[0115] The first sensing portions SP1 and the second sensing portions SP2 can be spaced apart from each other without overlapping each other and can be alternately disposed. A capacitance can be formed between the first sensing portions SP1 and the second sensing portions SP2. The extension patterns EP can not overlap the connection patterns CP.

[0116] Figure 7 is Figure 6An enlarged view of two adjacent first sensing portions and two adjacent second sensing portions shown in FIG. 1.

[0117] Referring to Figure 7 , the first sensing portion SP1 and the second sensing portion SP2 can have a mesh shape. To have the mesh shape, each of the first sensing portion SP1 and the second sensing portion SP2 can include a plurality of first branch portions BP1 extending in a first diagonal direction DDR1 and a plurality of second branch portions BP2 extending in a second diagonal direction DDR2.

[0118] The first diagonal direction DDR1 can be defined as a direction inclined from the first direction DR1 and the second direction DR2 on a plane defined by the first direction DR1 and the second direction DR2. The second diagonal direction DDR2 can be defined as a direction crossing the first diagonal direction DDR1 on the plane defined by the first direction DR1 and the second direction DR2. For example, the first direction DR1 and the second direction DR2 can cross each other at a right angle, and the first diagonal direction DDR1 and the second diagonal direction DDR2 can cross each other at a right angle.

[0119] The first branch portions BP1 and the second branch portions BP2 of each of the first sensing portion SP1 and the second sensing portion SP2 can cross each other and can be integrally formed with each other. A touch opening TOP having a rhombus shape can be defined by the first branch portions BP1 and the second branch portions BP2.

[0120] The emission areas LA can be disposed in the touch openings TOP when viewed from above. The light emitting elements OLED can be disposed in the emission areas LA. Each emission area LA can be Figure 5 the emission area LA shown in FIG. 1. The first sensing portion SP1 and the second sensing portion SP2 can be disposed in the non-emission area NLA. Since the first sensing portion SP1 and the second sensing portion SP2 are disposed in the non-emission area NLA, light transmitted from the emission area LA can pass through the input sensing portion ISP without being interrupted by the first sensing portion SP1 and the second sensing portion SP2.

[0121] The connection pattern CP can not overlap the extension pattern EP and can connect the first sensing portion SP1. The connection pattern CP can be connected to the first sensing portion SP1 through a plurality of contact holes TC-CH. The structure of the contact hole TC-CH will be described below with reference to Figure 8 The connection pattern CP can extend toward the first sensing portion SP1 and overlap the second sensing portion SP2.

[0122] The extension pattern EP can be disposed between the first sensing portions SP1 and can extend from the second sensing portion SP2. The second sensing portion SP2 and the extension pattern EP can be integrally formed with each other. The extension pattern EP can have a mesh shape.

[0123] The extension pattern EP, the first sensing portion SP1, and the second sensing portion SP2 can be disposed in the same layer and can be formed of the same material by the same patterning. The connection pattern CP can be disposed in a layer different from the layer in which the extension pattern EP, the first sensing portion SP1, and the second sensing portion SP2 are disposed.

[0124] The connection pattern CP can include a first connection pattern CP1 and a second connection pattern CP2 having shapes symmetrical to each other in the second direction DR2. The extension pattern EP can be disposed between the first connection pattern CP1 and the second connection pattern CP2. The first connection pattern CP1 and the second connection pattern CP2 can have a curved shape.

[0125] The first connection pattern CP1 can extend over one of the two second sensing portions SP2 to be connected to the first sensing portion SP1. The second connection pattern CP2 can extend over the other of the two second sensing portions SP2 to be connected to the first sensing portion SP1.

[0126] The contact hole TC-CH can be formed in regions adjacent to both ends of the first connection pattern CP1 and in regions adjacent to both ends of the second connection pattern CP2. The contact hole TC-CH can overlap the first sensing portion SP1 when viewed from above. The first connection pattern CP1 and the second connection pattern CP2 can be connected to the first sensing portion SP1 through the contact hole TC-CH.

[0127] The curved portion (not shown) of the first connection pattern CP1 and the curved portion (not shown) of the second connection pattern CP2 can overlap the second sensing portion SP2, respectively. A single touch opening TOP can be defined in each of the curved portion of the first connection pattern CP1 and the curved portion of the second connection pattern CP2. Each of the first connection pattern CP1 and the second connection pattern CP2 can include two mesh lines (not shown) extending toward the first sensing portion SP1.

