[0047] Although terms such as "first," "second," etc. may be used to describe various components, these components are not limited to the above terms. The above terms are only used to distinguish one component from another.

[0048] In the following embodiments, expressions used in the singular encompass expressions in the plural unless clearly having a different meaning in the context.

[0049] It will be understood that the terms “comprising,” “having,” and “including” are intended to indicate the presence of features or elements described in the present specification, and are not intended to exclude the possibility that one or more other features or elements may be present or may be added.

[0051] For the convenience of explanation, the size of the components in the drawings may be exaggerated or reduced. For example, because the size and thickness of the components in the drawings are arbitrarily shown for the convenience of explanation, the present disclosure is not limited thereto.

[0052] In the description of a process, a manufacturing method, etc., the order of the process or method may be different from the order described. For example, two consecutively described processes may be performed simultaneously or substantially simultaneously, or may be performed in the reverse order of the described order.

For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other.

[0055] Figure 1 is a plan view schematically showing a display device 1 according to an embodiment.

[0056] refer to Figure 1, the display device 1 can be used not only for portable electronic devices such as mobile phones, smart phones, tablet personal computers, mobile communication terminals, electronic notepads, electronic books, portable multimedia players (PMPs), navigation devices, or ultra mobile computers (UMPCs), but also for display screens of various products such as televisions, laptop computers, monitors, billboards, or Internet of Things (IoT) products. In addition, the display device 1 according to the embodiment can be used in wearable devices such as smart watches, watch phones, glasses-type displays, or head-mounted displays (HMDs). In addition, the display device 1 according to the embodiment can be used as a central information display (CID) located on the dashboard, center panel, or instrument panel of a vehicle, an interior mirror display that replaces the side mirrors of the vehicle, or a display screen located on the back of the front seats.

[0057] The display device 1 may include a display area DA and a peripheral area PA located outside the display area DA. The display device 1 may provide an image using an array of pixels PX arranged in the display area DA. The pixels PX may include pixel circuits and light-emitting elements connected to the pixel circuits. The image may be provided by light emitted from the light-emitting elements of the pixels PX. Because the area providing the image is determined by the arrangement of the multiple light-emitting elements, the display area DA may be defined by the multiple light-emitting elements. The display area DA may also include various signal wiring and power wiring electrically connected to the pixel circuits.

[0058] The peripheral area PA not providing an image may completely or partially surround the display area DA. A driving circuit and various wirings for supplying an electrical signal or power to the display area DA may be located in the peripheral area PA.

[0059] In an embodiment, the display area DA of the display device 1 may have a circular shape or an elliptical shape when viewed in a direction perpendicular to one surface thereof. Figure 1 As shown in FIG, the display area DA of the display device 1 may have a circular shape in a plan view. The shape of the display area DA of the display device 1 is not limited to a circular shape or an elliptical shape, and may be various shapes such as a polygonal shape or an irregular shape other than a quadrilateral shape.

[0060] Figure 2 2 is a cross-sectional view schematically showing the display device 1 . Figure 2 1 is a cross-sectional view schematically showing the display area DA in the display device 1 .

[0061] refer to Figure 2 The display device 1 may include a display panel 10 and a touch sensing unit 20 disposed on the display panel 10. In an embodiment, the display device 1 may further include an optical function layer 30 disposed on the touch sensing unit 20.

[0062] The display panel 10 may include a substrate 100 , a display layer 200 disposed on the substrate 100 , and an encapsulation member 300 on the display layer 200 .

[0063] The substrate 100 may include glass or a polymer resin. Examples of polymer resins may include polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, and cellulose acetate propionate. The substrate 100 including the polymer resin may be flexible, rollable, or bendable. The substrate 100 may have a multilayer structure including a polymer resin and an inorganic layer (not shown).

[0064] The display layer 200 may be provided on the substrate 100. The display layer 200 may include a thin film transistor TFT, a display element electrically connected to the thin film transistor TFT, and an insulating layer IL. Although the display layer 200 includes an organic light emitting diode OLED as Figure 2 , but this is merely an example and the present disclosure is not limited thereto. For example, the display device 1 may include an organic light-emitting diode (OLED) including an organic emission layer, an inorganic light-emitting diode (ILD) including an inorganic emission layer, or a quantum dot light-emitting diode (QD) including a quantum dot emission layer as a display element. For ease of explanation, the following description will assume that the display device 1 includes an organic light-emitting diode (OLED).

[0065] The encapsulation member 300 may be provided on the display layer 200. The encapsulation member 300 may include at least one inorganic encapsulation layer and at least one organic encapsulation layer. In an embodiment, the encapsulation member 300 may include a first inorganic encapsulation layer 310 and a second inorganic encapsulation layer 330, and an organic encapsulation layer 320 between the first inorganic encapsulation layer 310 and the second inorganic encapsulation layer 330.

[0066] The touch sensing unit 20 can obtain coordinate information of an external input such as a touch event. The touch sensing unit 20 may include a plurality of touch electrodes and signal lines connected to the plurality of touch electrodes. The touch sensor included in the touch sensing unit 20 may detect an external input using, for example, a mutual capacitance method or a self-capacitance method.

[0067] Despite Figure 2The touch sensing unit 20 is provided as a separate element provided on the display panel 10, but the present disclosure is not limited thereto. In an embodiment, the touch sensing unit 20 may be formed separately from the display panel 10 and may be attached to the display panel 10 using an adhesive layer such as an optically clear adhesive (OCA). In an embodiment, the touch sensing unit 20 may be embedded in the display panel 10. For example, the touch sensing unit 20 may be formed directly on the packaging member 300 of the display panel 10, and an adhesive layer may not be interposed between the packaging member 300 and the touch sensing unit 20.

[0068] The optical function layer 30 may be formed on the touch sensing unit 20. The optical function layer 30 may include an anti-reflection layer. The anti-reflection layer may reduce reflectivity of light (external light) incident on the display device 1.

[0069] Figure 3 is a plan view schematically illustrating the touch sensing unit 20 included in the display device 1 . Figure 4 It is schematically shown Figure 3 An enlarged view of portion "E" of FIG.

[0070] refer to Figure 3 and Figure 4 , the touch sensing unit 20 may include a touch active area SA and a touch inactive area NSA located around the touch active area SA. The touch active area SA may overlap with the display area DA of the display device 1, and the touch inactive area NSA may overlap with the peripheral area PA of the display device 1. The touch active area SA may have a shape similar to or the same as the display area DA. In an embodiment, in a plan view, similar to the display area DA having a circular shape, the touch active area SA may have a circular shape. The shape of the touch active area SA is not limited thereto, and the touch active area SA may have various shapes such as a polygonal shape other than a quadrilateral shape, a circular shape, an elliptical shape, or an irregular shape.

[0071] The touch active area SA may be an area for sensing input applied from the outside. The input applied from the outside may be provided in various ways. For example, the input applied from the outside may include various types of external inputs, such as a user's finger touch, a stylus, light, heat, or pressure. In addition, the input applied from the outside may include input applied at a position close to the display device (e.g., hovering) and input contacting the display device (e.g., by the touch of a user's finger).

[0072] The touch sensing unit 20 may include drive electrode lines TEL and sensing electrode lines REL disposed in the touch active area SA. Each of the drive electrode lines TEL may extend in a first direction (e.g., the x-direction). The drive electrode lines TEL may be spaced apart from each other in a second direction (e.g., the y-direction) that intersects the first direction (e.g., the x-direction). Each of the sensing electrode lines REL may extend in the second direction (e.g., the y-direction). The sensing electrode lines REL may be spaced apart from each other in the first direction (e.g., the x-direction).

