[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 of the invention. "Embodiment" as used herein is a non-limiting example of a device or method using one or more of the inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments may be practiced without these specific details or in the case of one or more equivalent arrangements. In other cases, in order to avoid unnecessarily obscuring various exemplary embodiments, 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 exemplary embodiments shown will be understood as providing exemplary features of the details of the changes in some ways of implementing the inventive concept 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") 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 shading is usually provided in the drawings to make the boundaries between adjacent elements clear. Thus, unless otherwise specified, the presence and absence of cross hatching or shading do not express or indicate 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 may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments may be implemented differently, the specific process sequence may be performed in a different order than described. For example, two processes described in succession may 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, an electrical connection and / or a fluid connection with or without 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), but 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 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," and "side" (e.g., as in "sidewall") 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 encompass 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, an element 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), and as such, the spatially relative descriptors used herein are interpreted accordingly.

[0067] The terms used here are for the purpose of describing specific embodiments, and are not intended to be limited. As used here, unless the context clearly indicates otherwise, the singular forms "one", "one (kind / person)" and "said (the)" are also intended to include plural forms. And when the terms "comprise" and / or "include" 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 here, 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 due to, 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] 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 commonly used 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 explicitly defined as such herein.

[0070] Figure 1 is a perspective view of a display device according to an embodiment of the inventive concept. Figure 1 , the display device DD may display an image IM through the front surface IS. The front surface IS is parallel to a surface defined by the first direction axis DR1 and the second direction axis DR2.

[0071] The normal direction of the front surface IS (for example, the thickness direction of the display device DD) is indicated as the third directional axis DR3. The front surface (or top surface) and the rear surface (or bottom surface) of each member or unit (which will be described below) are distinguished by the third directional axis DR3. However, the first directional axis to the third directional axis DR1, DR2 and DR3 shown in this exemplary embodiment are only examples. Hereinafter, the first direction to the third direction may be directions indicated by the first directional axis to the third directional axis DR1, DR2 and DR3, respectively, and represented by the same reference numerals.

[0072] Although a display device DD having a flat front surface is shown in the exemplary embodiment of the inventive concept, the inventive concept is not limited thereto. The display device DD may include a curved front surface or a stereoscopic front surface. The stereoscopic front surface may include a plurality of display areas indicating different directions. For example, the stereoscopic front surface may include a polygonal column-shaped front surface.

[0073] The display device DD according to the current exemplary embodiment may be a rigid display device. However, the inventive concept is not limited thereto. For example, the display device DD according to the inventive concept may be a flexible display device DD. According to this exemplary embodiment, a display device DD that can be applied to a mobile terminal is exemplarily shown.

[0074] Although in Figure 1 Although not shown, the electronic module, camera module, power module, etc. mounted on the main board may be arranged on a bracket / housing together with the display device DD to constitute a mobile terminal. The display device DD according to the inventive concept may be applied to large 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.

[0075] Reference Figure 1 , the front surface IS of the display device DD includes an active area AA and a peripheral area NAA adjacent to the active area AA. In this exemplary implementation, the active area AA may be an area on which an image IM is displayed and an external input TC is also sensed.

[0076] The image IM includes a static image and a dynamic image. Figure 1 An icon image is shown as an example of the image IM.

[0077] The external input TC includes a user's input TC applied from the outside. The user's input TC includes various types of external inputs such as a part of the user's body, light, heat, or pressure, etc. In this exemplary embodiment, the user's input TC is illustrated as a user's hand applied to the front surface IS.

[0078] However, this is only an example. For example, the display device DD may sense a user's input TC applied to a side surface or a rear surface of the display device DD. Here, the active area AA may extend to a side surface or a rear surface of the display device DD. The display device DD according to the inventive concept may be designed to have various shapes, but is not limited to a specific embodiment.

[0079] The peripheral area NAA is an area on which the image IM is not displayed or on which the external input TC is not sensed even if an electrical signal is applied. Figure 1 As shown in , the active area AA may have a rectangular shape. The peripheral area NAA may surround the active area AA. However, the inventive concept is not limited thereto. For example, the active area AA and the peripheral area NAA may be designed differently relative to each other.

[0080] FIG. 2A to FIG. 2D is a cross-sectional view of a display device according to an exemplary embodiment of the inventive concept. FIG. 2A to FIG. 2D A cross section defined by the second direction axis DR2 and the third direction axis DR3 is shown. FIG. 2A to FIG. 2D It is simply shown to explain the lamination relationship of the functional panels and / or functional units constituting the display device DD.

[0081] The display device DD according to an exemplary embodiment of the inventive concept may include a display unit, an input sensing unit, an anti-reflection unit, and a window. At least portions of the display unit, the input sensing unit, the anti-reflection unit, and the window may be formed by a continuous process, and at least portions 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 an adhesive member. Hereinafter, the adhesive member may include a general adhesive or a bonding agent. In the inventive concept, the anti-reflection unit and the window may be replaced with different constituent components or completely omitted.

[0082] exist FIG. 2A to FIG. 2D In the text, the corresponding constituent components of the input sensing unit, the anti-reflection unit and the window formed by a continuous process relative to another constituent component can be expressed as a "layer". The constituent components of the input sensing unit, the anti-reflection unit and the window bonded to another constituent component by an adhesive member can be expressed as a "panel". The "panel" may include a substrate layer such as a synthetic film, a composite material film and a glass substrate that provides a substrate surface, but the substrate layer may be omitted in the "layer". That is, the unit expressed as a "layer" may be arranged on a substrate surface provided by other units.

