Each of the plurality of unit areas includes first to fourth sub-areas, and each of the first to fourth sub-areas includes a first color light-emitting area, a second color light-emitting area, and a third color light-emitting area. In each of the first to fourth sub-areas, the third color light-emitting area is disposed on one side in a first direction from the first color light-emitting area and the second color light-emitting area, and the first color light-emitting area is aligned with the second color light-emitting area in a second direction intersecting the first direction. The first sub-region and the second sub-region are aligned in the second direction, the third sub-region and the fourth sub-region are aligned in the second direction, the third sub-region is disposed on one side of the first direction from the first sub-region, and the fourth sub-region is disposed on one side of the first direction from the second sub-region.

A fifth single line area is defined in the second line component disposed between the first color light emitting area of ​​the third sub-region and the second color light emitting area of ​​the third sub-region so as to correspond to the first unit area, and a sixth single line area is defined in the first line component disposed between the second color light emitting area of ​​the third sub-region and the third color light emitting area of ​​the third sub-region so as to correspond to the first unit area. A seventh single line area is defined in the second line component arranged between the first color emission area of ​​the fourth sub-area and the second color emission area of ​​the fourth sub-area to correspond to the first unit area, and an eighth single line area is defined in the first line component arranged between the second color emission area of ​​the fourth sub-area and the third color emission area of ​​the second sub-area to correspond to the first unit area.

[0005] The third color light-emitting area of ​​the first sub-area and the third color light-emitting area of ​​the second sub-area are commonly arranged in the third opening area.

[0006] The third opening area in which the third color light-emitting area of ​​the third sub-area is arranged and the third opening area in which the third color light-emitting area of ​​the fourth sub-area is arranged are different opening areas.

[0007] The line width of the second line component arranged between the third color light emitting area of ​​the third sub-region and the third color light emitting area of ​​the fourth sub-region is greater than the line width of the second line component arranged between the second color light emitting area of ​​the third sub-region and the first color light emitting area of ​​the fourth sub-region.

[0008] The line width of the second line component arranged between the second color light-emitting area of ​​the third sub-region and the first color light-emitting area of ​​the fourth sub-region is substantially the same as the line width of the second line component arranged between the first color light-emitting area of ​​the third sub-region and the second color light-emitting area of ​​the third sub-region.

[0009] A first interval between the third color light-emitting area of ​​the first sub-region and the third color light-emitting area of ​​the second sub-region is smaller than a second interval between the third color light-emitting area of ​​the third sub-region and the third color light-emitting area of ​​the fourth sub-region.

[0010] The sensing electrodes include a first sensing electrode and a second sensing electrode that are arranged adjacently. Between the first sensing electrode and the second sensing electrode, the terminals of the line components of the first sensing electrode and the terminals of the line components of the second sensing electrode are spaced apart from each other to define a boundary disconnection region. At least one of the first to eighth disconnection regions is the boundary disconnection region between the first sensing electrode and the second sensing electrode.

[0011] The above plurality of unit areas include a second unit area different from the first unit area, and the first to eighth single-line areas are defined in the line component to correspond to the first unit area, and single-line areas having a different arrangement from the first to eighth single-line areas are defined in the line component to correspond to the second unit area.

[0012] The first color light-emitting area has a smaller area than the second color light-emitting area, and the third color light-emitting area has a larger area than the second color light-emitting area.

[0013] The above line component includes a first metal layer and a second metal layer disposed on the first metal layer, wherein the first metal layer has a higher electrical conductivity and a higher reflectivity than the second metal layer.

[0014] According to one embodiment of the present invention, a display panel including a plurality of unit areas and an input sensor disposed on the display panel, the input sensor including a first detection electrode and a second detection electrode. Each of the plurality of unit areas includes a first sub-area to a fourth sub-area, and each of the first sub-area to the fourth sub-area includes a first color light-emitting area, a second color light-emitting area, and a third color light-emitting area. In each of the first to fourth sub-areas, the third color light-emitting area is disposed on one side in a first direction from the first color light-emitting area and the second color light-emitting area, and the first color light-emitting area is aligned with the second color light-emitting area in a second direction orthogonal to the first direction. The first sub-region and the second sub-region are aligned in the second direction, the third sub-region and the fourth sub-region are aligned in the second direction, the third sub-region is disposed on one side of the first direction from the first sub-region, and the fourth sub-region is disposed on one side of the first direction from the second sub-region. Each of the first sensing electrode and the second sensing electrode includes a line component defining a first aperture region, a second aperture region, and a third aperture region corresponding to the first color light-emitting region, the second color light-emitting region, and the third color light-emitting region, respectively. The line component includes first line components extending in the second direction and second line components extending in the first direction. A single line region is defined in at least one of the two first line components arranged on both sides of the first color light-emitting region among the first line components of each of the first sensing electrode and the second sensing electrode and in at least one of the two second line components arranged on both sides of the first color light-emitting region among the second line components.Among the first line components of each of the first detection electrode and the second detection electrode, one of the two first line components arranged on both sides of the first color light-emitting area does not have a single line region defined, and among the two second line components of the second line components arranged on both sides of the first color light-emitting area does not have a single line region defined.

[0015] The third color light-emitting area of ​​the first sub-region and the third color light-emitting area of ​​the second sub-region are commonly arranged within the third opening area.

[0016] The third opening area in which the third color light-emitting area of ​​the third sub-area is arranged and the third opening area in which the third color light-emitting area of ​​the fourth sub-area is arranged are different opening areas.

[0017] The line width of the second line component arranged between the third color light emitting area of ​​the third sub-region and the third color light emitting area of ​​the fourth sub-region is greater than the line width of the second line component arranged between the second color light emitting area of ​​the third sub-region and the first color light emitting area of ​​the fourth sub-region.

[0018] The line width of the second line component arranged between the second color light-emitting area of ​​the third sub-region and the first color light-emitting area of ​​the fourth sub-region is substantially the same as the line width of the second line component arranged between the first color light-emitting area of ​​the third sub-region and the second color light-emitting area of ​​the third sub-region.

[0019] A first interval between the third color light-emitting area of ​​the first sub-region and the third color light-emitting area of ​​the second sub-region is smaller than a second interval between the third color light-emitting area of ​​the third sub-region and the third color light-emitting area of ​​the fourth sub-region.

[0020] Between the first detection electrode and the second detection electrode, the terminal of the line component of the first detection electrode and the terminal of the line component of the second detection electrode are spaced apart to define a boundary short-circuit region.

[0021] Between the first detection electrode and the second detection electrode, two second line components of the first detection electrode, which are arranged on both sides of the first color emission region, and two second line components of the second detection electrode, which are arranged on both sides of the first color emission region, are spaced apart from each other to define two boundary single-line regions.

[0022] The two second line components arranged on both sides of the first color emission region of the first sensing electrode defining the above-described boundary short-circuit regions have substantially the same length as the second line component arranged on one side of the short-circuited first color emission region defining the first sensing electrode.

[0023] Between the first sensing electrode and the second sensing electrode, two first line components of the first sensing electrode, which are arranged on both sides of the third color emission region, are spaced apart from the second sensing electrode to define two boundary single-line regions.

[0024] According to the present invention, since the short-circuit regions are arranged in a predetermined order within the sensing electrodes, the phenomenon of the boundary region between the sensing electrodes being clearly visible can be reduced. This is because the amount of external light reflected by the boundary region and the sensing electrode is similar.

[0025] Based on each of the light-emitting regions, a line component extending in the first direction and a line component extending in the second direction are respectively arranged. Therefore, the current flow in the first or second direction of the detection electrode can be smooth.

