[0061] In the following description, for the purpose of explanation, many specific details are set forth to provide a thorough understanding of various exemplary embodiments or implementations of the invention. "Embodiment" and "implementation" as used herein are interchangeable words for non-limiting examples of devices or methods using one or more inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments may be implemented without these specific details or with one or more equivalent arrangements. In other cases, in order to avoid making various exemplary embodiments unnecessarily obscure, well-known structures and devices are shown in block diagram form. In addition, various exemplary embodiments may be different, but need not be exclusive. For example, without departing from the inventive concept, the specific shape, construction and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0062] Unless otherwise specified, the illustrated exemplary embodiments will be understood as providing exemplary features of different details of some ways in which the inventive concept can be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter, individually or collectively referred to as "elements" or "multiple elements") of the various embodiments may be further combined, separated, interchanged and / or rearranged without departing from the inventive concept.

[0063] The use of cross hatching and / or shadows is usually provided in the drawings to make the boundaries between adjacent elements clear. In this way, unless otherwise specified, the presence and absence of cross hatching or shadows do not express or represent any preference or requirement for the specific material, material properties, size, ratio, commonality between the elements shown and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the drawings, the size and relative size of the elements can be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiment can be implemented differently, the specific process sequence can be performed in a different order from that described. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same reference numerals represent the same elements.

[0064] When an element or layer is referred to as being "on" another element or layer, "connected to" or "bonded to" another element or layer, the element or layer may be directly on, directly connected to or directly bonded to the other element or layer, or there may be an intermediate element or layer. However, when an element or layer is referred to as being "directly on" another element or layer, "directly connected to" or "directly bonded to" another element or layer, there is no intermediate element or layer. For this reason, the term "connection" may refer to a physical connection, electrical connection and / or fluid connection in the presence or absence of an intermediate element. In addition, the D1 axis, the D2 axis and the D3 axis are not limited to the three axes of a rectangular coordinate system (such as an x-axis, a y-axis and a z-axis), and may be interpreted in a broader sense. For example, the D1 axis, the D2 axis and the D3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as any combination of only X, only Y, only Z, or two or more of X, Y, and Z, such as, for example, XYZ, XYY, YZ, and ZZ. As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items.

[0065] Although the terms "first", "second", etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, the first element discussed below may be named as the second element without departing from the disclosed teachings.

[0066] For descriptive purposes, spatially relative terms such as "under," "below," "below," "down," "above," "up," "above," "higher," "side" (e.g., as in "sidewall"), etc., may be used herein to describe the relationship of one element to another (other) element as shown in the accompanying drawings. Spatially relative terms are intended to include different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, elements or features described as "under" or "beneath" other elements or features will subsequently be positioned as "above" the other elements or features. Thus, the exemplary term "under" can include both above and below orientations. In addition, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), so the spatially relative descriptors used herein are interpreted accordingly.

[0067] The terms used herein are for the purpose of describing specific embodiments, and are not intended to be limited. As used herein, unless the context clearly indicates otherwise, the singular forms "one", "one (kind / person)" and "the (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, elements, components and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, elements, components and / or their groups. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms rather than as terms of degree, so that they are used to explain the inherent deviations of measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0068] Various exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views that are schematic diagrams of idealized exemplary embodiments and / or intermediate structures. As such, variations in the shapes of the illustrations, such as those caused by manufacturing techniques and / or tolerances, are expected to occur. Therefore, the exemplary embodiments disclosed herein should not necessarily be construed as being limited to the shapes of the specifically illustrated regions, but rather will include deviations in shape caused by, for example, manufacturing. In this manner, the regions illustrated in the accompanying drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and as such, are not necessarily intended to be limiting.