[0073] The first direction in which the driving electrode lines TEL extend (for example, the x direction) and the second direction in which the sensing electrode lines REL extend (for example, the y direction) may be different directions that intersect each other. For example, when the row direction is referred to as the first direction (for example, the x direction), the second direction (for example, the y direction) may be the column direction. For example, the driving electrode lines TEL may be arranged in the first row R1 to the nth row Rn, and the sensing electrode lines REL may be arranged in the first column C1 to the mth column Cm (each of n and m is a natural number greater than or equal to 3). For ease of explanation, the following description will be made assuming that the driving electrode lines TEL extend in the row direction and the sensing electrode lines REL extend in the column direction. The number of driving electrode lines TEL and the number of sensing electrode lines REL may be changed in various ways depending on the embodiment. For ease of explanation, as Figure 3 As shown in , the following description will be made assuming that each of n and m is 7 or greater.

[0074] In an embodiment, the driving electrode lines TEL may include at least two driving electrode lines TEL having different lengths. For example, the length of the driving electrode line TEL arranged in the p-th row Rp may be greater than the length of the driving electrode line TEL arranged in the q-th row Rq (p and q are different natural numbers equal to or greater than 1 and equal to or less than n).

[0075] In an embodiment, when the touch active area SA has Figure 3 , the length of the driving electrode line TEL located in the p-th row Rp is the largest, and the length of the driving electrode line TEL may decrease as the driving electrode line TEL moves away from the center, where the p-th row Rp is the center row among the first row R1 to the n-th row Rn. That is, the length of the driving electrode line TEL may decrease as the driving electrode line TEL approaches the touch invalid area NSA. For example, the length of the driving electrode line TEL set in the p-th row Rp may be greater than the length of the driving electrode line TEL set in the s-th row Rs, and the length of the driving electrode line TEL set in the s-th row Rs may be greater than the length of the driving electrode line TEL set in the t-th row Rt (p 、s and t are different natural numbers that are equal to or greater than 1 and equal to or less than n). In an embodiment, the s-th row Rs may be a row located between the first row R1 and the p-th row Rp, and the t-th row Rt may be a row located between the first row R1 and the s-th row Rs. Similarly, for example, the length of the driving electrode line TEL set in the p-th row Rp may be greater than the length of the driving electrode line TEL set in the q-th row Rq, and the length of the driving electrode line TEL set in the q-th row Rq may be greater than the length of the driving electrode line TEL set in the r-th row Rr (p, q, and r are different natural numbers that are equal to or greater than 1 and equal to or less than n). In an embodiment, the q-th row Rq may be a row located between the p-th row Rp and the n-th row Rn, and the r-th row Rr may be a row located between the q-th row Rq and the n-th row Rn.

[0076] In an embodiment, when the touch active area SA has Figure 3 When the circular shape is shown in FIG, the lengths of the driving electrode lines TEL in two rows spaced the same distance from the p-th row Rp as the center row may be substantially the same. For example, the s-th row Rs and the q-th row Rq may be spaced the same distance from the p-th row Rp, and the lengths of the driving electrode lines TEL in the s-th row Rs may be substantially the same as the lengths of the driving electrode lines TEL in the q-th row Rq. For example, the t-th row Rt and the r-th row Rr may be spaced the same distance from the p-th row Rp, and the lengths of the driving electrode lines TEL in the t-th row Rt may be substantially the same as the lengths of the driving electrode lines TEL in the r-th row Rr.

[0077] In an embodiment, the sensing electrode line REL may include at least two sensing electrode lines REL having different lengths. For example, the length of the sensing electrode line REL arranged in the a-th column Ca may be greater than the length of the sensing electrode line REL arranged in the b-th column Cb (a and b are different natural numbers equal to or greater than 1 and equal to or less than m).

[0078] In an embodiment, when the touch active area SA has Figure 3, the length of the sensing electrode line REL located in the a-th column Ca may be the largest, and the length of the sensing electrode line REL may decrease as the sensing electrode line REL moves away from the center, wherein the a-th column Ca is the center column among the first column C1 to the m-th column Cm. That is, the length of the sensing electrode line REL may decrease as the sensing electrode line REL approaches the touch invalid area NSA. For example, the length of the sensing electrode line REL located in the a-th column Ca may be greater than the length of the sensing electrode line REL located in the b-th column Cb, and the length of the sensing electrode line REL arranged in the b-th column Cb may be greater than the length of the sensing electrode line REL arranged in the c-th column Cc (a, b, and c are different natural numbers equal to or greater than 1 and equal to or less than m). In an embodiment, the c-th column Cc may be a column located between the a-th column Ca and the m-th column Cm, and the b-th column Cb may be a column located between the a-th column Ca and the c-th column Cc. Similarly, for example, the length of the sensing electrode line REL arranged in the a-th column Ca may be greater than the length of the sensing electrode line REL arranged in the d-th column Cd, and the length of the sensing electrode line REL arranged in the d-th column Cd may be greater than the length of the sensing electrode line REL arranged in the e-th column Ce (a, d, and e are different natural numbers equal to or greater than 1 and equal to or less than m). In an embodiment, the d-th column Cd may be a column located between the first column C1 and the a-th column Ca, and the e-th column Ce may be a column located between the first column C1 and the d-th column Cd.

[0079] In an embodiment, when the touch active area SA has Figure 3 , the lengths of the sensing electrode lines REL arranged in two columns spaced at the same distance from the a-th column Ca as the center column may be substantially the same. For example, the b-th column Cb and the d-th column Cd may be spaced at the same distance from the a-th column Ca, and the lengths of the sensing electrode lines REL arranged in the b-th column Cb may be substantially the same as the lengths of the sensing electrode lines REL arranged in the d-th column Cd. For example, the c-th column Cc and the e-th column Ce may be spaced at the same distance from the a-th column Ca, and the lengths of the sensing electrode lines REL arranged in the c-th column Cc may be substantially the same as the lengths of the sensing electrode lines REL arranged in the e-th column Ce.

[0080] The driving electrode line TEL may include a plurality of driving electrodes TE and a plurality of first connection patterns SP1. Figure 4As shown in . The driving electrodes TE included in each of the driving electrode lines TEL may be arranged in a first direction (e.g., the x-direction). The driving electrodes TE included in each driving electrode line TEL (i.e., the driving electrodes TE located in the same row) may be connected by a first connection pattern SP1 extending along the same row. That is, the first connection pattern SP1 may be provided between two driving electrodes TE adjacent to each other in the first direction (e.g., the x-direction).

[0081] The sensing electrode line REL may include a plurality of sensing electrodes RE and a plurality of second connection patterns SP2. Figure 4 As shown in . The sensing electrodes RE included in each of the sensing electrode lines REL can be arranged in the second direction (e.g., the y direction). The sensing electrodes RE included in each sensing electrode line REL (i.e., the sensing electrodes RE located in the same column) can be connected by a second connection pattern SP2 extending along the same column. That is, the second connection pattern SP2 can be provided between two sensing electrodes RE adjacent to each other in the second direction (e.g., the y direction).

[0082] The touch sensing unit 20 may include a plurality of touch sensors TS located in the touch active area SA. The touch sensors TS may be located at the intersections of the drive electrode lines TEL and the sensing electrode lines REL. Because the touch sensors TS are located at the intersections of the drive electrode lines TEL extending in the row direction and the sensing electrode lines REL extending in the column direction, the touch sensors TS may be arranged in a matrix of first to nth rows R1 to Rn and first to mth columns C1 to Cm. Each of the touch sensors TS may be located at the intersection of a first connection pattern SP1 and a second connection pattern SP2.

[0083] Each of the touch sensors TS may include a first connection pattern SP1, a second connection pattern SP2, and a touch electrode TCE. The touch electrode TCE may include a drive electrode TE and a sensing electrode RE. The touch electrodes TCE included in each of the touch sensors TS may include the drive electrodes TE located on the left and right sides of the first connection pattern SP1 and the sensing electrodes RE located on the upper and lower sides of the second connection pattern SP2. Each of the touch sensors TS may detect an external touch through the drive electrodes TE and the sensing electrodes RE, where each of the drive electrodes TE and the sensing electrodes RE is located adjacent to an area overlapping the first and second connection patterns SP1 and SP2.

