[0104] The non-overlapping area NOA can be an area in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 do not overlap each other, and can include an area in which the first conductive pattern layer CP1 is disposed and an area in which the second conductive pattern layer CP2 is disposed. For example, the non-overlapping area NOA can include an area in which the first conductive pattern layer CP1 is disposed without the second conductive pattern layer CP2 and an area in which the second conductive pattern layer CP2 is disposed without the first conductive pattern layer CP1. In a plan view, the non-overlapping area NOA can not overlap the sub-pixel area SPXA (see Figure 3 ).
[0105] The cut area CA can be an area formed by cutting either one of the first conductive pattern layer CP1 and the second conductive pattern layer CP2. For example, the cut area CA can be an area formed by cutting at least a portion of the second conductive pattern layer CP2 to electrically separate the first sensing electrode SP1 and the second sensing electrode SP2 from each other. For example, the first sensing electrode SP1 and the second sensing electrode SP2 can be adjacent to each other with the cut area CA interposed therebetween, and can be physically spaced apart from each other. In a plan view, the cut area CA can not overlap the sub-pixel area SPXA.
[0106] In a plan view, the overlapping area OA can be an area in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 overlap each other. In an embodiment, the first conductive pattern layer CP1 and the second conductive pattern layer CP2 can be disposed not to overlap the sub-pixel area SPXA in a plan view. The first conductive pattern layer CP1 and the second conductive pattern layer CP2 can partially overlap each other, thereby defining the overlapping area OA. In a plan view, the overlapping area OA can not overlap the sub-pixel area SPXA.
[0107] Accordingly, the sensor layer TSP can include areas explicitly defined based on the structure of the first conductive pattern layer CP1 and the second conductive pattern layer CP2. Experimentally, the amount of reflection of external light applied from the outside of the display device DD can vary in the non-overlapping area NOA, the cut area CA, and the overlapping area OA. In this case, there can be a risk of a reduction in visibility due to external light.
[0108] However, according to an embodiment, the identification pattern portions NIP and OIP (see Figure 10 ) can compensate for the difference in the structure of the first conductive pattern layer CP1 and the second conductive pattern layer CP2 between the non-overlapping area NOA, the cut area CA, and the overlapping area OA of the sensor layer TSP. Accordingly, it is possible to reduce the risk of deterioration in visibility due to reflection of external light, thereby providing a display device DD having improved display quality. Reference will be made to Figure 10Details of identifying the patterned portion NIP and the OIP are described with subsequent figures.
[0109] The sensing electrode SP can include cells C and bridges BRD. The cells C can have a relatively large surface area. The bridges BRD can have a relatively small surface area. The cells C adjacent to each other can be electrically connected to each other by the bridges BRD. The cells C can include first cells C1 and second cells C2. The bridges BRD can include first bridges BRD1 and second bridges BRD2.
[0110] In an embodiment, the first cells C1 and the second cells C2 can be formed by the second conductive pattern layer CP2. The first bridges BRD1 can be formed by the second conductive pattern layer CP2. A portion of the second bridges BRD2 can be formed by the first conductive pattern layer CP1. Another portion of the second bridges BRD2 can be formed by the second conductive pattern layer CP2. However, the disclosure is not necessarily limited to the above example. For example, the first cells C1 and the second cells C2 can be formed by the first conductive pattern layer CP1. The first bridges BRD1 can be formed by the first conductive pattern layer CP1. A portion of the second bridges BRD2 can be formed by the second conductive pattern layer CP2. Another portion of the second bridges BRD2 can be formed by the first conductive pattern layer CP1.
[0111] In an embodiment, the sensing electrode SP can form a mesh structure. The cells C and the bridges BRD can form the mesh structure. For example, the second conductive pattern layer CP2 for forming the sensing electrode SP can be patterned according to the mesh structure.
[0112] The first sensing electrode SP1 can have a structure in which the first cells C1 each having a relatively large surface area and the first bridges BRD1 having a relatively small surface area are connected to each other. For example, the first cells C1 can include a 1-1 cell C1-1 and a 1-2 cell C1-2. The first bridges BRD1 can electrically connect the 1-1 cell C1-1 and the 1-2 cell C1-2 to each other.
