Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] OLED (Organic Light-Emitting Diode) display devices are widely used due to their advantages such as self-luminescence, wide color gamut, low power consumption, and flexible display. In order to reduce the thickness of existing OLED display devices, DOT (Direct On Cell Touch, the touch layer is directly made on the display panel) technology is used to prepare the touch layer. In order to solve the problem that the polarizer is thick and the outgoing light of the OLED display device is absorbed, resulting in low light efficiency and high power consumption, a depolarizer (Pol Less Panel, PLP) technology is proposed. By replacing the polarizer with a black matrix and a color resistor, the external reflected light is reduced while the light transmittance of the OLED display device is improved. It can be seen that in the preparation process of the OLED display device, the touch layer, the black matrix and the color resistor need to be prepared, resulting in a large number of mask plates required, a more complicated preparation process, and a lower preparation efficiency of the display device.

[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0034] In order to explain the principle of the technical problem in the embodiment of the present application, the embodiment of the present application provides a comparative display device. It is understandable that the comparative display device cannot be used as the prior art in the embodiment of the present application. Figure 1As shown, the comparative display device includes a light-emitting film, a packaging film 12, a touch film, a filter film, a black matrix film 14 and a flat film 16, the light-emitting film includes a red light-emitting device 111, a blue light-emitting device 112 and a green light-emitting device 113, the touch film includes a first metal film 131, a first insulating film 132, a second metal film 133 and a second insulating film 134, the filter film includes a red light color resist 151, a blue light color resist 152 and a green light color resist 153, when the comparative display device displays, the light emitted by each light-emitting device will be emitted from the gap between the first metal film 131 and the second metal film 133 and then emitted to the corresponding filter color resist, and then emitted from the comparative display device, Figure 1 It can be seen that the first metal film, the first insulating film, the second metal film, the second insulating film, the black matrix film, the red light color resist, the blue light color resist and the green light color resist need to be prepared separately on the encapsulation layer, resulting in a larger number of mask plates required for the comparative display device, higher cost, more complicated preparation process and lower preparation efficiency of the display device. Therefore, the existing OLED display device has the technical problem of low preparation efficiency due to the need to prepare the touch layer, black matrix and color resist separately.

[0035] In view of the above technical problems, the embodiments of the present application provide a display panel and a display device to solve the above technical problems.

[0037] like Figure 2 , Figure 3 As shown, an embodiment of the present application provides a display panel, the display panel 2 includes a display area 201, the display area 201 includes a plurality of light-transmitting areas 201a and a plurality of non-light-transmitting areas 201b, the display panel 2 includes a substrate 21, a touch layer 25 and a color filter layer 26, the touch layer 25 is arranged on one side of the substrate 21, the touch layer 25 includes a first touch metal layer 251 and a second touch metal layer 252, the second touch metal layer 252 is arranged on a side of the first touch metal layer 251 away from the substrate 21; the color filter layer 26 is arranged on one side of the substrate 21, the color filter layer 26 at least includes a first color resist 261, and the first color resist 261 is arranged between the first touch metal layer 251 and the second touch metal layer 252;

[0038] The first color resist 261 is disposed in the non-light-transmitting area 201 b , and the first color resist 261 is disposed in a portion of the light-transmitting area 201 a .

[0039] The embodiments of the present application provide a display panel and a display device; the display panel arranges a first color resist between the first touch metal layer and the second touch metal layer, and the first color resist is arranged in a non-light-transmitting area, and the first color resist is arranged in a partially light-transmitting area, so that the first color resist can be used as an insulating layer between the first touch metal layer and the second touch metal layer, and at least one process for preparing the insulating layer between the first touch metal layer and the second touch metal layer is reduced, thereby improving the preparation efficiency of the display panel, and the first color resist can be arranged in the partially light-transmitting area for filtering, so as to realize normal display of the display panel.