[0083] The display unit, the input sensing unit, the anti-reflection unit and the window may be referred to as a display panel DP, an input sensing panel ISP, an anti-reflection panel RPP and a window panel WP or a display panel DP, an input sensing layer ISL, an anti-reflection layer RPL and a window layer WL.

[0084] 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 is directly disposed on the display panel DP. In this disclosure, "constituent component B is directly disposed on constituent component A" may mean that no separate adhesive layer / adhesive member is disposed between constituent components A and B. Constituent component B may be formed on a substrate surface provided by constituent component A through a continuous process after constituent component A is formed.

[0085] The display panel DP and the input sensing layer ISL directly disposed 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.

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 dot light-emitting elements such as quantum dots and quantum rods. Hereinafter, the display panel DP may be described as an organic light-emitting display panel.

[0088] The anti-reflection panel RPP reduces the reflection of external light incident from the upper side of the window panel WP. The anti-reflection panel RPP according to an exemplary embodiment of the inventive concept may include a retarder and a polarizer. The retarder may be a film-type or liquid crystal coating type retarder, and may include a λ / 2 retarder and / or a λ / 4 retarder. The polarizer may also be a film-type or liquid crystal coating type polarizer. The film type may include an elongated synthetic resin, and the liquid crystal coating type may include liquid crystals arranged in a predetermined arrangement. Each of the retarder and the polarizer may also include a protective film. The retarder and the polarizer themselves or the protective film may be defined as a base layer of the anti-reflection panel RPP.

[0089] The anti-reflection panel RPP according to an exemplary embodiment of the inventive concept may include a color filter. The color filter may have a predetermined arrangement. The arrangement of the color filter may be determined in consideration of the color of the emitted light of the pixel disposed in the display panel DP. The anti-reflection panel RPP may further include a black matrix adjacent to the color filter.

[0090] The anti-reflection panel RPP according to an exemplary embodiment of the inventive concept may include a destructive interference structure. For example, the destructive interference structure includes a first reflective layer and a second reflective layer disposed on different layers from each other. The first reflected light reflected from the first reflective layer and the second reflected light reflected from the second reflective layer may destructively interfere, thereby reducing the reflection of external light.

[0091] The window panel WP according to an exemplary embodiment of the inventive concept includes a base layer WP-BS and a light blocking pattern WP-BZ. The base layer WP-BS may include a glass substrate and / or a synthetic film. The base layer WP-BS is not limited to a single layer. The base layer WP-BS may include two or more films bonded to each other by an adhesive member.

[0092] The light blocking pattern WP-BZ partially overlaps the base layer WP-BS. The light blocking pattern WP-BZ is disposed on the rear surface of the base layer WP-BS, specifically, corresponding to the peripheral area NAA of the display device DD. The area in which the light blocking pattern WP-BZ is not disposed may correspond to the active area AA of the display device DD.

[0093] The light blocking pattern WP-BZ may be, for example, a colored organic film formed in a coating manner. Although not shown, the window panel WP may further include a functional coating layer disposed on the entire surface of the base layer WP-BS. The functional coating layer may include an anti-fingerprint layer, an anti-reflection layer, a hard coating layer, and the like. FIG. 2B to FIG. 2D , the window panel WP and the window layer WL will be simply illustrated without distinguishing the base layer WP-BS and the light blocking pattern WP-BZ from each other.

[0094] like Figure 2B and Figure 2C As shown in , the display device DD may include a display panel DP, an input sensing panel ISP, an anti-reflection panel RPP, and a window panel WP. The lamination order of the input sensing panel ISP and the anti-reflection panel RPP may be changed.

[0095] like Figure 2DAs shown in , the display device DD may include a display panel DP, an input sensing layer ISL, an anti-reflection layer RPL, and a window layer WL. The bonding member may be omitted from the display device DD, and the input sensing layer ISL, the anti-reflection layer RPL, and the window layer WL may be formed on a substrate surface disposed on the display panel DP by a continuous process. The lamination order of the input sensing layer ISL and the anti-reflection layer RPL may be changed.

The display panel DP may correspond to a display unit to be described later. In this exemplary embodiment, "a certain region corresponds to a certain region" may mean that the two regions overlap each other and have the same surface area, but the description is not limited thereto. This will be described in detail later.

The display area AA1 may be an area on which the image IM is displayed, and the non-display area NAA1 may be an area on which the image IM is not displayed. Figure 1 The active area AA corresponds to the peripheral area NAA. In this exemplary embodiment, “a certain area corresponds to a certain area” may mean that the two areas overlap each other and have the same surface area, but is not limited thereto.

[0099] The base layer BL may include at least one plastic film. The base layer BL may include at least one of a plastic substrate, a glass substrate, a metal substrate, and an organic / inorganic composite substrate.

Figure 6B is a plan view of an input sensing unit according to an exemplary embodiment of the inventive concept. Figure 6C It is shown Figure 6B An enlarged plan view of a portion of the area. Fig.6D is a plan view of an input sensing unit according to an exemplary embodiment of the inventive concept. FIG. 6A to FIG. 6D To describe the present disclosure.

