[0013] The advantages and features of the present invention, and methods for achieving them, will become more apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various different forms. The embodiments are provided solely so that this disclosure will be complete and will fully convey the scope of the invention to those skilled in the art.

[0014] The shapes, areas, ratios, angles, numbers, etc. disclosed in the drawings for illustrating the embodiments of this specification are illustrative only and are not intended to limit the scope of this specification. The same reference symbols refer to the same elements throughout this specification. Furthermore, when describing this specification, if it is deemed that a detailed description of related prior art would unnecessarily obscure the gist of this specification, such a detailed description will be omitted. When using words such as "include," "have," and "be made" in this specification, other parts may be added unless "only" is used. When describing an element in the singular, this also includes the plural unless otherwise explicitly stated.

[0015] When interpreting elements, they are interpreted as including a margin of error even if there is no other explicit description.

[0016] When describing a positional relationship, for example, when describing the positional relationship of two parts using "above," "at the top," "below," "next to," etc., one or more other parts may be located between the two parts, as long as "immediately" or "directly" is not used.

[0017] When an element or layer is referred to as "on" another element or layer, it includes the case where the element or layer is directly on top of the other element or layer, or where there are other layers or elements interposed therebetween.

[0018] Furthermore, although terms such as "first," "second," etc. are used to describe various components, these components are not limited by these terms. These terms are used merely to distinguish one component from another. Therefore, a first component referred to below may be a second component within the technical concept of this specification.

[0019] Like reference numbers refer to like elements throughout the specification.

[0020] The area and thickness of each component shown in the drawings are shown for convenience of explanation, and the present specification is not necessarily limited to the area and thickness of the components shown.

[0021] The features of the various embodiments of this specification may be partially or wholly combined or combined with each other, may be technically interlocked and driven in various ways, and each embodiment may be implemented independently of the other or may be implemented together in a related relationship.

[0022] In the following, the present specification will be described with reference to the drawings.

[0023] Fig. 1 is an exemplary plan view of a display device according to an embodiment of the present specification. Fig. 2 is an exemplary plan view of a display device according to an embodiment of the present specification. For convenience of explanation, Figs. 1 and 2 only show a substrate 110 and a plurality of flexible film COFs among various components of a display device 100.

[0024] The substrate 110 is a base member for supporting various components of the display device 100 and may be made of an insulating material. For example, the substrate 110 may be made of a plastic material such as polyimide (PI) or glass, but is not limited thereto.

[0025] The substrate 110 includes a display area AA and a non-display area NA.

[0026] The display area AA is an area where an image is displayed. Pixels each consisting of a plurality of sub-pixels may be arranged in the display area AA to display an image. For example, a pixel may be composed of a plurality of sub-pixels each including a light-emitting element and a driving circuit, and may display an image.

[0027] The display area AA may have an irregular side, where at least one of the four sides of the display area AA has an irregular structure. That is, referring to FIG. 1, the active area AA has a first side FS, a second side SS, a third side TS, and a fourth side HTRS. The second side SS faces the third side TS, and the first side FS is located between the second side SS and the third side TS. The fourth side HTRS faces the first side FS. The irregular side HTRS refers to a side that is not a straight side but has a curved shape. For example, referring to FIG. 1, the lower side of the four sides of the display area AA may be the irregular side HTRS. That is, the irregular side HTRS located at the bottom of the display area AA is recessed toward the top of the display area AA, so that a recessed irregular structure corresponding to the irregular side HTRS may be defined. 1, the irregular structure is shown as a rectangular recessed structure, but is not limited thereto, and the irregular structure is a structure generated by the irregular side HTRS, and may refer to a shape that is difficult to define as a polygon due to a deformation of the polygon, such as a circle, triangle, square, rhombus, pentagon, hexagon, etc. Since pixels are not arranged in the position where the irregular side HTRS is recessed, no image is displayed, and this can be defined as a notch area (NTA).

[0028] The display area AA may include a plurality of first regions A1 and at least one second region A2 divided into a grid pattern. The plurality of first regions A1 and at least one second region A2 may be regions in which gate drivers are distributed. The plurality of first regions A1 may all have a uniform area, and the at least one second region A2 may be positioned to correspond to the notch region NTA and have a smaller area than the plurality of first regions A1. For design convenience, the second region A2 may be positioned adjacent to the notch region NTA. While FIG. 1 illustrates the display area AA as including one second region A2, this is not intended to be limiting, and two or more second regions A2 may be disposed depending on the shape, position, and size of the notch region. Referring to FIG. 2, the display area AA may include a plurality of first regions A1 and a plurality of second regions A2. For example, a row region corresponding to the notch region NTA may include one first region A1 and a plurality of second regions A2. However, this is not intended to be limiting.

[0029] The non-display area NA is an area where no image is displayed, and is an area where various wirings for driving the sub-pixels arranged in the display area AA are arranged. The non-display area may be called a bezel area.

[0030] A plurality of flexible film COFs are disposed at one end of the substrate 110. The plurality of flexible film COFs may be electrically connected to one end of the substrate 110. The plurality of flexible film COFs are films in which various components are disposed on a ductile base film and which supply signals to a plurality of sub-pixels in the display area AA. One end of the plurality of flexible film COFs is disposed in the non-display area NA of the substrate 110, and the plurality of flexible film COFs may supply data voltages, etc. to a plurality of sub-pixels in the display area AA. While FIG. 1 illustrates four flexible film COFs, the number of the plurality of flexible film COFs may vary depending on the design and is not limited thereto.

[0031] Meanwhile, a driving IC such as a data driver IC may be disposed on each of the flexible film COFs. The driving IC is a component that processes data for displaying an image and a driving signal for processing the data. The driving IC may be disposed in a chip-on-glass (COG), chip-on-film (COF), tape carrier package (TCP), or other manner depending on the mounting method. For the sake of convenience, this specification describes the driving IC as being mounted on each of the flexible film COFs in a chip-on-film manner, but the present invention is not limited thereto.

