[0044] refer to Figure 1 According to an embodiment of the present disclosure, the display device DD may have a rectangular shape having a longer side extending in a first direction DR1 and a shorter side extending in a second direction DR2 crossing the first direction DR1. However, the embodiment is not limited thereto, and the display device DD may have various shapes such as a circle or other polygons other than a rectangle. The first direction DR1 and the second direction DR2 are substantially perpendicular to each other while crossing each other.
[0045] Hereinafter, a direction substantially perpendicular to a plane defined by the first direction DR1 and the second direction DR2 is a third direction DR3. In this specification, the meaning of "when viewed in a plan view" or "when viewed on a plane" may mean "when viewed in the third direction DR3".
[0046] The top surface of the display device DD may be referred to as a display surface DS, and may have a plane defined by the first direction DR1 and the second direction DR2. An image IM generated by the display device DD may be provided to a user through the display surface DS.
[0047] The display surface DS may include a display area DA and a non-display area NDA around the display area DA. The display area DA is intended to display an image, while the non-display area NDA does not display an image. The non-display area NDA may be an edge of the display device DD surrounding the display area DA and printed with a specific color.
[0048] The display device DD may be used for large electronic devices such as televisions, monitors, or external billboards. In addition, the display device DD may be used for small and medium-sized display devices such as personal computers, laptop computers, personal digital terminals, car navigation systems, game consoles, smart phones, tablet computers, or cameras. However, the types of display devices DD are provided for illustrative purposes only. The display device DD may be applied to other electronic devices as long as it does not deviate from the concept of the present disclosure.

When manufacturing the display device DD, the anti-reflection layer RPL may be disposed on the input sensing portion ISP. However, the present disclosure is not limited thereto. The anti-reflection layer RPL may be manufactured using an additional panel and attached to the input sensing portion ISP through an adhesive layer.
[0055] The anti-reflection layer RPL may be a film that prevents external light from being reflected.

The second sensing electrodes SE2 may be insulated from the first sensing electrodes SE1 and extend to cross over the first sensing electrodes SE1. The first sensing electrodes SE1 may be transmission electrodes, and the second sensing electrodes SE2 may be reception electrodes.
[0142] The lines TX1 to TXi and RX1 to RXj may include a plurality of first lines TX1 to TXi connected to the first sensing electrode SE1 and a plurality of second lines RX1 to RXj connected to the second sensing electrode SE2. In this case, "i" and "j" are natural numbers greater than 0. The first lines TX1 to TXi may extend to the non-active area NAA and may be connected to the second pad PD2. The second lines RX1 to RXj may extend to the non-active area NAA and may be connected to the third pad PD3.