[0069] As is customary in the art, some exemplary embodiments are described and shown in the accompanying drawings in the form of functional blocks, units and / or modules. It will be appreciated by those skilled in the art that these functional blocks, units and / or modules are physically implemented by electronic (or optical) circuits such as logic circuits, discrete components, microprocessors, hard-wired circuits, memory elements, wiring connections, etc., which can be formed using semiconductor-based manufacturing techniques or other manufacturing techniques. In the case where the functional blocks, units and / or modules are implemented by microprocessors or other similar hardware, they can be programmed and controlled using software (e.g., microcode) to perform the various functions discussed herein, and they can be optionally driven by firmware and / or software. It is also contemplated that each functional block, unit and / or module can be implemented by dedicated hardware, or as a combination of dedicated hardware that performs certain functions and processors (e.g., one or more programmed microprocessors and related circuits) that perform other functions. In addition, without departing from the scope of the inventive concept, each functional block, unit and / or module of some exemplary embodiments can be physically separated into two or more interactive and discrete functional blocks, units and / or modules. Furthermore, the functional blocks, units and / or modules of some exemplary embodiments may be physically combined into more complex functional blocks, units and / or modules without departing from the scope of the inventive concept.

[0070] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this disclosure is a part. Terms (such as those defined in general dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an ideal or overly formal sense unless expressly defined as such herein.

[0071] Figure 1 is a perspective view of a display device DD according to an exemplary embodiment of the inventive concept. Figure 1 , the display device DD can display the image IM through the display surface DD-IS. The display surface DD-IS is parallel to the surface defined by the first direction axis DR1 and the second direction axis DR2. The normal direction of the display surface DD-IS (ie, the thickness direction of the display device DD) is represented as the third direction axis DR3.

[0072] The front surface (or top surface) and the rear surface (or bottom surface) of each member or unit described below are distinguished by the third directional axis DR3. However, the first directional axis to the third directional axis DR1, DR2, DR3 shown in this embodiment may be just an example. Hereinafter, the first direction to the third direction may be directions indicated by the first directional axis to the third directional axis DR1, DR2, DR3, respectively, and indicated by the same reference numerals.

[0073] Although a display device DD having a flat display surface is shown in the exemplary embodiment of the inventive concept, the exemplary embodiment of the inventive concept is not limited thereto. The display device DD may include a curved display surface or a stereoscopic display surface. The stereoscopic display surface may include a plurality of display areas indicating different directions. For example, the stereoscopic display surface may include a polygonal columnar display surface.

[0074] The display device DD according to the current embodiment may be a rigid display device. However, the exemplary embodiments of the inventive concept are not limited thereto. For example, the display device DD according to the inventive concept may be a flexible display device DD. The flexible display device DD may include a foldable display device or a belt-type display device whose partial area is bendable.

[0075] According to this embodiment, a display device DD that can be applied to a mobile terminal is exemplarily shown. Although not shown, an electronic module, a camera module, a power module, etc. mounted on a main board may be provided on a frame / casing together with the display device DD to constitute a mobile terminal. The display device DD according to an exemplary embodiment of the inventive concept may be applied to large-sized electronic devices such as televisions and monitors, and small and medium-sized electronic devices such as tablet PCs, navigation units for vehicles, game consoles, and smart watches.

[0076] like Figure 1 As shown in , the display surface DD-IS includes an image area DD-DA in which the image IM is displayed and a bezel area DD-NDA adjacent to the image area DD-DA. The bezel area DD-NDA may be an area in which no image is displayed. Figure 1 An icon is shown as an example of the image IM.

[0077] like Figure 1 As shown in , the image area DD-DA may have a substantially rectangular shape. The “substantially rectangular shape” includes not only a rectangular shape as a mathematical meaning but also a rectangular shape in which no vertices are defined in a vertex area (or corner area) but a boundary of a curve is defined.

[0078] The frame area DD-NDA may surround the image area DD-DA. However, exemplary embodiments of the inventive concept are not limited thereto. For example, the shapes of the image area DD-DA and the frame area DD-NDA may be designed in a related manner.

[0079] FIG. 2A to FIG. 2D is a cross-sectional view of a display device DD according to an exemplary embodiment of the inventive concept. FIG. 2A to FIG. 2D The cross section defined by the second direction axis DR2 and the third direction axis DR3 is shown. FIG. 2A to FIG. 2DTo explain the stacking relationship of the functional components constituting the display device DD.