[0040] In some embodiments, Figure 2 , Figure 3 As shown, the light-transmitting area 201a includes a first light-transmitting area 301, a second light-transmitting area 302 and a third light-transmitting area 303, the color filter layer 26 also includes a second color resist 262 and a third color resist 263, the first color resist 261, the second color resist 262 and the third color resist 263 have different light-transmitting colors, the second color resist 262 is arranged on a side of the second touch metal layer 252 away from the first color resist 261, and the third color resist 263 is arranged on a side of the second color resist 262 away from the second touch metal layer 252;

[0041] The first color resist 261 is disposed in the first light-transmitting area 301, the second color resist 262 is disposed in the second light-transmitting area 302, the third color resist 263 is disposed in the third light-transmitting area 303, and the second color resist 262 is disposed in the non-light-transmitting area 201b. By disposing the second color resist on the side of the second touch metal layer away from the first color resist, the third color resist is disposed on the side of the second color resist away from the second touch metal layer, and the second color resist is disposed in the non-light-transmitting area, the second color resist can be used as an insulating layer on the second touch metal layer, and there is no need to provide a touch insulating layer, further reducing the process steps and improving the manufacturing efficiency of the display panel. In addition, the first color resist is disposed in the first light-transmitting area, the second color resist is disposed in the second light-transmitting area, and the third color resist is disposed in the third light-transmitting area, so that the display panel can display normally.

[0042] In some embodiments, Figure 2 , Figure 3As shown, the second color resist 262 and the third color resist 263 are stacked in the non-light-transmitting area 201b. By stacking the second color resist and the third color resist in the non-light-transmitting area, the second color resist and the third color resist have different light-transmitting colors, and the stacking of the second color resist and the third color resist can prevent light from being reflected on the metal, without the need to set a black matrix, further reducing the process steps of the display panel and improving the production efficiency of the display panel.

[0043] Specifically, the display panel in the embodiment of the present application arranges the first color resistance between the first touch metal layer and the second touch metal layer, the first color resistance is arranged in the first light-transmitting area, and the first color resistance is arranged in the non-light-transmitting area. Then, the first color resistance can be used as an insulating layer between the first touch metal layer and the second touch metal layer, the second color resistance is arranged on a side of the second touch metal layer away from the first color resistance, the third color resistance is arranged on a side of the second color resistance away from the second touch metal layer, and the second color resistance is arranged in the second light-transmitting area, the third color resistance is arranged in the third light-transmitting area, and the second color resistance and the third color resistance are stacked and arranged in the non-light-transmitting area. Then, the second color resistance and the third color resistance can be used as the second touch The insulating layer on the touch metal layer does not need to be set, and the second color resist and the third color resist have different light-transmitting colors. The stacked arrangement of the second color resist and the third color resist can prevent light from being reflected on the metal. There is no need to set a black matrix, and the first color resist, the second color resist and the third color resist can be filled in the openings of the first touch metal layer and the second touch metal layer to achieve a filtering effect. The filtering effect of the color film layer is achieved through the first color resist, the second color resist and the third color resist, the effect of the black matrix in reducing reflection is achieved, and the insulating effect of the touch insulating layer is achieved, the black matrix and the touch insulating layer are reduced, the number of mask plates is reduced, and the preparation efficiency of the display panel is improved.

[0044] Specifically, compared with the comparative display device in which the first insulating film, the second insulating film, the black matrix and the color resist need to be separately provided, resulting in a larger thickness of the display panel, the embodiment of the present application adopts three layers of color resist to replace the above-mentioned film layers, which can reduce the thickness of the display panel.

[0045] Specifically, Figure 2 As shown, the display panel 2 may further include a non-display area 202 . The non-display area 202 may be disposed on one side of the display area 201 , or may be disposed around the display area 201 .

[0046] In some embodiments, Figure 3As shown, the first touch metal layer 251 includes a first opening 311, the second touch metal layer 252 includes a second opening 312, the first color resist 261 is disposed in the first opening 311 and on the first touch metal layer 251, and the first color resist 261 has a third opening 313 and a fourth opening 314 in the second light-transmitting area 302 and the third light-transmitting area 303;

[0047] The second color resist 262 is disposed in the second opening 312 , the third opening 313 and the fourth opening 314 , and the second color resist 262 is disposed on the second touch metal layer 252 , and the second color resist 262 has a fifth opening 315 and a sixth opening 316 in the first light-transmitting area 301 and the third light-transmitting area 303 ;

[0048] The third color resist 263 is disposed in the fifth opening 315 and the sixth opening 316 , and the third color resist 263 is disposed on the second color resist 262 . The third color resist 263 has a seventh opening 317 and an eighth opening 318 in the first light-transmitting area 301 and the second light-transmitting area 302 .

