     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     Embodiments may be variously modified and may include various modes. However, embodiments are illustrated in the drawings and are described in detail below. However, it should be understood that the disclosure is not limited to specific forms, but rather cover all modifications, equivalents or alternatives that fall within the spirit and scope of the disclosure. 
     It will be understood that when an element (or a region, layer, portion, or the like) is referred to as being “on”, “connected to”, or “coupled to” another element, it can be directly on or directly connected/coupled to the other element, or a third element may be present therebetween. 
     It will be understood that the terms “connected to” or “coupled to” may include a physical or electrical connection or coupling. 
     The same reference numerals refer to the same elements. In the drawings, the thicknesses, ratios, and dimensions of elements may be exaggerated for clarity of illustration. 
     The terms “first”, “second” and the like may be used for describing various elements, but the elements should not be construed as being limited by the terms. Such terms are only used for distinguishing one element from other elements. For example, a first element could be termed a second element and vice versa without departing from the teachings of the disclosure. 
     The terms of a singular form may include plural forms unless otherwise specified. For example, as used herein, the singular forms, “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. 
     In the specification and the claims, the term “and/or” is intended to include any combination of the terms “and” and “or” for the purpose of its meaning and interpretation. For example, “A and/or B” may be understood to mean “A, B, or A and B.” The terms “and” and “or” may be used in the conjunctive or disjunctive sense and may be understood to be equivalent to “and/or.” 
     In the specification and the claims, the phrase “at least one of” is intended to include the meaning of “at least one selected from the group of” for the purpose of its meaning and interpretation. For example, “at least one of A and B” may be understood to mean “A, B, or A and B.” 
     Furthermore, the terms “under”, “lower side”, “on”, “upper side”, and like are used to describe association relationships among elements illustrated in the drawings. The terms, which are relative concepts, are used on the basis of directions illustrated in the drawings but are not limited thereto. 
     The terms “overlap” or “overlapped” mean that a first object may be above or below or to a side of a second object, and vice versa. Additionally, the term “overlap” may include layer, stack, face or facing, extending over, covering, or partly covering or any other suitable term as would be appreciated and understood by those of ordinary skill in the art. 
     When an element is described as ‘not overlapping’ or ‘to not overlap’ another element, this may include that the elements are spaced apart from each other, offset from each other, or set aside from each other or any other suitable term as would be appreciated and understood by those of ordinary skill in the art. 
     The terms “face” and “facing” mean that a first element may directly or indirectly oppose a second element. In a case in which a third element intervenes between the first and second element, the first and second element may be understood as being indirectly opposed to one another, although still facing each other. 
     It will be further understood that the “comprises,” “comprising,” “includes,” and/or “including,”, “has,” “have,” and/or “having,” and variations thereof when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     “About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ±30%, 20%, 10%, 5% of the stated value. 
     All of the terms used or implied herein (including technical and scientific terms) have the same meanings as understood by those skilled in the art, unless otherwise defined. Terms in common usage such as those defined in commonly used dictionaries should be interpreted to contextually match the lexical meanings in the relevant art, and should not be interpreted in an idealized or overly formal sense unless otherwise defined explicitly. 
     Hereinafter, a display panel according to an embodiment and an electronic apparatus including the same will be described with reference to the accompanying drawings. 
       FIG.  1 A  is a schematic perspective view illustrating an electronic apparatus according to an embodiment.  FIG.  1 B  is an exploded perspective view of an electronic apparatus according to an embodiment. 
     An electronic apparatus ED may be an apparatus which is activated and displays an image according to an electric signal. For example, the electronic apparatus ED may include a large-size apparatus such as a television, an outdoor advertising board, and the like and a small- or medium-size apparatus such as a monitor, a mobile phone, a tablet computer, a navigation device, a game console, and the like within the spirit and the scope of the disclosure. Embodiments of the electronic apparatus ED are illustrative, and the electronic apparatus ED is not limited to any one of the embodiments. In an embodiment, a mobile phone is illustrated as an example of the electronic apparatus ED. 
     Referring to  FIG.  1 A , in a plan view, the electronic apparatus ED may have a rectangular shape having short sides extending in a first direction DR 1  and long sides extending in a second direction DR 2  intersecting the first direction DR 1 . However, an embodiment is not limited thereto, and the electronic apparatus ED may have various shapes such as a circle and a polygon in a plan view. It is to be understood that the shapes disclosed herein may also include shapes substantial to the disclosed shapes. 
     The electronic apparatus ED of an embodiment may be flexible. The term “flexible” represents a bendable characteristic, and may encompass any structure that is completely folded or capable of being bent to a degree of several nanometers. For example, the flexible electronic apparatus ED may include a curved apparatus or foldable apparatus. However, an embodiment is not limited thereto, and the electronic apparatus ED may be rigid. 
     The electronic apparatus ED may display an image IM in a third direction DR 3  on a display surface parallel to each of the first direction DR 1  and the second direction DR 2 . The image IM provided by the electronic apparatus ED may include not only a moving image but also a still image.  FIG.  1 A  illustrates a clock widget and icons as examples of the image IM. 
     The display surface, on which the image IM is displayed, may correspond to a front surface of the electronic apparatus ED, which may correspond to a front surface FS of a window WM. Although  FIG.  1 A  illustrates a planar display surface as an example, an embodiment is not limited thereto, and the display surface of the electronic apparatus ED may include a curved surface bent from at least one side or a side of a plane. 
     A front surface (or upper surface) and a rear surface (or lower surface) of each of members (or units) constituting the electronic apparatus ED may oppose each other in the third direction DR 3 , and a normal direction of each of the front surface and the rear surface may substantially parallel with the third direction DR 3 . A separation distance between the front surface and the rear surface in the third direction DR 3  may correspond to a thickness of a member (or unit). Herein, the term “in a plan view” may be defined as a state viewed in the third direction DR 3 . Herein, the term “in a cross-sectional view” may be defined as a state viewed in the first direction DR 1  or the second direction DR 2 . The directions indicated by the first to third directions DR 1  to DR 3  are relative concept and thus may be changed to other directions. 
     Referring to  FIGS.  1 A and  1 B , the electronic apparatus ED may include the window WM, a display panel DP, and a case EDC. The window WM may be coupled or connected to the case EDC to form an exterior of the electronic apparatus ED and provide an internal space for accommodating components of the electronic apparatus ED. 
     The window WM may be disposed on the display panel DP. The window WM may have a shape corresponding to a shape of the display panel DP. The window WM may cover or overlap an entire front surface of the display panel DP and may protect the display panel DP from an external impact and scratch. 
     The window WM may include an optically clear insulating material. For example, the window WM may include a glass substrate or a polymer substrate. The window WM may have a single-layer or multi-layer structure. The window WM may further include functional layer such as an anti-fingerprint layer, a phase control layer, and a hard coating layer. 
     The front surface FS of the window WM may include a transmission area TA and a bezel area BZA. The transmission area TA of the window WM may be an optically clear area. The window WM may transmit, through the transmission area TA, the image IM provided by the display panel DP, and a user may view the image IM. 
     The bezel area BZA of the window WM may be provided as an area printed with a material having a color. The bezel area BZA of the window WM may prevent a component of the display panel DP overlapping the bezel area BZA from being externally viewed. 
     The bezel area BZA may be adjacent to the transmission area TA. A shape of the transmission area TA may be substantially defined by the bezel area BZA. For example, the bezel area BZA may be disposed outside the transmission area TA and surround the transmission area TA. However, this is illustrative, and the bezel area BZA may be adjacent to only one side or a side of the transmission area TA, or may not be provided. Furthermore, the bezel area BZA may be disposed on a side surface of the electronic apparatus ED rather than the front surface of the electronic apparatus ED. 
     The display panel DP may be disposed between the window WM and the case EDC. The display panel DP may display the image IM according to an electric signal. The display panel DP according to an embodiment may be an emissive display panel, but is not particularly limited thereto. For example, the display panel DP may be an organic light-emitting display panel, an inorganic light-emitting display panel, or a quantum dot light-emitting display panel. An emission layer of the organic light-emitting display panel may include an organic light-emitting material, and an emission layer of the inorganic light-emitting display panel may include an inorganic light-emitting material. An emission layer of the quantum dot light-emitting display panel may include quantum dots, quantum rods, etc. within the spirit and the scope of the disclosure. Hereinafter, the display panel DP will be described as an organic light-emitting display panel. 
     The image IM provided by the electronic apparatus ED may be displayed on a front surface IS of the display panel DP. The front surface IS of the display panel DP may include a display area DA and a non-display area NDA. The display area DA may be an area which is activated and displays the image IM according to an electric signal. According to an embodiment, the display area DA of the display panel DP may overlap the transmission area TA of the window WM. 
     In the disclosure, the wording “area/portion overlaps another area/portion” is not limited to cases in which the area/portions have a same size and/or a same shape. 
     The non-display area NDA may be adjacent to an outer side of the display area DA. For example, the non-display area NDA may surround the display area DA. However, an embodiment is not limited thereto, and the non-display area NDA may be defined as various shapes. 
     The non-display area NDA may be an area in which a driving circuit or driving wiring for driving elements disposed in the display area DA, various signal lines for providing electric signals, and pads are disposed. The non-display area NDA of the display panel DP may overlap the bezel area BZA of the window WM. Components of the display panel DP disposed in the non-display area NDA may be prevented by the bezel area BZA from being externally viewed. 
     The electronic apparatus ED may include a circuit board MB connected to the display panel DP. The circuit board MB may be connected to one end or an end of the display panel DP extending in the first direction DR 1 . The circuit board MB may generate an electric signal provided to the display panel DP. For example, the circuit board MB may include a timing controller, which generates a signal provided to a driver of the display panel DP in response to control signals received externally. 
     At least a portion of the non-display area NDA of the display panel DP may be bent. One portion or a portion of the display panel DP to which the circuit board MB is connected may be bent so that the circuit board MB faces a rear surface of the display panel DP. The circuit board MB may be disposed and assembled so as to overlap the display panel DP in a plan view. However, an embodiment is not limited thereto, and the display panel DP and the circuit board MB may be connected to each other through a flexible circuit board connected to one end or an end of each of the display panel DP and the circuit board MB. 
     The case EDC may be disposed under or below the display panel DP and may accommodate the display panel DP. The case EDC may include a material having a relatively high rigidity, such as glass, plastic, or metal materials. The case EDC may protect the display panel DP by absorbing an externally applied impact or preventing foreign material, moisture, or the like from permeating the display panel DP. 