[0032] 3 is an exemplary circuit diagram of a pixel circuit of a display device according to an embodiment of the present specification. A pixel PX may include multiple sub-pixels each exhibiting a different color, and a pixel circuit corresponding to each of the multiple sub-pixels. FIG. 3 shows an example of a pixel circuit for one sub-pixel arranged in the pixel PX.

[0033] Referring to FIG. 3, the pixel circuit may include eight transistors and one capacitor.

[0034] The pixel circuit may include a driving transistor DT, a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, a seventh transistor T7, and a capacitor Cstg.

[0035] The eight transistors included in the pixel circuit may be n-type transistors or p-type transistors. In the case of p-type transistors, the low level voltage of each driving signal may be a voltage that turns on the TFT, and the high level voltage of each driving signal may be a voltage that turns off the TFT.

[0036] Here, the low-level voltage may correspond to a pre-specified voltage lower than the high-level voltage. For example, the low-level voltage may include a voltage within the range of -8V to -12V. The high-level voltage may correspond to a pre-specified voltage higher than the low-level voltage. For example, the high-level voltage may include a voltage within the range of 12V to 16V. Depending on the embodiment, the low-level voltage may be referred to as a first voltage, and the high-level voltage may be referred to as a second voltage. In such a case, the first voltage may be lower than the second voltage. However, the above-mentioned ranges of the low-level voltage and the high-level voltage are merely examples and are not limited thereto.

[0037] Hereinafter, the first electrode or second electrode of a transistor may refer to a source electrode or a drain electrode. However, the terms first electrode and second electrode are merely terms used to distinguish between the electrodes and do not limit what each electrode corresponds to. Also, the first electrode for each electrode may not refer to the same electrode. For example, the first electrode of the first transistor T1 may refer to the source electrode of the first transistor T1, and the first electrode of the sixth transistor T6 may refer to the drain electrode of the sixth transistor T6.

[0038] The driving transistor DT may be connected to a first transistor T1 connected to the first light emitting element ED1 and a second transistor T2 connected to the second light emitting element ED2. For example, a second electrode of the driving transistor DT may be connected to the first transistor T1 and the second transistor T2.

[0039] The driving transistor DT may be connected to a high-potential power supply line that provides a high-potential power supply voltage ELVDD. For example, a first electrode of the driving transistor DT may be connected to the high-potential power supply line. When the driving transistor DT is turned on, the high-potential power supply voltage ELVDD provided through the high-potential power supply line may be transferred from the first electrode to the second electrode of the driving transistor DT.

[0040] The first transistor T1 may be connected to at least one of the first light emitting element ED1, the second transistor T2, the fourth transistor T4, and the fifth transistor T5.

[0041] For example, a first electrode of the first transistor T1 may be connected to the second transistor T2 and the fourth transistor T4. A second electrode of the first transistor T1 may be connected to the first light emitting element ED1 and the fifth transistor T5. A gate electrode of the first transistor T1 may be connected to a wide-angle signal line to which a wide-angle signal CS1 is applied. The first transistor T1 may be turned on or off by the wide-angle signal CS1 provided through the wide-angle signal line. Therefore, when the first transistor T1 is turned on, a voltage through the driving transistor DT may be applied to the first light emitting element ED1 (e.g., the anode electrode of the first light emitting element ED1).

[0042] Here, the wide-view signal CS1 is provided by a mode control section (or a mode control circuit) and can control the driving (or light emission) of the first light-emitting element ED1 on which the first lens is disposed.

[0043] The second transistor T2 may be connected to at least one of the second light emitting element ED2, the first transistor T1, the fourth transistor T4, and the sixth transistor T6.

[0044] For example, a first electrode of the second transistor T2 may be connected to the first transistor T1 and the fourth transistor T4. A second electrode of the second transistor T2 may be connected to the sixth transistor T6 and the second light-emitting element ED2. A gate electrode of the second transistor T2 may be connected to a narrow-viewpoint signal line to which a narrow-viewpoint signal CS2 is applied. The second transistor T2 may be turned on or off by the narrow-viewpoint signal CS2 provided through the narrow-viewpoint signal line. Therefore, when the second transistor T2 is turned on, a voltage through the driving transistor DT may be applied to the second light-emitting element ED2 (e.g., the anode electrode of the second light-emitting element ED2).

[0045] Here, the narrow-view signal CS2 is provided by the mode control section (or mode control circuit), and can control the driving (or light emission) of the second light-emitting element ED2 on which the second lens is disposed.

[0046] In the embodiment, a first lens may be disposed on the first light-emitting element ED1. The viewing angle of the region where the first light-emitting element ED1 is disposed may correspond to a first value due to the first lens. For example, the viewing angle of the region where the first light-emitting element ED1 is disposed may be equal to or greater than the first value. A second lens may be disposed on the second light-emitting element ED2. The viewing angle of the region where the second light-emitting element ED2 is disposed due to the second lens may correspond to a second value. The second value may be smaller than the first value. For example, the viewing angle of the region where the second light-emitting element ED2 is disposed may be equal to or smaller than the second value.

[0047] In the embodiment, the region where the first light-emitting element ED1 of the pixel circuit is arranged may have a first viewing angle value that provides light to a range corresponding to the passenger seat and the driver's seat next to the passenger seat, and the region where the second light-emitting element ED2 is arranged may have a second viewing angle value that provides light to a range corresponding to the passenger seat.

[0048] For example, content (or an image) provided through the first light-emitting element ED1 of the pixel PX can be shared with the user and people nearby in the first direction. When content is provided through the first light-emitting element ED1, it is a mode in which content is provided in a first viewing angle range that is wider than a second viewing angle range provided by the second light-emitting element ED2, and can be referred to as a first mode. Also, content provided by the second light-emitting element ED2 does not need to be shared with people nearby the user. When content is provided through the second light-emitting element ED2, it is a mode in which content is provided in a second viewing angle range that is narrower than the first viewing angle range provided by the first light-emitting element ED1, and can be referred to as a second mode.