[0126] like Fig. 6A As shown in , the input sensing unit ISU may include a first insulating layer IS-IL1, a first conductive layer IS-CL1, a second insulating layer IS-IL2, a second conductive layer IS-CL2, and a third insulating layer IS-IL3. The first insulating layer IS-IL1 may be directly disposed on the upper insulating layer TFL. In the inventive concept, the first insulating layer IS-IL1 may be omitted.

[0127] Each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 may have a single-layer structure or a multi-layer structure in which a plurality of layers are stacked along the third directional axis DR3.

The transparent conductive layer may include at least one of indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium tin zinc oxide (ITZO), PEDOT, metal nanowires, and graphene. The metal layer may be formed of at least one of molybdenum, silver, titanium, copper, aluminum, and alloys thereof. For example, each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 may have a three-layer metal structure, for example, a three-layer structure of titanium / aluminum / titanium.

[0128] Each of the first conductive layer IS-CL1 and the second conductive layer IS-CL2 may include a plurality of conductive patterns. Hereinafter, an example in which the first conductive layer IS-CL1 includes a plurality of first conductive patterns and the second conductive layer IS-CL2 includes a plurality of second conductive patterns will be described. Each of the first conductive patterns and the second conductive patterns may include a sensing electrode and a signal line connected to the sensing electrode.

[0129] Each of the first insulating layer IS-IL1 and the second insulating layer IS-IL2 may include an inorganic material or an organic material.

The organic material may include at least one of acrylic resin, methacrylic resin, polyisoprene resin, vinyl resin, epoxy resin, urethane resin, cellulose resin, siloxane resin, polyimide resin, polyamide resin, and perylene resin.

[0130] Reference Figure 6B and Figure 6C , the input sensing unit ISU is disposed on the base substrate BS. The input sensing unit ISU may be disposed on the display unit DPU or the display panel DP, may be disposed between the display unit DPU and the base substrate BS, or may be disposed to be separated from the display unit DPU and to place the base substrate BS between the input sensing unit ISU and the display unit DPU.

[0131] The input sensing unit ISU provides a front surface IS2 including a sensing area AA2 and a second peripheral area NAA2. The sensing area AA2 may be connected to the display device DD (see Figure 1 ) effective area AA (see Figure 1 ). The second peripheral area NAA2 may correspond to the peripheral area NAA of the display device DD (see Figure 1 ) corresponds. In this exemplary embodiment, the display area AA1 (see Figure 3A ) and sensing area AA2 may correspond to each other.

[0132] However, this is only an example. For example, the display area AA1 and the sensing area AA2 may partially overlap each other. The active area AA may be an area substantially defined by projecting the display area AA1 and the sensing area AA2. Therefore, the active area AA may include all of the display area AA1 and the sensing area AA2.

[0133] The input sensing unit ISU includes a plurality of first electrodes TE1, a plurality of second electrodes TE2, a plurality of third electrodes TE3, a plurality of sensing lines TL11, TL12, TL2, and TL3, and a plurality of sensing pads T11, T12, T2, and T3. For ease of description, portions of the electrodes are illustrated as hatched so that the first electrodes TE1, the second electrodes TE2, and the third electrodes TE3 are distinguished from each other.

[0134] The first electrode TE1, the second electrode TE2, and the third electrode TE3 are disposed in the sensing area AA2. As described above, the sensing area AA2 may overlap the display area AA1 of the display unit DPU and may correspond to the active area AA of the display device DD.

[0135] Sensing lines TL11, TL12, TL2 and TL3 and sensing pads T11, T12, T2 and T3 are disposed in the second peripheral area NAA2. As described above, the second peripheral area NAA2 may overlap the first peripheral area NAA1 of the display unit DPU and may correspond to the peripheral area NAA of the display device DD.

[0136] The sensing lines TL11, TL12, TL2, and TL3 may include a plurality of first sensing lines TL11 and TL12, a plurality of second sensing lines TL2, and a third sensing line TL3. The sensing pads T11, T12, T2, and T3 include a plurality of first sensing pads T11 and T12, a plurality of second sensing pads T2, and a third sensing pad T3. The sensing lines TL11, TL12, TL2, and TL3 are connected to corresponding pads among the sensing pads T11, T12, T2, and T3, respectively.

[0137] The first electrodes TE1 are arranged in the first direction DR1. Each of the first electrodes TE1 extends in the second direction DR2. Each of the first electrodes TE1 may include a plurality of first main patterns SP1 and a plurality of first connection patterns BP1.

[0138] Each of the first main patterns SP1 and the first connection patterns BP1 may be arranged in the second direction DR2. Each of the first main patterns SP1 has a rhombus shape. However, this is only an example. For example, each of the first main patterns SP1 is not limited to a specific shape.

[0139] Each of the first connection patterns BP1 is disposed between the first main patterns SP1. Each of the first connection patterns BP1 connects two first main patterns SP1 adjacent to each other. The first main patterns SP1 are electrically connected through the first connection patterns BP1.

[0140] In this exemplary embodiment, the first connection patterns BP1 are disposed on a layer different from that of the first main pattern SP1. Each of the first connection patterns BP1 may partially overlap the first main pattern SP1. Each of the first main patterns SP1 may be electrically connected to the first connection pattern BP1 by passing through a predetermined insulating layer.

[0141] The first sensing lines TL1 are respectively connected to the first electrodes TE1. The first sensing lines TL1 respectively connect the first electrodes TE1 to pads of the first sensing pads T11 and T12 corresponding to the first electrodes TE1.

