Description

Technical Field

[0001] This disclosure relates to a display device, and more specifically, for example, but not limited to, a display device for preventing organic insulating materials from acting as a path for moisture flow. Background Technology

[0002] The content described in this section is provided only as background information about this disclosure and does not constitute prior art.

[0003] Display devices are used in electronic devices across various fields. For example, display devices can be used to display information inside a vehicle. Display devices installed inside a vehicle can provide information displays or warning displays for the driver. Furthermore, display devices can provide images for passengers. Additionally, display devices may include functions that provide information to users and allow users to input information via touch functionality.

[0004] As the proportion of electronic devices in vehicles increases, so too does the number and types of display devices installed inside vehicles, and the area occupied by these displays. However, the information, images, or videos displayed on these screens can be of a type unrelated to the driver's driving, and therefore may interfere with the driver's work. Consequently, research into vehicle display devices that do not interfere with driver operation is increasing.

[0005] The descriptions provided in the discussion section of the Related Art section should not be construed as prior art simply because they are mentioned in or associated with that section. The discussion in the Related Art section may include information describing one or more aspects of the subject art, and the descriptions in that section do not limit this application. Summary of the Invention

[0006] Driving may be obstructed when unwanted images or information from a display device located inside the vehicle are displayed on the window in the fore-and-aft direction of the driver's seat. Therefore, components for adjusting the viewing angle can be included in the display device to avoid disturbing the driver while driving.

[0007] Components used for viewing angle adjustment may be susceptible to moisture penetration. For example, moisture can penetrate into the display area through organic insulating materials. When moisture penetrates the display area, it can cause corrosion of the metal wires.

[0008] In particular, when a metal wire, such as a touch line, is damaged in a display device that is capable of sensing the user's touch input, a defect may occur during touch operation, which could lead to a product defect.

[0009] Therefore, the inventors of this disclosure have invented a display device for preventing organic insulating materials from acting as moisture flow paths through various experiments.

[0010] The technical objective of the exemplary embodiments of this disclosure is to provide a display device that can improve product reliability by preventing touch lines from being damaged by moisture penetration.

[0011] Furthermore, the technical objective of the exemplary embodiments of this disclosure is to provide a display device capable of maintaining the uniformity of thickness of a protective member that protects components used for adjusting viewing angles.

[0012] Furthermore, the technical objective of the exemplary embodiments of this disclosure is to provide a display device that can reduce greenhouse gas emissions by reducing the production energy required to manufacture the display device.

[0013] The purposes of this disclosure are not limited to those described above. Other purposes and advantages not mentioned in this disclosure may be understood based on the following description and may be more clearly understood based on embodiments according to this disclosure. Furthermore, it will be readily understood that the purposes and advantages of this disclosure can be achieved using the apparatus or combinations thereof shown in the claims.

[0014] A display device according to an exemplary embodiment of the present disclosure includes: a substrate, the substrate including a display area and a non-display area disposed outside the display area; a frame area located in the non-display area and including a first area having a plurality of first structures; an encapsulation portion disposed on the plurality of first structures; a touch sensing unit disposed on the encapsulation portion and including a touch sensor and a touch insulating layer; and a first trench penetrating the touch insulating layer in the first area.

[0015] A display device according to another exemplary embodiment of the present disclosure includes: a substrate including a display area and a non-display area disposed outside the display area; a frame area located in the non-display area and including a first area having a plurality of encapsulation dams; an organic insulating layer disposed above the plurality of encapsulation dams; a lens disposed on the organic insulating layer; one or more trenches penetrating the organic insulating layer in the first area; and a lens dam filling the one or more trenches.

[0016] A display device according to an exemplary embodiment of this disclosure may include an assembly for dividing a touch insulating layer made of an organic insulating material into two isolated portions in a bezel region. Therefore, this assembly can prevent moisture from penetrating through the touch insulating layer into the display area, thereby improving product reliability.

[0017] Furthermore, in the display device according to the exemplary embodiments of the present disclosure, the exposed surface of the touch insulating layer in the area between two isolated portions can be covered by a passivation layer made of an inorganic insulating material, thereby achieving a structure resistant to moisture penetration.

[0018] In a display device according to an exemplary embodiment of the present disclosure, at least a portion of the lens dam overlaps with at least a portion of the encapsulation dam in the vertical direction, thereby maintaining the height of the lens dam. Therefore, the flow of the fluid insulating material can be controlled to prevent it from flowing to the external area of ​​the display device. Thus, the thickness uniformity of the lens protection member can be ensured to reliably protect the lens.

[0019] Furthermore, according to an exemplary embodiment of this disclosure, the lens dam can be formed in the same process as that used to form the component for adjusting the viewing angle, thereby reducing the number of process steps. Therefore, there is an effect of reducing the production energy required to manufacture the display device and reducing greenhouse gas emissions.

[0020] The effects of this disclosure are not limited to those described above, and other effects not mentioned will be clearly understood by those skilled in the art from the following description.

[0053] In the following description, a display device according to each embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0054] Figure 1 An example of a display device applied to a vehicle according to an exemplary embodiment of the present disclosure is shown.

[0055] Reference Figure 1The display device, including the display panel 10 according to an exemplary embodiment of the present disclosure, can be installed inside a vehicle. For example, the display panel 10 may include a first display area 10a, a second display area 10b, and a third display area 10c. In the example, the first display area 10a may be located in front of the driver's seat, the third display area 10c may be located in front of the passenger seat, and the second display area 10b may be located in the common space between the driver's seat and the passenger seat.

[0056] The first display area 10a can provide information indicating the driving status to the user in the driver's seat on the dashboard. The second display area 10b or the third display area 10c can display navigation or video based on the user's selection or the vehicle's driving status. In this example, when the vehicle is in motion, the viewing angle of the second display area 10b and / or the third display area 10c can be controlled so as not to interfere with the driver's driving. For example, the viewing angle can be controlled so that the image provided from the second display area 10b and / or the third display area 10c is not reflected on the window in the forward and upward directions of the driver's seat, so as not to interfere with the driver's driving.

[0057] Figure 2 This is a plan view of a display device according to an embodiment of the present disclosure. Figure 3 yes Figure 2 A magnified view of region I. For ease of explanation, Figure 3 Only the embankment 265, the embankment hole 265H, and the lens 340 are shown.

[0058] Reference Figure 2 and Figure 3 A display device according to an exemplary embodiment of the present disclosure may include a display panel 10, which includes a display area DA and a non-display area NDA located outside the display area DA. The non-display area NDA may also be referred to as an edge area or a border area.

[0059] Display panel 10 may include a display area DA and a non-display area NDA. The display area DA may be an area for displaying images. The non-display area NDA may be an area for not displaying images. The non-display area NDA may be located in the peripheral area (or edge area) of display panel 10. However, embodiments of this disclosure are not limited thereto. For example, the area remaining outside the light-emitting area that emits light outward in the display area DA may be referred to as the non-display area NDA. The bezel area BZA of the display device may be defined by the non-display area NDA. The bezel area BZA may surround the outside of the display area DA. The bezel area BZA may include a first bezel area BZA1 and a second bezel area BZA2. For example, the first bezel area BZA1 may be located on one side of display panel 10, and the second bezel area BZA2 may be located on three sides of display panel 10, but is not limited thereto. For example, the first bezel area BZA1 may be located at the lower part of display panel 10, and the second bezel area BZA2 may be located at the upper, left, and right parts of display panel 10. The lower part of the display panel 10, which has a first border area BZA1, may be an area where a pad area PDA is provided, and the pad area PDA has multiple pads that are electrically connected to a printed circuit board or a driver circuit chip.

[0060] Multiple pixels P can be set in a display area DA. Each of the multiple pixels P can include multiple sub-pixels. For example, each of the multiple pixels P can include multiple sub-pixels SP1, SP2, and SP3, but is not limited thereto. More or fewer sub-pixels can be included. An image can be displayed using the multiple sub-pixels SP1, SP2, and SP3 in the display area DA. The multiple sub-pixels SP1, SP2, and SP3 can be arranged in an array in the display area DA. In the example, the multiple sub-pixels SP1, SP2, and SP3 can be spaced apart from each other in a first direction DR1 and a second direction DR2 intersecting the first direction DR1 in the display area DA to form a matrix arrangement. In the example, the multiple sub-pixels SP1, SP2, and SP3 of one pixel P can be spaced apart from each other in the first direction DR1. In the example, the multiple sub-pixels SP1, SP2, and SP3 of one pixel P and the multiple sub-pixels SP1, SP2, and SP3 of another pixel P can be spaced apart from each other in the second direction DR2. The first direction DR1 can be a vertical direction, an X-axis direction, or a row direction, and the second direction DR2 can be a horizontal direction, a Y-axis direction, or a column direction. However, the embodiments disclosed herein are not limited thereto, and the arrangement shape, arrangement order and arrangement direction of sub-pixels SP1, SP2 and SP3 can be changed in different ways.

[0061] In this disclosure, a pixel P is configured to include multiple sub-pixels, such as a first sub-pixel SP1, a second sub-pixel SP2, and a third sub-pixel SP3. However, embodiments of this disclosure are not limited thereto. For example, a pixel P may also include additional sub-pixels.

[0062] Subpixels SP1, SP2, and SP3 can be implemented to emit light of the same color, such as white light, or they can be implemented to emit light of different colors, such as red, green, and blue. In another exemplary embodiment, each subpixel can display one of cyan, magenta, and yellow. In various embodiments, each subpixel can display one of red, green, blue, and white. For example, the first subpixel SP1 can emit red light, the second subpixel SP2 can emit green light, and the third subpixel SP3 can emit blue light. However, the embodiments of this disclosure are not limited thereto.

[0063] Various lines and circuits for driving multiple sub-pixels SP1, SP2, and SP3 of the display area DA can be disposed in the non-display area NDA. For example, a driving circuit including a gating driving circuit and a data driving circuit can be disposed in the non-display area NDA. Several drivers for driving the display area DA can be disposed in the non-display area NDA. For example, the drivers may include gating drivers and data drivers. However, embodiments of this disclosure are not limited thereto. The pad area PDA may be disposed in one edge of the non-display area NDA. For example, the pad area PDA may be disposed in the lower part of the display panel 10. However, embodiments of this disclosure are not limited thereto.