[0084] The number of touch sensors TS arranged in at least two different rows may be different from each other. For example, the number of touch sensors TS arranged in the p-th row Rp may be greater than the number of touch sensors TS in the q-th row Rq.

[0085] In an embodiment, when the touch active area SA has Figure 3 , the number of touch sensors TS arranged in the p-th row Rp may be the largest, and the number of touch sensors TS arranged in a row may decrease as the row in which the touch sensors TS are located moves away from the p-th row Rp, where the p-th row R is the center row among the first to n-th rows Rn. That is, the number of touch sensors TS may decrease as the touch sensors TS get closer to the touch inactive area NSA. For example, the number of touch sensors TS arranged in the p-th row Rp may be greater than the number of touch sensors TS arranged in the s-th row Rs, and the number of touch sensors TS arranged in the s-th row Rs may be greater than the number of touch sensors TS arranged in the t-th row Rt (p, s, and t are different natural numbers equal to or greater than 1 and equal to or less than n). In an embodiment, the s-th row Rs may be a row located between the first row R1 and the p-th row Rp, and the t-th row Rt may be a row located between the first row R1 and the s-th row Rs. Similarly, for example, the number of touch sensors TS arranged in the p-th row Rp may be greater than the number of touch sensors TS arranged in the q-th row Rq, and the number of touch sensors TS arranged in the q-th row Rq may be greater than the number of touch sensors TS arranged in the r-th row Rr (p, q, and r are different natural numbers equal to or greater than 1 and equal to or less than n). In an embodiment, the q-th row Rq may be a row located between the p-th row Rp and the n-th row Rn, and the r-th row Rr may be a row located between the q-th row Rq and the n-th row Rn.

[0086] In an embodiment, when the touch active area SA has Figure 3 , the number of touch sensors TS arranged in two rows spaced the same distance from the p-th row Rp, which is the center row, may be the same. For example, the s-th row Rs and the q-th row Rq may be spaced the same distance from the p-th row Rp, and the number of touch sensors TS arranged in the s-th row Rs may be the same as the number of touch sensors TS arranged in the q-th row Rq. For example, the t-th row Rt and the r-th row Rr may be spaced the same distance from the p-th row Rp, and the number of touch sensors TS arranged in the t-th row Rt may be the same as the number of touch sensors TS arranged in the r-th row Rr.

[0087] The number of touch sensors TS located in at least two different columns may be different from each other. For example, the number of touch sensors TS arranged in the a-th column Ca may be greater than the number of touch sensors TS arranged in the b-th column Cb.

[0088] In an embodiment, when the touch active area SA has Figure 3, the number of touch sensors TS arranged in the a-th column Ca may be the largest, and the number of touch sensors TS arranged in a column may decrease as the column in which the touch sensors TS are arranged moves away from the a-th column Ca, where the a-th column Ca is the center column among the first column C1 to the m-th column Cm. That is, the number of touch sensors TS may decrease as the touch sensors TS get closer to the touch inactive area NSA. For example, the number of touch sensors TS arranged in the a-th column Ca may be greater than the number of touch sensors TS arranged in the b-th column Cb, and the number of touch sensors TS arranged in the b-th column Cb may be greater than the number of touch sensors TS arranged in the c-th column Cc (a, b, and c are different natural numbers equal to or greater than 1 and equal to or less than m). In an embodiment, the c-th column Cc may be a column located between the a-th column Ca and the m-th column Cm, and the b-th column Cb may be a column located between the a-th column Ca and the c-th column Cc. Similarly, the number of touch sensors TS arranged in the a-th column Ca may be greater than the number of touch sensors TS arranged in the d-th column Cd, and the number of touch sensors TS arranged in the d-th column Cd may be greater than the number of touch sensors TS arranged in the e-th column Ce (a, d, and e are different natural numbers equal to or greater than 1 and equal to or less than m). In an embodiment, the d-th column Cd may be a column located between the first column C1 and the a-th column Ca, and the e-th column Ce may be a column located between the first column C1 and the d-th column Cd.

[0089] In an embodiment, when the touch active area SA has Figure 3 , the number of touch sensors TS arranged in two columns spaced the same distance from the a-th column Ca, which is the center column, can be the same. For example, the b-th column Cb and the d-th column Cd can be spaced the same distance from the a-th column Ca, and the number of touch sensors TS arranged in the b-th column Cb can be the same as the number of touch sensors TS arranged in the d-th column Cd. For example, the c-th column Cc and the e-th column Ce can be spaced the same distance from the a-th column Ca, and the number of touch sensors TS arranged in the c-th column Cc can be the same as the number of touch sensors TS arranged in the e-th column Ce.

[0090] The touch sensing unit 20 may include drive signal wirings provided in the touch inactive area NSA and connected to the drive electrode lines TEL in a one-to-one manner. Each of the drive signal wirings may electrically connect the corresponding drive electrode lines TEL to the pads PAD provided in the pad area PADA.

[0091] The touch sensing unit 20 may include sensing signal wirings provided in the touch non-active area NSA and connected to the sensing electrode lines REL in a one-to-one manner. Each of the sensing signal wirings may electrically connect the corresponding sensing electrode lines REL to the pads PAD provided in the pad area PADA.

[0092] The touch sensing unit 20 may include sensing signal wirings respectively connected to the sensing electrode lines REL. Each of the sensing signal wirings may electrically connect the sensing electrode line REL to the pad area PADA.

[0093] The touch electrode TCE of the touch sensor TS and the counter electrode 230 described below (see Figure 19 ) forms a parasitic capacitance between them. When the areas of the touch electrodes TCE included in the touch sensor TS are the same, as shown in FIG. Figure 3 As shown in FIG, because the number of touch sensors TS arranged in columns (or rows) is different from one another, the parasitic capacitance values formed between the touch electrodes TCE of the touch sensors TS arranged in the columns (or rows) and the opposing electrode 230 are different from one another. For example, when the areas of the touch electrodes TCE included in the touch sensors TS are the same, the parasitic capacitance value in the a-th column Ca, which includes more touch sensors TS than other columns, is different from the parasitic capacitance value in the b-th column Cb, which includes fewer touch sensors TS. When the parasitic capacitance values differ from one another depending on the rows (or columns) in which the touch electrodes TCE are arranged, a touch failure may occur.

[0094] According to embodiments of the present disclosure, by forming the touch electrodes TCE of touch sensors TS arranged in different rows or columns to have different areas, differences in parasitic capacitance values within individual columns (or rows) can be reduced. Accordingly, a display device according to embodiments of the present disclosure can prevent or reduce touch failures. Embodiments of the touch sensor TS will be described in more detail below.

[0095] Figure 5 and Figure 6 is schematically shown at Figure 3 Magnified views of the touch sensor at different locations are shown in FIG.

[0096] Figure 5 are respectively shown according to the embodiment Figure 3FIG2 is an enlarged view of the first touch sensor TS1, the second touch sensor TS2, and the third touch sensor TS3. The first touch sensor TS1, the second touch sensor TS2, and the third touch sensor TS3 are arranged in the same row but in different columns. Specifically, the first touch sensor TS1 can be set at the intersection between the a-th column Ca and the p-th row Rp, the second touch sensor TS2 can be set at the intersection between the b-th column Cb and the p-th row Rp, and the third touch sensor TS3 can be set at the intersection between the c-th column Cc and the p-th row Rp.

[0097] Figure 6 are respectively shown according to the embodiment Figure 3 FIG1 is an enlarged view of the first touch sensor TS1, the fourth touch sensor TS4, and the fifth touch sensor TS5. The first touch sensor TS1, the fourth touch sensor TS4, and the fifth touch sensor TS5 are arranged in the same column but in different rows. Specifically, the first touch sensor TS1 may be disposed at the intersection between the a-th column Ca and the p-th row Rp, the fourth touch sensor TS4 may be disposed at the intersection between the a-th column Ca and the s-th row Rs, and the fifth touch sensor TS5 may be disposed at the intersection between the a-th column Ca and the t-th row Rt.