[0128] Figure 8 is a cross-sectional view taken along the line I-I' shown in Figure 7

[0129] Referring to Figure 7 and Figure 8 ​The base layer BSL can be disposed on the thin film encapsulation layer TFE. The connection pattern CP can be disposed on the base layer BSL. The first insulating layer T-INS1 can be disposed on the connection pattern CP and the base layer BSL. The first insulating layer T-INS1 can be disposed on the base layer BSL to cover the connection pattern CP. The first insulating layer T-INS1 can include an organic insulating layer.

[0130] The first sensing part SP1 and the second sensing part SP2 can be disposed on the first insulating layer T-INS1. The extension pattern EP integrally formed with the second sensing part SP2 can also be disposed on the first insulating layer T-INS1. The connection pattern CP can be connected to the first sensing part SP1 through a plurality of contact holes TC-CH defined in the first insulating layer T-INS1.

[0131] The extension pattern EP, the first sensing part SP1, and the second sensing part SP2 can be disposed on the first insulating layer T-INS1 or can be disposed in the same layer. The connection pattern CP can be disposed below the extension pattern EP, the first sensing part SP1, and the second sensing part SP2 or can be disposed in a different layer from the extension pattern EP, the first sensing part SP1, and the second sensing part SP2.

[0132] The second insulating layer T-INS2 can be disposed on the first sensing part SP1 and the second sensing part SP2 and the first insulating layer T-INS1. The second insulating layer T-INS2 can include an organic insulating layer.

[0133] Figure 9 is Figure 6 an enlarged view of the first area AA1 shown in FIG. 2B.

[0134] Referring to Figure 6 and Figure 9 , the non-active area NAA can include a first side area NAA1 and a second side area NAA2 adjacent to left and right sides of the active area AA, respectively, in the second direction DR2. The first area AA1 is an enlarged view of a partial area of the first side area NAA1.

[0135] Referring to Figure 9 , the second lines RX can extend in the first direction DR1 and can be arranged in the second direction DR2. For convenience of description, the serial numbers (e.g., 1 to k in RX1 to RXk) for the second lines RX are omitted in Figure 9 .

[0136] A plurality of first contact portions CTP1 can be defined on each of the second lines RX. The first contact portions CTP1 can be arranged on each of the second lines RX in the first direction DR1. For example, the first contact portions CTP1 can have a quadrilateral shape and are illustrated by dotted lines. Figure 9The first contact portion CTP1 shown can be formed on a surface such as... Figure 6 The second line RL1 to RLk in the first side region NAA1 and the second side region NAA2 shown in the figure.

[0137] Figure 10 yes Figure 9 An enlarged view of one of the first contact portions shown.

[0138] Reference Figure 10 The first contact portion CTP1 may include a plurality of first contact holes CTH1. The first contact holes CTH1 may be arranged in a matrix. For example, the first contact holes CTH1 may be arranged in a first direction DR1 and a second direction DR2. For example, the first contact holes CTH1 may have a circular shape. However, the shape of the first contact holes CTH1 is not limited to this.

[0139] Figure 11 yes Figure 10 The diagram shows an enlarged view of the first region BB1, and also shows the detailed shape of the first contact hole and the detailed arrangement of the lines disposed on the first contact hole. Figure 12 It is along Figure 11 The sectional view shown is taken from line II-II'. Figure 13 It is along Figure 11 The sectional view shown is taken from line III-III'.

[0140] Reference Figure 11 , Figure 12 and Figure 13 The second line RX may include a second-first line L2-1 and a second-second line L2-2 disposed on the second-first line L2-1. The second-first line L2-1 may be disposed on the base layer BSL. A first insulating layer T-INS1 may be disposed on the second-first line L2-1 and the base layer BSL. The second-second line L2-2 may be disposed on the first insulating layer T-INS1. Therefore, the first insulating layer T-INS1 may be disposed between the second-first line L2-1 and the second-second line L2-2.

[0141] The second-first line L2-1 can be disposed in the same layer as the connecting pattern CP. The second-first line L2-1 and the connecting pattern CP can be formed using the same patterning and the same material. The second-second line L2-2 can be disposed in the same layer as the first sensing part SP1, the second sensing part SP2, and the extension pattern EP as described above. The second-second line L2-2, the first sensing part SP1, the second sensing part SP2, and the extension pattern EP can be formed using the same patterning and the same material.