[0113] The second sensing electrode SP2 can have a structure in which the second cells C2 each having a relatively large surface area and the second bridges BRD2 having a relatively small surface area are connected to each other. For example, the second cells C2 can include a 2-1 cell C2-1 and a 2-2 cell C2-2. The second bridges BRD2 can electrically connect the 2-1 cell C2-1 and the 2-2 cell C2-2 to each other.
[0114] In an embodiment, the second bridge BRD2 can be electrically connected to the 2-1st unit C2-1 through a contactor CNT, and can be electrically connected to the 2-2nd unit C2-2 through another contactor CNT. Accordingly, the second bridge BRD2, whose layers are disposed on different layers from the second unit C2, can electrically connect the 2-1st unit C2-1 and the 2-2nd unit C2-2 to each other through the contactors CNT. In an embodiment, the contactors CNT can pass through the second insulating layer INS2.
[0115] The first unit C1 and the second unit C2 can each have a rhombus shape overall (refer to Figure 6 ). However, the shape of each of the first unit C1 and the second unit C2 is not necessarily specifically limited to the above-described shape. For example, each of the first unit C1 and the second unit C2 can have a rectangular shape overall (refer to Figure 7 ).
[0116] According to an embodiment, a cut region CA can be defined between the sensing electrodes SP that are electrically spaced apart from each other. For example, the first sensing electrode SP1 and the second sensing electrode SP2 can be adjacent to each other, with the cut region CA interposed therebetween. The cut region CA can be defined in a region between the first sensing electrode SP1 and the second sensing electrode SP2. For example, the cut region CA can be disposed (or formed or defined) between the 1-1st unit C1-1 and the 1-2nd unit C1-2 and the 2-1st unit C2-1 and the 2-2nd unit C2-2. The cut region CA can be disposed (or formed or defined) between the first bridge BRD1 and the 2-1st unit C2-1 and the 2-2nd unit C2-2.
[0117] Hereinafter, a cross-sectional structure of a display device DD according to an embodiment will be described with reference to Figure 9 .
[0118] Figure 9 is a schematic cross-sectional view illustrating a display device DD according to an embodiment.
[0119] With reference to Figure 9 , the emission structure EL can include a first emission structure EL1 included in the first sub-pixel SPX1, a second emission structure EL2 included in the second sub-pixel SPX2, and a third emission structure EL3 included in the third sub-pixel SPX3. The first emission structure EL1 can emit light of a first color (e.g., red), and can form a first sub-pixel region SPXA1. The second emission structure EL2 can emit light of a second color (e.g., green), and can form a second sub-pixel region SPXA2. The third emission structure EL3 can emit light of a third color (e.g., blue), and can form a third sub-pixel region SPXA3.
[0120] In the sensor layer TSP, the first conductive pattern layer CP1 and the second conductive pattern layer CP2 can be disposed on different layers, thereby forming a structure of the sensing electrode SP.
[0121] An upper layer UL can be disposed on the sensor layer TSP. The upper layer UL can transmit at least a portion of light provided from the emission structure EL. In an embodiment, the upper layer UL can include a light blocking layer LBL, color filters CF1 to CF3, and an overcoat layer OC. However, the structure of the upper layer UL is not necessarily limited to the above-described example.
[0122] In a plan view, the light blocking layer LBL can overlap the first conductive pattern layer CP1 and the second conductive pattern layer CP2. The light blocking layer LBL can include a light blocking material such as a material that can reflect or absorb light. Alternatively, in an embodiment, the light blocking layer LBL can be formed by overlapping the first to third color filters CF1 to CF3.
[0123] The color filters CF1 to CF3 can include a first color filter CF1 disposed in the first sub-pixel area SPXA1, a second color filter CF2 disposed in the second sub-pixel area SPXA2, and a third color filter CF3 disposed in the third sub-pixel area SPXA3.
[0124] The first color filter CF1 can be disposed in the first sub-pixel area SPXA1. The first color filter CF1 can include a color filter material (e.g., a pigment or a dye) for selectively allowing light of a first color (e.g., red) to pass therethrough.
[0125] The second color filter CF2 can be disposed in the second sub-pixel area SPXA2. The second color filter CF2 can include a color filter material (e.g., a pigment or a dye) for selectively allowing light of a second color (e.g., green) to pass therethrough.