[0064] Multiple lens dams 510, 520, and 530 may be disposed in the non-display area NDA, spaced apart from each other. The multiple lens dams 510, 520, and 530 may include a first lens dam 510, a second lens dam 520, and a third lens dam 530. Each of the lens dams 510, 520, and 530 may extend along the shape of the display area DA to surround the exterior of the display area DA. For example, the multiple lens dams 510, 520, and 530 may be configured to extend along the shape of the display area DA within the non-display area NDA. Each of the lens dams 510, 520, and 530 may have a continuous linear shape. For example, each of the lens dams 510, 520, and 530 may have a closed-loop linear shape. (See below for further details.) Figure 9 and Figure 10 This will be described in detail. For example, the second lens dam 520 may be disposed outside the first lens dam 510, and the third lens dam 530 may be disposed outside the second lens dam 520, but is not limited thereto.

[0065] Reference Figure 3Subpixels SP1, SP2, and SP3 can be distinguished from each other by the dam 265. For example, the dam hole 265H, which is the opening area of ​​the dam 265, can constitute the boundary region between adjacent subpixels and can define the light-emitting region EA. The area in each of subpixels SP1, SP2, and SP3 that is not covered by the dam 265 can be the light-emitting region EA. A lens 340, as a viewing angle adjustment member, can be disposed in each of subpixels SP1, SP2, and SP3 and can overlap with the light-emitting region EA. The lens 340 can include a hemispherical lens. However, embodiments of this disclosure are not limited thereto. For example, the lens 340 can include a cylindrical lens. In the example, the lens 340 can be used to prevent unwanted screen visibility to the user. The lens 340 can be referred to as a component for adjusting the viewing angle. Reference will be made later. Figure 5 and Figure 6 This will be described.

[0066] An example implementation of a subpixel will be described below.

The pixel driving circuit may be disposed on the substrate 205, and the light-emitting element 285 may be disposed on the pixel driving circuit. The pixel driving circuit may include, but is not limited to, a driving transistor, one or more switching transistors, and a capacitor. In the example, the transistor TR may be a driving transistor. However, embodiments of this disclosure are not limited thereto.

A first buffer layer 210 may be disposed on substrate 205. The first buffer layer 210 may cover the surface of substrate 205. For example, the first buffer layer 210 may completely cover the surface of substrate 205. The first buffer layer 210 may reduce or prevent moisture, oxygen, or impurities from penetrating substrate 205. The first buffer layer 210 may be a single layer or multiple layers made of an inorganic insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx).

[0071] A light-shielding layer 215 may be disposed on the first buffer layer 210. The light-shielding layer 215 may be configured to overlap with the transistor TR in the vertical direction. The light-shielding layer 215 can prevent external light from incident on the transistor TR. For this purpose, the light-shielding layer 215 may include an opaque metallic material. A second buffer layer 220 may be disposed on the light-shielding layer 215. The second buffer layer 220 may be disposed on the entire surface of the substrate 205. For example, the second buffer layer 220 may be disposed on the light-shielding layer 215 and the surface of the first buffer layer 210 exposed by the light-shielding layer 215. The second buffer layer 220 can protect the transistor TR from moisture, oxygen, or impurities. The second buffer layer 220 may be a single layer or multiple layers made of an inorganic insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx). However, embodiments of this disclosure are not limited thereto.

The semiconductor layer 225 may include a channel region and a source / drain region. The region of the semiconductor layer 225 that overlaps with the gate 235 in the vertical direction can be the channel region. The source / drain regions can be disposed on two opposite sides of the channel region CH, respectively. The semiconductor layer 225 may be one or a combination of an oxide semiconductor layer, a polysilicon semiconductor layer, and a low-temperature polysilicon semiconductor layer. The semiconductor layer 225 may be configured to overlap with a light-shielding layer 215 in the vertical direction. The light-shielding layer 215 prevents external light from incident on the semiconductor layer 225.

[0073] A gate insulating layer 230 may be disposed between the semiconductor layer 225 and the gate 235. The gate insulating layer 230 is an insulating layer used to insulate the semiconductor layer 225 and the gate 235 from each other. The gate insulating layer 230 may cover the semiconductor layer 225. The gate insulating layer 230 may be a single layer or multiple layers made of silicon oxide (SiOx) or silicon nitride (SiNx). The gate insulating layer 230 may extend into the non-display area NDA. The combination of the first buffer layer 210, the second buffer layer 220, and the gate insulating layer 230 extending into the non-display area NDA may be referred to as the first insulating structure 211.

The gate 235 may be a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or their alloys. However, its material is not limited to these.

[0075] The first intermediate electrode layer 236 may be disposed on the gate insulating layer 230. The first intermediate electrode layer 236 may be disposed in a region different from the region where the gate 235 is disposed. The first intermediate electrode layer 236 may be made of the same material as the gate 235 and may be formed in the same process as that used to form the gate 235, but is not limited thereto. The first intermediate electrode layer 236 may serve as one of the signal lines for transmitting various signals. In an example, the first intermediate electrode layer 236 may extend from the display area DA through the bezel areas BZA1 and BZA2 to the pad area PDA. For example, the region where the first intermediate electrode layer 236 is disposed may be where the driver circuit chip DIC is disposed (see...). Figure 2 (area).

[0076] The first intermediate electrode layer 236 may be a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or their alloys. However, its material is not limited to these.

For example, the first interlayer insulating layer 237 may be disposed on the gate 235 and the first intermediate electrode layer 236, as well as on the portion of the gate insulating layer 230 exposed by the gate 235 and the first intermediate electrode layer 236, but is not limited thereto. The first interlayer insulating layer 237 may be a single layer or multiple layers made of an inorganic insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0079] The second intermediate electrode layer 238 can be disposed on the first interlayer insulating layer 237. The second intermediate electrode layer 238 can be disposed in a region different from the region where the transistor TR is disposed. For example, the second intermediate electrode layer 238 can be configured to overlap the first intermediate electrode layer 236 in the vertical direction, with the first interlayer insulating layer 237 interposed therebetween.

[0080] The second intermediate electrode layer 238 may include a metallic material. The second intermediate electrode layer 238 may be made of the same material as the first intermediate electrode layer 236, but is not limited thereto. For example, the second intermediate electrode layer 238 may be a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof. However, embodiments of this disclosure are not limited thereto. In examples, the second intermediate electrode layer 238 may be used to transmit various signals from a driver circuit chip DIC (see [link to DIC]). Figure 2 Multiple lines, either from the display area DA or from a driver mounted on a printed circuit board, can transmit signals to the display area DA. For example, various signals may include high-potential voltages, low-potential voltages, scan signals, data signals, touch drive signals, etc. However, embodiments of this disclosure are not limited thereto. In an example, the second intermediate electrode layer 238 can extend from the display area DA through the bezel areas BZA1 and BZA2 to the pad area PDA. For example, the area where the second intermediate electrode layer 238 is disposed may be where the driver circuit chip DIC (see [link to relevant documentation]) is disposed. Figure 2 (area).

[0081] A second interlayer insulating layer 239 may be disposed on the second intermediate electrode layer 238 and the first interlayer insulating layer 237. The second interlayer insulating layer 239 may have a plurality of contact holes 243 formed therein. The plurality of contact holes 243 may extend through the second interlayer insulating layer 239, the first interlayer insulating layer 237, and the gate insulating layer 230 to contact portions of the surfaces of the source / drain regions of the semiconductor layer 225, respectively. A portion of the contact holes 243 may be configured to overlap with the via electrode 223 in the vertical direction. The second interlayer insulating layer 239 may be made of the same material as, but is not limited to, the material of the first interlayer insulating layer 237. The second interlayer insulating layer 239 may be embodied as a single layer or multiple layers made of an inorganic insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited to.

[0082] Source / drain 245 may be disposed on the second interlayer insulating layer 239. Source / drain 245 may be disposed in contact via 243. Source / drain 245 may extend through the second interlayer insulating layer 239, the first interlayer insulating layer 237, and the gate insulating layer 230 to connect to the source / drain regions of the semiconductor layer 225, respectively. One of the source / drain 245 may be connected to the via electrode 223 and thus to the light-shielding layer 215. Each of the source / drain 245 may be embodied as a single layer or multiple layers made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or alloys thereof.

[0083] A planarization layer 250 may be disposed on the source / drain 245 and the second interlayer insulating layer 239. The planarization layer 250 can flatten steps caused by the pixel driving circuitry beneath it. The planarization layer 250 may be formed as a structure in which multiple planarization layers are stacked in a vertical direction. For example, in the figures, the planarization layer 250 has a structure in which a first planarization layer 251 and a second planarization layer 252 are stacked in a vertical direction. The first planarization layer 251 may be disposed on the source / drain 245 and the second interlayer insulating layer 239, and the second planarization layer 252 may be disposed on the first planarization layer 251. However, embodiments of this disclosure are not limited thereto. For example, embodiments of this disclosure may include a multilayer structure in which a third planarization layer (not shown) is further stacked on the second planarization layer 252. However, embodiments of this disclosure are not limited thereto. For example, the planarization layer 250 may be formed as a single layer. For example, the planarization layer 250 may include an organic insulating material such as polyimide or acrylic resin.

[0084] The first planarization layer 251 and the second planarization layer 252 may be formed from one or more materials selected from acrylic resin, epoxy resin, phenolic resin, polyamide resin, unsaturated polyester resin, polyphenylene resin, polyphenylene sulfide resin and benzocyclobutene, but the embodiments are not limited thereto.

[0085] The light-emitting element 285 can be formed on the planarization layer 250. For example, the light-emitting element 285 can be disposed on the second planarization layer 252. The light-emitting element 285 may include a first electrode 260, a light-emitting layer 270, a second electrode 275, and a capping layer 280, but the implementation is not limited thereto.

[0086] The light-emitting element 285 can be electrically connected to the pixel driving circuit via the first electrode 260. For example, a pixel contact hole 255 can be formed in the planarization layer 250. The pixel contact hole 255 can pass through the planarization layer 250, the second interlayer insulating layer 239, the first interlayer insulating layer 237, and the gate insulating layer 230. The pixel contact hole 255 can expose a portion of the surface of the other of the source / drain electrodes 245.