[0049] The third transistor T3 may be connected to at least one of the fifth transistor T5, the sixth transistor T6, the seventh transistor T7, and the capacitor Cstg.

[0050] For example, a first electrode of the third transistor T3 may be connected to a reference voltage line that supplies a reference voltage Vref. A first electrode of the third transistor T3 may be connected to the fifth transistor T5 and the sixth transistor T6. A second electrode of the third transistor T3 may be connected to the sixth transistor T6 and the capacitor Cstg. A gate electrode of the third transistor T3 may be connected to an emission signal line that supplies an emission signal EM. The third transistor T3 may be turned on or off by the emission signal EM. Therefore, when the third transistor T3 is turned on, the reference voltage Vref may be applied to the first electrode of the capacitor Cstg.

[0051] The fourth transistor T4 may be connected to at least one of the driving transistor DT, the first transistor T1, the second transistor T2, and the capacitor Cstg.

[0052] For example, a first electrode of the fourth transistor T4 may be connected to the driving transistor DT and the capacitor Cstg. A second electrode of the fourth transistor T4 may be connected to the driving transistor DT, the first transistor T1, and the second transistor T2. A gate electrode of the fourth transistor T4 may be connected to the second scan line for the second scan signal SCAN2. The fourth transistor T4 may receive the second scan signal SCAN2 and be turned on or off in response to the second scan signal SCAN2. Therefore, when the fourth transistor T4 is turned on, the gate electrode and the second electrode of the driving transistor DT may be diode-connected and connected in a diode configuration.

[0053] The fifth transistor T5 may be connected to at least one of the first transistor T1, the third transistor T3, and the first light emitting element ED1.

[0054] For example, a first electrode of the fifth transistor T5 may be connected to the third transistor T3 and a reference voltage line that supplies the reference voltage Vref. A second electrode of the fifth transistor T5 may be connected to the first transistor T1 and the first light emitting element ED1. A gate electrode of the fifth transistor T5 may be connected to the second scan line. Thus, the fifth transistor T5 may receive the second scan signal SCAN2 and be turned on or off in response to the second scan signal SCAN2. Therefore, when the fifth transistor T5 is turned on, the reference voltage Vref may be applied to the first light emitting element ED1 (e.g., the anode electrode of the first light emitting element ED1).

[0055] The sixth transistor T6 may be connected to at least one of the second transistor T2, the third transistor T3, and the second light emitting element ED2.

[0056] For example, a first electrode of the sixth transistor T6 may be connected to the third transistor T3 and a reference voltage line that supplies the reference voltage Vref. A second electrode of the sixth transistor T6 may be connected to the second transistor T2 and the second light-emitting element ED2. A gate electrode of the sixth transistor T6 may be connected to the second scan line. Thus, the sixth transistor T6 may receive a second scan signal SCAN2 and be turned on or off in response to the second scan signal SCAN2. Therefore, when the sixth transistor T6 is turned on, the reference voltage Vref may be applied to the second light-emitting element ED2 (e.g., the anode electrode of the second light-emitting element ED2).

[0057] The seventh transistor T7 may be connected to at least one of the third transistor T3 and the capacitor Cstg.

[0058] For example, a first electrode of the seventh transistor T7 may be connected to a data line supplying the data voltage Vdata. A second electrode of the seventh transistor T7 may be connected to the third transistor T3 and the capacitor Cstg. A gate electrode of the seventh transistor T7 may be connected to a first scan line supplying the first scan signal SCAN1. The seventh transistor T7 may receive the first scan signal SCAN1 and be turned on or off in response to the first scan signal SCAN1. Therefore, when the seventh transistor T7 is turned on, the data voltage Vdata may be applied to the first electrode of the capacitor Cstg.

[0059] The first light emitting element ED1 and the second light emitting element ED2 may be connected to a low potential power supply line that supplies a low potential power supply voltage ELVSS. For example, the cathode electrode of the first light emitting element ED1 and the cathode electrode of the second light emitting element ED2 may be connected to the low potential power supply line and receive the low potential power supply voltage ELVSS. The low potential power supply voltage may be a ground voltage (e.g., 0V (volt)). For example, the cathode electrode of the first light emitting element ED1 and the cathode electrode of the second light emitting element ED2 may receive a voltage corresponding to ground, but is not limited thereto.

[0063] A buffer layer 111 may be disposed on the substrate 110. The buffer layer 111 may be formed on the entire surface of the substrate 110. The buffer layer 111 may be composed of a single layer of silicon nitride (SiNx) or silicon oxide (SiOx) or multiple layers thereof. The buffer layer 111 may improve adhesion between the substrate 110 and a layer formed on the buffer layer 111. The buffer layer 111 is not an essential component and may be omitted depending on the type and material of the substrate 110, the structure and type of the transistor, etc.

[0067] A first gate electrode GE1 of the first transistor T1 may be disposed on the gate insulating layer 112. The first gate electrode GE1 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof. The first gate electrode GE1 may be formed on the gate insulating layer 112 to overlap with the first active layer ACT1 of the first transistor T1.

[0068] A first interlayer insulating layer 113 may be disposed on the gate insulating layer 112 and the first gate electrode GE1. The first interlayer insulating layer 113 may be composed of a single layer of silicon nitride (SiNx) or silicon oxide (SiOx) or multiple layers thereof. A contact hole may be formed in the first interlayer insulating layer 113 to expose the first active layer ACT1 of the first transistor T1.

[0069] A second interlayer insulating layer 114 may be disposed on the first interlayer insulating layer 113.

