The surrounding area SA may be a non-display area where no pixels are arranged. The first display area DA1 may be completely or partially surrounded by the surrounding area SA.

[0069] Despite Figure 1 The second display area DA2 is shown as being substantially quadrilateral, but the embodiment is not limited thereto. In a plan view (when viewed in a direction perpendicular to one surface of the substrate), the shape of each second display area DA2 may be variously modified, such as circular, elliptical, polygonal including a quadrilateral, star-shaped, and prism-shaped.

[0070] In addition, despite Figure 1, the second display area DA2 is shown to be arranged on one side (upper right side) of the first display area DA1 having a quadrilateral shape, but the embodiment is not limited thereto. According to some example embodiments, the second display area DA2 may be arranged on one side (e.g., upper left side or upper center) of the first display area DA1 having a quadrilateral shape.

[0071] In addition, despite the Figure 1 , the second display area DA2 is shown to be completely surrounded by the first display area DA1, but the embodiment is not limited thereto. According to some example embodiments, the second display area DA2 may be partially surrounded by the first display area DA1, and a side of the second display area DA2 not surrounded by the first display area DA1 may be surrounded by the surrounding area SA.

[0072] Hereinafter, although the display device 1 according to some example embodiments is described as including an organic light-emitting display panel as an example, the display device 1 according to some example embodiments is not limited thereto. For example, according to some example embodiments, the display device 1 may include various other types of display devices or light-emitting components, such as an inorganic light-emitting display panel and a quantum dot light-emitting display panel. For example, the emission layer of the display element provided to the display panel 10 may include an organic material, an inorganic material, a quantum dot, an organic material and a quantum dot, or an inorganic material and a quantum dot.

[0073] The display device 1 can provide a specific image by using light emitted from a plurality of pixels PX arranged in the first display area DA1 and the second display area DA2. A first pixel array in which the first pixels PX1 are two-dimensionally arranged can be located in the first display area DA1, and a second pixel array in which the second pixels PX2 are two-dimensionally arranged can be located in the second display area DA2.

According to some example embodiments, the resolution of the second image provided in the second display area DA2 may be smaller than the resolution of the first image provided in the first display area DA1.

[0075] The display device 1 may include electronic components in the second display area DA2, and the second display area DA2 may include a transmissive area TA for driving of the electronic components.

[0076] Figure 2 is a schematic cross-sectional view of a portion of a display device 1 according to some example embodiments.

[0077] Reference Figure 2 , the display device 1 may include a display panel 10 and an electronic component 20 overlapping the display panel 10 .

[0078] The display panel 10 may include a substrate 100 , a display layer 200 on the substrate 100 , a thin film encapsulation layer 300 on the display layer 200 , a touch sensing layer 40 , an optical function layer 50 , and a light blocking layer BML.

[0079] The substrate 100 may include glass or a polymer resin. The polymer resin may include polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, and cellulose acetate propionate. The substrate 100 including the polymer resin may be flexible, rollable, or bendable. The substrate 100 may have a multilayer structure including a layer including a polymer resin and an inorganic layer.

[0080] The display layer 200 may be arranged on a first surface (e.g., top surface) of the substrate 100, and the bottom protective film 175 may be arranged on a second surface (e.g., bottom surface) of the substrate 100 opposite to the first surface. The bottom protective film 175 may be attached to the second surface of the substrate 100. An adhesive layer may be arranged between the bottom protective film 175 and the substrate 100. Alternatively, the bottom protective film 175 may be directly formed on the second surface of the substrate 100. In this case, no adhesive layer may be arranged between the bottom protective film 175 and the substrate 100.

[0081] The bottom protective film 175 may support and protect the substrate 100. The bottom protective film 175 may include an opening 175OP corresponding to the second display area DA2. The bottom protective film 175 may increase the transmittance of the second display area DA2, for example, the transmittance of the transmissive area TA, by including the opening 175OP. The bottom protective film 175 may include polyethylene terephthalate (PET) or polyimide (PI).

[0082] The display layer 200 may include a circuit layer, a display element layer, and an insulating layer IL, the circuit layer includes a thin film transistor TFT, and the display element layer includes an organic light emitting diode OLED as a display element. The thin film transistor TFT and the organic light emitting diode OLED electrically connected to the thin film transistor TFT may be arranged in each of the first display area DA1 and the second display area DA2. The second display area DA2 may include a transmission area TA where the thin film transistor TFT and the organic light emitting diode OLED are not arranged.

The touch sensing layer 40 may include sensing electrodes and signal lines connected to the sensing electrodes. The touch sensing layer 40 may sense external input in a mutual capacitance manner or a self-capacitance manner.