[0142] In this exemplary embodiment, the first sensing line TL1 may include a first sub-line TL11 and a second sub-line TL12. The first sub-line TL11 connects a portion of the first electrode TE1 to a portion T11 of the first sensing pads T11 and T12. The second sub-line TL12 connects the remaining portion of the first electrode TE1 to the remaining portion T12 of the first sensing pads T11 and T12.

[0143] For ease of description, Figure 6C Three first sensing lines L11, L12, and L13 of the first sensing line TL1 are shown The three sensing lines L11, L12, and L13 are connected to corresponding first electrodes TE1, respectively.

[0144] The first sensing line TL1 may transmit the electrical signals provided through the first sensing pads T11 and T12 to the first electrode TE1, respectively, or may transmit the electrical signals provided from the first electrode TE1 to the outside through the first sensing pads T11 and T12. However, this is only an example. For example, the first sensing pads T11 and T12 may be continuously arranged on one side of the signal pad DPD, but the inventive concept is not limited to this specific arrangement.

[0145] Refer again Figure 6B and Figure 6C , the second electrodes TE2 are arranged in the second direction DR2. Each of the second electrodes TE2 extends in the first direction DR1. Each of the second electrodes TE2 may include a plurality of second main patterns SP2 and a plurality of second connection patterns BP2.

[0146] Each of the second main pattern SP2 and the second connection pattern BP2 may be arranged in the first direction DR1. Each of the first main pattern SP1 and the second main pattern SP2 has a rhombus shape. However, this is only an example. For example, in the inventive concept, the shape of each of the first main pattern SP1 and the second main pattern SP2 is not limited thereto.

[0147] Each of the second connection patterns BP2 is disposed between the second main patterns SP2. Each of the second connection patterns BP2 connects two second main patterns SP2 adjacent to each other. The second main patterns SP2 are electrically connected through the second connection patterns BP2.

[0148] In this exemplary embodiment, the second connection pattern BP2 is disposed on the same layer as the second main pattern SP2 and is thus disposed as a single body. Therefore, the second electrode TE2 may be disposed as a single body extending in the first direction DR1. However, this is only an example. For example, the second connection pattern BP2 may be disposed on a layer different from that of the second main pattern SP2, but the inventive concept is not limited thereto.

[0149] The second sensing lines TL2 are respectively connected to the second electrodes TE2. The second sensing lines TL2 connect the second electrodes TE2 to the second sensing pads T2.

[0150] For ease of description, Figure 6C N second sensing lines L21, L22, L23, L24, ... and L2N of the second sensing line TL2 are shown. The second sensing lines L21, L22, L23, L24, ... and L2N are respectively connected to corresponding second electrodes TE2. The number N may correspond to the number of second electrodes TE2 provided in the input sensing unit ISU.

[0151] The second sensing line TL2 may transmit an electrical signal provided through the second sensing pad T2 to the second electrode TE2 , or may transmit an electrical signal provided from the second electrode TE2 to the outside through the second sensing pad T2 .

[0152] The second electrode TE2 may receive an electrical signal different from the electrical signal applied to the first electrode TE1. Here, the second electrode TE2 may generate an electric field together with the first electrode TE1. For example, the first electrode TE1 may receive a driving signal and the second electrode TE2 may receive a sensing signal. The input sensing unit ISU may operate in a mutual capacitance manner in which an external input TC is sensed by a change in capacitance formed between the second electrode TE2 and the first electrode TE1 (see FIG. 1 ). Figure 1 ).

[0153] Alternatively, the second electrode TE2 may receive the same type of electrical signal as the first electrode TE1. For example, the first electrode TE1 and the second electrode TE2 may receive a sensing signal. The input sensing unit ISU may operate in a self-capacitance manner in which information of the external input TC is sensed by a change in a sensing signal according to the external input TC.

[0154] Refer again Figure 6B and Figure 6C , the third electrodes TE3 are arranged in the second direction DR2. Each of the third electrodes TE3 extends in the first direction DR1. In this exemplary embodiment, the third electrodes TE3 may extend and be arranged parallel to the second electrodes TE2.

[0155] Each of the third electrodes TE3 may include a plurality of third main patterns SP3 and a plurality of third connection patterns BP3. Each of the third main patterns SP3 and the third connection patterns BP3 may be arranged in the first direction DR1.

[0156] The third main pattern SP3 may be disposed inside the second main pattern SP2. In this exemplary embodiment, the third main patterns SP3 may be disposed in predetermined openings SP-OP respectively defined in the second main patterns SP2, respectively.

[0157] The third main pattern SP3 may be accommodated in the opening SO-OP and may be separated from the second main pattern SP2 in a plan view. In this exemplary embodiment, the third main pattern SP3 and the second main pattern SP2 may not overlap each other in a plan view. In this exemplary embodiment, each of the third main patterns SP3 may be surrounded by each of the second main patterns SP2.

[0158] Each of the third main patterns SP3 may include a first portion (or referred to as a central portion) MP and a second portion (or referred to as a branch portion) PP. The first portion MP may have a shape similar to that of each of the second main patterns SP2. In this exemplary embodiment, the first portion MP may be in a rhombus shape having a size smaller than that of each of the second main patterns SP2.

