Description

This application claims priority over Korean patent application no. 10-2024-0200171, filed on December 30, 2024. BACKGROUND Technical field The present disclosure relates to a display device that displays images. Description of the related area Since an organic light-emitting display device has a high response speed and low power consumption, and unlike a liquid crystal display device emits light itself without requiring a separate light source, there is no problem with a viewing angle, and thus the organic light-emitting display device has received attention as a next-generation flat panel display device. The display device contains several subpixels, and these subpixels contain a layer of light-emitting elements arranged in a light-emitting surface. The display device shows an image by emitting light from the layer of light-emitting elements. SUMMARY In conventional display devices, a repair line is typically provided between the light-emitting area and a circuit area to prevent the entire light-emitting area of ​​each subpixel from becoming inoperative due to a short circuit between leads or electrodes. However, when located within the light-emitting area, the repair line reduces the space available for light emission, thereby decreasing the luminous efficacy. As a result, the presence of the repair line limits the expansion of the light-emitting area and hinders improvements in luminous efficacy. Various embodiments of the display device disclosed herein improve the light emission efficiency and / or repairability by structurally relocating the repair section to a non-light emission area positioned within each subpixel but outside the active emission areas. This arrangement allows for an increased area dedicated to light emission compared to conventional configurations. Additionally, reflective surfaces in inner and outer non-light emission areas can be angled to redirect light guided by a waveguide to the substrate, thus recovering light that would otherwise be lost. The repair areas can be further protected by overlaying color filters, such as blue filters, onto white subpixels to act as laser shields during repair and reduce the risk of damage to the reflecting electrode. The repair contact surfaces can be designed with a width that balances effective laser target alignment with minimal interference with the light output. Subpixels can be formed with multiple light emission areas connected by narrow bridge sections that can be selectively severed if defects occur. This structure enables partial subpixel operation following localized damage and can be supplemented by weld lines that redirect electrical paths, thereby supporting improved repair flexibility and light emission performance. One objective of the present disclosure is to provide a display device in which the size (or area) of a light-emitting surface can be extended. One objective of the present disclosure is to provide a display device that can improve the light output. One objective of the present disclosure is to provide a display device in which the light extraction efficiency of light emitted by a layer of light-emitting elements can be maximized. One object of the present disclosure is to provide a display device in which the overall power consumption can be reduced by light extraction in a non-light-emitting surface. At least one of these problems can be solved by the features of the independent claim. The problems that embodiments of the present disclosure are intended to solve are not limited to those mentioned above, and further problems not mentioned above will become clear to those skilled in the art in the field to which the technical ideas of the present disclosure belong from the following descriptions.

DETAILED DESCRIPTION Reference will now be made in detail to the embodiments of the present disclosure, examples of which are shown in the accompanying drawings. Where possible, the same reference numerals are used throughout the drawings to refer to the same or similar parts. Advantages and features of the present disclosure and its implementation methods are illustrated by the following embodiments, which are described with reference to the accompanying drawings. The present disclosure may, however, be embodied in various forms and should not be interpreted as being limited to the embodiments set forth herein. Rather, these embodiments are provided to ensure that this disclosure is thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. When temporally relative terms such as "after", "following", "next", "before" and the like are used to describe processes or operations of elements or configurations or sequences or steps in operating, processing or manufacturing procedures, these terms may be used to describe non-consecutive or non-sequential processes or operations, provided they are not used together with the term "direct" or "immediately". A dimension, including the size and thickness of each component illustrated in the drawing, is shown for the convenience of description, and the present disclosure is not limited to the size and thickness of the component illustrated, but it should be noted that the relative dimensions, including the relative size, location and thickness of the components illustrated in various drawings hereby submitted, are part of the present disclosure. Similar reference symbols refer to similar elements throughout. In the following description, if it is determined that a precise description of the relevant known function or configuration would unnecessarily obscure the important point of the present disclosure, the precise description will be omitted. If 'comprise', 'possess', and 'contain', as described in this disclosure, are used, a further part may be added, unless 'merely' is used. Singular terms may contain plural forms unless otherwise stated. When an element is laid out, it is laid out as if it contains a fault area, even though there is no explicit description. When describing a positional relationship, for example, when a positional relationship between two parts is described as 'at~', 'above~', 'below~', and 'next to~', one or more other parts may be positioned between the two parts unless 'only' or 'directly' is used. When describing a temporal relationship, e.g., when the temporal sequence is described as "after", "subsequent", "next" and "before", a case that is not continuous may be included unless "only" or "direct" is used. As used here, the term "connected" is intended to have the broadest possible meaning. Specifically, the phrase "A is connected to B" encompasses both a direct connection—where no intervening components or elements are present—and an indirect connection, where one or more intervening components or elements exist between A and B. In other words, "A is connected to B" includes both a direct physical or electrical coupling and an indirect coupling via one or more intervening components. Unless explicitly stated otherwise, these expressions do not require direct physical or electrical contact. The expressions "coupled" and "in contact" are to be interpreted in the same way. It will be understood that, although the terms "first", "second", etc. may be used here to describe different elements, the elements should not be limited by these terms. These terms are used merely to distinguish one element from another. For example, a first element could be called a second element, and conversely, a second element could be called a first element, without altering the scope of the present disclosure. "X-axis direction, "Y-axis direction" and "Z-axis direction" are not to be interpreted by a geometric relationship of merely a mutual vertical relationship and may have a wider orientation to the extent that elements of the present disclosure may expediently function. The expression "at least one" should be understood to include all combinations of one or more of the associated listed elements. For example, the meaning of "at least one of a first element, a second element and a third element" refers to the combination of all elements proposed from two or more of the first element, the second element and the third element, as well as the first element, the second element or the third element. Features of different embodiments of the present disclosure can be partially or completely coupled or combined with one another and can interact with each other and be controlled technically in different ways, as skilled persons can reasonably understand. The embodiments of the present disclosure can be carried out independently of one another or can be carried out together in a dependent relationship. The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. Fig. 1 is a schematic top view of a display device according to an embodiment of the present disclosure, Fig. 2 is a schematic top view of a pixel (shown in Fig. 1), Fig. 3 is a top view schematically showing a repair section and branch lines in Fig. 2, and Fig. 4 is a schematic top view showing a subpixel of a display device according to an embodiment of the present disclosure and a subpixel of a display device according to a comparative example. In the following, a first direction (a Y-axis direction) represents a vertical direction based on Fig. 1, a second direction (an X-axis direction) represents a horizontal direction based on Fig. 1, and a third direction (a Z-axis direction) represents a thickness direction of a display device 100. The first direction (the Y-axis direction) can be a direction parallel to a data line DL (shown in Fig. 2). The second direction (the X-axis direction) can be a direction parallel to a gate line GL (shown in Fig. 2). Referring to Fig. 1, a display device 100 according to an embodiment of the present disclosure can include a display panel having a gate driver GD. The display panel can include a substrate 110 and an opposing substrate 200 (shown in Fig. 5) connected to each other. The substrate 110, according to one example, can include a display area DA in which several pixels P, each containing several subpixels SP, are arranged, and a non-display area NDA surrounding the display area DA. The substrate 110 can further include a first non-emissive area NEA1, a second non-emissive area NEA2, a light-emitting area EA, and a repair structure RPP (also referred to as a 'repair section RPP'). The first non-emissive area NEA1, the second non-emissive area NEA2, the light-emitting area EA, and the repair section RPP can be provided within the display area DA of the substrate 110. Each of the first non-light-emitting surface NEA1 and the second non-light-emitting surface NEA2 can be a surface from which no light is emitted. In contrast, the light-emitting surface EA can be a surface from which light is emitted. According to one example, the first non-light-emitting surface NEA1 is provided on the substrate 110 and can be located on the inside of each of the multiple subpixels SP. For example, as shown in Fig. 2, the first non-light-emitting surface NEA1 can be located on the inside of the light-emitting surface EA of each of the multiple subpixels SP (or between the light-emitting surfaces EA). According to one example, each light-emitting surface EA of several subpixels SP can contain a first light-emitting surface EA1, a second light-emitting surface EA2, and a third light-emitting surface EA3. The first light-emitting surface EA1 can be connected to the second light-emitting surface EA2 by a first connecting section CP1. The second light-emitting surface EA2 can be connected to the third light-emitting surface EA3 by means of a second connecting section CP2. Each of the first connecting section CP1 and the second connecting section CP2 can be a light-emitting surface EA. As shown in Fig. 2, the first non-light-emitting surface NEA1 can, according to one example, be arranged between the first light-emitting surface EA1 and the second light-emitting surface EA2, and between the second light-emitting surface EA2 and the third light-emitting surface EA3. For example, the second non-emissive surface NEA2 can be connected to the first non-emissive surface NEA1. The second non-emissive surface NEA2 can be an area between the multiple subpixels SP. Similarly, the first non-emissive surface NEA1 and the second non-emissive surface NEA2 can be provided to surround the light-emitting surface EA. Therefore, the light-emitting surface EA can be provided adjacent to both the first non-emissive surface NEA1 and the second non-emissive surface NEA2. The repair section RPP is designed to prevent the entire light emission area EA of each subpixel SP from becoming dark due to a short circuit between the leads (or electrodes) contained in substrate 110. For example, the repair section RPP can forward a laser pulse LS (shown in Fig. 6) received from a laser device to a line (e.g., a data branch line BRL1 (shown in Fig. 6)), causing the line (e.g., the data branch line BRL1 (shown in Fig. 6)) to be cut in the repair section RPP. Similarly, according to one embodiment of the present disclosure, the display device 100 can prevent the entire light-emitting area EA of each subpixel SP from becoming dark (or unable to be driven or unable to emit light) due to a short circuit between lines (e.g., data lines and scanning lines) (or electrodes). In the display device 100 according to an embodiment of the present disclosure, a repair section RPP can be provided in the first non-light-emitting surface NEA1. In the case of a general-purpose display, no repair