[0049] Specifically, Figure 3 As shown, it can be seen that a first color resist 261 is provided between the first touch metal layer 251 and the second touch metal layer 252, so that the first color resist can separate the first touch metal layer 251 and the second touch metal layer 252, and play the role of an insulating layer; at the same time, the first color resist, the second color resist and the third color resist are respectively arranged in the first light-transmitting area, the second light-transmitting area and the third light-transmitting area, which can play the role of filtering light, improve the light-emitting effect, and prevent external light from entering the light-emitting unit to affect the color purity of the light-emitting unit, thereby improving the light-emitting effect; at the same time, the second color resist 262 and the third color resist 263 stacked on the second touch metal layer 252 can block external light from entering, thereby playing the role of a black matrix, and the second color resist and the third color resist can play the role of an insulating layer, so there is no need to separately prepare an insulating layer between the first touch metal layer and the second touch metal layer, there is no need to separately prepare an insulating layer on the second touch metal layer, and there is no need to separately prepare a black matrix, thereby reducing three mask plates and improving preparation efficiency.

[0050] Specifically, the first color resist is disposed to wrap the first touch metal layer, thereby preventing the first touch metal layer from contacting the second touch metal layer and causing a short circuit.

[0051] Specifically, the second color resistance includes a second touch metal layer, so as to prevent the second touch metal layer from contacting other conductive layers and causing a short circuit.

[0052] Specifically, the light-transmitting colors of the first color resist, the second color resist and the third color resist are green, red and blue, respectively, but the embodiments of the present application are not limited to this. It is sufficient that one of the light-transmitting colors of the first color resist, the second color resist and the third color resist is green, one is blue and one is red. For example, the light-transmitting colors of the first color resist, the second color resist and the third color resist are blue, green and red, respectively.

[0053] Specifically, taking the light-transmitting colors of the first color resist, the second color resist and the third color resist as green, red and blue respectively, the red color resist and the blue color resist are stacked on the second touch metal layer, such as Figure 4 As shown, Figure 4 It is a curve diagram of the transmittance of light of different wavelengths when passing through the red color block and the blue color block. Figure 4 The horizontal axis is the wavelength in nanometers, and the vertical axis is the transmittance in %. Figure 4 Curve 1 in the figure is the transmittance curve of light of different wavelengths when passing through the blue color block. Figure 4 Curve 2 in the figure is the transmittance curve of light of different wavelengths when passing through the red color block. Figure 4 It can be seen that when the wavelength of light is 380 nanometers to 580 nanometers, the light can pass through the blue color block, but cannot pass through the red color block, or very little light passes through the red color block, so that when the red color block and the blue color block are stacked, when the wavelength of light is 380 nanometers to 580 nanometers, the light cannot pass through the overlapping part of the red color block and the blue color block, or very little light passes through the stacked red color block and the blue color block; when the wavelength of light is 580 nanometers to 780 nanometers, the light can pass through the red color block, but cannot pass through the blue color block, or very little light passes through the blue color block, so that ... When the color resist and the blue color resist are stacked, when the wavelength of light is 580 nanometers to 780 nanometers, the light cannot pass through the overlap of the red color resist and the blue color resist, or in other words, very little light passes through the stacked red color resist and the blue color resist, so that when the wavelength of light is 380 nanometers to 780 nanometers, it cannot pass through the overlap of the red color resist and the blue color resist. The above wavelength is the wavelength range of visible light, which means that visible light cannot pass through the stack of the red color resist and the blue color resist, that is, the stacked red color resist and the blue color resist can play the role of the black matrix, replacing the black matrix and reducing the reflection of the second touch metal layer. Similarly, due to the different light transmission wavelengths of different color resists, when the second color resist and the third color resist are combinations of color resists of other colors, they can also play the role of the black matrix.

[0054] Specifically, the above embodiment is described by taking the example that the second color resist is set in the fourth opening and covers the side wall of the first color resist to form the sixth opening, but the embodiments of the present application are not limited to this. The second color resist may not be set in the fourth opening. In this case, the sixth opening is set on the fourth opening. Accordingly, the third color resist may be set in the fourth opening and the sixth opening.

[0055] Specifically, the above embodiment is described by taking the example that the third color resist is disposed in the fifth opening and covers the second color resist, but the embodiment of the present application is not limited thereto, and the third color resist may not be disposed in the fifth opening, in which case the seventh opening is disposed on the fifth opening.

