[0002] The present disclosure relates to a display device. Background Art
[0003] Due to the growth and continued development of information technology, the demand for display devices for displaying images has been increasing. For example, display devices have been applied to various electronic devices such as smartphones, digital cameras, notebook computers, navigation devices, and smart televisions (TVs). Examples of display devices include flat panel display devices such as liquid crystal display (LCD) devices, field emission display (FED) devices, and organic light emitting diode (OLED) display devices.
[0004] A typical display device may include a display panel including pixels for displaying an image. The display panel may include a display area in which the pixels are formed and a non-display area occupying or corresponding to the remainder of the display panel. A pad connected to a flexible film or circuit board may be formed on one side of the display panel. Therefore, the portion of the non-display area located on one side of the display device may be larger than the portion of the non-display area located on the other side of the display device.
[0005] It will be understood that this background section is intended, in part, to provide a useful context for understanding the technology. However, this background section may also include ideas, concepts, or understandings that are not known or understood by those skilled in the relevant art before the corresponding effective filing date of the subject matter disclosed herein. Summary of the Invention
[0006] The embodiment may provide a display device capable of minimizing a difference in size between portions of a non-display area located on both sides of the display device.

The fan-out line may be disposed in one of the first source metal layer and the second source metal layer located in the bending region, the second source metal layer being disposed on the first source metal layer.
[0024] The scan driver may be disposed in the pad region of the display panel.
[0025] The pad region may include a bending region, a first sub-pad region in which the display driver may be disposed, and a second sub-pad region disposed between the bending region and the first sub-pad region and including a scan driver.

[0031] According to an embodiment, a display device may include: a display panel including a display area, a non-display area provided at a periphery of the display area, and a pad area provided at a side of the non-display area; data lines provided in the display area of the display panel along a second direction intersecting with a first direction; and first connection lines provided in the display area of the display panel and including a first sub-connection line provided along the first direction and a second sub-connection line provided along the second direction. A first data line of the data lines may be connected to the second sub-connection line.
[0032] The pad region may protrude from the non-display region in the first direction.
[0033] A length of the display panel in the first direction may be smaller than a length of the display panel in the second direction.

The second sub-link line may overlap the second power supply line.
[0038] According to an embodiment, when the pad area protrudes from the non-display area in a direction parallel to the short side of the display panel, the width of the pad area can be greater than when the pad area protrudes from the non-display area in a direction parallel to the long side of the display panel. Therefore, it can be beneficial to design and / or arrange the fan-out line connecting the display area and the pad area. Therefore, the difference between the width of the portion of the non-display area located on the outer left side of the display area and the width of the portion of the non-display area located on the outer right side of the display area can be minimized.
[0039] The connection wiring may overlap the power line in the thickness direction of the display panel. The presence of the power line can prevent the formation of parasitic capacitance between the connection line and the switching transistor. In other words, the power line can prevent coupling between the connection line and the switching transistor. This can reduce or minimize the effect of the data voltage applied to the connection line on the switching transistor.
[0040] In addition, the scan driver can be provided in the pad area rather than the non-display area. Therefore, the difference between the width of the portion of the non-display area located on the outer left side of the display area and the width of the portion of the non-display area located on the outer right side of the display area can be minimized.