[0087] The first electrode 260 of the light-emitting element 285 can be electrically connected to the other of the source / drain 245 via the pixel contact hole 255. The first electrode 260 can be disposed on and in contact with the pixel contact hole 255 so as to be connected to the other of the source / drain 245 via the pixel contact hole. The light-emitting layer 270, the second electrode 275, and the capping layer 280 are stacked in the vertical direction.

[0088] The first electrode 260 may include a transparent conductive layer. The first electrode 260 may include ITO (indium tin oxide) or IZO (indium zinc oxide). Alternatively, the first electrode 260 may have a single-layer or multi-layer structure, comprising a reflective metallic film made of one of silver (Ag), aluminum (Al), gold (Au), nickel (Ni), and chromium (Cr), or an alloy thereof. The first electrode 260 may also be referred to as an anode electrode or a pixel electrode.

[0089] A dam 265 may be disposed on the first electrode 260. The dam 265 may be configured to cover the edge of the first electrode 260. A portion of the dam 265 may extend onto the planarization layer 250. In an example, the dam 265 may fill the remainder of the trench except for the portion that fills the pixel contact hole 255. The dam 265 may have a dam hole 265H defined therein as an opening exposing a portion of the upper surface of the first electrode 260. The portion of the upper surface of the first electrode 260 not covered by the dam 265 and exposed through the dam hole may be a light-emitting region EA. The dam 265 may be made of an organic insulating material. The dam 265 may include, for example, photosensitive polyimide, photoacryloyl, or benzocyclobutene (BCB). In an example, the dam 265 may include a black material, a light-blocking material, or a light-absorbing material. The dam 265 may include a material that absorbs light within a specific wavelength range. The embankment 265 may have a structure in which at least two color filters of different colors, including red, green and blue, are stacked.

[0090] The light-emitting layer 270 may be disposed on the first electrode 260. For example, the light-emitting layer 270 may be disposed on the first electrode 260 and the embankment 265. The light-emitting layer 270 may include a hole transport layer (HTL), an organic light-emitting layer (EML), an electron transport layer (ETL), a hole blocking layer (HBL), a hole injection layer (HIL), an electron blocking layer (EBL), and an electron injection layer (EIL). The light-emitting layer 270 may have a multilayer stacked structure in which two or more organic light-emitting layers (EML) are stacked.

[0091] The second electrode 275 can be disposed on the light-emitting layer 270. The second electrode 275 can be formed over the entire surface of the substrate 205 to connect collectively to the light-emitting layer 270 formed in all sub-pixels. Therefore, the second electrode 275 can also be referred to as a cathode electrode or a common electrode. The second electrode 275 can include a transmissive and reflective conductive material. For example, the second electrode 275 can include a metallic material, such as magnesium (Mg), silver (Ag), or an alloy of silver (Ag) and magnesium (Mg) (Ag-Mg). In an example, the second electrode 275 can include a transparent conductive layer made of, for example, indium tin oxide (ITO) or indium zinc oxide (IZO).

[0092] A capping layer 280 may be disposed on the second electrode 275. The capping layer 280 can correct optical properties by preventing the loss of light generated from the light-emitting layer 270.

[0093] The encapsulation portion 290 can be provided on the light-emitting element 285. For example, the encapsulation portion 290 can be provided on the cover layer 280. The encapsulation portion 290 can protect the light-emitting element 285 from external oxygen or moisture. The encapsulation portion 290 can cover the display area DA and extend into the non-display area NDA.

[0094] The encapsulation portion 290 may include a single layer or a multilayer structure in which multiple encapsulation layers are stacked. The encapsulation portion 290 may include a multilayer structure in which a first encapsulation layer 291, a second encapsulation layer 292, and a third encapsulation layer 293 are stacked, but the implementation is not limited thereto. The second encapsulation layer 292 may be disposed between the first encapsulation layer 291 and the third encapsulation layer 293. More or fewer encapsulation layers may be included.

[0095] A first encapsulation layer 291 may be disposed on the light-emitting element 285. The first encapsulation layer 291 may be disposed on the cover layer 280. A second encapsulation layer 292 may be disposed on the first encapsulation layer 291. The second encapsulation layer 292 may cover the first encapsulation layer 291 and may have sufficient thickness to have a flat upper surface. The second encapsulation layer 292 may prevent foreign objects from entering the light-emitting element 285. A third encapsulation layer 293 may be disposed on the second encapsulation layer 292.

[0096] Inorganic insulating materials may be included in each of the first encapsulation layer 291 and the third encapsulation layer 293. For example, each of the first encapsulation layer 291 and the third encapsulation layer 293 may include at least one of silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxynitride (SiON). Organic insulating materials may be included in the second encapsulation layer 292. For example, the second encapsulation layer 292 may include at least one of epoxy resin, polyimide, polyethylene, and acrylate.

[0097] The touch sensing unit can be disposed on the package 290 and includes a touch sensor and a touch insulating layer. A plurality of lenses 340 can be disposed on the touch sensing unit. The touch sensing unit may include, but is not limited to, a first touch buffer layer 295, a touch sensor 330, a second touch buffer layer 305, a light-shielding pattern 310, a touch insulating layer 315, and a passivation layer 335.

[0098] A first touch buffer layer 295 may be disposed on the third encapsulation layer 293. The first touch buffer layer 295 may include an inorganic insulating material. For example, the first touch buffer layer 295 may include silicon nitride (SiNx). The first touch buffer layer 295 can alleviate stress between the encapsulation portion 290 and the touch sensor 330.

[0099] The touch sensor 330 may include a plurality of touch electrodes 325 and a plurality of bridging electrodes 300. For example, the touch sensor 330 may be disposed on a first touch buffer layer 295. The plurality of touch electrodes 325 and the plurality of bridging electrodes 300 may be disposed in different layers. For example, the plurality of bridging electrodes 300 may be disposed on the first touch buffer layer 295. The plurality of touch electrodes 325 may be disposed on a touch insulating layer 315.

[0100] The touch sensor 330 may also include multiple touch lines for electrically connecting the multiple touch electrodes 325 to the touch driving circuitry. The touch sensor 330 may be implemented as a touch panel external to the display panel 10 or integrated inside the display panel 10. The touch driving circuitry may provide a touch driving signal to at least one of the multiple touch electrodes 325 and sense at least one of the multiple touch electrodes 325 to generate touch sensing data.

[0101] Touch sensing circuits can perform touch sensing. For example, touch sensing circuits can perform touch sensing using self-capacitance sensing technology or mutual capacitance sensing technology, but are not limited to these.

[0102] In an example where the touch sensing circuit performs touch sensing using self-capacitance sensing technology, the touch sensing circuit can perform touch sensing based on the capacitance between each touch electrode and the touch object (e.g., a finger, a pen, etc.).

[0103] In an example where the touch sensing circuit performs touch sensing using mutual capacitance sensing technology, the touch sensing circuit can perform touch sensing based on the capacitance between the touch electrodes.

[0104] Each of the plurality of touch electrodes 325 or the plurality of bridging electrodes 300 may be embodied as a single layer or multiple layers made of any of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or alloys thereof. For example, each of the plurality of touch electrodes 325 or the plurality of bridging electrodes 300 may be a stacked structure of titanium layer / aluminum layer / titanium layer (Ti / Al / Ti), but is not limited thereto.

[0105] A second touch buffer layer 305 may be disposed on the plurality of bridging electrodes 300 and the first touch buffer layer 295. A touch insulating layer 315 may be disposed between adjacent touch electrodes among the plurality of touch electrodes 325 and between adjacent bridging electrodes among the plurality of bridging electrodes 300. A light-shielding pattern 310 may be disposed on the second touch buffer layer 305. The plurality of touch electrodes 325 may be disposed on the touch insulating layer 315 and spaced apart from each other. The bridging electrodes 300 may electrically connect adjacent touch electrodes 325 to each other. For this purpose, each touch electrode 325 may extend through the touch insulating layer 315, the light-shielding pattern 310 and the second touch buffer layer 305 to be electrically connected to the bridging electrode 300. Adjacent touch electrodes 325 may be electrically insulated from each other by a passivation layer 335.

[0106] Inorganic insulating material may be included in the second touch buffer layer 305 or passivation layer 335. For example, the second touch buffer layer 305 or passivation layer 335 may be made of an inorganic insulating material including silicon nitride (SiNx).

[0107] The touch insulating layer 315 can diffuse or converge light generated from the light-emitting element 285, such that the diffused or converged light is guided to the lens 340. For this purpose, the touch insulating layer 315 can be formed to have a sufficient thickness. It may be difficult to implement an inorganic insulating material layer as the touch insulating layer 315 to have the required thickness. Therefore, the touch insulating layer 315 may include an organic insulating material. For example, the touch insulating layer 315 may include organic insulating materials such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, or polyimide resin. However, its material is not limited to these.

[0108] A light-shielding pattern 310 can be disposed on the second touch buffer layer 305. The light-shielding pattern 310 can prevent color mixing between light beams from adjacent light-emitting elements 285. In addition, the light-shielding pattern 310 can block light from the outside or light reflected from the outside. Therefore, the brightness of the display device can be further improved.

[0109] Therefore, the light-shielding pattern 310 may include an opaque material. For example, the light-shielding pattern 310 may include an organic insulating material, which may include a black pigment or a black dye. In examples, the organic insulating material may include organic materials such as benzocyclobutene resin, epoxy resin, polyimide resin, acrylic resin, or photosensitive polymer. However, embodiments of this disclosure are not limited thereto.

[0110] Multiple opening regions 313 may be provided in the light-shielding pattern 310. In the example, at least a portion of the opening region 313 may be configured to overlap with the light-emitting region EA of the light-emitting element 285. In the example embodiment, one opening region 313 defined in the light-shielding pattern 310 may overlap with the light-emitting region EA of a sub-pixel SP. However, embodiments of this disclosure are not limited thereto.

[0111] Multiple lenses 340 may be disposed on the passivation layer 335. Adjacent lenses 340 may be arranged to be spaced apart from each other by a predetermined distance. In the example, a lens 340 may be configured to overlap with an opening region 313 defined in the light-shielding pattern 310, but is not limited thereto.

[0112] Lens 340 may include an organic insulating material. For example, lens 340 may include an organic insulating material having a second density that is relatively higher than the first density of touch insulating layer 315. The organic insulating material having a second density that is relatively higher than the first density of touch insulating layer 315 can prevent moisture from penetrating therein.