line (or repair section) is provided within each of the multiple subpixels (or within the light-emitting area). If the repair line (or repair section) were provided within each of the multiple subpixels (or within the light-emitting area), the size (or area) of the light-emitting area would be reduced, thereby decreasing the luminous efficacy. Therefore, in the case of a general-purpose display, the repair line (or repair section) is located outside the light-emitting area. In contrast, the display device 100 according to an embodiment of the present disclosure can have the repair section RPP which is provided in the first non-light-emitting surface NEA1 which is located within each of the multiple subpixels SP. For example, as shown in Fig. 4, in the case of a general display device CDP, a repair section RPP containing a subpixel SP is arranged between the light-emitting surface EA and a circuit surface CA. Similarly, in the case of the general display device CDP, a light-emitting surface EA having a first length W1 (or a first width W1) and a repair section RPP having a second length W2 (or a second width W2) can be provided on a top surface of the circuit surface CA. In contrast, according to one embodiment of the present disclosure, the display device 100 can be provided with the repair section RPP in the first non-light-emitting surface NEA1 in each of the multiple subpixels SP, such that the light-emitting surface EA can have a third length W3 (or a third width W3). The third length W3 (or the third width W3) can be a length (or width) that is the sum of the first length W1 (or the first width W1) and the second length W2 (or the second width W2). Therefore, the display device 100 according to an embodiment of the present disclosure can have an increased size (or area) of the light emission area EA compared to the display device CDP according to a comparative example, such that the light output can be further improved. Meanwhile, in the case of a general display device, if a non-light-emitting area is provided within each of the multiple subpixels, the light output may be reduced. However, since the display device 100 according to an embodiment of the present disclosure is provided with a first reflective section 121 (shown in Fig. 6) in the first non-light-emitting surface NEA1, light extraction can be achieved through the first reflective section 121 in such a way that the light output does not have to be reduced. As a result, the display device 100 according to an embodiment of the present disclosure cannot have the luminous efficacy that is reduced due to the first reflective section 121 in the first non-luminous emission surface NEA1, even when the first non-luminous emission surface NEA1 is arranged within each of the multiple subpixels SP, and since the size (or area) of the luminous emission surface EA can be extended by providing the repair section RPP in the first non-luminous emission surface NEA1, the luminous efficacy can be improved. Referring to Fig. 1, a display device 100 according to an embodiment of the present disclosure may include an integrated source control circuit (hereinafter referred to as “IC”) 130, a flexible thin layer 140, a printed circuit board 150 and a timing control section 160. Substrate 110 can contain a thin-film transistor and can be a transistor array substrate, a bottom substrate, a base substrate, or a first substrate. Substrate 110 can be a transparent glass substrate or a transparent plastic substrate. The opposing substrate 200 can be connected to the substrate 110 by means of an adhesive element. For example, the opposing substrate 200 is smaller than the substrate 110 and can be connected to a remaining section of the substrate 110, excluding a connecting surface section. The opposing substrate 200 can be an upper substrate, a second substrate, or an encapsulating substrate. The gate driver GD supplies gate signals to the gate lines according to the gate control signal input from the timing section 160. If the source driver IC 130 is manufactured as a driver chip, it can be assembled in the flexible thin layer 140 using a chip-on-thin-film (COF) process or a chip-on-plastic (COP) process. Connection pads, such as data pads, can be formed in the non-display area of ​​the display panel. Traces connecting the connection pads to the source driver IC 130 and traces connecting the connection pads to traces of the printed circuit board 150 can be formed in the flexible thin layer 140. The flexible thin layer 140 can be attached to the connection pads using a thin anisotropic conductive layer, thereby connecting the connection pads to the traces of the flexible thin layer 140. Referring to Fig. 1, the substrate 110 can, according to one example, contain a display area DA and a non-display area NDA. The display area DA is an area in which an image is displayed and can be a pixel array area, an active area, a pixel array unit, a display unit, or a screen. For example, the display area DA can be located in a central section of the scoreboard. The display area DA, according to one example, can contain gate lines, data lines, pixel power supply lines, and multiple pixels P. Each of the multiple pixels P can contain multiple subpixels SP, which can be defined by gate lines and data lines. Each of the multiple subpixels SP can be defined as the smallest area unit in which actual light is emitted. According to one example, at least four subpixels SP, arranged adjacent to each other and configured to emit different colors, form a pixel unit P among several subpixels SP. This single pixel unit may contain, but is not limited to, a red subpixel, a white subpixel, a blue subpixel, and a green subpixel. Each of the multiple subpixels SP can contain a thin-film transistor and an organic light-emitting element connected to the thin-film transistor. The subpixel can contain an organic light-emitting layer (or a light-emitting layer) positioned between a first electrode and a second electrode. The organic light-emitting layer arranged in each of the multiple subpixels SP can emit light of different colors individually or emit white light collectively. For example, if the organic light-emitting layer of each of the multiple subpixels SP emits white light collectively, each of the red, green, and blue subpixels can contain a color filter CF (or a wavelength conversion element CF) that converts the white light into light of a different color. In this case, the white subpixel, according to one example, need not have a color filter. The color filter CF, according to one example, can contain a red color filter CF1 (shown in Fig. 2), a blue color filter CF2 (shown in Fig. 2), and a green color filter (shown in Fig. 2). In the display device 100 according to an embodiment of the present disclosure, an area provided with the red color filter CF1 can be a red subpixel SP1, an area provided with the blue color filter CF2 can be a blue subpixel SP3, an area provided with the green color filter can be a green subpixel SP4, and an area without the color filter can be a white subpixel SP2.In the present disclosure, the red subpixel SP1 can be represented as a first subpixel equipped to emit red light, the blue subpixel SP3 can be represented as a third subpixel equipped to emit blue light, the green subpixel SP4 can be represented as a fourth subpixel equipped to emit green light, and the white subpixel SP2 can be represented as a second subpixel equipped to emit white light. Each of the subpixels SP supplies a predetermined current to the organic light-emitting element according to a data voltage on the data line when a gate signal is input from the gate line using the thin-film transistor. Therefore, the light-emitting layer of each subpixel can emit light at a predetermined brightness according to the predetermined current. The display area DA can contain a light-emitting surface EA and a non-light-emitting surface NEA. The light-emitting surface EA is the area where light is emitted through layer E of organic light-emitting elements. The non-light-emitting surface NEA is the area that does not transmit most of the light incident from the outside. For example, the non-light-emitting area NEA can be an area other than the light-emitting area EA, from which light is emitted. In one example, the non-light-emitting area NEA can contain a circuit area CA (shown in Fig. 2). The circuit area CA can contain a thin-film transistor 112 for driving each of the multiple subpixels SP (or the layer E of organic light-emitting elements of each of the multiple subpixels SP). In the display device 100 according to an embodiment of the present disclosure, the non-light-emitting surface NEA can comprise a first non-light-emitting surface NEA1 and a second non-light-emitting surface NEA2. According to one example, the first non-light-emitting surface NEA1 can be provided on the inside of each of the multiple subpixels SP. For example, as shown in Fig. 2, the inside of each of the multiple subpixels SP can be the inside of the light-emitting surface EA contained within a subpixel SP. The layer E of organic light-emitting elements (shown in Fig. 5) need not be located within the first non-light-emitting surface NEA1. According to one example, the second non-emissive surface NEA2 can be provided on an outer surface of each of the multiple subpixels SP. For example, as shown in Fig. 2, an outer surface of each of the multiple subpixels SP can be located between the multiple subpixels SP. Accordingly, the second non-emissive surface NEA2 can be distinguished from the first non-emissive surface NEA1, which is positioned between the light-emitting surface EA (e.g., the first light-emitting surface EA1 and the second light-emitting surface EA2) contained within a subpixel SP. The outer surface of each of the multiple subpixels SP, e.g., the second non-emissive surface NEA2, can include a circuit surface CA adjacent to the light-emitting surface EA. Additionally, the outer surface of each of the multiple subpixels SP can be an area located between the multiple subpixels SP (e.g., the pixel electrodes 114 (shown in Fig.5 shown) each of the first subpixel SP1 and the second subpixel SP2) contain, which emit light of different colors. Additionally, the non-light-emitting surface (NEA) can contain multiple pixels P and multiple lines for controlling each of these pixels P. The multiple lines, as in one example, can include multiple first signal lines and multiple second signal lines. The multiple first signal lines can extend in the second direction (the X-axis direction). Each of the multiple first signal lines can contain at least one gate line GL (or a sampling line). The multiple second signal lines can extend in the first direction (the Y-axis direction). The multiple second signal lines can intersect the multiple first signal lines. Each of the multiple second signal lines can contain a pixel power supply line EVDD, multiple data lines DL, and a reference line RL. The multiple data lines DL can contain a first data line to drive the first subpixel SP1, a second data line to drive the second subpixel SP2, a third data line to drive the third subpixel SP3, and a fourth data line to drive the fourth subpixel SP4. Referring again to Fig. 1, the non-display area (NDA) is an area in which no image is displayed and can be a peripheral circuit area, a signal input area, an inactive area, or a border area. The non-display area (NDA) can be configured to be close to the display area (DA). That is, the non-display area (NDA) can be arranged to surround the display area (DA). The display device 100 according to one embodiment of the present disclosure can include a connection area section PA arranged in the non-display area NDA. The connection area section PA can be used to control the multiple pixels P. For example, the connection area section PA can supply power and / or signals so that the multiple pixels P arranged in the display area DA output images. According to one example, the connection surface section PA can be arranged in the non-display area NDA (or the first non-display area NDA1) above the display area DA, based on Fig. 1. The gate driver GD supplies gate signals to the gate lines according to the gate control signal input from the timing control unit 181. The gate driver GD can be located on one side of the display area DA of the display panel or on the non-display area NDA outside both sides of the display area DA in a gate driver in panel-type GIP configuration, as shown in Fig. 1. The multiple gate drivers GD can be arranged separately on a left side of the display area DA, i.e. the second non-display area, and on a right side of the display area DA, i.e. the third non-display area. For example, the multiple gate drivers GD can be connected to the multiple pixels P and the multiple first signal lines for supplying signals to the multiple pixels P. The multiple first signal lines can include at least one signal line for supplying a signal to control pixel P. The multiple second signal lines can extend in the first direction (the Y-axis direction). The multiple second signal lines can include a pixel power supply line EVDD and at least one data line DL to supply a data voltage to pixel P. Each of the multiple second signal lines can be connected to at least one of several connection surfaces, a pixel power shorting bar, and a common power shorting bar. The pixel power shorting bar and the common power shorting bar can be located in a fourth