[0126] The third color filter CF3 can be disposed in the third sub-pixel area SPXA3. The third color filter CF3 can include a color filter material (e.g., a pigment or a dye) for selectively allowing light of a third color (e.g., blue) to pass therethrough.
[0127] The overcoat layer OC can be disposed on the color filters CF1 to CF3. The overcoat layer OC can include various materials suitable for protecting the layers disposed thereunder from foreign substances. For example, the overcoat layer OC can include an inorganic insulating layer and / or an organic insulating layer. For example, the overcoat layer OC can include an epoxy resin, but embodiments are not necessarily limited thereto.
[0128] In an embodiment, the size (or surface area) of the sub-pixel regions SPXA can be different from each other. The surface area of the first sub-pixel region SPXA1, the second sub-pixel region SPXA2, and the third sub-pixel region SPXA3 can be different from each other. For example, the surface area of the third sub-pixel region SPXA3 can be larger than the surface area of the second sub-pixel region SPXA2. The surface area of the second sub-pixel region SPXA2 can be larger than the surface area of the first sub-pixel region SPXA1. In an embodiment, the surface area of some sub-pixel regions SPXA can be different from the surface area of other sub-pixel regions SPXA, so that the emission efficiency deviation between the sub-pixels SPX due to color can be compensated for.
[0129] The cross-sectional structure of the display device DD is not necessarily limited to the above-described example. For example, according to an embodiment, the display device DD can further include a color conversion layer including quantum dots capable of converting the color of light applied thereto. The color conversion layer can be disposed on the light emitting element LD (see FIG. 1A). The position of the color conversion layer is not necessarily limited specifically to what is described herein. Figure 3

[0132] According to an embodiment, the sub-pixels SPX can be arranged in various structures. Hereinafter, an embodiment in which the sub-pixels SPX are arranged according to an S stripe structure will be described. In the following description, the positional relationship of the sub-pixels SPX1, SPX2, and SPX3 can correspond to the positional relationship of the sub-pixel regions SPXA1, SPXA2, and SPXA3 and / or the emission structures EL1, EL2, and EL3.
[0133] The first sub-pixel SPX1 and the second sub-pixel SPX2 can form a first pixel column COL1. The first sub-pixel SPX1 and the second sub-pixel SPX2 can be sequentially arranged in the first direction DR1. The first sub-pixel SPX1 and the second sub-pixel SPX2 can be alternately arranged in the first direction DR1. The first sub-pixel SPX1 and the second sub-pixel SPX2 can be arranged in the first pixel column COL1, and the third sub-pixel SPX3 is not arranged in the first pixel column COL1.
[0134] The third sub-pixel SPX3 can form a second pixel column COL2. The third sub-pixel SPX3 can be sequentially arranged in the first direction DR1. The third sub-pixel SPX3 can be arranged in the second pixel column COL2, and the first sub-pixel SPX1 and the second sub-pixel SPX2 are not arranged in the second pixel column COL2.
[0135] The first pixel column COL1 and the second pixel column COL2 can be adjacent to each other in the second direction DR2. For example, the first sub-pixel SPX1 can be adjacent to the third sub-pixel SPX3 in the second direction DR2. The second sub-pixel SPX2 can be adjacent to the third sub-pixel SPX3 in the second direction DR2.
[0136] The first pixel column COL1 and the second pixel column COL2 can be alternately arranged in the second direction DR2. For example, each second pixel column COL2 can be arranged between two first pixel columns COL1. Each first pixel column COL1 can be arranged between two second pixel columns COL2.
[0137] The first sub-pixel SPX1 and the second sub-pixel SPX2 adjacent to each other in the first direction DR1 and the third sub-pixel SPX3 adjacent to the first sub-pixel SPX1 and the second sub-pixel SPX2 in the second direction DR2 can form a pixel PXL (or a pixel unit).
[0138] In an embodiment, the first conductive pattern layer CP1 and the second conductive pattern layer CP2 can be arranged in a peripheral portion of the sub-pixel area SPXA. For example, the second conductive pattern layer CP2 can be arranged around the sub-pixel SPX (or the sub-pixel area SPXA). In a plan view, the second conductive pattern layer CP2 can surround at least a portion of the sub-pixel area SPXA.
[0139] As described above, identifying the pattern portions NIP and OIP can compensate for the difference in the structure of the first conductive pattern layer CP1 and the second conductive pattern layer CP2 between the non-overlapping area NOA, the cutting area CA, and the overlapping area OA of the sensor layer TSP.