[0124] Figure 8 is a schematic diagram illustrating the second region A2 of Figure 1. For ease of explanation, Figure 8 only shows the first scan driver region SDA1, the second scan driver region SDA2, the light emitting driver region EMA, and a plurality of gate blocks GB arranged in the second region A2 of Figure 1. In the following, the remaining configuration is the same as that of Figure 6 except for the plurality of gate blocks GB, which is the difference, and therefore will not be described again.

[0125] 8, the second region A2 may have a smaller area than the first region A1 due to the notch region NTA. Therefore, the number of gate blocks GB arranged in each of the first scan driver region SDA1, the second scan driver region SDA2, and the light emitting driver region EMA may be smaller than that of the first region A1. For example, the first scan driver region SDA1, the second scan driver region SDA2, and the light emitting driver region EMA arranged in the second region A2 may each have two first gate blocks GB1 and two second gate blocks GB2 arranged in the column direction. While FIG. 6 shows one less first gate block GB1 than FIG. 4, the number of first gate blocks GB1 and second gate blocks GB2 arranged in the second region A2 may vary depending on the area and design, and is not limited thereto.

The first compensation pattern 130 may extend in the row direction from the high-potential power supply line VDDL and be integrated with the high-potential power supply line VDDL.

[0131] The first compensation pattern 130 may have a constant width from the top to the bottom of the second gate block GB2. The width of the high potential power line VDDL and the first compensation pattern 130 arranged in the second gate block GB2 in the second region A2 may be larger than the width of the high potential power line VDDL arranged in the second gate block GB2 in the first region A1. That is, the area of ​​the high potential power line VDDL and the first compensation pattern 130 arranged in the second gate block GB2 in the second region A2 overlapping with the plurality of gate lines GL may be larger than the area of ​​the high potential power line VDDL and the plurality of gate lines GL overlapping with the second gate block GB2 in the first region A1.

[0134] The gate line GL may be formed in the same layer and made of the same material as the first gate electrode GE1 of the first transistor T1. For example, the gate line GL may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0135] A first compensation pattern 130 may be disposed on the second interlayer insulating layer 114 .

[0136] The first compensation pattern 130 may be disposed on the second interlayer insulating layer 114 to overlap the gate line GL. The first compensation pattern 130 may be formed in the same layer and made of the same material as the first source electrode SE1 and the first drain electrode DE1 of the first transistor T1. For example, the first compensation pattern 130 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0137] In the conventional display device, the substrate is a rectangular substrate without any irregular structure on any side, and the output characteristics of the gate signal output from the gate driver are the same at all positions in the display area. However, in the case of an irregular display device in which one or more of the four sides of the substrate that is not a rectangular substrate have an irregular structure, the output characteristics of the gate signal are the same in the area without the irregular structure, but the output characteristics of the gate signal are different in the area with the irregular structure compared to the area without the irregular structure, resulting in non-uniform brightness.

[0138] Therefore, in a display device 100 according to an embodiment of the present specification, a display area AA is divided into a plurality of first areas A1 and at least one second area A2 arranged to correspond to the notch area. A plurality of gate blocks GB1 and GB2, in which gate drivers are divided, are arranged in each of the first area A1 and the second area A2. The second area A2, which is smaller in area than the first area A1 due to the notch area, has fewer gate blocks GB1 and GB2 than the first area A1, resulting in different gate signal output characteristics. Accordingly, a first compensation pattern 130 is arranged in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 arranged in the second area A2 to overlap with the gate line GL. A capacitor is formed between the gate line GL and the first compensation pattern 130, thereby compensating for RC delays of gate signals output from the plurality of gate blocks GB1 and GB2 arranged in the second area A2. That is, the output characteristics of the gate signals output from the gate blocks GB1 and GB2 arranged in the second region A2 can be made the same as the output characteristics of the gate signals output from the gate blocks GB1 and GB2 arranged in the first region A1. Therefore, in the display device 100 according to an embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure can be compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0139] Furthermore, if a gate driver that outputs a gate signal and a compensation pattern for compensating for RC delay deviation due to a non-uniform structure are disposed in the non-display area, the area of ​​the non-display area increases, resulting in a problem of an increased bezel area.

[0140] Therefore, in the display device 100 according to an embodiment of the present specification, a plurality of gate blocks GB1, GB2 in which the gate drivers are divided and arranged are distributed in the display area AA, and a compensation pattern 130 for compensating for the RC delay deviation is arranged in at least one gate block GB2 of the plurality of gate blocks GB1, GB2 arranged in the second area A2, thereby minimizing the area of ​​the non-display area NA. Therefore, in the display device 100 according to an embodiment of the present specification, the gate drivers and the compensation pattern 130 are arranged within the display area, thereby minimizing the bezel area.

[0141] 11 is an enlarged plan view of one of the gate blocks of a display device according to another embodiment of the present specification. Fig. 11 shows an enlarged view of a portion of a second gate block GB2 among the gate blocks GB of a display device 200 according to another embodiment of the present specification.

[0142] Referring to FIG. 11, a high potential power supply line VDDL, a first compensation pattern 230, and a plurality of gate lines GL may be arranged in the second gate block GB2 arranged in the second region A2.

[0143] The high-potential power supply wiring VDDL can be arranged in the second gate block GB2 so as to extend in the column direction and intersect with the plurality of gate wirings GL.

[0144] The first compensation pattern 230 may be arranged in the second gate block GB2 to extend in the column direction and overlap with the gate lines GL. The first compensation pattern 230 may extend in the row direction from the high-potential power supply line VDDL and be integrated with the high-potential power supply line VDDL. Therefore, the first compensation pattern may function as the high-potential power supply line, and the high-potential power supply line may also function as the first compensation pattern.

[0145] The first compensation pattern 230 may have a constant width from the top to the bottom of the second gate block GB2. The width of the high potential power line VDDL and the first compensation pattern 230 arranged in the second gate block GB2 in the second region A2 may be larger than the width of the high potential power line VDDL arranged in the second gate block GB2 in the first region A1. That is, the area of ​​the high potential power line VDDL and the first compensation pattern 230 arranged in the second gate block GB2 in the second region A2 overlapping with the plurality of gate lines GL may be larger than the area of ​​the high potential power line VDDL and the plurality of gate lines GL overlapping with the second gate block GB2 in the first region A1.