non-display surface facing a connection surface section PA based on the display surface DA. The pixels P are configured to overlap with at least one of the first signal lines or the second signal line and emit predetermined light to display an image. The light-emitting area EA can correspond to a light-emitting surface within the pixel P. The non-light-emitting area (NEA) can refer to an area provided within the display area (DA) that emits no light and can be expressed as a dead zone because it does not emit light. The dead zone, as in one example, could be an area containing a black matrix and / or a bank, but is not limited to this and can refer to any area from which no light is emitted. According to one embodiment of the present disclosure, the display device 100 can improve the luminous efficacy by enabling the size (or area) of the light-emitting surface EA to be extended (or enlarged) by arranging the repair section RPP in the first non-light-emitting surface NEA1, which is a dead zone, and a repair process can be carried out by the repair section RPP. In the display device 100 according to an embodiment of the present disclosure, a repair section RPP can be arranged in a first non-light-emitting surface NEA1. For example, as shown in Fig. 3, a light-emitting surface EA, contained in a subpixel SP, can contain a first light-emitting surface EA1, a second light-emitting surface EA2, and a third light-emitting surface EA3, which are sequentially connected in a first direction (a Y-axis direction) (or a downward direction based on Fig. 3) by a first connecting section CP1 and a second connecting section CP2. Since the layer E of organic light-emitting elements is also arranged in each of the first connecting section CP1 and the second connecting section CP2, light can be emitted from each of the first connecting section CP1 and the second connecting section CP2.Accordingly, the light emission surface EA contained in a subpixel SP can be the first light emission surface EA1, the first connecting section CP1, the second light emission surface EA2, the second connecting section CP2 and the third light emission surface EA3, which are sequentially connected in the first direction (the Y-axis direction) (or the downward direction based on Fig. 3). Meanwhile, according to one embodiment of the present disclosure, the display device 100 can prevent the entire light-emitting area EA of each subpixel SP from being darkened by foreign substances generated during the manufacturing process. For example, if a foreign substance adheres to one or two of the first light-emitting area EA1, the second light-emitting area EA2, and the third light-emitting area EA3, the first connecting section CP1 (or the second connecting section CP2) is cut by a laser device such that the light-emitting area (e.g., the first light-emitting area EA1) to which the foreign substance adheres becomes dark, and the remaining light-emitting areas (e.g., the second light-emitting area EA2 and the third light-emitting area EA3) can be driven normally (or somewhat darkened). For this purpose, the display device 100 according to one embodiment of the present disclosure can be provided such that a width CW (shown in Fig. 2) of the first connecting section CP1 is narrower than a width EW of the first light-emitting surface EA1. If the width CW of the first connecting section CP1 is equal to or wider than the width EW of the first light-emitting surface EA1, a conductor connected to the organic layer E of light-emitting elements or the circuit surface CA may be damaged during a cutting process in which a laser device cuts through the first connecting section CP1. Accordingly, in the display device 100 according to one embodiment of the present disclosure, the width CW (shown in Fig. 2) is(as shown in Figure 2) the width of the first connection section CP1 is provided to be narrower than the width EW of the first light-emitting surface EA1, such that damage to the conductors connected to the organic layer E of light-emitting elements or the circuit surface CA can be prevented during the cutting process of the first connection section CP1. For the same reason as above, the width of the second connection section CP2 can be provided to be equal to the width of the first connection section CP1. Referring to Fig. 3, the repair section RPP can, according to one example, be located in the first non-light-emitting area NEA1, which is provided between the second emission area EA2 and the third emission area EA3. The repair section RPP is designed to prevent the entire light-emitting area EA from going dark (or becoming inoperable or unable to emit light) due to a short circuit between leads (or electrodes). Therefore, the repair section RPP can be located near the circuit area CA to disconnect a lead connected to the circuit area CA (or a thin-film transistor 112 of the circuit area CA). Similarly, the repair section RPP can be provided in the first non-light-emitting area NEA1, which is located near the circuit area CA. For example, as shown in Fig.As shown in Figure 3, the repair section RPP is arranged in the first non-light-emitting surface NEA1, which is provided between the second emission surface EA2 and the third emission surface EA3. However, the present disclosure is not limited to this and, depending on a circuit design, the repair section RPP can be arranged in the first non-light-emitting surface NEA1, which is provided between the first light-emitting surface EA1 and the second light-emitting surface EA2. In the display device 100 according to an embodiment of the present disclosure, the substrate 110 may further include a data branch line BRL1 and a reference branch line BRL2. The data branch line BRL1 can be connected to any of the multiple subpixels SP. For example, as shown in Fig. 3, the data branch line BRL1 in the first subpixel SP can be electrically connected to the circuit area CA (or the thin-film transistor 112) and to a data line DL (or a first data line DL1) of the first subpixel SP. Accordingly, the data branch line BRL1 can transmit a data signal (or a data voltage) applied from the data line DL to the circuit area CA (or the thin-film transistor 112). The reference branch line BRL2 is spaced apart from the data branch line BRL1 and can be connected to any of the multiple subpixels SP. For example, as shown in Fig. 3, the reference branch line BRL2 in the first subpixel SP can be electrically connected to the circuit area CA (or the thin-film transistor 112) and the reference line RL of the first subpixel SP. Accordingly, the reference branch line BRL2 can detect a change in the characteristics of the thin-film transistor 112, located in the circuit area CA, during a detection drive mode of pixel P and transmit it to the reference line RL. Meanwhile, in the display device 100 according to an embodiment of the present disclosure, the repair section RPP can include a first repair section RPP1 and a second repair section RPP2. According to one example, the first repair section RPP1 can partially overlap with the data branch line BRL1. The first repair section RPP1 serves to cut the data branch line BRL1 if a short circuit occurs in the data line DL. For example, the first repair section RPP1 can cut the data branch line BRL1 by forwarding the laser pulse LS (shown in Fig. 6), received from the laser device, to the data branch line BRL1. According to one embodiment of the present disclosure, the display device 100 connects a pixel electrode 114 in a subpixel SP where a short circuit occurs and a circuit surface CA in another subpixel SP (e.g., a subpixel SP adjacent to a top surface with respect to Fig. 3) by means of a weld path WDL (shown in Fig. 10) (or a welding process) after the data branch line BRL1 has been cut by the first repair section RPP1, thereby enabling the light-emitting surface EA of the subpixel SP where a short circuit occurs to be driven together with a light-emitting surface EA of the further subpixel SP. This will be described later with reference to Fig. 10. The second repair section RPP2, as in one example, can partially overlap with the reference branch line BRL2. The second repair section RPP2 serves to cut the reference branch line BRL2 if a short circuit occurs in the reference line RL. For example, the second repair section RPP2 can cut the reference branch line BRL2 by forwarding a laser pulse LS received from a laser device to the reference branch line BRL2. According to one embodiment of the present disclosure, the display device 100 connects a pixel electrode 114 in a subpixel SP in which a short circuit occurs and a circuit surface CA in another subpixel SP (e.g., a subpixel SP adjacent to a top surface with respect to Fig. 3) by means of a weld path WDL (shown in Fig. 10) (or a welding process) after the reference branch line BRL2 has been cut by the second repair section RPP2, thereby enabling the light-emitting surface EA of the subpixel SP in which a short circuit occurs to be controlled together with a light-emitting surface EA of the further subpixel SP. This will be described later with reference to Fig. 10. Therefore, according to one embodiment of the present disclosure, the display device 100 can prevent the entire light emission area EA of each subpixel SP from becoming dark due to a short circuit in the data line DL or the reference line RL. As shown in Fig. 3, each of the first repair section RPP1 and the second repair section RPP2 can be provided in an island configuration. Since each of the first repair section RPP1 and the second repair section RPP2 receives a laser pulse from a laser device, if each of the first repair section RPP1 and the second repair section RPP2 is connected to a different lead or electrode, the laser pulse can be directed to the different lead or electrode and cause damage. Therefore, the indicator device 100 according to one embodiment of the present disclosure can have a structural feature in which each of the first repair section RPP1 and the second repair section RPP2 is provided in an island configuration. Meanwhile, with reference to Fig. 3, each of the data branch line BRL1 and the reference branch line BRL2 can partially overlap with the light-emitting surface EA. Similarly, each of the data branch line BRL1 and the reference branch line BRL2 can be formed from a transparent conductor material (or a transparent line). In a bottom-emitting configuration, if the data branch line BRL1 and the reference branch line BRL2 are provided as opaque lines, they will block light emitted from the organic light-emitting layer 116 and directed towards the substrate 110, thereby reducing the light yield.Therefore, in the display device 100 according to an embodiment of the present disclosure, since each of the data branch line BRL1 and the reference branch line BRL2 is provided as the transparent conductor material (or the transparent line), a repair structure can be provided while preventing the reduction of the light output. The following section describes in detail the structure of each of the several subpixels SP with reference to Fig. 5, Fig. 6, Fig. 7 to Fig. 8. Fig. 5 is a schematic cross-sectional view taken along line II' (shown in Fig. 3), Fig. 6 is a schematic cross-sectional view taken along line II-II' (shown in Fig. 3), Fig. 7 is a schematic cross-sectional view taken along line III-III' (shown in Fig. 3), and Fig. 8 is a schematic cross-sectional view taken along line IV-IV' (shown in Fig. 3). Referring to Fig. 5, the display device 100 according to an embodiment of the present disclosure can include a buffer layer BL, several inorganic thin layers 111, a thin-film transistor 112, a color filter CF (shown in Fig. 8), a planarization layer 113, a pixel electrode 114, a bank 115, an organic light-emitting layer 116, a reflective electrode 117 and an encapsulation layer 118. Each of the subpixels SP according to an embodiment can contain the multiple inorganic thin layers 111 provided on an upper surface of the buffer layer BL, which includes a gate isolation layer 111a, an isolation intermediate layer 111b and a passivation layer 111c. Furthermore, each of the subpixels SP can contain a color filter CF (shown in Fig. 8) provided on the multiple inorganic thin layers 111, and a planarization layer 113 provided on the color filter CF. The planarization layer 113 can contain a first planarization layer 1131 and a second planarization layer 1132. The second planarization layer 1132 can be arranged on top of the first planarization layer 1131. A pixel electrode 114 can be arranged on the second planarization layer 1132. Each of the subpixels SP can further comprise a bank 115 covering an edge of the pixel electrode 114, an organic light-emitting layer 116 on the pixel electrode 114 and the bank 115, and a reflective electrode 117 on the organic light-emitting layer 116. The encapsulation layer 118 can be arranged on the reflective electrode 117. The thin-film transistor 112 for controlling a subpixel SP can be arranged on the multiple inorganic thin layers 111. The multiple inorganic thin layers 111 can also be expressed with respect to a circuit element layer. The buffer layer BL can be contained within the several inorganic thin layers 111 together with the gate insulating layer 111a, the insulating intermediate layer 111b, and the passivation layer 111c. The pixel electrode 114, the organic light-emitting layer 116, and the reflecting electrode 117 can be contained within a layer E of