[0140] According to an embodiment, the cutting area CA can include a plurality of cutting areas CA. According to an embodiment, the non-overlapping identification pattern portion NIP can include a plurality of non-overlapping identification pattern portions NIP. The plurality of non-overlapping identification pattern portions NIP can correspond to positions of the plurality of cutting areas CA.
[0141] For example, the plurality of non-overlapping identification pattern portions NIP can overlap the plurality of cutting areas CA in the first direction DR1. The plurality of non-overlapping identification pattern portions NIP can be disposed at respective positions offset from positions where the plurality of cutting areas CA are disposed in the first direction DR1 (see FIG. 10A, for example). For example, the plurality of cutting areas CA can be arranged in a matrix structure based on the first direction DR1 and the second direction DR2. The plurality of non-overlapping identification pattern portions NIP can be arranged based on positions to which the matrix structure is offset in the first direction DR1. Figure 12 For example, the plurality of non-overlapping identification pattern portions NIP can overlap the plurality of cutting areas CA in the first direction DR1. The plurality of non-overlapping identification pattern portions NIP can be disposed at respective positions offset from positions where the plurality of cutting areas CA are disposed in the first direction DR1 (see FIG. 10A, for example). For example, the plurality of cutting areas CA can be arranged in a matrix structure based on the first direction DR1 and the second direction DR2. The plurality of non-overlapping identification pattern portions NIP can be arranged based on positions to which the matrix structure is offset in the first direction DR1.
[0142] In an embodiment, the cutting area CA and the non-overlapping identification pattern portion NIP can be adjacent to each other in the first direction DR1, with any one of the sub-pixels SPXA interposed therebetween. Each of the cutting area CA and the non-overlapping identification pattern portion NIP can be disposed between the first sub-pixel area SPXA1 and the second sub-pixel area SPXA2 based on the first direction DR1. The cutting area CA and the non-overlapping identification pattern portion NIP can be adjacent to each other, with the first sub-pixel area SPXA1 or the second sub-pixel area SPXA2 interposed therebetween.
[0143] In this case, even when the cutting area CA separates the first sensing electrode SP1 and the second sensing electrode SP2 from each other, the non-overlapping identification pattern portion NIP can compensate for a difference in reflection of external light, thereby mitigating the risk of reduced visibility.
[0144] In an embodiment, the non-overlapping identification pattern portion NIP can include a bump structure. For example, the non-overlapping identification pattern portion NIP can include a portion protruding in a planar direction in some areas of the first conductive pattern layer CP1 and the second conductive pattern layer CP2. In this case, the non-overlapping identification pattern portion NIP can have a shape extending in two or more directions. As described above, even when the cutting area CA separates the first sensing electrode SP1 and the second sensing electrode SP2 from each other, the non-overlapping identification pattern portion NIP can change a reflection pattern of external light and compensate for a difference in reflection of external light. For example, in a plan view, the non-overlapping identification pattern portion NIP can have a circular shape or an elliptical shape. However, the present disclosure is not necessarily limited to the above-described examples.
[0145] In an embodiment, the non-overlapping identification pattern portion NIP can be formed of at least one of the first conductive pattern layer CP1 and the second conductive pattern layer CP2. For example, the non-overlapping identification pattern portion NIP can include a first non-overlapping identification pattern portion NIP1 formed of the first conductive pattern layer CP1 and a second non-overlapping identification pattern portion NIP2 formed of the second conductive pattern layer CP2.
[0146] In an embodiment, the overlapping area OA can include a point-type overlapping area OA_P and a line-type overlapping area OA_L.
[0147] In some areas of the sensing area SA (refer to FIG. 1A), the first conductive pattern layer CP1 and the second conductive pattern layer CP2 can extend in the same direction, and areas in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 overlap each other can extend in a linear shape. Accordingly, areas in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 extend in parallel to each other and overlap each other can be defined as the line-type overlapping area OA_L. Figure 1
[0148] In some areas of the sensing area SA, the first conductive pattern layer CP1 and the second conductive pattern layer CP2 can extend in different directions, and the first conductive pattern layer CP1 and the second conductive pattern layer CP2 can cross each other. Accordingly, areas in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 cross each other can be defined as the point-type overlapping area OA_P.
