[0042] It will be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, the "first" element discussed below may also be named as the "second" element without departing from the disclosed teachings.

[0043] As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0044] It will also be understood that when used in this specification, the term "comprise" and / or variations thereof indicate the presence of stated features, integers, steps, operations, elements and / or components, but do not exclude the presence and / or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0045] For ease of description, spatially relative terms such as "under", "below", "below", "below", "above", "on", etc. may be used herein to describe the relationship of one element or feature to another (other) element or feature as shown in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, the elements described as "under" or "beneath" or "below" other elements or features will then be oriented as "above" the other elements or features. Therefore, the exemplary terms "under" and "below" can cover both above and below orientations.

[0046] It will be understood that when a component such as a film, region, layer, etc. is referred to as being "on," "connected to," "bound to," or "adjacent to" another component, it can be directly on, directly connected to, directly bound to, or directly adjacent to the other component, or there can be intervening components. It will also be understood that when a component is referred to as being "between" two components, it can be the only component between the two components, or there can also be one or more intervening components. It will also be understood that when a component is referred to as "overlaying" another component, it can be the only component that overlays the other component, or one or more intervening components can also overlay the other component. Other words used to describe relationships between components should be interpreted in a similar manner.

[0047] It should be understood that descriptions of features or aspects within each embodiment should typically be considered as available for other similar features or aspects in other embodiments, unless the context clearly dictates otherwise.

[0048] Here, when two or more elements (elements) or values ​​are described as being substantially the same or approximately equal to each other, it will be understood that elements (elements) or values ​​are the same as each other, elements (elements) or values ​​are equal to each other within a measurement error, or if measurably unequal, then as those of ordinary skill in the art will understand that in value, close enough to be functionally equal to each other. For example, the term "about (approximately)" as used herein includes stated values, and means within the acceptable deviation range of a specific value determined by those of ordinary skill in the art taking into account the measurement discussed and the error (e.g., the limitation of the measurement system) associated with a specific amount. For example, "about (approximately)" may mean within one or more standard deviations as understood by those of ordinary skill in the art. In addition, it will be understood that, although a parameter may be described as having "about (approximately)" certain value here, according to an embodiment, as will be understood by those of ordinary skill in the art, a parameter may be exactly the certain value or approximate the certain value within a measurement error. Other uses of these terms and similar terms used to describe the relationship between components should be interpreted in a similar manner.

[0049] Embodiments of the present disclosure generally relate to a display device including a touch sensor. Hereinafter, a display device including a touch sensor according to an embodiment of the disclosure will be described with reference to the accompanying drawings.

[0050] Figure 1 is a view showing a display device according to a disclosed embodiment. Figure 2 is a schematic cross-sectional view showing a stacked structure of a display device according to a disclosed embodiment.

[0051] Reference Figure 1 and Figure 2 The display device DD is configured to provide (or emit) light. The display device DD may include a panel PNL and a driving circuit DV driving the panel PNL. The display device DD may further include an external part OUP.

[0052] The panel PNL may include a display portion DP that displays an image and a sensor portion TSP that can sense a user input (eg, a touch input). The display portion DP may be, for example, a display panel. The sensor portion TSP may be, for example, a sensing panel (eg, a touch sensing panel).

[0053] The panel PNL may include a sub-pixel SPX and a sensing electrode SP. In some embodiments, the sub-pixel SPX may display an image by using a display frame period as a unit. The sensing electrode SP may sense a user's input (e.g., a touch input) by using a sensing frame period as a unit. The sensing frame period and the display frame period may be independent of or different from each other. The sensing frame period and the display frame period may be synchronized or asynchronous with each other.

[0054] The sensor part TSP may acquire information about a user's touch input. The sensing electrode SP may include a first sensing electrode SP1 that provides a first sensing signal and a second sensing electrode SP2 that provides a second sensing signal. According to an embodiment (e.g., a mutual capacitance type), the first sensing electrode SP1 may be a transmitter (Tx) pattern electrode, and the second sensing electrode SP2 may be a receiver (Rx) pattern electrode. Information about a touch input (or a touch event) may mean, for example, a location of a touch to be provided by a user.

[0055] However, the disclosure is not limited thereto.For example, according to an embodiment (eg, a self-capacitance type), the sensing electrode SP may be configured with one type of sensing electrode without distinguishing the first sensing electrode SP1 and the second sensing electrode SP2 from each other.

[0056] The driving circuit DV may include a display driver (display integrated circuit, D-IC) DDV driving the display part DP and a sensor driver (touch integrated circuit, T-IC) SDV driving the sensor part TSP.

[0058] The display base layer DBSL (or the display device DD) may include a display area DA in which an image is displayed and a non-display area NDA (e.g., an area other than the display area DA) in which no image is displayed. In some embodiments, the display area DA may be disposed in a central area of ​​the display portion DP, and the non-display area NDA may be disposed adjacent to the periphery of the display area DA. However, the disclosure is not limited thereto.

The sub-pixel SPX can be selected by the scan signal with a conduction level supplied from the scan line SL to be supplied with the data signal from the data line DL and emit light with brightness corresponding to the data signal. Therefore, an image corresponding to the data signal is displayed in the display area DA. However, in the disclosure, the structure, driving method, etc. of the sub-pixel SPX are not particularly limited.

[0061] Various types of lines and / or built-in circuits connected to the subpixels SPX of the display area DA may be disposed in the non-display area NDA. For example, a plurality of lines supplying various power sources and various control signals to the display area DA may be disposed in the non-display area NDA.

