[0109] Optional, such as Figure 5As shown, the first touch electrode 410 is located between the adjacent isolation opening 310 and the first light-transmitting opening 320. On a plane perpendicular to the substrate 100, on a cross section passing through the center of the adjacent first light-transmitting opening 320 and the center of the isolation opening 310, the minimum spacing from the first touch electrode 410 to the side wall of the isolation structure 300 facing the isolation opening 310 is equal to the minimum spacing from the first touch electrode 410 to the side wall of the isolation structure 300 facing the first light-transmitting opening 320.

[0112] In these optional embodiments, the first spacing A is equal to the second spacing a, so that the first touch electrode 410 and the second touch electrode 420 have the same influence on the light emission of the light-emitting unit 200 .

[0113] Optional, such as Figure 6As shown, on a plane perpendicular to the substrate 100, on a cross section passing through the center of the adjacent isolation opening 310, the spacing between the second touch electrode 420 facing the same isolation opening 310 and the isolation structure 300 is a third spacing f, and on a plane perpendicular to the substrate 100, on a cross section passing through the center of the adjacent isolation opening 310 and the center of the first light-transmitting opening 320, there is a fourth spacing F between the first touch electrode 410 facing the first light-transmitting opening 320 and the isolation structure 300, and the third spacing f is smaller than the fourth spacing F. Since the width of the first touch electrode 410 is smaller than the width of the second touch electrode 420, when the first spacing A is equal to the second spacing a, the third spacing f between the second touch electrode 420 facing the same isolation opening 310 and the isolation structure 300 is smaller than the fourth spacing F between the first touch electrode 410 facing the first light-transmitting opening 320 and the isolation structure 300, thereby reducing the influence of the first touch electrode 410 on the transmittance of the first light-transmitting opening 320.

When the width of the first touch electrode 410 is 2 micrometers to 2.5 micrometers, the width E of the third touch electrode 430 is smaller than the width of the first touch electrode 410, which increases the risk of disconnection of the third touch electrode 430.

Since the display device provided by the embodiment of the second aspect of the present application includes the display panel of any of the above-mentioned embodiments of the first aspect, the display device provided by the embodiment of the second aspect of the present application has the beneficial effects of the display panel of any of the above-mentioned embodiments of the first aspect, which will not be repeated here.

Fig.10 As shown, the manufacturing method comprises the following steps:

[0148] Step S01: Fig.11 As shown, an isolation structure 300 is formed on one side of the substrate 100 , and the isolation structure 300 encloses an isolation opening 310 .

[0149] Step S02: Fig.12 As shown, a light emitting layer is formed on one side of the substrate 100 , and the light emitting layer includes a light emitting unit 200 located in the isolation opening 310 .

[0150] Step S03: Fig.13 As shown, a touch material layer 401 is formed on the side of the isolation structure 300 facing away from the substrate 100 .

[0151] Step S04: Figure 3As shown, the patterned touch material layer 401 forms a first touch electrode 410 at least partially located in the first display area A1 and a second touch electrode 420 located in the second display area A2; wherein, at least a portion of the first touch electrode 410 has a width along a direction perpendicular to the thickness of the substrate 100 that is smaller than the width of the second touch electrode 420 along a direction perpendicular to the thickness of the substrate 100.

[0152] In this embodiment, the isolation structure 300 encloses a plurality of isolation openings 310, and the light-emitting units 200 are disposed in each isolation opening 310. The isolation structure 300 can reduce light crosstalk between different light-emitting units 200. The width of the first touch electrode 410 along the direction perpendicular to the thickness of the substrate 100 is smaller than the width of the second touch electrode 420 along the direction perpendicular to the thickness of the substrate 100, thereby increasing the light transmittance of the first display area A1, thereby improving the process performance of the display panel.

[0153] In some optional embodiments, the second display area A2 includes the middle area 10 and the edge area 20 disposed on at least one side of the middle area 10. In step S04, Fig.14 As shown, including:

[0154] Step S041: Fig.15 As shown, a photoresist layer 800 is formed on the touch material layer 401 .