[0041] Additionally, terms such as "below," "lower," "above," and "upper" are used to describe the relationships between components depicted in the drawings. These terms are relative concepts and are explained based on the directions indicated in the drawings.

[0042] It should be understood that terms such as "include" or "have" are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but do not preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0043] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. Furthermore, terms defined in commonly used dictionaries should be interpreted to have a meaning consistent with their meaning in the relevant technical context, and should not be interpreted in an overly idealistic or overly formal sense unless explicitly defined herein.

[0044] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0045] Fig. 1 is a perspective view of a display device (DD) according to one embodiment of the present invention. As illustrated in Fig. 1, the display device (DD) can display an image through a display surface (DD-IS). The display surface (DD-IS) is parallel to a plane defined by a first direction (DR1) and a second direction (DR2). The normal direction of the display surface (DD-IS), i.e., the thickness direction of the display device (DD), is indicated by a third direction (DR3).

[0046] The front (or upper surface) and the back (or lower surface) of each member or unit described below are distinguished by a third direction (DR3). However, the first to third directions (DR1, DR2, DR3) illustrated in this embodiment are merely examples.

[0047] In one embodiment of the present invention, a display device (DD) having a flat display surface is illustrated, but the present invention is not limited thereto. The display device (DD) may include a curved display surface or a three-dimensional display surface. The three-dimensional display surface may include a plurality of display areas pointing in different directions, and may include, for example, a bended display surface. The display device (DD) according to the present embodiment may be a flexible display device (DD). The flexible display device (DD) may be a foldable display device capable of being folded.

[0048] In this embodiment, a display device (DD) applicable to a tablet terminal is exemplarily illustrated. Electronic modules, a camera module, a power module, etc. mounted on a main board can be arranged together with the display device (DD) in a bracket / case, etc. to form a tablet terminal. The display device (DD) according to the present invention can be applied to large electronic devices such as televisions and monitors, as well as small and medium-sized electronic devices such as cell phones, car navigation systems, game consoles, smart watches, etc.

[0049] As illustrated in Fig. 1, the display surface (DD-IS) includes an image area (DD-DA) where an image is displayed and a bezel area (DD-NDA) adjacent to the image area (DD-DA). The bezel area (DD-NDA) is an area where no image is displayed. Icon images are illustrated in Fig. 1 as examples of images.

[0050] As illustrated in Fig. 1, the image area (DD-DA) may be substantially rectangular. The term "substantially rectangular" includes not only a rectangular shape in the mathematical sense, but also a rectangular shape in which no vertices are defined in the vertex area (or corner area) but the boundary of a curve is defined.

[0051] The bezel area (DD-NDA) may surround the image area (DD-DA). However, this is not limited to this, and the shape of the bezel area (DD-NDA) may be modified. For example, the bezel area (DD-NDA) may be positioned on only one side of the image area (DD-DA).

[0052] FIG. 2 is a cross-sectional view of a display device (DD) according to one embodiment of the present invention.

[0053] The display device (DD) may include a display module (DM) and a window (WM) disposed on the display module (DM). The display module (DM) and the window (WM) may be joined by an adhesive layer (PSA). According to one embodiment of the present invention, the window (WM) may be formed by a coating method and may be in contact with the display module (DM), and in this case, the adhesive layer (PSA) may be omitted.

[0054] A display module (DM) may include a display panel (100), an input sensor (200), and an anti-reflection layer (300). The display panel (100) may include a base layer (110), a driving element layer (120), a light-emitting element layer (130), and an encapsulating layer (140).

The base layer (110) may be a flexible substrate capable of bending, folding, rolling, etc. The base layer (110) may be a glass substrate, a metal substrate, a polymer substrate, etc. However, the embodiment of the present invention is not limited thereto, and the base layer (110) may be an inorganic layer, an organic layer, or a composite material layer. In fact, the base layer (110) has the same shape as the display panel (100).

[0056] The base layer (110) may have a multilayer structure. For example, the base layer (110) may include a first synthetic resin layer, a second synthetic resin layer, and inorganic layers disposed therebetween. Each of the first and second synthetic resin layers may include a polyimide-based resin, but is not particularly limited thereto.

[0057] The driving element layer (120) may be disposed on the base layer (110). The driving element layer (120) may include a plurality of insulating layers, a plurality of semiconductor patterns, a plurality of conductive patterns, signal lines, etc. The driving element layer (120) may include a driving circuit of a pixel.

[0058] The light-emitting element layer (130) may be disposed on the driving element layer (120). The light-emitting element layer (130) may include a light-emitting element. For example, the light-emitting element may include an organic light-emitting material, an inorganic light-emitting material, an organic-inorganic light-emitting material, a quantum dot, a quantum rod, a micro LED, or a nano LED.

[0059] The encapsulating layer (140) may be disposed on the light-emitting element layer (130). The encapsulating layer (140) may protect the light-emitting element layer (130), i.e., the light-emitting element, from foreign substances such as moisture, oxygen, and dust particles. The encapsulating layer (140) may include at least one encapsulating inorganic layer. The encapsulating layer (140) may include a laminated structure of a first encapsulating inorganic layer / encapsulating organic layer / second encapsulating inorganic layer.

[0060] The input sensor (200) may be directly disposed on the display panel (100). The input sensor (200) may detect a user's input, for example, by electromagnetic induction and / or electrostatic capacitance. The display panel (100) and the input sensor (200) may be formed through a continuous process. Here, "directly disposed" may mean that no third component is disposed between the input sensor (200) and the display panel (100). For example, a separate adhesive layer may not be disposed between the input sensor (200) and the display panel (100).

[0061] The anti-reflection layer (300) reduces the reflectivity of external light incident from the upper side of the window (WM). The anti-reflection layer (300) according to one embodiment of the present invention may include a phase retarder and a polarizer.

The arrangement of the color filters of the plurality of groups distinguished by color may be determined by considering the arrangement of the pixels of the plurality of groups distinguished by the emission color. The anti-reflection layer (300) may further include a black matrix adjacent to the color filters. The anti-reflection layer (300) including the color filters may be directly disposed on the display panel (100).

The base layer may include a glass substrate and / or a synthetic resin film, etc. The light-shielding pattern partially overlaps the base layer (WP-BS). The light-shielding pattern is arranged on the back surface of the base layer, and the light-shielding pattern may substantially define a bezel area (DD-NDA, see FIG. 1) of the display device (DD). An area where the light-shielding pattern is not arranged may define an image area (DD-DA, see FIG. 1) of the display device (DD).

Each of the pixels (PX) includes a light-emitting element, and the light-emitting areas (LA1, LA2, LA3) may be areas where light formed by the light-emitting element is emitted. The arrangement relationship between the light-emitting areas (LA1, LA2, LA3) and the non-light-emitting area (NLA) will be described later with reference to Fig. 5.

[0074] The light-emitting areas (LA1, LA2, LA3) can be divided into multiple groups distinguished by light-emitting colors.

In the present embodiment, the first color light can be red light, the second color light can be green light, and the third color light can be blue light.

[0075] The areas of the first color emission area (LA1), the second color emission area (LA2), and the third color emission area (LA3) may be different from each other, but are not necessarily limited thereto. In the present embodiment, the area of ​​the first color emission area (LA1) may be the smallest, and the area of ​​the third color emission area (LA3) may be the largest.