[0062] The display portion DP can output visual information (e.g., images). In some embodiments, the type / kind of the display portion DP is not particularly limited. For example, the display portion DP can be implemented as a self-luminous display panel such as an organic light-emitting display panel. However, when the display portion DP is implemented as a self-luminous display panel, each pixel is not necessarily limited to the case where the pixel only includes an organic light-emitting element. For example, the light-emitting element of each pixel can be configured as an organic light-emitting diode, an inorganic light-emitting diode, a quantum dot / well light-emitting diode, etc. In some embodiments, the display portion DP can be implemented as a non-luminous display panel such as a liquid crystal display panel. When the display portion DP is implemented as a non-luminous display panel, the display device DD can additionally include a light source such as a backlight unit.

In some embodiments, the sensing area SA may be disposed to overlap with at least one area of ​​the display area DA. For example, the sensing area SA may be set to an area corresponding to the display area DA (e.g., an area overlapping the display area DA), and the non-sensing area NSA may be set to an area corresponding to the non-display area NDA (e.g., an area overlapping the non-display area NDA). When a touch input, etc. is provided in the display area DA, the touch input may be detected by the sensor portion TSP.

[0066] The sensor base layer SBSL may include at least one insulating layer (eg, a first insulating layer INS1 (see Figure 4 )). For example, a first insulating layer INS1 forming the sensor base layer SBSL may be disposed on the display part DP to form a base for allowing the sensing electrode SP to be formed thereon.

[0073] The driving circuit DV may include a display driver DDV driving the display part DP and a sensor driver SDV driving the sensor part TSP.

[0094] The first conductive pattern layer CP1 may be disposed on the first insulating layer INS1. The second conductive pattern layer CP2 may be disposed on the second insulating layer INS2. The first conductive pattern layer CP1 and the second conductive pattern layer CP2 may be separated from each other with the second insulating layer INS2 interposed therebetween.

[0095] The first conductive pattern layer CP1 and the second conductive pattern layer CP2 may include a single layer or multiple layers of metal layers. The first conductive pattern layer CP1 and the second conductive pattern layer CP2 may include at least one of various metal materials including, for example, gold (Au), silver (Ag), aluminum (Al), molybdenum (Mo), chromium (Cr), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), platinum (Pt), etc. or their alloys. In some embodiments, the first conductive pattern layer CP1 and the second conductive pattern layer CP2 may include, for example, silver nanowires (AgNW), indium tin oxide (ITO), indium zinc oxide (IZO), indium gallium zinc oxide (IGZO), antimony zinc oxide (AZO), indium tin zinc oxide (ITZO), zinc oxide (ZnO), tin oxide (SnO 2 ), at least one of various transparent conductive materials such as carbon nanotubes, graphene, etc.

[0096] The second insulating layer INS2 may be disposed on the first conductive pattern layer CP1. The second insulating layer INS2 may be interposed between the first conductive pattern layer CP1 and the second conductive pattern layer CP2. The protective layer PVX may be disposed on the second conductive pattern layer CP2.

[0097] The first insulating layer INS1 may include at least one of an inorganic material and an organic material. The second insulating layer INS2 may include at least one of an inorganic material and an organic material. In some embodiments, the protective layer PVX may include an organic material. The inorganic material may include, for example, silicon nitride (SiN x ), silicon oxide (SiO x ), silicon oxynitride (SiO x N y ) and aluminum oxide (AlO x ). The organic material may include, for example, at least one of acrylic resin, epoxy resin, phenolic resin, polyamide resin, and polyimide resin. However, the disclosure is not limited thereto.

[0098] The sensing electrode SP may include a cell C and a bridge BRD. The cell C may have a relatively wide area, and the bridge BRD may have a relatively narrow area. The cells C adjacent to each other may be electrically connected to each other through the bridge BRD. The cell C may include a first cell C1 and a second cell C2. The bridge BRD may include a first bridge BRD1 and a second bridge BRD2.

[0099] In some embodiments, the first unit C1 and the second unit C2 may be formed by the second conductive pattern layer CP2. The first bridge BRD1 may be formed by the second conductive pattern layer CP2. A portion of the second bridge BRD2 may be formed by the first conductive pattern layer CP1, and another portion of the second bridge BRD2 may be formed by the second conductive pattern layer CP2.

[0100] However, the disclosure is not necessarily limited thereto. For example, the first unit C1 and the second unit C2 may be formed by the first conductive pattern layer CP1. The first bridge BRD1 may be formed by the first conductive pattern layer CP1. A portion of the second bridge BRD2 may be formed by the second conductive pattern layer CP2, and another portion of the second bridge BRD2 may be formed by the first conductive pattern layer CP1.

[0101] In some embodiments, the sensing electrode SP may have a mesh structure MESH. The cell C and the bridge BRD may have a mesh structure MESH. For example, the second conductive pattern layer CP2 forming the sensing electrode SP may be patterned according to the mesh structure MESH. The sensing electrode SP has the mesh structure MESH, and thus, the capacitance that the sensing electrode SP may form with other electrodes disposed under the cell C may be reduced. The mesh structure MESH may be formed by the disconnection area OPA (see FIG. Figure 8 ) and the separation disconnection area SOPA (see Figure 8 ) to limit.

[0102] The first sensing electrode SP1 may have a structure in which a first cell C1 having a relatively wide area and a first bridge BRD1 having a relatively narrow area are connected to each other. For example, the first cell C1 may include a 1-1th cell C1-1 and a 1-2th cell C1-2, and the first bridge BRD1 may electrically connect the 1-1th cell C1-1 and the 1-2th cell C1-2 to each other.

[0103] The second sensing electrode SP2 may have a structure in which the second cell C2 having a relatively wide area and the second bridge BRD2 having a relatively narrow area are connected to each other. For example, the second cell C2 may include a 2-1st cell C2-1 and a 2-2nd cell C2-2, and the second bridge BRD2 may electrically connect the 2-1st cell C2-1 and the 2-2nd cell C2-2 to each other.