[0159] The second portion PP is connected to one side of the first portion MP. As an example, the second portion PP may have a rod shape extending in the first direction DR1. In this exemplary embodiment, the second portion PP may be provided in plural and may be connected to two sides opposite to each other in the first direction DR1.

[0160] Each of the third connection patterns BP3 is disposed between the third main patterns SP3. Each of the third connection patterns BP3 connects two third main patterns SP3 adjacent to each other. The third main patterns SP3 are electrically connected through the third connection patterns BP3. However, this is only an example. For example, the third electrode TE3 may be arranged in the first direction DR1, but the inventive concept is not limited thereto.

[0161] The third connection pattern BP3 may be spaced apart from the first connection pattern BP1 in a plan view. The third connection pattern BP3 may be disposed so that the third connection pattern BP3 does not overlap with the first connection pattern BP1 in a plan view. Each of the third connection patterns BP3 according to this exemplary embodiment may have a shape bent (folded) at least once in the first direction DR1. In this exemplary embodiment, each of the third connection patterns BP3 has a shape bent once.

[0162] In a plan view, each of the third connection patterns BP3 may be spaced apart from the first connection pattern BP1 by its bent shape, thereby overlapping the first main pattern SP1. Because each of the third connection patterns BP3 according to the inventive concept has a bent shape, the third connection pattern BP3 may be stably connected to the third main pattern SP3 without interfering with the first connection pattern BP1.

[0163] The third sensing lines TL3 are respectively connected to the third electrodes TE3. The third sensing lines TL3 connect the third sensing pads T3 to the third electrodes TE3. In this exemplary embodiment, each of the third sensing pads T3 and the third sensing lines TL3 is provided as a single body. The third electrode TE3 may receive a ground voltage through the third sensing pads T3.

[0164] According to an exemplary embodiment of the inventive concept, the input sensing unit ISU may further include a third electrode TE3 receiving a ground voltage. Therefore, a signal failure such as noise in the input sensing unit ISU due to an electrical signal provided to the display unit DPU may be prevented from occurring. Therefore, degradation of the sensitivity of the input sensing unit ISU may be easily prevented.

[0165] In addition, according to the inventive concept, the third connection pattern BP3 constituting the third electrode TE3 can be designed so that the third connection pattern BP3 does not overlap the first connection pattern BP1 disposed on the same layer to prevent the third electrode TE3 and the first electrode TE1 from interfering with each other. Therefore, the electrical reliability of the input sensing unit ISU can be improved.

[0166] like Fig.6D As shown in , in the input sensing unit ISU, each of the third sensing line TL3 and the third sensing pad T3 may be provided in plurality. The plurality of third sensing units TL3P and the plurality of third sensing pads T3 may be connected to corresponding third electrodes TE3, respectively. Here, the third electrode TE3 may receive an electrical signal for sensing noise in the active area AA. According to the inventive concept, the input sensing unit ISU may be designed in various structures, but the inventive concept is not limited thereto.

[0167] Figure 7 is a plan view illustrating a portion of an input sensing unit according to an exemplary embodiment of the inventive concept. Fig. 8A and Figure 8B is a cross-sectional view illustrating a portion of an input sensing unit according to an exemplary embodiment of the inventive concept. Figure 7 Shows Figure 6C of area AA'. Fig. 8A Shown along Figure 7 The cross section taken along line I-I', Figure 8B Shown along Figure 7 In the following, reference will be made to Figures 7 to 8B To describe the present disclosure. Figures 1 to 6D The same components may be given the same reference numerals, and their detailed description will be omitted.

[0168] For ease of description, Figure 7A region is shown in which one first connection pattern BP1 , one second connection pattern BP2 , and one third connection pattern BP3 are disposed.

[0169] The first main pattern SP1 and the second main pattern SP2 may be disposed on the same layer and may be spaced apart from each other. A predetermined space GS1 may be defined between the first main pattern SP1 and the second main pattern SP2. Although not shown, a floating pattern spaced apart from the first main pattern SP1 and the second main pattern SP2 may be further disposed in the spaced apart space GS1 between the first main pattern SP1 and the second main pattern SP2.

[0170] The second main pattern SP2 and the third main pattern SP3 may be disposed on the same layer and may be spaced apart from each other. In this exemplary embodiment, the third main pattern SP3 may be disposed in predetermined openings SP-OP defined in the second main pattern SP2, respectively. Therefore, a predetermined space GS2 may be defined between the second main pattern SP2 and the third main pattern SP3. In a plan view, the second main pattern SP2 and the third main pattern SP3 may not overlap each other.

[0171] In this exemplary embodiment, the first connection pattern BP1 may be disposed on a layer different from those of the first main pattern SP1, the second main pattern SP2, the second connection pattern BP2, and the third main pattern SP3 with a predetermined insulating layer SIL therebetween.

[0172] The first connection pattern BP1 is disposed on a layer different from that of the second connection pattern BP2. In this exemplary embodiment, the first connection pattern BP1 may cross the second connection pattern BP2 in a plan view. The first connection pattern BP1 may be connected to the first main pattern SP1 through a contact portion CNT1 passing through the insulating layer SIL.

[0173] The third connection pattern BP3 and the first connection pattern BP1 may be disposed on the same layer. The third connection pattern BP3 may be connected to the third main pattern SP3 through a contact portion CNT3 passing through the insulating layer SIL.