[0113] Lens 340 may be a hemispherical lens that overlaps with the opening region 313 in the vertical direction. For example, lens 340 may have a hemispherical shape with a convex surface protruding toward the lens protective layer 350. For example, the convex surface of lens 340 may contact the lens protective layer 350. The light-receiving surface of lens 340 facing the protruding convex surface and receiving light generated from the light-emitting element 285 may be a flat surface. The light-receiving surface of lens 340 may contact the passivation layer 335.

[0114] Light generated from the light-emitting element 285 and passing through the opening region 313 can be provided to the light-receiving surface of the lens 340 and refracted by the convex surface of the lens 340 to be emitted to the outside. Light beams emitted from the light-emitting element 285 in various directions can undergo changes in their travel path through the lens 340 to converge in the forward direction. Therefore, the viewing angle of the display device can be controlled.

[0115] like Figure 5 and Figure 6 As shown, lens 340 may include at least one of a first lens 340-1 or a second lens 340-2. The first lens 340-1 and the second lens 340-2 may have different shapes.

[0116] For example, refer to Figure 5The first lens 340-1 may have a rectangular bottom surface and, in a cross-sectional view, a hemispherical cylindrical shape with hemispherical side surfaces. In the rectangular bottom surface of the first lens 340-1, the light travel of light emitted from a width region of a sub-pixel may not be restricted in the first direction X-X' (or row direction), while the light travel of light emitted from a width region of a sub-pixel may be restricted in the second direction Y-Y' (or column direction), as indicated by the label "X". Therefore, light traveling in the vertical direction can be restricted, thereby controlling the viewing angle in the vertical direction.

[0117] In addition, refer to Figure 6 The second lens 340-2 can have a circular bottom surface and can also have a hemispherical shape. Therefore, in the circular bottom surface of the second lens 340-2, the light travel of light emitted from the width region of a sub-pixel can be restricted in a first direction X-X' (or row direction) indicated by the mark "X", while the light travel of light emitted from the width region of a sub-pixel can be restricted in a second direction Y-Y' (or column direction) indicated by the mark "X". When the display device is installed in a vehicle, the light travel along each of the vertical and horizontal directions can be restricted, thus restricting the viewing angle in each of the vertical and horizontal directions of the display device. Therefore, when the second lens 340-2 is used in a display device in front of the driver's seat, the image from it can be recognized solely by the driver in the driver's seat. Furthermore, when the second lens 340-2 is used in a display device in front of the passenger seat, the image from it can be recognized solely by the passenger in the passenger seat.

[0118] Reference Figure 7 and Figure 8 One or more display areas 10a and 10b may be provided in the vehicle. At least one display area 10a and 10b may include a first display area 10a and a second display area 10b. Furthermore, although not shown in the accompanying drawings, a third display area 10c may be provided in front of the passenger seat (see [reference]). Figure 1 ).

[0119] Reference Figure 7 The viewing angle adjustment component may not be located in the display panel provided in the second display area 10b, which is situated between the first display area 10a and the third display area 10c among display areas 10a to 10c. Then, the image or image IMG1 provided from the second display area 10b can be reflected in the front-rear direction onto the first position 20a of the front glass 20. The image IMG1 reflected onto the first position 20a may interfere with the user's (or driver's) field of vision. In this regard, as... Figure 8As shown, when the view adjustment component (such as...) Figure 5 and Figure 6 When the lens shown is placed in the display panel disposed in the second display area 10b, it can limit light traveling in the vertical and / or horizontal directions, thereby limiting the viewing angle of the display panel disposed in the second display area 10b in the vertical and / or horizontal directions. Therefore, the image IMG1 may not be reflected onto the first position 20a. Thus, when the driver is driving the vehicle, the driver's field of vision can be prevented from being obstructed.

[0120] A lens protection layer 350 can be disposed on the lens 340. A polarizing layer 360 can be disposed on the lens protection layer 350. The lens protection layer 350 can protect the lens 340 disposed beneath it from external foreign objects or the like. The lens protection layer 350 can be referred to as a lens protection member. Furthermore, the lens protection layer 350 can flatten the step created by the lens 340. The lens protection layer 350 can extend from the display area DA to a portion of the bezel areas BZA1 and BZA2. In this example, the refractive index of the lens protection layer 350 can be lower than that of the lens 340. Therefore, light that has passed through the lens 340 can be prevented from being directed toward the substrate 205.

[0121] A fluid insulating material may be included in the lens protective layer 350. The lens protective layer 350 may include a fluid insulating material and is thus formed to have an upper flat surface in the display area DA. An organic insulating material may be included in the fluid insulating material. For example, the organic insulating material may include at least one of epoxy resin, polyimide, polyethylene, and acrylate. However, the material is not limited to these.

[0122] When the fluid insulating material flows to the outer area (or edge area) of the display panel 10, the height of the portion of the lens protection layer 350 disposed in the portion of the display area DA closer to the bezel areas BZA1 and BZA2 may be reduced. As a result, the height uniformity between the portion of the lens protection layer 350 in the central region of the display area DA and the portion of the lens protection layer 350 in the portion of the display area DA closer to the bezel areas BZA1 and BZA2 may deteriorate.

[0123] Therefore, display devices according to some embodiments of the present disclosure may include structures for controlling the flow of an insulating material having fluidity in the bezel region. Furthermore, display devices according to embodiments of the present disclosure may include structures capable of preventing moisture penetration into the display area. This will be described below with reference to the accompanying drawings.

Figure 9 It is along Figure 2 The cross-sectional view taken from line III-III'. Figure 10 yes Figure 9 A magnified view of region V. Figure 11 It is along Figure 2 A cross-sectional view taken from line IV-IV'.

[0125] For example, Figure 9 The settings on display panel 10 can be shown (see...) Figure 2 The cross-section of a portion of the display area DA and the non-display area NDA on one side of the second direction DR2. Figure 11 A cross-section can be shown of a portion of the display area DA and the non-display area NDA disposed on the other side of the second direction DR2 and on each of the two opposite sides of the first direction DR1 of the display panel. Figure 10 For ease of explanation, the polarization layer 360 is excluded. Because... Figures 9 to 11 Including with Figure 4 The same components will be omitted or briefly described, and the differences between them will be the main focus. The same reference numerals may denote the same elements.

[0126] Reference Figures 9 to 11 The first insulating structure 211 may be disposed on the substrate 205 and in the non-display area NDA. The first insulating structure 211 may include one or more insulating layers extending from the display area DA. For example, the first insulating structure 211 may include a first buffer layer 210, a second buffer layer 220, and a gate insulating layer 230. The first insulating structure 211 may be embodied as a single layer or multiple layers made of inorganic insulating materials such as silicon oxide (SiOx) or silicon nitride (SiNx). However, embodiments of this disclosure are not limited thereto.

[0127] The first intermediate electrode layer 236 may be disposed on the first insulating structure 211 and in the non-display area NDA. In the example, the first intermediate electrode layer 236 may serve as one of the signal lines for transmitting various signals. In this disclosure, for ease of description, an example embodiment in which the first intermediate electrode layer 236 is made of the same material as the gate 235 and formed in the same process as the process used to form the gate 235 will be described, but it is not limited thereto. For example, the first intermediate electrode layer 236 may be made of a different material than the gate 235 and may be formed in a different process than the process used to form the gate 235. Furthermore, in this disclosure, for ease of description, an example embodiment in which the first intermediate electrode layer 236 is embodied as a single layer has been described. However, the embodiments of this disclosure are not limited thereto. For example, the first intermediate electrode layer 236 may be embodied as a stack of multiple layers.

[0128] A first interlayer insulating layer 237 may be disposed on the first intermediate electrode layer 236 and in the non-display area NDA. The first interlayer insulating layer 237 may include an inorganic insulating material and may extend from the display area DA. A second intermediate electrode layer 238 may be disposed on the first interlayer insulating layer 237 and in the non-display area NDA. The second intermediate electrode layer 238 may be used as, for example, one of the signal lines for transmitting various signals. The second intermediate electrode layer 238 may extend into the pad area PDA.

[0129] The second interlayer insulating layer 239 can be disposed on the second intermediate electrode layer 238 and in the non-display area NDA. Signal line 245i can be disposed on the second interlayer insulating layer 239. Signal line 245i can be made of the same material as the source / drain 245 and can be disposed in conjunction with the material used to form the source / drain 245 (see...). Figure 4 The pad electrode 245p, made of the same material as the signal line 245i and formed by the same process used to form the signal line 245i, can be disposed in the pad area PDA. The pad electrode 245p can contact and be electrically connected to the second intermediate electrode layer 238. Although not shown in the figure, the pad electrode 245p can be connected to the printed circuit board via a flexible circuit board on which a driver circuit chip is disposed. Therefore, the second intermediate electrode layer 238 can provide the display area DA with power or data signals supplied from the driver disposed on the printed circuit board for driving the light-emitting elements.

[0130] A planarization layer 250 can be disposed on signal line 245i. The planarization layer 250 can be disposed in a portion of the border regions BZA1 and BZA2 and the display region DA. For example, a portion of the planarization layer 250 can be used as a pad protection pattern 250p covering one side end of the pad electrode 245p. A first electrode 260 extending from the display region DA can be disposed on the planarization layer 250 and in the non-display region NDA. The first electrode 260 can extend into a portion of the border regions BZA1 and BZA2. A dam 265 can be disposed on the first electrode 260 and in the non-display region NDA. The dam 265 can extend into a portion of the border regions BZA1 and BZA2.

[0131] Multiple blocking patterns 267i, 265i, and 250b can be provided in the border areas BZA1 and BZA2. Furthermore, multiple first structures, such as multiple encapsulation dams 400, can also be provided in the border areas BZA1 and BZA2.

[0132] The bezel regions BZA1 and BZA2 may include a first bezel region BZA1 and a second bezel region BZA2. For example, the first bezel region BZA1 may be located on one side of the display panel 10, and the second bezel region BZA2 may be located on three sides of the display panel 10, but is not limited thereto. For example, as... Figure 2 As shown, the first bezel region BZA1 can be located on one side of the display panel 10 in the second direction DR2. The second bezel region BZA2 can be located on each of the other sides of the display panel 10 in the second direction DR2 and on each of the two opposite sides in the first direction DR1. For example, a pad region PDA in which a plurality of pad electrodes 245p are provided can be located in the first bezel region BZA1, but is not limited thereto.