[0080] A display device DD according to an exemplary embodiment of the inventive concept may include a display panel, an input sensor, an anti-reflector, and a window. At least some of the display panel, the input sensor, the anti-reflector, and the window may be formed by a continuous process and at least some of them may be bonded to each other by an adhesive member. FIG. 2A to FIG. 2D An optically clear adhesive OCA is shown as an example of a bonding member. Hereinafter, the bonding member may include a common adhesive or bonding agent. In an exemplary embodiment of the inventive concept, the anti-reflector and the window may be replaced by different components or the anti-reflector and the window may be omitted.

[0081] exist FIG. 2A to FIG. 2D In the embodiment of the present invention, the corresponding components among the input sensor, the anti-reflector, and the window formed by a continuous process relative to other components may be represented as a "layer". In addition, the components among the input sensor, the anti-reflector, and the window bonded to other components by bonding members may be represented as a "panel". The "panel" may include a substrate layer providing a substrate surface, such as a synthetic film, a composite film, a glass substrate, etc., but the substrate layer may be omitted in the "layer". That is, the unit represented as a "layer" may be provided on a substrate surface provided by other units.

[0082] Here, the input sensor, the anti-reflector, and the window may be referred to as an input sensing panel ISP, an anti-reflection panel RPP, and a window panel WP, or an input sensing layer ISL, an anti-reflection layer RPL, and a window layer WL.

[0083] like Figure 2A As shown in , the display device DD may include a display panel DP, an input sensing layer ISL, an anti-reflection panel RPP, and a window panel WP. The input sensing layer ISL may be directly disposed on the display panel DP. In this specification, "component B is directly disposed on component A" may mean that a separate adhesive layer / adhesive member is not disposed between component A and component B. After component A is formed, component B may be formed on a substrate surface provided by component A through a continuous process.

[0084] The display panel DP and the input sensing layer ISL disposed directly on the display panel DP may be defined as a display module DM. An optically clear adhesive OCA is disposed between the display module DM and the anti-reflection panel RPP and between the anti-reflection panel RPP and the window panel WP.

[0085] The display panel DP generates an image, and the input sensing layer ISL acquires coordinate information of an external input (e.g., a touch event). Although not separately shown, the display module DM according to an exemplary embodiment of the inventive concept may further include a protective member disposed on the bottom surface of the display panel DP. The protective member and the display panel DP may be bonded to each other by an adhesive member. FIG. 2B to FIG. 2D The display device DD may further include a protective member.

[0086] The display panel DP according to the exemplary embodiment of the inventive concept may be an emissive display panel, but is not limited thereto. For example, the display panel DP may be an organic light-emitting display panel or a quantum dot light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include an organic light-emitting material. The light-emitting layer of the quantum dot light-emitting display panel may include quantum dots, quantum rods, etc. Hereinafter, the organic light-emitting display panel will be described as an example of the display panel DP.

Fig.7I yes Fig. 7A Hereinafter, the details of the area BB will be omitted. 6A to 6F The components described are the same as the detailed descriptions of the components.

[0156] Reference Fig. 7A , the sensing area IS-DA may be divided into a plurality of first sensing areas S1 and a plurality of second sensing areas S2. The plurality of first sensing areas S1 and the plurality of second sensing areas S2 may be distinguished from each other by virtual lines. The plurality of first sensing areas S1 may be areas to which the same rule (hereinafter, referred to as the first rule) is applied, and may be a part of an area in which the first electrode group EG1 and the second electrode group EG2 are disposed. The plurality of second sensing areas S2 may be areas to which the same rule (hereinafter, referred to as the second rule) different from the first rule is applied, and may be a part of an area in which the first electrode group EG1 and the second electrode group EG2 are disposed.

[0157] The first sensing areas S1 and the second sensing areas S2 that are alternately disposed may be arranged in a p×q matrix. Here, each of p and q is a natural number of 5 or more.