[0174] The third connection pattern BP3 may be spaced apart from the first connection pattern BP1 in a plan view. The third connection pattern BP3 may not overlap the first connection pattern BP1. As described above, the third connection pattern BP3 may be bent in the first direction DR1 in a plan view to be spaced apart from the first connection pattern BP1, thereby overlapping the first main pattern SP1.

[0175] According to the inventive concept, even if the third connection pattern BP3 is disposed on the same layer as the first connection pattern BP1, the third connection pattern BP3 can be connected to the third main pattern SP3 and the first main pattern SP1 without any possibility of being electrically shorted with respect to each other. Therefore, the electrical reliability of the input sensing unit ISU can be improved.

[0176] Fig. 9 is a plan view illustrating a portion of an input sensing unit according to an exemplary embodiment of the inventive concept. FIG. 10A to FIG. 10C is a plan view showing a portion of an input sensing unit according to an exemplary embodiment of the inventive concept. For ease of description, Fig. 9 Shown with Figure 7 The area corresponding to the area FIG. 10A to FIG. 10C Shows Fig. 9 In the following, reference will be made to Figures 9 to 10C To describe the inventive concept. Figures 1 to 8B The same components are given the same reference numerals, and their detailed description will be omitted.

[0177] like Fig. 9 As shown in FIG. 1 , the input sensing unit ISU_M may include a plurality of grid lines MSL. The grid lines MSL include a first grid line MS1 and a second grid line MS2, which extend in a direction crossing the first direction DR1 and the second direction DR2 and cross each other. A predetermined opening MS_OP (hereinafter, referred to as a grid opening) is defined in the grid lines MSL. Each of the grid openings MS_OP may be aligned with the emission area PXA described above (see FIG. 1 ). Figure 5A ). Therefore, even if the grid line MSL is made of an optically opaque material, the influence of the input sensing unit ISU_M on the emission area PXA can be minimized to prevent the degradation of the display characteristics of the display device.

[0178] The grid line MSL may be a constituent component of each of the first electrode TE1_M, the second electrode TE2_M, and the third electrode TE3_M. Specifically, each of the first main pattern SP1_M, the second main pattern SP2_M, the third main pattern SP3_M, and the second connection pattern BP2_M may include the grid line MSL. The cutout space of the grid line MSL may define a boundary between the first main pattern SP1_M, the second main pattern SP2_M, the third main pattern SP3_M, and the second connection pattern BP2_M.

[0179] The first connection pattern BP1_M may be disposed in plurality in the first direction DR1. The first connection pattern BP1_M may include a portion bent in the second direction DR2. Therefore, the first connection pattern BP1_M may not overlap the second connection pattern BP2_M in a plan view, and may overlap the second main pattern SP2_M in a plan view.

[0180] The third connection pattern BP3_M is disposed to be spaced apart from the first connection pattern BP1_M. The third connection pattern BP3_M may be disposed in plurality in the second direction DR2. The third connection pattern BP3_M may include a portion bent along the first direction DR1. Therefore, the third connection pattern BP3_M may not overlap the second connection pattern BP2_M and the first connection pattern BP1_M in a plan view, and may overlap the first main pattern SP1_M in a plan view.

[0181] According to the inventive concept, the first connection pattern BP1_M and the third connection pattern BP3_M are disposed on a layer different from that of the mesh line MSL. FIG. 10A to FIG. 10C , the first connection pattern BP1_M and the third connection pattern BP3_M may constitute a first layer LY1 , ​​the mesh line MSL may constitute a third layer LY3 , and the contact parts CNT1_M and CNT3_M may constitute a second layer LY2 .

[0182] Specifically, the first connection pattern BP1_M and the third connection pattern BP3_M are disposed on the first layer LY1. The first layer LY1 may be disposed on the insulating layer SIL (see Fig. 8A The first connection pattern BP1_M and the third connection pattern BP3_M may be separated from the first main pattern SP1_M, the second main pattern SP2_M, the third main pattern SP3_M, and the second connection pattern BP2_M and then disposed as different layers.

[0183] The first connection pattern BP1_M and the third connection pattern BP3_M may extend along the grid line MSL. Each of the first connection pattern BP1_M and the third connection pattern BP3_M may have a shape corresponding to the grid line MSL. Therefore, each of the first connection pattern BP1_M and the third connection pattern BP3_M may have a shape formed by removing a portion of the grid line MSL. Therefore, the influence of the first connection pattern BP1_M and the third connection pattern BP3_M on the emission region PXA may be reduced.

[0184] The second layer LY2 may correspond to the insulating layer SIL. The insulating layer SIL in which the contact parts CNT1_M and CNT3_M are defined may be disposed on the first connection pattern BP1_M and the third connection pattern BP3_M. The contact parts CNT1_M and CNT3_M may be defined as passing through an area in which a connection between the insulating layer SIL and the mesh line MSL is required in an area overlapping the first connection pattern BP1_M and the third connection pattern BP3_M.

[0185] The third layer LY3 may be a layer disposed on the insulating layer SIL. The grid line MSL is disposed on the insulating layer SIL. That is, each of the first main pattern SP1_M, the second main pattern SP2_M, the third main pattern SP3_M, and the second connection pattern BP2_M may be disposed on the uppermost layer of the input sensing unit ISU_M.