[0086] The touch sensing layer 40 may be formed on the thin film encapsulation layer 300. Alternatively, the touch sensing layer 40 may be formed separately and then coupled to the thin film encapsulation layer 300 through an adhesive layer such as an optically clear adhesive (OCA). Figure 2 As shown in FIG. 4 , the touch sensing layer 40 may be directly formed on the thin film encapsulation layer 300 . In this case, the adhesive layer may not be disposed between the touch sensing layer 40 and the thin film encapsulation layer 300 .

[0087] The optical function layer 50 may be formed on the touch sensing layer 40. The optical function layer 50 may include an anti-reflection layer. The anti-reflection layer may reduce reflectivity of light (external light) incident from the outside toward the display panel 10.

[0088] A light blocking layer BML may be disposed between the substrate 100 and the display layer 200. For example, the light blocking layer BML may be disposed between the thin film transistor TFT and the substrate 100.

[0089] The light-blocking layer BML may include an opening BML-OP corresponding to the transmission area TA. The light-blocking layer BML may define the opening BML-OP and include a portion including a light-blocking material (e.g., metal or black ink, etc.) provided to the light-blocking layer BML. The portion of the light-blocking layer BML including the light-blocking material may be arranged to cover the first display area DA1 and a portion of the second display area DA2. The portion of the light-blocking layer BML covering the first display area DA1 and the portion of the light-blocking layer BML covering a portion of the second display area DA2 may be connected to each other as a whole. For example, the light-blocking layer BML may be arranged to correspond to the entire area of ​​the first display area DA1 and the second display area DA2 of the display panel 10 except for the transmission area TA.

[0090] like Figure 2As shown in FIG, the light blocking layer BML may be disposed on the substrate 100. Alternatively, the light blocking layer BML may be disposed in a multi-layer structure of the substrate 100. For example, the light blocking layer BML may be disposed between a plurality of sub-layers constituting the substrate 100. The light blocking layer BML is not an indispensable element and may be omitted according to an embodiment.

[0091] The electronic component 20 may be located in the second display area DA2. The electronic component 20 may include an electronic element that uses light or sound. For example, the electronic element may include a sensor that measures distance (such as a proximity sensor), a sensor that recognizes a part of the user's body (e.g., a fingerprint, an iris, a face, etc.), a small lamp that outputs light, or an image sensor (e.g., a camera) that captures an image. An electronic element that uses light may use light of various wavelength bands including visible light, infrared light, and ultraviolet light. An electronic element that uses sound may use ultrasonic waves or sounds of other frequency bands.

[0092] One electronic component 20 or a plurality of electronic components 20 may be arranged in the second display area DA2. According to some example embodiments, the electronic component 20 may include a light emitter and a light receiver.

[0101] A gate electrode of the emission control thin film transistor T6 is connected to the emission control line EL, one of the source electrode and the drain electrode of the emission control thin film transistor T6 is connected to the driving thin film transistor T1 and the compensation thin film transistor T3, and the other of the source electrode and the drain electrode of the emission control thin film transistor T6 is electrically connected to the second initialization thin film transistor T7 and the pixel electrode of the organic light emitting diode OLED.

[0102] The operation control thin film transistor T5 and the emission control thin film transistor T6 are simultaneously turned on in response to the emission control signal En transmitted through the emission control line EL to allow the driving voltage ELVDD to be transmitted to the organic light emitting diode OLED, and thus the driving current Id flows through the organic light emitting diode OLED.

[0103] The gate electrode of the second initialization thin film transistor T7 may be connected to the third scan line SL+1 of the pixels arranged on the next row of the corresponding pixels PX. In addition, one of the source electrode and the drain electrode of the second initialization thin film transistor T7 is connected to the pixel electrode of the emission control thin film transistor T6 and the organic light emitting diode OLED, and the other of the source electrode and the drain electrode of the second initialization thin film transistor T7 is connected to the second initialization voltage line VL2.

[0104] The first scan line SL may be electrically connected to the third scan line SL+1, and thus, the same scan signal Sn may be applied to the third scan line SL+1. Therefore, the second initialization thin film transistor T7 may be turned on in response to the scan signal Sn transmitted through the third scan line SL+1, and may perform an operation of initializing the pixel electrode of the organic light emitting diode OLED.

[0105] In another example, the first initialization thin film transistor T4 and the second initialization thin film transistor T7 may be simultaneously connected to the second scan line SL- 1 .