[0149] Referring to FIG. 1A, Figures 10 to 18 , the display device DD (refer to FIG. 1A) can include an overlapping identification pattern portion OIP formed in the overlapping area OA to improve the visibility of the display device DD. In an embodiment, the overlapping identification pattern portion OIP can not overlap the cutting area CA in the first direction DR1 or the second direction DR2. For example, the overlapping identification pattern portion OIP can not overlap the cutting area CA in the first direction DR1. Figure 1 In an embodiment, the reflection of external light in the overlapping area OA can be different from the reflection of external light in the non-overlapping area NOA and the cutting area CA. In an embodiment, the overlapping identification pattern portion OIP can be formed in the overlapping area OA to compensate for the difference in the reflection of external light between the areas.
[0150] Depending on the shape of the overlapping area OA, the overlapping identification pattern portion OIP can have different shapes. Hereinafter, an embodiment including the overlapping identification pattern portion OIP having a different structure for each area of the overlapping area OA will be described.
[0151]
[0152] Figures 10 to 13 An embodiment is illustrated in which the display device DD includes non-overlapping identification pattern portions NIP corresponding to the cutting area CA and further includes a point-type overlapping identification pattern portion OIP_P formed in a point-type overlapping area OA_P.
[0153] In an embodiment, the overlapping identification pattern portion OIP can include a point-type overlapping identification pattern portion OIP_P. The point-type overlapping identification pattern portion OIP_P can be referred to as a first overlapping identification pattern portion.
[0154] The point-type overlapping identification pattern portion OIP_P can be disposed in a point-type overlapping area OA_P. The point-type overlapping identification pattern portion OIP_P can be formed in an area in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 extending in different directions cross each other.
[0155] The point-type overlapping identification pattern portion OIP_P can not overlap with the sub-pixel area SPXA in the first direction DR1. The point-type overlapping identification pattern portion OIP_P can not overlap with the sub-pixel area SPXA in the second direction DR2.
[0156] The point-type overlapping identification pattern portion OIP_P can include a plurality of point-type overlapping identification pattern portions OIP_P. The number of the point-type overlapping identification pattern portions OIP_P formed around the sub-pixel area SPXA is not necessarily limited to what is described herein. In an embodiment, the plurality of point-type overlapping identification pattern portions OIP_P can be sequentially arranged in the second direction DR2.
[0157] The point-type overlapping identification pattern portion OIP_P can overlap with a non-overlapping identification pattern portion NIP (e.g., a first non-overlapping identification pattern portion NIP1) in the second direction DR2 (refer to Figure 12 and can not overlap with non-overlapping identification pattern portions NIP (e.g., the first non-overlapping identification pattern portion NIP1 and the second non-overlapping identification pattern portion NIP2) in the first direction DR1. In an embodiment, the point-type overlapping identification pattern portion OIP_P can not overlap with a portion (e.g., the second non-overlapping identification pattern portion NIP2) of the non-overlapping identification pattern portion NIP in the second direction DR2.
[0158] The point-type overlapping identification pattern portion OIP_P can have a relatively small surface area. For example, the point-type overlapping identification pattern portion OIP_P can have a smaller surface area than a surface area of the non-overlapping identification pattern portion NIP. For example, the point-type overlapping identification pattern portion OIP_P can include a protrusion PRU having a smaller surface area than a surface area of the non-overlapping identification pattern portion NIP. The protrusion PRU can be formed around the point-type overlapping area OA_P, and can be formed by either one of the first conductive pattern layer CP1 and the second conductive pattern layer CP2. For example, in an embodiment, the protrusion PRU can be formed by the second conductive pattern layer CP2.
[0159] In an embodiment, the point-type overlapping identification pattern portion OIP_P can have a structure protruding in two or more directions from the point-type overlapping area OA_P. For example, the protrusion PRU can include a plurality of protrusions PRU. The plurality of protrusions PRU can extend in two or more different directions from the point-type overlapping area OA_P. In an embodiment, the above-described different directions can be different from the first direction DR1 and the second direction DR2.