     The electronic apparatus ED according to an embodiment may further include an input sensing layer, which is disposed on the display panel DP and senses an external input applied externally. The input sensing layer may sense various external inputs such as externally provided force, pressure, temperature, and light. For example, the input sensing layer may sense contact with a user&#39;s body or pen provided from an outside of the electronic apparatus ED or an input (for example, hovering) applied in proximity to the electronic apparatus ED. 
     Furthermore, the electronic apparatus ED may further include an electronic module including various functional modules for operating the display panel DP and a power supply module for supplying required power to the electronic apparatus ED. For example, the electronic apparatus ED may include a camera module as an example of the electronic module and the camera module may be disposed under or below the display panel DP. 
       FIG.  2    is a schematic plan view of a display panel according to an embodiment. The display panel DP may include pixels PX, signal lines electrically connected to the pixels PX, a scan driver SDV, a data driver DDV, and an emission driver EDV. 
     The pixels PX may be disposed in the display area DA. Each of the pixels PX may include a light-emitting element described below, transistors (for example, switching transistor, driving transistor, etc.) connected to the light-emitting element, and a capacitor. Each of the pixels PX may emit light according to an electric signal applied to the pixels PX. 
     Each of the scan driver SDV, the data driver DDV, and the emission driver EDV may be disposed in the non-display area NDA of the display panel DP. Each of the scan driver SDV and the emission driver EDV may be disposed in the non-display area NDA adjacent to long sides of the display panel DP. 
     The data driver DDV may be disposed in the non-display area NDA adjacent to a short side of the display panel DP. The data driver DDV may be provided in a form of an integrated circuit chip defined as a driving chip and may be mounted in the non-display area NDA of the display panel DP. However, an embodiment is not limited thereto, and the data driver DDV may be electrically connected to the display panel DP by being mounted on a separate printed circuit board connected to the display panel DP. 
     The signal lines may include scan lines SL, data lines DL, emission lines EL, first and second control lines CSL 1  and CSL 2 , connection lines DCL, and a power supply line (not shown). Each of the pixels PX may be connected to a corresponding scan line among the scan lines SL and a corresponding data line among the data lines DL. An embodiment is not limited thereto, and more various types of signal lines may be provided to the display panel DP according to a configuration of a pixel driving circuit of the pixels PX. 
       FIG.  2    illustrates one scan line SL among the scan lines SL and one emission line EL among the emission lines EL. The scan line SL may extend in the first direction DR 1  and may be connected to the scan driver SDV. The scan line SL may be provided in plural and may be arranged (or disposed) in the second direction DR 2 . The emission line EL may extend in the first direction DR 1  and may be connected to the emission driver EDV. The emission line EL may be provided in plural and may be arranged in the second direction DR 2 . Although not illustrated, a power supply line may be disposed in the non-display area NDA and may be connected to the pixels PX through a conductive line. The power supply line may provide a reference voltage to the pixels PX. 
     The data lines DL may extend in the second direction DR 2  and may be arranged in the first direction DR 1 . The data lines DL may be divided into a first group G 1 , a second group G 2 , and a third group G 3 . 
     The display panel DP may include connection patterns CP 1 , CP 2 , CP 2n-1 , and CP 2n  disposed in the display area DA. Each of the data lines DL 1 , DL 2 , DL 4   n+m−1 , and DL 4n+m  of the first group G 1  may be connected to a corresponding connection pattern among the connection patterns CP 1 , CP 2 , CP 2   n−1 , and CP 2n . The data lines DL n+1 , DL n+2 , DL 3n+m−1 , and DL 3   n+m  of the second group G 2  may overlap at least one of the connection patterns CP 1 , CP 2 , CP 2n−1 , and CP 2   n  in a plan view. The data lines DL 2n+1  and DL 2n+m  of the third group G 3  may not overlap the connection patterns CP 1 , CP 2 , CP 2n−1  in a plan view. Here, n may be a natural number, and m may be 0 or a natural number. 
     The data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n+m  of the first group G 1  may be arranged adjacent to outer boundaries of the display area DA extending in the second direction DR 2 . Some or a number of data lines DL 1  and DL 2  of the data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n+m  of the first group G 1  may be arranged in the first direction DR 1  from a left boundary of the display area DA to a center portion of the display area DA. For example, some or a number of data lines DL 1  and DL 2  of the data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n+m  of the first group G 1  disposed on a left side may be arrayed in n columns along to the first direction DR 1 .  FIG.  2    illustrates, as an example, the data lines DL 1  and DL 2  of the first group G 1  arranged in a first column and a second column. 
     The data lines DL n+1 , DL n+2 , DL 3   n+m−1 , and DL 3   n+m  of the second group G 2  may be arranged in the first direction DR 1  from a data line disposed closest to the center portion of the display area DA, among the data lines DL 1 , DL 2 , DL 4   n+m−1 , and DL 4   n+m  of the first group G 1 , to the center portion of the display area DA. Some or a number of data lines DL n+1  and DL n+2  of the data lines DL n+1 , DL n+2 , DL 3   n+m−1 , and DL 3   n+m  of the second group G 2  arranged adjacent to the left boundary of the display area DA may be arrayed in the first direction DR 1  from a data line of an nth column of the first group G 1 . Therefore, a data line of the second group G 2  disposed closest to the data lines DL 1  and DL 2  of the first group G 1  disposed on the left side may be a data line of an (n+1)th column. The data lines DL n+1  and DL n+2  of the second group G 2  disposed on the left side may include data lines arranged in an (n+1)th column to (2n)th column along to the first direction DR 1 , and  FIG.  2    illustrates, as an example, the data lines DL n+1  and DL n+2  of the second group G 2  arranged in an (n+1)th column and an (n+2)th column. 
     The data lines DL 2+1  and DL 2n+m  of the third group G 3  may be arranged in an area corresponding to the center portion of the display area DA. The data lines DL 2n+1  and DL 2n+m  of the third group G 3  may be arranged in the first direction DR 1  between the data lines DL n+1 , DL n+2 , DL 3   n+m−1 , and DL 3   n+m  of the second group G 2  arranged on the left side and right side. The data line DL 2+1  disposed on a leftmost side among the data lines DL 2+1  and DL 2n+m  of the third group G 3  may be the data line DL 2n+1  of a (2n+1)th column disposed adjacent to, in the first direction DR 1 , the data line of a (2n)th column included in the second group G 2 . The data lines DL 2n+1  and DL 2n+m  of the third group G 3  may be arranged in m columns along to the first direction DR 1 . 
     Some or a number of data lines DL 3n+m−1  and DL 3   n+m  of the data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n+m  of the second group G 2  disposed on the right side of the display area DA may be arranged in the first direction DR 1  from the data line DL 2n+m  disposed on a rightmost side among the data lines DL 2n+1  and DL 2n+m  of the third group G 3 . A data line disposed closest to the data lines DL 2n+1  and DL 2n+m  of the third group G 3 , among the data lines DL 3n+m−1  and DL 3n+m  of the second group G 2  disposed on the right side, may be a data line of a (2n+m+1)th column. The data lines DL 3n+m−1  and DL 3n+m  of the second group G 2  disposed on the right side may include data lines arranged in a (2n+m+1)th column to a (3n+m)th column along to the first direction DR 1 , and  FIG.  2    illustrates, as an example, the data lines DL 3n+m−1  and DL 3n+m  arranged in a (3n+m−1)th column and a (3n+m)th column among the data lines of the second group G 2  disposed on the right side. 
     The data lines DL 4n+m−1  and DL 4n+m  of the first group G 1  disposed on the right side of the display area DA may be arranged in the first direction DR 1  from a data line of a (3n+m)th column arranged on a rightmost side among the data lines DL 3n+m−1  and DL 3n+m  of the second group G 2  disposed on the right side of the display area DA. A data line disposed closest to the data lines of the second group G 2 , among the data lines DL 4n+m−1  and DL 4   n+m  of the first group G 1  disposed on the right side, may be a data line of a (3n+m+1)th column. The data lines DL 4n+m−1  and DL 4   n+m  of the first group G 1  disposed on the right side may include data lines arranged in a (3n+m+1)th column to a (4n+m)th column along to the first direction DR 1 , and  FIG.  2    illustrates, as an example, the data lines DL 4n+m−1  and DL 4   n+m  arranged in a (4n+m−1)th column and a (4n+m)th column among the data lines of the first group G 1  disposed on the right side. 
     The data lines of the first group G 1  and the data lines of the second group G 2  disposed on the left side of the display area DA may be symmetric with the data lines of the first group G 1  and the data lines of the second group G 2  disposed on the right side of the display area DA with the data lines of the third group G 3  therebetween. In an embodiment, the number of the data lines DL 1 , DL 2 , DL 4   n+m−1 , and DL 4   n+m  of the first group G 1  may be equal to the number of the data lines DL n+1 , DL n+2 , DL 3n+m−1 , and DL 3n+m  of the second group G 2 . Herein, descriptions are provided on the basis of the first group G 1  and the second group G 2  each including data lines arranged in 2n columns. However, the number of data lines included in each group is not limited thereto, and may be designed differently. 
     In an embodiment, the data lines DL 2+1  and DL 2n+m  of the third group G 3  may not be provided. In the case where the data lines DL 2+1  and DL 2n+m  of the third group G 3  is not provided, m may correspond to 0. The data lines DL may be divided into the first group G 1  and the second group G 2 . Therefore, in an embodiment, the data lines of the first group G 1  may be arranged in directions from left and right boundaries of the display area DA to the center portion of the display area DA, and the data lines of the first group G 1  disposed on the left side of the display area DA may be spaced apart from the data lines of the first group G 1  disposed on the right side of the display area DA with the data lines of the second group G 2  therebetween. 
     The connection lines DCL may be disposed in the non-display area NDA and may extend in the second direction DR 2 . The connection lines DCL may be disposed in an area between the data driver DDV and the display area DA. One ends or ends of the connection lines DCL may be connected to the data driver DDV via the non-display area NDA. Each of the connection lines DCL may electrically connect a corresponding data line DL among the data lines DL to the data driver DDV. 