[0104] In some embodiments, the second bridge BRD2 may be electrically connected to the 2-1st cell C2-1 through a contact CNT, and electrically connected to the 2-2nd cell C2-2 through another contact CNT. Therefore, the second bridge BRD2 disposed in a layer different from the layer in which the second cell C2 is disposed may electrically connect the 2-1st cell C2-1 and the 2-2nd cell C2-2 through the contact CNT. In some embodiments, the contact CNT may penetrate the second insulating layer INS2.

[0105] The first cell C1 and the second cell C2 may have a rhombus shape as a whole ( Figure 5 ). However, the shapes of the first cell C1 and the second cell C2 are not particularly limited thereto. For example, the first cell C1 and the second cell C2 may have a quadrilateral shape as a whole ( Figure 6 ).

[0106] The separation line SEL may be defined between the sensing electrodes SP electrically separated from each other. For example, the first sensing electrode SP1 and the second sensing electrode SP2 may be adjacent to each other and the separation line SEL is disposed between the first sensing electrode SP1 and the second sensing electrode SP2. The separation line SEL may be a virtual line disposed in a region between the first sensing electrode SP1 and the second sensing electrode SP2. For example, the separation line SEL may be disposed (e.g., formed or defined) between the 1-1th cell C1-1 and the 1-2th cell C1-2. The separation line SEL may be disposed (e.g., formed or defined) between the first bridge BRD1 and the 1-2th cell C1-2.

[0107] Will refer to Figures 8 to 11 A cover layer COV and a disconnection area OPA according to a disclosed embodiment are described.

[0108] Figure 8 and Fig. 9 is a schematic cross-sectional view showing a sensor portion including a cover layer according to an embodiment disclosed. For ease of description, Figure 8 and Fig. 9 The second conductive pattern layer CP2 and the cover layer COV disposed on the second insulating layer INS2 are shown. Fig.10 is a schematic plan view showing an arrangement structure of a disconnection region and a separated disconnection region according to a disclosed embodiment. Fig.11 is a schematic plan view showing an arrangement structure of a first cover layer and a second cover layer with respect to a disconnection region and a separation disconnection region according to a disclosed embodiment.

[0109] Reference Figure 8 and Fig. 9 , the sensor part TSP may further include a cover layer COV.

[0110] The cover layer COV may be selectively disposed at a portion in the sensing area SA. The cover layer COV may be disposed on the second insulating layer INS2. The cover layer COV may cover a portion of the second conductive pattern layer CP2.

[0111] The covering layer COV may be covered by the protective layer PVX. The top surface of the covering layer COV may be entirely covered by the protective layer PVX. For example, the top surface of the covering layer COV may be in contact with the protective layer PVX. A portion of the covering layer COV may be in contact with a portion of the second conductive pattern layer CP2.

[0112] In some embodiments, the cover layer COV may have a low reflectivity. For example, in an embodiment, the cover layer COV does not substantially reflect external light. Even when external light is applied to the display device DD, the risk that visibility will decrease due to external light can be reduced.

[0113] In some embodiments, the cover layer COV may include a material having a low reflectivity. For example, the cover layer COV may include a material that substantially does not reflect external light or reflects a minimal or substantially reduced amount of applied external light.

[0114] In some embodiments (see Figure 8 ), the cover layer COV may include an organic material as a material having low reflectivity. In some embodiments, when the cover layer COV includes an organic material, the cover layer COV may have a structure protruding along the third direction DR3 on the second insulating layer INS2. For example, the cover layer COV may include at least one of a black pigment and a black dye as a black matrix material. For example, the cover layer COV may include a carbon black pigment, etc. However, the disclosure is not limited thereto.

[0115] For example, in some embodiments (see Fig. 9 ), the cover layer COV may include an inorganic material as a material with low reflectivity. In some embodiments, the cover layer COV may include a multilayer or a single layer including an inorganic material. However, the disclosure is not limited thereto.

[0116] The cover layer COV may include first and second cover layers COV1 and COV2 that may be spaced apart from each other in a plane direction in which the first insulating layer INS1 is disposed (eg, a direction in which a plane defined by the first and second directions DR1 and DR2 extends).

[0117] The first cover layer COV1 may be disposed on the second insulating layer INS2 in the disconnection area OPA. In a plan view, the first cover layer COV1 may overlap the disconnection area OPA. The first cover layer COV1 may entirely cover the disconnection area OPA.

[0118] The first cover layer COV1 may be disposed on the second insulating layer INS2 in the separation disconnection area SOPA. In a plan view, the first cover layer COV1 may overlap the separation disconnection area SOPA. The first cover layer COV1 may entirely cover the separation disconnection area SOPA.

[0119] In an embodiment, the second cover layer COV2 does not overlap the disconnection area OPA in a plan view. For example, the second cover layer COV2 may overlap the disconnection area OPA along the first direction DR1. The second cover layer COV2 may overlap the disconnection area OPA along the second direction DR2.

[0120] In some embodiments, the first cover layer COV1 and the second cover layer COV2 may overlap each other along the first direction DR1 and overlap each other along the second direction DR2. Therefore, the risk that visibility will be reduced due to external light reflection can be reduced. The arrangement structure of the first cover layer COV1 and the second cover layer COV2 will be described below.

[0121] The disconnection area OPA may be a first opening area. The separation disconnection area SOPA may be a second opening area.

[0122] In an embodiment, the disconnection area OPA and the separated disconnection area SOPA do not overlap the second conductive pattern layer CP2 in a plan view. In an embodiment, the second conductive pattern layer CP2 is not disposed in the disconnection area OPA and the separated disconnection area SOPA.

[0123] Each of the disconnection area OPA and the separation disconnection area SOPA may be an area formed by removing a portion of the second conductive pattern layer CP2. Each of the disconnection area OPA and the separation disconnection area SOPA may be an area formed by disconnecting a portion of the second conductive pattern layer CP2.

[0124] For example, the first portion P1 of the second conductive pattern layer CP2 may have a first edge portion EDG1. The side of the first portion P1 may be exposed at the first edge portion EDG1. The second portion P2 of the second conductive pattern layer CP2 may have a second edge portion EDG2. The side of the second portion P2 may be exposed at the second edge portion EDG2.