[0098] refer to Figures 3 to 6 , areas of the touch electrodes TCE of the touch sensors TS arranged in different columns may be different from each other, and areas of the touch electrodes TCE of the touch sensors TS arranged in different rows in each column may be the same.

[0099] The unit area of the touch sensor TS disposed at the edge (or corner) of the touch active area SA may be smaller than the unit area of the touch sensor TS disposed at the center of the touch active area SA. This specification will be described by comparing the areas of the touch electrodes TCE of the touch sensors TS having the same unit area. That is, the unit areas of the touch sensors TS of this specification may be the same.

[0100] In an embodiment, the area of the touch electrodes TCE of the touch sensors TS arranged in a column where the sensing electrode lines REL having a relatively large length are positioned may be smaller than the area of the touch electrodes TCE of the touch sensors TS arranged in a column where the sensing electrode lines REL having a relatively small length are positioned. In other words, the area of the touch electrodes TCE of the touch sensors TS arranged in a column where more touch sensors TS are arranged may be smaller than the area of the touch electrodes TCE of the touch sensors TS arranged in a column where fewer touch sensors TS are arranged.

[0101] The area of the touch electrode TCE of the first touch sensor TS1 arranged in the a-th column Ca may be smaller than the area of the touch electrode TCE of the second touch sensor TS2 arranged in the b-th column Cb. The area of the drive electrode TE of the first touch sensor TS1 arranged in the a-th column Ca may be smaller than the area of the drive electrode TE of the second touch sensor TS2 arranged in the b-th column Cb. The area of the sensing electrode RE of the first touch sensor TS1 arranged in the a-th column Ca may be smaller than the area of the sensing electrode RE of the second touch sensor TS2 arranged in the b-th column Cb.

[0102] The area of the touch electrode TCE of the second touch sensor TS2 arranged in the b-th column Cb may be smaller than the area of the touch electrode TCE of the third touch sensor TS3 arranged in the c-th column Cc. The area of the drive electrode TE of the second touch sensor TS2 arranged in the b-th column Cb may be smaller than the area of the drive electrode TE of the third touch sensor TS3 arranged in the c-th column Cc. The area of the sensing electrode RE of the second touch sensor TS2 arranged in the b-th column Cb may be smaller than the area of the sensing electrode RE of the third touch sensor TS3 arranged in the c-th column Cc.

[0103] Each touch sensor TS may further include a first dummy pattern DP1 located between the drive electrode TE and the sensing electrode RE. In an embodiment, the area of the first dummy pattern DP1 arranged in the column where the sensing electrode line REL having a relatively large length is located may be larger than the area of the first dummy pattern DP1 of the touch sensor TS arranged in the column where the sensing electrode line REL having a relatively small length is located. In other words, the area of the first dummy pattern DP1 of the touch sensor TS arranged in the column where more touch sensors TS are located may be larger than the area of the first dummy pattern DP1 of the touch sensor TS arranged in the column where fewer touch sensors TS are located. In an embodiment, the spacing between the drive electrode TE and the sensing electrode RE of the touch sensor TS arranged in the column where more touch sensors TS are located may be larger than the spacing between the drive electrode TE and the sensing electrode RE of the touch sensor TS arranged in the column where fewer touch sensors TS are located.

[0104] The area of the first dummy pattern DP1 of the first touch sensor TS1 may be larger than the area of the first dummy pattern DP1 of the second touch sensor TS2. In an embodiment, in a plan view, the interval G1 between the drive electrode TE and the sensing electrode RE of the first touch sensor TS1 may be larger than the interval G2 between the drive electrode TE and the sensing electrode RE of the second touch sensor TS2. In this specification, the interval between "A" and "B" is defined as the average interval between "A" and "B".

[0105] The area of the first dummy pattern DP1 of the second touch sensor TS2 may be larger than the area of the first dummy pattern DP1 of the third touch sensor TS3. In a plan view, the interval G2 between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2 may be larger than the interval G3 between the driving electrode TE and the sensing electrode RE of the third touch sensor TS3.

[0106] In an embodiment, the area or shape of the touch electrodes TCE of the touch sensors TS arranged in the columns where the sensing electrode lines REL having the same length are positioned may be substantially the same. In other words, the area or shape of the touch electrodes TCE of the touch sensors TS arranged in the columns where the same number of touch sensors TS are positioned may be substantially the same. For example, the area of the touch electrode TCE of the second touch sensor TS2 arranged in the b-th column Cb may be substantially the same as the area of the touch electrode TCE of the 2-1 touch sensor TS2′ arranged in the d-th column Cd. For example, the area of the touch electrode TCE of the third touch sensor TS3 arranged in the c-th column Cc may be substantially the same as the area of the touch electrode TCE of the 3-1 touch sensor TS3′ arranged in the e-th column Ce.

[0107] In an embodiment, areas of touch sensors TS located in different rows in each column may be substantially the same. In an embodiment, areas of the first, fourth, and fifth touch sensors TS1, TS4, and TS5 arranged in the same column may be substantially the same.

[0108] The area of the driving electrode TE of the first touch sensor TS1 arranged in the a-th column Ca and the p-th row Rp may be substantially the same as the area of the driving electrode TE of the fourth touch sensor TS4 arranged in the a-th column Ca and the s-th row Rs. The area of the sensing electrode RE of the first touch sensor TS1 arranged in the a-th column Ca and the p-th row Rp may be substantially the same as the area of the sensing electrode RE of the fourth touch sensor TS4 arranged in the a-th column Ca and the s-th row Rs.

[0109] The area of the driving electrode TE of the fourth touch sensor TS4 arranged in the a-th column Ca and the s-th row Rs may be substantially the same as the area of the driving electrode TE of the fifth touch sensor TS5 arranged in the a-th column Ca and the t-th row Rt. The area of the sensing electrode RE of the fourth touch sensor TS4 arranged in the a-th column Ca and the s-th row Rs may be substantially the same as the area of the sensing electrode RE of the fifth touch sensor TS5 arranged in the a-th column Ca and the t-th row Rt.

[0110] The area of the first dummy pattern DP1 of the first touch sensor TS1 may be substantially the same as the area of the first dummy pattern DP1 of the fourth touch sensor TS4. In a plan view, the interval G1 between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be substantially the same as the interval G4 between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4.

[0111] The area of the first dummy pattern DP1 of the fourth touch sensor TS4 may be substantially the same as the area of the first dummy pattern DP1 of the fifth touch sensor TS5. In a plan view, the interval G4 between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4 may be substantially the same as the interval G5 between the driving electrode TE and the sensing electrode RE of the fifth touch sensor TS5.

[0112] In an embodiment, the touch electrodes TCE of touch sensors TS arranged in rows where drive electrode lines TEL having the same length are positioned may have substantially the same area or shape. In other words, the touch electrodes TCE of touch sensors TS arranged in rows where the same number of touch sensors TS are positioned may have substantially the same area or shape. For example, the touch electrode TCE of the fourth touch sensor TS4 arranged in the s-th row Rs may have substantially the same area as the touch electrode TCE of the 4-1 touch sensor TS4′ arranged in the q-th row Rq. For example, the touch electrode TCE of the fifth touch sensor TS5 arranged in the t-th row Rt may have substantially the same area as the touch electrode TCE of the 5-1 touch sensor TS5′ arranged in the r-th row Rr. Accordingly, the touch electrodes TCE of the first touch sensor TS1, the fourth touch sensor TS4, the fifth touch sensor TS5, the 4-1 touch sensor TS4′, and the 5-1 touch sensor TS5′ arranged in the same column may have substantially the same area.

[0113] Despite Figure 6 , the first touch sensor TS1, the fourth touch sensor TS4, and the fifth touch sensor TS5 arranged in the a-th column Ca are described, but the present disclosure is not limited thereto. For example, the touch sensors TS arranged in different rows in another column may also have substantially the same area. For example, the second touch sensor TS2 located in the b-th column Cb and the p-th row Rp may have an area substantially the same as the area of the touch sensor located in the b-th column Cb and the s-th row Rs and the area of the touch sensor located in the b-th column Cb and the t-th row Rt.