[0106] One electrode of the storage capacitor Cap is connected to the driving voltage line PL, and an opposite electrode of the organic light emitting diode OLED is connected to the common voltage ELVSS. Therefore, the organic light emitting diode OLED can display an image by receiving the driving current Id from the driving thin film transistor T1 and emitting light.

[0107] Despite Figure 3, the pixel circuit PC includes seven thin film transistors T1, T2, T3, T4, T5, T6 and T7 and one storage capacitor Cap, but the embodiments of the present disclosure are not limited thereto. The number of thin film transistors and the number of storage capacitors may be variously modified according to the design of the pixel circuit PC.

[0108] Figure 4 is a schematic plan view of a touch sensing layer 40 included in the display device 1 according to some example embodiments.

[0109] Reference Figure 4 , the touch sensing layer 40 may include a plurality of electrodes and signal lines. More specifically, the touch sensing layer 40 may include a plurality of electrodes and signal lines, the plurality of electrodes including a first sensing electrode 410, a first connecting electrode 411, a second sensing electrode 420, and a second connecting electrode 421, and the signal lines including first signal lines 415-1, 415-2, 415-3, and 415-4 respectively connected to the first sensing electrode 410 and second signal lines 425-1, 425-2, 425-3, 425-4, and 425-5 respectively connected to the second sensing electrode 420.

[0110] The first sensing electrodes 410 may be arranged in the y direction, and the second sensing electrodes 420 may be arranged in the x direction intersecting the y direction. The first sensing electrodes 410 arranged in the y direction may be connected to each other through the first connection electrodes 411 between the adjacent first sensing electrodes 410, and may form first sensing lines 410C1, 410C2, 410C3, and 410C4. The second sensing electrodes 420 arranged in the x direction may be connected to each other through the second connection electrodes 421 between the adjacent second sensing electrodes 420, and may form second sensing lines 420R1, 420R2, 420R3, 420R4, and 420R5. The first sensing lines 410C1 to 410C4 and the second sensing lines 420R1 to 420R5 may intersect with each other. For example, the first sensing lines 410C1 to 410C4 and the second sensing lines 420R1 to 420R5 may be perpendicular to each other.

[0111] The first sensing lines 410C1 to 410C4 may be connected to the pads of the sensing signal pad unit 440 through the first signal lines 415-1 to 415-4 formed in the surrounding area SA. For example, each of the first signal lines 415-1 to 415-4 may have a dual routing structure in which the first signal lines 415-1 to 415-4 are respectively connected to the upper and lower sides of the first sensing lines 410C1 to 410C4. Each of the first signal lines 415-1 to 415-4 respectively connected to the upper and lower sides of the first sensing lines 410C1 to 410C4 may be connected to corresponding first pads 441C1 and 441C2.

[0112] The second sensing lines 420R1 to 420R5 may be connected to the pads of the sensing signal pad unit 440 through the second signal lines 425-1 to 425-5 formed in the surrounding area SA. For example, each of the second signal lines 425-1 to 425-5 may be connected to the corresponding second pad 442R.

[0113] The ground line may be arranged in the surrounding area SA to prevent damage caused by static electricity introduced into the touch sensing layer 40 from the outside (eg, static electricity introduced into the surrounding area SA). Figure 4 A first ground line 461 extending along the left and upper sides of the surrounding area SA and a second ground line 462 extending along the right side of the surrounding area SA are shown. The first ground line 461 and the second ground line 462 may be spaced apart from each other by a certain interval. Figure 4 4 shows that the first ground line 461 and the second ground line 462 are spaced apart from each other in an area of ​​the surrounding area SA adjacent to the upper right side of the display area DA. The first ground line 461 and the second ground line 462 may be connected to corresponding pads 446a and 446b, respectively. Each of the first ground line 461 and the second ground line 462 may have a voltage level of a constant voltage (e.g., a zero voltage, a negative direct current (DC) voltage, or a positive DC voltage). The first ground line 461 and the second ground line 462 may have constant voltages of different levels or constant voltages of the same level.

[0114] The guard lines may be arranged around the group of first signal lines 415-1 to 415-4 and the group of second signal lines 425-1 to 425-5 to prevent interference between adjacent lines or wirings. Figure 4 As shown in, the first protection line 451 may be located between the first ground line 461 and the group of the upper first signal lines 415-1 to 415-4. The second protection line 452 may be located between the second ground line 462 and the group of the second signal lines 425-1 to 425-5. The third protection line 453 may be located between the group of the upper first signal lines 415-1 to 415-4 and the group of the lower first signal lines 415-1 to 415-4, and the fourth protection line 454 may be located between the group of the lower first signal lines 415-1 to 415-4 and the group of the second signal lines 425-1 to 425-5. The first protection line 451, the second protection line 452, the third protection line 453 and the fourth protection line 454 may be connected to the corresponding pads 445a, 445b, 445c and 445d, respectively. Each of the first protection line 451, the second protection line 452, the third protection line 453, and the fourth protection line 454 may have a voltage level of a constant voltage. For example, the first protection line 451, the second protection line 452, the third protection line 453, and the fourth protection line 454 may have constant voltages of different levels or the same level.