light-emitting elements. The buffer layer BL can be formed between the substrate 110 and the gate insulating layer 111a to protect the thin-film transistor 112. The buffer layer BL can be arranged over the entire surface (or the front surface) of the substrate 110. The buffer layer BL can serve to block the dispersion of a material contained in the substrate 110 into a transistor layer during a high-temperature manufacturing process of the thin-film transistor 112. The thin-film transistor 112 (or a drive transistor) according to an example can contain an active layer 112a, a gate electrode 112b, a source electrode 112c and a drain electrode 112d. The active layer 112a can contain a channel area, a drain area, and a source area formed within a thin-film transistor area of ​​a circuit area CA of the subpixel SP. The drain area and the source area can be spaced apart from each other by the channel area, which is arranged between them. The active layer 112a can be formed from a semiconductor material based on amorphous silicon, polycrystalline silicon, oxide and an organic material. The gate isolation layer 111a can be formed on the channel surface of the active layer 112a. For example, the gate isolation layer 111a can be formed in an island shape only on the channel surface of the active layer 112a, or it can be formed on the entire front surface of the substrate 110 or the buffer layer BL containing the active layer 112a. The gate electrode 112b can be formed on the gate insulation layer 111a to overlap with the channel area of ​​the active layer 112a. The insulating layer 111b can be formed such that it partially overlaps the gate electrode 112b and the drain and source areas of the active layer 112a. The insulating layer 111b can be formed over the entire light-emitting area where light is emitted, as shown in Fig. 3, in the circuit area CA and the subpixel SP. The source electrode 112c can be electrically connected to the source surface of the active layer 112a through a source contact hole provided in the insulating intermediate layer that overlaps with the source surface of the active layer 112a. The drain electrode 112d can be electrically connected to the drain surface of the active layer 112a through a drain contact hole provided in the insulating intermediate layer that overlaps with the drain surface of the active layer 112a. The drain electrode 112d and the source electrode 112c can be made of the same metal material. For example, each of the drain electrode 112d and the source electrode 112c can be made of a single metal layer, a single layer of an alloy, or a multiple layer of two or more layers, which may be the same or different from that of the gate electrode 112b. Additionally, the thin-film transistor provided in the pixel area may have a property in which the threshold voltage is shifted by light. To prevent this, the display panel or substrate 110 may further include a light-shielding layer LS, which is provided beneath the active layer 112a and contains at least one thin-film transistor 112, a first switching thin-film transistor, and a second switching thin-film transistor. The light-shielding layer LS is provided between the substrate 110 and the active layer 112a to block light passing through the substrate 110 onto the active layer 112a, thereby minimizing changes in the transistor's threshold voltage caused by external light. Additionally, the light-shielding layer LS can be provided between the substrate 110 and the active layer 112a to prevent the thin-film transistor from being visible to the user. The passivation layer 111c can be provided on the substrate 110 to cover the pixel area. The passivation layer 111c covers a drain electrode 112d, a source electrode 112c, and a gate electrode 112b of the thin-film transistor 112, as well as the buffer layer BL. The color filter CF (shown in Fig. 8) can be arranged on the passivation layer 111c. For example, the color filter CF can be arranged between the several inorganic thin layers 111 and the first planarization layer 1131. The color filter CF can include a red color filter CF1, located in the red subpixel SP1, a blue color filter CF2, located in the blue subpixel SP3, and a green color filter CF3, located in the green subpixel SP4. Since the white subpixel SP2 is provided to emit white light, it does not need to contain the color filter. The planarization layer 113 can be provided on the substrate 110 to cover the passivation layer 111c and the color filter CF. For example, the planarization layer 113 can be located between the substrate 110 and the pixel electrode 114. The planarization layer 113 can be formed across the entire circuit area CA, in which the thin-film transistor 112 is located, and across the entire light-emitting area EA. Additionally, the planarization layer 113 can be formed across the further non-display area NDA, excluding one terminal area PA of the non-display area NDA, and across the entire display area DA. For example, the planarization layer 113 can include an extension section (or an enlarged section) that extends from the display area DA to or enlarges the further non-display area NDA, excluding the terminal area PA.Therefore, the planarization layer 113 can have a size that is relatively wider than that of the display area DA. The planarization layer 113, as described in one example, can be formed to have a relatively large thickness, thereby providing a flat surface on both the display area DA and the non-display area NDA. For example, the planarization layer 113 can be made of an organic material such as photoacrylic, benzocyclobutene, polyimide, or fluoropolymer. The planarization layer 113 can contain a first planarization layer 1131 and a second planarization layer 1132 arranged on top of the first planarization layer 1131. The first planarization layer 1131 can be arranged on the substrate 110. The second planarization layer 1132 can be arranged on top of the first planarization layer 1131. By way of example, the second planarization layer 1132 can be partially arranged between the first planarization layer 1131 and the pixel electrode 114. The first planarization layer 1131 is provided to cover the passivation layer 111c and the color filter CF, such that it can be formed continuously across the multiple subpixels SP. In contrast, the second planarization layer 1132 can be formed discontinuously. For example, the second planarization layer 1132 can be formed discontinuously by forming a pattern section (or a first pattern section) in which the second planarization layer 1132 is partially removed in the first non-emissive surface NEA1. Accordingly, as shown in Fig. 6, several second planarization layers 1132 can be provided in an island configuration on the first planarization layer 1131. However, this is not limited to this, and the second planarization layers 1132 can also be formed continuously. Referring to Fig. 6, the upper surface of the second planarization layer 1132 can be flat. Similarly, the pixel electrode 114 on the second planarization layer 1132 can also be flat, as can the organic light-emitting layer 116 and the reflecting electrode 117, which are also formed thereon, in a flat shape. Since the pixel electrode 114, the organic light-emitting layer 116, and the reflecting electrode 117—i.e., the layer E of organic light-emitting elements—are flat within the light-emitting surface EA, the thicknesses of the pixel electrode 114, the organic light-emitting layer 116, and the reflecting electrode 117 within the light-emitting surface EA can be uniform. Consequently, the organic light-emitting layer 116 can emit light uniformly without variation within the light-emitting surface EA. The pixel electrode 114 can be formed on the second planarization layer 1132. As shown in Fig. 5, the pixel electrode 114 can be connected to the drain electrode or the source electrode of the thin-film transistor by a contact hole that penetrates the first planarization layer 1131 and the passivation layer 111c. An edge section on both sides of the pixel electrode 114 can be covered by the bank 115. Since Fig. 5 is a cross-sectional view in the first direction (the Y-axis direction), the bank 115 can be provided to cover a top and a bottom edge of the pixel electrode 114 based on a plane (e.g., Fig. 3). However, the bank 115 need not be arranged between the multiple subpixels SP.Accordingly, the display device 100 according to an embodiment of the present disclosure can be provided with a bankless structure in which the bank 115 is not arranged between the multiple subpixels SP that are arranged in the second direction (the X-axis direction). The pixel electrode 114 can be made of at least one transparent metal material or a semi-transparent metal material. Because the display device 100 is configured as the downward-emitting type according to one embodiment of the present disclosure, the pixel electrode 114 can be formed from a transparent conductor material (or TCO) such as indium tin oxide (ITO) or indium zinc oxide (IZO) that can transmit light, or from a semi-transparent conductor material such as magnesium (Mg), silver (Ag) or an alloy of Mg and Ag. Meanwhile, the material forming pixel electrode 114 may contain MoTi. Pixel electrode 114 may be a first electrode or an anode electrode. The bank 115 can be a non-emissive surface and can be located adjacent to the light-emitting surface EA of each of the multiple subpixels SP. For example, the bank 115 can be located within the non-emissive surface NEA (or the second non-emissive surface NEA2 on the upper and lower sides of the pixel electrode 114). The bank 115 can be formed to cover a portion of the edge of the pixel electrode 114. Similarly, the bank 115 can obstruct the pixel electrode 114 and the reflecting electrode 117 at the edge of the pixel electrode 114. The exposed portion of the pixel electrode 114 not covered by the bank 115 can be contained within the light-emitting section (or light-emitting surface EA). After the bank 115 has been formed, an organic light-emitting layer 116 can be formed to cover the pixel electrode 114 and the bank 115. Thus, the bank 115 can be partially provided between the pixel electrode 114 and the organic light-emitting layer 116. The bank 115 can be expressed in terms of thin pixel definition layers. The bank 115, according to one example, can comprise an organic material and / or an inorganic material. The organic light-emitting layer 116 can be formed on the pixel electrode 114 and the bank 115. The organic light-emitting layer 116 can be located beneath the reflecting electrode 117. For example, the organic light-emitting layer 116 can be located in the light-emitting area EA and the non-light-emitting area NEA (or the first non-light-emitting area NEA1 and the second non-light-emitting area NEA2). The organic light-emitting layer 116 can be positioned between the pixel electrode 114 and the reflecting electrode 117. Thus, when a voltage is applied to each of the pixel electrode 114 and the reflecting electrode 117, an electric field is generated between the pixel electrode 114 and the reflecting electrode 117. Therefore, the organic light-emitting layer 116 can emit light.The organic light-emitting layer 116 can be formed from several subpixels SP and a common layer provided on bank 115. The organic light-emitting layer 116 according to one embodiment can be configured to emit white light. The organic light-emitting layer 116 can contain multiple stacks that emit light of different colors. For example, the organic light-emitting layer 116 can contain a first stack, a second stack, and a charge-generating layer (CGL) located between the first and second stacks. The light-emitting layer can be configured to emit white light, and thus each of the multiple subpixels SP can contain a color filter CF suitable for a corresponding color. The first stack can be provided on the pixel electrode 114 and can be implemented in a structure in which a hole injection layer (HIL), a hole transport layer (HTL), an emission layer (EML(B)) and an electron transport layer (ETL) are sequentially stacked. The charge-generating layer can supply electrical charge to the first stack and the second stack. The charge-generating layer can contain an N-type charge-generating layer for supplying an electron to the first stack and a P-type charge-generating layer for supplying a hole to the second stack. The N-type charge-generating layer can contain a metallic material as a dopant. The second stack can be provided on top of the first stack and can be implemented in a structure in which a hole transport layer (HTL), an emission layer (EML(YG)) for yellow-green (YG) and an electron injection layer (EIL) are stacked sequentially. In the display device 100 according to one embodiment of the present disclosure, because the organic light-emitting layer 116 is provided as a common layer, the first stack, the charge generation layer, and the second stack can all be arranged over the multiple subpixels SP. According to another example, the organic light-emitting layer 116 can be provided in a triple-stacked or quadruple-stacked structure, depending on the number of stacked layers. The reflective electrode 117 can be formed on the organic light-emitting layer 116. The reflective electrode 117 can be arranged in the non-display area NDA (or a part of the non-display area NDA) and the display area DA. Within the display area DA, the reflective electrode 117 can be arranged in the