[0125] Each of the disconnection area OPA and the separation disconnection area SOPA may be a region between the first edge portion EDG1 and the second edge portion EDG2 .

[0126] For example, the first portion P1 may be a portion of the first sensing electrode SP1, the second portion P2 may be a portion of the first sensing electrode SP1, and the disconnection area OPA may be defined inside the first sensing electrode SP1 (for example, inside the first cell C1). The first portion P1 may be a portion of the second sensing electrode SP2, the second portion P2 may be a portion of the second sensing electrode SP2, and the disconnection area OPA may be defined inside the second sensing electrode SP2 (for example, inside the second cell C2).

[0127] For example, the first portion P1 may be a portion of the first sensing electrode SP1, the second portion P2 may be a portion of the second sensing electrode SP2, and the separation disconnection area SOPA may be defined in an area in which the first sensing electrode SP1 and the second sensing electrode SP2 are adjacent to each other. In a plan view, the separation disconnection area SOPA may correspond to (e.g., overlap) the separation line SEL.

[0128] In some embodiments, the disconnection areas OPA may be arranged in a matrix structure along the first direction DR1 and the second direction DR2. For example, the disconnection areas OPA may be arranged sequentially along the first direction DR1 (eg, the column direction). The disconnection areas OPA may be arranged sequentially along the second direction DR2 (eg, the row direction).

[0129] The disconnection area OPA forming a matrix structure may be formed in the first sensing electrode SP1 (eg, the first cell C1 ). The disconnection area OPA forming a matrix structure may be formed in the second sensing electrode SP2 (eg, the second cell C2 ).

[0130] In some embodiments, the separation disconnection area SOPA may be disposed between disconnection areas OPA. For example, the separation disconnection area SOPA may be disposed between disconnection areas OPA adjacent to each other along the second direction DR2. In some embodiments, the separation disconnection area SOPA may be disposed between disconnection areas OPA adjacent to each other along the first direction DR1.

[0131] The separation disconnection area SOPA may be sequentially arranged along a direction (eg, a first direction DR1). The separation disconnection area SOPA may be formed between the first sensing electrode SP1 (eg, the first cell C1) and the second sensing electrode SP2 (eg, the second cell C2). Therefore, the separation disconnection area SOPA may form a separation line SEL.

[0132] In some embodiments, the separation disconnection area SOPA together with the disconnection area OPA may be arranged in a matrix structure. For example, the separation disconnection area SOPA and the disconnection area OPA may be arranged sequentially along the first direction DR1. The separation disconnection area SOPA and the disconnection area OPA may be arranged sequentially along the second direction DR2.

[0133] As described above, the first cover layer COV1 may be disposed in the disconnection area OPA and the separation disconnection area SOPA. Therefore, the first cover layer COV1 may be patterned according to a reference (eg, a matrix structure).

[0134] In addition, the second cover layer COV2 may be disposed in a region in which the disconnection area OPA and the separation disconnection area SOPA are not formed. The first cover layer COV1 and the second cover layer COV2 may be patterned according to a reference (eg, a matrix structure).

[0135] Therefore, the arrangement structure in which the cover layers COV (e.g., the first cover layer COV1 and the second cover layer COV2) are patterned can be uniformly defined throughout the sensing area SA, thereby preventing or reducing the risk of reflection of external light caused by the disconnection area OPA and the separation disconnection area SOPA.

[0136] The disconnection area OPA and the separation disconnection area SOPA may be formed adjacent to each other at a point where a portion extending in the first direction DR1 and another portion extending in the second direction DR2 intersect each other in the second conductive pattern layer CP2 patterned at the peripheral portion of the area in which the sub-pixel SPX (or the sub-pixel area SPXA) is formed. This will be described in detail in conjunction with the arrangement structure of the sub-pixel SPX.

[0137] Refer to the following Fig.12 A cross-sectional structure of a display device DD according to a disclosed embodiment is described. Fig.12 is a schematic cross-sectional view showing a display device according to a disclosed embodiment.

[0138] Reference Fig.12 , the light emitting layer EL may include a first light emitting layer EL1 included in the first sub-pixel SPX1, a second light emitting layer EL2 included in the second sub-pixel SPX2, and a third light emitting layer EL3 included in the third sub-pixel SPX3. The first light emitting layer EL1 may emit light of a first color (e.g., red) and form a first sub-pixel region SPXA1. The second light emitting layer EL2 may emit light of a second color (e.g., green) and form a second sub-pixel region SPXA2. The third light emitting layer EL3 may emit light of a third color (e.g., blue) and form a third sub-pixel region SPXA3.

[0139] The first conductive pattern layer CP1 and the second conductive pattern layer CP2 in the sensor part TSP may be disposed in different layers to form a structure of the sensing electrode SP.

[0140] The outer part OUP may be disposed on the sensor part TSP. The outer part OUP may allow at least a portion of the light provided from the light emitting layer EL to be transmitted therethrough. In some embodiments, the outer part OUP may include a light blocking layer LBL and a reflection control layer RCL. However, the structure of the outer part OUP is not limited thereto. For ease of description, the display device DD will be described based on an embodiment in which the outer part OUP includes a light blocking layer LBL and a reflection control layer RCL.

[0141] In a plan view, the light blocking layer LBL may overlap the first conductive pattern layer CP1 and the second conductive pattern layer CP2. The light blocking layer LBL may include a light blocking material, but the disclosure is not necessarily limited thereto.

[0142] The reflection control layer RCL can selectively absorb light having a wavelength range, thereby controlling the reflectivity and color sensing of the display device DD. In some embodiments, the reflection control layer RCL may include, for example, at least one of an oxazine compound, a cyanine compound, a tetrazoloporphine compound, and a squarylium compound, but the disclosure is not limited thereto.