[0115] although Figure 4 A dual routing structure is shown in which the first signal lines 415-1 to 415-4 are respectively connected to the upper and lower sides of the first sensing lines 410C1 to 410C4, but embodiments according to the present disclosure are not limited thereto. According to some example embodiments, the first signal lines 415-1 to 415-4 may be connected only to the upper or lower sides of the first sensing lines 410C1 to 410C4.

[0116] Figure 5 is a schematic cross-sectional view of a stacked structure of a touch sensing layer 40 according to some example embodiments.

[0117] Reference Figure 5 The touch sensing layer 40 may include a first conductive layer 42 and a second conductive layer 44. A first insulating layer 41 may be disposed below the first conductive layer 42, a second insulating layer 43 may be disposed between the first conductive layer 42 and the second conductive layer 44, and a third insulating layer 45 may be disposed on the second conductive layer 44. Figure 4 Each of the described first sensing electrode 410 , the first connection electrode 411 , the second sensing electrode 420 , and the second connection electrode 421 may be included in one of the first conductive layer 42 and the second conductive layer 44 .

[0118] The first conductive layer 42 and the second conductive layer 44 may include a metal layer or a transparent conductive layer. The metal layer may include molybdenum (Mo), mendelevium (Md), silver (Ag), titanium (Ti), copper (Cu), aluminum (Al) or an alloy thereof. The transparent conductive layer may include a transparent conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO) or indium tin zinc oxide (ITZO). In addition, the transparent conductive layer may include a conductive polymer such as poly (3,4-ethylenedioxythiophene) (PEDOT), metal nanowires, graphene, etc.

[0119] Each of the first conductive layer 42 and the second conductive layer 44 may be a single layer or a multilayer. The first conductive layer 42 and the second conductive layer 44, each including a single layer, may include a single metal layer or a single transparent conductive layer, and the materials of the metal layer and the transparent conductive layer are as described above. One of the first conductive layer 42 and the second conductive layer 44 may include a single metal layer. The single metal layer may include a Mo layer or an alloy layer of MoMd.

[0120] One of the first conductive layer 42 and the second conductive layer 44 may include a multilayer metal layer. The multilayer metal layer may include, for example, three layers of a Ti layer / Al layer / Ti layer, or two layers of a Mo layer / Md layer. Alternatively, the multilayer metal layer may include a metal layer and a transparent conductive layer. The first conductive layer 42 and the second conductive layer 44 may have different stacking structures or the same stacking structure. For example, the first conductive layer 42 may include a metal layer, and the second conductive layer 44 may include a transparent conductive layer. Alternatively, the first conductive layer 42 and the second conductive layer 44 may include the same metal layer.

[0121] The materials of the first conductive layer 42 and the second conductive layer 44 and the sensing electrodes ( Figure 4 The arrangement of 410 and 420) may be determined in consideration of sensing sensitivity. Resistance capacitance (RC) delay may affect sensing sensitivity, and the resistance of each sensing electrode including the metal layer is less than the resistance of the transparent conductive layer, thereby reducing the RC value. Therefore, the charging time of the capacitor defined between the sensing electrodes may be shortened. Compared with the metal layer, the sensing electrode including the transparent conductive layer may be invisible to the user, and the input area may be increased to increase the capacitance.

[0122] Each of the first insulating layer 41, the second insulating layer 43, and the third insulating layer 45 may include an inorganic insulating material and / or an organic insulating material. The inorganic insulating material may include silicon oxide, silicon nitride, or silicon oxynitride, and the organic insulating material may include a polymer organic material.

[0123] Reference Figure 4 Some of the described first and second sensing electrodes 410 and 420 and the first and second connection electrodes 411 and 421 may be disposed on the first conductive layer 42 , while others may be disposed on the second conductive layer 44 .

