electrically connected to the second sensing electrode 420 .

[0171] Reference Fig.23 , the second region 30E21 may include a protrusion 30EP1 extending beyond the boundary line BL toward the first region 30E11, and the first region 30E11 may have a shape that accommodates the protrusion 30EP1 of the second region 30E21. The protrusion 30EP1 of the second region 30E21 has a width W that decreases away from the boundary line BL, and has an oblique line-shaped side. The side of the first region 30E11 facing the second region 30E21 may have an oblique line shape corresponding to the protrusion 30EP1 of the second region 30E21. Therefore, the first region 30E11 and the second region 30E21 are arranged alternately in an oblique line, and the length of the sides facing each other can be increased compared to the case where the sides parallel to the boundary line BL are set.

[0172] Reference Fig.24 , the second region 30E22 may include a protrusion 30EP2 extending beyond the boundary line BL toward the first region 30E12, and the first region 30E12 may have a shape to accommodate the protrusion 30EP2 of the second region 30E22. The protrusion 30EP2 of the second region 30E22 has a rectangular line shape and can be accommodated in a space formed in one side of the first region 30E12. Therefore, the first region 30E12 and the second region 30E22 are alternately arranged, and the length of the sides facing each other can be increased compared to the case where the sides parallel to the boundary line BL are set. In an embodiment, the width W2 of the protrusion 30EP2 of the second region 30E22 may be constant. The width W2 of the protrusion 30EP2 of the second region 30E22 may be equal to, greater than, or less than the width W1 of the corresponding portion of the first region 30E12. Fig.24 An example is shown in which the width W2 of the protrusion 30EP2 of the second region 30E22 is larger than the width W1 of the portion of the first region 30E12 corresponding to the protrusion 30EP2 of the second region 30E22.

[0173] Reference Fig.25 , the second region 30E23 may include a protrusion 30EP3 extending beyond the boundary line BL toward the first region 30E13, and the first region 30E13 may have a shape to accommodate the protrusion 30EP3 of the second region 30E23. In an embodiment, the protrusion 30EP3 of the second region 30E23 may include a first portion 30EP31 having a rectangular line shape and a second portion 30EP32 having a square shape. The width W1 of the first portion 30EP31 may be smaller than the width W2 of the second portion 30EP32. The protrusion 30EP3 of the second region 30E23 may be accommodated in a space formed in the first region 30E13. Therefore, compared with a case where an edge parallel to the boundary line BL is set to the first region 30E13 and the second region 30E23, the length of the facing edges of the first region 30E13 and the second region 30E23 may be increased.

The protrusion 30EP4 of the second region 30E24 may have a sawtooth shape and may be accommodated in a corresponding space of the first region 30E14. Therefore, compared with a case where an edge parallel to the boundary line BL is provided to the first region 30E14 and the second region 30E24, the length of the facing edge of the first region 30E14 and the second region 30E24 may be increased.

[0175] Reference Fig. 27 , the second region 30E25 may include a protrusion 30EP5 extending beyond the boundary line BL toward the first region 30E15, and the first region 30E15 may have a shape to accommodate the protrusion 30EP5 of the second region 30E25. The protrusion 30EP5 of the second region 30E25 may have a rounded edge shape and may be accommodated in a corresponding space of the first region 30E15. Therefore, compared with the case where the edge parallel to the boundary line BL is set to the first region 30E15 and the second region 30E25, the length of the facing edge of the first region 30E15 and the second region 30E25 may be increased.

In another embodiment, the first region having a relatively large area may include a protrusion protruding toward the second region having a small area.

Fig.28 The first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5 arranged in the second sub non-display area SNDA2 are shown. In an embodiment, each of the first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5 may have an undercut structure. The first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5 may be formed in a multilayer including an inorganic layer and an organic layer. For example, the first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5 may be formed by removing a portion of the substrate 100 including a plurality of layers.

[0204] In an embodiment, each of the first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5 may be formed by etching the second base layer 103 of the substrate 100 and the second inorganic layer 104 thereon.

Fig.28 FIG. 2 shows that the buffer layer 201 on the second inorganic layer 104 is removed simultaneously (eg, synchronously) with the second inorganic layer 104. Fig.28 The buffer layer 201 and the second inorganic layer 104 are represented by different figure marks respectively, but the buffer layer 201 can be understood as one layer of the layers of the multi-layer second inorganic layer 104, or the second inorganic layer 104 can be understood as one layer of the layers of the multi-layer buffer layer 201.

[0205] In an embodiment, each of the first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5 may have an undercut structure in which the width through the second base layer 103 is greater than the width through (one or more) inorganic insulating layers (e.g., the second inorganic layer 104 and / or the buffer layer 201). Through the undercut structure of the first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5, a portion 222' of the intermediate layer 222 (e.g., the first functional layer and the second functional layer) and the counter electrode 223 may be disconnected. Fig.28 It is shown in FIG. 2 that a portion 222 ′ of the intermediate layer 222 and the counter electrode 223 are disconnected around the first groove G1 , the second groove G2 , the third groove G3 , the fourth groove G4 , and the fifth groove G5 .

[0206] In an embodiment, the first inorganic encapsulation layer 231 of the thin film encapsulation layer 230 may cover the inner surfaces of the first groove G1, the second groove G2, the third groove G3, the fourth groove G4, and the fifth groove G5.

In an embodiment, the organic encapsulation layer 232 may be formed by coating a monomer over the substrate 100 and hardening the monomer. In an embodiment, a partition wall 510 may be provided between the first groove G1 and the second groove G2 so as to control the flow of the monomer and ensure the thickness of the monomer (or the organic encapsulation layer 232). The partition wall 510 may include an organic insulating material.

[0207] In an embodiment, during the process of forming the organic encapsulation layer 232, the material of the organic encapsulation layer 232 may exist in some grooves. Fig.28 FIG. 4 shows that the organic material 232A exists in the second groove G2 and the fourth groove G4 .

[0208] The second inorganic encapsulating layer 233 is disposed on the organic encapsulating layer 232 , and may directly contact the first inorganic encapsulating layer 231 on the second groove G2 , the third groove G3 , the fourth groove G4 , and the fifth groove G5 .

[0211] The planarization layer 600 may extend on the thin film encapsulation layer 230 and may be spatially separated from the organic encapsulation layer 232 by the second inorganic encapsulation layer 233. For example, since the planarization layer 600 is arranged on the second inorganic encapsulation layer 233 and the organic encapsulation layer 232 is arranged under the second inorganic encapsulation layer 233, the organic encapsulation layer 232 and the planarization layer 600 may be spatially separated from each other. The organic encapsulation layer 232 and the planarization layer 600 may not be in direct contact with each other. In an embodiment, the planarization layer 600 may have a thickness of 5 μm or more.

Figure 8 As shown in FIG. 4 , at least one insulating layer (eg, a first insulating layer 41 and a second insulating layer 43 ) may be further disposed between the planarization layer 600 and the metal layer 30 and between the planarization layer 600 and the input sensing layer 40 .