     The data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n+m  of the first group G 1  may be electrically connected to the connection lines DCL via the connection patterns CP 1 , CP 2 , CP 2n−1 , and CP 2n  respectively connected to the data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n + m  of the first group G 1 . Each of the data lines DL n+1 , DL n+2 , DL 3n+m−1 , and DL 3n+m  of the second group G 2  and each of the data lines DL 2+1  and DL 2n+m  of the third group G 3  may be connected to or directly connected to a corresponding connection line DCL among the connection lines DCL. 
     Each of the connection patterns CP 1 , CP 2 , CP 2n−1 , and CP 2n  may electrically connect the data lines DL 1 , DL 2 , DL 4   n+m−1 , and DL 4   n+m  of the first group G 1 , respectively connected thereto, to the connection lines DCL and the data driver DDV. Since the connection patterns CP 1 , CP 2 , CP 2n−1 , and CP 2n  are disposed in the display area DA, a size of a wiring arrangement area required for connecting, to the data driver DDV, the data lines DL 1 , DL 2 , DL 4n+m−1 , and DL 4n+m  of the first group G 1  disposed adjacent to the left and right boundaries of the display area DA may be reduce. For example, a size of a lower portion of the non-display area NDA corresponding to an area between the display area DA and the data driver DDV may be reduced, thus reducing an area of a dead space of the display panel DP. Herein, the term “dead space” may be understood as a space which is devoted to accommodating one or more components that, either singularly or plurally, perform an intended function. 
     The pads PD may be disposed adjacent to a lower end of the non-display area NDA and may be arranged in the first direction DR 1 . The pads PD may be disposed closer to the lower end of the non-display area NDA than the data driver DDV. The pads PD may be portions connected to the above-mentioned circuit board MB of  FIG.  1 B . The pads PD may be electrically connected to the data lines DL, the first control line CSL 1 , and the second control line CSL 2 , respectively. Although not illustrated, the power supply line of the display panel DP may be electrically connected to a corresponding pad PD among the pads PD. 
     The first control line CSL 1  may be connected to the scan driver SDV. The second control line CSL 2  may be connected to the emission driver EDV. 
     The scan driver SDV may generate scan signals in response to a scan control signal. The scan signals may be applied to the pixels PX through the scan lines SL. The data driver DDV may generate data voltages corresponding to image signals in response to a data control signal. The data voltages may be applied to the pixels PX through the data lines DL. The emission driver EDV may generate emission signals in response to an emission control signal. The emission signals may be applied to the pixels PX through the emission lines EL. 
     The pixels PX may be provided with the data voltages in response to the scan signals. The pixels PX may display an image by emitting light of luminance corresponding to the data voltages in response to the emission signals. An emission time of the pixels PX may be controlled by the emission signals. Therefore, the display panel DP may output an image through the display area DA by virtue of the pixels PX. 
       FIG.  3    is an enlarged schematic plan view of a display panel according to an embodiment.  FIG.  3    illustrates, as an example, an enlarged schematic plan view of a lower left area of the display panel DP in which connection patterns CP 1  to CP 6  are disposed. For convenience,  FIG.  3    illustrates, as an example, the data lines DL 1  to DL 6  of the first group G 1  arranged in six columns and the data lines DL 7  to DL 12  of the second group G 2  arranged in six columns. However, the number of the data lines of the first group G 1  and the second group G 2  included in the display panel DP is not limited thereto. 
     Referring to  FIG.  3   , the data lines DL may extend in the second direction DR 2  and may be arranged in the first direction DR 1 . The data lines DL 1  to DL 6  of the first group G 1  may be arranged adjacent to an outer boundary of the display area DA. The data lines DL 1  to DL 6  of the first group G 1  may be arranged in the first direction DR 1  from the outer boundary of the display area DA. The data lines DL 7  to DL 12  of the second group G 2  may be arranged closer to the center portion of the display area DA than the data lines DL 1  to DL 6  of the first group G 1 . 
     Each of the data lines DL 1  to DL 6  of the first group G 1  may be connected to a corresponding connection pattern among the connection patterns CP. Referring to  FIG.  3   , the connection patterns CP may include first to sixth connection patterns CP 1  to CP 6  respectively connected to the data lines DL 1  to DL 6  of first to sixth columns included in the first group G 1 . 
     Each of the data lines DL 7  to DL 12  of the second group G 2  may intersect, in a plan view, at least one of the connection patterns CP. Each of the data lines DL 7  to DL 12  of the second group G 2  may overlap the connection patterns CP in a plan view, and the data lines DL 7  to DL 12  of the second group G 2  may be spaced part from an overlapping connection pattern with an insulating layer therebetween and may be electrically insulated. 
     Each of the connection patterns CP 1  to CP 6  may include a first line extending in the first direction DR 1  and a second line extending in the second direction DR 2 .  FIG.  3    illustrates reference signs of first lines L 1 - 1 , L 1 - 2 , L 1 - 3 , L 1 - 4 , L 1 - 5 , and L 1 - 6  and second lines L 2 - 1 , L 2 - 2 , L 2 - 3 , L 2 - 4 , L 2 - 5 , and L 2 - 6  of the first to sixth connection patterns CP 1  to CP 6 . 
     Each of the first lines L 1 - 1  to L 1 - 6  of the connection patterns CP 1  to CP 6  may extend in the first direction DR 1  and may be disposed so as to overlap the display area DA. One ends or ends of the first lines L 1 - 1  to L 1 - 6  may be connected to the corresponding data lines DL 1  to DL 6  of the first group G 1 , respectively. The first lines L 1 - 1  to L 1 - 6  may be disposed on a layer that is different from that of the data lines DL, and may be respectively connected to the data lines DL 1  to DL 6  of the first group G 1  through a corresponding first contact hole CNT- 1  among first contact holes CNT- 1 . 
     The first lines L 1 - 1  to L 1 - 6  and the data lines DL 1  to DL 6  of the first group G 1  may be connected to each other in the display area DA. Herein, portions at which the first lines L 1 - 1  to L 1 - 6  and the data lines DL 1  to DL 6  of the first group G 1  are connected to each other may be defined as contact portions, wherein the contact portions may be disposed in the display area DA. For example, the contact portions may be disposed in correspondence to the first contact holes CNT- 1  overlapping the display area DA. In the case where the connection patterns CP 1  to CP 6  and the data lines DL 1  to DL 6  of the first group G 1  are connected to each other in the non-display area NDA, each of the connection patterns CP 1  to CP 6  may require additional lines extending from one ends or ends of the first lines L 1 - 1  to L 1 - 6  to the non-display area NDA. Since portions at which the first lines L 1 - 1  to L 1 - 6  are connected to the data lines DL 1  to DL 6  overlap the display area DA, an increase in resistance due to additional lines may be prevented. Furthermore, the connection patterns CP 1  to CP 6  may be connected to the data lines DL 1  to DL 6  without increasing a size of the non-display area NDA, and a process of forming the connection patterns CP 1  to CP 6  may be simplified. 
     The first lines L 1 - 1  to L 1 - 6  of the connection patterns CP 1  to CP 6  may be spaced apart from each other and arranged in the second direction DR 2  in a plan view. The first lines L 1 - 1  to L 1 - 6  may be arranged so that distances between the first lines L 1 - 1  to L 1 - 6  in the second direction DR 2  are equal. 
     The first lines L 1 - 1  to L 1 - 6  of the connection patterns CP 1  to CP 6  may have substantially the same length as each other in the first direction DR 1 . A length of each of the first lines L 1 - 1  to L 1 - 6  may affect resistance of the connection patterns CP 1  to CP 6 . For example, as the length of each of the first lines L 1 - 1  to L 1 - 6  increases, a resistance of the connection patterns CP 1  to CP 6  may increase. Since the first lines L 1 - 1  to L 1 - 6  have the same length as each other, the connection patterns CP 1  to CP 6  may have substantially the same resistance. 
     The first lines L 1 - 1  to L 1 - 6  of the connection patterns CP 1  to CP 6  may have the same line width as each other. Here, the line width of each of the first lines L 1 - 1  to L 1 - 6  may be a width of a line defined in the second direction DR 2 . The line width of each of the first lines L 1 - 1  to L 1 - 6  may affect resistance of the connection patterns CP 1  to CP 6 . Since the connection patterns CP 1  to CP 6  include the first lines L 1 - 1  to L 1 - 6  having the same length and the same line width as each other, the connection patterns CP 1  to CP 6  may have substantially the same resistance. 
     Since the connection patterns CP 1  to CP 6  have the same resistance, a resistance difference between the data lines DL 1  to DL 6  connected to the connection patterns CP 1  to CP 6  may be reduced, and a phenomenon of data signal delay caused by the resistance difference between data lines may be prevented. 
     Each of the first lines L 1 - 1  to L 1 - 6  of the connection patterns CP 1  to CP 6  may intersect and overlap some or a number of the data lines DL in a plan view. For example, referring to  FIG.  3   , the first line L 1 - 1  of the first connection pattern CP 1  may overlap, in a plan view, the data lines DL 2  to DL 6  of second to sixth columns included in the first group G 1  and the data line DL 7  of a seventh column included in the second group G 2 . 
     The numbers of the data lines DL overlapping each of the first lines L 1 - 1  to L 1 - 6  may be the same. For example, the first line L 1 - 1  of the first connection pattern CP 1  may overlap, in a plan view, six data lines DL 2  to DL 7  except for the data line DL 1  of a first column electrically connected to the first line L 1 - 1  of the first connection pattern CP 1 , and the first line L 1 - 2  of the second connection pattern CP 2  may overlap, in a plan view, six data lines DL 3  to DL 8  except for the data line DL 2  of a second column electrically connected to the first line L 1 - 2  of the second connection pattern CP 2 . A capacitance may be formed between the first lines L 1 - 1  to L 1 - 6  and the data lines DL overlapping the first lines L 1 - 1  to L 1 - 6 , and the number of data lines DL overlapping each of the first lines L 1 - 1  to L 1 - 6  may affect a magnitude of the capacitance. 
     Since each of the first lines L 1 - 1  to L 1 - 6  of the connection patterns CP 1  to CP 6  overlaps the same number of data lines DL, a capacitance difference between the connection patterns CP 1  to CP 6  may be reduced. Accordingly, a phenomenon of data signal delay caused by the capacitance difference may be prevented. 