[0146] The plurality of gate lines GL may extend in the row direction in the second gate block GB2 and be arranged parallel to and spaced apart from each other in the column direction. The width of the portions of the plurality of gate lines GL overlapping with the first compensation pattern 230 may be greater than the width of the portions of the plurality of gate lines GL not overlapping with the first compensation pattern 230. For example, the portions of the plurality of gate lines GL overlapping with the high potential power supply line VDDL and the first compensation pattern 230 may be greater in width than the portions not overlapping with the high potential power supply line VDDL and the first compensation pattern 230. For example, the portions of the plurality of gate lines GL having a greater width may be portions of the plurality of gate lines GL overlapping with the high potential power supply line VDDL and the first compensation pattern 230 extending in the column direction.

[0147] In addition, the width of the wide portion of each of the gate lines GL may differ depending on the output of the gate driver connected to each gate line GL. For example, if the output of the gate driver connected to a gate line GL is greater than the output of the gate driver connected to another gate line GL, the width of the portion of the corresponding gate line GL overlapping with the high potential power line VDDL and the first compensation pattern 230 may be wider than the width of the portion of the other gate lines GL overlapping with the high potential power line VDDL and the first compensation pattern 230.

[0148] In a display device 200 according to another embodiment of the present specification, a first compensation pattern 230 is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second region A2 so as to overlap with the gate line GL. A capacitor is formed between the gate line GL and the first compensation pattern 230, thereby compensating for the RC delay of the gate signals output from the plurality of gate blocks GB1 and GB2 disposed in the second region A2. Therefore, in the display device 200 according to another embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure is compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0149] In a display device 200 according to another embodiment of the present specification, a plurality of gate blocks GB1 and GB2, into which a gate driver is divided, are distributed in the display area AA, and a first compensation pattern 230 for compensating for an RC delay deviation is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second area A2, thereby minimizing the area of ​​the non-display area NA. Therefore, in a display device 200 according to another embodiment of the present specification, the gate driver and the first compensation pattern 230 are disposed within the display area, thereby minimizing the bezel area.

[0150] In a display device 200 according to another embodiment of the present specification, the width of a portion of the plurality of gate lines GL overlapping with the first compensation pattern 230 may be greater than the width of a portion of the plurality of gate lines GL not overlapping with the first compensation pattern 230. In this case, the width of the portion overlapping with the first compensation pattern 230 can be designed to vary depending on the output of the gate driver to which the gate line GL is connected. Thus, RC delay can be compensated for in accordance with the output characteristics of the gate signals output from the plurality of gate blocks GB1 and GB2 arranged in the second region A2. Therefore, in the display device 200 according to another embodiment of the present specification, RC delay can be compensated for depending on the output of the gate driver to which the gate line GL is connected, thereby improving design flexibility and display quality.

[0151] FIG. 12 is an enlarged plan view of one of the gate blocks of a display device according to still another embodiment of the present disclosure.

[0152] FIG. 12 shows an enlarged view of a part of a second gate block GB2 among a plurality of gate blocks GB of a display device 300 according to still another embodiment of the present specification.

[0153] Referring to FIG. 12, the second gate block GB2 disposed in the second region A2 may include a high potential power supply line VDDL, a first compensation pattern 230, and a plurality of gate lines GL.

[0154] The plurality of gate lines GL may extend in the row direction in the second gate block GB2 and may be arranged in parallel to each other and spaced apart from each other in the column direction. The plurality of gate lines GL may have a uniform width.

[0155] The high-potential power supply wiring VDDL may be arranged to extend in the column direction in the second gate block GB2 and intersect with the gate wirings GL. The high-potential power supply wiring VDDL may have a constant width from the top end to the bottom end of the second gate block GB2.

[0156] The first compensation pattern 330 may be arranged in the second gate block GB2 to extend in the column direction and overlap with the gate lines GL. The first compensation pattern 330 may extend in the row direction from the high potential power supply line VDDL and may be integrated with the high potential power supply line VDDL.

[0157] The width of the high potential power supply wiring VDDL and the first compensation pattern 230 arranged in the second gate block GB2 in the second region A2 may be larger than the width of the high potential power supply wiring VDDL arranged in the second gate block GB2 in the first region A1. That is, the area of ​​the high potential power supply wiring VDDL and the first compensation pattern 230 arranged in the second gate block GB2 in the second region A2 overlapping with the plurality of gate wirings GL may be larger than the area of ​​the high potential power supply wiring VDDL and the plurality of gate wirings GL overlapping with the second gate block GB2 in the first region A1.

[0158] Meanwhile, the width of the first compensation pattern 330 may vary depending on the position. Because the high potential power line VDDL is constant, the combined width of the high potential power line VDDL and the first compensation pattern 330 may vary depending on the position. The width of the first compensation pattern 330 may vary depending on the output of the gate driver connected to each gate line GL. For example, if the output of the gate driver connected to a gate line GL is greater than the output of the gate driver connected to another gate line GL, the width of the first compensation pattern 330 overlapping the corresponding gate line GL may be wider than the width of the first compensation pattern 330 overlapping the other gate line GL. Although FIG. 12 illustrates a configuration in which the widths of the high potential power line VDDL and the first compensation pattern 330 become narrower at the center toward the bottom, this is not limiting.