[0124] According to some example embodiments, the first conductive layer 42 may include a first connection electrode 411 (see Figure 4 ), and the second conductive layer 44 may include a first sensing electrode 410 and a second sensing electrode 420 (see Figure 4 ) and the second connecting electrode 421 (see Figure 4). According to some example embodiments, the first conductive layer 42 may include the first sensing electrode 410 and the second sensing electrode 420 and the second connection electrode 421, and the second conductive layer 44 may include the first connection electrode 411. According to some example embodiments, the first conductive layer 42 may include the first sensing electrode 410 and the first connection electrode 411, and the second conductive layer 44 may include the second sensing electrode 420 and the second connection electrode 421. In this case, the first sensing electrode 410 and the first connection electrode 411 may be disposed on the same layer to be integrally connected to each other, and the second sensing electrode 420 and the second connection electrode 421 may also be disposed on the same layer, and therefore, a contact hole may not be disposed in the insulating layer between the first conductive layer 42 and the second conductive layer 44.

[0125] Despite Figure 5 , the touch sensing layer 40 includes a first insulating layer 41, a first conductive layer 42, a second insulating layer 43, a second conductive layer 44, and a third insulating layer 45, but according to some example embodiments, the first insulating layer 41 under the first conductive layer 42 may be omitted.

[0126] Figure 6 is a schematic plan view of a first conductive layer 42 of a touch sensing layer 40 included in a display device 1 according to some example embodiments, and Figure 7 is a schematic plan view of a second conductive layer 44 of a touch sensing layer 40 included in the display device 1 according to some example embodiments. Figure 6 and Figure 7 The first conductive layer 42 and the second conductive layer 44 in the first display area DA1 of the touch sensing layer 40 are respectively shown.

[0127] Each of the first sensing electrode 410 and the second sensing electrode 420 and the first connection electrode 411 and the second connection electrode 421 may have a mesh (or grid) pattern. When the first sensing electrode 410 and the second sensing electrode 420 include a metal layer, the first sensing electrode 410 and the second sensing electrode 420 may have a mesh (or grid) pattern. Figure 6 and Figure 7 , so as to prevent first sensing electrode 410 and second sensing electrode 420 from being visible to a user and / or so as to transmit light emitted from each pixel.

[0128] Reference Figure 6 , the first conductive layer 42 of the touch sensing layer 40 may include a first connection electrode 411. The first connection electrode 411 may include a first conductive line CL1 having a mesh pattern, and may include an opening 411OP surrounded by the first conductive line CL1. The opening 411OP may be arranged to overlap with the first pixel PX1 of the display panel 10.

[0129] The first connection electrodes 411 may electrically connect the first sensing electrodes 410 to each other, and the first sensing electrodes 410 are formed on a layer different from the first connection electrodes 411. The first connection electrodes 411 electrically connecting adjacent first sensing electrodes 410 may be formed on the second insulating layer 43 (see Figure 5 ) is connected to the first sensing electrode 410.

[0130] Reference Figure 7 , the second conductive layer 44 of the touch sensing layer 40 may include a first sensing electrode 410, a second sensing electrode 420, and a second connection electrode 421. The first sensing electrode 410, the second sensing electrode 420, and the second connection electrode 421 may include a first conductive line CL1 having a mesh pattern, and may include openings 410OP, 420OP, and 421OP surrounded by the first conductive line CL1, respectively. The openings 410OP, 420OP, and 421OP may be arranged to overlap with the first pixel PX1 of the display panel 10.

[0131] The second sensing electrodes 420 may be connected to each other through a second connection electrode 421 formed on the same layer as the second sensing electrodes 420. For example, the second sensing electrode 420 may include the same material as the second connection electrode 421 and may be integrally formed therewith.

[0132] The first sensing electrodes 410 may be electrically connected to each other through the first connection electrodes 411 formed on a layer different from the first sensing electrodes 410. The first sensing electrodes 410 may be electrically connected to each other through the first connection electrodes 411 formed on the second insulating layer 43 (see Figure 5 ) is connected to the first sensing electrode 410.

[0133] Figure 8 is a schematic enlarged plan view of a display device 1 according to some example embodiments. Figure 8 The second display area DA2 of the display device 1 and the touch sensing layer 40 disposed in a portion of the first display area DA1 adjacent to the second display area DA2 are shown.

[0134] Reference Figure 8 A first pixel array in which a plurality of first pixels PX1 are two-dimensionally arranged in an x ​​direction and a y direction different from the x direction may be located in the first display area DA1. A second pixel array in which a plurality of second pixels PX2 are two-dimensionally arranged in the x direction and the y direction and are spaced apart from each other with a transmission area therebetween may be located in the second display area DA2.

[0135] The number of first pixels PX1 per same area in the first display area DA1 may be greater than the number of second pixels PX2 per same area in the second display area DA2. Accordingly, the resolution of the first image provided in the first display area DA1 may be higher than the resolution of the second image provided in the second display area DA2.