[0076] The first color light-emitting areas (LA1), the second color light-emitting areas (LA2), and the third color light-emitting areas (LA3) can be arranged according to a predetermined rule. The unit area (UA) is a repetitive arrangement unit of the first internal third color light-emitting areas (LA1, LA2, LA3) arranged in the display area (100-DA). In the present embodiment, the unit area (UA) can include a first sub-area (UA1), a second sub-area (UA2), a third sub-area (UA3), and a fourth sub-area (UA4).

The relative arrangement of the first color light-emitting area (LA1) and the second color light-emitting area (LA2) with respect to the third color light-emitting area (LA3) in each of the first sub-region (UA1), the second sub-region (UA2), the third sub-region (UA3), and the fourth sub-region (UA4) may be substantially the same as described below.

[0079] In each of the first sub-area (UA1), the second sub-area (UA2), the third sub-area (UA3), and the fourth sub-area (UA4), the third color light-emitting area (LA3) is arranged on one side of the first color light-emitting area (LA1) and the second color light-emitting area (LA2) in the first direction (DR1). As in Fig. 4a, the third color light-emitting area (LA3) may be arranged on the right side of the first color light-emitting area (LA1) and the second color light-emitting area (LA2).

[0080] In each of the first sub-area (UA1), the second sub-area (UA2), the third sub-area (UA3), and the fourth sub-area (UA4), the first color emitting area (LA1) can be aligned with the second color emitting area (LA2) in the second direction (DR2). In other words, the center point of the first color emitting area (LA1) and the center point of the second color emitting area (LA2) can be located on an imaginary line extending in the second direction (DR2).

[0081] The first sub-region (UA1) and the second sub-region (UA2) can be aligned in the second direction (DR2), and the third sub-region (UA3) and the fourth sub-region (UA4) can be aligned in the second direction (DR2). The third sub-region (UA3) is arranged on one side (right side in FIG. 4A) of the first direction (DR1) from the first sub-region (UA1), and the fourth sub-region (UA4) is arranged on one side (right side in FIG. 4A) of the first direction (DR1) from the second sub-region (UA2).

[0082] The first sub-region (UA1) and the second sub-region (UA2) have different positions of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2). Referring to the first sub-region (UA1), the positions of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2) are arranged relatively lower. Referring to the second sub-region (UA2), the positions of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2) are arranged relatively upper. The first sub-area (UA1) and the second sub-area (UA2) may have different shifting degrees of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2). In the present embodiment, the third color light-emitting area (LA3) of the second sub-area (UA2) may be relatively more shifted. However, the present invention is not limited thereto, and the first sub-area (UA1) and the second sub-area (UA2) may have the same shifting degrees of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2).

[0083] In the present embodiment, the third sub-region (UA3) may have an arrangement of first to third color light-emitting areas (LA1 to LA3) that is substantially the same as that of the second sub-region (UA2), and the fourth sub-region (UA4) may have an arrangement of first to third color light-emitting areas (LA1 to LA3) that is substantially the same as that of the first sub-region (UA1). The first sub-region (UA1) and the fourth sub-region (UA4) may have the same degree of shift of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2). The second sub-region (UA2) and the third sub-region (UA3) may have the same degree of shift of the third color light-emitting area (LA3) with respect to the first color light-emitting area (LA1) and the second color light-emitting area (LA2) within the second direction (DR2).

[0084] The third color light-emitting area (LA3) of the first sub-area (UA1) within the unit area (UA) and the third color light-emitting area (LA3) of the second sub-area (UA2) are spaced apart from each other by a first interval (DT1) and are arranged relatively close to each other. The third color light-emitting area (LA3) of the first sub-area (UA1) and the third color light-emitting area (LA3) of the second sub-area (UA2) spaced apart from each other by the first interval (DT1) define a light-emitting area pair (UP) within the unit area (UA).

[0085] The third color light-emitting area (LA3) of the third sub-area (UA3) within the unit area (UA) and the third color light-emitting area (LA3) of the fourth sub-area (UA4) are spaced relatively far apart from each other by a second interval (DT2). The second interval (DT2) is larger than the first interval (DT1).

[0086] A third color light-emitting area (LA3) of a third sub-area (UA3) of one unit area (UA) can define a light-emitting area pair (UP) with a third color light-emitting area (LA3) of a fourth sub-area (UA4) of another unit area (UA) disposed in a different pixel row (PXR) and the same pixel column (PXC). As illustrated in FIG. 4A, a third color light-emitting area (LA3) of a third sub-area (UA3) of one unit area (UA) can define a light-emitting area pair (UP) with a third color light-emitting area (LA3) of a fourth sub-area (UA4) of a unit area (UA) disposed above. A third color emitting area (LA3) of a fourth sub-area (UA4) of one unit area (UA) defines a emitting area pair (UP) with a third color emitting area (LA3) of a third sub-area (UA3) of another unit area (UA) disposed in a different pixel row (PXR) and the same pixel column (PXC). As illustrated in FIG. 4A, a third color emitting area (LA3) of a fourth sub-area (UA4) of one unit area (UA) can define a emitting area pair (UP) with a third color emitting area (LA3) of a third sub-area (UA3) of a unit area (UA) disposed below.

[0087] As described above, the reason why the light-emitting region pairs (UP) are defined is because the arrangement of the sub-regions (UA1 to UA4) differs depending on the pixel rows (PXR). This is because when the first sub-region (UA1) and the third sub-region (UA3) are alternately arranged along the first direction (DR1) within the odd-numbered pixel rows (PXR), the second sub-region (UA2) and the fourth sub-region (UA4) are alternately arranged along the first direction (DR1) within the even-numbered pixel rows (PXR).

[0088] The reason for forming the light-emitting area pairs (UP) is due to the mask used during deposition. Using the deposition mask, a light-emitting layer having an integral shape is formed on the light-emitting element arranged in the third color light-emitting area (LA3) of the first sub-area (UA1) and the light-emitting element arranged in the third color light-emitting area (LA3) of the second sub-area (UA2). That is, the light-emitting layer arranged in the third color light-emitting area (LA3) of the first sub-area (UA1) and the light-emitting layer arranged in the third color light-emitting area (LA3) of the second sub-area (UA2) have an integral shape. Openings corresponding to the light-emitting area pairs (LP) are defined in the deposition mask. The area between the openings of the deposition mask corresponds to the blocking area of ​​the deposition mask. By defining the openings corresponding to the light-emitting area pairs (LP), the number of openings is reduced, and the width of the blocking area of ​​the deposition mask arranged between the openings in the second direction (DR2) can be secured. Thin deposition masks require a sufficiently wide shielding area within the second direction (DR2) to prevent sagging defects during the deposition process. Furthermore, masks with fewer openings are easier to produce and can reduce mask defects.

[0089] This can be seen by comparing the third spacing (DT3) between the third color emission areas (LA3) illustrated in FIG. 4B. Referring to FIG. 4B, one type of unit area (UA) is arranged in the display area (100-DA). The third spacing (DT3) between the third color emission areas (LA3) of adjacent unit areas (UA) of the pixel column (PXC) is smaller than the second spacing (DT2) illustrated in FIG. 4B. The deposition mask used to form the third color emission areas (LA3) of FIG. 4B includes a larger number of openings than the deposition mask described with reference to FIG. 4A, since openings are arranged for each of the third color emission areas (LA3). Therefore, the width of the blocking area of ​​the deposition mask having a larger number of openings is relatively reduced. This is because openings corresponding to the third color emission areas (LA3) are defined in the mask for forming emission layers in the third color emission areas (LA3) illustrated in FIG. 4B.