     Each of the second lines L 2 - 1  to L 2 - 6  of the connection patterns CP 1  to CP 6  may extend in the second direction DR 2  and may be disposed so as to overlap the display area DA. One ends or ends of the second lines L 2 - 1  to L 2 - 6  may be respectively connected to the first lines L 1 - 1  to L 1 - 6 . The second lines L 2 - 1  to L 2 - 6  may be disposed on a layer that is different from that of the first lines L 1 - 1  to L 1 - 6 , and may be respectively connected to the first lines L 1 - 1  to L 1 - 6  through a second contact hole CNT- 2 . However, an embodiment is not limited thereto, and the second lines L 2 - 1  to L 2 - 6  may be disposed on a same layer as the first lines L 1 - 1  to L 1 - 6  and may be connected thereto, forming a shape of one piece. 
     The second lines L 2 - 1  to L 2 - 6  of the connection patterns CP 1  to CP 6  may be spaced apart from each other and arranged in the first direction DR 1 . The second lines L 2 - 1  to L 2 - 6  may be arranged so that distances between the second lines L 2 - 1  to L 2 - 6  in the first direction DR 2  are equal. 
     The second lines L 2 - 1  to L 2 - 6  may be disposed on a same layer as the data lines DL. The second lines L 2 - 1  to L 2 - 6  may be formed simultaneously through a same process as that for forming the data lines DL, thus simplifying a process of forming the connection patterns CP 1  to CP 6 . 
     The second lines L 2 - 1  to L 2 - 6  may be spaced apart from the data lines DL in the first direction DR 1 . The second lines L 2 - 1  to L 2 - 6  and the data lines DL may be alternately arranged in the first direction DR 1 . Since the second lines L 2 - 1  to L 2 - 6  are spaced apart from the data lines DL in a plan view, generation of a subsidiary capacitance that may be formed in case that the second lines L 2 - 1  to L 2 - 6  and the data lines DL overlap each other in a plan view may be prevented. 
     The second lines L 2 - 1  to L 2 - 6  of the connection patterns CP 1  to CP 6  may have different lengths as each other in the second direction DR 2 . For example, a length of the second line L 2 - 1  of the first connection pattern CP 1  may be different from a length of the second line L 2 - 2  of the second connection pattern CP 2 . The second line L 2 - 1  of the first connection pattern CP 1  disposed closest to the outer boundary of the display area DA among the first to sixth connection patterns CP 1  to CP 6  may have a shortest length, and the second line L 2 - 6  of the sixth connection pattern CP 6  disposed closer to the center portion of the display area DA among the first to sixth connection patterns CP 1  to CP 6  may have a longest length. 
     Other ends of the second lines L 2 - 1  to L 2 - 6  may be disposed in the non-display area NDA, may be connected to the connection lines DCL extending in the second direction DR 2 , respectively, and may be electrically connected to the data driver DDV (see  FIG.  2   ) through the connection lines DCL. The connection lines DCL may be disposed on a layer that is different from that of the second lines L 2 - 1  to L 2 - 6 , and may be connected to the corresponding second lines L 2 - 1  to L 2 - 6  through a contact hole CH. However, an embodiment is not limited thereto, and the connection lines DCL may be disposed on a same layer as the second lines L 2 - 1  to L 2 - 6  and may be connected thereto, forming a shape of one piece. 
     One ends or ends of the data lines DL 7  to DL 12  of the second group G 2  may be connected to or directly connected to the connection lines DCL, respectively. The connection lines DCL may be disposed on a layer that is different from that of the data lines DL 7  to DL 12  of the second group G 2 , and may be connected to a corresponding data line among the data lines DL 7  to DL 12  of the second group G 2  through the contact hole CH. However, an embodiment is not limited thereto, and the connection lines DCL may be disposed on a same layer as the data lines DL and may be connected thereto, forming a shape of one piece. 
       FIGS.  4 A and  4 B  are schematic cross-sectional views illustrating a display panel according to an embodiment.  FIGS.  4 A and  4 B  correspond to line I-I′ of  FIG.  3   , and illustrate, as an example, cross-sections of one area or an area of the display panel DP in which the first connection pattern CP 1 , the second connection pattern CP 2 , and light-emitting elements OLE are disposed. However, the cross-sections of the display panel DP illustrated in  FIGS.  4 A and  4 B  are examples, and may be changed according to arrangement of connection patterns and light-emitting elements. 
     Referring to  FIGS.  4 A and  4 B , the display panel DP may include a base layer BL, a circuit element layer DP-CL, and a display element layer DP-OL, which are sequentially laminated. 
     The base layer BL may include the display area DA and the non-display area NDA. The base layer BL may provide a base surface on which the circuit element layer DP-CL is disposed. 
     The base layer BL may include a glass substrate, a metal substrate, a polymer substrate, or an organic/inorganic composite material substrate. In an embodiment, the base layer BL may include a synthetic resin layer. For example, the synthetic resin layer of the base layer BL may include at least one of acrylate-based resin, methacrylate-based resin, polyisoprene-based resin, vinyl-based resin, epoxy-based resin, urethane-based resin, cellulose-based resin, siloxane-based resin, polyamide-based resin, perylene-based resin, or polyimide-based resin. However, a material of the base layer BL is not limited to the above example. 
     The circuit element layer DP-CL may be disposed on the base layer BL. The circuit element layer DP-CL may include at least one insulating layer, conductive pattern, and semiconductor pattern. While manufacturing the display panel DP, an insulating layer, a semiconductor layer, and a conductive layer may be formed on the base layer BL by coating, deposition, or the like within the spirit and the scope of the disclosure. Thereafter, the insulating layer, the semiconductor layer, and the conductive layer may be selectively patterned through photolithography. Through this process, the semiconductor pattern, conductive pattern, and signal lines included in the circuit element layer DP-CL may be formed. The cross-sections of the circuit element layer DP-CL illustrated in  FIGS.  4 A and  4 B  are examples, and a laminate structure of the circuit element layer DP-CL may be variously changed according to a process procedure, a process method, or configuration of elements included in pixels. 
     Each pixel may have an equivalent circuit including transistors, at least one capacitor and a light-emitting element, and the equivalent circuit of the pixel may be modified into various forms. The semiconductor pattern may be arranged over pixels according to the equivalent circuit and a prescribed rule.  FIGS.  4 A and  4 B  illustrate, as an example, one transistor TR and the light-emitting element OLE. 
     The circuit element layer DP-CL may include the transistor TR, connection electrodes CNE 1  and CNE 2 , and insulating layers  10  to  50 . The circuit element layer DP-CL may include the above-mentioned signal lines, and  FIGS.  4 A and  4 B  illustrate, as an example, the data lines DL 1  to DL 7 , the first connection pattern CP 1 , the second connection pattern CP 2 , and the connection line DCL, included in the circuit element layer DP-CL. 
     In an embodiment, the insulating layers  10  to  50  may include first to fifth insulating layers  10  to  50 . The first to fifth insulating layers  10  to  50  may be disposed on the base layer BL. Each of the first to fifth insulating layers  10  to  50  may include an organic layer or an inorganic layer. The inorganic layer may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, or hafnium oxide, but is not limited thereto. The organic layer may include a phenol-based polymer, acryl-based polymer, imide-based polymer, aryl ether-based polymer, amide-based polymer, fluorine-based polymer, p-xylene-based polymer, vinyl alcohol-based polymer, and combinations thereof, but is not limited thereto. 
     The first insulating layer  10  may be disposed on the base layer BL. The first insulating layer  10  may include an inorganic layer, and may be provided as a buffer layer and/or barrier layer on the base layer BL. The buffer layer may enhance a bonding strength between the base layer BL and the semiconductor pattern or conductive pattern. The barrier layer may prevent foreign material from flowing from the outside to the semiconductor pattern and the conductive pattern. 
     The semiconductor pattern of the transistor TR may be disposed on the first insulating layer  10 . The semiconductor pattern may include polysilicon. However, an embodiment is not limited thereto, and the semiconductor pattern may include amorphous silicon, crystalline oxide, or non-crystalline oxide. 
     A source area Sa, a drain area Da, and a channel area Aa of the transistor TR may be formed from the semiconductor pattern. The semiconductor pattern may be divided into areas according to conductivity. For example, the semiconductor pattern may have different electric properties according to whether the semiconductor pattern is doped or whether reduction of metal oxide occurs. An area having high conductivity in the semiconductor pattern may serve as an electrode or a signal line, which may correspond to the source area Sa and the drain area Da of the transistor TR. An area having relatively low conductivity without being doped or reduced may correspond to the channel area Aa (or active area) of the transistor TR. 
     The second insulating layer  20  may be disposed on the first insulating layer  10 , covering or overlapping the semiconductor pattern of the transistor TR. A gate electrode Ga may be disposed on the second insulating layer  20 . The gate electrode Ga may overlap the channel area Aa. In a schematic cross-sectional view, the gate electrode Ga may be spaced apart from the semiconductor pattern of the transistor TR with the second insulating layer  20  therebetween. In an embodiment, the gate electrode Ga may function as a mask during a process of doping the semiconductor pattern. 
     The third insulating layer  30  may be disposed on the second insulating layer  20  so as to cover or overlap the gate electrode Ga. The first connection electrode CNE 1  may be disposed on the third insulating layer  30 . The first connection electrode CNE 1  may be connected to the source area Sa of the transistor TR through a channel hole penetrating the second and third insulating layers  20  and  30 . 
     The fourth insulating layer  40  may be disposed on the third insulating layer  30  so as to cover or overlap the first connection electrode CNE 1 . The second connection electrode CNE 2  may be disposed on the fourth insulating layer  40 . The second connection electrode CNE 2  may be connected to the first connection electrode CNE 1  through a channel hole penetrating the fourth insulating layer  40 . 
     The fifth insulating layer  50  may be disposed on the fourth insulating layer  40  so as to cover or overlap the second connection electrode CNE 2 . The fifth insulating layer  50  may have defined therein a channel hole exposing a portion of the second connection electrode CNE 2 , and the second connection electrode CNE 2  may be connected to a pixel electrode AE of the light-emitting element OLE through this channel hole. Therefore, the first connection electrode CNE 1  and the second connection electrode CNE 2  may electrically connect the source area Sa of the transistor TR to the pixel electrode AE. 
     Referring to  FIG.  4 A , the first connection pattern CP 1  and the second connection pattern CP 2  may be disposed within the display area DA.  FIG.  4 A  illustrates, as an example, the first connection pattern CP 1  overlapping a non-emission area NPXA of the display area DA and the second connection pattern CP 2  partially overlapping an emission area PXA of the display area DA. However, arrangement of the pixel electrode AE included in the display panel DP may be variously changed according to embodiments, and at least portion of the connection patterns CP (see  FIG.  3   ) may overlap the emission area PXA. As long as the connection patterns CP (see  FIG.  3   ) are connected to corresponding data lines DL in the display area DA, an embodiment is not limited thereto. 