[0142] In a region other than the first contact hole CTH1, the thickness of the first insulating layer T-INS1 in the third direction DR3 can be 1.5 times to 20 times the thickness of the second-first line L2-1 in the third direction DR3. The third direction DR3 can be defined as a direction perpendicular to the upper surface of the first insulating layer T-INS1. The second-first line L2-1 and the second-second line L2-2 can have the same thickness. For example, each of the second-first line L2-1 and the second-second line L2-2 can have a thickness of about 1 μm to 10 μm.

[0143] The second-second line L2-2 can be electrically connected to the second-first line L2-1 through the first contact hole CTH1 formed in the first insulating layer T-INS1. Since each second line RX includes the second-first line L2-1 and the second-second line L2-2 electrically connected to each other, the electrical resistance of each second line RX can be reduced. That is, since such a multi-layer structure, the electrical resistance of each of the second lines RX1 to RXk shown in FIG. 1 can be reduced. Figure 6

[0144] The inner surface of the first insulating layer T-INS1 defining the first contact hole CTH1 can have a first inclined surface SLP1. The first contact hole CTH1 can be defined as an internal space surrounded by the first inclined surface SLP1.

[0145] The first contact hole CTH1 can include a first hole H1 in which a portion of the second-first line L2-1 connected to the second-second line L2-2 is disposed. The second-second line L2-2 can be disposed on the upper surface of the first insulating layer T-INS1 and the first inclined surface SLP1. The second-second line L2-2 can extend to the first hole H1 and can contact the portion of the second-first line L2-1 disposed in the first hole H1.

[0146] The first inclined surface SLP1 can form an acute angle with the lower surface of the first insulating layer T-INS1 and can form an obtuse angle with the upper surface of the first insulating layer T-INS1. For example, the angle between the first inclined surface SLP1 and the lower surface of the first insulating layer T-INS1 can be in the range of 10 degrees to 89 degrees.

[0147] The second-second line L2-2 can define a first-first opening OP1-1 corresponding to a first-first portion P1-1 of the first inclined surface SLP1 and a first-second opening OP1-2 corresponding to a first-second portion P1-2 of the first inclined surface SLP1. In other words, the first-first opening OP1-1 and the first-second opening OP1-2 can be defined in each first contact portion CTP1.

[0148] ​​The first-first opening OP1-1 and the first-second opening OP1-2 can be arranged in the second direction DR2. The first-first opening OP1-1 and the first-second opening OP1-2 can have shapes symmetrical to each other in the second direction DR2. For example, the first-first opening OP1-1 and the first-second opening OP1-2 can have a sector shape when viewed from above. However, the shapes of the first-first opening OP1-1 and the first-second opening OP1-2 are not limited thereto.

[0149] Each of the first-first opening OP1-1 and the first-second opening OP1-2 can not overlap the first hole H1 when viewed from above. Each of the first-first opening OP1-1 and the first-second opening OP1-2 can extend to a portion of an upper surface of the first insulating layer T-INS1 adjacent to the first inclined surface SLP1. However, not limited thereto, each of the first-first opening OP1-1 and the first-second opening OP1-2 can correspond to only the first inclined surface SLP1.

[0150] The second insulating layer T-INS2 can be disposed on the second-second line L2-2. The second insulating layer T-INS2 can fill the first contact hole CTH1. In addition, the second insulating layer T-INS2 can fill the first-first opening OP1-1 and the first-second opening OP1-2. In an area other than the first contact hole CTH1, the second insulating layer T-INS2 can have the same thickness as the first insulating layer T-INS1.

[0151] The first contact portion CTP1 defined on the second line RX1 to RXk disposed in the first side area NAA1 and the second side area NAA2 in Figure 6 may have a structure as shown in Figure 10 to Figure 13 .

[0152] Figure 14 is a view showing light reflected from the second line when the second line is disposed on the first inclined surface. Figure 15 is a view showing a rainbow band that can be detected from the second line.

[0153] Referring to Figure 14 and Figure 15 , the second-second line L2-2 can include two first electrodes E1 and a second electrode E2 disposed between the first electrodes E1. The first electrodes E1 can include the same metal material. The second electrode E2 can include a metal material different from the metal material of the first electrode E1. For example, the first electrode E1 can include titanium (Ti), and the second electrode E2 can include aluminum (Al). The second electrode E2 can be thicker than the first electrode E1.