[0090] Fig. 5 is a cross-sectional view of a display device (DD) corresponding to line I-I' of Fig. 4a. In Fig. 5, some components of the display device (DD), such as the anti-reflection layer (300) and the window (WM) of Fig. 2, are not shown.

In Fig. 5, a silicon transistor (S-TFT) and an oxide transistor (O-TFT) are illustrated as examples of transistors. The pixel driving circuit (PC) of Fig. 5 is merely an embodiment, and the configuration of the pixel driving circuit (PC) is not necessarily limited thereto. The pixel driving circuit (PC) may include only one type of transistor among the silicon transistor (S-TFT) and the oxide transistor (O-TFT).

[0092] Referring to FIG. 5, the base layer (110) is illustrated as a single layer. The base layer (110) may include a synthetic resin such as polyimide. The base layer (110) may be formed by coating a synthetic resin layer on a working substrate (or carrier substrate). When the display module (DM) is completed through a subsequent process, the working substrate may be removed.

The buffer layer (10bf) may include at least one inorganic layer. The buffer layer (10bf) may include a silicon oxide layer and a silicon nitride layer.

[0096] A first semiconductor pattern (SC1) may be arranged on the buffer layer (10bf). The first semiconductor pattern (SC1) may include a silicon semiconductor. For example, the silicon semiconductor may include amorphous silicon, polycrystalline silicon, etc. For example, the first semiconductor pattern (SC1) may include low-temperature polysilicon.

[0097] The first semiconductor pattern (SC1) may have different electrical properties depending on whether it is doped. The first semiconductor pattern (SC1) may include a first region having high conductivity and a second region having low conductivity. The first region may be doped with an N-type dopant or a P-type dopant. The second region may be an undoped region or a region doped at a lower concentration than the first region. A source region (SE1), a channel region (AC1, or active region), and a drain region (DE1) of a silicon transistor (S-TFT) may be formed from the first semiconductor pattern (SC1). The source region (SE1) and the drain region (DE1) may extend in opposite directions from the channel region (AC1) in a cross-section.

The first insulating layer (10) may be an inorganic layer. Not only the first insulating layer (10), but also the inorganic layer of the driving element layer (120) described below may have a single-layer or multi-layer structure and may include at least one of the materials described above, but is not limited thereto.

[0099] A gate (GT1) of a silicon transistor (S-TFT) is disposed on a first insulating layer (10). The gate (GT1) may be a part of a metal pattern. The gate (GT1) overlaps a channel region (AC1). In a process of doping the first semiconductor pattern (SC1), the gate (GT1) may be a mask. A first electrode (CE10) of a storage capacitor (Cst) is disposed on the first insulating layer (10). On a plane, the first electrode (CE10) may have an integral shape with the gate (GT1).

[0100] A second insulating layer (20) is disposed on the first insulating layer (10) and can cover the gate (GT1).

[0101] A second shielding electrode (BMLb) is disposed on the second insulating layer (20). The second shielding electrode (BMLb) may be disposed to correspond to an oxide transistor (O-TFT). In one embodiment of the present invention, the second shielding electrode (BMLb) may be omitted. A third insulating layer (30) may be disposed on the second insulating layer (20). A second semiconductor pattern (SC2) may be disposed on the third insulating layer (30). The second semiconductor pattern (SC2) may include a channel region (AC2) of the oxide transistor (O-TFT).

[0102] A metal oxide semiconductor may include a plurality of regions (SE2, AC2, DE2) distinguished depending on whether a transparent conductive oxide is reduced. A region where the transparent conductive oxide is reduced (hereinafter, referred to as a reduced region) has greater conductivity than a region where it is not reduced (hereinafter, referred to as a non-reduced region). The reduced region substantially functions as a source / drain or signal line of the transistor. The non-reduced region substantially corresponds to a semiconductor region (or channel) of the transistor. A fourth insulating layer (40) may be disposed on the third insulating layer (30). As illustrated in FIG. 5, the fourth insulating layer (40) may cover the second semiconductor pattern (SC2).

[0103] A gate (GT2) of an oxide transistor (O-TFT) is disposed on a fourth insulating layer (40). The gate (GT2) of the oxide transistor (O-TFT) may be a part of a metal pattern. The gate (GT2) of the oxide transistor (O-TFT) overlaps the channel region (AC2). A fifth insulating layer (50) is disposed on the fourth insulating layer (40), and the fifth insulating layer (50) may cover the gate (GT2). Each of the first insulating layer (10) to the fifth insulating layer (50) may be an inorganic layer.

[0104] The first connection pattern (CNP1) and the second connection pattern (CNP2) may be disposed on the fifth insulating layer (50). Since the first connection pattern (CNP1) and the second connection pattern (CNP2) are formed through the same process, they may have the same material and the same laminated structure. The first connection pattern (CNP1) may be connected to the drain region (DE1) of the silicon transistor (S-TFT) through the first pixel contact hole (PCH1) penetrating the first to fifth insulating layers (10, 20, 30, 40, 50). The second connection pattern (CNP2) may be connected to the source region (SE2) of the oxide transistor (O-TFT) through the second pixel contact hole (PCH2) penetrating the fourth and fifth insulating layers (40, 50).

A data line (DL) may be disposed on the sixth insulating layer (60). The seventh insulating layer (70) may be disposed on the sixth insulating layer (60) and may cover the third connection pattern (CNP3) and the data line (DL). Since the third connection pattern (CNP3) and the data line (DL) are formed through the same process, they may have the same material and the same laminated structure. Each of the sixth insulating layer (60) and the seventh insulating layer (70) may be an organic layer.

[0106] A light emitting element (LD) may include an anode (AE, or first electrode), a light emitting layer (EL), and a cathode (CE, or second electrode). The anode (AE) of the light emitting element (LD) may be disposed on a seventh insulating layer (70). The anode (AE) may be a (semi)transparent electrode or a reflective electrode.

The black coloring agent may include a metal such as chromium, an oxide thereof, or carbon black. The pixel defining layer (PDL) may correspond to a light-shielding pattern having light-shielding properties.

[0108] The pixel defining layer (PDL) can cover a portion of the anode (AE). For example, an opening (PDL-OP) exposing a portion of the anode (AE) can be defined in the pixel defining layer (PDL). An emission area (LA1) can be defined to correspond to the opening (PDL-OP). FIG. 5 illustrates one emission area (LA1) corresponding to the first color emission area (LA1) of FIG. 4A. Cross-sections corresponding to the second color emission area (LA2) and the third color emission area (LA3) of FIG. 4A may also be substantially the same as in FIG. 5. However, an emission layer (EL) of a different material from the first color emission area (LA1) may be arranged in the second color emission area (LA2) and the third color emission area (LA3). In addition, referring to the light-emitting area pair (UP) of FIG. 4A, a pixel defining layer (PDL) is disposed between the third color light-emitting area (LA3) of the first sub-region (UA1) and the third color light-emitting area (LA3) of the second sub-region (UA2).

The line components of the first conductive layer (220) and the line components of the second conductive layer (240) are briefly illustrated in FIG. 5.

[0112] The first insulating layer (210) may be directly disposed on the display panel (100). The first insulating layer (210) may be an inorganic layer including at least one of silicon nitride, silicon oxynitride, and silicon oxide. Each of the first conductive layer (220) and the second conductive layer (240) may have a single-layer structure or a multi-layer structure laminated along the third direction (DR3). The first conductive layer (220) and the second conductive layer (240) may include line components defining a mesh-shaped electrode. The line components of the first conductive layer (220) and the line components of the second conductive layer (240) may or may not be connected through a contact hole penetrating the second insulating layer (230) depending on the position.