[0147] Fig. 9 yes Figure 8 FIG. 1 is an enlarged view of two first sensing portions adjacent to each other and two second sensing portions adjacent to each other. Fig.10 It is shown Fig. 9 A view of the connection pattern shown. Fig.11 It is shown Fig. 9 A view of the first and second sensing portions and the extended pattern is shown.
[0148] refer to Fig. 9 , each of the first sensing part SP1 and the second sensing part SP2 may include a plurality of mesh lines MSL and a plurality of conductive patterns CTP. In each of the first sensing part SP1 and the second sensing part SP2, the mesh lines MSL and the conductive patterns CTP may be integrally formed.
[0149] The mesh lines MSL may extend from the conductive pattern CTP in the first and second diagonal directions DDR1 and DDR2 and in the second direction DR2. A space surrounded by the mesh lines MSL and the conductive pattern CTP may be referred to as a touch opening TOP.
[0150] When viewed in a plan view, the light emitting area LEA may be disposed in the touch opening TOP. Each of the light emitting areas LEA may be Figure 5 , Figure 6 and Figure 7 For ease of explanation, the light emitting area LEA is shown. Fig. 9 Only three light emitting areas LEA adjacent to each other are shown by dotted lines in FIG. 4 ; however, each of the touch openings TOP includes a light emitting area LEA.
[0151] When viewed in a plan view, the mesh line MSL and the conductive pattern CTP may overlap the non-light emitting area NLEA without overlapping the light emitting area LEA. Therefore, when viewed in a plan view, the first sensing part SP1 and the second sensing part SP2 may overlap the non-light emitting area NLEA without overlapping the light emitting area LEA.
[0152] Since the first and second sensing parts SP1 and SP2 are disposed in the non-light emitting area NLEA, light may be normally emitted from the light emitting area LEA without being affected by the first and second sensing parts SP1 and SP2.
[0153] The extension pattern EP and the connection pattern CP may include a mesh line MSL and a conductive pattern CTP overlapping the non-light emitting area NLEA and not overlapping the light emitting area LEA like the first and second sensing parts SP1 and SP2 .
[0154] When viewed in a plan view, the mesh line MSL and the conductive pattern CTP may be disposed between the first light emitting element OLED1, the second light emitting element OLED2, and the third light emitting element OLED3. Fig.13A Detailed arrangement structures of the mesh lines MSL and the conductive patterns CTP for the first, second, and third light emitting elements OLED1, OLED2, and OLED3 are described in FIG.
[0155] refer to Fig. 9 , Fig.10 and Fig.11 , the extension pattern EP and the first and second sensing parts SP1 and SP2 may be disposed in a different layer from the connection pattern CP. For example, the connection pattern CP may be disposed on the thin film encapsulation layer TFE described above, and the extension pattern EP and the first and second sensing parts SP1 and SP2 may be disposed on the connection pattern CP. The extension pattern EP, the first and second sensing parts SP1 and SP2 may be disposed in the same layer and may be formed by patterning the same material at the same time.
[0156] The connection pattern CP may include a first extension portion EX1 and a second extension portion EX2 extending in the first direction DR1 and spaced apart from each other in the second direction DR2. The first extension portion EX1 and the second extension portion EX2 may have substantially the same shape. Both sides of the first extension portion EX1 and the second extension portion EX2 opposite to each other in the first direction DR1 may overlap the first sensing portion SP1.
[0157] The first extension part EX1 and the second extension part EX2 may be connected to the first sensing part SP1 through a plurality of touch contact holes T-CH overlapping the first sensing part SP1. The touch contact holes T-CH may overlap some of the conductive patterns CTP of the first sensing part SP1. Fig.12 , a cross-sectional structure of the touch contact hole T-CH is shown in FIG.
[0158] The extension pattern EP may be disposed between the first sensing portions SP1 and may extend from the second sensing portion SP2 in the second direction DR2. The extension pattern EP may be formed integrally with the second sensing portion SP2. When viewed in a plan view, the extension pattern EP may extend to intersect the connection pattern CP. An insulating layer is interposed between the extension pattern EP and the connection pattern CP so that the extension pattern EP and the connection pattern CP may be insulated from each other.
[0159] The first sensing portion SP1 may be separated from the second sensing portion SP2 and the extension pattern EP. For example, a separation portion between the first sensing portion SP1 and the second sensing portion SP2 and a separation portion between the first sensing portion SP1 and the extension pattern EP are located at Fig.11 Indicated by dotted lines.
[0160] Fig.12 It is along Fig. 9 A cross-sectional view taken along line II' is shown.
[0161] refer to Fig.12 , the base layer BSL may be disposed on the thin film encapsulation layer TFE. The connection pattern CP may be disposed on the base layer BSL. The first touch insulating layer T-INS1 may be disposed on the connection pattern CP and the base layer BSL. The first touch insulating layer T-INS1 may be disposed on the base layer BSL to cover the connection pattern CP. The first touch insulating layer T-INS1 may include an inorganic insulating layer or an organic insulating layer.