[0114] exist Figure 5 and Figure 6In an embodiment, because the area of the touch electrode TCE in a column in which more touch sensors TS are arranged (for example, the a-th column Ca) is smaller than the area of the touch electrode TCE in a column in which fewer touch sensors TS are arranged (for example, the b-th column Cb), the difference in parasitic capacitance values can be reduced.

[0115] Figure 7 is a schematic diagram showing an embodiment of the Figure 3 An enlarged view of portion "E".

[0116] Figure 8 and Figure 9 is schematically shown at Figure 3 Magnified views of the touch sensor at different locations are shown in FIG. Figure 8 are shown separately Figure 3 FIG. 1 is an enlarged view of the first touch sensor TS1 , the second touch sensor TS2 , and the third touch sensor TS3 . Figure 9 are shown separately Figure 3 FIG. 1 is an enlarged view of the first touch sensor TS1 , the fourth touch sensor TS4 , and the fifth touch sensor TS5 .

[0117] In reference Figure 8 and Figure 9 In the embodiment described, Figures 3 to 6 Similar to the embodiment described above, the areas of the touch electrodes TCE of the touch sensors TS arranged in different columns may be different from each other. In addition, the areas of the touch electrodes TCE of the touch sensors TS arranged in different rows in each column may be the same. Figure 8 and Figure 9 The described embodiments are based on Figures 3 to 6 This is a modified example of the described embodiment, and therefore, duplicate description will be omitted, and differences will be mainly described.

[0118] refer to Figure 3 、 Figure 7 、 Figure 8 and Figure 9 At least some of the touch sensors TS may further include a second dummy pattern DP2 located within the touch electrode TCE. The second dummy pattern DP2 may include a 2-1 dummy pattern DP2a located within the drive electrode TE and a 2-2 dummy pattern DP2b located within the sensing electrode RE. In an embodiment, each of the drive electrode TE and the sensing electrode RE may have a ring shape surrounding the second dummy pattern DP2 located therein.

[0119] In an embodiment, the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where the sensing electrode lines REL having a relatively large length are positioned may be larger than the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where the sensing electrode lines REL having a relatively small length are positioned. In other words, the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where more touch sensors TS are positioned may be larger than the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where fewer touch sensors TS are positioned. Accordingly, the area of the touch electrodes TCE of the touch sensors TS arranged in the column where more touch sensors TS are positioned may be smaller than the area of the touch electrodes TCE of the touch sensors TS arranged in the column where fewer touch sensors TS are positioned.

[0120] The area of the second dummy pattern DP2 of the first touch sensor TS1 arranged in the a-th column Ca may be larger than the area of the second dummy pattern DP2 of the second touch sensor TS2 arranged in the b-th column Cb. The area of the 2-1 dummy pattern DP2a of the first touch sensor TS1 may be larger than the area of the 2-1 dummy pattern DP2a of the second touch sensor TS2. The area of the 2-2 dummy pattern DP2b of the first touch sensor TS1 may be larger than the area of the 2-2 dummy pattern DP2b of the second touch sensor TS2.

[0121] The area of the second dummy pattern DP2 of the second touch sensor TS2 arranged in the b-th column Cb may be larger than the area of the second dummy pattern DP2 of the third touch sensor TS3 arranged in the c-th column Cc. The area of the 2-1 dummy pattern DP2a of the second touch sensor TS2 may be larger than the area of the 2-1 dummy pattern DP2a of the third touch sensor TS3. The area of the 2-2 dummy pattern DP2b of the second touch sensor TS2 may be larger than the area of the 2-2 dummy pattern DP2b of the third touch sensor TS3.

[0122] Since the area of the second dummy pattern DP2 of the first touch sensor TS1 is larger than the area of the second dummy pattern DP2 of the second touch sensor TS2, the area of the touch electrode TCE of the first touch sensor TS1 can be smaller than the area of the touch electrode TCE of the second touch sensor TS2. Similarly, since the area of the second dummy pattern DP2 of the second touch sensor TS2 is larger than the area of the second dummy pattern DP2 of the third touch sensor TS3, the area of the touch electrode TCE of the second touch sensor TS2 can be smaller than the area of the touch electrode TCE of the third touch sensor TS3.

[0123] Despite Figure 7 and Figure 8Each of the touch sensors TS shown in FIG. 1 includes a second dummy pattern DP2, but the present disclosure is not limited thereto. In embodiments, some touch sensors TS may not include the second dummy pattern DP2 and may have a non-annular shape. For example, a touch sensor TS in a column where more touch sensors TS are located may include the second dummy pattern DP2, while a touch sensor TS in a column where fewer touch sensors TS are located may not include the second dummy pattern DP2. For example, the area of the second dummy pattern DP2 of the first touch sensor TS1 may be larger than the area of the second dummy pattern DP2 of the second touch sensor TS2, and the third touch sensor TS3 may not include the second dummy pattern DP2.

[0124] In an embodiment, areas of the second dummy patterns DP2 of the first, fourth, and fifth touch sensors TS1, TS4, and TS5 arranged in the same column may be substantially the same.

[0125] The area of the 2-1 dummy pattern DP2a of the first touch sensor TS1, the area of the 2-1 dummy pattern DP2a of the fourth touch sensor TS4, and the area of the 2-1 dummy pattern DP2a of the fifth touch sensor TS5 may be substantially the same. The area of the 2-2 dummy pattern DP2b of the first touch sensor TS1, the area of the 2-2 dummy pattern DP2b of the fourth touch sensor TS4, and the area of the 2-2 dummy pattern DP2b of the fifth touch sensor TS5 may be substantially the same.

[0126] In an embodiment, the interval between the drive electrode TE and the sensing electrode RE of each of the touch sensors TS may be the same. For example, the interval G1a between the drive electrode TE and the sensing electrode RE of the first touch sensor TS1, the interval G2a between the drive electrode TE and the sensing electrode RE of the second touch sensor TS2, and the interval G3a between the drive electrode TE and the sensing electrode RE of the third touch sensor TS3 may be substantially the same. For example, the interval G1a between the drive electrode TE and the sensing electrode RE of the first touch sensor TS1, the interval G4a between the drive electrode TE and the sensing electrode RE of the fourth touch sensor TS4, and the interval G5a between the drive electrode TE and the sensing electrode RE of the fifth touch sensor TS5 may be substantially the same.

[0127] In other words, the areas of the first dummy patterns DP1 of the touch sensors TS may be substantially the same. For example, the areas of the first dummy patterns DP1 of the first touch sensor TS1, the second touch sensor TS2, and the third touch sensor TS3 may be substantially the same. For example, the areas of the first dummy patterns DP1 of the first touch sensor TS1, the fourth touch sensor TS4, and the fifth touch sensor TS5 may be substantially the same.

[0128] However, this is merely an example, and the present disclosure is not limited thereto. In an embodiment, intervals between the driving electrodes TE and the sensing electrodes RE of the touch sensors TS located in different columns or rows may be different from each other.

[0129] Figure 10 and Figure 11 is a schematic diagram showing a Figure 3 Magnified views of the touch sensor at different locations are shown in FIG. Figure 10 are shown separately Figure 3 FIG. 1 is an enlarged view of the first touch sensor TS1 , the second touch sensor TS2 , and the third touch sensor TS3 . Figure 11 are shown separately Figure 3 FIG. 1 is an enlarged view of the first touch sensor TS1 , the fourth touch sensor TS4 , and the fifth touch sensor TS5 .

[0130] refer to Figure 3 、 Figure 4 、 Figure 10 and Figure 11 , the areas of the touch electrodes TCE of the touch sensors TS arranged in different rows may be different from each other, and the areas of the touch electrodes TCE of the touch sensors TS arranged in different columns in each row may be the same. Figure 10 and Figure 11 The embodiment described is Figures 3 to 6 This is a modified embodiment of the embodiment described in , and therefore duplicate description will be omitted, and differences will be mainly described.