[0133] Each of the border regions BZA1 and BZA2 may include a first region A1, a second region A2, and a third region A3. The first region A1 of the border regions BZA1 and BZA2 may be the region closest to the display region DA among the first to third regions. The third region A3 of the border regions BZA1 and BZA2 may be the region closest to the edge (or end) of the substrate 205 among the first to third regions. For example, as... Figure 9 As shown, the third region A3 of the first border region BZA1 can be closer to the pad region PDA than either the first region A1 or the second region A2. Figure 11 As shown, the third region A3 of the second border region BZA2 can be the region closest to the end of the substrate 205 among the first to third regions. The second region A2 can be located between the first region A1 and the third region A3.

[0134] Multiple barrier patterns 267i, 265i and 250b and multiple encapsulation dams 400 can prevent the second encapsulation layer 292, which includes organic insulating material, from overflowing from the border areas BZA1 and BZA2.

[0135] Multiple blocking patterns 267i, 265i, and 250b may include a first blocking pattern 267i, a second blocking pattern 265i, and a third blocking pattern 250b. The first blocking pattern 267i may be located on the embankment 265 and disposed in the first region A1 closest to the display area DA. The first blocking pattern 267i may be made of the same material as the spacer 267 and may be connected to the spacer 267 used to form the display area DA (see [link to documentation]). Figure 4 The process is the same as, but not limited to, the process.

[0136] The plurality of encapsulation dams 400 may include a first encapsulation dam 410, a second encapsulation dam 420, and a third encapsulation dam 430. The first encapsulation dam 410, the second encapsulation dam 420, and the third encapsulation dam 430 may be arranged to be spaced apart from each other by a predetermined distance in a direction from a first region adjacent to the display region DA of the bezel regions BZA1 and BZA2 to the side end of the substrate 205 or the display panel. The second encapsulation dam 420 may be disposed between the first encapsulation dam 410 and the third encapsulation dam 430.

[0137] The first encapsulation dam 410 can be disposed in the boundary region between the first region A1 and the second region A2. For example, the first encapsulation dam 410 can be disposed in the second region A2 and in the boundary region between the first region A1 and the second region A2. The first encapsulation dam 410 can have a structure in which a first layer 265a as the lower layer and a second layer 267a as the upper layer are stacked. For example, the first layer 265a can be made of the same material as the dam 265 and can be formed in the same process as the process used to form the dam 265, but is not limited thereto. The second layer 267a can be made of the same material as the first barrier pattern 267i and can be formed in the same process as the process used to form the first barrier pattern 267i, but is not limited thereto.

[0138] For example, the first layer 265a may be made of a material different from that of the embankment 265, and may be formed in a process different from that used to form the embankment 265, but is not limited thereto. The second layer 267a may be made of a material different from that of the first barrier pattern 267i, and may be formed in a process different from that used to form the first barrier pattern 267i.

[0139] The second blocking pattern 265i can be disposed in the first region A1. For example, the second blocking pattern 265i can be disposed between the first encapsulation dam 410 and the first blocking pattern 267i. The second blocking pattern 265i can be made of the same material as the dam 265 and can be formed in the same process as that used to form the dam 265. In the example, the second blocking pattern 265i can be configured such that multiple patterns are spaced apart from each other.

[0140] The third encapsulation dam 430 can be disposed in the boundary region between the second region A2 and the third region A3 of the border regions BZA1 and BZA2. For example, the third encapsulation dam 430 can be disposed in the second region A2 and in the boundary region between the second region A2 and the third region A3 of the border regions BZA1 and BZA2. When the third encapsulation dam 430 is disposed between the end of the first encapsulation dam 410 and the substrate 205, the third encapsulation dam 430 can be spaced apart from the first encapsulation dam 410. The third encapsulation dam 430 can have a structure in which a first layer 250a as the lower layer and a second layer 265c as the upper layer are stacked. For example, the first layer 250a of the third encapsulation dam 430 can be made of the same material as the planarization layer 250 and can be formed in the same process as the process used to form the planarization layer 250, but is not limited thereto. The second layer 265c of the third encapsulation dam 430 can be made of the same material as the dam 265 and can be formed in the same process as the process used to form the dam 265, but is not limited thereto.

[0141] The second encapsulation dam 420 may be disposed in the second region A2. The second encapsulation dam 420 may be disposed between the first encapsulation dam 410 and the third encapsulation dam 430. The second encapsulation dam 420 may include a plurality of patterns 265b1 and 265b2 spaced apart from each other in the horizontal direction. The plurality of patterns 265b1 and 265b2 may be made of the same material as the dam 265 and may be formed in the same process as the process used to form the dam 265, but are not limited thereto. The plurality of patterns 265b1 and 265b2 may include a first pattern 265b1 and a second pattern 265b2. However, embodiments of the present disclosure are not limited thereto, and may include at least three patterns. Each of the first pattern 265b1 and the second pattern 265b2 may have a line extending along the periphery of the display region DA and surrounding the display region DA. The second pattern 265b2 may be located outside the first pattern 265b1, and the second pattern 265b2 may be located inside the third encapsulation dam 430.

[0142] The third blocking pattern 250b can be disposed on the outer side of the third package dam 430. For example, the third blocking pattern 250b can be disposed in the third region A3 as the edge region of the border regions BZA1 and BZA2. The third blocking pattern 250b can be made of the same material as the planarization layer 250 and can be formed by the same process as that used to form the planarization layer 250, but is not limited thereto. The third blocking pattern 250b can cover the ends of the signal line 245i that extend into the border regions BZA1 and BZA2.

[0143] Each of the first encapsulation layer 291, the second encapsulation layer 292, and the third encapsulation layer 293 can extend from the display area DA into the bezel areas BZA1 and BZA2. The first encapsulation layer 291 can cover the first blocking pattern 267i, the second blocking pattern 265i, the first encapsulation dam 410, the second encapsulation dam 420, and the third encapsulation dam 430. The third encapsulation layer 293 can be disposed on the second encapsulation layer 292 in the first area A1 of the bezel areas BZA1 and BZA2, and can contact the first encapsulation layer 291 in the second area A2 and the third area A3. Inorganic insulating material can be included in each of the first encapsulation layer 291 and the third encapsulation layer 293. The second encapsulation layer 292 can be disposed between the first encapsulation layer 291 and the third encapsulation layer 293. For example, in the first area A1 of the bezel areas BZA1 and BZA2, the second encapsulation layer 292 can be disposed between the first encapsulation layer 291 and the third encapsulation layer 293, but is not limited thereto.

[0144] The first touch buffer layer 295 may be disposed on the third encapsulation layer 293 and in the non-display area NDA. The first touch buffer layer 295 may include an inorganic insulating material.

[0145] Multiple bridging electrodes 300 can be disposed on the first touch buffer layer 295. Some areas of the multiple bridging electrodes 300 can extend into the border areas BZA1 and BZA2, and then into the pad area PDA. The portion of the bridging electrodes 300 extending into the pad area PDA can be referred to as a bridge link 300a. The bridge link 300a can contact and be electrically connected to the pad electrode 245p in the pad area PDA. The bridge link 300a can transmit touch drive signals from the drive circuit chip or driver disposed on the printed circuit board to the display area DA. Therefore, the bridge link 300a can be used as... Figure 9 The display panel DP is positioned on one side of the first direction DR1, as shown, and can be configured as follows: Figure 11 The diagram shows that the display panel DP is not positioned on the other side of the first direction DR1 and on each of the two opposite sides of the second direction DR2.

[0146] The second touch buffer layer 305 may be disposed on a plurality of bridging electrodes 300 and bridging links 300a. The second touch buffer layer 305 may extend into the border regions BZA1 and BZA2, simultaneously covering the plurality of bridging electrodes 300 and bridging links 300a. The second touch buffer layer 305 may be conformally formed on each of the first touch buffer layer 295 and the third encapsulation layer 293 disposed below it. The second touch buffer layer 305 may cover the bridging links 300a disposed in the pad region of the PDA. The second touch buffer layer 305 may include an inorganic insulating material.

[0147] A touch insulating layer 315 can be disposed on the second touch buffer layer 305 and in the non-display area NDA. The touch insulating layer 315 can extend from the display area DA into the border areas BZA1 and BZA2. The side ends of the touch insulating layer 315 extending into the border areas BZA1 and BZA2 can be implemented as inclined surfaces 315i with bevels. Furthermore, in the first border area BZA1, the side ends of the touch insulating layer 315 can define the boundary region between the third area A3 and the pad area PDA. Furthermore, in the second border area BZA2, the side ends of the touch insulating layer 315 can be located inside the side ends of the substrate 205. For example, the side ends of the touch insulating layer 315 can be located in the third area A3 of the border areas BZA1 and BZA2.

[0148] The touch insulating layer 315 may have sufficient thickness to flatten the steps caused by the underlying structure. The touch insulating layer 315 may include an organic insulating material. At least one trench 315t may be defined in the touch insulating layer 315. The trench 315t may extend vertically through the touch insulating layer 315 in a direction toward the substrate 205 and may expose a portion of the upper surface of the second touch buffer layer 305. In a cross-sectional view, the trench 315t may have a columnar shape extending vertically through the touch insulating layer 315. The trench 315t may be configured to overlap with a first encapsulation dam 410 of a plurality of encapsulation dams 400 in a vertical direction. In a plan view, the trench 315t may have an annular shape surrounding the outer periphery of the display area DA. For example, the trench 315t may have a closed-loop linear shape in a plan view.

[0149] Multiple touch electrodes 325 can be disposed on the touch insulating layer 315 and in the display area DA. A passivation layer 335 can be disposed on the touch electrodes 325 and in the non-display area NDA. The passivation layer 335 can extend from the display area DA into the bezel areas BZA1 and BZA2. The passivation layer 335 can be disposed on the upper surface of the touch insulating layer 315 made of an organic insulating material in the bezel areas BZA1 and BZA2. The passivation layer 335 can be disposed on the surface of the touch insulating layer 315 exposed through the trench 315t. The passivation layer 335 may not cover a portion of the upper surface of the touch insulating layer 315 so as to be exposed in the second area A2 of the bezel areas BZA1 and BZA2. The passivation layer 335 may cover the inclined surface 315i of the touch insulating layer 315 in the third area A3 of the bezel areas BZA1 and BZA2. The passivation layer 335 may be made of an inorganic insulating material to prevent moisture or foreign matter from penetrating into the touch insulating layer 315.