The floating pattern FL may be disposed in a predetermined opening defined in the first main pattern SP1_M. The floating pattern FL is disposed to be separated from the first main pattern SP1_M. According to the inventive concept, since the floating pattern FL is further disposed, it may be difficult to distinguish the second electrode TE2_M1 and the first electrode TE1_M disposed on the third main pattern SP3_M from each other. Therefore, the visibility of the input sensing unit ISU_M may be improved.

[0187] In addition, according to the inventive concept, since the floating pattern FL is further provided, the sensitivity of the input sensing unit ISU_M may be prevented from being degraded according to the electrical signal applied to the display unit DPU. Therefore, the electrical reliability of the input sensing unit ISU_M may be improved.

Fig. 12C Shows Fig.11 In the following, reference will be made to Figures 11 to 12CTo describe the inventive concept. Figures 1 to 10C The same components are given the same reference numerals, and their detailed description will be omitted.

[0189] Fig.11 A portion of the region of the input sensing unit ISU_M1 is shown based on the region on which the first connection pattern BP1_M1, the second connection pattern BP2_M1, and the third connection pattern BP3_M1 are disposed.

For example, the first connection patterns BP1_M1 may be provided in plurality spaced apart from each other in the second direction DR2 to be respectively connected to the first main patterns SP1_M1.

[0191] Each of the first connection patterns BP1_M1 extends along a portion of the grid line MSL. Therefore, each of the first connection patterns BP1_M1 may not overlap the grid opening MS_OP and substantially expose the emission area PXA. Therefore, degradation of the display characteristics of the display device due to lamination of the input sensing unit ISU_M may be prevented.

[0192] The third connection pattern BP3_M1 extends along a portion of the mesh line MSL The third connection pattern BP3_M1 may be spaced apart from the first connection pattern BP1_M1 in a plan view.

The third connection pattern BP3_M1 may have a shape bent at least once along the first direction DR1. In this embodiment, the third connection pattern BP3_M1 may have a zigzag shape bent several times along the first direction DR1. According to the inventive concept, since the third connection pattern BP3_M1 is designed to have a bent shape, the non-overlapping portion between the third connection pattern BP3_M1 and the first connection pattern BP1_M1 may be increased, thereby easily preventing interference with the emission region PXA.

[0195] Reference Fig.11 and Fig. 12C , each of the third main patterns SP3_M1 may include a first portion MP1 and a second portion PP1. Each of the first portion MP1 and the second portion PP1 may be disposed to be spaced apart from the second main pattern SP2_M1 by a predetermined distance.

[0196] The second portion PP1 may have a shape that is bent at least once along the first direction DR1. The second portion PP1 according to this exemplary embodiment may have a sawtooth shape extending along the first direction DR1. According to the inventive concept, the second portion PP1 may be designed to be bent several times, thereby preventing the boundary (e.g., space GS2-1) between the third main pattern SP3_M1 and the second main pattern SP2_M1 disposed inside the second main pattern SP2_M1 from being easily visible. In addition, it may be difficult to distinguish the third main pattern SP3_M1 from the second main pattern SP2_M1. Therefore, the visibility of the input sensing unit ISU_M1 may be improved.

Fig. 14BAn area corresponding to the area XX' of the display unit DPU_H is schematically shown.

[0211] like Fig.14A and Fig. 14B As shown in , the display unit DPU_H includes a plurality of pixels PX. In a plan view, the pixels PX may be arranged around the module hole MH to surround the module hole MH.

The display pad DPD may include a pad D1 connected to the data line DL and a pad D2 connected to the first power terminal VDD. Fig.14A A second power supply terminal VSS connected to the light emitting element ELD is shown. Hereinafter, repeated detailed descriptions for the pixel PX will be omitted.

[0212] The display unit DPU_H is penetrated by the module hole MH. Fig. 14B , two of the signal lines respectively connected to the pixels PX are shown: a first signal line SL1 and a second signal line SL2.

[0213] The first signal line SL1 extends in the first direction DR1. The first signal line SL1 is connected to pixels PX arranged in the same row along the first direction DR1 among the pixels PX. The first signal line SL1 may correspond to the scan line GL. The first signal line SL1 may provide a gate signal for turning on the pixel PX to the corresponding pixel PX.

[0214] A portion of the pixel PX connected to the first signal line SL1 may be disposed at the left side of the module hole MH, and another portion of the pixel PX may be disposed at the right side of the module hole MH. Therefore, even if a portion of the pixel PX relative to the module hole MH is omitted, the pixels PX in the same row connected to the first signal line SL1 may be turned on / off by substantially the same gate signal.

[0215] The second signal line SL2 extends in the second direction DR2.

[0216] A portion of the pixel PX connected to the second signal line SL2 may be disposed above the module hole MH, and another portion of the pixel PX may be disposed below the module hole MH. Therefore, even if a portion of the pixel PX relative to the module hole MH is omitted, the pixels PX in the same column connected to the second signal line SL2 may receive a data signal through the same data line.

[0217] In the display unit DPU_H according to the exemplary embodiment of the inventive concept, the first signal line SL1 may correspond to the scan line GL, and the second signal line SL2 may correspond to the data line DL. Alternatively, the first signal line SL1 and the second signal line SL2 may be one of a power line, an initial voltage line, and an emission control line.