[0155] Step S042: Fig.16 and Fig.17 As shown, a mask plate 900 is used to expose the photoresist layer 800 to form a first photoresist pattern 810 in the first display area A1, a second photoresist pattern 820 located in the middle area 10, and a third photoresist pattern 830 located in the edge area 20. The width of the first photoresist pattern 810 along the direction perpendicular to the thickness of the substrate 100 is smaller than the width of the second photoresist pattern 820 along the direction perpendicular to the thickness of the substrate 100, and the width of the third photoresist pattern 830 along the direction perpendicular to the thickness of the substrate 100 is equal to the width of the first photoresist pattern 810 along the direction perpendicular to the thickness of the substrate 100.

[0156] Step S043: Fig.18 As shown, the touch material layer 401 outside the area covered by the first photoresist pattern 810, the second photoresist pattern 820 and the third photoresist pattern 830 is etched to form a first touch electrode 410, a second touch electrode 420 and a third touch electrode 430, and the width of the first touch electrode 410 along the direction perpendicular to the thickness of the substrate 100 is equal to the width of the third touch electrode 430 along the direction perpendicular to the thickness of the substrate 100.

[0157] In these optional embodiments, when forming the touch layer 400 , the distance between the edge area 20 and the exposure light source is smaller than the distance between the first display area A1 and the middle area 10 and the exposure light source, thereby increasing the exposure intensity of the photoresist layer 800 in the edge area 20 . The width M of the mask opening 910 at the position of the mask plate 900 corresponding to the first photoresist pattern 810 is smaller than the width N of the mask opening 910 at the position of the mask plate 900 corresponding to the second photoresist pattern 820, the width M of the mask opening 910 at the position of the mask plate 900 corresponding to the first photoresist pattern 810 is smaller than the width P of the mask opening 910 at the position of the mask plate 900 corresponding to the third photoresist pattern 830, and the width of the mask opening 910 at the position of the mask plate 900 corresponding to the first photoresist pattern 810 is set to be smaller than the opening width of the mask plate 900 corresponding to the third photoresist pattern 830, so that the width of the third photoresist pattern 830 along the direction perpendicular to the thickness of the substrate 100 is equal to the width of the first photoresist pattern 810 along the direction perpendicular to the thickness of the substrate 100. The touch material layer 401 outside the area covered by the first photoresist pattern 810, the second photoresist pattern 820 and the third photoresist pattern 830 is etched to form the first touch electrode 410, the second touch electrode 420 and the third touch electrode 430. The width of the first touch electrode 410 along the direction perpendicular to the thickness of the substrate 100 is equal to the width of the third touch electrode 430 along the direction perpendicular to the thickness of the substrate 100, thereby reducing the risk of disconnection of the third touch electrode 430.

[0161] In these optional embodiments, the planarization layer 700 is used to planarize the first display area A1, the middle area 10 and the edge area 20, thereby reducing the height difference between the first display area A1, the edge area 20 and the middle area 10, and avoiding the risk of overexposure and line breakage due to the third touch electrode 430 being closer to the exposure light source when forming the third touch electrode 430 in the edge area 20.

[0162] In some optional embodiments, in step S04, it further includes:

[0163] A photoresist layer 800 is formed on the touch material layer 401 .

[0165] The touch material layer 401 outside the area covered by the first photoresist pattern 810 , the second photoresist pattern 820 and the third photoresist pattern 830 is etched to form the first touch electrode 410 , the second touch electrode 420 and the third touch electrode 430 .

[0166] In these optional embodiments, the planarization layer 700 is used to planarize the first display area A1, the middle area 10, and the edge area 20, so that in the process of using the mask plate 900 to expose the photoresist layer 800 to form the first photoresist pattern 810 and the second photoresist pattern 820 located in the middle area 10 and the third photoresist pattern 830 located in the edge area 20, the first photoresist pattern 810, the second photoresist pattern 820, and the third photoresist pattern 830 are at the same distance from the exposure light source, thereby reducing the risk of the third photoresist pattern 830 being overexposed. The width of the mask opening 910 at the position is equal to the width of the mask opening 910 at the position of the second photoresist pattern 820 on the mask plate 900 and is equal to the width of the mask opening 910 at the position of the third photoresist pattern 830 on the mask plate 900, so that the width of the first photoresist pattern 810 along the direction perpendicular to the thickness of the substrate 100 is equal to the width of the second photoresist pattern 820 along the direction perpendicular to the thickness of the substrate 100 and is equal to the width of the third photoresist pattern 830 along the direction perpendicular to the thickness of the substrate 100, so that the widths of the first touch electrode 410, the second touch electrode 420 and the third touch electrode 430 are equal.