[0069] Now, the embodiments will be described more fully below with reference to the accompanying drawings. However, the embodiments may be provided in different forms and should not be construed as limiting. Throughout this disclosure, the same reference numerals represent the same components. In the accompanying drawings, the thickness of layers and regions may be exaggerated for clarity.
[0070] It will also be understood that when a layer is referred to as being “on” another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. In contrast, when an element is referred to as being “directly on” another element, there may be no intervening elements present.
[0071] In addition, in the specification, the phrase "in a plan view" refers to when the object portion is viewed from above, and the phrase "in a cross-sectional view" refers to when a cross-section taken by vertically cutting the object portion is viewed from the side. In addition, the term "overlapping" or "overlapping" means that the first object can be above or below the second object, and vice versa. The term "facing" or "facing..." means that the first object can be directly or indirectly opposite to the second object. In the case where a third object is interposed between the first and second objects, the first and second objects can be understood as being indirectly opposite to each other, although still facing each other.
[0072] For ease of description, spatially relative terms such as "below," "beneath," "below," "above," or "on" may be used herein to describe the relationship between one element or component and another element or component as shown in the accompanying drawings. It will be understood that the spatially relative terms are intended to cover different orientations of the device in use or operation in addition to the orientations depicted in the accompanying drawings. For example, where the device shown in the accompanying drawings is flipped over, a device that is "below" or "beneath" another device may be "above" the other device. Thus, the exemplary term "below" can include both a lower position and an upper position. Devices may also be positioned in other orientations, and therefore, the spatially relative terms may be interpreted differently depending on the orientation.
[0073] Throughout this specification, when an element is referred to as being "connected" to another element, the element may be "directly connected" to the other element, or "electrically connected" to the other element, with one or more intermediate elements interposed therebetween. It will be further understood that when the terms "comprises," "comprising," "containing," and / or "having" are used in this specification, this may indicate the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of other features, integers, steps, operations, elements, components, and / or any combination thereof.
[0074] It will be understood that although the terms "first," "second," or "third," etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element or to facilitate description and explanation thereof. For example, when discussing a "first element" in the specification, it may be referred to as a "second element" or a "third element," and the "second element" and "third element" may be named in a similar manner without departing from the teachings herein.
[0075] As used herein, "about" or "approximately" includes the stated value and means within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art, taking into account the measurements in question and errors associated with the measurement of the particular quantity (i.e., limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5% of the stated value.
[0076] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. It will be further understood that, unless expressly defined in this specification, terms such as those defined in general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense.
[0077] Figure 1 is a perspective view of a display device 10 according to an embodiment.
[0078] Reference Figures 1 to 4 The display device 10 for displaying images such as moving images and / or still images can be used not only in portable electronic devices such as mobile phones, smart phones, tablet personal computers (PCs), smart watches, watch phones, mobile communication terminals, electronic notebooks, electronic books, portable multimedia players (PMPs), navigation devices, or ultra-mobile personal computers (UMPCs), but can also be used in various other products such as televisions (TVs), notebook computers, monitors, billboards, or Internet of Things (IoT) devices. The display device 10 can be an organic light emitting diode (OLED) display device, a liquid crystal display (LCD) device, a plasma display device, a field emission display (FED) device, an electrophoretic display (EPD) device, an electrowetting display device, a quantum dot light emitting diode (QLED) display device, and / or a micro light emitting diode (mLED) display device. The display device 10 will be described below as an OLED display device, but the embodiment is not limited thereto.
[0079] The display device 10 may include a display panel 100 , a display driver 200 , and a circuit board 300 .
[0080] As used herein, the terms "above," "top," and "top surface" may refer to an upper direction from the display panel 100, that is, the Z-axis direction, and as used herein, the terms "below," "bottom," and "bottom surface" may refer to a downward direction from the display panel 100, that is, the opposite direction of the Z-axis direction. In addition, as used herein, the terms "left," "right," "up," and "down" may refer to respective directions of the display panel 100 as viewed from above. For example, the term "left" may refer to the opposite direction of the X-axis direction, the term "right" may refer to the X-axis direction, the term "up" may refer to the Y-axis direction, and the term "down" may refer to the opposite direction of the Y-axis direction.
[0081] The display panel 100 may be formed in a rectangular shape in a plan view having a pair of short sides extending in a first direction (or X-axis direction) and a pair of long sides extending in a second direction (or Y-direction) intersecting the first direction (or X-axis direction). The corners where the short and long sides of the display panel 100 intersect may be rounded to have a predetermined curvature or may be right angles. The shape of the display device 10 is not particularly limited, and the display device 10 may be formed in various other polygonal shapes or in a circular or elliptical shape.
[0082] The display panel 100 may include a display area DA, a non-display area NDA, and a pad area PA.
[0083] The display area DA may be an area in which sub-pixels may be arranged to display an image. The non-display area NDA may be an area located outside the display area DA and may not display an image. The non-display area NDA may be arranged to surround the display area DA. The pad area PA may be an area to which the display driver 200 and the circuit board 300 may be attached. The pad area PA may not display an image. The pad area PA may protrude from the non-display area NDA in a first direction (or X-axis direction). The length of the pad area PA in the first direction (or X-axis direction) may be smaller than the length of the display area DA in the first direction (or X-axis direction). The length of the pad area PA in the second direction (or Y-axis direction) may be smaller than the length of the display area DA in the second direction (or Y-axis direction). The display driver 200 and the circuit board 300 may be arranged in the pad area PA.