[0115] Fig. 6a is a plan view of an input sensor (200) according to one embodiment of the present invention. Fig. 6b is a cross-sectional view of the input sensor (200) corresponding to II-II' of Fig. 6a.

[0116] As illustrated in FIG. 6A, the input sensor (200) includes a detection area (200-DA) and a non-detection area (200-NDA) adjacent to the detection area (200-DA). The detection area (200-DA) and the non-detection area (200-NDA) correspond to the display area (100-DA) and the non-display area (100-NDA) illustrated in FIG. 5, respectively. The input sensor (200) may include detection electrodes (SE) and signal lines (SL) connected thereto. In the present embodiment, the detection electrodes (SE) may include first electrodes (E1-1 to E1-4, or first detection electrodes) and second electrodes (E2-1 to E2-7, or second detection electrodes), and the signal lines (SL) may include first signal lines (SL1, or first sensor signal lines) and second signal lines (SL2, or second sensor signal lines).

[0117] In a detection area (200-DA), first electrodes (E1-1 to E1-4) and second electrodes (E2-1 to E2-7) that are insulated from each other and intersect each other are arranged. In a non-detection area (200-NDA), first signal lines (SL1) connected to the first electrodes (E1-1 to E1-4) and second signal lines (SL2) electrically connected to the second electrodes (E2-1 to E2-7) are arranged. Among the first signal lines (SL1) and the second signal lines (SL2), one of the signal lines (SL1 or SL2) transmits a driving signal for detecting an external input from an external circuit to the corresponding electrodes, and the other signal line (SL2 or SL1) outputs a sensing signal. Based on the sensing signal, a change in electrostatic capacity between the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) is measured. Although the present embodiment illustrates an input sensor of a mutual capping type, it is not limited thereto. The input sensor (200) may also have a self-capping type structure including one type of sensing electrode. The above-described electrode structure may be driven in a self-capping manner.

[0118] In this embodiment, four first electrodes (E1-1 to E1-4) and seven second electrodes (E2-1 to E2-7) are illustrated as examples. In addition, four first electrodes (E1-1 to E1-4) constituting different channels and seven second electrodes (E2-1 to E2-7) constituting different channels are illustrated as examples. In this case, 28 sensing units (SU) can be defined. For each sensing unit (SU), an intersection area of ​​a corresponding first electrode and a corresponding second electrode is arranged.

[0119] Meanwhile, according to one embodiment of the present invention, the first electrodes may define a plurality of first channel groups, and one first channel group may include two or more first electrodes. Two or more first electrodes belonging to the same first channel group may receive the same signal from each other or may be electrically connected to each other. Two or more first electrodes belonging to the same first channel group may be connected to the same signal line. The second electrodes may define a plurality of second channel groups, and one second channel group may include two or more second electrodes, which may receive the same signal from each other or may be electrically connected to each other. Two or more second electrodes belonging to the same second channel group may be connected to the same signal line.

[0120] According to the present embodiment, intersections of a corresponding first channel group and a corresponding second channel group may be arranged for each sensing unit (SU). For example, assuming that 12 first electrodes define 4 first channel groups and 21 second electrodes define 7 second channel groups, 28 sensing units (SU) may be formed. The first channel group may include 3 first electrodes arranged in series, and the second channel group may include 3 second electrodes arranged in series. In this case, 9 intersections of the first electrodes and the second electrodes are arranged for each of the sensing units (SU).

[0121] Again, referring to FIG. 6A, each of the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) may have a mesh shape in which a plurality of aperture areas are defined. Each of the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) includes a line component defining a plurality of aperture areas. Each of the plurality of aperture areas may, for example, overlap a corresponding emission area among the plurality of emission areas (LA1, LA2, LA3) of FIG. 4A.

[0122] Any one of the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) may have an integral shape. In the present embodiment, the second electrodes (E2-1 to E2-7) having an integral shape are exemplified. The second electrodes (E2-1 to E2-7) may include sensing portions (SP2) and intermediate portions (CP2). The sensing portions (SP2) may have a larger area than the intermediate portions (CP2) and may have an approximate rhombus shape. Each of the intermediate portions (CP2) is disposed between two adjacent sensing portions (SP2) among the sensing portions (SP2). The length of the intermediate portions (CP2) may be relatively short, and the intermediate portions (CP2) may be omitted. In this case, the sensing portion (SP2) may extend directly from the adjacent sensing portion (SP2).

[0123] Each of the first electrodes (E1-1 to E1-4) may include sensing patterns (SP1) and bridge patterns (CP1, or connection patterns). Two adjacent sensing patterns (SP1) may be connected by two bridge patterns (CP1), but the number of bridge patterns is not limited.

[0124] Referring to FIGS. 6A and 6B, the bridge patterns (CP1) may be formed from a first conductive layer (220), and the plurality of first electrodes (E1-1 to E1-4) and the sensing patterns (SP1) may be formed from a second conductive layer (240). The bridge pattern (CP1) may be connected to the sensing patterns (SP1) through a contact hole (TH-I) formed in the second insulating layer (230). However, the present invention is not limited thereto, and in one embodiment of the present invention, the bridge patterns (CP1) may be formed from a second conductive layer (240), and the plurality of second electrodes (E2-1 to E2-7) and the sensing patterns (SP1) may be formed from the first conductive layer (220).

[0125] Each of the first conductive layer (220) and the second conductive layer (240) includes a first metal layer (L1) and a second metal layer (L2) disposed on the first metal layer (L1). The first metal layer (L1) may have higher electrical conductivity and higher reflectivity than the second metal layer (L2). Therefore, the first metal layer (L1) corresponds to a practical signal transmission path, and the second metal layer (L2) reduces the reflectivity of the first conductive layer (220) and the second conductive layer (240). Each of the first conductive layer (220) and the second conductive layer (240) may include a third metal layer (L3) disposed under the first metal layer (L1), but this may be omitted. The third metal layer (L3) may be disposed to increase the adhesion of the first conductive layer (220) and the second conductive layer (240) to the first insulating layer (210). Each of the first conductive layer (220) and the second conductive layer (240) may have a three-layer structure of titanium / aluminum / titanium.

[0126] In the present embodiment, each of the first signal lines (SL1) and the second signal lines (SL2) of FIG. 6A may be formed from the first conductive layer (220) of FIG. 6B. Therefore, each of the first signal lines (SL1) and the second signal lines (SL2) of FIG. 6A may be arranged on the same layer as the bridge pattern (CP1) of FIG. 6B. However, the present invention is not limited thereto, and each of the first signal lines (SL1) and the second signal lines (SL2) may also be formed from the second conductive layer (240). Each of the first signal lines (SL1) and the second signal lines (SL2) may include both a line formed from the first conductive layer (220) and a line formed from the second conductive layer (240).

[0127] Fig. 7a is an enlarged plan view of the second conductive layer (240) corresponding to a portion of Fig. 6a. Fig. 7b is an enlarged plan view of the first portion (A1) of Fig. 7a. Fig. 7c is an enlarged plan view of the single-line portions (CA) corresponding to the first unit portion (UA-1) of Fig. 7b. Figs. 7d and 7e are enlarged plan views of the second portion (A2) of Fig. 7a.

[0128] In FIGS. 7A to 7E, the second conductive layer (240) refers to the second conductive layer (240) of FIG. 5. In FIGS. 7A to 7E, the second electrodes (E2-3 and E2-4) and / or sensing patterns (SP1) formed from the second conductive layer (240) are enlarged and illustrated.