[0143] In some embodiments, the sizes (or areas) of the sub-pixel regions SPXA may be different from each other. The areas of the first sub-pixel region SPXA1, the second sub-pixel region SPXA2, and the third sub-pixel region SPXA3 may be different from each other. For example, the area of ​​the third sub-pixel region SPXA3 may be larger than the area of ​​the second sub-pixel region SPXA2. The area of ​​the second sub-pixel region SPXA2 may be larger than the area of ​​the first sub-pixel region SPXA1. However, the disclosure is not necessarily limited to this. In some embodiments, the area of ​​the second sub-pixel region SPXA2 and the area of ​​the first sub-pixel region SPXA1 may be the same. Hereinafter, for ease of description, the display device DD will be described based on an embodiment in which the area of ​​the second sub-pixel region SPXA2 is larger than the area of ​​the first sub-pixel region SPXA1.

[0144] In some embodiments, some sub-pixel areas SPXA may be manufactured to have different areas, and thus, emission efficiency deviation of the sub-pixel SPX for each color may be compensated.

[0145] In some embodiments, the outer portion OUP does not include any color filters.

[0146] Referring to the comparative example, when a color filter is included in the display device DD, the overall thickness of the display device DD increases. In addition, when a color filter including a red color filter, a green color filter, and a blue color filter is included in the display device DD, the red color filter, the green color filter, and the blue color filter are stacked to form a light blocking structure for dividing the sub-pixel area SPXA. The formed light blocking structure may be difficult to manufacture to have a narrow width. Therefore, the width of the sub-pixel area SPXA is reduced, or the distance between the sub-pixel areas SPXA is extended. However, according to the disclosed embodiment, since the color filter is not included, the above-mentioned risks can be prevented, and a display device DD with excellent visibility can be provided.

[0147] In some embodiments, the display part DP may further include a color conversion layer including quantum dots that may convert the color of applied light. The color conversion layer may be disposed above the light emitting element LD, and the position of the color conversion layer is not particularly limited.

[0148] In the following, reference will be made to Figures 13 to 23 The structures of the first conductive pattern layer CP1, the second conductive pattern layer CP2, the cover layer COV, and the sub-pixel SPX of the display device DD according to the disclosed embodiment are described. For ease of explanation, further description of previously described components and technical aspects may be omitted.

[0149] Will refer to Figures 13 to 19 A display device DD according to a disclosed embodiment is described.

[0150] Figures 13 to 19 is a schematic diagram showing a display device according to a disclosed embodiment.

[0151] Figures 13 to 17 and Fig.19 is a schematic plan view showing a display device DD according to a disclosed embodiment. Fig.18 is a schematic cross-sectional view showing a display device DD according to a disclosed embodiment.

[0152] Figures 13 to 17 is a schematic plan view showing the sub-pixel area SPXA and the second conductive pattern layer CP2. Figures 13 to 17 The sub-pixels SPX1 , SPX2 , and SPX3 (or the light emitting layers EL1 , EL2 , and EL3 ) forming the sub-pixel regions SPXA1 , SPXA2 , and SPXA3 are illustrated, and the second conductive pattern layer CP2 formed at the periphery of the sub-pixel region SPXA is illustrated. Fig.13 The sensing electrodes SP1 and SP2 are shown to be adjacent to each other with respect to the separation line SEL. Fig.16 and Fig.17 A cover layer COV disposed in a region adjacent to the sub-pixel region SPXA is further illustrated. Fig.18 It is along Fig.14 A schematic cross-sectional view taken along line CC' shown in FIG. Fig.19 is a schematic enlarged view showing a region in which the first cover layer COV1 is provided. Fig.19 yes Fig.15 Schematic enlargement of the area EA1 shown in FIG.

[0153] The sub-pixels SPX according to the disclosed embodiments may be arranged according to a structure. For example, the sub-pixels SPX may be arranged according to an S-strip structure. However, the disclosure is not necessarily limited thereto. The arrangement structure of the sub-pixels SPX may be implemented differently.

[0154] In the following description, a positional relationship between the sub-pixels SPX1 , SPX2 , and SPX3 may correspond to a positional relationship between the sub-pixel regions SPXA1 , SPXA2 , and SPXA3 and / or the light emitting layers EL1 , EL2 , and EL3 .

[0155] The first subpixel SPX1 and the second subpixel SPX2 may form a first pixel column COL1. The first subpixel SPX1 and the second subpixel SPX2 may be sequentially disposed along the first direction DR1. The first subpixel SPX1 and the second subpixel SPX2 may be alternately disposed along the first direction DR1. No third subpixel SPX3 is disposed in the first pixel column COL1, but the first subpixel SPX1 and the second subpixel SPX2 may be disposed in the first pixel column COL1.

[0156] The third subpixel SPX3 may form the second pixel column COL2. The third subpixel SPX3 may be sequentially disposed along the first direction DR1. No first subpixel SPX1 and second subpixel SPX2 are disposed in the second pixel column COL2, but the third subpixel SPX3 may be disposed in the second pixel column COL2.

[0157] The first pixel column COL1 and the second pixel column COL2 may be adjacent to each other along the second direction DR2. For example, the first subpixel SPX1 may be adjacent to the third subpixel SPX3 along the second direction DR2. The second subpixel SPX2 may be adjacent to the third subpixel SPX3 along the second direction DR2.

[0158] The first pixel column COL1 and the second pixel column COL2 may be alternately arranged along the second direction DR2. For example, the second pixel column COL2 may be disposed between two first pixel columns COL1. The first pixel column COL1 may be disposed between two second pixel columns COL2.

[0159] The first and second subpixels SPX1 and SPX2 adjacent to each other along the first direction DR1 may form a pixel PXL (or a pixel unit) with a third subpixel SPX3 adjacent to the first and second subpixels SPX1 and SPX2 along the second direction DR2 .