[0131] In an embodiment, areas of the touch electrodes TCE of the first, second, and third touch sensors TS1, TS2, and TS3 arranged in the same row may be substantially the same.

[0132] The driving electrodes TE of the first touch sensors TS1 arranged in the a-th column Ca and the p-th row Rp and the driving electrodes TE of the second touch sensors TS2 located in the b-th column Cb and the p-th row Rp may have substantially the same area. The sensing electrodes RE of the first touch sensors TS1 arranged in the a-th column Ca and the p-th row Rp and the sensing electrodes RE of the second touch sensors TS2 arranged in the b-th column Cb and the p-th row Rp may have substantially the same area.

[0133] The area of the driving electrode TE of the second touch sensor TS2 arranged in the b-th column Cb and the p-th row Rp and the area of the driving electrode TE of the third touch sensor TS3 arranged in the c-th column Cc and the p-th row Rp may be substantially the same. The area of the sensing electrode RE of the second touch sensor TS2 arranged in the b-th column Cb and the p-th row Rp and the area of the sensing electrode RE of the third touch sensor TS3 arranged in the c-th column Cc and the p-th row Rp may be substantially the same.

[0134] In an embodiment, the area of the first dummy pattern DP1 of the first touch sensor TS1 may be substantially the same as the area of the first dummy pattern DP1 of the second touch sensor TS2. In a plan view, the interval G1b between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be substantially the same as the interval G2b between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2.

[0135] The area of the first dummy pattern DP1 of the second touch sensor TS2 may be substantially the same as the area of the first dummy pattern DP1 of the third touch sensor TS3. In a plan view, the interval G2b between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2 may be substantially the same as the interval G3b between the driving electrode TE and the sensing electrode RE of the third touch sensor TS3.

[0136] Despite Figure 10 , the first touch sensor TS1, the second touch sensor TS2, and the third touch sensor TS3 arranged in the p-th row Rp are described, but the present disclosure is not limited thereto. For example, the touch sensors TS in different columns in another row may have substantially the same area. The fourth touch sensor TS4 arranged in the a-th column Ca and the s-th row Rs, the touch sensor arranged in the b-th column Cb and the s-th row Rs, and the touch sensor arranged in the c-th column Cc and the s-th row Rs may have substantially the same area.

[0137] In an embodiment, the area of the touch electrodes TCE of the touch sensors TS arranged in a row where the driving electrode lines TEL having a relatively large length are located may be smaller than the area of the touch electrodes TCE of the touch sensors TS arranged in a row where the driving electrode lines TEL having a relatively small length are located. In other words, the area of the touch electrodes TCE of the touch sensors TS arranged in a row where more touch sensors TS are located may be smaller than the area of the touch electrodes TCE of the touch sensors TS arranged in a row where fewer touch sensors TS are located.

[0138] like Figure 11As shown in , the area of the touch electrode TCE of the first touch sensor TS1 located in the p-th row Rp may be smaller than the area of the touch electrode TCE of the fourth touch sensor TS4 located in the s-th row Rs. The area of the driving electrode TE of the first touch sensor TS1 located in the p-th row Rp may be smaller than the area of the driving electrode TE of the fourth touch sensor TS4 located in the s-th row Rs. The area of the sensing electrode RE of the first touch sensor TS1 located in the p-th row Rp may be smaller than the area of the sensing electrode RE of the fourth touch sensor TS4 located in the s-th row Rs.

[0139] The area of the touch electrode TCE of the fourth touch sensor TS4 located in the s-th row Rs may be smaller than the area of the touch electrode TCE of the fifth touch sensor TS5 located in the t-th row Rt. The area of the drive electrode TE of the fourth touch sensor TS4 located in the s-th row Rs may be smaller than the area of the drive electrode TE of the fifth touch sensor TS5 located in the t-th row Rt. The area of the sensing electrode RE of the fourth touch sensor TS4 located in the s-th row Rs may be smaller than the area of the sensing electrode RE of the fifth touch sensor TS5 located in the t-th row Rt.

[0140] The area of the first dummy pattern DP1 of the first touch sensor TS1 may be larger than the area of the first dummy pattern DP1 of the fourth touch sensor TS4. In a plan view, the interval G1b between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be larger than the interval G4b between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4.

[0141] The area of the first dummy pattern DP1 of the fourth touch sensor TS4 may be greater than the area of the first dummy pattern DP1 of the fifth touch sensor TS5. In a plan view, the interval G4b between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4 may be greater than the interval G5b between the driving electrode TE and the sensing electrode RE of the fifth touch sensor TS5.

[0142] exist Figure 10 and Figure 11 In an embodiment, because the area of the touch electrode TCE arranged in the row where more touch sensors TS are located (for example, the p-th row Rp) is smaller than the area of the touch electrode TCE arranged in the row where fewer touch sensors TS are located (for example, the s-th row Rs), the difference in parasitic capacitance values can be reduced.

[0143] exist Figure 10 and Figure 11In the embodiment, although the areas of the touch electrodes TCE arranged in separate rows are made different by making the areas of the first dummy patterns DP1 arranged in separate rows different from each other, the present disclosure is not limited thereto. Figure 10 and Figure 11 In the embodiment of Figures 7 to 9 Similar to the embodiment of FIG, the touch sensor TS may further include a second dummy pattern DP2, and the area of the touch electrode TCE may be made different using the second dummy pattern DP2. For example, the area of the second dummy pattern DP2 of the touch sensor TS arranged in a row where more touch sensors TS are located may be larger than the area of the second dummy pattern DP2 of the touch sensor TS arranged in a row where fewer touch sensors TS are located.

Figure 13 are shown separately Figure 3 FIG. 1 is an enlarged view of the first touch sensor TS1 , the fourth touch sensor TS4 , and the fifth touch sensor TS5 .

[0146] In reference Figure 12 and Figure 13 In the described embodiment, the areas of the touch electrodes TCE of the touch sensors TS arranged in different columns may be different from each other, and the areas of the touch electrodes TCE of the touch sensors TS arranged in different rows in each column may be different from each other. Figure 12 and Figure 13 The described embodiment is a modified embodiment of the above-described embodiment, and therefore, duplicate descriptions will be omitted, and differences will be mainly described.

[0147] refer to Figure 3 、 Figure 4 、 Figure 12 and Figure 13, the area of the touch electrode TCE of the touch sensor TS arranged in the column where the sensing electrode line REL having a relatively large length is positioned may be smaller than the area of the touch electrode TCE of the touch sensor TS arranged in the column where the sensing electrode line REL having a relatively small length is positioned. In addition, the area of the touch electrode TCE of the touch sensor TS arranged in the row where the driving electrode line TEL having a relatively large length is positioned may be smaller than the area of the touch electrode TCE of the touch sensor TS arranged in the row where the driving electrode line TEL having a relatively small length is positioned. In an embodiment, when the touch effective area SA has a Figure 3 When the touch electrode TCE of the touch sensor TS has a circular shape as shown in , the area of the touch electrode TCE of the touch sensor TS may increase as the touch sensor TS moves away from the center of the touch active area SA.

[0148] In an embodiment, the area of the touch electrodes TCE of the touch sensors TS located in the columns where more touch sensors TS are located may be smaller than the area of the touch electrodes TCE of the touch sensors TS located in the columns where fewer touch sensors TS are located. In addition, the area of the touch electrodes TCE of the touch sensors TS located in the rows where more touch sensors TS are located may be smaller than the area of the touch electrodes TCE of the touch sensors TS located in the rows where fewer touch sensors TS are located.

[0149] like Figure 12 As shown in , the area of the touch electrode TCE of the first touch sensor TS1 arranged in the a-th column Ca may be smaller than the area of the touch electrode TCE of the second touch sensor TS2 arranged in the b-th column Cb. The area of the touch electrode TCE of the second touch sensor TS2 arranged in the b-th column Cb may be smaller than the area of the touch electrode TCE of the third touch sensor TS3 arranged in the c-th column Cc. In addition, as shown in Figure 13 As shown in , the area of the touch electrode TCE of the first touch sensor TS1 arranged in the p-th row Rp may be smaller than the area of the touch electrode TCE of the fourth touch sensor TS4 arranged in the s-th row Rs. The area of the touch electrode TCE of the fourth touch sensor TS4 arranged in the s-th row Rs may be smaller than the area of the touch electrode TCE of the fifth touch sensor TS5 arranged in the t-th row Rt.