[0160] For example (with reference to FIG. 4A), Figure 10 The plurality of protrusions PRU can respectively extend in four directions, whereby the point-type overlapping identification pattern portion OIP_P can have an approximately "X" shape. For example, the plurality of protrusions PRU can include first to fourth protrusions. In the point-type overlapping area OA_P, the first protrusion can extend in an upper right direction, the second protrusion can extend in a lower right direction, the third protrusion can extend in a lower left direction, and the fourth protrusion can extend in an upper left direction.
[0161] For example (with reference to FIG. 4A), Figure 11 The plurality of protrusions PRU can respectively extend in two directions. Accordingly, the point-type overlapping identification pattern portion OIP_P can have at least an approximately diagonal bar shape such as a diagonal line shape (e.g., a " / " shape) and / or at least an approximately backslash shape such as a back diagonal line shape (e.g., a shape in which the left and right of the " / " are reversed). For example, the plurality of protrusions PRU can include first and second protrusions, and in the point-type overlapping area OA_P, the first protrusion can extend in an upper right direction and the second protrusion can extend in a lower left direction. Alternatively, the plurality of protrusions PRU can include first and second protrusions, and in the point-type overlapping area OA_P, the first protrusion can extend in an upper left direction and the second protrusion can extend in a lower right direction. In an embodiment, the point-type overlapping identification pattern portion OIP_P of the diagonal bar shape (e.g., a first point-type overlapping identification pattern portion) and the point-type overlapping identification pattern portion OIP_P of the backslash shape (e.g., a second point-type overlapping identification pattern portion) can be alternately arranged in a certain direction (e.g., the second direction DR2).
[0162] Experimentally, in a case where the first conductive pattern layer CP1 and the second conductive pattern layer CP2 overlap in the point-type overlapping area OA_P, reflected light from external light applied in the point-type overlapping area OA_P can have a relatively low light amount, and there can be a risk of perceiving the reflected light in the form of a point.
[0163] In an embodiment, the point-type overlapping identification pattern portion OIP_P can include a protrusion PRU extending in two or more directions. Accordingly, the protrusion PRU can disperse reflected light generated from the point-type overlapping area OA_P. For example, the protrusion PRU can disperse a reflection angle of the reflected light generated in the point-type overlapping area OA_P. In this case, the intensity of the reflected light having a relatively low light amount can be reduced, so that the risk of perceiving reflection of external light in the point-type overlapping area OA_P can be reduced.
[0164] Figures 14 to 17 An embodiment in which the display device DD includes a non-overlapping identification pattern portion NIP corresponding to the cut area CA and further includes a line-type overlapping identification pattern portion OIP_L formed in a line-type overlapping area OA_L is illustrated.
[0165] In an embodiment, the overlapping identification pattern portion OIP can include a line-type overlapping identification pattern portion OIP_L. The line-type overlapping identification pattern portion OIP_L can be referred to as a second overlapping identification pattern portion.
[0166] The line-type overlapping identification pattern portion OIP_L can be disposed in a line-type overlapping area OA_L. The line-type overlapping identification pattern portion OIP_L can be formed in an area in which the first conductive pattern layer CP1 and the second conductive pattern layer CP2 extending in the same direction overlap each other.
[0167] The line-type overlapping identification pattern portion OIP_L can not overlap the sub-pixel area SPXA in the first direction DR1. The line-type overlapping identification pattern portion OIP_L can overlap the sub-pixel area SPXA in the second direction DR2.
[0168] The line-type overlapping identification pattern portion OIP_L can include a plurality of line-type overlapping identification pattern portions OIP_L. The number of the line-type overlapping identification pattern portions OIP_L formed around the sub-pixel area SPXA is not necessarily specifically limited to what is described herein. In an embodiment, the plurality of line-type overlapping identification pattern portions OIP_L can be sequentially arranged in the first direction DR1. In an embodiment, the plurality of line-type overlapping identification pattern portions OIP_L can be spaced apart from each other at the same interval. However, the disclosure is not necessarily limited to the above-described example.
[0169] The line-type overlapping identification pattern portion OIP_L can be partially overlapped with the non-overlapping identification pattern portion NIP (e.g., the first non-overlapping identification pattern portion NIP1 and the second non-overlapping identification pattern portion NIP2) or the cut region CA in the second direction DR2. However, the disclosure is not necessarily limited to the above-described example. The line-type overlapping identification pattern portion OIP_L can not be overlapped with the non-overlapping identification pattern portion NIP (e.g., the first non-overlapping identification pattern portion NIP1 and the second non-overlapping identification pattern portion NIP2) or the cut region CA in the second direction DR2.