[0136] As reference Figure 6 and Figure 7 As described, a plurality of electrodes including the first and second conductive lines CL1 and CL2 having a mesh pattern may be arranged on the display panel 10 including the plurality of pixels PX.

[0137] At least one of the first sensing electrode 410, the second sensing electrode 420, the first connection electrode 411, and the second connection electrode 421 may at least partially overlap with the second display area DA2. Figure 8 It is shown that the first sensing electrode 410, the second sensing electrode 420, the first connection electrode 411, and the second connection electrode 421 at least partially overlap with the second display area DA2.

[0138] Reference Figure 8 The first sensing electrodes 410 arranged in the y direction and the second sensing electrodes 420 arranged in the x direction may be arranged across the boundary between the first display area DA1 and the second display area DA2. In addition, the first connection electrode 411 and the second connection electrode 421 may be arranged in the second display area DA2.

[0139] As a comparative example, the plurality of electrodes may not be arranged in the second display area DA2. In this case, coordinate information according to an external input (e.g., a touch event) may not be obtained in the second display area DA2. In addition, the sensing sensitivity may be degraded in an area of ​​the first display area DA1 adjacent to the second display area DA2.

[0140] However, according to some example embodiments, since a plurality of electrodes are arranged in the second display area DA2 in addition to the first display area DA1, coordinate information according to a touch event can be obtained in the second display area DA2. In addition, degradation of sensing sensitivity that may occur in an area of ​​the first display area DA1 adjacent to the second display area DA2 can be prevented or minimized.

[0141] The second display area DA2 may be provided with a pixel circuit PC (see FIG. Figure 3 ) wiring WL.

[0142] In the following, reference will be made to Fig. 9 and Fig.10The arrangement of pixels, transmissive regions, wiring regions, and touch sensing layers is described in more detail.

[0143] Fig. 9 is a schematic enlarged plan view of a display panel 10 according to some example embodiments, illustrating an arrangement of pixels, a transmission region, a wiring region, and a touch sensing layer included in the display panel 10 . Fig. 9 Corresponds to Figure 8 of Zone IX.

[0144] Reference Fig. 9 , the plurality of second pixels PX2 arranged in the second display area DA2 may be grouped in preset units to form a pixel group PG. Fig. 9 In the embodiment, eight second pixels PX2 are defined to constitute one pixel group PG, but the embodiment of the present disclosure is not limited thereto. The number of second pixels PX2 constituting one pixel group PG may be modified according to the resolution of the second display area DA2.

[0145] Reference Fig. 9 , the pixel group PG formed by the plurality of second pixels PX2 may include a first group PX21 of second pixels and a second group PX22 of second pixels, and the first group PX21 of second pixels and the second group PX22 of second pixels may be spaced apart from each other with the transmission area TA therebetween. The first group PX21 of second pixels and the second group PX22 of second pixels may be arranged two-dimensionally in the x-direction and the y-direction. The pixel group PG and the transmission area TA are repeatedly arranged, and thus, a second pixel array may be formed.

[0146] The second display area DA2 may be provided with pixel circuits PC electrically connected to the second pixels PX2 respectively (see Figure 3 ) of a plurality of wirings WL. The wirings WL include at least one first wiring WL1 and at least one second wiring WL2 extending in directions intersecting each other. The first wiring WL1 may include a data line DL (see Figure 3 ) or the driving voltage line PL (see Figure 3 ), and the second wiring WL2 may include scan lines SL-1, SL, and SL+1 (see Figure 3 ).

[0147] The first wiring WL1 may be entirely arranged to extend in the y direction to connect pixel circuits PC respectively corresponding to the second pixels PX2 arranged in the same column. The second wiring WL2 may be entirely arranged to extend in the x direction to connect pixel circuits PC respectively corresponding to the second pixels PX2 arranged in the same row. The x direction and the y direction may be orthogonal to each other, or may be different directions that are not orthogonal to each other.

[0148] The transmission area TA may be defined as an area of ​​the second display area DA2 excluding a pixel area PA where the second pixel PX2 and a pixel circuit PC corresponding to the second pixel PX2 are located and a wiring area WA where the wiring WL is located.

[0149] The wiring area WA may include a first wiring area WA1 and a second wiring area WA2, the first wiring area WA1 may include an area where at least one first wiring WL1 is located and an area between adjacent first wirings WL1, and the second wiring area WA2 may include an area where at least one second wiring WL2 is located and an area between adjacent second wirings WL2. Fig. 9 The pixel area PA is indicated by a dotted line, and the wiring area WA is indicated by a double-dashed line. The shape of the transmission area TA may be variously formed according to the arrangement and shape of the second pixel PX2 and the wiring WL, such as a polygon including a quadrilateral, a circle, an ellipse, and a diamond.