[0154] The first light LT1 can be directed to the second-second line L2-2 above the planar upper surface of the first insulating layer T-INS1. The second light LT2 can be directed to the second-second line L2-2 above the first inclined surface SLP1. The first light LT1 and the second light LT2 can form the same angle with respect to the third direction DR3 and can be directed to the second-second line L2-2.

[0155] A portion of the first light LT1 can be reflected from the upper surface of the first electrode E1 disposed on the second electrode E2. A portion of the first light LT1 can pass through the first electrode E1 and can be reflected from the upper surface of the second electrode E2. The light of the first light LT1 reflected from the first electrode E1 can be referred to as first-first light LT1-1, and the light of the first light LT1 reflected from the second electrode E2 can be referred to as first-second light LT1-2.

[0156] A portion of the second light LT2 can be reflected from the upper surface of the first electrode E1 disposed on the second electrode E2. A portion of the second light LT2 can pass through the first electrode E1 and can be reflected from the upper surface of the second electrode E2. The light of the second light LT2 reflected from the first electrode E1 can be referred to as second-first light LT2-1, and the light of the second light LT2 reflected from the second electrode E2 can be referred to as second-second light LT2-2.

[0157] A distance that the first light LT1 travels from the upper surface of the first electrode E1 to the upper surface of the second electrode E2 can be referred to as a first distance DT1. A distance that the second light LT2 travels from the upper surface of the first electrode E1 to the upper surface of the second electrode E2 can be referred to as a second distance DT2.

[0158] The second-second line L2-2 can be disposed on the upper surface of the first insulating layer T-INS1 having a planar surface in a planar state. The second-second line L2-2 can be disposed on the first inclined surface SLP1 and can be arranged to have an inclined surface.

[0159] An angle formed by the first light LT1 with the planar upper surface of the second-second line L2-2 can be greater than an angle formed by the second light LT2 with the inclined surface of the second-second line L2-2. Due to the difference in the incident angle, the second distance DT2 can be greater than the first distance DT1.

[0160] According to the first distance DT1, the first-second light LT1-2 can be reflected later than the first-first light LT1-1, and thus the phase of the first-second light LT1-2 can be delayed compared to the phase of the first-first light LT1-1. According to the second distance DT2, the second-second light LT2-2 can be reflected later than the second-first light LT2-1, and thus the phase of the second-second light LT2-2 can be delayed compared to the phase of the second-first light LT2-1.

[0161] Since the second distance DT2 is greater than the first distance DT1, the second-second light LT2-2 can be reflected later than the first-second light LT1-2. Thus, the phase difference between the second-first light LT2-1 and the second-second light LT2-2 can be greater than the phase difference between the first-first light LT1-1 and the first-second light LT1-2.

[0162] The greater the phase difference, the greater the possibility of destructive interference and constructive interference of light between the second-first light LT2-1 and the second-second light LT2-2. When significant destructive interference and constructive interference occur, light of a specific wavelength in a specific color range can be enhanced or attenuated due to such interference, causing the reflected light to become light of a specific color.

[0163] Due to such a phenomenon, light reflected from the second-second line L2-2 on the first inclined surface SLP1 defining the first contact hole CTH1 can appear as a specific color. Since the first contact portion CTP1 including the first contact hole CTH1 is disposed in the first direction DR1, as shown in Figure 15 , the light of a specific color generated from the first contact hole CTH1 can appear as a rainbow color band RIW extending in the first direction DR1.

[0164] When the user obliquely observes the input sensing part ISP from the left and right sides in the second direction DR2, the above-described rainbow color band RIW can be observed. In other words, the rainbow color band RIW can be visible when the first side area NAA1 and the second side area NAA2 are observed from the left and right sides in the second direction DR2.

[0165] In Figure 14 , the first inclined surface SLP1 on the left in the second direction DR2 is shown as an example. However, the above-described phenomenon can occur when light is reflected from the second-second line L2-2 disposed on a portion of the first inclined surface SLP1 provided on the right side. In other words, the above-described phenomenon can occur when light is reflected from the second-second line L2-2 disposed on portions of the first inclined surface SLP1 facing each other in the second direction DR2.

[0166] Referring to Figure 11 to Figure 13The portions of the second-first lines L2-1 disposed on the portions of the first inclined surface SLP1 facing each other in the second direction DR2 can be removed by defining the first-first openings OP1-1 and the first-second openings OP1-2. Accordingly, light can not be reflected from the portions of the first inclined surface SLP1 facing each other in the second direction DR2. As a result, the rainbow band RIW caused by the light reflection can not occur.