light-emitting area EA and the non-light-emitting area NEA (or the first non-light-emitting area NEA1 and the second non-light-emitting area NEA2). That is, the reflective electrode 117 can be arranged to cover the entire display area DA. As a result, the reflective electrode 117 can be arranged such that it has a size that is larger than the display area DA and smaller than the substrate 110. Accordingly, the reflective electrode 117 can be arranged in the non-display area NDA (or a part of the non-display area NDA) and the display area DA. The reflective electrode 117 according to one example can contain a metallic material. The reflective electrode 117 can reflect the light emitted by the organic light-emitting layer 116 in the multiple subpixels SP to a lower surface of the substrate 110. Therefore, the display device 100 according to one embodiment of the present disclosure can be implemented as a bottom-emitting display device. The display device 100 according to one embodiment of the present disclosure is of a downward-emitting type and must reflect light emitted from the light-emitting layer 122 to the substrate 110. Thus, the reflective electrode 117 can be made of a metallic material exhibiting a high reflectivity. The reflective electrode 117 according to one example can be formed from a metallic material exhibiting a high reflectivity, such as silver (Ag), aluminum (Al), a stacked structure (Ti / Al / Ti) of aluminum and titanium, a stacked structure (ITO / Al / ITO) of aluminum and ITO, an Ag alloy, and a stacked structure (ITO / Ag alloy / ITO) of an Ag alloy and ITO. The Ag alloy can be an alloy such as silver (Ag), palladium (Pd), and copper (Cu). The reflective electrode 117 can be described using terms such as...a second electrode, an opposing electrode and a cathode electrode can be expressed. The encapsulation layer 118 is formed on the reflective electrode 117. The encapsulation layer 118 serves to prevent oxygen or moisture from penetrating the organic light-emitting layer 116 and the reflective electrode 117. The encapsulation layer 118 can comprise several layers, each containing at least one inorganic thin layer and at least one organic thin layer. The encapsulation layer 118 can further contain an absorbent material for absorbing moisture or oxygen to enhance its moisture protection. For example, the absorbent material can be a getter. On the other hand, as shown in Fig. 3, the encapsulation layer 118 can be arranged not only in the light-emitting surface EA, but also in the non-light-emitting surface NEA. The encapsulation layer 118 can be arranged between the reflecting electrode 117 and the opposite substrate 200. In the display device 100 according to one embodiment of the present disclosure, the first planarization layer 1131 can be provided such that it has the same refractive index as the second planarization layer 1132. In this case, light emitted by the organic light-emitting layer 116 and directed towards the substrate 110 does not have to be refracted at a boundary between the first planarization layer 1131 and the second planarization layer 1132, but can be emitted towards an outer surface of the substrate 110. However, this is not limited to this, and the first planarization layer 1131 can be provided such that it has a different refractive index than the second planarization layer 1132.In this case, light emitted by the organic light-emitting layer 116 and directed towards the substrate 110 can be refracted at the boundary between the second planarization layer 1132 and the first planarization layer 1131 and can be emitted towards the outside of the substrate 110. An example is given below in which the second planarization layer 1132 has the same refractive index as the first planarization layer 1131. With reference to Fig. 6 and Fig. 7, the display device 100 according to an embodiment of the present disclosure may further comprise a first reflective section 121 and a second reflective section 122. Referring to Fig. 6, the first reflective section 121 can be arranged such that it is inclined in the first non-emissive surface NEA1. By way of example, the first reflective section 121 can be arranged on the second planarization layer 1132 (or an inclined surface 1132b of the second planarization layer 1132) in the first non-emissive surface NEA1. As shown in Fig. 6, since the inclined surface 1132b of the second planarization layer 1132 is arranged such that it is inclined, the first reflective section 121, which is arranged on the inclined surface 1132b of the second planarization layer 1132, can also be arranged such that it is inclined. The first reflective section 121 is formed from a material capable of reflecting light such that light emitted from the light-emitting surface EA and guided by a waveguide can be reflected to the light-emitting subpixel SP. The first reflective section 121 can be formed along a profile of a first pattern section that is concave in the first non-emissive surface NEA1. As illustrated in Fig. 6, the first reflective section 121 is part of the reflective electrode 117 arranged in the first non-emissive surface NEA1 and can thus be designated by the drawing reference numeral 117'. As shown in Fig. 6, the first reflective section 121 can be arranged obliquely in the first non-emissive surface NEA1. Accordingly, the first reflective section 121 can be expressed in terms of an inner reflective section and an inner obliquely reflective section located on the inside of each of the multiple subpixels SP. Therefore, according to an embodiment of the present disclosure, the display device 100 is provided with the reflective section (or the first reflective section 121) which is arranged in the non-light-emitting surface NEA (or the first non-light-emitting surface NEA1) which is provided on the inside of each of the multiple subpixels SP, such that light extraction can be achieved even in the non-light-emitting surface NEA (or the first non-light-emitting surface NEA1) and thus the light yield can be improved. Referring to Fig. 7, the second reflective section 122 can be arranged at an angle in the second non-light-emitting surface NEA2, according to one example. The second reflective section 122 can be arranged at an angle by being positioned on an inclined surface 1132b of the second planarization layer 1132 in the second non-light-emitting surface NEA2. The second reflective section 122 is formed from a material capable of reflecting light such that light emitted from the light-emitting surface EA and guided by a waveguide can be reflected back to the light-emitting surface EA of the light-emitting subpixel SP. The second reflective section 122 can be formed along the profile of a pattern section (or a second pattern section) that is concave in the second non-light-emitting surface NEA2. As shown in Fig.As illustrated in Figure 7, the second reflective section 122 is part of the reflective electrode 117, which is arranged in the second non-emissive surface NEA2, and can therefore be indicated by the drawing symbol 117''. Since the second reflective section 122 is arranged obliquely in the second non-emissive surface NEA2, it can be expressed in terms of an outer reflective section and an outer oblique reflective section located on the outside of each of the multiple subpixels SP. Therefore, according to one embodiment of the present disclosure, the display device 100 is provided with the reflective section (or the second reflective section 122) which is positioned in the non-emissive surface NEA (or the second non-emissive surface NEA2) which is provided on the outside of the multiple subpixels SP, such that light directed towards an adjacent subpixel SP can be reflected by the reflective section (or the second reflective section 122), thereby preventing color mixing and maximizing the light extraction efficiency. As a result, since the display device 100 according to an embodiment of the present disclosure can extract light even in the non-light-emitting area NEA through the reflective sections (or the first reflective section 121 and the second reflective section 122) provided on the inside and outside of each of the multiple subpixels SP, the display device can have the same light emission efficiency or improve the light emission efficiency to a greater extent with lower power compared to a display device that does not have reflective sections on the inside and outside of each of the multiple subpixels, such that the overall power consumption can be reduced. Meanwhile, in the display device 100 according to one embodiment of the present disclosure, a portion of the light emitted by the organic light-emitting layer 116 can be emitted to the outside of the substrate 110 through the first reflective section 121 and the second reflective section 122. Accordingly, the light reflected by each of the first reflective section 121 and the second reflective section 122 and emitted to the substrate 110 can be defined as a reflected light EL. For example, as shown in Fig. 6, some of the light emitted by the organic light-emitting layer 116 can be reflected by the first reflective section 121 provided in the first non-light-emitting surface NEA1 and emitted to the outside of the substrate 110. Accordingly, the reflected light EL, which is reflected and emitted by the first reflective section 121 in the first non-light-emitting surface NEA1, can be defined as a first reflected light EL1. In contrast, as shown in Fig. 7, some of the light emitted by the organic light-emitting layer 116 can be reflected by the second reflective section 122, which is provided in the second non-light-emitting surface NEA2, and emitted to the outside of the substrate 110. Accordingly, the reflected light EL, which is reflected and emitted by the second reflective section 122 in the second non-light-emitting surface NEA2, can be defined as a second reflected light EL2. As a result, the display device 100 according to an embodiment of the present disclosure can improve the light output because light that is quenched by the waveguide can be reflected by the first reflective section 121 in the first non-emissive surface NEA1 and emitted as first reflected light EL1, and light that is quenched by the waveguide can be reflected by the second reflective section 122 in the second non-emissive surface NEA2 and emitted as second reflected light EL2. Referring again to Fig. 6, in the display device 100 according to an embodiment of the present disclosure, the data branch line BRL1 can be arranged on the first repair section RPP1. During a repair process, a laser device can apply a laser pulse LS from the lower section of the substrate 110 to the inner surface of the substrate 110, e.g., the first repair section RPP1 (or the data branch line BRL1). However, if the first repair section RPP1 is not present, the laser pulse LS can affect not only the data branch line BRL1 but also the reflective electrode 117 on the data branch line BRL1, causing damage (or breakage) to the reflective electrode 117.Accordingly, the display device 100 is provided according to an embodiment of the present disclosure such that the data branch line BRL1 is arranged on the first repair section RPP1 in such a way that damage (or breakage) of the reflective electrode 117 is prevented during a repair process using a laser device, while only the data branch line BRL1 can be cut. For the reason described above, the display device 100 can be provided according to an embodiment of the present disclosure such that the reference branch line BRL2 is arranged on the second repair section RPP2. Meanwhile, each of the data branch line BRL1 and the reference branch line BRL2 can be located closer to the substrate 110 than the reflecting electrode 117. Therefore, the laser pulse LS emitted by the laser device during the repair process can have a long wavelength. This is because, if the laser pulse LS has a short wavelength, it could penetrate deep into the substrate 110 and damage the layer E of organic light-emitting elements (e.g., the pixel electrode 114). Therefore, in the display device 100 according to one embodiment of the present disclosure, a long-wavelength laser pulse LS is used in the repair process of each of the data branch line BRL1 and the reference branch line BRL2, such that each of the data branch line BRL1 and the reference branch line BRL2 can be severed while preventing damage to the organic layer E of light-emitting elements.In the present disclosure, the laser pulse LS can be defined using a long wavelength as a first laser pulse LS1 (shown in Fig. 6). Meanwhile, the width RW of the repair section RPP (e.g., a first repair section RPP1) can be narrower than the width NW of the first non-light-emitting surface NEA1. If the width RW of the repair section RPP (e.g., the first repair section RPP1) is equal to or wider than the width NW of the first non-light-emitting surface NEA1, the light reflected by the first reflective section 121 is blocked by the repair section RPP (e.g., the first repair section RPP1) and cannot be emitted to the outside of the substrate 110. Accordingly, the display device 100 according to one embodiment of the present disclosure can have a repair structure, while a reduction in light extraction efficiency by having the width RW of the repair section RPP (e.g.,of the first repair section RPP1), which is narrower than the width NW of the first non-light-emitting surface NEA1, is prevented. The display device 100 