[0150] Reference Fig. 9 , touch sensing layer 40 (see Figure 4 ) may be arranged on the display panel 10, and the touch sensing layer 40 (see Figure 4 ) may include a plurality of electrodes, namely, a first sensing electrode 410 (see Figure 4 ), the second sensing electrode 420 (see Figure 4 ), the first connection electrode 411 (see Figure 4 ) and the second connecting electrode 421 (see Figure 4 ).

[0151] The electrode may include a first conductive line CL1 disposed on the first display area DA1 and a second conductive line CL2 disposed on the second display area DA2. The first conductive line CL1 and the second conductive line CL2 may include the same material and may be formed integrally with each other.

[0152] The first conductive line CL1 may include a mesh pattern having a plurality of first openings CL1-OP respectively corresponding to at least one first pixel PX1 of the first pixels PX1 arranged on the first display area DA1. The second conductive line CL2 may include a mesh pattern having a plurality of second openings CL2-OP respectively corresponding to at least one second pixel PX2 of the second pixels PX2 arranged on the second display area DA2. At least one conductive line CL2-C of the second conductive line CL2 may extend in the y direction or in the x direction intersecting the y direction between adjacent pixel groups PG. The first conductive line CL1 and the second conductive line CL2 may include a mesh pattern so as to prevent the first conductive line CL1 and the second conductive line CL2 from being visible to a user when the first conductive line CL1 and the second conductive line CL2 include metal, and / or so as to transmit light emitted from each pixel PX.

[0153] The first conductive line CL1 may be arranged between two adjacent first pixels PX1 among the first pixels PX1, and the second conductive line CL2 may be arranged between two adjacent second pixels PX2 among the second pixels PX2. The second conductive line CL2 may include a first group CL21 of second conductive lines arranged between at least two second pixels PX2 among the first group PX21 of second pixels and a second group CL22 of second conductive lines arranged between at least two second pixels PX2 among the second group PX22 of second pixels.

[0154] For example, refer to Fig. 9 , at least one of the second conductive lines CL2-C may extend in the x direction from the first group CL21 of second conductive lines to connect to the second group CL22 of second conductive lines adjacent to the first group CL21 of second conductive lines. In addition, at least one of the second conductive lines CL2-C may extend in the y direction from the first group CL21 of second conductive lines to connect to the second group CL22 of second conductive lines adjacent to the first group CL21 of second conductive lines. That is, at least one of the second conductive lines CL2-C may extend between the first group CL21 of second conductive lines and the second group CL22 of second conductive lines to connect the first group CL21 of second conductive lines to the second group CL22 of second conductive lines.

[0155] At least one conductive line CL2 -C of the second conductive lines CL2 may be integrally formed with the first group CL21 of second conductive lines and / or the second group CL22 of second conductive lines, and may include the same material as each other.

[0156] In order to minimize the reduction in the area of ​​the transmission area TA, the second conductive line CL2 may be arranged to overlap the pixel area PA and the wiring area WA. That is, the first group CL21 of the second conductive line may overlap the area where the first group PX21 of the second pixel is located, and the second group CL22 of the second conductive line may overlap the area where the second group PX22 of the second pixel is located. In addition, at least one conductive line CL2-C of the second conductive line CL2 that connects the first group PX21 of the second pixel to the second group PX22 of the second pixel may be arranged adjacent to the first wiring WL1 or the second wiring WL2, and therefore, at least a portion of at least one conductive line CL2-C may overlap the first wiring WL1 or the second wiring WL2. At least one conductive line CL2-C of the second conductive line CL2 may overlap the first wiring area WA1 or the second wiring area WA2.

[0157] Reference Fig. 9 , the width WD2 of the second conductive line CL2 may be greater than the width WD1 of the first conductive line CL1. RC delay may affect sensing sensitivity, and when the width of the conductive line CL included in the plurality of electrodes increases, the input area also increases, which may increase the capacitance of the conductive line CL, thereby improving sensing sensitivity.

[0158] Since the second display area DA2 includes the transmissive area TA where the second conductive line CL2 is not arranged, unlike the first display area DA1, the area of ​​the conductive line CL arranged per the same area in the second display area DA2 may be smaller than the area of ​​the conductive line CL arranged per the same area in the first display area DA1. Therefore, the sensing sensitivity in the second display area DA2 may be lower than the sensing sensitivity in the first display area DA1. In order to solve this problem, the width WD2 of the second conductive line CL2 arranged in the second display area DA2 may be formed to be larger than the width WD1 of the first conductive line CL1 arranged in the first display area DA1, and thus, the sensing sensitivity in the second display area DA2 may be improved.