[0084] The display driver 200 can output signals and voltages for driving the display panel 100. For example, the display driver 200 can output data voltages to data lines. In addition, the display driver 200 can output power voltages to power lines and can output scan control signals to a scan driver. The display driver 200 can be formed as an integrated circuit (IC) and can be provided on the display panel 100 in the first sub-pad area PDA by, for example, chip-on-glass (COG) or chip-on-plastic (COP) or by ultrasonic welding, but the embodiment is not limited thereto. For example, the display driver 200 can be provided on the circuit board 300.
[0085] The circuit board 300 may be attached to the pads via, for example, an anisotropic conductive film. Thus, the conductive lines of the circuit board 300 may be electrically connected to the pads of the display panel 100. The circuit board 300 may be a flexible film such as a flexible printed circuit board, a printed circuit board, or a chip-on-film.
[0086] Figures 2 to 4 yes Figure 1 10 is a side view of the display device 10.
[0087] Reference Figures 2 to 4 The pad area PA may include a bending area BA and a first sub-pad area PDA. The first sub-pad area PDA may be disposed on one side of the bending area BA, and the non-display area NDA may be disposed on the other side of the bending area BA. For example, the first sub-pad area PDA may be disposed on the right side of the bending area BA, and the non-display area NDA may be disposed on the left side of the bending area BA. The display driver 200 and the circuit board 300 may be disposed in the first sub-pad area PDA of the display panel 100.
[0088] The display panel 100 may be formed as a flexible display panel and thus may be bendable in the bending area BA. Figure 2 , before the display panel 100 is bent in the bending area BA, the first surface of the first subpad area PDA of the display panel 100 may face upward. Figure 3 When the display panel 100 is bent in the bending area BA and / or after the display panel 100 is bent in the bending area BA, the first surface of the first sub-pad area PDA of the display panel 100 may face downward. When the display panel 100 is bent in the bending area BA and / or after the display panel 100 is bent in the bending area BA, the first sub-pad area PDA of the display panel 100 may be disposed below the display area DA. When the display panel 100 is bent in the bending area BA and / or after the display panel 100 is bent in the bending area BA, the first sub-pad area PDA of the display panel 100 may overlap with the display area DA in the thickness direction of the display panel 100 (i.e., in the Z-axis direction).
[0089] The display panel 100 may be curved at the boundary between the non-display area NDA and the pad area PA, but the embodiment is not limited thereto. In other embodiments, the display panel 100 may not be curved at the boundary between the non-display area NDA and the pad area PA. For example, the display panel 100 may be curved at a position away from the boundary between the non-display area NDA and the pad area PA. Such a distance may be, for example, in the range of approximately 200 μm to 300 μm.
[0090] Reference Figure 3 The display panel 100 may include a flat portion FA, a first curved portion CA1, and a second curved portion CA2. The first curved portion CA1 may be curved from a first side of the flat portion FA with a first curvature. The second curved portion CA2 may be curved from a second side of the flat portion FA with a second curvature. For example, the first and second sides of the flat portion FA may be the left and right sides of the flat portion FA, respectively. The display area DA of the display panel 100 may be provided not only in the flat portion FA but also in the first and second curved portions CA1 and CA2. Therefore, images may be displayed not only in the flat portion FA but also in the first and second curved portions CA1 and CA2.
[0091] Figure 3 The first curvature of the first curved portion CA1 and the second curvature of the second curved portion CA2 are shown to be substantially the same, but the embodiment is not limited thereto. In other embodiments, the first curvature of the first curved portion CA1 and the second curvature of the second curved portion CA2 may be different from each other. In another embodiment, each of the first curved portion CA1 and the second curved portion CA2 may have a variable curvature rather than a uniform curvature.
[0092] The display panel 100 may include only one of the first and second curved portions CA1 and CA2. In another example, the display panel 100 may not include the first and second curved portions CA1 and CA2, but may include only the flat portion FA.
[0093] Reference Figure 4 The display panel 100 may include a first curved portion CA1, a second curved portion CA2, and a third curved portion CA3. The first curved portion CA1 may be bent from a first side of the third curved portion CA3 at a first curvature. The second curved portion CA2 may be bent from a second side of the third curved portion CA3 at a second curvature. The third curved portion CA3 may be bent at a third curvature. For example, the first side and the second side of the third curved portion CA3 may be the left side and the right side of the third curved portion CA3, respectively.
[0094] The display area DA of the display panel 100 may be disposed in the first, second, and third curved portions CA1, CA2, and CA3, and thus, an image may be displayed in the first, second, and third curved portions CA1, CA2, and CA3.
[0095] Figure 4 The first curvature of the first curved portion CA1 and the second curvature of the second curved portion CA2 are shown to be substantially the same, but the embodiment is not limited thereto. In other embodiments, the first curvature of the first curved portion CA1 and the second curvature of the second curved portion CA2 may be different from each other. In another example, each of the first curved portion CA1 and the second curved portion CA2 may have a variable curvature rather than a uniform curvature. The first curvature of the first curved portion CA1 and the second curvature of the second curved portion CA2 may be greater than the third curvature of the third curved portion CA3.
[0096] The display panel 100 may include only one of the first and second curved portions CA1 and CA2. In another example, the display panel 100 may not include the first and second curved portions CA1 and CA2, but may include only the third curved portion CA3.
[0097] The panel cover bottom 101 may be disposed under the display panel 100. The panel cover bottom 101 may be attached to the bottom surface of the display panel 100 via an adhesive member 102, and the adhesive member may be a pressure sensitive adhesive (PSA).
[0098] The panel bottom cover 101 may include a light absorbing member for absorbing light incident from the outside, a buffering member for absorbing shock from the outside, and a heat dissipating member for effectively releasing heat from the display panel 100 .