[0159] Therefore, in a display device 300 according to another embodiment of the present specification, a first compensation pattern 330 is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second region A2 so as to overlap with the gate line GL, and a capacitor is formed between the gate line GL and the first compensation pattern 330, thereby compensating for the RC delay of the gate signals output from the plurality of gate blocks GB1 and GB2 disposed in the second region A2. Therefore, in the display device 300 according to another embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure is compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0160] In a display device 300 according to another embodiment of the present specification, a plurality of gate blocks GB1 and GB2, into which a gate driver is divided, are distributed in the display area AA, and a first compensation pattern 330 for compensating for an RC delay deviation is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second area A2, thereby minimizing the area of ​​the non-display area NA. Therefore, in a display device 300 according to another embodiment of the present specification, the gate driver and the first compensation pattern 330 are disposed within the display area, thereby minimizing the bezel area.

[0161] In a display device 300 according to another embodiment of the present disclosure, the width of the gate lines GL is constant, and the width of the first compensation pattern 330 overlapping the gate lines GL may vary depending on the position. Therefore, various capacitors may be formed between the gate lines GL and the first compensation pattern 330, and RC delay may be compensated for in accordance with the output characteristics of the gate signals output from the gate blocks GB1 and GB2 arranged in the second region A2. Therefore, in the display device 300 according to another embodiment of the present disclosure, RC delay may be compensated for according to the output of the gate driver to which the gate lines GL are connected, thereby improving design flexibility and display quality.

Figure 14 is a cross-sectional view of a second gate block GB2 among the gate blocks GB of a display device 400 according to another embodiment of the present disclosure.

The first compensation pattern 430 may overlap the gate line GL to form a capacitor between the first compensation pattern 430 and the gate line GL. The first compensation pattern 430 may be formed in the same layer and made of the same material as the first source electrode SE1 and first drain electrode DE1 of the first transistor T1 and the second source electrode SE2 and second drain electrode DE2 of the second transistor T2. For example, the first compensation pattern 430 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0200] Therefore, in a display device 400 according to another embodiment of the present specification, a first compensation pattern 430 is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second region A2 so as to overlap with the gate line GL, and a capacitor is formed between the gate line GL and the first compensation pattern 430, thereby compensating for the RC delay of the gate signals output from the plurality of gate blocks GB1 and GB2 disposed in the second region A2. Therefore, in the display device 400 according to another embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure is compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0201] In a display device 400 according to another embodiment of the present specification, a plurality of gate blocks GB1, GB2 into which a gate driver is divided are distributed in the display area AA, and a first compensation pattern 430 for compensating for an RC delay deviation is disposed in at least one gate block GB2 of the plurality of gate blocks GB1, GB2 disposed in the second area A2, thereby minimizing the area of ​​the non-display area NA. Therefore, in a display device 400 according to another embodiment of the present specification, the gate driver and the first compensation pattern 430 are disposed within the display area, thereby minimizing the bezel area.

[0202] Fig. 15 is an exemplary plan view of a display device according to still another embodiment of the present disclosure, Fig. 16 is a plan view of one of the gate blocks in the fourth region of Fig. 15, and Fig. 17 is a cross-sectional view taken along XV-XV' of Fig. 16.

[0203] For ease of explanation, Fig. 15 shows only the substrate 110 and the plurality of flexible films COF among the various components of the display device 500. In Fig. 15, the remaining configuration except for the plurality of third areas A3 and the plurality of fourth areas A4 of the display area AA is the same as Fig. 1, and therefore detailed description thereof will be omitted.

[0204] Referring to FIG. 15, the display area AA may include a plurality of third areas A3 and a plurality of fourth areas A4. The plurality of third areas A3 and the plurality of fourth areas A4 may be areas in which gate drivers are distributed. The plurality of third areas A3 may be areas having a first width in the column direction, and the plurality of fourth areas A4 may be areas arranged to correspond to the notch areas NTA and having a second width smaller than the first width of the plurality of third areas A3. For example, the fourth area A4 may be an area whose width in the column direction is smaller than the width of the third areas A3 due to the notch areas NTA. The plurality of third areas A3 may be the remaining areas excluding the fourth area A4.

[0205] 16 shows only the 1-1 gate block GB1-1 of the multiple gate blocks GB arranged in the fourth region A4. In FIG. 16, the remaining configuration except for the clock wiring CLKL and the second compensation pattern 540 is the same as in FIG. 5, so detailed description thereof will be omitted.

[0206] 16, a clock line CLKL may be connected to a plurality of gate blocks GB. A first-first gate block GB1-1 among the plurality of gate blocks GB may be provided with a clock line CLKL extending in the column direction to transmit a clock signal. The clock line CLKL may be arranged to intersect with a plurality of gate lines GL arranged in the row direction.

[0207] The second compensation pattern 540 may overlap the clock line CLKL. The second compensation pattern 540 may be disposed between the plurality of gate lines GL of the 1-1 gate block GB1-1. The second compensation pattern 540 may be disposed below the clock line CLKL to overlap the clock line CLKL. Although FIG. 16 illustrates the second compensation pattern being disposed below the clock line, the second compensation pattern 540 may be disposed above the clock line CLKL to overlap the clock line CLKL. For design convenience, the second compensation pattern 540 may be disposed adjacent to the notch region NTA. A constant voltage may be applied to the second compensation pattern 540. For example, the second compensation pattern 540 may be electrically connected to one of a low-potential power line VSSL to which a low-potential power supply is applied and a high-potential power line VDDL to which a high-potential power supply is applied, and a low-potential power supply or a high-potential power supply may be applied.

[0208] Meanwhile, the second compensation pattern 540 has a constant width, and the length of the clock line CLKL overlapping with the second compensation pattern may vary depending on the position. The second compensation pattern 540 is disposed between the plurality of gate lines GL and between the gate low voltage line VGLL and the gate high voltage line VGHL, and may have a constant width.

[0209] The length of the clock wiring CLKL arranged in the fourth region A4 may be the same as the length of the clock wiring CLKL arranged in the third region A3. For example, the clock wiring CLKL arranged in the fourth region A4 adjacent to the notch region NTA may have a zigzag shape. For example, a portion of the clock wiring CLKL arranged in the fourth region A4 that overlaps with the second compensation pattern 540 may have a zigzag shape. Therefore, even if the width of the fourth region A4 is smaller than the width of the third region A3, the total length of the clock wiring CLKL arranged in the fourth region A4 may be the same as the total length of the clock wiring CLKL arranged in the third region A3.