[0158] Will refer to FIG. 7B to FIG. 7D Describe the first rule. Figure 7BAs shown in, the first sensing region S1 includes a first connection portion CP1, a half of the first sensing portion SP1 disposed on one side of the first connection portion CP1 in the second direction DR2, and the other half of the first sensing portion SP1 disposed on the other side of the first connection portion CP1 in the second direction DR2. The first sensing region S1 includes a second connection portion CP2, a half of the second sensing portion SP2 disposed on one side of the second connection portion CP2 in the first direction DR1, and the other half of the second sensing portion SP2 disposed on the other side of the second connection portion CP2 in the first direction DR1. In this embodiment, a first sensing region S1 in which two second connection portions CP2 are disposed is shown as an example. The second connection portion CP2 may be disposed on a layer different from the layer of the first sensing portion SP1, the first connection portion CP1, and the second sensing portion SP2, and, for example, formed by a first conductive layer IS-CL1 (see Fig. 6A In this embodiment, the second connection portion CP2 may be defined as a bridge pattern.

[0159] Reference Figure 7C , a plurality of emission regions PXA-R, PXA-B, and PXA-G are disposed in the first sensing region S1. The emission regions disposed in the first sensing region S1 having the plurality of emission regions PXA-R, PXA-B, and PXA-G may be defined as a first emission region group.

[0160] The emission regions PXA-R, PXA-B, and PXA-G of the first emission region group include unit cells CU1 and CU2 arranged in an n×n matrix, where n is a natural number of 10 or more. n may be an odd number.

[0161] A first row 1stL, an n-th row n-thL, a second row 2ndL, a first column 1stC, a second column 2ndC, and an n-th column n-thC are schematically shown. The unit cell includes a first unit cell CU1 and a second unit cell CU2.

[0162] Each first unit cell CU1 includes first and third emission regions PXA-R and PXA-G arranged in a diagonal direction (or fourth direction) DR4. Each second unit cell CU2 includes second and third emission regions PXA-B and PXA-G arranged in a diagonal direction DR4.

[0163] The first unit cell CU1 and the second unit cell CU2 of the first emission region group have a first arrangement. In each of the rows arranged in an n×n matrix, the first unit cell CU1 and the second unit cell CU2 are alternately arranged. When the first unit cell of the odd row is the first unit cell CU1, the first unit cell of the even row may be the second unit cell CU2.

[0164] like Figure 7C As shown in , the first unit cell of the first row 1stL of the first emission region group may be the first unit cell CU1, and the n-th unit cell of the first row 1stL may be the first unit cell CU1. The first unit cell of the last row of the first emission region group may be the first unit cell CU1, and the n-th unit cell of the n-th row n-thL may be the first unit cell CU1. Figure 7C As shown in , the first emission region of the first emission region row corresponding to the first sensing region S1 may be the first emission region PXA-R.

[0165] The first unit cell CU1 and the second unit cell CU2 of the first emission region group may have the same first arrangement as the first opening OP-MR, the second opening OP-MB, and the third opening OP-MG provided in the first sensing region S1. This is because the first opening OP-MR, the second opening OP-MB, and the third opening OP-MG correspond one-to-one to the first emission region PXA-R, the second emission region PXA-B, and the third emission region PXA-G.

[0166] Reference Fig.7D The two second connection portions CP2 connect the two second sensing portions SP2 spaced apart from each other. The first to fourth connection regions CNT-A1 to CNT-A4 are each disposed between the two second connection portions CP2 and between the two second sensing portions SP2.

[0167] The contact hole CNT-I may be defined in each of the first to fourth connection regions CNT-A1 to CNT-A4. The first to second connection regions CNT-A1 to CNT-A2 may be both disposed by using the second emission region PXA-B as a center, and the third to fourth connection regions CNT-A3 to CNT-A4 may be both disposed by using the first emission region PXA-R as a center.

[0168] The second connection portion CP2 and the grid line of the first sensing portion SP1 (eg, Fig. 6E The second connection portion CP2 may be replaced by the grid lines of the first sensing portion SP1 inside the intersection area. The grid lines of the second connection portion CP2 and the grid lines of the first sensing portion SP1 may not overlap each other except for the intersection point. The grid lines of the second connection portion CP2 and the grid lines of the first sensing portion SP1 may define an opening replaced by the first opening OP-MR, the second opening OP-MB, and the third opening OP-MG.