[0167] Figure 16 is Figure 6 is a close-up view of the second area AA2 shown in FIG. 11B.

[0168] Referring to Figure 6 and Figure 16 , the non-active area NAA can include a lower area NAA3 adjacent to the active area AA in the first direction DR1. Some portions of the first lines TX1 to TXh and the second lines RX1 to RXk can be disposed in the lower area NAA3. The second area AA2 is a close-up view of a partial area of the lower area NAA3.

[0169] Referring to Figure 16 , the first lines TX can extend in the first direction DR1 and can be arranged in the second direction DR2. For convenience of description, the serial numbers (e.g., 1 to h in TX1 to TXh) for the first lines TX are omitted in Figure 16 .

[0170] A plurality of second contact portions CTP2 can be defined on each of the first lines TX. The second contact portions CTP2 can be arranged on each of the first lines TX in the first direction DR1. The second contact portions CTP2 can have a quadrilateral shape and are illustrated by dotted lines. Figure 16 The second contact portions CTP2 shown in FIG. 11B can be formed on some of the first lines TX1 to TXh and the second lines RX1 to RXk disposed in the lower area NAA3 as shown in Figure 6 .

[0171] Figure 17 is Figure 16 is a close-up view of one of the second contact portions shown in FIG. 11B.

[0172] Referring to Figure 17 , the second contact portions CTP2 can include a plurality of second contact holes CTH2. The second contact holes CTH2 can be arranged in the first direction DR1 and the second direction DR2 and can be arranged in a matrix form. When viewed from above, the second contact holes CTH2 can have substantially the same shape as the first contact holes CTH1.

[0173] Figure 18 is Figure 17An enlarged view of the second region BB2 is shown, and detailed shapes of the second contact holes and detailed arrangements of the lines provided on the second contact holes are shown. Figure 19 is a cross-sectional view taken along the line IV-IV' shown in Figure 18 . Figure 20 is a cross-sectional view taken along the line V-V' shown in Figure 18 .

[0174] Referring to Figure 17 , Figure 18 and Figure 19 , the first lines TX can include first-first lines L1-1 and first-second lines L1-2 provided on the first-first lines L1-1. The first-first lines L1-1 can be provided on the base layer BSL, and a first insulating layer T-INS1 can be provided on the first-first lines L1-1 and the base layer BSL.

[0175] The first-second lines L1-2 can be provided on the first insulating layer T-INS1. Accordingly, the first insulating layer T-INS1 can be provided between the first-first lines L1-1 and the first-second lines L1-2. A second insulating layer T-INS2 can be provided on the first-second lines L1-2 and the first insulating layer T-INS1.

[0176] The first-first lines L1-1 can be provided on the same layer as the first-second lines L2-1, and the first-second lines L1-2 can be provided on the same layer as the second-second lines L2-2. The first-first lines L1-1 and the first-second lines L1-2 can have the same thickness as the second-first lines L2-1 and the second-second lines L2-2.

[0177] The first-second lines L1-2 can be electrically connected to the first-first lines L1-1 through second contact holes CTH2 defined in the first insulating layer T-INS1. The second contact holes CTH2 can have substantially the same configuration as the above-described first contact holes CTH1. Since the first-first lines L1-1 and the first-second lines L1-2 are electrically connected to each other, the electrical resistance of each of the first lines TX1 to TXh can be reduced.

[0178] An inner surface of the first insulating layer T-INS1 defining the second contact holes CTH2 can have a second inclined surface SLP2. The second contact holes CTH2 can include second holes H2 in which portions of the first-first lines L1-1 connected to the first-second lines L1-2 are provided. The first-second lines L1-2 can contact the portions of the first-first lines L1-1 provided in the second holes H2. An angle between the second inclined surface SLP2 and a lower surface of the first insulating layer T-INS1 can be in a range of 10 degrees to 89 degrees.

[0179] The first-second line L1-2 can define a second-first opening OP2-1 corresponding to the second-first portion P2-1 of the second inclined surface SLP2. Also, the first-second line L1-2 can define a second-second opening OP2-2 corresponding to the second-second portion P2-2 of the second inclined surface SLP2. In other words, the second-first opening OP2-1 and the second-second opening OP2-2 can be defined in each of the second contact portions CTP2.