[0162] The first sensing part SP1 and the extension pattern EP may be disposed on the first touch insulating layer T-INS1. The second sensing part SP2 integrally formed with the extension pattern EP may also be disposed on the first touch insulating layer T-INS1. The connection pattern CP may be connected to the first sensing part SP1 through a plurality of touch contact holes T-CH defined in the first touch insulating layer T-INS1.
[0163] The second touch insulation layer T-INS2 may be disposed on the first sensing part SP1, the extension pattern EP, and the first touch insulation layer T-INS1. The second touch insulation layer T-INS2 may include an organic insulation layer.
[0164] Fig.13A yes Fig. 9 An enlarged view of a local area of any one of the first sensing portion and the second sensing portion is shown. Fig. 13B is with Fig.13A The corresponding enlarged view is a view showing another shape of the conductive pattern.
[0165] refer to Fig.13A , when viewed in a plan view, the mesh line MSL may be interposed between the first light emitting element OLED1 and the second light emitting element OLED2 , between the first light emitting element OLED1 and the third light emitting element OLED3 , and between the second light emitting element OLED2 and the third light emitting element OLED3 .
[0166] When viewed in a plan view, the conductive pattern CTP may be interposed between the third light emitting elements OLED3 disposed in at least one column. As described above, since the third light emitting elements OLED3 are disposed in the even columns C_E, the conductive pattern CTP may be interposed between the third light emitting elements OLED3 disposed in at least one even column C_E. The grid line MSL may extend from the conductive pattern CTP and may be formed integrally with the conductive pattern CTP.
[0167] The conductive pattern CTP may be arranged in the first direction DR1 and the second direction DR2. In other words, the conductive pattern CTP may be arranged in a plurality of rows corresponding to the second direction DR2 and in a plurality of columns corresponding to the first direction DR1. For example, each of the plurality of rows may extend in the second direction DR2, and each of the plurality of columns may extend in the first direction DR1. As for the third light emitting element OLED3, the third light emitting element OLED3 may also be arranged in a plurality of rows corresponding to the second direction DR2 and in a plurality of columns corresponding to the first direction DR1.
[0168] For example, the conductive pattern CTP is inserted between the third light emitting elements OLED3 disposed in all even columns C_E, but the embodiments of the present disclosure are not limited thereto. For example, the conductive pattern CTP may be inserted only between the third light emitting elements OLED3 disposed in some even columns C_E.
[0169] The width of each of the conductive patterns CTP may be greater than the width of each of the mesh lines MSL. The width of each of the mesh lines MSL may be a value measured in a direction perpendicular to an extending direction of each of the mesh lines MSL.
[0170] like Fig.13A As shown in FIG. 1 , the conductive pattern CTP may have a circular shape when viewed in a plan view, but the shape of the conductive pattern CTP is not limited thereto. Fig. 13B As shown, the conductive pattern CTP' may have a polygonal shape. Fig.13A As shown, when the conductive patterns CTP have a circular shape, the width of each of the conductive patterns CTP may be the diameter of each of the conductive patterns CTP.
[0171] like Fig. 13B As shown, when the conductive pattern CTP' has a polygonal shape, the width of each of the conductive patterns CTP' may be a value measured in a direction perpendicular to one side of the polygon. Fig. 13B The conductive pattern CTP' shown may have a hexagonal shape. In this case, the width of each of the conductive patterns CTP' may be a value measured in a first direction DR1 perpendicular to the sides of the conductive pattern CTP', a first diagonal direction DDR1, and a second diagonal direction DDR2.
[0172] As described above, the distance between adjacent third light emitting elements OLED3 may be the third distance GP3 and may be greater than the first distance GP1 and the second distance GP2. Therefore, the conductive pattern CTP may be provided as a conductor having a larger width between the third light emitting elements OLED3. In other words, according to an embodiment of the present disclosure, the grid line MSL may not be provided between the third light emitting elements OLED3, and the conductive pattern CTP having a larger width may be provided between the third light emitting elements OLED3.
[0173] Since the mesh line MSL is not provided between the third light emitting element OLED3 and a conductive pattern CTP having a larger width is used instead, the area of the conductor of each of the first sensing part SP1 and the second sensing part SP2 can be increased. The capacitance is proportional to the area of the conductor, so increasing the capacitance can improve the touch sensitivity.
[0174] According to an embodiment of the present disclosure, since each of the first sensing part SP1 and the second sensing part SP2 includes the conductive pattern CTP, capacitance formed by the first sensing part SP1 and the second sensing part SP2 may be increased. Therefore, the touch sensitivity of the input sensing part ISP may be improved.

