Description

Display panel and display device Technical Field

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

[0002] OLED (Organic Light-Emitting Diode) displays are widely used due to their advantages such as self-emission, wide color gamut, low power consumption, and flexibility. To reduce thickness, existing OLED displays use DOT (Direct On Cell Touch) technology to fabricate the touch layer. Furthermore, to address the issues of large polarizer thickness leading to low luminous efficiency and high power consumption due to light absorption, a Pol Less Panel (PLP) technology has been proposed. This technology replaces the polarizer with a black matrix and color resist, reducing external reflected light while improving the transmittance of the OLED display. However, the fabrication process of OLED displays requires the fabrication of the touch layer, black matrix, and color resist, resulting in a large number of masks, a complex fabrication process, and low fabrication efficiency.

[0003] Therefore, existing OLED display devices suffer from the technical problem of low fabrication efficiency due to the need to separately fabricate the touch layer, black matrix, and color resist. Invention Overview

[0004] This application provides a display panel and a display device to solve the technical problem that existing OLED display devices require separate fabrication of the touch layer, black matrix and color resist, resulting in low fabrication efficiency.

[0005] In a first aspect, embodiments of this application provide a display panel, the display panel including a display area, the display area including a plurality of light-transmitting areas and a plurality of light-blocking areas, the display panel including:

[0006] Substrate;

[0007] A touch layer is disposed on one side of the substrate, including a first touch metal layer and a second touch metal layer, wherein the second touch metal layer is disposed on the side of the first touch metal layer away from the substrate;

[0008] A color filter layer is disposed on one side of the substrate, and the color filter layer includes at least a first color resist, which is disposed between the first touch metal layer and the second touch metal layer;

[0009] The first color resist is disposed in the non-transparent area, and the first color resist is disposed in a portion of the transparent area.

[0010] Secondly, embodiments of this application provide a display device, which includes a display panel as described in any of the above embodiments. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] In the description of this application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular, for example, the range of included angles between 80° and 100° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel, for example, the range of completely parallel angles between 10° is considered parallel.

[0020] In order to illustrate the principle of the technical problem arising in the embodiments of this application, the embodiments of this application provide a contrast display device. It should be understood that the contrast display device cannot be regarded as the prior art in the embodiments of this application. As shown in Figure 1, the contrast display device includes a light-emitting film, an encapsulation film 12, a touch film, a filter film, a black matrix film 14, and a planarization 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 color resist 151, a blue color resist 152, and a green color resist 153. When the contrast display device is displayed, 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 onto the corresponding color resist, and then emitted from the contrast display device. As can be seen from Figure 1, the first metal film, the first insulating film, the second metal film, the second insulating film, the black matrix film, the red color resist, the blue color resist, and the green color resist need to be fabricated on the encapsulation layer, resulting in a large number of photomasks required for the contrast display device, high cost, complex fabrication process, and low fabrication efficiency of the display device. Therefore, existing OLED display devices suffer from the technical problem of low fabrication efficiency due to the need to separately fabricate the touch layer, black matrix, and color resist.

[0021] This application provides a display panel and a display device to address the aforementioned technical problems.

[0022] Figure 2 is a plan view of the display panel provided in an embodiment of this application. Figure 3 is a cross-sectional view of the display panel provided in an embodiment of this application. Figure 4 is a graph showing the transmittance of light of different wavelengths passing through red and blue color resists provided in an embodiment of this application. Figure 5 is a structural diagram of the display panel corresponding to each step of the manufacturing method of the display panel provided in an embodiment of this application.

[0023] As shown in Figures 2 and 3, this application embodiment provides a display panel 2, which includes a display area 201. The display area 201 includes multiple light-transmitting areas 201a and multiple light-blocking 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 disposed on one side of the substrate 21 and includes a first touch metal layer 251 and a second touch metal layer 252. The second touch metal layer 252 is disposed on the side of the first touch metal layer 251 away from the substrate 21. The color filter layer 26 is disposed on one side of the substrate 21 and includes at least a first color resist 261. The first color resist 261 is disposed between the first touch metal layer 251 and the second touch metal layer 252.

[0024] The first color resist 261 is disposed in the non-transparent area 201b, and the first color resist 261 is disposed in a portion of the transparent area 201a.

[0025] This application provides a display panel and a display device. The display panel can serve as an insulating layer between the first touch metal layer and the second touch metal layer by disposing a first color resist between the first and second touch metal layers. This reduces the fabrication efficiency of the display panel by at least one step in the process of preparing the insulating layer between the first and second touch metal layers. Furthermore, the first color resist can be placed in the partially transparent area to filter light, enabling the display panel to display normally.

[0026] In some embodiments, as shown in Figures 2 and 3, 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 disposed on the side of the second touch metal layer 252 away from the first color resist 261, and the third color resist 263 is disposed on the side of the second color resist 262 away from the second touch metal layer 252.

[0027] The first color resist 261 is disposed within the first light-transmitting area 301, the second color resist 262 is disposed within the second light-transmitting area 302, and the third color resist 263 is disposed within the third light-transmitting area 303. The second color resist 262 is disposed within 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, and the third color resist on the side of the second color resist away from the second touch metal layer, and by disposing the second color resist within the non-light-transmitting area, the second color resist can be used as an insulating layer on the second touch metal layer, eliminating the need for a separate touch insulating layer. This further reduces process steps and improves the manufacturing efficiency of the display panel. Furthermore, the placement of the first, second, and third color resists within the first, second, and third light-transmitting areas ensures normal display of the display panel.