[0160] In some embodiments, in the display device DD, at least some of the sensing electrodes SP (e.g., cells C) may be formed by the second conductive pattern layer CP2. In some embodiments, at least a portion of the second conductive pattern layer CP2 may surround at least one of the sub-pixel areas SPXA. Thus, the second conductive pattern layer CP2 may form a mesh structure MESH.

[0161] In some embodiments, the first sensing electrode SP1 and the second sensing electrode SP2 may be disposed adjacent to the sub-pixel region SPXA. For example, the first sensing electrode SP1 and the second sensing electrode SP2 may be separated from each other relative to the separation line SEL. For example, the first cell C1 and the second cell C2 may be separated from each other and the separation line SEL may be disposed between the first cell C1 and the second cell C2.

[0162] In some embodiments, since at least a portion of the second conductive pattern layer CP2 can be cut (e.g., disconnected), a separation disconnection area SOPA for defining (e.g., forming) a separation line SEL can be formed. Since the second conductive pattern layers CP2 are electrically separated from each other and the separation line SEL is placed between the second conductive pattern layers CP2, the first sensing electrode SP1 and the second sensing electrode SP2 to which different sensing signals can be supplied can be defined.

[0163] The location of the separation disconnection area SOPA is not limited to Fig.13 The location shown in .

[0164] The position where the separation disconnection area SOPA is formed may intersect with a portion of the second conductive pattern layer CP2 (eg, the intersection CA) (see FIG. 1 ). Fig.19 ) to form the corresponding position of the mesh structure MESH. This will be referred to below Fig.19 Combined with the location description of the disconnection region OPA.

[0165] The second conductive pattern layer CP2 may be disposed at the periphery of the sub-pixel SPX (or the sub-pixel region SPXA). The second conductive pattern layer CP2 may surround at least a portion of the sub-pixel region SPXA. Since the second conductive pattern layer CP2 is disposed at the peripheral portion of the sub-pixel SPX, a reduction in luminous efficiency may be prevented, and a reduction in external visibility may be minimized or reduced.

[0166] As described above, when forming the separation disconnection area SOPA, the separation line SEL defined to define the sensing electrodes SP1 and SP2 may be provided. In addition, the disconnection area OPA forming a pattern structure with the separation disconnection area SOPA is provided, and thus, the reduction of external visibility may be further prevented or reduced.

[0167] According to an embodiment, the position where the disconnection area OPA is formed may be defined relative to each pixel PXL. Since the pixel PXL is repeatedly disposed (e.g., repeatedly patterned) relative to the disconnection area OPA defined in the pixel PXL, the disconnection area OPA may be formed (e.g., repeatedly formed according to a predetermined reference) in the sensing area SA relative to the pattern structure.

[0168] For example, the first subpixel SPX1, the second subpixel SPX2, and the third subpixel SPX3 may form a pixel PXL, and the disconnection area OPA may be provided at each of one side and the other side of the defined pixel PXL. In an embodiment, the disconnection area OPA is not formed in an area inside the defined pixel PXL.

[0169] In some embodiments, the disconnection area OPA may be disposed on a first virtual line VL1 between the first sub-pixel area SPXA1 and the third sub-pixel area SPXA3. The first virtual line VL1 may be a line on which a portion of the second conductive pattern layer CP2 disposed adjacent to the upper sides of the first sub-pixel area SPXA1 and the third sub-pixel area SPXA3 extends. The first virtual line VL1 may extend in the second direction DR2. Therefore, the disconnection area OPA may be disposed at one side of the pixel PXL and between the first sub-pixel area SPXA1 and the third sub-pixel area SPXA3 with respect to the second direction DR2.

[0170] In some embodiments, the disconnection area OPA may be disposed on a second virtual line VL2 between the second sub-pixel area SPXA2 and the third sub-pixel area SPXA3. The second virtual line VL2 may be a line on which a portion of the second conductive pattern layer CP2 disposed adjacent to the lower sides of the second sub-pixel area SPXA2 and the third sub-pixel area SPXA3 extends. The second virtual line VL2 may extend in the second direction DR2. Therefore, the disconnection area OPA may be disposed at one side of the pixel PXL and between the second sub-pixel area SPXA2 and the third sub-pixel area SPXA3 relative to the second direction DR2.

[0171] In some embodiments, the disconnection area OPA is not disposed on the middle virtual line VL_N. The middle virtual line VL_N may pass through the inner area of ​​the pixel PXL. The middle virtual line VL_N may pass through at least one of the sub-pixel areas SPXA1, SPXA2, and SPXA3. For example, the middle virtual line VL_N may pass through the third sub-pixel area SPXA3. In some embodiments, the middle virtual line VL_N may be a line on which a portion (e.g., the middle extension layer ML) of the second conductive pattern layer CP2 formed between the first sub-pixel area SPXA1 and the second sub-pixel area SPXA2 extends.

[0172] Each of the first virtual line VL1 and the second virtual line VL2 may be formed at an edge portion of the pixel PXL. The first virtual line VL1 and the second virtual line VL2 may be parallel to each other. In some embodiments, the first virtual line VL1 and the second virtual line VL2 may be parallel to the middle virtual line VL_N. The middle virtual line VL_N may be disposed between the first virtual line VL1 and the second virtual line VL2.

[0173] When the pixels PXL are repeatedly arranged, the disconnection areas OPA formed at positions relative to the virtual lines VL1 and VL2 may be arranged in a matrix structure. For example, the disconnection area OPA may be arranged between the first pixel column COL1 and the second pixel column COL2. The disconnection area OPA may be arranged between different pixels PXL adjacent to each other along the first direction DR1.

[0174] According to an embodiment, the first cover layer COV1 may cover the disconnection area OPA, and the second cover layer COV2 may be disposed in an area where the disconnection area OPA is not formed according to a predetermined reference. Therefore, the second cover layer COV2 may overlap the first cover layer COV1 in the first direction DR1 and the second direction DR2.