     In an embodiment, the first line L 1 - 1  of the first connection pattern CP 1  may be disposed on the third insulating layer  30 . The first line L 1 - 2  of the second connection pattern CP 2  may be disposed on the third insulating layer  30  that is the same layer as that on which the first line L 1 - 1  of the first connection pattern CP 1  is disposed. The first line L 1 - 1  of the first connection pattern CP 1  and the first line L 1 - 2  of the second connection pattern CP 2  may be disposed on a same layer as that of the first connection electrode CNE 1  and may be formed through a same process. The fourth insulating layer  40  may be disposed on the first lines L 1 - 1  and L 1 - 2  and may have formed therein the first and second contact holes CNT- 1  and CNT- 2  exposing portions of the first lines L 1 - 1  and L 1 - 2 \. 
     The second line L 2 - 1  of the first connection pattern CP 1  may be disposed on the fourth insulating layer  40 . The second line L 2 - 1  may be disposed on a same layer as that of the second connection electrode CNE 2 , and may be formed through a same process. Although not illustrated in  FIG.  4 A , the second line L 2 - 2  (see  FIG.  3   ) of the second connection pattern CP 2  may also be disposed on the fourth insulating layer  40  that is a same layer as that on which the second line L 2 - 1  of the first connection pattern CP 1  is disposed. The first and second connection patterns CP 1  and CP 2  may be formed during a process of forming driving elements included in the circuit element layer DP-CL without adding a process procedure or a conductive layer. In this manner, a forming process of the first and second connection patterns CP 1  and CP 2  may be simplified. 
     The data lines DL may be disposed on the fourth insulating layer  40 . The data lines DL may be disposed on a same layer as that of the second line L 2 - 1  of the first connection pattern CP 1 . The data line DL may be arranged in one direction or a direction on the fourth insulating layer  40 . 
     The data line DL 1  of a first column among the data lines DL may be connected to the first connection pattern CP 1 . The data line DL 1  of a first column may be connected to the first line L 1 - 1  of the first connection pattern CP 1  through the first contact hole CNT- 1 . The second line L 2 - 1  of the first connection pattern CP 1  may be connected to the first line L 1 - 1  through the second contact hole CNT- 2 . 
     The data line DL 2  of a second column among the data lines DL may be connected to the second connection pattern CP 2 . The data line DL 2  of a second column may be connected to the first line L 1 - 2  of the second connection pattern CP 2  through the first contact hole CNT- 1 . 
     The first line L 1 - 1  of the first connection pattern CP 1  may overlap portion of the data lines DL. Referring to  FIG.  4 A , the first line L 1 - 1  of the first connection pattern CP 1  may overlap the data line DL 2  of a second column to the data line DL 7  of a seventh column. For example, the first line L 1 - 1  of the first connection pattern CP 1  may overlap the data lines DL 2  to DL 7  of six columns except for the data line DL 1  of a first column connected to the first line L 1 - 1  of the first connection pattern CP 1 , and the number of data lines overlapping the first line L 1 - 1  may affect capacitance formed due to a connection pattern. 
     Since the first lines of connection patterns according to an embodiment are formed so that the numbers of data lines overlapping each of the first lines are equal, the resistances and capacitances of the connection patterns may be substantially the same. In this manner, differences of resistance and capacitance between data lines connected to connection patterns may be minimized. Accordingly, degradation of display quality due to differences of resistance and capacitance may be prevented. 
     The first line L 1 - 1  of the first connection pattern CP 1  may be disposed on an upper layer than the data lines DL, without being limited to the embodiment illustrated in  FIG.  4 A . For example, in an embodiment, the data lines DL and the second line L 2 - 1  of the first connection pattern CP 1  may be disposed on the third insulating layer  30 , and the first line L 1 - 1  of the first connection pattern CP 1  may be disposed on the fourth insulating layer  40 . 
     The connection line DCL disposed in the non-display area NDA may be disposed on the second insulating layer  20 . The connection line DCL may be disposed on a same layer as that of the gate electrode Ga. The connection line DCL may be connected to the second line L 2 - 1  of the first connection pattern CP 1  through the contact hole CH penetrating the third and fourth insulating layers  30  and  40 . The connection line DCL may receive a data signal by being connected to the data driver DDV (see  FIG.  2   ), and the data signal may be transferred to the data line DL 1  of a first column through the first connection pattern CP 1 . However, an embodiment is not limited thereto, and the connection line DCL may be disposed on a same layer as that of the second line L 2 - 1  and connected thereto so as to be integral and connected to each other. 
     The embodiment of the display panel DP illustrated in  FIG.  4 B  may include substantially the same configuration as the embodiment of  FIG.  4 A , and may be different from the embodiment of  FIG.  4 A  with respect to a partial configuration of the first connection pattern CP 1 . Referring to  FIG.  4 B , the first line L 1 - 1  and the second line L 2 - 1  of the first connection pattern CP 1  may be formed on a same layer. In an embodiment, the first line L 1 - 1  and the second line L 2 - 1  of the first connection pattern CP 1  may be disposed on the third insulating layer  30 , and the first line L 1 - 1  and the second line L 2 - 1  may be integral and connected to each other. 
     Although the connection patterns have been described on the basis of the first connection pattern CP 1  illustrated in  FIGS.  4 A and  4 B , the above descriptions may also be applied to other connection patterns. 
     Referring to  FIGS.  4 A and  4 B , the display element layer DP-OL may be disposed on the circuit element layer DP-CL. The display element layer DP-OL may include the light-emitting elements OLE, a pixel defining layer PDL, and an encapsulation layer TFL. 
     The display area DA may include the emission area PXA corresponding to the light-emitting element OLE and the non-emission area NPXA surrounding the emission area PXA. The light-emitting element OLE may be provided in plural, and the display area DA may include the emission areas PXA corresponding to the light-emitting elements OLE. The non-emission area NPXA may surround the emission areas PXA. 
     The light-emitting element OLE may include the pixel electrode AE, an emission layer EML, and a common electrode CE. The pixel electrode AE may be disposed on the fifth insulating layer  50 . The pixel defining layer PDL may be disposed on the pixel electrode AE and the fifth insulating layer  50 , and may have defined therein an opening OP exposing a portion of the pixel electrode AE. The portion of the pixel electrode AE exposed by the opening OP of the pixel defining layer PDL may correspond to the emission area PXA. 
     The pixel defining layer PDL may include an organic material. The pixel defining layer PDL of an embodiment may have a color. For example, the pixel defining layer PDL may include a base resin and a black pigment and/or black dye mixed with the base resin. However, an embodiment of the pixel defining layer PDL is not limited thereto. 
     The emission layer EML may be disposed on the pixel electrode AE. The emission layer EML may be disposed in an area corresponding to the opening OP of the pixel defining layer PDL. The emission layer EML may include an organic light-emitting material, an inorganic light-emitting material, quantum dots, or quantum rods. The emission layer EML may be separately formed in each pixel. However, an embodiment is not limited thereto, and the emission layer EML may be commonly formed in pixels, and may generate a first light that is a source light. 
     In an embodiment, the light-emitting element OLE may be a light-emitting element having a tandem structure including emission layers. The emission layers may be laminated on the pixel electrode AE in a thickness direction. The emission layers may generate light of a same color, or some or a number of the emission layers may generate light of a different color from that of the other emission layers. The light-emitting element having the tandem structure may further include functional layers such as a hole control layer, an electron control layer, and a charge generation layer, disposed between the emission layers. 
     The common electrode CE may be disposed on the emission layer EML. The common electrode CE may be commonly disposed in pixels. The common electrode CE may overlap the emission area PXA and the non-emission area NPXA. A common voltage may be provided to the common electrode CE. 
     The light-emitting element OLE may further include emission functional layers disposed between the pixel electrode AE and the common electrode CE. For example, the light-emitting element OLE may include a hole transport layer or hole injection layer disposed between the pixel electrode AE and the emission layer EML, and may include an electron transport layer or electron injection layer disposed between the emission layer EML and the common electrode CE. 
     A first voltage may be applied to the pixel electrode AE through the transistor TR, and a common voltage may be applied to the common electrode CE. Holes and electrons injected to the emission layer EML may combine with each other to form an exciton, and the light-emitting element OLE may output light through the emission area PXA as the exciton transitions to a ground state. 
     The encapsulation layer TFL may be disposed on the light-emitting element OLE and the pixel defining layer PDL so as to seal the light-emitting element OLE. In an embodiment, the encapsulation layer TFL may include first and second inorganic layers IO 1  and IO 2  and an organic layer OL disposed between the first and second inorganic layers IO 1  and IO 2 . However, a laminate structure of the encapsulation layer TFL is not limited thereto. 
     The first and second inorganic layers IO 1  and IO 2  may protect the light-emitting element OLE from moisture and/or oxygen. For example, the first and second inorganic layers IO 1  and IO 2  may include at least one of aluminum oxide, titanium oxide, silicon oxide, silicon nitride, silicon oxynitride, zirconium oxide, or hafnium oxide, but is not limited thereto. 
     The organic layer OL may protect the light-emitting element OLE from foreign material such as dust particles. For example, the organic layer OL may include an acryl-based resin, but is not limited thereto. 
       FIG.  5    is an enlarged schematic plan view of a display panel according to an embodiment.  FIGS.  6 A and  6 B  are schematic plan views of load blocks according to an embodiment. The display panel DP of  FIG.  5    may include substantially the same configuration as the display panel DP of  FIG.  3   , and may partially differ in configuration from the display panel DP of  FIG.  3   . The following descriptions are focused on differences. 
     The display panel DP of an embodiment may include a load block connected to at least one of the data lines DL 7  to DL 12  of the second group G 2 .  FIG.  5    illustrates, as an example, first to sixth load blocks LB 1  to LB 6  respectively connected to the data lines DL 7  to DL 12  of the second group G 2 . The load blocks LB 1  to LB 6  may have a load magnitude. However, an embodiment is not limited thereto, and a portion of the load blocks LB 1  to LB 6  may have a load magnitude of 0. A portion of the first to sixth load blocks LB 1  to LB 6  respectively connected to the data lines DL 7  to DL 12  of the second group G 2  may be omitted. An omitted load block may correspond to a load block having a load magnitude of 0. 