[0180] The second-first opening OP2-1 and the second-second opening OP2-2 can be arranged in the first direction DR1. The second-first opening OP2-1 and the second-second opening OP2-2 can have shapes symmetrical to each other in the first direction DR1.

[0181] When viewed from above, the second-first opening OP2-1 and the second-second opening OP2-2 can have a sector shape. However, the shapes of the second-first opening OP2-1 and the second-second opening OP2-2 are not limited thereto. In other words, the second-first opening OP2-1 and the second-second opening OP2-2 can have substantially the same shapes as the first-first opening OP1-1 and the first-second opening OP1-2, although the arrangement directions are different.

[0182] When viewed from above, the second-first opening OP2-1 and the second-second opening OP2-2 can extend to a portion of an upper surface of the first insulating layer T-INS1 adjacent to the second inclined surface SLP2 without overlapping the second hole H2. However, not limited thereto, each of the second-first opening OP2-1 and the second-second opening OP2-2 can correspond to the second inclined surface SLP2 only.

[0183] The first lines TX1 to TXh defined in Figure 6 and the second contact portions CTP2 disposed on some portions of the second lines RX1 to RXk in the lower area NAA3 can have structures as shown in Figure 17 to Figure 20 .

[0184] The phenomena described above with reference to Figure 14 and Figure 15 may also occur on the second contact hole CTH2. For example, when light incident to the lower area NAA3 of the input sensing part ISP in the first direction DR1 is reflected from the second inclined surface SLP2, a rainbow band can be observed. In other words, the rainbow band can be visible when light is reflected from portions of the second inclined surface SLP2 facing each other in the first direction DR1.

[0185] In an embodiment of the present disclosure, the portions of the first-second lines L1-2 provided on portions of the second inclined surface SLP2 facing each other in the first direction DR1 can be removed by defining the second-first openings OP2-1 and the second-second openings OP2-2. Accordingly, light can not be reflected from the portions of the second inclined surface SLP2 facing each other in the first direction DR1. As a result, a rainbow band caused by light reflection can not occur.

[0186] Referring to Figure 6 , Figure 10 to Figure 14 and Figure 17 to Figure 20 , some portions of the second lines RX1 to RXk can be provided in a corner area CNA of a lower portion of the input sensing part ISP. Contact portions (not shown) can be defined on the second lines provided in the corner area CNA, and contact holes (not shown) in the contact portions can have substantially the same configuration as the first contact holes CTH1 and the second contact holes CTH2 shown in Figure 11 to Figure 13 or Figure 18 to Figure 20 .

[0187] Although not shown, the first-first openings OP1-1 and the first-second openings OP1-2 shown in Figure 11 to Figure 13 may be defined in the second-second lines L2-2 provided on the contact holes of the second lines L2 provided in the corner area CNA. However, the present disclosure is not limited thereto, and the second-first openings OP2-1 and the second-second openings OP2-2 shown in Figure 18 to Figure 20 may be defined in the second-second lines L2-2 provided on the contact holes of the second lines L2 provided in the corner area CNA.

[0188] Figure 21A and Figure 21B are views showing shapes of openings defined on a first inclined surface according to an embodiment of the present disclosure.

[0189] Figure 21A and Figure 21B are plan views corresponding to Figure 11 . The following description will focus on differences between elements shown in Figure 11 and elements shown in Figure 21A and Figure 21B .

[0190] Referring to Figure 21A and Figure 21B , unlike in Figure 11 , only one of the first-first openings OP1-1 and the first-second openings OP1-2 can be defined in the second-second lines L2-2. For example, as shown in Figure 21A , only the first-first openings OP1-1 can be defined in the second-second lines L2-2, or as shown in Figure 21BAs shown in FIG. 1B, only the first-second opening OP1-2 can be defined in the second-second line L2-2.

[0191] Figure 22A and Figure 22B are views showing shapes of openings defined on a second inclined surface according to an embodiment of the disclosure.

[0192] Figure 22A and Figure 22B are plan views corresponding to Figure 18 The following description will focus on differences between elements shown in Figure 18 and elements shown in Figure 22A and Figure 22B

[0193] Referring to Figure 22A and Figure 22B , unlike in Figure 18 , only one of the second-first opening OP2-1 and the second-second opening OP2-2 can be defined in the first-second line L1-2. For example, as shown in Figure 22A , only the second-first opening OP2-1 can be defined in the first-second line L1-2, or as shown in Figure 22B , only the second-second opening OP2-2 can be defined in the first-second line L1-2.