[0219] Refer again Fig. 13B , the housing EDC is disposed below the window panel WP. The housing EDC may be coupled to the window panel WP to define the appearance of the display device DD_H. The housing EDC may include a material having a relatively high rigidity. For example, the housing EDC may include a plurality of frames and / or plates made of at least one of glass, plastic, and metal. The housing EDC provides a predetermined accommodation space. The electronic panel EP_H and the electronic module EM may be accommodated in the accommodation space and thus be protected from external impacts.

[0220] According to the inventive concept, the electronic module EM may be disposed so that a portion of the electronic module EM overlaps the active area AA of the electronic panel EP_H and the transmissive area TA of the window panel WP. Therefore, the surface area of ​​the bezel area BZA may be reduced, thereby improving the aesthetics of the display device DD_H.

[0221] Fig.15A is an exploded perspective view of a display device according to an exemplary embodiment of the inventive concept, Fig. 15B It is shown Fig.15A Hereinafter, reference will be made to Fig.15A and Fig. 15B To describe the inventive concept. Figures 1 to 7 The same components are given the same reference numerals, and their detailed description will be omitted.

[0222] The display device DD_N may include a window panel WP_N, an electronic panel EP_N, an electronic module EM1 and a housing EDC. Fig. 13B Compared with the window panel WP of FIG. 1 , the window panel WP_N may further include a notch portion NTA defined on one side thereof.

[0223] The notch portion NTA may be formed by recessing a portion of the extended side of the window panel WP_N toward the center of the window panel WP_N. Therefore, the front surface FS of the window panel WP_N may include a transmission area TA_N and a frame area BZA_N, each of which has a shape deformed by the notch portion NTA. Each of the transmission area TA_N and the frame area BZA_N may have a shape having one side recessed corresponding to the notch portion NTA.

[0224] A notch portion NTA may be defined in a region of the window panel WP_N overlapping the electronic module EM1. The electronic module EM1 may be a camera, a speaker, or a sensor that senses light or heat. According to the inventive concept, the electronic module EM1 may be exposed to the outside through the notch portion NTA of the window panel WP_N.

[0225] The electronic panel EP_N is disposed between the window panel WP_N and the housing EDC. A notch portion NT may be disposed in the electronic panel EP_N to correspond to the window panel WP_N. The notch portion NT of the electronic panel EP_N may be defined in a position overlapping with the electronic module EM1. According to the inventive concept, the electronic module EM1 may be exposed from the electronic panel EP_N and the window panel WP_N, thereby easily providing an output signal to the outside or easily receiving external information without interfering with the window panel WP_N or the electronic panel EP_N.

[0226] Reference Fig. 15B , the input sensing unit ISU_N may include a predetermined notch portion NT. In this exemplary embodiment, the notch portion NT may be defined by recessing a portion of the upper side of the display unit DPU_N extending in the first direction DR1 in the reverse direction of the second direction DR2.

[0227] Since the notch portion NT is defined, when Figure 6B Input sensing unit ISU (see Figure 6B ), at least a portion of the first electrode TE1_N, the second electrode TE2_N, and the third electrode TE3_N disposed in the sensing area AA2 may have a partially removed shape. For example, a portion of the first electrode TE1_N may have a surface area or length smaller than a surface area or length of a region separated from the notch portion NT due to the notch NT. The first electrode TE1_N separated from the notch portion NT in the second direction DR2 may have a length and a surface area smaller than the length and the surface area of ​​the first electrode separated from the notch portion NT in the first direction DR1.

[0228] In addition, for example, a portion of the second electrode TE2_N may be divided into a left portion and a right portion relative to the notch portion NT. The second connection pattern BP2 that connects two second main patterns SP2 of the second electrode TE2_N that are separated from each other relative to the notch portion NT may extend along the edge of the notch portion NT. Therefore, even if the second electrode TE2_N is divided by the notch portion NT, a portion of the second electrode TE2_N may be electrically connected through the second connection pattern BP2.

[0229] In addition, for example, like the second electrode TE2_N, a portion of the third electrode TE3_N may be divided into a left portion and a right portion with respect to the notch portion NT. Therefore, the third connection pattern BP3 adjacent to the notch portion NT may extend along the edge of the notch portion NT so that two third main patterns SP3 spaced apart from each other in the first direction DR1 with the notch portion NT therebetween are connected to each other. Therefore, even if the third electrode TE3_N is divided by the notch portion NT, a portion of the third electrode TE3_N may be electrically connected through the third connection pattern BP3.

[0230] According to the inventive concept, an input sensing unit ISU_N having various shapes and a display device DD_N including the input sensing unit ISU_N may be provided. In addition, in various shapes of the input sensing unit ISU_N, the third connection pattern BP3 may be designed so that the third connection pattern BP3 does not overlap with the first connection pattern BP1. Therefore, an electronic device may be provided in which the third connection pattern BP3 and the first connection pattern BP1 are prevented from overlapping in a plan view, thereby improving electrical reliability.

[0231] According to the inventive concept, the overlap between signal lines transmitting different electrical signals can be reduced. Therefore, the occurrence of noise caused by electrical interference between signal lines can be reduced, thereby improving the input sensing unit with improved external input sensitivity. In addition, a display device with improved electrical reliability can be provided.

[0232] Although specific exemplary embodiments have been described herein, other embodiments and modifications will be apparent from this description. Therefore, the inventive concept is not limited to such embodiments, but is limited to the broader scope of the claims and various obvious modifications and equivalent arrangements as will be apparent to those of ordinary skill in the art.