[0175] For example, the first cover layer COV1 may be disposed on the first virtual line VL1 and the second virtual line VL2. The second cover layer COV2 may be disposed on the first virtual line VL1 and the second virtual line VL2. In an embodiment, the first cover layer COV1 and the second cover layer COV2 are not disposed on the middle virtual line VL_N. Therefore, the first cover layer COV1 and the second cover layer COV2 may form a matrix structure.

[0176] According to embodiments, the cover layer COV may have various shapes in a plan view. For example, in some embodiments, the cover layer COV may have a circular shape (or an elliptical shape) in a plan view (see Fig.15 ). For example, in some embodiments, the cover layer COV may have a polygonal shape (eg, a quadrilateral shape) in a plan view (see Fig.16 ). However, the disclosure is not limited thereto.

[0177] According to an embodiment, the disconnection area OPA may be defined at the intersection CA where the second conductive pattern layers CP2 intersect each other to form a mesh structure MESH. Therefore, the first cover layer COV1 may be defined at the intersection CA where the second conductive pattern layers CP2 intersect each other.

[0178] For example, the second conductive pattern layer CP2 forming the sensing electrode SP (e.g., the cell C) may include a first extension portion EXP1 extending in a first extension direction (e.g., the first direction DR1) and a second extension portion EXP2 extending in a second extension direction (e.g., the second direction DR2) different from the first extension direction. The first extension portion EXP1 and the second extension portion EXP2 may intersect each other at an intersection CA. The intersection CA may be a node portion where the first extension portion EXP1 and the second extension portion EXP2 overlap each other in a plan view.

[0179] In some embodiments, in the sensing area SA (eg, in an area in which the cells C are formed), other portions of the second conductive pattern layer CP2 may extend from the intersection CA in four or more directions.

[0180] For example, the first extension portion EXP1 may include a 1-1 extension portion EXP1-1 extending from the intersection portion CA along a 1-1 extension direction and a 1-2 extension portion EXP1-2 extending from the intersection portion CA along a 1-2 extension direction. The second extension portion EXP2 may include a 2-1 extension portion EXP2-1 extending from the intersection portion CA along a 2-1 extension direction and a 2-2 extension portion EXP2-2 extending from the intersection portion CA along a 2-2 extension direction.

[0181] However, the disclosure is not limited thereto, and the directions along which the portions of the second conductive pattern layer CP2 extend may be defined with respect to five or more directions instead of four directions.

[0182] The 1-1 extension direction may be an upper direction relative to the intersection CA. The 1-2 extension direction may be a lower direction relative to the intersection CA. The 2-1 extension direction may be a right direction relative to the intersection CA. The 2-2 extension direction may be a left direction relative to the intersection CA.

[0183] In some embodiments, the 1-1st extension direction and the 1-2nd extension direction may be parallel to the first direction DR1. The 2-1st extension direction and the 2-2nd extension direction may be parallel to the second direction DR2. However, the disclosure is not limited thereto.

[0184] In some embodiments, the disconnection area OPA may be formed in one or more of the extensions EXP1-1, EXP1-2, EXP2-1, and EXP2-2. Fig.19 An embodiment in which the disconnection area OPA is formed at the 2-2nd extension portion EXP2-2 is shown. However, the disclosure is not limited thereto, and the disconnection area OPA may be formed at one or more portions among the extension portions EXP1-1, EXP1-2, EXP2-1, and EXP2-2.

[0185] In some embodiments, the cover layer COV may be disposed to overlap the intersection CA. The cover layer COV may be patterned so that a central portion of the cover layer COV substantially corresponds to a central portion of the intersection CA. The cover layer COV (e.g., a first cover layer COV1) may cover at least a portion of each of the extension portions EXP1-1, EXP1-2, EXP2-1, and EXP2-2, and entirely cover the disconnection area OPA.

[0186] According to an embodiment, the cover layer COV may be patterned to overlap with the intersection CA and with a portion of the second conductive pattern layer CP2 extending in four or more directions, and thus, the risk that visibility will be reduced due to the formation of the disconnection area OPA may be prevented or reduced. For example, the range in which the cover layer COV covers the area in which the second conductive pattern layer CP2 is not provided may be minimized or reduced, and thus, the extent to which the area in which light is emitted is covered may be minimized or reduced.

[0187] According to an embodiment, the second conductive pattern layer CP2 may include a protrusion PRU protruding from at least a portion of the extensions EXP1-1, EXP1-2, EXP2-1, and EXP2-2. For ease of description, an embodiment in which the protrusion PRU protrudes from the body part BOD when the 1-1th extension part EXP1-1 forms the body part BOD will be mainly described.

[0188] The protrusion portion PRU may protrude in the direction in which the first virtual line VL1 and the second virtual line VL2 extend. For example, the protrusion portion PRU may be integrally formed with the body portion BOD and extend in the second direction DR2.

[0189] The protrusion PRU may be adjacent to the third sub-pixel area SPXA3. The protrusion PRU may be disposed between the third sub-pixel area SPXA3 and a portion of another second conductive pattern layer CP2 (e.g., the 2-1 extension portion EXP2-1). The separation area SPA may be formed between the protrusion PRU and the portion of another second conductive pattern layer CP2 (e.g., the 2-1 extension portion EXP2-1). In some embodiments, the separation area SPA may be directly adjacent to the cover layer COV. At least a portion of the cover layer COV may be disposed in the separation area SPA. The protrusion PRU may overlap with the third sub-pixel area SPXA3 along the first direction DR1. In some embodiments, the protrusion PRU may overlap with the second sub-pixel area SPXA2 along the second direction DR2.