[0150] The passivation layer 335 may be a single layer made of silicon oxide (SiOx) film, silicon nitride (SiNx) film, or silicon oxynitride (SiOxNy) film or its multilayer film.

[0151] Lens 340 can be disposed on passivation layer 335 and in display area DA. Figure 9 and Figure 11 The portion of the display area DA shown can be the edge of the display area DA adjacent to the border areas BZA1 and BZA2. Therefore, the lens 340 provided in the edge of the display area DA can act as a dummy pattern or lens.

[0152] A lens protective layer 350 can be disposed on the lens 340. The lens protective layer 350 can be formed by applying a fluid insulating material to flatten the step caused by the lens 340 and the like disposed below it. When there is no structure controlling the flow of the fluid insulating material in the bezel regions BZA1 and BZA2, the fluid insulating material may diffuse into the outer areas of the display panel due to its fluidity. For example, the fluid insulating material may flow into the third region A3 adjacent to the side end of the substrate 205 in the bezel regions BZA1 and BZA2. As a result, the height of the portion of the lens protective layer 350 in the display area DA near the edge of the bezel regions BZA1 and BZA2 may be reduced. Therefore, the height uniformity of the lens protective layer 350 in the entire display area DA may deteriorate.

[0153] Therefore, a structure for controlling the flow of a fluid insulating material can be provided on the passivation layer 335 and in the frame regions BZA1 and BZA2. For example, the structure for controlling the flow of the fluid insulating material can be implemented as multiple second structures such as multiple lens dams 500. The multiple lens dams 500 may include a first lens dam 510, a second lens dam 520, and a third lens dam 530. For example, the first lens dam 510 may be provided in the second region A2 to overlap with one of the multiple encapsulation dams 400 in the vertical direction. For example, the first lens dam 510 may be configured to overlap with the first encapsulation dam 410, but is not limited thereto. The second lens dam 520 may be provided outside the first lens dam 510. The third lens dam 530 may be provided outside the second lens dam 520. Adjacent lens dams among lens dams 510, 520, and 530 may be arranged to be spaced apart from each other by a predetermined distance. For example, each of the lens dams 510, 520, and 530 may have a linear shape that extends continuously around the display region DA in a plan view. For example, each of the lens dams 510, 520, and 530 may extend to form a closed loop rather than an open loop in a plan view. In the example, the multiple lens dams 500 may have the same thickness. However, embodiments of this disclosure are not limited thereto.

[0154] Each of the plurality of lens dams 500 may be made of the same material as lens 340 and may be formed in the same process as that used to form lens 340 for forming display area DA, but is not limited thereto. Therefore, display devices according to some embodiments of this disclosure can reduce the number of process steps, thereby reducing the production energy required to manufacture the display device and thus reducing greenhouse gas light emissions.

[0155] Multiple lens dams 500 may be located in the frame regions BZA1 and BZA2. At least one of the multiple lens dams 500 may be disposed in a second region A2 of the frame regions BZA1 and BZA2, and encapsulation dams 410, 420 and 430 may be disposed in the second region A2, but are not limited thereto.

[0156] Reference Figure 10 The first lens dam 510 may be configured to overlap with the first encapsulation dam 410 disposed in the second region A2 in the vertical direction. The first lens dam 510 may include a first head 511 and a first post 513. The first post 513 of the first lens dam 510 may fill the groove 315t. The first head 511 of the first lens dam 510 may be integrally formed with the first post 513 and may be disposed on the top surface of the first post 513. The first head 511 may be on the upper surface of the touch insulating layer 315 and extend along the upper surface of the touch insulating layer 315.

[0157] In a cross-sectional view, the groove 315t may have the same shape as the first pillar 513 of the first lens dam 510. In a plan view, the groove 315t may have a linear shape that extends continuously around the display area DA. For example, in a plan view, the groove 315t may extend so as to form a closed loop without being disrupted.

[0158] For example, the first width 510w of the first head 511 of the first lens dam 510 can have a dimension in the range of 40 μm to 55 μm. In this respect, width can refer to the width in the direction from the lens to the side end of the substrate. However, embodiments of the present disclosure are not limited to the above values. The height of the first head 511 of the first lens dam 510 can be less than the first width 510w. The height of the first head 511 can be the vertical length between the upper surface of the touch insulating layer 315 and the upper surface of the first head 511. For example, the height of the first head 511 of the first lens dam 510 can be in the range of 10 μm to 15 μm. The width and height of each of the second lens dam 520 and the third lens dam 530 can be equal to the first width 510w and height of the first head 511 of the first lens dam 510. Therefore, the width of each of the lens dams 510, 520 and 530 can be greater than its height. In this case, increasing the contact area of ​​the polarizing layer 360, which contacts each of the lens dams 510, 520 and 530 (described later), can prevent the occurrence of peeling defects of the polarizing layer 360.

[0159] The first lens dam 510 can be the structure that first contacts the border areas BZA1 and BZA2 when the fluid insulating material diffused from the display area DA reaches them.

[0160] Therefore, preferably, the upper surface of the first head 511 of the first lens dam 510 is positioned at a higher vertical level than the upper surfaces of the second lens dam 520 and the third lens dam 530, in order to control the flow of the fluid insulating material. Thus, the height of the first lens dam 510 can be maximized, and the height of the third lens dam 530 can be minimized. The height of the second lens dam 520 can be less than the height of the first lens dam 510 and greater than the height of the third lens dam 530, but is not limited thereto.

[0161] For example, when the portion of the upper surface of the first head 511 of the first lens dam 510 corresponding to the maximum thickness and the portion of the upper surface of the first encapsulation dam 410 disposed below it corresponding to the maximum thickness overlap each other in the vertical direction, the upper surface of the first head 511 of the first lens dam 510 can be located at a higher vertical level than the vertical level of the upper surfaces of each of the second lens dam 520 and the third lens dam 530. The height of the first head 511 of the first lens dam 510 can be maintained at a size that allows control over the flow of flowable insulating material. As a result, the first head 511 of the first lens dam 510 can prevent flowable insulating material from overflowing the second lens dam 520 or the third lens dam 530. For example, the portion of the upper surface of the first head 511 of the first lens dam 510 corresponding to the maximum thickness can be its central portion, through which a first center line C1 of a first width 510w perpendicularly passes. Furthermore, the portion of the upper surface of the first encapsulation dam 410 corresponding to the maximum thickness can be its central portion, through which a second center line C2 of a second width 410w perpendicularly passes. Each of the first center line C1 and the second center line C2 can be a virtual line that passes vertically through each of the first lens dam 510 and the first encapsulation dam 410. The first center line C1 can coincide with a center line that passes vertically through the center of the first pillar portion 513 of the first lens dam 510 in the width direction. However, embodiments of this disclosure are not limited thereto.

[0162] The first center line C1 of the first width 510w of the first head 511 of the first lens dam 510 can coincide with the second center line C2 of the second width 410w of the first encapsulation dam 410. Therefore, the flow of the fluid insulating material can be controlled by the first lens dam 510, which overlaps with the first encapsulation dam 410 in the vertical direction and has an upper surface positioned at a vertical level higher than the upper surface of each of the second lens dam 520 and the third lens dam 530.

[0163] As described above, the passivation layer 335 may not cover a portion of the upper surface of the touch insulating layer 315, thus exposing it in the second region A2 of the border regions BZA1 and BZA2. In the process of forming the plurality of lens dams 510, 520, and 530, the passivation layer 335 can be partially removed in the second region A2, omitting the protective mask process. Therefore, the portions of the upper surface of the touch insulating layer 315 disposed between the first lens dam 510 and the second lens dam 520, and the portions of the upper surface of the touch insulating layer 315 disposed between the second lens dam 520 and the third lens dam 530, may be exposed without being covered by the passivation layer 335.

[0164] In the second region, the passivation layer 335 can be partially removed to expose a portion of the upper surface of the touch insulating layer 315 made of an organic insulating material. Moisture can penetrate into the organic insulating material in high temperature and high humidity environments. Therefore, the touch insulating layer 315 made of the organic insulating material can serve as a moisture penetration path through which moisture flows. The touch insulating layer 315 extends into the display area DA, allowing the metal lines in the display area DA to be exposed to moisture. When the metal lines (such as touch lines) in the display area DA are exposed to moisture, there is a possibility that the metal lines may undergo electrolytic corrosion or be corroded.

[0165] Therefore, in a display device according to an exemplary embodiment of this disclosure, the trench 315t can prevent the touch insulating layer 315 from acting as a moisture penetration path. For example, as Figure 9 and Figure 10 As shown, the trench 315t can be positioned between the second region A2 and the first region A1, which is relatively close to the display region DA. The trench 315t divides the touch insulating layer 315 into two isolated portions. Therefore, the trench 315t can interrupt the continuity of the touch insulating layer 315 and allows the touch insulating layer 315 to be broken or discontinuous. Thus, as... Figure 10 As indicated by the arrow, the first groove 315t can block the flow of moisture through the exposed portion disposed between the first lens dam 510 and the second lens dam 520 on the upper surface of the touch insulating layer 315, so as not to intrude into the display area DA.

[0166] Furthermore, the surface of the touch insulating layer 315 exposed through the trench 315t can be covered by a passivation layer 335 made of an inorganic insulating material. Therefore, the passivation layer 335 formed in the trench can prevent the flow of moisture. Additionally, the trench 315t can be filled with the pillar portion of the first lens dam 510. The first lens dam 510 can include an organic insulating material having a second density relatively higher than the first density of the touch insulating layer 315. Therefore, the first pillar portion of the first lens dam 510 filling the trench 315t can further prevent moisture from penetrating into the display area DA. Thus, a display device meeting high reliability requirements can be achieved by preventing moisture from penetrating from outside the display device from flowing into the display area DA. In the example, the trench 315t can have a pillar shape extending through the touch insulating layer 315 and extending vertically to align with the first center line C1 and the second center line C2.