Portions of some of the grid lines MSL may be cut off to form cut-off areas CA, CA1, and CA2 in each of the first sensing portion SP1 and the second sensing portion SP2. The "cut" state may be a state in which a specific portion of each of some of the grid lines MSL is removed.

For example, the first grid line MSL1 may be cut to form an open space overlapping the k-th second light emitting element OLED2_k in the first direction DR1. The number of the cut first grid lines MSL1 may be set differently. For example, at least one of the first grid lines MSL1 may be cut. A portion of the first grid line MSL1 may be cut to form a cutoff area CA. For example, the cutoff area CA may overlap the second light emitting element OLED2 in the first direction DR1.

The dummy pattern DMP may be spaced apart from the connection pattern CP. The dummy pattern DMP may have substantially the same shape as the first sensing part SP1 and the second sensing part SP2. For example, the dummy pattern DMP may include a dummy grid line DMSL and a dummy conductive pattern DCTP to have a grid shape.
[0236] Therefore, as referenced Fig.13A As described, the dummy grid line DMSL may be disposed between the first light emitting element OLED1 and the second light emitting element OLED2, between the first light emitting element OLED1 and the third light emitting element OLED3, and between the second light emitting element OLED2 and the third light emitting element OLED3.

When viewed in a plan view, the dummy pattern DMP may be disposed below the first and second sensing parts SP1 and SP2 and overlap the first and second sensing parts SP1 and SP2, respectively.
[0238] A ground voltage may be applied to the dummy pattern DMP. However, the present disclosure is not limited thereto, and the dummy pattern DMP may be connected to the first sensing part SP1 and the second sensing part SP2 through a contact hole. In addition, the present disclosure is not limited thereto, and the dummy pattern DMP may be in a floating state while being separated from the peripheral conductive pattern.

For example, the dummy pattern DMP disposed on the lower layer may be connected in the first direction DR1 to serve as a transmission electrode, and the first sensing part SP1 disposed on the upper layer may be connected in the first direction DR1 to serve as a receiving electrode.
[0240] Fig. 27 It is along Fig.26 A cross-sectional view taken along line II-II' is shown.

The first touch insulating layer T-INS1 may be disposed on the base layer BSL, the dummy grid lines DMSL, and the dummy conductive patterns DCTP.
[0243] The grid line MSL and the conductive pattern CTP of the first sensing part SP1 may be disposed on the first touch insulating layer T-INS1. The grid line MSL of the first sensing part SP1 may overlap with the dummy grid line DMSL, and the conductive pattern CTP of the first sensing part SP1 may overlap with the dummy conductive pattern DCTP. The width of the dummy grid line DMSL may be smaller than the width of the grid line MSL. The width of the dummy conductive pattern DCTP may be smaller than the width of the conductive pattern CTP. Fig. 27 In the figure, the “width” may be a value measured in a horizontal direction.

[0246] When the user USR views the conductive pattern CTP and the dummy conductive pattern DCTP from a side, the dummy conductive pattern DCTP may not be seen by the user USR because the width of the dummy conductive pattern DCTP is smaller than the width of the conductive pattern CTP.
[0247] refer to Fig.28B , the conductive pattern CTP and the dummy conductive pattern DCTP may have the same width. In this case, when the user USR views the conductive pattern CTP and the dummy conductive pattern DCTP from the side, the dummy conductive pattern DCTP disposed under the conductive pattern CTP may be seen by the user USR.
[0248] According to an embodiment of the present disclosure, since the width of the dummy conductive pattern DCTP is smaller than the width of the conductive pattern CTP, the dummy conductive pattern DCTP may not be seen by the user USR. For example, although the dummy conductive pattern DCTP and the conductive pattern CTP have been described, the width of the dummy grid line DMSL may also be smaller than the width of the grid line MSL, and therefore, the dummy grid line DMSL may not be seen by the user USR.
[0249] In addition, the mesh line MSL and the conductive pattern CTP of the connection pattern CP disposed in the same layer as the dummy conductive pattern DCTP and the dummy mesh line DMSL may have a smaller width than those of each of the first and second sensing parts SP1 and SP2 .

The area of the conductive pattern can be enlarged between the third light-emitting elements that are spaced farther apart from each other. Therefore, the capacitance formed between the sensing portions can be increased, thereby enhancing the touch sensitivity of the input sensing portion.
[0251] While the present disclosure has been described with reference to the embodiments thereof, it will be apparent to one of ordinary skill 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.