[0150] In an embodiment, Figure 12 As shown in , the area of the first dummy pattern DP1 of the first touch sensor TS1 may be larger than the area of the first dummy pattern DP1 of the second touch sensor TS2. The area of the first dummy pattern DP1 of the second touch sensor TS2 may be larger than the area of the first dummy pattern DP1 of the third touch sensor TS3. Figure 13As shown in , the area of the first dummy pattern DP1 of the first touch sensor TS1 may be greater than the area of the first dummy pattern DP1 of the fourth touch sensor TS4. The area of the first dummy pattern DP1 of the fourth touch sensor TS4 may be greater than the area of the first dummy pattern DP1 of the fifth touch sensor TS5.

[0151] like Figure 12 As shown in FIG, in a plan view, the interval G1c between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be greater than the interval G2c between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2. The interval G2c between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2 may be greater than the interval G3c between the driving electrode TE and the sensing electrode RE of the third touch sensor TS3. In addition, as shown in FIG. Figure 13 As shown in FIG, in a plan view, an interval G1c between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be greater than an interval G4c between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4. An interval G4c between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4 may be greater than an interval G5c between the driving electrode TE and the sensing electrode RE of the fifth touch sensor TS5.

[0152] exist Figure 12 and Figure 13 In an embodiment, because the area of the touch electrode TCE in the column where more touch sensors TS are positioned (for example, the a-th column Ca) is smaller than the area of the touch electrode TCE in the column where fewer touch sensors TS are positioned (for example, the b-th column Cb), and the area of the touch electrode TCE in the row where more touch sensors TS are positioned (for example, the p-th row Rp) is smaller than the area of the touch electrode TCE in the row where fewer touch sensors TS are positioned (for example, the s-th row Rs), the difference in parasitic capacitance values can be reduced.

[0153] exist Figure 12 and Figure 13 In the embodiment, although the areas of the touch electrodes TCE arranged in separate rows and columns are made different by making the areas of the first dummy patterns DP1 arranged in separate rows and columns different from each other, the present disclosure is not limited thereto. Figure 12 and Figure 13 In an embodiment, the touch sensor TS may further include a second dummy pattern DP2, and areas of the touch electrodes TCE may be different by using second dummy patterns DP2 having different areas.

[0154] Figure 14 is a schematic diagram showing a Figure 3Magnified views of the touch sensor at different locations are shown in FIG. Figure 14 are shown separately Figure 3 FIG. 1 is an enlarged view of the first touch sensor TS1 , the second touch sensor TS2 , and the third touch sensor TS3 .

[0155] refer to Figure 14 The embodiment described is in Figures 3 to 6 This is a modified embodiment of the embodiment described in , and therefore a detailed description will be omitted, and differences will be mainly described.

[0156] refer to Figure 14 , the area of the touch electrodes TCE of the touch sensors TS arranged in the columns where more touch sensors TS are located may be smaller than the area of the touch electrodes TCE of the touch sensors TS arranged in the columns where fewer touch sensors TS are located. In addition, the intervals between the drive electrodes TE and the sensing electrodes RE of the touch sensors TS arranged in the columns where more touch sensors TS are located may be smaller than the intervals between the drive electrodes TE and the sensing electrodes RE of the touch sensors TS arranged in the columns where fewer touch sensors TS are located.

[0157] Because the interval between the driving electrode TE and the sensing electrode RE is relatively small in the touch sensor TS in which the area of the touch electrode TCE is small, even when the area of the touch electrode TCE is slightly reduced, the change in mutual capacitance between the driving electrode TE and the sensing electrode RE of the touch sensor TS can be smoothly measured.

[0158] In an embodiment, the area of the first dummy pattern DP1 of the touch sensors TS arranged in the column where the sensing electrode lines REL having a relatively large length are positioned may be smaller than the area of the first dummy pattern DP1 of the touch sensors TS arranged in the column where the sensing electrode lines REL having a relatively small length are positioned. In other words, the area of the first dummy pattern DP1 of the touch sensors TS arranged in the column where more touch sensors TS are positioned may be smaller than the area of the first dummy pattern DP1 of the touch sensors TS arranged in the column where fewer touch sensors TS are positioned. In an embodiment, the spacing between the drive electrodes TE and the sensing electrodes RE of the touch sensors TS arranged in the column where more touch sensors TS are positioned may be smaller than the spacing between the drive electrodes TE and the sensing electrodes RE of the touch sensors TS arranged in the column where fewer touch sensors TS are positioned.

[0159] The area of the first dummy pattern DP1 of the first touch sensor TS1 may be smaller than the area of the first dummy pattern DP1 of the second touch sensor TS2. In an embodiment, in a plan view, the interval G1d between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be smaller than the interval G2d between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2.

[0160] The area of the first dummy pattern DP1 of the second touch sensor TS2 may be smaller than the area of the first dummy pattern DP1 of the third touch sensor TS3. In a plan view, the interval G2d between the driving electrode TE and the sensing electrode RE of the second touch sensor TS2 may be smaller than the interval G3d between the driving electrode TE and the sensing electrode RE of the third touch sensor TS3.

[0161] In an embodiment, at least some of the touch sensors TS may include a second dummy pattern DP2 located inside the touch electrode TCE. In an embodiment, some of the touch sensors TS may include the second dummy pattern DP2 inside the touch electrode TCE, while other touch sensors TS may not include the second dummy pattern DP2 inside the touch electrode TCE. That is, while some of the touch sensors TS may include drive electrodes TE and sensing electrodes RE each formed in a ring shape, other touch sensors TS may include drive electrodes TE and sensing electrodes RE each having a non-ring shape.

[0162] In an embodiment, the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where the sensing electrode lines REL having a relatively large length are positioned may be larger than the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where the sensing electrode lines REL having a relatively small length are positioned. In other words, the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where more touch sensors TS are positioned may be larger than the area of the second dummy pattern DP2 of the touch sensors TS arranged in the column where fewer touch sensors TS are positioned. Accordingly, the area of the touch electrodes TCE of the touch sensors TS located in the column where more touch sensors TS are positioned may be smaller than the area of the touch electrodes TCE of the touch sensors TS located in the column where fewer touch sensors TS are positioned.

[0163] The area of the second dummy pattern DP2 of the first touch sensor TS1 arranged in the a-th column Ca may be larger than the area of the second dummy pattern DP2 of the second touch sensor TS2 arranged in the b-th column Cb. The area of the 2-1 dummy pattern DP2a of the first touch sensor TS1 may be larger than the area of the 2-1 dummy pattern DP2a of the second touch sensor TS2. The area of the 2-2 dummy pattern DP2b of the first touch sensor TS1 may be larger than the area of the 2-2 dummy pattern DP2b of the second touch sensor TS2.

[0164] In an embodiment, touch sensors TS arranged in a column where sensing electrode lines REL having a relatively large length are positioned may include a second dummy pattern DP2, while touch sensors TS arranged in a column where sensing electrode lines REL having a relatively small length are positioned may not include the second dummy pattern DP2. In other words, touch sensors TS located in a column where more touch sensors TS are positioned may include the second dummy pattern DP2, while touch sensors TS located in a column where fewer touch sensors TS are positioned may not include the second dummy pattern DP2. For example, the third touch sensor TS3 arranged in the c-th column Cc may not include the second dummy pattern DP2. That is, the third touch sensor TS3 may have a non-annular shape. Even when the interval G3d between the drive electrode TE and the sensing electrode RE is relatively large, the third touch sensor TS3 does not include the second dummy pattern DP2, and therefore, the area of the touch electrode TCE can be relatively large.