[0167] If the first lens dam 510 is disposed in a third region A3 located outside the second region A2 in which the encapsulation dams 410, 420, and 430 are disposed, the fluid insulating material flows into the third region A3. Then, the uniformity between the thickness of the portion of the lens protective layer 350 in the central region of the display region DA and the thickness of the portion of the lens protective layer 350 in the edge portions near the border regions BZA1 and BZA2 of the display region DA may deteriorate. Then, since the thickness of the lens protective layer 350 is not sufficiently ensured in the edge regions of the display region, there is a problem that the portion of the lens 340 in the edge regions of the display region is not protected by the lens protective layer 350. Furthermore, if the lens dams 510, 520, and 530 are disposed in the third region A3, the fluid insulating material may overflow. Therefore, preferably, at least one of the plurality of lens dams 500 is disposed in the second region A2 in which the encapsulation dams 410, 420, and 430 are disposed.

[0168] The second lens dam 520 can be located outside the first lens dam 510.

[0169] The third lens dam 530 may be disposed outside the second lens dam 520. Preferably, at least one of the lens dams 510, 520, and 530 is disposed in the second region A2 in which the encapsulation dams 410, 420, and 430 are disposed. For example, the first lens dam 510 may be disposed in the second region A2. The third lens dam 530 may include a first patterned portion 530a and a second patterned portion 530b. The first patterned portion 530a may have the same shape as the first lens dam 510 or the second lens dam 520. For example, the first patterned portion 530a may have the same shape as the first head 511 of the first lens dam 510 or the second lens dam 520. For example, the first patterned portion 530a may have a trapezoidal shape in cross-sectional view. However, embodiments of the present disclosure are not limited thereto.

[0170] The second pattern portion 530b of the third lens dam 530 can be embodied as an extended pattern extending outward from one side surface of the first pattern portion 530a. The second pattern portion 530b can extend toward the edge (or side end) of the substrate 205. For example, the second pattern portion 530b can extend along and on the inclined surface 315i of the touch insulating layer 315. The touch electrode 325 can extend from the display area DA to the edge (or side end) of the substrate 205.

[0171] The second pattern portion 530b can cover the touch electrode (or metal wire) located on the edge region (or end region) of the substrate 205 to prevent damage to the touch electrode from external impacts, moisture penetration, etc. This can prevent touch operation failure due to damage to the touch electrode, thereby improving product reliability. The first pattern portion 530a and the second pattern portion 530b can be integrally formed with each other. The second pattern portion 530b can be formed in a halftone manner.

[0172] A polarizing layer 360 can be disposed on the lens protective layer 350. The polarizing layer 360 can span the first region A1, second region A2, and third region A3 of the display area DA and the bezel regions BZA1 and BZA2. The lens protective layer 350 may not be disposed outside the first region A1 of the bezel regions BZA1 and BZA2. Furthermore, the upper surface of the first pattern portion 530a and the upper surface of the second pattern portion 530b disposed in the third region A3 can be disposed at different vertical levels. For example, the upper surface of the second pattern portion 530b disposed in the third region A3 may be located at a vertical level lower than the vertical level of the upper surface of the first pattern portion 530a, but is not limited to this. Therefore, the upper surface of the display area DA and the upper surfaces of the first region A1 to the third region A3 of the bezel regions BZA1 and BZA2 can be disposed at different vertical levels.

[0173] Multiple lens dams 500 can be disposed between the first region A1 and the third region A3. For example, multiple lens dams 500 can be disposed in the second region A2. The polarizing layer 360 can extend continuously across the first region A1 to the third region A3 while contacting the multiple lens dams 500 disposed in the second region A2. The tilt of the polarizing layer 360 can gradually decrease from the first region A1 toward the third region A3. The polarizing layer 360 can be attached in close contact to the second patterned portion 530b of the third lens dam 530 disposed at the edge of the third region A3, so it can be attached without peeling. Therefore, defects such as peeling of the polarizing layer 360 due to steps can be prevented.

[0174] The trenches that block moisture from penetrating into the display area DA can have various shapes. These will be described below with reference to the accompanying drawings.

[0175] Figures 12 to 14 These are diagrams illustrating display devices according to some other embodiments of the present disclosure. Besides the lens dam, Figures 12 to 14 Including with Figures 9 to 11 The components are the same. Therefore, redundant descriptions will be omitted or briefly stated, and the differences between them will be described. The same reference numerals may denote the same elements.

[0176] Reference Figure 12A plurality of trenches 315ta, 315tb, and 315tc may be formed in the touch insulating layer 315. Therefore, in a display device according to an exemplary embodiment of the present disclosure, the plurality of trenches 315ta, 315tb, and 315tc can prevent the touch insulating layer 315 from acting as a moisture penetration path. Each of the plurality of trenches 315ta, 315tb, and 315tc may extend vertically through the touch insulating layer 315 toward the substrate 205 and may expose a portion of the upper surface of the second touch buffer layer 305. The trenches 315ta, 315tb, and 315tc may be arranged to be spaced apart from each other by a predetermined distance. The trenches 315ta, 315tb, and 315tc may be spaced apart from each other in a direction toward the third region A3 of the border regions BZA1 and BZA2. At least one of the trenches 315ta, 315tb, and 315tc may be configured to overlap with at least one of the plurality of encapsulation dams 400 in the vertical direction. For example, the first trench 315ta among the plurality of trenches 315ta, 315tb and 315tc can be configured to overlap with the first encapsulation dam 410 among the plurality of encapsulation dams 400 in the vertical direction.

[0177] The second trench 315tb among the plurality of trenches 315ta, 315tb, and 315tc can be configured to overlap in the vertical direction with the region between the first pattern 265b1 and the second pattern 265b2 of the second encapsulation dam 420. However, embodiments of this disclosure are not limited thereto. The third trench 315tc among the plurality of trenches 315t can be configured to overlap in the vertical direction with the third encapsulation dam 430 among the plurality of encapsulation dams 400.

[0178] Each of trenches 315ta, 315tb, and 315tc may have a linear shape surrounding the outer periphery of the display area DA. For example, in a plan view, each of trenches 315ta, 315tb, and 315tc may have a linear shape that extends continuously around the display area DA. For example, in a plan view, each of trenches 315ta, 315tb, and 315tc may extend to form a closed loop rather than being open. A passivation layer 335 may be disposed on the surface of the touch insulating layer 315 exposed by each of trenches 315ta, 315tb, and 315tc.

[0179] A lens dam can be disposed in a groove. For example, a first groove 315ta can be filled with a first pillar 513 of a first lens dam 510, and a first head 511 of the first lens dam 510 can be disposed on the top surface of the first pillar 513. For example, in a cross-sectional view, the first groove 315ta can have the same shape as the first pillar 513 of the first lens dam 510. A second groove 315tb can be filled with a second pillar 523 of a second lens dam 520, and a second head 521 of the second lens dam 520 can be disposed on the top surface of the second pillar 523. For example, in a cross-sectional view, the second groove 315tb can have the same shape as the second pillar 523 of the second lens dam 520. A third groove 315tc can be filled with a third pillar 533 of a third lens dam 530, and a third head 531 of the third lens dam 530 can be disposed on the top surface of the third pillar 533. For example, in a cross-sectional view, the third groove 315tc may have the same shape as the third pillar portion 533 of the third lens dam 530. The third lens dam 530 may include a second patterned portion 530b extending outward from one side surface of the third head 531. The second patterned portion 530b may extend toward the edge (or side end) of the substrate 205. The vertical level of the upper surface of the second patterned portion 530b may be lower than the vertical level of the upper surface of the third head 531.

[0180] The upper surface of the first head 511 of the first lens dam 510 can be located at a higher vertical level than the upper surface of the second head 521 of the second lens dam 520 and the third head 531 of the third lens dam 530, to prevent the lens protection layer 350 from overflowing into the outer area of ​​the display panel. For this purpose, the first center line C1 of the first width 510w of the first head 511 of the first lens dam 510 can coincide with the second center line C2 of the second width 410w of the first encapsulation dam 410 located below it.

[0181] In the bezel areas BZA1 and BZA2, multiple trenches 315ta, 315tb, and 315tc can be formed in the touch insulating layer 315 and arranged in a direction toward the side of the substrate 205 away from the display area DA. Therefore, the moisture path penetrating into the display area DA is blocked in multiple ways, thereby preventing the metal lines from undergoing electrolytic corrosion or being corroded. This improves product reliability.

[0182] Reference Figure 13At least one trench 315ta may be defined in the touch insulating layer 315. The trench 315ta may extend vertically through the touch insulating layer 315 to expose a portion of the upper surface of the second touch buffer layer 305. The trench 315ta may be configured to overlap with the first encapsulation dam 410 of a plurality of encapsulation dams 400 in a vertical direction. The trench 315ta may have a closed-loop line shape that extends continuously along the outer periphery of the display area DA. The trench 315ta may include a first trench pattern 315t1 and a second trench pattern 315t2, which are arranged to be spaced apart from each other in a direction from the lens to the side end of the substrate. In an example, the entire combination of the first trench pattern 315t1 and the second trench pattern 315t2 of the trench 315ta may be contained in the area overlapping with the first encapsulation dam 410. The passivation layer 335 may be disposed on the surface of the touch insulating layer 315 exposed by each of the first trench pattern 315t1 and the second trench pattern 315t2 through the trench 315ta.

[0183] Multiple lens dams 510, 520, and 530 may be disposed on the touch insulating layer 315. A first lens dam 510 may include first pillars 517a and 517b and a first head 511. The first pillars 517a and 517b may include a (1-1) pillar 517a and a (1-2) pillar 517b that respectively fill the first groove pattern 315t1 and the second groove pattern 315t2 of the groove 315ta. The first pillars 517a and 517b and the first head 511 may be integrally formed with each other. In an example, the (1-1) pillar 517a and the (1-2) pillar 517b may be disposed on two opposite side edges of the bottom surface of the first head 511. The first head 511 may extend to the upper surface of the touch insulating layer 315. The first center line C1 of the first width 510w of the first head 511 of the first lens dam 510 can coincide with the second center line C2 of the second width 410w of the first encapsulation dam 410 located below it.

[0184] The second lens dam 520 and the third lens dam 530 can be disposed on the upper surface of the touch insulating layer 315.