[0194] Figure 23 are views showing shapes of openings defined on a first inclined surface according to an embodiment of the disclosure.

[0195] Figure 23 are plan views corresponding to Figure 11 The following description will focus on differences between elements shown in Figure 11 and elements shown in Figure 23

[0196] Referring to Figure 23 , the first-third opening OP1-3 corresponding to the first-third portion P1-3 of the first inclined surface SLP1 and the first-fourth opening OP1-4 corresponding to the first-fourth portion P1-4 of the first inclined surface SLP1 can be additionally defined in the second-second line L2-2.

[0197] ​​The first-first opening OP1-1 and the first-second opening OP1-2 can be arranged in the second direction DR2, and the first hole H1 is between the first-first opening OP1-1 and the first-second opening OP1-2. The first-third opening OP1-3 and the first-fourth opening OP1-4 can be arranged in the first direction DR1, and the first hole H1 is between the first-third opening OP1-3 and the first-fourth opening OP1-4. The second direction DR2 can be defined as one direction, and the first direction DR1 can be defined as another direction crossing the one direction.

[0198] Figure 24 is a view showing a shape of an opening defined on a second inclined surface according to an embodiment of the present disclosure.

[0199] Figure 24 is a plan view corresponding to Figure 18 . The following description will focus on the difference between the elements shown in Figure 18 and the elements shown in Figure 24 .

[0200] Referring to Figure 24 , a second-third opening OP2-3 corresponding to a second-third portion P2-3 of the second inclined surface SLP2 and a second-fourth opening OP2-4 corresponding to a second-fourth portion P2-4 of the second inclined surface SLP2 can be additionally defined in the first-second line L1-2.

[0201] The second-first opening OP2-1 and the second-second opening OP2-2 can be arranged in the first direction DR1, and the second hole H2 is between the second-first opening OP2-1 and the second-second opening OP2-2. The second-third opening OP2-3 and the second-fourth opening OP2-4 can be arranged in the second direction DR2, and the second hole H2 is between the second-third opening OP2-3 and the second-fourth opening OP2-4.

[0202] Figure 25 is a view showing a character formed using a contact portion according to an embodiment of the present disclosure.

[0203] Referring to Figure 25 , a plurality of first-first contact portions CTP1-1 and a plurality of first-second contact portions CTP1-2 can be defined on the first line RX. The first-first contact portions CTP1-1 can be the above-described first contact portions CTP1. In other words, the first-first contact portions CTP1-1 can define the first-first opening OP1-1 and the first-second opening OP1-2. In contrast, the first-second contact portions CTP1-2 can not define the first-first opening OP1-1 and the first-second opening OP1-2.

[0204] The first-second contact portion CTP1-2 can be arranged in the form of a specific character. For example, the first-second contact portion CTP1-2 can be arranged in the form of an "A". The first-first contact portion CTP1-1 can be disposed around the first-second contact portion CTP1-2.

[0205] The first-first contact portion CTP1-1 in which the first-first opening OP1-1 and the first-second opening OP1-2 are defined and the first-second contact portion CTP1-2 in which the first-first opening OP1-1 and the first-second opening OP1-2 are not defined can have different light transmittances according to whether the openings are defined. Accordingly, the first-first contact portion CTP1-1 and the first-second contact portion CTP1-2 can be distinguished from each other. As a result, the first-second contact portion CTP1-2 is arranged in the shape of an "A" character, thereby allowing the user to discern the "A" character.

[0206] Although the letter "A" is shown as an example, embodiments of the present disclosure are not limited thereto. The first-second contact portion CTP1-2 can be arranged in the form of various characters, and the various characters can be visible to the user.

[0207] According to embodiments of the present disclosure, at least one opening can be defined in each of the first-second line L1-2 and the second-second line L2-2 in a position corresponding to the inner surface of the defined contact hole of the insulating layer. Since the first-second line L1-2 and the second-second line L2-2, which can reflect light, are not disposed on the inner surface of the insulating layer, a rainbow band shape generated due to light reflection can not occur.

[0208] Although the present disclosure has been described with reference to embodiments thereof, it is apparent to those skilled in the art that various changes and modifications can be made thereto without departing from the spirit and scope of the present disclosure as set forth in the appended claims.