[0099] A light absorbing member may be provided below the display panel 100. The light absorbing member may block transmission of light, thereby preventing elements disposed therebelow (such as, for example, the circuit board 300) from becoming visible from above the display panel 100. The light absorbing member may include a light absorbing material such as a black pigment or a black dye.
[0100] A buffer member may be provided below the light absorbing member. The buffer member may absorb external shocks, thereby preventing damage to the display panel 100. The buffer member may be formed as a single-layer film or a multi-layer film. For example, the buffer member may be formed from a polymer resin such as polyurethane, polycarbonate, polypropylene, polyethylene, or a combination thereof. The buffer member may include an elastic material such as rubber, urethane, a sponge made of foamed acrylic material, or a combination thereof. The buffer member may be a cushion layer.
[0101] The heat dissipation member may be disposed below the buffer member. The heat dissipation member may include a first heat dissipation layer and a second heat dissipation layer, the first heat dissipation layer may include graphite or carbon nanotubes, and the second heat dissipation layer may be formed as a metal thin film capable of blocking electromagnetic waves and having excellent thermal conductivity, such as, for example, a metal thin film formed of copper (Cu), nickel (Ni), ferrite, silver (Ag), or a combination thereof.
[0102] In order to make the display panel 100 easily bendable, for example Figure 3 As shown in , the panel bottom cover 101 may not be provided in the curved area BA of the display panel 100. A portion of the panel bottom cover 101 in the flat portion FA of the display panel 100 and a portion of the panel bottom cover 101 in the first sub-pad area PDA of the display panel 100 may be attached together by an adhesive member 102. The first sub-pad area PDA of the display panel 100 may be fixed to the bottom of the flat portion FA of the display panel 100. The adhesive member 102 may be a PSA. In another example, a portion of the panel bottom cover 101 in the first curved portion CA1 of the display panel 100 and a portion of the panel bottom cover 101 in the first sub-pad area PDA of the display panel 100 may be attached together by an adhesive member 102. The first sub-pad area PDA of the display panel 100 may be fixed to the bottom of the first curved portion CA1 of the display panel 100.
[0103] Figure 5 It shows Figure 1 A plan view of a display panel, a display driver, and a scan driver of a display device.
[0104] Reference Figure 5 The display panel 100 may include a display area DA and a non-display area NDA. The display area DA includes sub-pixels and displays an image. The non-display area NDA may be an area located outside the display area DA. Sub-pixels, scan lines, data lines DL, power lines, and connection lines CL may be arranged in the display area DA. The scan driver 400 and the fan-out lines FL may be arranged in the non-display area NDA. For the purpose of convenience of description, Figure 5 The connection lines CL, data lines DL and fan-out lines FL are shown. Figure 5 Sub-pixels, scan lines, and power supply lines are not shown.
[0105] In the display area DA, the connection line CL may extend in a first direction (or X-axis direction), and the data line DL may extend in a second direction (or Y-axis direction). The scan line may be arranged parallel to the connection line CL. For example, the scan line may extend in the first direction (or X-axis direction).
[0106] The power lines may include a first power line and a second power line, a first power voltage may be applied to the first power line, and a second power voltage may be applied to the second power line. The first power voltage may be an initialization voltage for initializing the sub-pixel, and the second power voltage may be a pixel drive voltage for driving the sub-pixel. The second power voltage may be higher than the first power voltage. The first power line may be arranged parallel to the connection line CL. For example, the first power line may extend in a first direction (or an X-axis direction). The second power line may be arranged parallel to the data line DL. For example, the second power line may extend in a second direction (or a Y-axis direction).
[0107] The connection lines CL may be connected to the data lines DL through the connection holes CT. The data lines DL may be connected to the connection lines CL through the connection holes CT. The connection lines CL may be connected to the data lines DL. For example, each connection line CL may be connected to a corresponding one of the data lines DL.
[0108] The pad area PA includes a bending area BA and a first sub-pad area PDA, and the display driver 200 and the pad PAD can be disposed in the first sub-pad area PDA. The display driver 200 can be formed as an IC and can be disposed on the display panel 100 in the first sub-pad area PDA, for example, in a COG or COP manner or by ultrasonic welding. The circuit board 300 can be attached to the pad PAD, for example, via an anisotropic conductive film. Thus, the conductive lines of the circuit board 300 can be electrically connected to the pad PAD.
[0109] The fan-out lines FL may be disposed in the bending area BA and the first sub-pad area PDA. The fan-out lines FL may include a first fan-out line FL1 and a second fan-out line FL2. The first fan-out line FL1 may be disposed in the first sub-pad area PDA and may be connected to the display driver 200. In a portion of the first sub-pad area PDA adjacent to the bending area BA, the first fan-out line FL1 may be connected to the second fan-out line FL2 via a first wiring connection hole FCT1. The second fan-out line FL2 may be disposed in the bending area BA. In the non-display area NDA, the second fan-out line FL2 may be connected to the connection line CL via a second wiring connection hole FCT2.
[0110] Figure 5 It is shown that the second wiring connection hole FCT2 may be provided between the scan driver 400 and the pad area PA, but the embodiment is not limited thereto. In other embodiments, the second wiring connection hole FCT2 may be provided between the scan driver 400 and the display area DA.
[0111] The scan driver 400 may be disposed in a portion of the non-display area NDA located at an outer right side of the display area DA. The scan driver 400 may be disposed between the display area DA and the bending area BA of the pad area PA.
[0112] The scan driver 440 may include thin film transistors (TFTs). The TFTs of the scan driver 440 may be formed in the same layer as the TFTs of the sub-pixels in the display area DA.
[0113] according to Figure 5 In an embodiment, the pad area PA, in which the display driver 200 may be provided, protrudes from the non-display area NDA in a first direction (or X-axis direction), the first direction (or X-axis direction) intersecting the direction in which the data lines DL extend (i.e., the second direction (or Y-axis direction). Therefore, the data lines DL extending in the second direction (or Y-axis direction) may receive data voltages from the display driver 200 via the connection lines CL extending in the first direction (or X-axis direction).