[0165] In an embodiment, as referenced Figure 5 and Figure 6 As described, the areas or shapes of the touch electrodes TCE of the touch sensors TS (eg, the first touch sensor TS1 , the fourth touch sensor TS4 , and the fifth touch sensor TS5 ) arranged in different rows in each column may be the same.

[0166] In addition, in the embodiment, as shown in FIG. Figure 12 and Figure 13 As described, the areas of the touch electrodes TCE of the touch sensors TS (eg, the first touch sensor TS1, the fourth touch sensor TS4, and the fifth touch sensor TS5) arranged in different rows in each column may be different from each other. Figure 14As shown in , the interval G1d between the driving electrode TE and the sensing electrode RE of the first touch sensor TS1 may be smaller than the interval G2d between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4, and the area of the second dummy pattern DP2 of the first touch sensor TS1 may be larger than the area of the second dummy pattern DP2 of the fourth touch sensor TS4. For example, the interval G2d between the driving electrode TE and the sensing electrode RE of the fourth touch sensor TS4 may be smaller than the interval G3d between the driving electrode TE and the sensing electrode RE of the fifth touch sensor TS5, and the fifth touch sensor TS5 may not include the second dummy pattern DP2.

[0167] In the embodiment, although the areas and shapes of the touch sensors TS arranged in different columns are described, the present disclosure is not limited thereto. Figure 10 and Figure 11 As shown in , you can modify Figure 14 According to the embodiment shown in , the areas and shapes of the touch electrodes TCE of the touch sensors TS arranged in different rows in each column may be different.

In an embodiment, the first length of the driving electrode lines TEL arranged in the first row R1 to the y-th row Ry may be greater than the second length of the driving electrode lines TEL arranged in the y+1-th row Ry+1 to the n-th row Rn.

[0174] In an embodiment, the number of touch sensors TS arranged in one of the first to y-th rows R1 to Ry may be greater than the number of touch sensors TS arranged in one of the y+1-th to n-th rows Ry+1. For example, the number of touch sensors TS located in the p-th row Rp may be greater than the number of touch sensors TS located in the q-th row Rq (p is a natural number equal to or greater than 1 and equal to or less than y, and q is a natural number ranging from y+1 to n).

[0175] The sensing electrode line REL may include at least two sensing electrode lines REL having different lengths. Figure 15 As shown in , the touch active area SA may include sensing electrode lines REL having a third length in the first column C1 to the x-th column Cx, and may include sensing electrode lines REL having a fourth length in the x+1-th column Cx+1 to the m-th column Cm (x is a natural number equal to or greater than 1 and equal to or less than m). In an embodiment, the third length of the sensing electrode lines REL arranged in the first column C1 to the x-th column Cx may be greater than the fourth length of the sensing electrode lines REL arranged in the x+1-th column Cx+1 to the m-th column Cm.

[0176] In an embodiment, the number of touch sensors TS arranged in one of the first to xth columns C1 to Cx may be greater than the number of touch sensors TS arranged in one of the x+1th to mth columns Cx+1 to Cm. For example, the number of touch sensors TS located in the ath column Ca may be greater than the number of touch sensors TS located in the bth column Cb (a is a natural number equal to or greater than 1 and equal to or less than x, and b is a natural number ranging from x+1 to m).

In other words, the area of the touch electrode TCE of the touch sensor TS located in a column where more touch sensors TS are located (for example, one of the first column C1 to the x-th column Cx) may be smaller than the area of the touch electrode TCE of the touch sensor TS located in a column where fewer touch sensors TS are located (for example, one of the x+1-th column Cx+1 to the m-th column Cm).

In other words, the area of the first dummy pattern DP1 of the touch sensors TS arranged in the column where more touch sensors TS are positioned may be larger than the area of the first dummy pattern DP1 of the touch sensors TS arranged in the column where fewer touch sensors TS are positioned. In an embodiment, the interval between the drive electrode TE and the sensing electrode RE of the touch sensors TS located in the column where more touch sensors TS are positioned may be larger than the interval between the drive electrode TE and the sensing electrode RE of the touch sensors TS located in the column where fewer touch sensors TS are positioned.

The area of the sensing electrode RE of the first touch sensor TS1a located in the p-th row Rp may be smaller than the area of the sensing electrode RE of the third touch sensor TS3a located in the q-th row Rq.

[0193] In an embodiment, the area of the first dummy pattern DP1 of the touch sensors TS arranged in a row where a driving electrode line TEL having a relatively large length is positioned may be larger than the area of the first dummy pattern DP1 of the touch sensors TS arranged in a row where a driving electrode line TEL having a relatively small length is positioned. In other words, the area of the first dummy pattern DP1 of the touch sensors TS located in a row where more touch sensors TS are positioned may be larger than the area of the first dummy pattern DP1 of the touch sensors TS located in a row where fewer touch sensors TS are positioned. In an embodiment, the spacing between the driving electrodes TE and sensing electrodes RE of the touch sensors TS located in a row where more touch sensors TS are positioned may be larger than the spacing between the driving electrodes TE and sensing electrodes RE of the touch sensors TS located in a row where fewer touch sensors TS are positioned.

[0198] Figure 18 is a schematic diagram showing a Figure 15 Magnified views of the touch sensor at different locations are shown in FIG.

[0199] refer to Figure 4 、 Figure 15 and Figure 18 , areas of the touch electrodes TCE of the touch sensors TS arranged in different columns may be different from each other, and areas of the touch electrodes TCE of the touch sensors TS arranged in different rows may be different from each other.

[0200] In an embodiment, the area of the touch electrode TCE of the touch sensor TS arranged in a column where more touch sensors TS are located (for example, one of the first column C1 to the x-th column Cx) may be smaller than the area of the touch electrode TCE of the touch sensor TS arranged in a column where fewer touch sensors TS are located (for example, one of the x+1-th column Cx+1 to the m-th column Cm). In addition, the area of the touch electrode TCE of the touch sensor TS arranged in a row where more touch sensors TS are located (for example, one of the first row R1 to the y-th row Ry) may be smaller than the area of the touch electrode TCE of the touch sensor TS arranged in a row where fewer touch sensors TS are located (for example, one of the y+1-th row Ry+1 to the n-th row Rn).

[0201] That is, the area of the touch electrode TCE of the touch sensor TS located at the intersection between the column where more touch sensors TS are located (for example, one of the first column C1 to the x-th column Cx) and the row where more touch sensors TS are located (for example, one of the first row R1 to the y-th row Ry) can be smaller than the area of the touch electrode TCE of the touch sensor TS located in the remaining area.

[0202] For example, the area of the touch electrode TCE of the first touch sensor TS1a located at the intersection between the a-th column Ca, which is one of the first to x-th columns C1 to Cx, and the p-th row Rp, which is one of the first to y-th rows R1 to Ry, can be smaller than the area of the touch electrode TCE of the second touch sensor TS2a located at the intersection between the b-th column Cb, which is one of the x+1-th to m-th columns Cx+1 to Cm, and the p-th row Rp. The area of the drive electrode TE of the first touch sensor TS1a can be smaller than the area of the drive electrode TE of the second touch sensor TS2a. The area of the sensing electrode RE of the first touch sensor TS1a can be smaller than the area of the sensing electrode RE of the second touch sensor TS2a.

[0203] For example, the area of the touch electrode TCE of the first touch sensor TS1a located at the intersection between the a-th column Ca, which is one of the first to x-th columns C1 to Cx, and the p-th row Rp, which is one of the first to y-th rows R1 to Ry, may be smaller than the area of the touch electrode TCE of the third touch sensor TS3a located at the intersection between the a-th column Ca and the q-th row Rq, which is one of the y+1-th to n-th rows Ry+1. The area of the drive electrode TE of the first touch sensor TS1a may be smaller than the area of the drive electrode TE of the third touch sensor TS3a. The area of the sensing electrode RE of the first touch sensor TS1a may be smaller than the area of the sensing electrode RE of the third touch sensor TS3a.