[0169] Will refer to FIG. 7E to FIG. 7G Describe the second rule. Fig. 7E The second sensing area S2 has Figure 7B The structure of the first sensing area S1 is similar to that of Figure 7F , the emission regions disposed in the second sensing region S2 having the plurality of emission regions PXA-R, PXA-B, and PXA-G may be defined as a second emission region group.

[0170] The emission regions PXA-R, PXA-B, and PXA-G of the second emission region group include first unit cells CU1 and second unit cells CU2 arranged in an n×n matrix. The first unit cells CU1 and the second unit cells CU2 of the second emission region group have different Figure 7C A second arrangement of the first arrangement described.

[0171] The second layout and Figure 7C The first arrangement is different in that the positions of the first unit cell CU1 and the second unit cell CU2 are exchanged. When the first unit cell of the odd-numbered row is the second unit cell CU2, the first unit cell of the even-numbered row may be the first unit cell CU1.

[0172] like Figure 7F As shown in , the first unit cell of the first row 1stL of the second emission region group may be the second unit cell CU2, and the n-th unit cell of the first row 1stL may be the second unit cell CU2. The first unit cell of the n-th row n-thL of the second emission region group may be the second unit cell CU2, and the n-th unit cell of the n-th row n-thL may be the second unit cell CU2. Figure 7F As shown in , the first emission region of the first emission region row corresponding to the second sensing region S2 may not be the first emission region PXA-R but the second emission region PXA-B.

[0173] The first and second unit cells CU1 and CU2 of the second emission region group having the second arrangement may have the same meaning as the first, second, and third openings OP-MR, OP-MB, and OP-MG disposed in the second sensing region S2 having the second arrangement.

[0174] Reference Figure 7G , the two second connection portions CP2 connect halves of the two second sensing portions SP2 to each other. The intersection region S2-CA of the second sensing region S2 may have a structure similar to the intersection region S1-CA of the first sensing region S1.

[0175] Reference Figure 7G, the first connection region CNT-A1 to the fourth connection region CNT-A4 are all disposed between the two second connection portions CP2 and between the two second sensing portions SP2. The first connection region CNT-A1 and the second connection region CNT-A2 may be disposed by using the first emission region PXA-R as the center, and the third connection region CNT-A3 and the fourth connection region CNT-A4 may be disposed by using the second emission region PXA-B as the center.

[0176] like Figure 7C and Figure 7F As shown in FIG, the reason why the first emission region group and the second emission region group adjacent to each other in the same row have emission arrangements different from each other is because the first emission region group and the second emission region group have odd rows and even rows, respectively. In addition, this is because the reference Fig. 6E The described arrangement of the first type emission area row PL1 , the second type emission area row PL2 , and the third type emission area row PL3 is repeated.

[0177] In an exemplary embodiment of the inventive concept, although the first emission region group and the second emission region group do not have odd-numbered rows and even-numbered rows, referring to Fig. 6E The described arrangement relationship between the first emission region PXA-R, the second emission region PXA-B, and the third emission region PXA-G may be changed to achieve the same result.

[0178] Reference Figure 7C and Figure 7F , a boundary between the first sensing portion SP1 and the second sensing portion SP2 may be defined by a disconnection point of the grid lines. Figure 7C The disconnection point of the first sensing portion SP1 and the second sensing portion SP2 may be defined Figure 7H The first border pattern BP1 is formed. Figure 7F The disconnection point of the first sensing portion SP1 and the second sensing portion SP2 may be defined Figure 7H The first and second boundary patterns BP1 and BP2 may connect the disconnected points to each other at the shortest distance.

[0179] The first boundary pattern BP1 and the second boundary pattern BP2 have different shapes from each other. As described above, the openings OP-MR, OP-MB, and OP-MG of the first sensing region S1 or the emission regions PXA-R, PXA-B, and PXA-G may have a first arrangement, and the openings OP-MR, OP-MB, and OP-MG of the second sensing region S2 or the emission regions PXA-R, PXA-B, and PXA-G may have a second arrangement.

[0180] In addition, due to the above reasons, the grid lines of the first sensing area S1 have a first shape, and the grid lines of the second sensing area S2 have a second shape different from the first shape. Since the openings OP-MR, OP-MB, and OP-MG are defined by the grid lines, the grid lines may need to be deformed to change the arrangement of the openings OP-MR, OP-MB, and OP-MG.