     The load blocks LB 1  to LB 6  may include configurations for controlling resistance and/or capacitance of the data lines DL 7  to DL 12  of the second group G 2 . For example, each of the load blocks LB 1  to LB 6  may be provided as a capacitor connected to a data line, or may be provided as a resistance compensation pattern connected to a data line and having a form of a line. The load blocks LB 1  to LB 6  all may be provided as a capacitor or all may be provided as a resistance compensation pattern, but an embodiment is not limited thereto, and a portion of the load blocks LB 1  to LB 6  may be provided as a capacitor and another portion may be provided as a resistance compensation pattern. 
     Referring to  FIG.  5   , the data line DL 7  of a seventh column among the data lines DL 7  to DL 12  of the second group G 2  may be disposed closest to the data lines DL 1  to DL 6  of the first group G 1  in the first direction DR 1 . The data lines DL 7  to DL 12  of seventh to 12th columns included in the second group G 2  may be arranged in the first direction DR 1 . Therefore, the data line DL 12  of a 12th column among the data lines DL 7  to DL 12  of the second group G 2  may be arranged farthest from the data lines DL 1  to DL 6  of the first group G 1 . 
     At least two load blocks among the first to sixth load blocks LB 1  to LB 6  may have different load magnitudes as each other. For example, at least a portion of the first to sixth load blocks LB 1  to LB 6  may differ in a resistance and/or capacitance. For example, the data lines DL 7  to DL 12  of the second group G 2  may be arranged spaced apart farther from the data lines DL 1  to DL 6  of the first group G 1  in a direction from the data line DL 7  of a seventh column to the data line DL 12  of a 12th column, and resistance and/or capacitance of the first to sixth load blocks LB 1  to LB 6  connected to corresponding data lines among the data lines DL 7  to DL 12  of the second group G 2  may sequentially reduce. The resistance and/or capacitance of the first load block LB 1 , among the first to sixth load blocks LB 1  to LB 6 , connected to the data line DL 7  of a seventh column disposed closest to the data lines DL 1  to DL 6  of the first group G 1  may be largest, and the resistance and/or capacitance of the sixth load block LB 6 , among the first to sixth load blocks LB 1  to LB 6 , connected to the data line DL 12  of a 12th column disposed spaced apart farthest from the data lines DL 1  to DL 6  of the first group G 1  may be smallest. 
     However, an embodiment is not limited thereto, and portions of the first to sixth load blocks LB 1  to LB 6  may have the same resistance and/or capacitance. In detail, load blocks respectively connected to data lines that are adjacent to each other in the first direction DR 1  among the data lines DL 7  to DL 12  of the second group G 2  may have the same resistance and/or capacitance. 
     The first to sixth load blocks LB 1  to LB 6  may be connected to the data lines of the second group G 2  so as to gradually reduce a resistance and/or capacitance difference with the data lines of the first group G 1  connected to the connection patterns CP. For example, the resistance and/or capacitance of the first load block LB 1  may be substantially the same as or similar to the resistance and/or capacitance of the sixth connection pattern CP 6  connected to the data line DL 6  of a sixth column among the data lines of the first group G 1  adjacent to the data line DL 7  of a seventh column. 
     Load values of the first to sixth load blocks LB 1  to LB 6  may gradually reduce so as not to increase a resistance and/or capacitance difference between the data lines of the second group G 2 . For example, the resistance and/or capacitance of the second load block LB 2  connected to the data line DL 8  of an eighth column adjacent to the data line DL 7  of a seventh column among the data lines of the second group G 2  may be smaller than or substantially the same as the resistance and/or capacitance of the first load block LB 1 . The resistance and/or capacitance of the sixth load block LB 6  connected to the data line DL 12  of a 12th column may be smallest among the resistances and/or capacitances of the first to sixth load blocks LB 1  to LB 6 . For example, the resistance value or capacitance value of the sixth load block LB 6  may be substantially 0 or close to 0. 
       FIG.  6 A  is a schematic plan view illustrating the first and second load blocks LB 1  and LB 2  provided in a form of a resistance compensation pattern. Each of the first and second load blocks LB 1  and LB 2  provided as a resistance compensation pattern may be connected to a corresponding data line and may have a form of a line. Referring to  FIG.  6 A , the first and second load blocks LB 1  and LB 2  of an embodiment, provided as a resistance compensation pattern, may have a curved form shaped like “U” in a plan view. 
     The first load block LB 1  having a structure of a resistance compensation pattern may be referred to as a first resistance compensation pattern, and the second load block LB 2  having a structure of a resistance compensation pattern may be referred to as a second resistance compensation pattern. The first resistance compensation pattern may be connected to the data line DL 7  of a seventh column, and the second resistance compensation pattern may be connected to the data line DL 8  of an eighth column. 
     The load magnitude of the first load block LB 1  may be larger than the load magnitude of the second load block LB 2 . For example, the magnitude of resistance of the first load block LB 1  provided as a resistance compensation pattern (for example, a resistance of the first resistance compensation pattern) may be larger than the magnitude of resistance of the second load block LB 2  (for example, a resistance of the second resistance compensation pattern). A length of the resistance compensation pattern may affect a resistance of the resistance compensation pattern. Therefore, the length of the first resistance compensation pattern may be larger than the length of the second resistance compensation pattern. 
     The load blocks LB 1  to LB 6  provided in a form of a resistance compensation pattern may be connected to corresponding data lines, respectively, in the display area DA. However, an embodiment is not limited thereto, and the load blocks LB 1  to LB 6  provided in a form of a resistance compensation pattern may be connected to corresponding data lines, respectively, in the non-display area NDA. An embodiment of a resistance compensation pattern disposed in the display area DA will be described in detail with reference to  FIGS.  7 A,  7 B, and  8   . 
       FIG.  6 B  is a schematic plan view illustrating the first and second load blocks LB 1  and LB 2  provided in a form of a capacitor. Referring to  FIG.  6 B , each of the first and second load blocks LB 1  and LB 2  having a form of a capacitor may be connected to a corresponding data line, and may include electrodes having a planar area size. Each of the first load block LB 1  and the second load block LB 2  may include first electrode E 1 - 1  and E 1 - 2  and second electrode E 2 - 1  and E 2 - 2  overlapping each other in a plan view. 
     The load magnitude of the first load block LB 1  may be larger than the load magnitude of the second load block LB 2 . Therefore, a capacitance of the first load block LB 1  provided as a capacitor (for example, a capacitance of a first capacitor) may be larger than a capacitance of the second load block LB 2  provided as a capacitor (for example, a capacitance of a second capacitor). The planar area size of the electrodes may affect the capacitance of the capacitors. The planar area sizes of the first and second electrodes E 1 - 1  and E 2 - 1  of the first load block LB 1  may be larger than the planar area sizes of the first and second electrodes E 1 - 2  and E 2 - 2  of the second load block LB 2 . 
     The load blocks LB 1  to LB 6  provided in a form of a capacitor may be connected to corresponding data lines, respectively, in the display area DA. However, an embodiment is not limited thereto, and the load blocks LB 1  to LB 6  provided in a form of a capacitor may be connected to corresponding data lines, respectively in the non-display area NDA. An embodiment of a capacitor disposed in the non-display area NDA will be described in detail with reference to  FIG.  9   . 
     The first to sixth load blocks LB 1  to LB 6  may reduce a resistance and/or capacitance difference between the data lines DL 1  to DL 6  of the first group G 1  and the data lines DL 7  to DL 12  of the second group G 2 . Furthermore, the load blocks LB 1  to LB 6  may reduce a resistance and/or capacitance difference between the data lines DL 7  to DL 12  of the second group G 2 . In case that the resistance and/or capacitance of data lines sharply changes between data lines, degradation of display quality such as a stain may occur in the display area DA. The first to sixth load blocks LB 1  to LB 6  may prevent the degradation of display quality by reducing the resistance and/or capacitance difference between the data lines DL. 
     Although descriptions are provided on the basis of 12 data lines DL for convenience, the number of data lines DL actually included in the display panel DP may be larger. 
       FIGS.  7 A and  7 B  are enlarged schematic plan views of a display panel according to an embodiment.  FIGS.  7 A and  7 B  illustrate embodiments of load blocks provided in a form of a resistance compensation pattern. The following descriptions are focused on resistance compensation patterns RC 1  and RC 2 . 
     A portion of the above-mentioned first to sixth load blocks LB 1  to LB 6  may be omitted, and  FIGS.  7 A and  7 B  illustrate, as an example, the first load block LB 1  (see  FIG.  5   ) provided as the first resistance compensation pattern RC 1  and a second load block LB 2  (see  FIG.  5   ) provided as the second resistance compensation pattern RC 2 . However, an embodiment is not limited thereto. 
     The first and second resistance compensation patterns RC 1  and RC 2  may be disposed in the display area DA. The first resistance compensation pattern RC 1  may be connected to the data line DL 7  of a seventh column, and the second resistance compensation pattern RC 2  may be connected to the data line DL 8  of an eighth column. 
     Each of the first and second resistance compensation patterns RC 1  and RC 2  may include first portion P 1 - 1  and P 1 - 2  and second portion P 2 - 1  and P 2 - 2  extending in the first direction DR 1  and third portion P 3 - 1  and P 3 - 2  extending in the second direction DR 2 . 
     In case that the resistance compensation patterns is described with the basis of the first resistance compensation pattern RC 1 , the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be spaced apart from each other in the second direction DR 2  in a plan view. The third portion P 3 - 1  of the first resistance compensation pattern RC 1  may be connected to one end or an end of the first portion P 1 - 1  and one end or an end of the second portion P 2 - 1  so as to connect the first portion P 1 - 1  and the second portion P 2 - 1 . 
     The first portion P 1 - 1  and the second portion P 2 - 1  may be formed on a same layer. The first portion P 1 - 1  and the second portion P 2 - 1  may be formed on a same layer as that of the first lines L 1 - 1  to L 1 - 6  of the connection patterns CP. The first portion P 1 - 1  and the second portion P 2 - 1  may be simultaneously formed through a same process as that of the first lines L 1 - 1  to L 1 - 6  of the connection patterns CP. 