[0185] In a display device according to another exemplary embodiment of the present disclosure, a trench 315ta comprising a plurality of trench patterns 315t1 and 315t2 arranged in a direction from the lens to the side end of the substrate can be defined in the touch insulating layer 315, thereby preventing moisture from penetrating into the display area DA in various ways. For example, the moisture path into the display area DA is blocked in various ways by the plurality of trench patterns 315t1 and 315t2, thereby preventing the metal lines from undergoing electrolytic corrosion or being corroded. Therefore, the occurrence of touch operation failures of the display device can be suppressed, thereby improving the reliability of the product. Furthermore, the trench 315ta comprising the plurality of trench patterns 315t1 and 315t2 can be defined only in one of the plurality of lens dams 510, 520 and 530. For example, the trench 315ta can be defined only in the first lens dam 510 of the plurality of lens dams 510, 520 and 530, thereby simplifying the manufacturing process. However, embodiments of the present disclosure are not limited thereto.

[0186] In another example, a groove 315ta comprising multiple groove patterns 315t1 and 315t2 can be defined in each of multiple lens dams 510, 520, and 530. For example, as Figure 14 As shown, the structure of the groove 315ta, including the first groove pattern 315t1 and the second groove pattern 315t2, can be applied not only to the first lens dam 510, but also to each of the second lens dam 520 and the third lens dam 530. For example, the second lens dam 520 may include second pillars 527a and 527b filling the groove 315tb and a second head 521. The second pillars 527a and 527b may include a (2-1) pillar 527a and a (2-2) pillar 527b respectively filling the first groove pattern 315t1 and the second groove pattern 315t2 of the groove 315tb. The second pillars 527a and 527b and the second head 521 may be integrally formed with each other. In the example, the (2-1) pillar 527a and the (2-2) pillar 527b may be respectively disposed on two opposite side edges of the bottom surface of the second head 521.

[0187] The third lens dam 530 may include third pillars 537a and 537b filling the groove 315tc and a third head 531. The third pillars 537a and 537b may include a (3-1) pillar 537t1 and a (3-2) pillar 537t2 respectively filling the first groove pattern 315t1 and the second groove pattern 315t2 of the groove 315tc. The third pillars 537a and 537b and the third head 531 may be integrally formed with each other. In the example, the (3-1) pillar 537a and the (3-2) pillar 537b may be respectively disposed on two opposite side edges of the bottom surface of the third head 531.

[0188] The first center line C1 of the first width 510w of the first head 511 of the first lens dam 510 can coincide with the second center line C2 of the second width 410w of the first encapsulation dam 410 located below it.

[0189] In a display device according to another exemplary embodiment of the present disclosure, a plurality of trenches 315ta to 315tc defined in the touch insulating layer 315 in the bezel regions BZA1 and BZA2 can be arranged in a direction toward the side end of the substrate 205 away from the display area DA, such that each of the plurality of trenches 315ta to 315tc includes a double trench arranged in the direction toward the side end of the substrate 205. Therefore, the moisture path for moisture to penetrate into the display area DA is blocked in various ways, thereby preventing the metal lines from undergoing electrolytic corrosion or being corroded. Therefore, the occurrence of touch operation failures in the display device can be suppressed, thereby improving product reliability.

[0190] Figure 15 and Figure 16 These are figures illustrating display devices according to some further embodiments of the present disclosure. Figure 15 It is along Figure 2 The cross-sectional view taken from line III-III'. Figure 16 yes Figure 15 A magnified view of region VI. Besides the lens dam. Figure 15 and Figure 16 Including with Figures 9 to 11 The components are the same. Therefore, redundant descriptions will be omitted or briefly stated, and the differences between them will be described. The same reference numerals may denote the same elements.

[0191] Reference Figure 15 and Figure 16 Multiple touch electrodes 325 may be disposed on a touch insulating layer 315 covering the underlying structure. At least one trench 315t for dividing the touch insulating layer 315 into spaced-apart portions may be defined in the touch insulating layer 315. The touch electrodes 325 may be disposed in the display area DA. A passivation layer 335 may be disposed on the touch electrodes 325. The passivation layer 335 may extend from the display area DA into a third region A3 of the bezel areas BZA1 and BZA2 to cover the inclined surface 315i of the touch insulating layer 315. The passivation layer 335 may comprise an inorganic insulating material.

[0192] Multiple lens dams 500 may be disposed on the passivation layer 335. The multiple lens dams 500 may include a first lens dam 510, a second lens dam 520, and a third lens dam 530. Each of the multiple lens dams 500 may be made of the same material as the lens 340 of the display area DA, and may be formed in the same process as the process used to form the lens 340 of the display area DA, but is not limited thereto.

[0193] The first lens dam 510 may include a first post 513 filling the groove 315t and a first head 511 disposed on the top surface of the first post 513. The first lens dam 510, the second lens dam 520, and the third lens dam 530 may be arranged to be spaced apart from each other in the frame regions BZA1 and BZA2. At least one of the plurality of lens dams 500 may be disposed in a second region A2 of the frame regions BZA1 and BZA2, in which encapsulation dams 410, 420, and 430 are disposed. For example, the first lens dam 510 may be configured to overlap with the first encapsulation dam 410 disposed in the second region A2 in the vertical direction. For example, as... Figure 10 As shown, the first center line C1 of the first width WD1 of the first lens dam 510 can coincide with the second center line C2 of the second width 410w of the first encapsulation dam 410 located below it.

[0194] Lens dams 510, 520, and 530 can have different heights H1, H2, and H3, respectively. (Refer to...) Figure 16 The first lens dam 510 may have a first height H1, the second lens dam 520 may have a second height H2, and the third lens dam 530 may have a third height H3.

[0195] The first lens dam 510 can be the structure that first contacts the flowable insulating material diffusing from the display area DA upon reaching the bezel areas BZA1 and BZA2. Therefore, it is preferable that the upper surface of the first head 511 of the first lens dam 510 is positioned at a higher vertical level than the vertical level of the upper surfaces of each of the second lens dam 520 and the third lens dam 530, in order to control the flow of the flowable insulating material. For example, the first height H1 of the first lens dam 510 can be the largest. The height of each of the second lens dam 520 and the third lens dam 530 can be less than the first height H1 of the first lens dam 510. Therefore, the first height H1 of the first lens dam 510 can be the largest, and the third height H3 of the third lens dam 530 can be the smallest. The second height H2 of the second lens dam 520 can be less than the first height H1 and greater than the third height H3, but is not limited thereto. As a result, the first head 511 of the first lens dam 510 can first prevent the flowable insulating material from overflowing the second lens dam 520 or the third lens dam 530.

[0196] In the example, the third lens dam 530 can be configured not to overlap with the third encapsulation dam 430 disposed below it and in the second region A2 in the vertical direction. For example, in a plan view, the third lens dam 530 can be disposed outside the third encapsulation dam 430, or disposed at a position corresponding to or overlapping with the position between the second pattern 265b2 of the second encapsulation dam 420 and the third encapsulation dam 430.

[0197] In another example, the third lens dam 530 can be configured to overlap with the third encapsulation dam 430 disposed below it and in the second region A2 in the vertical direction. In this case, the second lens dam 520 can be positioned at a location corresponding to or overlapping with the space S between the first pattern 265b1 and the second pattern 265b2 of the second encapsulation dam 420. When the third lens dam 530 overlaps with the third encapsulation dam 430 having a multilayer structure in the vertical direction, the third height H3 of the third lens dam 530 can be relatively greater than the second height H2 of the second lens dam 520. For example, the first height H1 of the first lens dam 510 can be the largest, and the second height H2 of the second lens dam 520 can be the smallest. Then, when the polarizing layer 360 is attached thereto, the physical pressure applied to the third lens dam 530, which has a relatively larger height than the second lens dam 520, can increase. When the physical pressure increases continuously, the third lens dam 530 may be damaged. When the third lens dam 530 is damaged, the second lens dam 520 can be used to supplement the third lens dam 530, thereby maintaining the polarization layer 360 attached to it. This can prevent the occurrence of peeling defects of the polarization layer 360 in the product.

[0198] Figure 17 This is a diagram illustrating a display device according to yet another exemplary embodiment of the present disclosure. Since, in addition to the lens dam, Figure 17 Including with Figure 15 The components in the figures are the same, therefore redundant descriptions will be omitted or briefly stated, and the differences between them will be described. The same reference numerals may denote the same elements.

[0199] Reference Figure 17 Multiple lens dams 500 may be disposed on the passivation layer 335. The multiple lens dams 500 may include a first lens dam 510, a second lens dam 520, and a third lens dam 530 overlapping the trench 315t. Each of the multiple lens dams 500 may be made of the same material as the lens 340 of the display area DA, and may be formed in the same process as that used to form the lens 340 of the display area DA, but is not limited thereto.

[0200] At least one of the plurality of lens dams 500 can be disposed in a second region A2 of the frame regions BZA1 and BZA2, wherein encapsulation dams 410, 420 and 430 are disposed. For example, the first lens dam 510 can be configured to overlap with the lower first encapsulation dam 410 in the vertical direction. For example, as Figure 10 As shown, the first center line C1 of the first width 510w of the first head 511 of the first lens dam 510 can coincide with the second center line C2 of the second width 410w of the first encapsulation dam 410 located below it.

[0201] Lens dams 510, 520, and 530 can be configured to have different heights. For example, the height of the first head 511 of the first lens dam 510 can be the largest. The height of each of the second lens dam 520 and the third lens dam 530 can be smaller than the height of the first head 511 of the first lens dam 510. For example, the height of the third lens dam 530 can be the smallest. The height of the second lens dam 520 can be smaller than the height of the first head 511 of the first lens dam 510 and larger than the height of the third lens dam 530, but is not limited thereto.

[0202] According to another exemplary embodiment of this disclosure, the height of each of the lens dams 510, 520, and 530 may be greater than its width in the direction from the lens to the side end of the substrate on its bottom surface. The first lens dam 510, the second lens dam 520, and the third lens dam 530 may be arranged in a stepped manner, with the vertical horizontality of their upper surfaces decreasing sequentially as they are arranged in the direction toward the side end of the substrate 205. The second lens dam 520 may be disposed between the first lens dam 510 and the third lens dam 530.

[0203] The polarizing layer 360 can continuously extend across the first region A1 to the third region A3 and be attached to the first region A1 to the third region A3. The polarizing layer 360 can contact the lens dams 510, 520 and 530 arranged in a stepped manner. Therefore, as the polarizing layer 360 extends towards the third region A3, the vertical level of the upper surface of the polarizing layer 360 can gradually decrease. Therefore, the polarizing layer 360 can be tightly attached to the second patterned portion 530b of the third lens dam 530 provided in the edge of the third region A3, and can be attached without peeling off.