[0056] In some embodiments, Figure 3 As shown, the display panel 2 further includes a light-emitting functional layer 23, and the light-emitting functional layer 23 includes a first light-emitting unit 231, a second light-emitting unit 232, and a third light-emitting unit 233. The first light-emitting unit 231 is arranged corresponding to the first color block 261 located in the first light-transmitting area 301, the second light-emitting unit 232 is arranged corresponding to the second color block 262 located in the second light-transmitting area 302, and the third light-emitting unit 233 is arranged corresponding to the third color block 263 located in the third light-transmitting area 303. The area of ​​the seventh opening 317 is larger than the area of ​​the first light-emitting unit 231, and the area of ​​the sixth opening 316 is larger than the area of ​​the third light-emitting unit 233. By making the area of ​​the seventh opening larger than the area of ​​the first light-emitting unit, the light emitted by the first light-emitting unit can pass through the first color block and then be emitted, so as to avoid the second color block and the third color block blocking the light emitted by the first light-emitting unit, thereby improving the light-exiting efficiency of the display panel, and making the area of ​​the sixth opening larger than the area of ​​the third light-emitting unit, so as to avoid the first color block and the second color block blocking the light emitted by the third light-emitting unit, thereby improving the light-exiting efficiency of the display panel.

[0057] Specifically, when forming a display panel, in order to prevent certain deviations from occurring during the preparation process, which may result in blocking of the light-emitting unit, the area of ​​the seventh opening may be made larger than the area of ​​the first light-emitting unit, and the area of ​​the sixth opening may be made larger than the area of ​​the third light-emitting unit. Thus, even if process deviations occur, light can still be emitted from the corresponding openings, thereby improving the light output efficiency of the display panel.

[0058] Specifically, the above embodiment is described by taking the second color resist being arranged in the fourth opening as an example. When the second color resist is not arranged in the fourth opening, the area of ​​the fourth opening can be made larger than the area of ​​the third light-emitting unit, and the area of ​​the sixth opening can be made larger than the area of ​​the third light-emitting unit.

[0059] Specifically, the above embodiment is described by taking the third color resist being arranged in the fifth opening as an example. When the third color resist is not arranged in the fifth opening, the area of ​​the fifth opening can be made larger than the area of ​​the first light-emitting unit, and the area of ​​the seventh opening can be made larger than the area of ​​the first light-emitting unit.

[0060] Specifically, the luminous colors of the first light-emitting unit, the second light-emitting unit and the third light-emitting unit can be the same as the transmittance colors of the first color resist, the second color resist and the third color resist, for example, if the transmittance colors of the first color resist, the second color resist and the third color resist are green, red and blue, respectively, then the luminous colors of the first light-emitting unit, the second light-emitting unit and the third light-emitting unit can be green, red and blue, respectively.

[0061] Specifically, when the luminous colors of the first luminous unit, the second luminous unit, and the third luminous unit are different, the areas of the first luminous unit, the second luminous unit, and the third luminous unit may be different from each other. Since the luminous efficiencies of different luminous materials are different, when setting each luminous material, the areas of each luminous material may be different, that is, the areas of each luminous unit are different, so that the area of ​​the luminous unit with relatively low luminous efficiency is relatively large, so that the luminous efficiency of each luminous unit is similar or even the same, and accordingly, the areas of the openings corresponding to each luminous unit are different, so as to avoid blocking the light emitted by each luminous unit and improve the light extraction efficiency of the display panel. For example, when the luminous colors of the first luminous unit, the second luminous unit, and the third luminous unit are green, red, and blue, respectively, the areas of the first luminous unit, the second luminous unit, and the third luminous unit increase in sequence.

[0062] Specifically, the light-emitting function layer may include a pixel electrode layer, a pixel definition layer, a light-emitting material layer and a common electrode layer, the pixel electrode layer includes a pixel electrode, the pixel definition layer includes vias corresponding to the first light-emitting unit, the second light-emitting unit and the third light-emitting unit, the vias are arranged corresponding to each color resistance, the light-emitting material layer includes a first light-emitting material layer, a second light-emitting material layer and a third light-emitting material layer, the first light-emitting material layer, the second light-emitting material layer and the third light-emitting material layer are respectively arranged in a plurality of vias formed in the pixel definition layer, the pixel electrode, the first light-emitting material layer and the common electrode layer form a first light-emitting unit, the pixel electrode, the second light-emitting material layer and the common electrode layer form a second light-emitting unit, and the pixel electrode, the third light-emitting material layer and the common electrode layer form a third light-emitting unit.