[0129] Referring to FIGS. 7A to 7E, the line component of the sensing electrode (SE) includes a first line component (LE1) extending in the second direction (DR2) and a second line component (LE2) extending in the first direction (DR1). The first line component (LE1) and the second line component (LE2) are arranged between a plurality of first to third color light-emitting areas (LA1 to LA3). That is, the first line component (LE1) and the second line component (LE2) can be arranged entirely in the non-light-emitting area (NLA).

[0130] A first line component (LE1) and a second line component (LE2) can define a first aperture area (EOP1) corresponding to (or overlapping with) a first color light-emitting area (LA1), a second aperture area (EOP2) corresponding to a second color light-emitting area (LA2), and a third aperture area (EOP3) corresponding to a third color light-emitting area (LA3). In practice, the third aperture area (EOP3) corresponds to the light-emitting area pair (UP) described above. A plurality of first line components (LE1) and second line components (LE2) are arranged across the entire surface of the non-light-emitting area (NLA) and are connected to each other to define the first aperture area (EOP1), the second aperture area (EOP2), and the third aperture area (EOP3).

[0131] In addition, the single-line areas (CA) can be defined according to a predetermined rule in the first line component (LE1) and the second line component (LE2). The reason why the single-line areas (CA) are arranged according to a predetermined rule in the first line component (LE1) and the second line component (LE2), as described later, is to prevent the boundary area between the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) illustrated in FIG. 6A from being recognized as distinct from other areas. That is, the visibility of the boundary area is reduced. In fact, the ends of the first line component (LE1) and the first line component (LE1) are arranged so that they face each other in the boundary area, and the ends of the second line component (LE2) and the ends of the second line component (LE2) are arranged so that they face each other, so that a lot of external light reflection can occur in the cross sections of the corresponding line components. Points with high external light reflection are relatively more easily recognized, which causes a problem in that the visibility of the above-described boundary area is increased. The ends of the first line component (LE1) and the first line component (LE1) facing each other and the ends of the second line component (LE2) and the second line component (LE2) can be formed in an etching process that forms a first opening area (EOP1), a second opening area (EOP2), and a third opening area (EOP3). In the etching process, short-circuit areas (CA) are also formed.

[0132] In other words, the first line component (LE1) and the second line component (LE2) define a first aperture area (EOP1), a second aperture area (EOP2), and a third aperture area (EOP3), which correspond to a first color light-emitting area (LA1), a second color light-emitting area (LA2), and a third color light-emitting area (LA3), respectively. The aperture area (EOP3) corresponds to a light-emitting area pair (UP). A plurality of first and second line components (LE1, LE2) are arranged and connected in a non-light-emitting area (NLA) to form the aperture areas. Short-circuit areas (CA) are defined in the first and second line components (LE1, LE2) according to a set or predetermined rule to reduce the visibility of the boundary areas between the first and second electrodes (E1-1 to E1-4, E2-1 to E2-7). The boundary areas where the ends of the line components face each other can reflect a large amount of external light and thus have high visibility, and the single line areas (CA) increase the light reflectance of the inner areas of the first and second electrodes (E1-1 to E1-4, E2-1 to E2-7) in accordance with the light reflectance of the boundary areas.

[0133] Unlike in Fig. 6a, where the short-circuit areas (CA) are not shown and the boundary area between the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) is visibly visible (which means high visibility), in Fig. 7a, the short-circuit areas (CA) are shown and the visibility of the boundary area between the first electrode (E1-2) and the second electrodes (E2-3 and E2-4) can be reduced.

[0134] To reduce the visibility of the boundary region and to facilitate the signal flow of the sensing electrode, short-circuit areas (CA) can be defined according to the following rules. The following basic rules can be applied to each of the first electrodes (E1-1 to E1-4) and the second electrodes (E2-1 to E2-7) described with reference to Fig. 6a.

[0135] A single line area (CA) is defined in at least one of the two first line components (LE1) arranged on both sides of the first color light-emitting area (LA1) among the first line components (LE1) and the two second line components (LE2) arranged on both sides of the first color light-emitting area (LA1) among the second line components (LE2). In other words, a single line area (CA) is defined in at least one of the four line components surrounding the first color light-emitting area (LA1). At the same time, a single line area (CA) is not defined in one of the two first line components (LE1) arranged on both sides of the first color light-emitting area (LA1) among the first line components (LE1), and a single line area (CA) is not defined in one of the two second line components (LE2) arranged on both sides of the first color light-emitting area (LA1) among the second line components (LE2). A single line area (CA) is formed in one of the four line components surrounding the first color emitting area (LA1) to increase the reflectivity inside the sensing electrode (SE), and at the same time, the single line area (CA) is not formed in one of the first line components (LE1) and one of the second line components (LE2), thereby inducing signal flow in the first direction (DR1) and the second direction (DR2). In other words, the single line area (CA) is defined in at least one of the four line components surrounding the first color emitting area (LA1). Specifically, it may be in at least one of the two first line components (LE1) or the two second line components (LE2) located on the opposite sides of the first color emitting area (LA1). This arrangement helps to increase the reflectivity inside the sensing electrode (SE) and to ensure signal flow in both the first direction (DR1) and the second direction (DR2).

[0136] A single line area (CA) is defined around the second color emission area (LA2) according to the same rules as the first color emission area (LA1). A single line area (CA) is defined in at least one of the two first line components (LE1) arranged on both sides of the second color emission area (LA2) among the first line components (LE1) and the two second line components (LE2) arranged on both sides of the second color emission area (LA2) among the second line components (LE2). At the same time, a single line area (CA) is not defined in one of the two first line components (LE1) arranged on both sides of the second color emission area (LA2) among the first line components (LE1), and a single line area (CA) is not defined in one of the two second line components (LE2) arranged on both sides of the second color emission area (LA2) among the second line components (LE2). A single line area (CA) can be defined around the third color emission area (LA3) using the same rules as the first color emission area (LA1).

[0137] Referring to Fig. 7a, a plurality of unit areas (UA) described with reference to Fig. 4a are arranged within the sensing electrode (SE). Fig. 7a shows three unit areas (UA) as an example. Some of the unit areas (UA) among the plurality of unit areas (UA) may have single-line areas (CA) arranged therein that satisfy the basic rules described above.

[0138] Hereinafter, specific examples of single-line areas (CA) satisfying the above-described basic rules will be described with reference to FIGS. 7b and 7c. The rules of single-line areas (CA) will be described exemplarily, focusing on the first unit area (UA-1) shown in FIGS. 7b and 7c. Among the multiple unit areas (UA) shown in FIG. 7a, some of the unit areas (UA) may have the single-line areas (CA) arranged in the first unit area (UA-1) described below arranged in the same manner.

[0139] The single-line areas (CA) may include first to fourth single-line patterns (CTP1 to CTP4). A single-line pattern refers to two single-line areas formed around one light-emitting area, and in Fig. 7b, the single-line patterns are indicated with thick lines for easy representation.

[0140] For example, the first single-line pattern (CTP1) of FIG. 7b includes a first single-line area (PO1) formed in a second line component (LE2) disposed below a second color light-emitting area (LA2), as illustrated in FIG. 7c, and a second single-line area (PO2) formed in a first line component (LE1) disposed on the right side of the second color light-emitting area (LA2). According to the present embodiment, the first to fourth single-line patterns (CTP1 to CTP4) are positioned to correspond to the first to fourth sub-areas (UA1 to UA4), respectively. That is, the first single-line area (PO1) and the second single-line area (PO2) are disposed on orthogonal sides of the second color light-emitting area (LA2) of the first sub-area (UA1).