     The third portion P 3 - 1  may be formed on a layer different from that of the first portion P 1 - 1  and the second portion P 2 - 1 . The third portion P 3 - 1  may be formed on a same layer as that of the second lines L 2 - 1  to L 2 - 6  of the connection patterns CP. The third portion P 3 - 1  may be simultaneously formed through a same process as that of the second lines L 2 - 1  to L 2 - 6  of the connection pattern CP. The third portion P 3 - 1  may be disposed on a same layer as the data lines DL. 
     The resistance compensation patterns RC 1  and RC 2  may be simultaneously formed with the connection patterns CP during a forming process of the connection patterns CP. Therefore, since the resistance compensation patterns RC 1  and RC 2  may be formed together with the connection patterns CP during the forming process of the connection patterns CP without adding a process procedure or a conductive layer, a forming process of the resistance compensation patterns RC 1  and RC 2  may be simplified. 
     One end or an end of the first portion P 1 - 1  of the first resistance compensation pattern RC 1  may be connected to the data line DL 7  of a seventh column through a third contact hole CNT- 3 . The other end or another end of the first portion P 1 - 1  may be connected to one end or an end of the third portion P 3 - 1  through a fourth contact hole CNT- 4 . One end or an end of the second portion P 2 - 1  may be connected to the other end or another end of the third portion P 3 - 1  through a fifth contact hole CNT- 5 , and the other end or another end of the second portion P 2 - 1  may be connected to the data line DL 7  of a seventh column through a sixth contact hole CNT- 6 . 
     A portion of the data line DL 7  of a seventh column connected to the first portion P 1 - 1  and a portion of the data line DL 7  of a seventh column connected to the second portion P 2 - 1  may be spaced apart from each other and may be electrically connected to each other through the first resistance compensation pattern RC 1 . Portions of the data line D 7  of a seventh column respectively connected to the first portion P 1 - 1  and the second portion P 2 - 1  may be electrically connected to each other through the first resistance compensation pattern RC 1  and may be defined as one data line for receiving the same signal. 
     Although the resistance compensation patterns have been described on the basis of the first resistance compensation pattern RC 1  and the data line DL 7  of a seventh column, the relevant descriptions may also be applied to the second resistance compensation pattern RC 2  and the data line DL 8  of an eighth column connected thereto. 
     The resistance of the first resistance compensation pattern RC 1  may be different from the resistance of the second resistance compensation pattern RC 2 . The resistance of the first resistance compensation pattern RC 1  connected to the data line DL 7  of a seventh column disposed closer to the data lines DL 1  to DL 6  of the first group G 1  may be larger than the resistance of the second resistance compensation pattern RC 2 . 
     Lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may affect the resistance of the first resistance compensation pattern RC 1 . A sum of the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be larger than a sum of lengths of the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2 . 
     The first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1 , in a plan view, may be electrically insulated and may overlap a portion of the data lines DL. The number of data lines DL overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may affect the capacitance of the first resistance compensation pattern RC 1 . The number of data lines DL overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be larger than the number of data lines DL overlapping the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2 . For example, referring to  FIG.  7 A , each of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may overlap the data lines DL 8  and DL 9  of eighth and ninth columns except for the data line DL 7  of a seventh column to which the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  are electrically connected. Each of the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2  may overlap the data line DL 9  of a ninth column except for the data line DL 8  of an eighth column to which the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2  are electrically connected. 
     Line widths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be substantially the same as line widths of the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2 . Here, the line widths may correspond to the widths of lines defined in the second direction DR 2 . The resistance of the first resistance compensation pattern RC 1  and the resistance of the second resistance compensation pattern RC 2  may be controlled by adjusting the lengths of the first portions P 1 - 1  and P 1 - 2  and the second portions P 2 - 1  and P 2 - 2  in the first direction DR 1 . However, an embodiment is not limited thereto, and the resistance of the first resistance compensation pattern RC 1  and the resistance of the second resistance compensation pattern RC 2  may also be controlled by adjusting the line widths of the first portions P 1 - 1  and P 1 - 2  and the second portions P 2 - 1  and P 2 - 2  in the second direction DR 2 . 
     A length of the third portion P 3 - 1  of the first resistance compensation pattern RC 1  may be substantially the same as a length of the third portion P 3 - 2  of the second resistance compensation pattern RC 2 . However, an embodiment is not limited thereto. 
     By adjusting the resistances and/or capacitances of the first resistance compensation pattern RC 1  and the second resistance compensation pattern RC 2 , a resistance and/or capacitance difference between the data line connected to the first resistance compensation pattern RC 1  and the data line connected to the second resistance compensation pattern RC 2  may be reduced. 
     The sixth connection pattern CP 6  may be disposed closest to the first resistance compensation pattern RC 1  in a plan view among the connection patterns CP. The resistance of the first resistance compensation pattern RC 1  may be substantially the same as or similar to the resistance of the sixth connection pattern CP 6 . Furthermore, the capacitance of the first resistance compensation pattern RC 1  may be substantially the same as or similar to the capacitance of the sixth connection pattern CP 6 . 
     Referring to  FIG.  7 A , in an embodiment, the resistance and capacitance of the first resistance compensation pattern RC 1  may be designed to be smaller than the resistance and capacitance of the sixth connection pattern CP 6 . However, an embodiment is not limited thereto, and, referring to  FIG.  7 B , the resistance and capacitance of the first resistance compensation pattern RC 1  may be designed to be larger than the resistance and capacitance of the sixth connection pattern CP 6  in an embodiment. The disclosure is not limited to any one embodiment unless resistance and capacitance differences significantly increase between the first resistance compensation pattern RC 1  and the sixth connection pattern CP 6 . 
     Referring to  FIG.  7 A , the sum of the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be smaller than a length of the first line L 1 - 6  of the sixth connection pattern CP 6 . Accordingly, the number of data lines DL overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be smaller than the number of data lines DL overlapping the first line L 1 - 6  of the sixth connection pattern CP 6 . For example, referring to  FIG.  7 A , the first line L 1 - 6  of the sixth connection pattern CP 6  may overlap six data lines (the data lines DL 7  to DL 12  of seventh to 12th columns in  FIG.  7 A ) except for the data line DL 6  of a sixth column to which the first line L 1 - 6  of the sixth connection pattern CP 6  is electrically connected. Each of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may overlap, in a plan view, two data lines (the data lines DL 8  and LD 9  of an eighth and ninth columns in  FIG.  7 A ) except for the data line DL 7  of a seventh column to which the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  are electrically connected. For example, the total number of data lines DL overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be four, which may be smaller than the number of data lines DL overlapping the first line L 1 - 6  of the sixth connection pattern CP 6 . 
     The resistance and/or capacitance of the second resistance compensation pattern RC 2  may be smaller than the resistance and/or capacitance of the first resistance compensation pattern RC 1 . For example, the sum of the numbers of data lines DL respectively overlapping the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2  may be smaller than the sum of the numbers of data lines DL respectively overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1 . In detail, referring to  FIG.  7 A , as described above, the sum of the numbers of data lines DL respectively overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be four. Each of the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2  may overlap, in a plan view, one data line (the data line DL 9  of a ninth column in  FIG.  7 A ) except for the data line DL 8  of an eighth column to which the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2  are electrically connected. For example, the sum of the numbers of data lines DL respectively overlapping the first portion P 1 - 2  and the second portion P 2 - 2  of the second resistance compensation pattern RC 2  may be two, which may be smaller than the sum of the number of data lines DL respectively overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1 . 
     The resistances and/or capacitances of the sixth connection pattern CP 6 , the first resistance compensation pattern RC 1 , and the second resistance compensation pattern RC 2  may sequentially decrease. In this manner, a resistance and/or capacitance difference between data lines respectively connected to the sixth connection pattern CP 6 , the first resistance compensation pattern RC 1 , and the second resistance compensation pattern RC 2  may be reduced. 
     Referring to  FIG.  7 B , the sum of the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be larger than the length of the first line L 1 - 6  of the sixth connection pattern CP 6 , but a length difference may not be significant. Compared to the embodiment of  FIG.  7 A , the difference between the sum of the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  and the length of the first line L 1 - 6  of the sixth connection pattern CP 6  illustrated in  FIG.  7 B  may be smaller. For example, a resistance difference between the first resistance compensation pattern RC 1  and the sixth connection pattern CP 6  may reduce. 
     Referring to  FIG.  7 B , the sum of the numbers of data lines DL respectively overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be substantially the same the number of data lines DL overlapping the first line L 1 - 6  of the sixth connection pattern CP 6 . For example, referring to  FIG.  7 B , the first line L 1 - 6  of the sixth connection pattern CP 6  may overlap six data lines (the data lines DL 7  to DL 12  of seventh to 12th columns in  FIG.  7 B ) except for the data line DL 6  of a sixth column to which the first line L 1 - 6  of the sixth connection pattern CP 6  is electrically connected. Each of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may overlap, in a plan view, three data lines (the data lines DL 8  to DL 10  of eighth to 10th columns in  FIG.  7 B ) except for the data line DL 7  of a seventh column to which the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  are electrically connected. For example, the total number of data lines DL overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be six, which may be the same as the number of data lines DL overlapping the first line L 1 - 6  of the sixth connection pattern CP 6 . 
     Compared to the embodiment of  FIG.  7 A , the difference between the sum of the numbers of data lines respectively overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  and the number of data lines overlapping the first line L 1 - 6  of the sixth connection pattern CP 6  illustrated in  FIG.  7 B  may be smaller. For example, a capacitance difference between the first resistance compensation pattern RC 1  and the sixth connection pattern CP 6  may reduce. 
     Therefore, a magnitude relationship between the resistance and capacitance of connection patterns and the resistance and capacitance of resistance compensation patterns is not limited to any one embodiment, provided that resistance and capacitance differences between the resistance compensation patterns and the connection patterns are designed to be minimized. The magnitude relationship between the resistances and capacitances of connection patterns and resistance compensation patterns may be changed according to the number or arrangement of the data lines DL included in the display panel DP. 
       FIG.  8    is a schematic cross-sectional view of a display panel according to an embodiment.  FIG.  8    is a schematic cross-sectional view of the display panel DP taken along line II-IF illustrated in  FIG.  7 A .  FIG.  8    illustrates, as an example, a cross-section corresponding to an area in which the first resistance compensation pattern RC 1  is disposed, and the following descriptions are provided on the basis of the first resistance compensation pattern RC 1 . 