[0210] 17, for ease of explanation, only the substrate 110, buffer layer 111, gate insulating layer 112, first interlayer insulating layer 113, second compensation pattern 540, second interlayer insulating layer 114, clock line CLKL, intermediate electrode CEE, first planarization layer 115, and third compensation pattern 550 are shown. In the following, the remaining configurations are the same as those in FIG. 4 except for the second compensation pattern 540, clock line CLKL, intermediate electrode CEE, and third compensation pattern 550, and therefore detailed description thereof will be omitted.

[0211] Referring to FIG. 17, a second compensation pattern 540 may be disposed between the first interlayer insulating layer 113 and the second interlayer insulating layer 114.

[0212] The second compensation pattern 540 may be formed in the same layer and made of the same material as the second capacitor electrode Cst2. For example, the second compensation pattern 540 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0213] A clock line CLKL may be disposed on the second interlayer insulating layer 114.

[0214] The clock line CLKL may be disposed on the second interlayer insulating layer 114 to overlap the second compensation pattern 540. The clock line CLKL may be formed in the same layer and made of the same material as the first source electrode SE1 and the first drain electrode DE1 of the first transistor T1. For example, the clock line CLKL may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0215] An intermediate electrode CEE may be disposed on the second interlayer insulating layer 114 .

[0216] The intermediate electrode CEE may be disposed in the same layer and made of the same material as the clock line CLKL. The intermediate electrode CEE may be electrically connected to the second compensation pattern 540 through a contact hole formed in the second interlayer insulating layer 114.

[0217] A third compensation pattern 550 may be disposed on the first planarization layer 115 .

[0218] The third compensation pattern 550 may overlap the clock line CLKL. The third compensation pattern 550 may be electrically connected to the intermediate electrode CEE through a contact hole formed in the first planarization layer 115. The third compensation pattern 550 may be disposed in the same layer as the connecting electrode CE and may be made of the same material. For example, the third compensation pattern 550 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0219] That is, the clock line CLKL overlaps the second compensation pattern 540 and the third compensation pattern 550, and the third compensation pattern 550, to which a constant voltage is applied, may be electrically connected to the second compensation pattern 540 through the contact hole and the intermediate electrode CEE. Thus, a capacitor is formed between the clock line CLKL and the second compensation pattern 540, and a capacitor is formed between the clock line CLKL and the third compensation pattern 550, thereby delaying the clock signal applied to the clock line CLKL.

[0220] Therefore, in a display device 500 according to another embodiment of the present specification, a first compensation pattern 230 is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second region A2 so as to overlap with the gate line GL, and a capacitor is formed between the gate line GL and the first compensation pattern 230, thereby compensating for the RC delay of the gate signals output from the plurality of gate blocks GB1 and GB2 disposed in the second region A2. Therefore, in the display device 500 according to another embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure is compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0221] In a display device 500 according to another embodiment of the present specification, a plurality of gate blocks GB1 and GB2, into which a gate driver is divided, are distributed in the display area AA, and a first compensation pattern 230 for compensating for an RC delay deviation is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second area A2, thereby minimizing the area of ​​the non-display area NA. Therefore, in a display device 500 according to another embodiment of the present specification, the gate driver and the first compensation pattern 230 are disposed within the display area, thereby minimizing the bezel area.

[0222] In the conventional display device, the substrate is a rectangular substrate without any irregular structure on one side, and the same clock signal is provided to the gate driver disposed at the bottom of the display area. However, in the case of an irregular display device in which one or more of the four sides of the substrate that is not a rectangular substrate have an irregular structure, the time at which the clock signal is provided to the gate driver disposed at the bottom of the third region A3, which is an area without an irregular structure, differs from the time at which the clock signal is provided to the gate driver disposed at the bottom of the fourth region A4, which is an area with an irregular structure, resulting in uneven brightness.

[0223] Therefore, in a display device 500 according to another embodiment of the present disclosure, a second compensation pattern 540 and a third compensation pattern 550 are disposed to overlap a clock line CLKL disposed in at least one gate block GB1-1 among the plurality of gate blocks GB disposed in the fourth region A4. A capacitor is formed between the clock line CLKL and the second compensation pattern 540, and a capacitor is formed between the clock line CLKL and the third compensation pattern 550, thereby compensating for the RC delay of the clock signal transmitted through the clock line CLKL disposed in the fourth region A4. That is, the clock signals transmitted through the clock line CLKL disposed in the fourth region A4 and the clock line CLKL disposed in the third region A3 can be transmitted to the respective gate drivers in the same manner. Therefore, in the display device 500 according to another embodiment of the present disclosure, the RC delay difference between the clock signals in different regions is compensated for to be uniform, thereby reducing brightness unevenness and improving display quality.

[0224] FIG. 18 is a cross-sectional view of one of the gate blocks of a display device according to still another embodiment of the present disclosure.

[0225] 18 is a cross-sectional view of the 1-1st gate block GB1-1 among the gate blocks GB of a display device 600 according to still another embodiment of the present specification. FIG. 16 is a cross-sectional view taken at the same position as FIG.

[0226] 18, for ease of explanation, only shows the substrate 410, the first buffer layer 411, the first gate insulating layer 412, the first interlayer insulating layer 413, the second buffer layer 414, the second gate insulating layer 415, the second compensation pattern 640, the second interlayer insulating layer 416, the clock line CLKL, the intermediate electrode CEE, the first planarization layer 417, and the third compensation pattern 650. Since the remaining configuration is the same as that of FIG. 11 except for the second compensation pattern 640, the clock line CLKL, the intermediate electrode CEE, and the third compensation pattern 650, detailed explanations will be omitted below.