[0141] The first single-line pattern (CTP1) corresponds to the second color light-emitting area (LA2) of the first sub-area (UA1). The meaning of "the single-line pattern corresponds to the light-emitting area" is as described below. For example, both the first single-line area (PO1) and the second single-line area (PO2) are located between the second color light-emitting area (LA2) and other light-emitting areas around the second color light-emitting area (LA2). The two single-line areas of one single-line pattern are associated with three light-emitting areas, and the single-line pattern is defined as corresponding to the light-emitting area to which the two single-line areas are associated.

[0142] The second single line pattern (CTP2) corresponds to the second color light-emitting area (LA2) of the second sub-area (UA2). As illustrated in FIG. 7c, the second single line pattern (CTP2) includes a third single line area (PO3) defined in a second line component (LE2) arranged on one side of the second color light-emitting area (LA2) further away from the first color light-emitting area (LA1) of the second sub-area (UA2), and a fourth single line area (PO4) defined in a first line component (LE1) arranged on one side of the second color light-emitting area (LA2) further away from the third color light-emitting area (LA3) of the second sub-area (UA2).

[0143] The third single line pattern (CTP3) corresponds to the second color light-emitting area (LA2) of the third sub-area (UA3). As illustrated in FIG. 7c, it may include a fifth single line area (PO5) defined in the second line component (LE2) between the first color light-emitting area (LA1) of the third sub-area (UA3) and the second color light-emitting area (LA2) of the third sub-area (UA3), and a sixth single line area (PO6) defined in the first line component (LE1) between the second color light-emitting area (LA2) of the third sub-area (UA3) and the third color light-emitting area (LA3) of the third sub-area (UA3).

[0144] The fourth single line pattern (CTP4) corresponds to the second color light-emitting area (LA2) of the fourth sub-area (UA4). As illustrated in FIG. 7c, the fourth single line pattern (CTP4) includes a seventh single line area (PO7) defined in the second line component (LE2) between the first color light-emitting area (LA1) of the fourth sub-area (UA4) and the second color light-emitting area (LA2) of the fourth sub-area (UA4), and an eighth single line area (PO8) defined in the first line component (LE1) between the second color light-emitting area (LA2) of the fourth sub-area (UA4) and the third color light-emitting area (LA3) of the second sub-area (UA2).

[0145] Referring to FIGS. 7b and 7c, the third aperture area (EOP3) in which the third color light-emitting area (LA3) of the third sub-area (UA3) is arranged and the third aperture area (EOP3) in which the third color light-emitting area (LA3) of the fourth sub-area (UA4) is arranged are different aperture areas. In addition, the second line component (LE2) arranged between the third color light-emitting area (LA3) of the third sub-area (UA3) and the third color light-emitting area (LA3) of the fourth sub-area (UA4) may have a larger line width than the second line component (LE2) arranged at a different location.

[0146] The second line component (LE2) arranged between the third color light-emitting area (LA3) of the third sub-region (UA3) and the third color light-emitting area (LA3) of the fourth sub-region (UA4) may have a larger line width than the second line component (LE2) arranged between the first color light-emitting area (LA1) and the second color light-emitting area (LA2) of each of the first to fourth sub-regions (UA1 to UA4). In addition, the second line component (LE2) arranged between the third color light-emitting area (LA3) of the third sub-region (UA3) and the third color light-emitting area (LA3) of the fourth sub-region (UA4) may have a larger line width than the second line component (LE2) arranged between the second color light-emitting area (LA2) and the first color light-emitting area (LA1) of two adjacent unit regions in the second direction (DR2) among the first to fourth sub-regions (UA1 to UA4).

[0147] The second line components (LE2) arranged at other positions, excluding the second line component (LE2) arranged between the third color light-emitting area (LA3) of the third sub-region (UA3) and the third color light-emitting area (LA3) of the fourth sub-region (UA4) within the first unit region (UA-1), may have the same line width. For example, the second line component (LE2) arranged between the second color light-emitting area (LA2) of the third sub-region (UA3) and the first color light-emitting area (LA1) of the fourth sub-region (UA4) may have the same line width as the second line component (LE2) arranged between the first color light-emitting area (LA1) and the second color light-emitting area (LA2) of each of the third sub-regions (UA3). It may have the same line width as the second line component (LE2) arranged between the first color light-emitting area (LA1) and the second color light-emitting area (LA2) of each of the first to fourth sub-regions (UA1 to UA4).

[0148] Figure 7d is an enlarged view of the boundary area between the first electrode (E1-2) and the second electrode (E2-3).

[0149] In the boundary region between the first electrode (E1-2) and the second electrode (E2-3), the terminal of the first line component (LE1) of the first electrode (E1-2) and the terminal of the first line component (LE1) of the second electrode (E2-3) are spaced apart from each other and arranged to face each other. In addition, the terminal of the second line component (LE2) of the first electrode (E1-2) and the terminal of the second line component (LE2) of the second electrode (E2-3) are spaced apart from each other and arranged to face each other.

[0150] A boundary single-line area (BCA) is formed in the first line component (LE1) of the integral shape, and a boundary single-line area (BCA) is formed in the second line component (LE2) of the integral shape, thereby forming a boundary area between the first electrode (E1-2) and the second electrode (E2-3). In Fig. 7d, the boundary single-line area (BCA) is indicated by a thick line for easy representation.

[0151] The boundary broken line area (BCA) may include first boundary broken line patterns (BTP1) and second boundary broken line patterns (BTP2). The first boundary broken line pattern (BTP1) includes a first boundary broken line area (BPO1) and a second boundary broken line area (BPO2) formed on each of two first line components (LE1) arranged on both sides of one light-emitting area. In the present embodiment, the first boundary broken line pattern (BTP1) may be arranged to correspond to the third color light-emitting area (LA3). In addition, the first boundary broken line pattern (BTP1) is formed on the first line component (LE1) arranged between the third color light-emitting area (LA3) and the second color light-emitting area (LA2). The first boundary line pattern (BTP1) electrically disconnects the first electrode (E1-2) and the second electrode (E2-3) in the second direction (DR2) by cutting the first line components (LE1).

[0152] The second boundary line pattern (BTP2) includes a third boundary line area (BPO3) and a fourth boundary line area (BPO4) formed in each of two second line components (LE2) arranged on both sides centered on one light-emitting area. In the present embodiment, the second boundary line pattern (BTP2) may be arranged to correspond to the first color light-emitting area (LA1). Since the second boundary line pattern (BTP) cuts the second line components (LE2), it electrically disconnects the first electrode (E1-2) and the second electrode (E2-3) in the first direction (DR1).

[0153] The two second line components (LE2) arranged at the boundary area between the first electrode (E1-2) and the second electrode (E2-3) and arranged on both sides of the first color light-emitting area (LA1) have a shorter length than the second line component (LE2) arranged at each of the first electrode (E1-2) and the second electrode (E2-3) and arranged on one side of the first color light-emitting area (LA1) that is not disconnected. The two second line components (LE2) arranged at the boundary area described above have substantially the same length as the disconnected second line component (LE2) arranged at each of the first electrode (E1-2) and the second electrode (E2-3) and arranged on one side of the first color light-emitting area (LA1). The length is measured as a numerical value of the disconnected first line component (LE1) extended in the first direction (DR1) from the second line component (LE2).

[0154] A boundary short-circuit area (BCA) may include a plurality of first boundary short-circuit patterns (BTP1) and a plurality of second boundary short-circuit patterns (BTP2). The plurality of first boundary short-circuit patterns (BTP1) and the plurality of second boundary short-circuit patterns (BTP2) may be arranged alternately.