     Referring to  FIG.  8   , the first resistance compensation pattern RC 1  may be disposed in the display area DA. The first resistance compensation pattern RC 1  may overlap the non-emission area NPXA of the display area DA. However, an embodiment is not limited thereto, and a portion of the first resistance compensation pattern RC 1  may overlap the emission area PXA (see  FIG.  4 A ) according to arrangement of the pixel electrode AE (see  FIG.  4 A ). The first resistance compensation pattern RC 1  may include the first portion P 1 - 1 , the second portion P 2 - 1 , and the third portion P 3 - 1 . 
     The first portion P 1 - 1 , the second portion P 2 - 1 , and the third portion P 3 - 1  of the first resistance compensation pattern RC 1  may be disposed on the third insulating layer  30 . The first portion P 1 - 1  and the second portion P 2 - 1  may be disposed on a same layer as the first line L 1 - 6  of the sixth connection pattern CP 6  disposed adjacent to the first resistance compensation pattern RC 1 . 
     Each of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may overlap the data lines DL 8  and DL 9  of eighth and ninth columns. The number of data lines overlapping the first portion P 1 - 1  and the second portion P 2 - 1  may affect the capacitance of the first resistance compensation pattern RC 1 . 
     The number of data lines overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be substantially the same as or slightly different from the number of data lines overlapping the first line L 1 - 6  of the sixth connection pattern CP 6 . For example, referring to  FIG.  8   , each of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may overlap two data lines, and the first resistance compensation pattern RC 1  may have an effect of overlapping four data lines in total. The first line L 1 - 6  of the sixth connection pattern CP 6  may overlap six data lines. 
     As a difference between the number of data lines overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  and the number of data lines overlapping the first line L 1 - 6  of the sixth connection pattern CP 6  decreases, a capacitance difference between the first resistance compensation pattern RC 1  and the sixth connection pattern CP 6  may decrease. A capacitance difference with the sixth connection pattern CP 6  may be controlled by adjusting the number of data lines overlapping the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1 . 
     The sum of the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be substantially the same as or similar to the length of the first line L 1 - 6  of the sixth connection pattern CP 6 . As a difference between the sum of the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  and the length of the first line L 1 - 6  of the sixth connection pattern CP 6  decreases, a resistance difference between the first resistance compensation pattern RC 1  and the sixth connection pattern CP 6  may decrease. A resistance difference with the sixth connection pattern CP 6  may be controlled by adjusting the lengths of the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1 . 
     The third portion P 3 - 1  of the first resistance compensation pattern RC 1  may be disposed on the fourth insulating layer  40 . The third portion P 3 - 1  may be disposed on a same layer as the data lines DL and the second line L 2 - 6  of the sixth connection pattern CP 6 . 
     One end or an end of the first portion P 1 - 1  may be connected to the data line DL 7  of a seventh column through the third contact hole CNT- 3  penetrating the fourth insulating layer  40 . The other end or another end of the first portion P 1 - 1  may be connected to one end or an end of the third portion P 3 - 1  through the fourth contact hole CNT- 4  penetrating the fourth insulating layer  40 . One end or an end of the second portion P 2 - 1  may be connected to the other end or another end of the third portion P 3 - 1  through the fifth contact hole CNT- 5  penetrating the fourth insulating layer  40 , and the other end or another end of the second portion P 2 - 1  may be connected to the data line DL 7  of a seventh column through the sixth contact hole CNT- 6  penetrating the fourth insulating layer  40 . 
     A laminate structure of the first resistance compensation pattern RC 1  is not limited to that illustrated in  FIG.  8   . Although  FIG.  8    illustrates that the first and second portions P 1 - 1  and P 2 - 1  and the third portion P 3 - 1  of the first resistance compensation pattern RC 1  are disposed on different layers, an embodiment is not limited thereto, and the third portion P 3 - 1  may be disposed on a same layer as the first portion P 1 - 1  and the second portion P 2 - 1  so as to be integral. By way of example, the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be disposed on an upper layer than that of the third portion P 3 - 1 . For example, the data lines DL and the third portion P 3 - 1  of the first resistance compensation pattern RC 1  may be disposed on the third insulating layer  30 , and the first portion P 1 - 1  and the second portion P 2 - 1  of the first resistance compensation pattern RC 1  may be disposed on the fourth insulating layer  40  that is an upper layer of the data lines DL. 
       FIG.  9    is a schematic cross-sectional view of a display panel according to an embodiment.  FIG.  9    illustrates schematic cross-sections of the load blocks LB 1  and LB 2  provided in a form of a capacitor. The following descriptions are focused on the load blocks LB 1  and LB 2  provided as capacitors. 
       FIG.  9    illustrates, as an example, the first load block LB 1  provided as a first capacitor and the second load block LB 2  provided as a second capacitor. Hereinafter, for convenience, the first load block LB 1  is referred to as a first capacitor LB 1 , and the second load block LB 2  is referred to as a second capacitor LB 2 . 
     Each of the capacitors LB 1  and LB 2  may be arranged in the non-display area NDA. Each of the capacitors LB 1  and LB 2  may be arranged in the non-display area NDA adjacent to an upper end of the display panel DP. Therefore, the capacitors LB 1  and LB 2 , in a plan view, may be spaced apart from the connection lines DCL (see  FIG.  5   ) arranged in the non-display area NDA adjacent to a lower end of the display panel DP. However, an embodiment is not limited thereto, and the capacitors LB 1  and LB 2  may be arranged in the display area DA. 
     Each of the first and second capacitors LB 1  and LB 2  may be connected to a corresponding data line among the data lines of the second group G 2  (see  FIG.  5   ). The first capacitor LB 1  may be connected to the data line DL 7  (see  FIG.  6 B ) of a seventh column, and the second capacitor LB 2  may be connected to the data line DL 8  (see  FIG.  6 B ) of an eighth column. 
     The first capacitor LB 1  may include the first electrode E 1 - 1  disposed on the third insulating layer  30  and the second electrode E 2 - 1  disposed on the fourth insulating layer  40  and connected to the data line DL 7  (see  FIG.  6 B ) of a seventh column. The second electrode E 2 - 1  of the first capacitor LB 1  may be connected to the data line DL 7  (see  FIG.  6 B ) of a seventh column on a same layer so as to form a shape of one piece. 
     The second capacitor LB 2  may include the first electrode E 1 - 2  disposed on the third insulating layer  30  and the second electrode E 2 - 2  disposed on the fourth insulating layer  40 . The second electrode E 2 - 2  of the second capacitor LB 2  may be connected to the data line DL 8  (see  FIG.  6 B ) of an eighth column in a plan view. 
     A capacitance of the first capacitor LB 1  may be different from a capacitance of the second capacitor LB 2 . The capacitance of the first capacitor LB 1  connected to the data line DL 7  (see  FIG.  5   ) of a seventh column disposed closest to the data lines of the first group G 1  (see  FIG.  5   ) may be larger than the capacitance of the second capacitor LB 2  connected to the data line DL 8  (see  FIG.  6 B ) of an eighth column. Planar area sizes of the electrodes included in the first and second capacitors LB 1  and LB 2  may affect the capacitances of the first and second capacitors LB 1  and LB 2 . Therefore, a planar area size A 1  of the electrodes E 1 - 1  and E 2 - 1  of the first capacitor LB 1  may be larger than a planar area size A 2  of the electrodes E 1 - 2  and E 2 - 2  of the second capacitor LB 2 . 
     The capacitances of the sixth connection pattern CP 6  (see  FIG.  5   ), the first capacitor LB 1 , and the second capacitor LB 2  may sequentially reduce. In this manner, a capacitance difference between the sixth connection pattern CP 6  (see  FIG.  5   ), the first capacitor LB 1 , and the second capacitor LB 2  may be reduced. 
       FIG.  10    is an enlarged schematic plan view of a display panel according to an embodiment.  FIG.  10    illustrates an enlarged schematic plan view of one area or an area of the display panel DP, which corresponds to an area between the left boundary of the display area DA and the right boundary of the display area DA, and in which the connection patterns CP 1 , CP 2 , CP n+1 , and CP 2n  are disposed.  FIG.  10    may include substantially the same configuration as that of the display panel DP illustrated in  FIG.  7 A , and only differs from  FIG.  7 A  in terms of a size of an illustrated area. 
     Referring to  FIG.  10   , the data lines DL 1  to DL 6  of the first group G 1  disposed on the left side and the connection patterns CP 1  to CP 6  connected thereto may form a symmetric shape with the data lines DL 3n+m+1  to DL 4n+m  of the first group G 1  disposed on the right side and the connection patterns CP n+1  to CP 2n  connected thereto with respect to a virtual center line extending in the second direction DR 2 . The data lines DL 7  to DL 12  of the second group G 2  disposed on the left side and the resistance compensation patterns RC 1  and RC 2  connected thereto may form a symmetric shape with the data lines DL 2n+m+1  to DL 3n+m  of the second group G 2  disposed on the right side and the resistance compensation patterns connected thereto with respect to the virtual center line extending in the second direction DR 2 . 
     The connection patterns CP that electrically connect the data driver DDV (see  FIG.  2   ) and the data lines DL disposed adjacent to the two boundaries of the display area DA may be connected to the data lines DL via the display area DA, thus reducing a size of the non-display area NDA in which wirings are disposed. As a result, the electronic apparatus ED having a relatively light weight and a wide display area DA may be provided to a user. 
     The connection patterns CP may have substantially the same resistance and capacitance, and may reduce the resistance and capacitance differences between the data lines of the first group G 1  connected to the connection patterns CP, thereby preventing the degradation of display quality. 
     The data lines of the second group G 2  may be not connected to the connection patterns CP and may be arranged in the first direction DR 1  from the data lines of the first group G 1  and at least one of the data lines of the second group G 2  may be connected to a load block. The load blocks may reduce the resistance and capacitance differences between the data lines of the first group G 1  and the data lines of the second group G 2 . In this manner, the degradation of display quality due to sharp changes in resistance and capacitance between data lines may be prevented. 
     Since a display panel of an embodiment may include a connection pattern connected to signal lines, a size of an area in which the signal lines are disposed may be reduced, and a phenomenon of signal delay due to an increase in resistance and capacitance may be resolved. 
     Since a display panel of an embodiment may include a load block connected to a signal line, a phenomenon of degradation of display quality due to a sharp change in resistance and capacitance may be resolved. 
     Although embodiments have been described, it is understood that the disclosure should not be limited to these embodiments but various changes and modifications can be made by one of ordinary skill in the art within the spirit and scope of the disclosure and as hereinafter claimed.