[0170] In an embodiment (with reference to FIG. 1A), Figure 14 ), the line-type overlapping identification pattern portion OIP_L can include a protruding structure in a similar manner to the non-overlapping identification pattern portion NIP. For example, the line-type overlapping identification pattern portion OIP_L can include a portion protruding in a planar direction in some regions of the first conductive pattern layer CP1 and the second conductive pattern layer CP2. In this case, the line-type overlapping identification pattern portion OIP_L can have a shape extending in two or more directions. Accordingly, even when reflection of external light occurs in the line-type overlapping region OA_L, the line-type overlapping identification pattern portion OIP_L can change a reflection pattern of the external light and compensate for a difference in reflection of the external light. For example, in a plan view, the line-type overlapping identification pattern portion OIP_L can have a circular shape or an elliptical shape. However, the disclosure is not necessarily limited to the above-described example. In an embodiment, a size of the line-type overlapping identification pattern portion OIP_L can be greater than a size of the non-overlapping identification pattern portion NIP.
[0171] Alternatively, in an embodiment (with reference to FIG. 1A), Figure 15 ), the line-type overlapping identification pattern portion OIP_L can include a protruding structure similar to the protruding structure of the above-described dot-type overlapping identification pattern portion OIP_P. For example, the line-type overlapping identification pattern portion OIP_L can have a protrusion PRU protruding in two or more directions in the line-type overlapping region OA_L. In the line-type overlapping region OA_L, the protrusion PRU can extend in two or more different directions. In an embodiment, the above-described different directions can be different from the first direction DR1 and the second direction DR2. For example, the line-type overlapping identification pattern portion OIP_L can approximately have a diagonal shape (e.g., a “ / ” shape) and / or a backslash shape (e.g., a shape in which the left and right of “ / ” are reversed). In an embodiment, the line-type overlapping identification pattern portion OIP_L of the diagonal shape (e.g., a first line-type overlapping identification pattern portion) and the line-type overlapping identification pattern portion OIP_L of the backslash shape (e.g., a second line-type overlapping identification pattern portion) can be alternately disposed in a certain direction (e.g., the first direction DR1). However, the disclosure is not necessarily limited to the above-described example. For example, the line-type overlapping identification pattern portion OIP_L can have an approximate “X” shape.
[0172] Experimentally, in a case where the first conductive pattern layer CP1 and the second conductive pattern layer CP2 overlap in the linear overlapping area OA_L, the reflected light from the externally applied light in the linear overlapping area OA_L can have a relatively high light amount.
[0173] In an embodiment, in the linear overlapping area OA_L, the linear overlapping identification pattern portion OIP_L can be sequentially disposed along the overlapping area. Thus, the amount of the reflected light generated from the linear overlapping area OA_L can be reduced, thereby reducing the risk of perceiving the reflection of the external light in the linear overlapping area OA_L. Further, in an embodiment, since the size of the linear overlapping identification pattern portion OIP_L can be greater than the size of the non-overlapping identification pattern portion NIP, the amount of the light generated in the linear overlapping area OA_L can be further reduced.
[0174] Figure 18 FIG. 13 is a schematic view illustrating an embodiment in which the display device DD includes the non-overlapping identification pattern portion NIP corresponding to the cut area CA and includes both the point-type overlapping identification pattern portion OIP_P and the linear overlapping identification pattern portion OIP_L.
[0175] For example, the point-type overlapping identification pattern portion OIP_P can be formed in the point-type overlapping area OA_P of the overlapping area OA. The linear overlapping identification pattern portion OIP_L can be formed in the linear overlapping area OA_L of the overlapping area OA. In the present embodiment, the point-type overlapping identification pattern portion OIP_P can have the structure described above with reference to FIG. 10. Figures 10 to 13 The linear overlapping identification pattern portion OIP_L can have the structure described above with reference to FIG. 11. In an embodiment, the linear overlapping identification pattern portion OIP_L and the point-type overlapping identification pattern portion OIP_P can have different shapes. Figures 14 to 17
[0176] In the present embodiment, the reflection patterns of all external light corresponding to different types of overlapping areas OA can be compensated for. Thus, a display device DD having further increased visibility can be provided.