[0114] and Figure 5 Compared to the embodiment of the present invention, the embodiment may include a pad area PA protruding from the non-display area NDA in the second direction (or Y-axis direction), in which the display driver 200 may be disposed. In the embodiment in which the pad area PA protrudes from the non-display area NDA in the second direction (or Y-axis direction), the length of the pad area PA in the first direction (or X-axis direction) needs to be less than the length of the display area DA in the first direction (or X-axis direction). Therefore, due to the presence of the fan-out line FL connecting the display area DA and the pad area PA, a difference inevitably occurs between the width of the portion of the non-display area NDA located on the outer upper side of the display area DA and the width of the portion of the non-display area NDA located on the outer lower side of the display area DA.
[0115] Return to reference Figure 5, the pad area PA may protrude from the non-display area NDA in a first direction (or X-axis direction), and the length of the pad area PA in a second direction (or Y-axis direction) may be less than the length of the display area DA in the second direction (or Y-axis direction). When the pad area PA protrudes from the non-display area NDA in the first direction (or X-axis direction), the length of the pad area PA in the second direction (or Y-axis direction) (i.e., the width of the pad area PA) may be greater than the length of the pad area PA in the first direction (or X-axis direction) (i.e., the width of the pad area PA) when the pad area PA protrudes from the non-display area NDA in the second direction (or Y-axis direction). Therefore, the design and / or arrangement of the fan-out line FL connecting the display area DA and the pad area PA can be facilitated. Therefore, the difference between the width of the portion of the non-display area NDA located on the outer left side of the display area DA and the width of the portion of the non-display area NDA located on the outer right side of the display area DA can be minimized.
[0116] Figure 6 It shows Figure 5 Specifically, Figure 6 Illustrated are first, second, and third data lines DL1, DL2, and DL3, and first, second, and third connection lines CL1, CL2, and CL3 that may be connected to the first, second, and third data lines DL1, DL2, and DL3, respectively.
[0117] Reference Figure 6 , the first connection line CL1, the second connection line CL2, and the third connection line CL3 can extend in the first direction (or the X-axis direction). The first data line DL1, the second data line DL2, and the third data line DL3 can extend in the second direction (or the Y-axis direction). The first power line VIL, to which the first power supply voltage can be applied, can extend in the first direction (or the X-axis direction). The second power line VDDL, to which the second power supply voltage can be applied, can extend in the second direction (or the Y-axis direction). The first power supply voltage can be an initialization voltage for initializing the sub-pixel, and the second power supply voltage can be a pixel driving voltage for driving the sub-pixel. The second power supply voltage can be higher than the first power supply voltage.
[0118] The first, second, and third connection lines CL1, CL2, and CL3 and the first power line VIL extending in the first direction (or X-axis direction) may intersect the first, second, and third data lines DL1, DL2, and DL3 and the second power line VDDL extending in the second direction (or Y-axis direction).
[0119] The first connection line CL1, the second connection line CL2, and the third connection line CL3 may overlap with the first power line VIL in the thickness direction of the display panel 100 (i.e., in the third direction (or Z-axis direction)). The first connection line CL1 may be connected to the first data line DL1 via a first connection hole CT1, which may be formed in the overlapping region of the first data line DL1 and the first power line VIL. The second connection line CL2 may be connected to the second data line DL2 via a second connection hole CT2, which may be formed in the overlapping region of the second data line DL2 and the first power line VIL. The third connection line CL3 may be connected to the third data line DL3 via a third connection hole CT3, which may be formed in the overlapping region of the third data line DL3 and the first power line VIL.
[0120] The first dummy pattern DM1 may be spaced apart from the first connection line CL1 in the first direction (or X-axis direction) and may overlap with the first power line VIL in the third direction (or Z-axis direction), with the first power line VIL overlapping the first connection line CL1. The second dummy pattern DM2 may be spaced apart from the second connection line CL2 in the first direction (or X-axis direction) and may overlap with the first power line VIL in the third direction (or Z-axis direction), with the first power line VIL overlapping the second connection line CL2. The third dummy pattern DM3 may be spaced apart from the third connection line CL3 in the first direction (or X-axis direction) and may overlap with the first power line VIL in the third direction (or Z-axis direction), with the first power line VIL overlapping the third connection line CL3. The first, second, and third dummy patterns DM1, DM2, and DM3 may be formed as islands and may be electrically floating. That is, no voltage is applied to the first, second, and third dummy patterns DM1, DM2, and DM3.
[0121] In the case where the first, second, and third dummy patterns DM1, DM2, and DM3 may not be formed, the amount of external light reflected in the region where the first, second, and third connection lines CL1, CL2, and CL3 may be provided is different from the amount of external light reflected in the region where the first, second, and third connection lines CL1, CL2, and CL3 may not be provided, and thus the connection lines CL1, CL2, and CL3 may be visible to the user. However, if the first, second, and third dummy patterns DM1, DM2, and DM3 may be provided in the region where the first, second, and third connection lines CL1, CL2, and CL3 may not be provided, the amount of external light reflected in the region where the first, second, and third connection lines CL1, CL2, and CL3 may be provided is not significantly different from the amount of external light reflected in the region where the first, second, and third connection lines CL1, CL2, and CL3 may not be provided, and thus the first, second, and third connection lines CL1, CL2, and CL3 may be prevented from becoming visible to the user.
[0122] according to Figure 6 In an embodiment of the present invention, the first connection line CL1, the second connection line CL2, and the third connection line CL3 may be connected to the first data line DL1, the second data line DL2, and the third data line DL3, respectively, through the first connection hole CT1, the second connection hole CT2, and the third connection hole CT3. Therefore, the first data line DL1, the second data line DL2, and the third data line DL3 extending in the second direction (or the Y-axis direction) may receive a data voltage from the display driver 200 via the first connection line CL1, the second connection line CL2, and the third connection line CL3 extending in the first direction (or the X-axis direction).