[0190] According to an embodiment, when the protrusion PRU is formed, the widths of the extensions EXP1-1, EXP1-2, EXP2-1, and EXP2-2 extending in four or more directions relative to the intersection CA may be substantially uniformly set. The portion of the second conductive pattern layer CP2 formed at the upper side of the pixel PXL and the portion of the second conductive pattern layer CP2 formed at the lower side of the pixel PXL may have widths corresponding to each other and extend in the same direction. Therefore, visibility may be further improved.

[0191] According to embodiments, when the protrusion PRU is formed, the spacing distance between the sub-pixel area SPXA and the second conductive pattern layer CP2 may be substantially uniformly defined. The second conductive pattern layer CP2 according to the disclosed embodiments may be spaced apart from each of the sub-pixel areas SPXA at ​​a substantially uniform distance.

[0192] For example, in a plan view, the first sub-pixel region SPXA1 may be separated from the second conductive pattern layer CP2 by a first distance D1. In a plan view, the second sub-pixel region SPXA2 may be separated from the second conductive pattern layer CP2 by a second distance D2. In a plan view, the third sub-pixel region SPXA3 may be separated from the second conductive pattern layer CP2 by a third distance D3. Each of the first distance D1, the second distance D2, and the third distance D3 may be defined relative to a portion of the second conductive pattern layer CP2 that is closest to each of the sub-pixel regions SPXA. In some embodiments, the first distance D1, the second distance D2, and the third distance D3 may be substantially the same, and thus, visibility may be further improved.

[0193] Will refer to Figure 20 to Figure 22 A display device DD according to a disclosed embodiment is described. For convenience of explanation, further description of previously described components and technical aspects may be omitted.

[0194] Figure 20 to Figure 22is a schematic diagram showing a display device according to a disclosed embodiment.

[0195] Fig. 20 and Fig.21 is a schematic plan view showing a display device DD according to a disclosed embodiment. Fig. 22 is a schematic cross-sectional view showing a display device DD according to a disclosed embodiment.

[0196] Fig. 20 and Fig.21 may be a schematic plan view illustrating the sub-pixel area SPXA and the second conductive pattern layer CP2. Fig. 22 It is along Fig.21 A schematic cross-sectional view taken along line DD′ shown in FIG.

[0197] Reference Figure 20 to Figure 22 The display device DD according to the embodiment is different from the display device DD according to the above embodiment in that the second conductive pattern layer CP2 has a relatively wide width between third sub-pixel areas SPXA3 adjacent to each other along the first direction DR1, and the second bridge BRD2 is disposed under the second conductive pattern layer CP2.

[0198] In some embodiments, the second bridge BRD2 is a part of the second sensing electrode SP2 and may be formed of the first conductive pattern layer CP1. The second bridge BRD2 may be electrically connected to the 2-1st cell C2-1 through the contact portion CNT. The second bridge BRD2 may be electrically connected to the 2-2nd cell C2-2 through the contact portion CNT.

[0199] In some embodiments, in a plan view, the second bridge BRD2 may overlap the separation disconnection area SOPA.In a plan view, the second bridge BRD2 may overlap the cover layer COV.

[0200] In some embodiments, the first bridge BRD1 is a portion of the first sensing electrode SP1 and may be formed of the second conductive pattern layer CP2. At least a portion of the first bridge BRD1 may be disposed between the second sub-pixel areas SPXA2.

[0201] The portion of the second cell C2 electrically connected to the second bridge BRD2 may extend in the second direction DR2 and have a first width W1 between the first sub-pixel region SPXA1 and the second sub-pixel region SPXA2 relative to the first direction DR1. The first bridge BRD1 may extend in the first direction DR1 and have a second width W2 between the second sub-pixel region SPXA2 relative to the second direction DR2. In some embodiments, the second width W2 may be wider than the first width W1.

[0202] In addition, if Fig.21As shown, the width of the second conductive pattern layer CP2 (first bridge BRD1) between the third sub-pixel regions SPXA3 relative to the first direction DR1 is greater than the first width W1. According to an embodiment, since the second conductive pattern layer CP2 has a wide width between some sub-pixel regions SPXA, the second bridge BRD2 is completely covered. Since the second conductive pattern layer CP2 having a wide width is directly covered by the cover layer COV, the risk that visibility will be reduced can be reduced.

[0203] Similar to the above-described embodiment, the position of the cover layer COV is defined with respect to the pixel PXL, and the cover layer COV is patterned according to a reference, so that visibility can be improved.

[0204] Will refer to Fig.23 A display device DD according to a disclosed embodiment is described. For convenience of explanation, further description of previously described components and technical aspects may be omitted.

[0205] Fig.23 is a schematic diagram showing a display device according to a disclosed embodiment.

[0206] Fig.23 is a schematic plan view showing a display device DD according to a disclosed embodiment. Fig.23 is a schematic plan view showing the sub-pixel area SPXA and the second conductive pattern layer CP2.

[0207] Reference Fig.23 The display device DD according to the embodiment is different from the display device DD according to the above-described embodiment in that the second conductive pattern layer CP2 is not disposed between the third sub-pixel areas SPXA3.

[0208] For example, a portion of the second conductive pattern layer CP2 having a relatively wide width may be disposed between some of the third sub-pixel regions SPXA3, and the second bridge BRD2 may be disposed below the second conductive pattern layer CP2. In addition, since the second conductive pattern layer CP2 is not disposed between other third sub-pixel regions SPXA3, other third sub-pixel regions SPXA3 may be directly adjacent to each other.

[0209] Similar to the above-described embodiment, the position of the cover layer COV is defined with respect to the pixel PXL, and the cover layer COV is patterned according to a reference, so that visibility can be improved.

[0210] According to the disclosed embodiments, a display device including a touch sensor that can improve visibility is provided.

[0211] According to the disclosed embodiments, there is provided a display device including a touch sensor in which a cross-sectional structure of a panel is simplified so that processing properties can be improved.

[0212] While the present disclosure has been particularly shown and described with reference to embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the claims.