[0181] like Fig.7I As shown in , the input sensor IS may further include a dummy pattern DDP insulated from the first electrodes IE1-1 to IE1-10 of the first electrode group EG1 and the second electrodes IE2-1 to IE2-8 of the second electrode group EG2. The dummy pattern DDP may be a floating pattern spaced apart from the sensing electrode. The dummy pattern DDP may be disposed on the same layer as the first sensing portion SP1 and the second sensing portion SP2. In this embodiment, the dummy pattern DDP may be formed by the second conductive layer CL2.

[0182] The dummy pattern DDP can be set by referring to Fig. 7A The center of the area defined by the (k,j) sensing area, (k+1,j) sensing area, (k,j+1) sensing area, and (k+1,j+1) sensing area in the sensing areas arranged in a p×q matrix is ​​described. Wherein, k is a natural number of p or less, and j is a natural number of q or less. The dummy pattern DDP may be disposed on the boundaries of the four sensing areas adjacent to each other to reduce the parasitic capacitance between the electrodes disposed in different rows and different columns.

Figure 8C is a plan view of an input sensor IS according to an exemplary embodiment of the inventive concept. FIG. 6A to FIG. 7I The components described are the same as the detailed descriptions of the components.

[0184] like Fig. 8A and Figure 8B As shown in , the sensing area IS-DA may include an inner sensing area IS-DA1 and an outer sensing area IS-DA2 disposed outside the inner sensing area IS-DA1. FIG. 6A to FIG. 7I As described, the internal sensing area IS-DA1 may be divided into a plurality of first sensing areas S1 and a plurality of second sensing areas S2.

[0185] The external sensing area IS-DA2 may further include several groups of sensing areas. The external sensing area IS-DA2 may further include a third sensing area S3 and a fourth sensing area S4. The third sensing area S3 and the fourth sensing area S4 may have the same surface area, and may have a surface area different from the surface area of ​​the first sensing area S1. Similar to the embodiment, each of the third sensing area S3 and the fourth sensing area S4 may have a surface area smaller than the surface area of ​​the first sensing area S1.

[0186] The third sensing region S3 may be disposed adjacent to the first sensing region S1, and the fourth sensing region S4 may be disposed adjacent to the second sensing region S2. The third sensing region S3 is disposed continuously outside the first sensing region S1. The fourth sensing region S4 is disposed continuously outside the second sensing region S2.

[0187] Set up with multiple emission areas PXA-R, PXA-B and PXA-G (see Fig. 6E ) may be defined as a third emission region group. An emission region disposed in a fourth sensing region S4 having a plurality of emission regions PXA-R, PXA-B, and PXA-G may be defined as a fourth emission region group.

[0188] The openings OP-MR, OP-MB, and OP-MG defined in the third sensing region S3 may have the same FIG. 6A to FIG. 7I Since the surface area of ​​the third sensing region S3 is smaller than the surface area of ​​each of the first sensing region S1 and the second sensing region S2, the third sensing region S3 may include a small number of openings OP-MR, OP-MB, and OP-MG (see Fig. 6E ).

[0189] The openings OP-MR, OP-MB and OP-MG defined in the fourth sensing region S4 (see Fig. 6E ) can have the same FIG. 6A to FIG. 7I A fourth arrangement is described which is different from the first and second arrangements.

[0190] The fourth arrangement is different from the third arrangement. This will refer to Figure 7C , Figure 7F and Figure 8B Describe. Figure 7C As shown in , since the first unit cell of the first row 1stL of the first emission region group is the first unit cell CU1, the nth unit cell of the first row of the third emission region group is the second unit cell CU2. Figure 7FAs shown in , since the first unit cell of the first row 1stL of the second emission region group is the second unit cell CU2, the nth unit cell of the first row of the fourth emission region group is the first unit cell CU1. As described above, the unit cells arranged at the corresponding positions of the third emission region group and the fourth emission region group are different from each other. The unit cells arranged at the corresponding positions are different from each other and the openings OP-MR, OP-MB and OP-MG defined at the corresponding positions are different from each other.