[0170] In a top emission structure that emits light in a direction from the organic light-emitting layer 172 to the second electrode 173, the first electrode 171 can be formed of a metal material with high reflectivity, such as a stack of Al and Ti (e.g., Ti / Al / Ti), a stack of Al and indium tin oxide (ITO) (e.g., ITO / Al / ITO), a silver-palladium-copper (APC) alloy, or a stack of an APC alloy and ITO (e.g., ITO / APC / ITO).
[0171] The pixel defining film 190 may be formed to define the first electrode 171 above the second planarization film 180, thereby defining the emission area EA. The pixel defining film 190 may be formed to cover the edge of the first electrode 171.

[0175] In a top emission structure, the second electrode 173 may be formed of a transparent conductive oxide (TCO) material such as ITO or IZO, or a semi-transparent metal material such as magnesium (Mg), Ag, or an alloy of Mg and Ag. When the second electrode 173 is formed of a semi-transparent metal material, the emission efficiency of the light-emitting element layer EML may be improved due to a microcavity effect.

Due to the presence of the first power line VIL, parasitic capacitances may be prevented from being formed between the first connection line CL1 and the second electrode D1-1 of the (1-1)th transistor ST1-1, between the first connection line CL1 and the first electrode S1-2 of the (1-2)th transistor ST1-2, and between the first connection line CL1 and the second electrode D5 of the fifth transistor ST5. That is, due to the presence of the first power line VIL, coupling may be prevented from being generated between the first connection line CL1 and the second electrode D1-1 of the (1-1)th transistor ST1-1, between the first connection line CL1 and the first electrode S1-2 of the (1-2)th transistor ST1-2, and between the first connection line CL1 and the second electrode D5 of the fifth transistor ST5.