according to one embodiment of the present disclosure can include a color filter CF provided between the repair section RPP and the reflecting electrode 117. For example, as shown in Fig. 6, a blue color filter CF2 can be arranged between the repair section RPP and the reflecting electrode 117. Accordingly, the blue color filter CF2 can prevent the laser pulse LS from reaching the reflecting electrode 117 during a repair process. That is, the blue color filter CF2 can have a blocking function that reduces the laser pulse LS. As shown in Fig. 3, the blue subpixel SP3, in which the blue color filter CF2 is arranged, can be located adjacent to the white subpixel SP2. Accordingly, if the blue color filter CF2 is formed in the blue subpixel SP3, the blue color filter CF2 can be easily provided between the repair section RPP and the reflecting electrode 117 without an additional process by also forming the blue color filter CF in the first non-emissive surface NEA1 of the white subpixel SP2. Similarly, the display device 100 according to an embodiment of the present disclosure can have a structural feature wherein the blue color filter CF2 is arranged not only in the blue subpixel SP3, but also in the first non-emissive surface NEA1 of the white subpixel SP2 (or the first non-emissive surface NEA1 that is provided with the repair section RPP of the white subpixel SP2). In the preceding section, the blue color filter CF2 was described as reducing the laser pulse LS; however, it is not limited to this function, and a color filter of a different color or material can be arranged between the repair section RPP and the reflecting electrode 117 if it can reduce (or absorb) the laser pulse LS. For example, a red color filter CF1 or a green color filter CF3 can be arranged between the repair section RPP and the reflecting electrode 117. Alternatively, a material forming a bank 115 can be arranged between the repair section RPP and the reflecting electrode 117. Referring again to Fig. 6, in the display device 100 according to one embodiment of the present disclosure, a width CFW of the color filter CF (or the blue color filter CF2), which is provided between the repair section RPP and the reflecting electrode 117, can be provided such that it is wider than a width RW of the repair section RPP. As described above, the color filter CF (or the blue color filter CF2) serves to reduce (or absorb) the laser pulse LS. Therefore, if the width CFW of the color filter CF (or the blue color filter CF2), which is provided between the repair section RPP and the reflecting electrode 117, is equal to or narrower than the width RW of the repair section RPP, the laser pulse LS can affect the reflecting electrode 117, thereby damaging the reflecting electrode 117.Therefore, in the display device 100 according to an embodiment of the present disclosure, the width CFW of the color filter CF (or the blue color filter CF2) provided between the repair section RPP and the reflective electrode 117 is provided in such a way that it is wider than the width RW of the repair section RPP, such that damage to the reflective electrode 117 during the repair process can be prevented. Additionally, as shown in Fig. 6, if the width CFW of the color filter CF (or the blue color filter CF2) provided between the repair section RPP and the reflective electrode 117 is wider than the width RW of the repair section RPP, light reflected by the first reflective part 121 can pass through the blue color filter CF2 and be emitted to the outside of the substrate 110. Therefore, since the display device 100, according to one embodiment of the present disclosure, can emit blue light from the first non-emissive surface NEA1 of the white subpixel SP2, the image output by the substrate 110 can have a bluish tint. Therefore, the display device 100, according to one embodiment of the present disclosure, can meet the needs of users who desire a bluish tint (or a cool tint). According to one embodiment of the present disclosure, the display device 100 includes the red color filter CF1, which is provided between the repair section RPP and the reflective electrode 117, such that red light can be emitted from the first non-emissive surface NEA1 of the white subpixel SP2, thereby enabling an image output through the substrate 110 to have a yellowish tint (or a warm tint). In this case, the user's requirement for a yellowish tint (or a warm tint) can be met. As a result, the display device 100 according to an embodiment of the present disclosure can implement a color perception that corresponds to color coordinates requested by a user by providing a color filter CF among different color filters in the first non-light-emitting surface NEA1 of the white subpixel SP2. Fig. 8 is a schematic cross-sectional view of a conduit IV-IV' shown in Fig. 3, which shows a cross-sectional view in the first direction (the Y-axis direction) of the red subpixel SP1. The cross-sectional view of the first direction (the Y-axis direction) of the red subpixel SP1 is identical to the cross-sectional view of the first direction (the Y-axis direction) of the white subpixel SP2 of Fig. 6, which was described above, except that the red color filter CF1 is arranged in the course of the first light emission surface EA1, the second light emission surface EA2 and the third light emission surface EA3 and the reference branch line BRL2 is arranged on the second repair section RPP2. Referring to Fig. 8, in the red subpixel SP1, the red color filter CF1 is arranged between the repair section RPP and the reflective electrode 117, such that red light can be emitted from the first non-emissive surface NEA1 of the red subpixel SP1. Accordingly, since the display device 100, according to one embodiment of the present disclosure, can emit red light through the first reflective section 121 and the red color filter CF1 itself in the first non-emissive surface NEA1 of the red subpixel SP1, the light extraction efficiency of the red light need not be reduced, even if the first non-emissive surface NEA1 is provided on the inside of the red subpixel SP1. Meanwhile, in the red subpixel SP1, the red color filter CF1 is arranged between the second repair section RPP2 and the reflecting electrode 117, such that the red color filter CF1 can have a blocking function that reduces a laser pulse LS during the repair process of cutting the reference branch line BRL2. Fig. 9 is a schematic cross-sectional view taken along a line VV' (shown in Fig. 3). Referring to Fig. 9, the display device 100 can be provided according to an embodiment of the present disclosure such that the width RW of the first repair section RPP1 is wider than the width BW of the data branch line BRL1. If the width RW of the first repair section RPP1 is equal to or narrower than the width BW of the data branch line BRL1, the first repair section RPP1 does not need to receive a sufficient laser pulse from the laser device and thus does not need to cut the data branch line BRL1.Accordingly, in the display device 100 according to one embodiment of the present disclosure, the width RW of the first repair section RPP1 is provided such that it is wider than the width BW of the data branch line BRL1, such that during the repair process a sufficient laser pulse can be applied through the first repair section RPP1 to the data branch line BRL1, such that the data branch line BRL1 can be easily cut. For this reason, the display device 100 according to one embodiment of the present disclosure can have a structural feature in which the width RW' of the second repair section RPP2 is wider than the width BW' of the reference branch line BRL2. Referring to Fig. 9, the second connecting section CP2 can be positioned between the first repair section RPP1 and the second repair section RPP2. According to one embodiment of the present disclosure, when a foreign substance is attached to one or two of the first light-emitting surface EA1, the second light-emitting surface EA2 and the third light-emitting surface EA3, the first connecting section CP1 or the second connecting section CP2 is cut by a laser device such that the light-emitting surface (e.g. the first light-emitting surface EA1) to which the foreign substance adheres becomes dark and the remaining light-emitting surfaces (e.g. the second light-emitting surface EA2 and the third light-emitting surface EA3) can be controlled normally (or somewhat darkened).Therefore, to prevent damage to a conductor around the second connection section CP2 (or the first connection section CP1) during the repair process of cutting the second connection section CP2 (or the first connection section CP1), a width CW of the second connection section CP2 (or the first connection section CP1) can be provided such that it is narrower than a width EW of the light-emitting area EA. Therefore, as shown in Fig. 9, the display device 100 according to an embodiment of the present disclosure can have a structural feature wherein the second connection section CP2 is arranged between the first repair section RPP1 and the second repair section RPP2. Since the second interconnection section CP2 is configured to connect to the second light-emitting surface EA2 and the third light-emitting surface EA3, it can have the same structure as either the second light-emitting surface EA2 or the third light-emitting surface EA3. Accordingly, as shown in Fig. 9, the second interconnection section CP2 can contain a layer E of organic light-emitting elements, which includes a pixel electrode 114, an organic light-emitting layer 116, and a reflecting electrode 117. Therefore, the pixel electrode 114 contained in the second interconnection section CP2 can be designated by the symbol 114'. Similarly, the pixel electrode 114 contained in the first interconnection section CP1 can also be designated by the symbol 114'. Meanwhile, as shown in Fig. 3, the first connecting section CP1 can be located relatively farther from the circuit surface CA than the second connecting section CP2. This is because the first connecting section CP1 serves to connect the first light-emitting surface EA1 and the second light-emitting surface EA2, which are located farther from the circuit surface CA than the third light-emitting surface EA3. Accordingly, the first connecting section CP1 does not need to be located between the first repair section RPP1 and the second repair section RPP2. Referring again to Fig. 9, in the display device 100 according to an embodiment of the present disclosure, the first repair section RPP1 or the second repair section RPP2 can be arranged spaced apart from the second connection section CP2 by a first distance. For example, the first repair section RPP1 can be arranged spaced apart from the second connection section CP2 by a first distance D1. The second repair section RPP2 can be arranged spaced apart from the second connection section CP2 by a first distance D1'. The first distance D1 (or the first distance D1') can be a minimum distance that does not affect the first repair section RPP1 (or the second repair section RPP2) during a cutting process of the second connection section CP2. As shown in Fig.As shown in Figure 9, a data branch line BRL1 can be arranged on the first repair section RPP1, and a reference branch line BRL2 can be arranged on the second repair section RPP2. Therefore, if the first repair section RPP1 or the second repair section RPP2 is arranged such that it is spaced from the second connection section CP2 by a distance smaller than the first distance, the laser pulse can also be transmitted to the first repair section RPP1 or the second repair section RPP2, thereby damaging the data branch line BRL1 or the reference branch line BRL2. Therefore, the display device 100 according to an embodiment of the present disclosure can have a structural feature wherein the first repair section RPP1 or the second repair section RPP2 is arranged such that it is spaced from the second connection section CP2 by the first distance. The second connection section CP2 can be severed by the laser pulse LS of the laser device. Therefore, if the first repair section RPP1 (or the second repair section RPP2) is positioned closer to the second connection section CP2 than the first distance D1 (or the first distance D1'), the data branch line BRL1 and / or the reference branch line BRL2 can be severed by being affected by the laser pulse LS. If the data branch line BRL1 and / or the reference branch line BRL2 are severed, the entire light emission area EA connected to the data branch line BRL1 and / or the reference branch line BRL2 cannot be addressed. Therefore, in the display device 100 according to an embodiment of the present disclosure, the first repair section RPP1 or the second repair section RPP2 is spaced apart from the second connection section CP2 by a first distance in the second direction (the X-axis direction) in such a way that damage to the data branch line BRL1 and / or the reference branch line BRL2 during a repair process (or a cutting process) for the second connection section CP2 can be prevented. Meanwhile, as shown in Fig. 9, the second connection section CP2 can be positioned further away from the substrate 110 in the third direction (the Z-axis direction) than the first repair section RPP1 (or the second repair section RPP2). Accordingly, the laser pulse LS through the laser device during the repair process can have a short wavelength. This is because, when the laser pulse LS has a short