[0155] Fig. 7d illustrates the first unit area (UA-1) described with reference to Figs. 7b and 7c. Some of the first to fourth single-line patterns (CTP1 to CTP4) arranged in the first unit area (UA-1) may constitute a boundary single-line area (BCA). At least one of the first to eighth single-line areas (PO1 to PO8, see Fig. 7c) of the unit area (UA) may be the first to fourth boundary single-line areas (BPO1 to BPO4) of the boundary single-line area (BCA).

[0156] FIG. 7d illustrates an example in which the fifth single-line area (PO5) of the third single-line pattern (CTP3) corresponds to the fourth boundary single-line areas (BPO4), and the sixth single-line area (PO6) of the third single-line pattern (CTP3) corresponds to the first boundary single-line areas (BPO1).

[0157] Fig. 7e is an enlarged view of the boundary area of ​​the first electrode (E1-2) and the second electrode (E2-3) that are the same as those in Fig. 7d. Fig. 7e additionally shows a second unit area (UA-2) adjacent to the first unit area (UA-1). In the second unit area (UA-2), the basic rule explained with reference to Fig. 7a is satisfied, but single-line areas (CA-1) different from the single-line areas (CA) of the first unit area (UA-1) shown in Figs. 7b and 7d are arranged.

[0158] The single-line areas (CA-1) of the second unit area (UA-2) may include a first single-line pattern (CTP10), a second single-line pattern (CTP20), a third single-line pattern (CTP3), and a fourth single-line pattern (CTP40). The single-line areas (CA) of the first unit area (UA-1) and the first single-line pattern (CTP10), the second single-line pattern (CTP20), and the fourth single-line pattern (CTP40) may be different.

[0159] The first single line pattern (CTP10), as illustrated in FIG. 7e, includes a first single line area (PO1) formed in a second line component (LE2) disposed below a second color light-emitting area (LA2) and a second single line area (PO20) formed in a first line component (LE1) disposed on the left side of the second color light-emitting area (LA2). The second single line pattern (CTP2) corresponds to the second color light-emitting area (LA2) of the second sub-area (UA2). The second single line pattern (CTP20) includes a third single line area (PO30) defined in a second line component (LE2) disposed between the first color light-emitting area (LA1) and the second color light-emitting area (LA2) and a fourth single line area (PO40) defined in the first line component (LE1) disposed on the right side of the third color light-emitting area (LA3). That is, the third single line area (PO30) is disposed on one side of the second second color light emitting area of ​​the second sub-area that is further away from the first color light emitting area of ​​the second sub-area corresponding to the first unit area than the other side of the second color light emitting area of ​​the second sub-area. In addition, the fourth single line area (PO40) is disposed on one side of the second color light emitting area of ​​the sub-area that is further away from the other side of the second color light emitting area of ​​the second sub-area corresponding to the unit area than the other side of the second color light emitting area of ​​the second sub-area. The fourth single line pattern (CTP40) includes a seventh single line area (PO70) defined in a second line component (LE2) disposed below the second color light emitting area (LA2) and an eighth single line area (PO8) defined in a first line component (LE1) disposed on the left side of the second color light emitting area (LA2).

[0160] At least a portion of the first single-line pattern (CTP10), the second single-line pattern (CTP20), and the fourth single-line pattern (CTP40) may be different from the first single-line pattern (CTP1), the second single-line pattern (CTP2), and the fourth single-line pattern (CTP4) of the first unit area (UA-1) illustrated in FIGS. 7b to 7d to form a boundary single-line area (BCA).

[0161] FIGS. 8A and 8B are enlarged plan views of a portion of an input sensor according to one embodiment of the present invention.

[0162] Figures 8a and 8b are enlarged views of the intersection area of ​​the first electrode (E1-2) and the second electrode (E2-3) illustrated in Figure 7a. The bridge pattern (CP1) described with reference to Figure 6a is arranged in the intersection area of ​​the first electrode (E1-2) and the second electrode (E2-3), but since Figures 8a and 8b only illustrate the second conductive layer (240) of Figure 5, the bridge pattern (CP1) is not illustrated.

[0163] Referring to Fig. 8a, a boundary area is formed between the sensing patterns (SP1) of the first electrode (E1-2) and the sensing portions (SP2) and the middle portion (CP2) of the second electrode (E2-3) at the intersection of the first electrode (E1-2) and the second electrode (E2-3). The boundary single-line area (BCA) is indicated by a bold line. The boundary single-line area (BCA) may include a first boundary single-line pattern (BTP1) and a second boundary single-line pattern (BTP2). In a part of the boundary single-line area (BCA), the first boundary single-line patterns (BTP1) and the second boundary single-line patterns (BTP2) may be alternately arranged, and the boundary single-line area (BCA) may further include third boundary single-line patterns (BTP3).

[0164] The third boundary single line patterns (BTP3) include single line areas formed in all line components arranged between four or more consecutively arranged light-emitting areas. In the present embodiment, the third boundary single line patterns (BTP3) include four single line areas formed in each of four first line components (LE1) arranged between five light-emitting areas in the first direction (DR1). In the present embodiment, the third boundary single line patterns (BTP3) may be substantially the same as two first boundary single line patterns (BTP1) arranged consecutively.

[0165] Fig. 8a illustrates a third unit area (UA-3) and a fourth unit area (UA-4) as examples. The third unit area (UA-3) and the fourth unit area (UA-4) satisfy the basic rule described with reference to Fig. 7a, but the single-line areas (CA) of the first unit area (UA-1) illustrated in Figs. 7b and 7d are arranged in different manners. This is because, like the second unit area (UA-2), at least some of the single-line areas of the third unit area (UA-3) and the fourth unit area (UA-4) form a boundary single-line area (BCA).

[0166] Referring to Fig. 8b, a boundary single line area (BCA) of a different shape from that of Fig. 8a is illustrated. The shape of the middle portion (CP2) can be determined by the shape of the boundary single line area (BCA). The boundary single line area (BCA) includes first boundary single line patterns (BTP1) and second boundary single line patterns (BTP2).

[0167] In addition, the boundary single line area (BCA) may further include first-first boundary single line patterns (BTP1-1). In addition, the first-first boundary single line patterns (BTP1-1) are formed on each of the two first line components (LE1) arranged on both sides of the third color light-emitting area (LA3), but, unlike the first boundary single line pattern (BTP1), they are formed on the first line component (LE1) arranged between the third color light-emitting area (LA3) and the first color light-emitting area (LA1).

[0168] The third boundary single line patterns (BTP3) according to the present embodiment include five single line areas each formed in five second line components (LE2) arranged between six light-emitting areas arranged consecutively in the second direction (DR2).

[0169] Additionally, the boundary single line area (BCA) may further include a fourth boundary single line pattern (BTP4). The fourth boundary single line pattern (BTP4) may be formed in one line component positioned between two adjacent light-emitting areas. In the present embodiment, the fourth boundary single line pattern (BTP4) may be formed in the second line component (LE2) positioned between the first color light-emitting area (LA1) and the second color light-emitting area (LA2).

[0170] According to the present invention, since the short-circuit regions are arranged in a predetermined order within the sensing electrodes, the phenomenon of the boundary region between the sensing electrodes being clearly visible can be reduced. This is because the amount of external light reflected by the boundary region and the sensing electrode is similar.

[0171] Based on each of the light-emitting regions, a line component extending in the first direction and a line component extending in the second direction are respectively arranged. Therefore, the current flow in the first or second direction of the detection electrode can be smooth.