[0191] Reference Figure 12 If the scan driver 400 is disposed at the outer right side of the display area DA, the complexity of wiring in the portion of the non-display area NDA located at the outer right side of the display area DA may be excessively high due to the presence of the fan-out lines FL and the scan driver 400. Conversely, if the scan driver 400 is disposed at the outer left side of the display area DA, the complexity of wiring in the portion of the non-display area NDA located at the outer right side of the display area DA can be reduced due to the presence of the scan driver 400.

[0197] exist Figure 14 In the embodiment of the present invention, the scan driver 400 may be disposed in the pad area PA instead of in the non-display area NDA.
[0198] Reference Figure 14 The pad area PA may include a bending area BA, a first sub-pad area PDA, and a second sub-pad area SDA. The second sub-pad area SDA may be disposed between the bending area BA and the first sub-pad area PDA. The scan driver 400 may be disposed in the second sub-pad area SDA.

The third fan-out line FL3 may be arranged in the second sub-pad area SDA. The third fan-out line FL3 may be connected to the second fan-out line FL2 through a third wiring connection hole FCT3 in a portion of the second sub-pad area SDA adjacent to the bending area BA. The second fan-out line FL2 may be arranged in the bending area BA. The second fan-out line FL2 may be connected to the connection line CL through a second wiring connection hole FCT2 in the non-display area NDA.
[0200] The first fan-out lines FL1 may be alternately arranged in the first gate metal layer GTL1 and the second gate metal layer GTL2. The third fan-out lines FL3 may be arranged in the second source metal layer DTL2. In another example, the third fan-out lines FL3 may be alternately arranged in the second source metal layer DTL2 and the third source metal layer DTL3. The second fan-out lines FL2 may be alternately arranged in the first source metal layer DTL1 and the second source metal layer DTL2. In this case, the first wiring connection hole FCT1 may be a hole that passes through the second planarizing film 180, the first planarizing film 160, the passivation film 150, and the second interlayer insulating film 142, or a hole that passes through the first planarizing film 160, the passivation film 150, the second interlayer insulating film 142, and the first interlayer insulating film 141. In addition, the third wiring connection hole FCT3 may be a hole that passes through the first planarizing film 160 or a hole that passes through the second planarizing film 180.