wavelength, it can penetrate deep into the interior of the substrate 110. Therefore, according to one embodiment of the present disclosure, the display device 100 can cut through the second connection section CP2 using a short-wavelength laser pulse LS during the repair (or cutting) process of the second connection section CP2. In the present disclosure, the laser pulse LS can be used as a second laser pulse LS2 (shown in Fig.9 is shown) be defined. Referring to Fig. 9, a data line DL (e.g., a second data line DL2) can be arranged such that it is separated from the first repair section RPP1 by a second distance D2 in the first non-light-emitting surface NEA1. The second distance D2 can be a minimum distance that does not affect the data line DL during a cutting process of the data branch line BRL1 using the first repair section RPP1. The data branch line BRL1 can be severed by the laser pulse LS of the laser device through the first repair section RPP1. Therefore, if the data line DL (e.g., the second data line DL2) is located closer than the second distance D2 to the first repair section RPP1, the data line DL can be severed by the laser pulse LS. If the data line DL is severed, the entire light emission area EA connected to the severed data line DL cannot be addressed. Therefore, in the display device 100 according to an embodiment of the present disclosure, the data line DL (e.g. the second data line DL2) is arranged such that it is spaced away from the first repair section RPP1 by the second distance D2 in the first non-light-emitting surface NEA1, such that damage to the data line DL during a repair process (or a cutting process) of the data branch line BRL1 using the first repair section RPP1 can be prevented. For the reason described above, the display device 100 can be provided according to an embodiment of the present disclosure in such a way that the reference line RL is arranged such that it is spaced apart from the second repair section RPP2 by a second distance D2' in the first non-light-emitting surface NEA1. With reference to Fig. 9, the display device 100 can be provided according to an embodiment of the present disclosure such that a color filter CF (e.g., a blue color filter CF2) overlaps the second connecting section CP2, the first repair section RPP1, and the second repair section RPP2. For example, as shown in Fig. 9, the color filter CF (e.g., the blue color filter CF2) can be provided such that it covers the first repair section RPP1 and the second repair section RPP2 between the second connecting section CP2 and the substrate 110. As described above, the display device 100, according to one embodiment of the present disclosure, can prevent the entire light-emitting area EA of each subpixel SP from being darkened due to a short circuit between conductors contained in the substrate 110. For example, if a short circuit occurs between conductors, the data branch line BRL1 or the reference branch line BRL2 is cut by the laser pulse LS (or the first laser pulse LS1) that is forwarded to the repair section RPP, thus preventing the entire light-emitting area EA from being darkened. Additionally, according to one embodiment of the present disclosure, the display device 100 can prevent the entire light-emitting area EA of each subpixel SP from being darkened by foreign substances generated during a manufacturing process.For example, it is possible to prevent the first connecting section CP1 (or the second connecting section CP2) from being darkened by cutting the laser pulse LS (or the second laser pulse LS2) of the laser device, thus preventing the entire light emission area EA from being darkened. Therefore, according to one embodiment of the present disclosure, the display device 100 is provided such that the color filter CF (e.g., the blue color filter CF2) overlaps with the second connecting section CP2, the first repair section RPP1, and the second repair section RPP2, such that the color filter CF (e.g., the blue color filter CF2) acts as a barrier that reduces a laser pulse LS, thereby preventing the reflecting electrode 117 from being damaged (or cut) by the laser pulse LS. Fig. 10 is a schematic top view illustrating two pixels of a display device according to an embodiment of the present disclosure. Referring to Fig. 10, the multiple pixels (P) can contain a first pixel P1 and a second pixel P2. For example, the second pixel P2 can be positioned above the first pixel P1 in the first direction (the Y-axis direction). The first pixel P1 can contain a first subpixel SP1, a second subpixel SP2, a third subpixel SP3, and a fourth subpixel SP4, arranged sequentially in the second direction (the X-axis direction). For example, the first subpixel SP1 can be a red subpixel, the second subpixel SP2 can be a white subpixel, the third subpixel SP3 can be a blue subpixel, and the fourth subpixel SP4 can be a green subpixel. The second pixel P2 can contain another first subpixel SP1', another second subpixel SP2', another third subpixel SP3', and another fourth subpixel SP4', arranged sequentially in the second direction (the X-axis direction). For example, the second first subpixel SP1' can be a red subpixel, the second subpixel SP2' can be a white subpixel, the third subpixel SP3' can be a blue subpixel, and the fourth subpixel SP4' can be a green subpixel. Therefore, another first subpixel SP1' of the second pixel P2 can be provided in the first direction (the Y-axis direction) above the first subpixel SP1 of the first pixel P1. Another second subpixel SP2' of the second pixel P2 can be provided in the first direction (the Y-axis direction) above the second subpixel SP2 of the first pixel P1. Another third subpixel SP3' of the second pixel P2 can be provided in the first direction (the Y-axis direction) above the third subpixel SP3 of the first pixel P1. Another fourth subpixel SP4' of the second pixel P2 can be provided in the first direction (the Y-axis direction) above the fourth subpixel SP4 of the first pixel P1. As shown in Fig. 10, each of the first to fourth subpixels SP1, SP2, SP3, SP4 of the first pixel P1 can contain a first light-emitting surface EA1, a first connecting section CP1, a second light-emitting surface EA2, a second connecting section CP2, and a third light-emitting surface EA3. Each of the further first to fourth subpixels SP1', SP2', SP3', SP4' of the second pixel P2 can be provided with the same structure as each of the first to fourth subpixels SP1, SP2, SP3, SP4 of the first pixel P1. The first subpixel SP1 of the first pixel P1 can contain a pixel electrode 114, which is partially located in the first light-emitting surface EA1. Another first subpixel SP1' of a second pixel P2 can contain a circuit surface CA. As shown in Fig. 10, the circuit surface CA of another first subpixel SP1' can be located between a third light-emitting surface EA3 of another first subpixel SP1' and the first light-emitting surface EA1 of the first subpixel SP1. In the display device 100 according to an embodiment of the present disclosure, the substrate 110 can further comprise a weld line WDL. The weld line WDL serves to control the light emission area EA of a subpixel SP in which a line short circuit (e.g., a short circuit in a data line or a short circuit in a reference line) has occurred, together with a light emission area EA of another subpixel SP'. For example, if a short circuit occurs in a data line DL after the data branch line BRL1 has been cut by the first repair section RPP1, the pixel electrode 114 in the subpixel SP where the short circuit occurred and the circuit area CA (or the thin-film transistor 112) in another subpixel SP (e.g., a subpixel SP adjacent to a top surface with reference to Fig. 10) can be connected by a weld path WDL. For example, a pixel electrode 114 in a subpixel SP where a short circuit has occurred can be connected to a circuit area CA (or a thin-film transistor 112) of another subpixel SP' (or another subpixel SP' that is normally driven) by applying a laser pulse to a weld spot WDP in a weld path WDL.Accordingly, the welding path WDL can be connected to the pixel electrode 114 of the subpixel SP and the circuit surface CA of the further subpixel SP'. For example, as shown in Fig. 10, a weld path WDL between a first subpixel SP1 and another first subpixel SP1' can be connected to a pixel electrode 114 of the first subpixel SP1 and a circuit surface CA of another first subpixel SP1'. A weld path WDL between a second subpixel SP2 and another second subpixel SP2' can be connected to a pixel electrode 114 of the second subpixel SP2 and a circuit surface CA of another second subpixel SP2'. A weld path WDL between a third subpixel SP3 and another third subpixel SP3' can be connected to a pixel electrode 114 of the third subpixel SP3 and a circuit surface CA of another third subpixel SP3'.A weld path WDL between a fourth subpixel SP4 and another fourth subpixel SP4' can be connected to a pixel electrode 114 of the fourth subpixel SP4 and a circuit surface CA of another fourth subpixel SP4'. Meanwhile, as shown in Fig. 10, each of several weld lines WDL can contain a weld point WDP that overlaps with a circuit surface CA of another subpixel SP'. For example, a weld line WDL between a first subpixel SP1 and another first subpixel SP1' can contain a weld point WDP that overlaps with a circuit surface CA of another first subpixel SP1'. A weld line WDL between a second subpixel SP2 and another second subpixel SP2' can contain a weld point WDP that overlaps with a circuit surface CA of another second subpixel SP2'. A weld line WDL between a third subpixel SP3 and another third subpixel SP3' can contain a weld point WDP that overlaps with a circuit surface CA of another third subpixel SP3'.A weld path WDL between a fourth subpixel SP4 and another fourth subpixel SP4' can contain a weld point WDP that overlaps with a circuit surface CA of the further fourth subpixel SP1'. Therefore, in the display device 100 according to one embodiment of the present disclosure, after the data branch line BRL1 or the reference branch line BRL2 of the subpixel SP in which a line short circuit (e.g., a short circuit in the data line or a short circuit in the reference line) has occurred has been cut by a laser device, a laser pulse is applied to the weld point WDP such that the pixel electrode 114 of the subpixel SP in which the short circuit occurred and the thin-film transistor 112 of another subpixel SP', which is driven normally, can be connected to each other. Therefore, in the display device 100 according to one embodiment of the present disclosure, the light-emitting surface EA of the subpixel SP in which the short circuit occurred can be driven together with the light-emitting surface EA of the other subpixel SP. The following describes a repair process for a display device 100 according to an embodiment of the present disclosure with reference to Fig. 10. The repair process for a display device 100 according to an embodiment of the present disclosure may include a first repair process by cutting through a connecting section (e.g., a first connecting section CP1 and / or a second connecting section CP2) and a second repair process using a repair section RPP. Referring to Fig. 10, the first repair process can be carried out in various cases as follows. First, for example, in the first case where a foreign substance is generated (or adheres) at position ⓐ (e.g., the first light-emitting surface EA1) of the first subpixel SP1, a laser pulse LS is applied to the first connection segment CP1 to cut through it. This can be achieved by the laser device, which applies a second laser pulse LS2 to the first connection segment CP1. Accordingly, the second light-emitting surface EA2, the second connection segment CP2, and the third light-emitting surface EA3 of the first subpixel SP1 can be addressed normally (or with a slight dimming). Next, for example in the second case, where a foreign substance is generated (or adheres) at position ⓑ of the first subpixel SP1 (e.g., the second light-emitting surface EA2), a laser pulse LS is applied to each of the first connection section CP1 and the second connection section CP2 to cut through them. This can be achieved by the laser device, which applies the second laser pulse LS2 to each of the first connection section CP1 and the second connection section CP2. Next, a laser pulse is applied to a weld point WDP that overlaps with a circuit surface CA of another first subpixel SP1' to connect a pixel electrode 114 in a first light-emitting surface EA1 of the first subpixel SP1 and a thin-film transistor 112 in a circuit surface CA of another first subpixel SP1'. Accordingly, the first light-emitting surface EA1 of the first subpixel SP1 can be addressed together with the light-emitting surface EA of the other first subpixel SP1'. Therefore, the first light-emitting surface EA1 of the first subpixel SP1 can be addressed normally (or slightly dimmed). Next, in the third case, where a foreign substance is generated (or adheres) at the ⓒ position (e.g., the third light-emitting surface EA3) of the first subpixel SP1, a laser pulse LS is applied to the second connection section CP2 to cut through it. This can be achieved by the laser device, which applies the second laser pulse LS2 to the second connection section CP2. Next, a laser beam is applied to a weld point WDP that overlaps with a circuit surface CA of another first subpixel SP1' to connect a pixel electrode 114 in a first