[0063] Specifically, the light emitting colors of the first light emitting unit, the second light emitting unit and the third light emitting unit may all be white. In this case, the areas of the light emitting units may be equal.

[0064] In some embodiments, the area of ​​the eighth opening 318 is greater than or equal to the area of ​​the third opening 313, and the area of ​​the third opening 313 is greater than the area of ​​the second light emitting unit 232. By making the area of ​​the eighth opening greater than or equal to the area of ​​the third opening, and the area of ​​the third opening greater than the area of ​​the second light emitting unit, the first color resistance and the third color resistance can be prevented from blocking the light emitted by the second light emitting unit, thereby improving the light extraction efficiency of the display panel.

[0065] Specifically, when the shape of each light-emitting unit is circular and the shape of each opening is circular, the difference between the diameter of the seventh opening and the diameter of the first light-emitting unit is equal to the difference between the diameter of the third opening and the diameter of the second light-emitting unit, and the difference between the diameter of the third opening and the diameter of the second light-emitting unit is equal to the difference between the diameter of the sixth opening and the third light-emitting unit. This can ensure that the area of ​​each opening is larger than the corresponding light-emitting unit, while avoiding the increase of each opening, which leads to a too small area of ​​the touch metal layer and a poor touch effect.

[0066] The above embodiments are described by taking the shape of each light-emitting unit and the shape of each opening as a circle as an example, but the embodiments of the present application are not limited to this. The shape of each light-emitting unit may be other shapes, the shape of each light-emitting unit may be different, the shape of each opening may be other shapes, the shape of each opening may be different, for example, the shape of the first light-emitting unit, the second light-emitting unit, the third light-emitting unit, the third opening, the sixth opening and the seventh opening are rectangular, or the shape of the first light-emitting unit and the second light-emitting unit are circular, the shape of the third light-emitting unit is elliptical, the shapes of the third opening and the seventh opening are circular, and the shape of the sixth opening is elliptical.

[0067] In some embodiments, the area of ​​the eighth opening 318 is smaller than the area of ​​the third opening 313, and the area of ​​the eighth opening 318 is larger than the area of ​​the second light emitting unit 232. By making the area of ​​the eighth opening smaller than the area of ​​the third opening, and the area of ​​the eighth opening larger than the area of ​​the second light emitting unit, the first color resistance and the third color resistance can be prevented from blocking the light emitted by the second light emitting unit, thereby improving the light extraction efficiency of the display panel.

[0068] In some embodiments, Figure 3As shown, the thickness L2 of the portion of the first color resist 261 located in the first opening 311 is greater than the thickness L1 of the portion of the first color resist 261 located between the first touch metal layer 251 and the second touch metal layer 252; the thickness L4 of the portion of the second color resist 262 located in the second opening 312 and the third opening 313 is greater than the thickness L3 of the portion of the second color resist 262 located on the second touch metal layer 252; the thickness L6 of the portion of the third color resist 263 located in the sixth opening 316 is greater than the thickness L5 of the portion of the third color resist 263 located on the second color resist 262.

[0069] Specifically, when setting the first color resist, the second color resist and the third color resist, the thickness of the color resist located in the light-transmitting area can be larger so that light at various angles can pass through the color resist, while the thickness of the color resist located in the non-light-transmitting area can be relatively smaller, thereby reducing the thickness of the display panel and ensuring the touch performance of the display panel.

[0070] In some embodiments, Figure 3 As shown, the thickness L1 of the portion of the first color resist 261 between the first touch metal layer 251 and the second touch metal layer 252 is equal to the thickness L3 of the portion of the second color resist 262 on the second touch metal layer 252; the thickness L3 of the portion of the second color resist 262 on the second touch metal layer 252 is equal to the thickness L5 of the portion of the third color resist 263 on the second color resist 262. By making the thickness of the portion of the first color resist between the first touch metal layer and the second touch metal layer, the thickness of the portion of the second color resist on the second touch metal layer, and the thickness of the portion of the third color resist on the third color resist equal, the insulation effect of the first color resist is better, the stacking light blocking effect of the second color resist and the third color resist is better, and when the first color resist, the second color resist, and the third color resist are used to replace the insulating film and the black matrix, the touch performance of the display panel can be maintained.