Alternatively, the second wiring connection hole FCT2 may be a hole penetrating the second planarization film 180 .
[0201] according to Figure 14 In an embodiment, since the scan driver 400 can be set in the pad area PA instead of the non-display area NDA, the difference between the width of the portion of the non-display area NDA located at the outer left side of the display area DA and the width of the portion of the non-display area NDA located at the outer right side of the display area DA can be minimized.
[0202] Figure 15 is a plan view illustrating a display panel, a display driver, and a scan driver of a display device according to another embodiment.
[0203] exist Figure 15 In an embodiment of the present invention, the connection line CL may be connected to the data line DL in the non-display area NDA instead of in the display area DA.
[0204] Reference Figure 15 , the connection lines CL may include horizontal connection lines HCL extending in a first direction (or X-axis direction) and vertical connection lines VCL extending in a second direction (or Y-axis direction).
[0205] In the non-display area NDA, the horizontal connection line HCL may be connected to the second fan-out line FL2 through the second wiring connection hole FCT2. The vertical connection line VCL may be connected to the data line DL through the connection hole CT. The data line DL may be connected to the vertical connection line VCL through the connection hole CT. The vertical connection line VCL may be connected to the data line DL one-to-one.
[0206] In the non-display area NDA, the vertical connection line VCL may be connected to the data line DL through the connection hole CT. That is, the connection hole CT may be provided in the non-display area NDA. Figure 15 The vertical connection line VCL is shown to be disposed in a portion of the non-display area NDA located at the outer lower side of the display area DA, but the embodiment is not limited thereto. For example, the vertical connection line VCL may be disposed in a portion of the non-display area NDA located at the outer upper side of the display area DA.
[0207] according to Figure 15 In an embodiment, the pad area PA, in which the display driver 200 may be disposed, may protrude from the non-display area NDA in a first direction (or X-axis direction), the first direction (or X-axis direction) intersecting the direction in which the data lines DL extend (i.e., the second direction (or Y-axis direction). Therefore, the data lines DL extending in the second direction (or Y-axis direction) may receive data voltages from the display driver 200 via the horizontal connection lines HCL extending in the first direction (or X-axis direction) and the vertical connection lines VCL extending in the second direction (or Y-axis direction).
[0208] In addition, according to Figure 15 In an embodiment, when the pad area PA protrudes from the non-display area NDA in the first direction (or the X-axis direction), the length of the pad area PA in the second direction (or the Y-axis direction) can be greater than the length of the pad area PA in the first direction (or the X-axis direction). This can facilitate the design and / or arrangement of the fan-out line FL connecting the display area DA and the pad area PA. Therefore, the difference between the width of the portion of the non-display area NDA located on the outer left side of the display area DA and the width of the portion of the non-display area NDA located on the outer right side of the display area DA can be minimized.

Therefore, the first data line DL1, the second data line DL2, and the third data line DL3 extending in the second direction (or the Y-axis direction) can receive data voltages from the display driver 200 via the horizontal connection lines HCL1, HCL2, and HCL3 extending in the first direction (or the X-axis direction) and the vertical connection lines VCL1, VCL2, and VCL3 extending in the second direction (or the Y-axis direction).

The odd data lines DLO and the even data lines DLE can extend in the second direction (or Y-axis direction). The odd data lines DLO can be arranged to be adjacent to their respective even data lines DLE in the first direction (or X-axis direction). For example, the first odd data line and the first even data line can be arranged to be adjacent to each other in the first direction (or X-axis direction), and the second odd data line and the second even data line can be arranged to be adjacent to each other in the first direction (or X-axis direction).

The area of the demultiplexer 410 may be smaller than that of the scan driver 400. Therefore, the length of the demultiplexer 410 in the second direction (or Y-axis direction) may be smaller than the length of the scan driver 400 in the second direction (or Y-axis direction).
[0237] The demultiplexer 410 can distribute the data voltage applied to each fan-out line FL among the connection lines CL. The number of fan-out lines FL connected to the demultiplexer 410 can be smaller than the number of connection lines CL connected to the demultiplexer 410. Because the number of fan-out lines FL provided in the pad area PA can be reduced by half or more, the distance between the fan-out lines FL can be widened. In other words, the complexity of the wiring in the pad area PA can be reduced.
[0238] The third fan-out line FL3 may be provided in a portion of the non-display area NDA located at the outer right side of the display area DA. In the portion of the non-display area NDA located at the outer right side of the display area DA, the third fan-out line FL3 may be connected to the second fan-out line FL2 via a second wiring connection hole FCT2.

Due to the presence of the second power line VDDL, the first connection line CL1, the first odd data line DLO1, and the first even data line DLE1 may overlap with the second power line VDDL. The second power line VDDL may prevent coupling between the first connection line CL1 and the driving transistor DT, between the first connection line CL1 and the sixth transistor ST6, between the first odd data line DLO1 and the driving transistor DT, and between the first even data line DLE2 and the sixth transistor ST6.

For example, the first odd data line and the first even data line can be arranged to be adjacent to each other in the first direction (or X-axis direction), and the second odd data line and the second even data line can be arranged to be adjacent to each other in the first direction (or X-axis direction). The distance between the first odd data line and the first even data line in the first direction (or X-axis direction) can be smaller than the distance between the first even data line and the second odd data line in the first direction (or X-axis direction).

The demultiplexer 410 may be disposed in a portion of the non-display area NDA located on the outer right side of the display area DA. The area of the demultiplexer 410 may be smaller than that of the scan driver 400. Therefore, the length of the demultiplexer 410 in the second direction (or Y-axis direction) may be smaller than the length of the scan driver 400 in the second direction (or Y-axis direction).
[0252] The demultiplexer 410 can distribute the data voltage applied to each fan-out line FL among the connection lines CL. The number of fan-out lines FL connected to the demultiplexer 410 can be smaller than the number of connection lines CL connected to the demultiplexer 410.