[0159] Fig.10 is a schematic enlarged plan view of a display device 1 according to some example embodiments, illustrating an arrangement of pixels, a transmission region, a wiring region, and a touch sensing layer included in a display panel 10 . Fig.10 Corresponds to Figure 8 The arrangement of the second pixel PX2, the transmission area TA and the wiring WL in the second display area DA2 is similar to the arrangement of the second pixel PX2, the transmission area TA and the wiring WL in the second display area DA2. Fig. 9 The arrangements described are the same, and the following will mainly describe the differences between them.

[0160] Reference Fig.10 , the pixel group PG formed by the plurality of second pixels PX2 may include a first group PX21 of second pixels arranged in the x direction and a second group PX22 of second pixels. In addition, the pixel group PG may include a third group PX23 of second pixels and a fourth group PX24 of second pixels arranged in the y direction different from the x direction.

[0161] For example, in Fig.10 , the first group PX21 of the second pixels is arranged between the third group PX23 of the second pixels and the fourth group PX24 of the second pixels. The second group PX22 of the second pixels may be arranged adjacent to the first group PX21 of the second pixels in the x direction. The second group PX22 of the second pixels may be arranged between the third group PX23 of the second pixels and the fourth group PX24 of the second pixels. In this case, the first group PX21 of the second pixels may be arranged adjacent to the second group PX22 of the second pixels in the x direction.

[0162] The second conductive line CL2 may include a third group CL23 of second conductive lines located between at least two second pixels PX2 in the third group PX23 of second pixels.

[0200] Fig.12is a schematic cross-sectional view of a display device according to some example embodiments, illustrating the arrangement of a first conductive layer 42 and a second conductive layer 44 of a touch sensing layer 40 . Fig.12 It may correspond to a cross section of the display device taken along line BB′, a cross section of the display device taken along line CC′, and a cross section of the display device taken along line DD′.

[0201] Since the stacking structure of the display panel 10 and the touch sensing layer 40 is similar to the reference Fig.11 The stacking structures described are the same, so the following will mainly describe the differences between them, and some repeated descriptions of certain components may be omitted.

Referring to Fig.12 In the touch sensing layer 40 in the cross section of the display device taken along the line BB' in FIG. 1 , the second conductive layer 44 including the second conductive wire CL2 may be arranged on the second insulating layer 43. The second conductive wire CL2 may overlap the pixel defining layer 119 covering the edge of the pixel electrode 210 located in the second display area DA2. Since the second conductive wire CL2 is not arranged on the transmission area TA, even if the second conductive wire CL2 includes a metal layer, degradation of the transmittance in the transmission area TA may be prevented. In addition, the second conductive wire CL2 does not overlap with the second pixel PX2, and therefore, blocking of light emitted from the emission area of ​​the organic light emitting diode OLED may be prevented or minimized.

[0203] The pixel circuit PC, the pixel electrode 210, and the second conductive line CL2 may not overlap with the opening BML-OP of the light blocking layer BML, and may be located in a region where the light blocking layer BML is disposed.

[0205] At least one of the second conductive lines CL2-C may be disposed on the second insulating layer 43. In addition, at least one of the second conductive lines CL2-C may be disposed to overlap the second wiring area WA2. Accordingly, since at least one of the second conductive lines CL2-C is not disposed on the transmission area TA, deterioration of transmittance in the transmission area TA may be prevented.

[0206] Reference Fig.12 In the cross section of the display device taken along line DD' in FIG. 1 , the first wiring WL1 may be arranged on the second interlayer insulating layer 115. The region where the first wiring WL1 is arranged and the region between adjacent first wirings WL1 may be defined as a first wiring region WA1. The first wiring WL1 may include a data line DL (see Figure 3 ) or the driving voltage line PL (see Figure 3 ).

[0207] The connection wire CCL may be disposed on the first insulating layer 41. Also, the connection wire CCL may be disposed to overlap the first wiring area WA1. Accordingly, since the connection wire CCL is not disposed on the transmission area TA, deterioration of transmittance in the transmission area TA may be prevented.

[0208] The light blocking layer BML may be disposed on the substrate 100 to correspond to the first and second wiring areas WA1 and WA2 . The light blocking layer BML may prevent light incident on the display panel 10 from being diffracted while passing through a narrow gap between the wirings WL and accidentally incident on the electronic component 20 .