light-emitting surface EA1 of the first subpixel SP1 and a thin-film transistor 112 in a circuit surface CA of another first subpixel SP1'. The pixel electrode 114 in the second light-emitting surface EA2 of the first subpixel SP1 can be connected to the pixel electrode 114 in the first light-emitting surface EA1 of the first subpixel SP1 via the pixel electrode 114 in the first connection section CP1 of the first subpixel SP1. Accordingly, the first light-emitting surface EA1, the first connection section CP1, and the second light-emitting surface EA2 of the first subpixel SP1 can be addressed together with the light-emitting surface EA of another first subpixel SP1'. Therefore, in the display device 100 according to an embodiment of the present disclosure, the first repair process is carried out in the first to third cases as described above, thereby preventing the entire light emission area EA of each subpixel SP from being darkened by foreign substances that are generated during the manufacturing process. Referring again to Fig. 10, the second repair process can be carried out in various cases as follows. First, in the fourth case, where a short circuit occurs in the data line DL (e.g., the second data line DL2) of the second subpixel SP2, a laser pulse LS is applied to position ⓓ (e.g., the first repair section RPP1) to cut the data branch line BRL1. This can be achieved by the laser device applying the first laser pulse LS1 to the first repair section RPP1. Next, a laser pulse is applied to a weld point WDP that overlaps with a circuit surface CA of a further second subpixel SP2' to connect a pixel electrode 114 in a first light-emitting surface EA1 of the second subpixel SP2 and a thin-film transistor 112 in a circuit surface CA of a further second subpixel SP2'. The pixel electrode 114 in the second light-emitting surface EA2 of the second subpixel SP2 can be connected to the pixel electrode 114 in the first light-emitting surface EA1 of the second subpixel SP2 via the pixel electrode 114 in the first connection section CP1 of the second subpixel SP2, and the pixel electrode 114 in the third light-emitting surface EA3 of the second subpixel SP2 can be connected to the pixel electrode 114 in the second light-emitting surface EA2 of the second subpixel SP2 via the pixel electrode 114 in the second connection section CP2 of the second subpixel SP2.Accordingly, the first light emission surface EA1, the first connecting section CP1, the second light emission surface EA2, the second connecting section CP2 and the third light emission surface EA3 of the second subpixel SP2 can be controlled together with the light emission surface EA of another second subpixel SP2'. Next, for example in the fifth case, where a short circuit occurs in the reference line RL, a laser pulse LS is applied to position ⓔ (e.g., the second repair section (RPP2)) to cut the reference branch line BRL2. This can be achieved by the laser device, which applies the first laser pulse LS1 to the second repair section RPP2. Next, a laser pulse is applied to a weld point WDP that overlaps with a circuit surface CA of a further second subpixel SP2' to connect a pixel electrode 114 in a first light-emitting surface EA1 of the second subpixel SP2 and a thin-film transistor 112 in a circuit surface CA of a further second subpixel SP2'. The pixel electrode 114 in the second light-emitting surface EA2 of the second subpixel SP2 can be connected to the pixel electrode 114 in the first light-emitting surface EA1 of the second subpixel SP2 via the pixel electrode 114 in the first connection section CP1 of the second subpixel SP2, and the pixel electrode 114 in the third light-emitting surface EA3 of the second subpixel SP2 can be connected to the pixel electrode 114 in the second light-emitting surface EA2 of the second subpixel SP2 via the pixel electrode 114 in the second connection section CP2 of the second subpixel SP2.Accordingly, the first light emission surface EA1, the first connecting section CP1, the second light emission surface EA2, the second connecting section CP2 and the third light emission surface EA3 of the second subpixel SP2 can be controlled together with the light emission surface EA of another second subpixel SP2'. Therefore, in the display device 100 according to an embodiment of the present disclosure, the second repair process is carried out in the fourth and fifth cases described above, thereby preventing the entire light emission area EA of each subpixel SP from becoming dark due to a short circuit between electrodes (or leads). Meanwhile, it has been described above that a welding process is carried out to connect a pixel electrode 114 in a first light emission surface EA1 of a second subpixel SP2, in which a foreign substance is created (or adheres), by applying a laser pulse to a welding point WDP in the second repair process and a thin-film transistor 112 in a circuit surface CA of another second subpixel SP2', but it is not necessarily limited to this. The display device 100 according to one embodiment of the present disclosure need not be provided with a weld track WDL containing a weld point WDP to expand the light-emitting area EA (or aperture ratio) of each of several subpixels SP. In this case, a weak darkening process can be carried out, whereby only the light-emitting area in which a foreign substance has appeared is darkened by cutting the first connection section CP1 or the second connection section CP2, and the remaining light-emitting areas are operated normally. When the weak darkening process is carried out, some light-emitting areas of a subpixel cannot be driven, which is why a current density of the remaining light-emitting areas that are driven normally can increase.Therefore, an additional compensation process can be carried out by supplying a reduced data voltage to the subpixel SP where the weak darkening process is carried out, compared to the subpixel SP that is normally controlled. Embodiments of the present disclosure have been described in more detail with reference to the accompanying drawings; however, the present disclosure is not necessarily limited to these embodiments and can be implemented in various modifications without deviating from the technical concepts of the present disclosure. Accordingly, the embodiments disclosed herein are intended to illustrate, not to limit, the technical concepts of the present disclosure, and the scope of the technical concepts of the present disclosure is not limited by these embodiments. Therefore, the embodiments described above are in every respect exemplary and should be understood as non-limiting. All technical concepts within the scope of protection of this disclosure shall be interpreted as being included within the scope of the claims of this disclosure. The display device according to the present disclosure can extend or increase the size (or area) of the light-emitting surface by having the repair section arranged in a non-light-emitting surface (or a first non-light-emitting surface) provided inside each of several subpixels. The display device according to the present disclosure can have an improved luminous efficacy due to the enlargement of the size (or area) of the light-emitting surface. The display device according to the present disclosure can be provided with the reflective section (or the first reflective section) arranged in the non-light-emitting surface (or the first non-light-emitting surface) provided on the inside of each of the multiple subpixels, such that the light extraction efficiency of light emitted by the layer of light-emitting elements can be improved. The display device according to the present disclosure can be provided with the reflective section (or the second reflective section) arranged in the non-light-emitting surface (or the second non-light-emitting surface) provided on the outside of the multiple subpixels, such that the reflective section (or the second reflective section) can reflect light directed towards an adjacent subpixel, thereby maximizing the light extraction efficiency. In some embodiments, each subpixel in the display area can contain multiple light-emitting surfaces. For example, a first light-emitting surface EA1 and a second light-emitting surface EA2 can be arranged adjacent to each other in a single subpixel. A connecting section (e.g., CP1, CP2) can be located between the first and second light-emitting surfaces and can connect the two electrically or structurally. In a top view, the connecting section can appear as a narrower area connecting wider emission zones. A first non-light-emitting surface NEA1 can extend into the space between the first light-emitting surface EA1 and the second light-emitting surface EA2 and can be recessed or sunken relative to the peripheries of these emission surfaces when viewed from above (e.g., a top view or a top view).In such a layout, the first non-light-emitting surface NEA1 can be at least partially surrounded by the first and second light-emitting surfaces and the connecting section in the same plan view. A repair section RPP can be arranged in the first non-light-emitting surface NEA1 to allow for electrical isolation or repair. Each subpixel can contain a stacked structure formed on a substrate, comprising a planarization layer, a pixel electrode arranged on the planarization layer, an organic light-emitting layer arranged on the pixel electrode, and a reflective electrode arranged above the organic light-emitting layer. In some embodiments, the reflective electrode can extend uninterrupted across the emission and non-emission surfaces (e.g., continuously and coherently). A first reflective section 121 of the reflective electrode can be arranged on an inclined surface of the planarization layer in the first non-emission surface. The inclination can be configured to redirect light emitted through the adjacent emission surfaces to the substrate, thereby increasing the light extraction efficiency.A second non-emissive surface can be arranged between adjacent subpixels and can be connected to the first non-emissive surface. A second reflective section 122 of the reflective electrode can be arranged on an inclined surface of the second non-emissive surface and can be positioned to direct light to the substrate. In certain embodiments, the reflective electrode can be formed as a continuous and contiguous thin layer extending across the first and second light-emitting surfaces, the first non-emitting surface, and the second non-emitting surface. This continuous structure can simplify manufacturing and improve optical uniformity. A color filter CF can be positioned over the repair section and between the repair section and the reflective electrode. The color filter CF can extend laterally beyond the boundaries of the repair section and can provide thermal or optical shielding during laser repair. For example, the color filter CF can be configured to absorb laser energy used to interrupt a short circuit between a data branch line and a reference branch line.The data branch line and the reference branch line can be spaced apart and routed into each subpixel, overlapping with a respective first and second repair section located in the first non-emissive surface. In some configurations, the first repair section RPP1 can overlap at least partially with the data branch line, while the second repair section RPP2 can overlap at least partially with the reference branch line, as can be seen in a top view. These overlapping areas can be designed to serve as laser access points for isolating short circuits. Additionally, to maintain electrical continuity after a disconnection, a weld path WDL can be formed between a pixel electrode in a first subpixel and a circuit area in a second subpixel. The circuit area can contain a thin-film transistor or similar driver component. The weld path can include a weld spot, which may be located near the circuit area and may overlap with a boundary of the circuit area in a top view (see Fig. 10).The weld point can serve as the location for building an electrical bridge between the subpixels during a repair after manufacturing. Since the display device according to the present disclosure can extract light even in the non-light-emitting area through the reflective sections (or the first reflective section and the second reflective section) provided on the inside and outside of each of the multiple subpixels, the display device can have the same luminous efficacy or can have a luminous efficacy improved to a higher degree, even with lower power consumption, compared to a display device that does not have reflective sections on the inside and outside of each of the multiple subpixels, such that the overall power consumption can be reduced. The effects to be obtained from the present disclosure are not limited to those mentioned above, and further effects not mentioned will be apparent to a person skilled in the art from the description. The various embodiments described above can be combined to provide further embodiments. These and other modifications can be made to the embodiments in light of the detailed description set forth above. In general, the terms used in the following claims are not to be interpreted as limiting the claims to the specific embodiments disclosed in the application and the claims themselves, but rather as encompassing all possible embodiments together with the full range of correspondences to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