[0071] In some embodiments, the thickness L1 of the portion of the first color resist 261 between the first touch metal layer 251 and the second touch metal layer 252 is equal to the sum of the thickness L3 of the portion of the second color resist 262 on the second touch metal layer 252 and the thickness L5 of the portion of the third color resist 263 on the second color resist 262. By making the thickness of the portion of the first color resist between the first touch metal layer and the second touch metal layer equal to the sum of the thickness of the portion of the second color resist on the second touch metal layer and the thickness of the portion of the third color resist on the second color resist, the touch performance of the display panel can be maintained when the first color resist, the second color resist, and the third color resist are used to replace the insulating film and the black matrix.

[0072] Specifically, it can be understood that since the touch insulating film is generally formed of an inorganic layer, the dielectric constant of the touch insulating film ranges from 3 to 5 farads / micrometer, and the thickness of the touch insulating film ranges from 0.5 micrometers to 1 micrometer, and the color resist is generally formed of an organic photoresist, and the dielectric constant of the color resist ranges from 6 to 8 farads / micrometer. Therefore, according to the capacitance formula, when the dielectric constant increases, the thickness needs to be increased to ensure that the capacitance remains unchanged so that the display panel has the same touch effect. Therefore, the thickness of the first color resist located between the first touch metal layer and the second touch metal layer can be 1 micrometer to 3 micrometers, the thickness of the second color resist located on the second touch metal layer can be 1 micrometer to 3 micrometers, and the thickness of the third color resist located on the second touch metal layer can be 1 micrometer to 3 micrometers.

[0073] In some embodiments, the maximum thickness of the first color resist is ten to fifty times the thickness of the first touch metal layer, the maximum thickness of the second color resist is ten to fifty times the thickness of the first touch metal layer, and the maximum thickness of the third color resist is ten to fifty times the thickness of the first touch metal layer. This allows the touch layer to maintain its capacitance performance while achieving light filtering, resulting in better touch performance.

[0074] Specifically, the thickness of the first touch metal layer and the second touch metal layer ranges from 0.06 micrometers to 0.1 micrometers.

[0075] Specifically, the maximum thickness of the first color resist, the maximum thickness of the second color resist, and the maximum thickness of the third color resist are thirty times to fifty times the thickness of the first touch metal layer.

[0076] In some embodiments, Figure 3 As shown, the thickness L2 of the portion of the first color resist 261 disposed in the first light-transmitting area 301 is less than the thickness L4 of the portion of the second color resist 262 disposed in the second light-transmitting area 302, and the thickness L4 of the portion of the second color resist 262 disposed in the second light-transmitting area 302 is less than the thickness L6 of the portion of the third color resist 263 disposed in the third light-transmitting area 303. By increasing the thickness of the portions of the first color resist, the second color resist, and the third color resist located in the light-transmitting area in sequence, the second color resist can be covered on the second touch metal layer, and the third color resist can be covered on the second color resist, so that the first color resist, the second color resist, and the third color resist replace the touch insulating film and the black matrix, and filter each light-emitting unit.

[0077] Specifically, Figure 3 As shown, the display panel 2 further includes a driving circuit layer 22 and a packaging layer 24 . The driving circuit layer 22 is disposed between the substrate 21 and the light-emitting functional layer 23 .

[0078] Specifically, Figure 3As shown, the display panel 2 further includes a planar layer 27 , and the planar layer 27 is disposed on the color filter layer 26 .

[0079] Specifically, the encapsulation layer includes a first inorganic layer, an organic layer and a second inorganic layer.

[0080] Specifically, the above embodiments describe the display panel in detail from the perspective of each film layer, the design of each film layer, the relationship between each film layer, etc. It can be understood that when there is no conflict between the embodiments, the embodiments can be combined. For example, the thickness of the portion of the first color resist located in the first opening is greater than the thickness of the portion of the first color resist located between the first touch metal layer and the second touch metal layer; the thickness of the portion of the second color resist located in the second opening and the third opening is greater than the thickness of the portion of the second color resist located on the second touch metal layer; the thickness of the portion of the third color resist located in the sixth opening is greater than the thickness of the portion of the third color resist located on the second color resist; the thickness of the portion of the first color resist located between the first touch metal layer and the second touch metal layer is equal to the thickness of the portion of the second color resist located on the second touch metal layer; the thickness of the portion of the second color resist located on the second touch metal layer is equal to the thickness of the portion of the third color resist located on the second color resist.