[0227] Referring to FIG. 18, a second compensation pattern 640 may be disposed on the second gate insulating layer 415 .

[0228] The second compensation pattern 640 may be disposed in the same layer as the second gate electrode GE2 of the second transistor T2 and may be made of the same material. For example, the second compensation pattern 640 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0229] On the second interlayer insulating layer 416, the clock line CLKL and the intermediate electrode CEE can be disposed.

[0230] The clock line CLKL may be disposed on the second interlayer insulating layer 416 to overlap the second compensation pattern 640. The clock line CLKL may overlap the second compensation pattern 640 to form a capacitor between the clock line CLKL and the second compensation pattern 640. The clock line CLKL may be disposed in the same layer as the first source electrode SE1 and the first drain electrode DE1 of the first transistor T1 and the second source electrode SE2 and the second drain electrode DE2 of the second transistor T2 and may be made of the same material. For example, the clock line CLKL may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0231] The intermediate electrode CEE may be disposed in the same layer as the clock line CLKL and may be made of the same material. The intermediate electrode CEE may be electrically connected to the second compensation pattern 640 through a contact hole formed in the second interlayer insulating layer 416.

[0232] A third compensation pattern 650 may be disposed on the first planarization layer 417 .

[0233] The third compensation pattern 650 may overlap the clock line CLKL. The third compensation pattern 650 may be electrically connected to the intermediate electrode CEE through a contact hole formed in the first planarization layer 417. The third compensation pattern 650 may be disposed in the same layer as the connecting electrode CE and may be made of the same material. For example, the third compensation pattern 650 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0234] That is, the clock line CLKL overlaps the second compensation pattern 640 and the third compensation pattern 650, and the third compensation pattern 650, to which a constant voltage is applied, may be electrically connected to the second compensation pattern 640 through the contact hole and the intermediate electrode CEE. Thus, a capacitor is formed between the clock line CLKL and the second compensation pattern 640, and a capacitor is formed between the clock line CLKL and the third compensation pattern 650, thereby delaying the clock signal applied through the clock line CLKL.

[0235] Therefore, in a display device 600 according to another embodiment of the present specification, a first compensation pattern 230 is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second region A2 so as to overlap with the gate line GL, and a capacitor is formed between the gate line GL and the first compensation pattern 230, thereby compensating for the RC delay of the gate signals output from the plurality of gate blocks GB1 and GB2 disposed in the second region A2. Therefore, in the display device 600 according to another embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure is compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0236] In a display device 600 according to another embodiment of the present specification, a plurality of gate blocks GB1 and GB2, into which a gate driver is divided, are distributed in the display area AA, and a first compensation pattern 230 for compensating for an RC delay deviation is disposed in at least one gate block GB2 of the plurality of gate blocks GB1 and GB2 disposed in the second area A2, thereby minimizing the area of ​​the non-display area NA. Therefore, in the display device 600 according to another embodiment of the present specification, the gate driver and the first compensation pattern 230 are disposed within the display area, thereby minimizing the bezel area.

[0237] In display device 600 according to another embodiment of the present disclosure, second compensation pattern 640 and third compensation pattern 650 are arranged to overlap with clock line CLKL arranged in at least one gate block GB1-1 among the plurality of gate blocks GB arranged in the fourth region A4. A capacitor is formed between clock line CLKL and second compensation pattern 640, and a capacitor is formed between clock line CLKL and third compensation pattern 650, thereby compensating for the RC delay of the clock signal transmitted through clock line CLKL arranged in the fourth region A4. That is, clock signals transmitted through clock line CLKL arranged in the fourth region A4 and clock line CLKL arranged in the third region A3 can be transmitted to the respective gate drivers in the same manner. Therefore, in display device 600 according to another embodiment of the present disclosure, the irregular structure compensates for the RC delay difference of the clock signal depending on the region to be uniform, thereby reducing brightness unevenness and improving display quality.

Since the remaining configuration is the same as that of FIG. 16 except for the fourth compensation pattern 760, detailed explanations will be omitted below.

[0241] Referring to FIG. 19, a fourth compensation pattern 760 may be disposed between the first interlayer insulating layer 413 and the second compensation pattern 640.

[0242] The fourth compensation pattern 760 may be disposed between the first interlayer insulating layer 413 and the second buffer layer 414. The fourth compensation pattern 760 may be disposed to overlap the second compensation pattern 640. The fourth compensation pattern 760 may be electrically connected to the second compensation pattern 640 through a contact hole formed in the second buffer layer 414.

[0243] The fourth compensation pattern 760 may be disposed in the same layer as the second capacitor electrode Cst2 of the storage capacitor Cst and may be made of the same material. For example, the second capacitor electrode Cst2 may be formed as a single layer or multiple layers made of any one of molybdenum (Mo), copper (Cu), titanium (Ti), aluminum (Al), chromium (Cr), gold (Au), nickel (Ni), and neodymium (Nd), or an alloy thereof.

[0244] That is, the clock line CLKL overlaps with the second compensation pattern 640, the third compensation pattern 650, and the fourth compensation pattern 760, and the third compensation pattern 650, to which a constant voltage is applied, may be electrically connected to the fourth compensation pattern 760 through the contact hole, the intermediate electrode CEE, and the second compensation pattern 640.

Therefore, in the display device 700 according to another embodiment of the present specification, the RC delay of the gate signals changed due to the irregular structure is compensated to be the same as that in a region without the irregular structure, thereby reducing brightness unevenness and improving display quality.

[0246] In a display device 700 according to another embodiment of the present specification, a plurality of gate blocks GB1, GB2 into which a gate driver is divided are distributed in the display area AA, and a first compensation pattern 230 for compensating for an RC delay deviation is disposed in at least one gate block GB2 of the plurality of gate blocks GB1, GB2 disposed in the second area A2, thereby minimizing the area of ​​the non-display area NA.