[0191] The external sensing area IS-DA2 may further include a fifth sensing area S5, a sixth sensing area S6, and a seventh sensing area S7. In the fifth sensing area S5 and the sixth sensing area S6, the openings OP-MR, OP-MB, and OP-MG have an arrangement different from the first arrangement and the second arrangement, just like the third sensing area S3 and the fourth sensing area S4. The fifth sensing area S5 and the sixth sensing area S6 may be disposed below the first sensing area S1 and the second sensing area S2, respectively. The surface area of ​​the seventh sensing area S7 may be smaller than the surface area of ​​each of the other sensing areas S1 to S6.

[0192] like Figure 8C As shown in FIG. , the sensing area IS-DA may include a first internal sensing area IS-DA10 and a second sensing area IS-DA20. FIG. 6A to FIG. 7I As described, the first internal sensing area IS-DA10 may be divided into a plurality of first sensing areas S1 and a plurality of second sensing areas S2.

[0193] The second sensing area IS-DA20 may be divided into a plurality of third sensing areas S3 and a plurality of fourth sensing areas S4. The surface areas of the third sensing areas S3 and the fourth sensing areas S4 are the same as those of the first sensing areas S1 and the second sensing areas S2.

[0194] The third sensing region S3 may be disposed adjacent to the first sensing region S1, and the fourth sensing region S4 may be disposed adjacent to the second sensing region S2. Fig. 6E ) may be defined as a third emission region group. An emission region in a fourth sensing region S4 disposed in the plurality of emission regions PXA-R, PXA-B, and PXA-G may be defined as a fourth emission region group.

[0195] The openings OP-MR, OP-MB, and OP-MG defined in the third sensing region S3 may have the same FIG. 6A to FIG. 7I However, the boundary pattern of the third sensing area S3 (hereinafter, referred to as the third boundary pattern) may have the same Figure 7H The shape of each of the first and second boundary patterns BP1 and BP2 may be different. That is, the grid lines of the third sensing area S3 may have a third shape different from each of the first and second shapes.

[0196] The openings OP-MR, OP-MB, and OP-MG defined in the fourth sensing region S4 may have the same FIG. 6A to FIG. 7I However, the boundary pattern of the fourth sensing area S4 (hereinafter, referred to as the fourth boundary pattern) may have the same Figure 7H The shape of each of the first and second boundary patterns BP1 and BP2 may be different. That is, the grid lines of the fourth sensing region S4 may have a fourth shape different from each of the first and second shapes.

[0197] In this embodiment, the openings OP-MR, OP-MB, and OP-MG defined in each third sensing region S3 may have a different arrangement from the openings OP-MR, OP-MB, and OP-MG defined in each fourth sensing region S4. Therefore, the third shape may be different from the fourth shape.

The notch area NTA may be defined in each of the display panel DP and the input sensing layer ISL. Here, the notch areas NTA do not need to be the same. The notch area NTA may be defined in a central portion in the second direction DR2. However, exemplary embodiments of the inventive concept are not limited to the notch area NTA defined in the central portion.

The arrangement and layout of the first signal line group SG1 and the second signal line group SG2 may be different from those of FIG. Figure 6B The setting and arrangement of the input sensing layer ISL are basically the same.

[0211] like Fig. 10B As shown in , due to the formation of the notch area NTA, the tenth first electrode IE1-10 may be divided into two parts. The two parts may be connected to each other through a dummy connection line DSL. Each of the fourth to sixth second electrodes IE2-4 to IE2-6 of the second electrode group EG2 may have a length smaller than that of each of the other electrodes.

A portion of the sensing area adjacent to the hole area HA may be divided into sensing areas different from the first sensing area S1 and the second sensing area S2.

[0218] According to exemplary embodiments, since the sensing electrode is completely disposed in the sensing region, input sensing reliability may be improved.

[0219] Two sensing areas may be provided to improve the degree of freedom in design of the input sensor. Although the grid lines provided in the two sensing areas have shapes different from each other, a sensing deviation may be minimized.