[0028] In some embodiments, as shown in Figures 2 and 3, the second color resist 262 and the third color resist 263 are stacked within the opaque area 201b. By stacking the second and third color resists within the opaque area, and considering that the second and third color resists have different light-transmitting colors, the stacked arrangement of the second and third color resists can prevent light reflection from occurring on the metal surface. This eliminates the need for a black matrix, further reducing the number of processing steps in the display panel and improving its manufacturing efficiency.

[0029] Specifically, in the embodiment of this application, the display panel, by placing a first color resist between a first touch metal layer and a second touch metal layer, with the first color resist disposed in a first light-transmitting area and a second color resist disposed in a non-light-transmitting area, can use the first color resist as an insulating layer between the first and second touch metal layers. The second color resist is disposed on the side of the second touch metal layer away from the first color resist, and the third color resist is disposed on the side of the second color resist away from the second touch metal layer. Furthermore, the second and third color resists are stacked in the non-light-transmitting area, thus serving as a second touch metal layer. The insulating layer on the control metal layer eliminates the need for a touch insulating layer. Furthermore, the second and third color resists have different light-transmitting colors. The stacked arrangement of the second and third color resists prevents light reflection from the metal, eliminating the need for a black matrix. The first, second, and third color resists can fill the openings in the first and second touch metal layers, achieving a filtering effect. Thus, the first, second, and third color resists achieve the filtering effect of the color filter layer, while the black matrix reduces reflection and provides insulation for the touch insulating layer. This reduces the number of black matrices and touch insulating layers, decreases the number of photomasks, and improves the manufacturing efficiency of the display panel.

[0030] Specifically, compared to the comparison display device which requires the separate setting of a first insulating film, a second insulating film, a black matrix, and a color resist, resulting in a larger thickness of the display panel, the embodiments of this application use three layers of color resist to replace the above-mentioned film layers, which can reduce the thickness of the display panel.

[0031] Specifically, as shown in Figure 2, the display panel 2 may also include a non-display area 202, which may be located on one side of the display area 201 or may be arranged around the display area 201.

[0032] In some embodiments, as shown in FIG3, 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;

[0033] 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. 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.

[0034] The third color resist 263 is disposed within 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.

[0035] Specifically, as shown in Figure 3, 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 act as an insulating layer. At the same time, the first color resist, the second color resist, and the third color resist are respectively disposed in the first light-transmitting area, the second light-transmitting area, and the third light-transmitting area, which can filter light, improve the light emission effect, and prevent external light from entering the light-emitting unit and affecting the color purity of the light-emitting unit, thereby improving the light emission effect. Meanwhile, the second color resist 262 and the third color resist 263, which are stacked on the second touch metal layer 252, can block external light from entering, thereby acting as a black matrix. The second color resist and the third color resist can also act as an insulating layer, so there is no need to separately prepare the insulating layer between the first touch metal layer and the second touch metal layer, no need to separately prepare the insulating layer on the second touch metal layer, and no need to separately prepare the black matrix, thereby reducing the number of three photomasks and improving the preparation efficiency.

[0036] Specifically, the first color resist is wrapped around the first touch metal layer to prevent short circuits from occurring when the first touch metal layer comes into contact with the second touch metal layer.

[0037] Specifically, the second color resist includes a second touch metal layer to prevent short circuits from occurring when the second touch metal layer comes into contact with other conductive layers.

[0038] Specifically, the light-transmitting colors of the first, second, and third color resists are green, red, and blue, respectively. However, the embodiments of this application are not limited to this. One of the light-transmitting colors of the first, second, and third color resists can be green, one can be blue, and one can be red. For example, the light-transmitting colors of the first, second, and third color resists are blue, green, and red, respectively.

[0039] Specifically, taking the first, second, and third color resists as examples where the light-transmitting colors are green, red, and blue respectively, the red and blue color resists are stacked on the second touch metal layer, as shown in Figure 4. Figure 4 is a curve showing the transmittance of light of different wavelengths passing through the red and blue color resists. The horizontal axis in Figure 4 represents wavelength in nanometers, and the vertical axis represents transmittance in percentage. Curve 1 in Figure 4 shows the transmittance of light of different wavelengths passing through the blue color resist, and curve 2 shows the transmittance of light of different wavelengths passing through the red color resist. As can be seen from Figure 4, when the wavelength of light is between 380 nanometers and 580 nanometers, light can pass through the blue color resist, but cannot pass through the red color resist, or very little light passes through the red color resist. Therefore, when the red and blue color resists are stacked, light of wavelengths between 380 nanometers and 580 nanometers cannot pass through the red color resist. At the overlap of the red and blue color resists, or in other words, very little light passes through the stacked red and blue color resists. When the wavelength of light is between 580 nm and 780 nm, light can pass through the red color resist, but very little light can pass through the blue color resist. Therefore, when the red and blue color resists are stacked, light at wavelengths between 580 nm and 780 nm cannot pass through the overlap of the red and blue color resists, or in other words, very little light passes through the stacked red and blue color resists. Consequently, light at wavelengths between 380 nm and 780 nm cannot pass through the overlap of the red and blue color resists. Since these wavelengths are within the visible light range, it means that visible light cannot pass through the stacked area of ​​the red and blue color resists. This means that the stacked red and blue color resists can act as a black matrix, replacing the black matrix and reducing reflection from the second touch metal layer. Similarly, since different color resists have different light transmission wavelengths, when the second and third color resists are combinations of color resists of other colors, they can also serve as a black matrix.

[0040] Specifically, the above embodiment is illustrated by taking the example that the second color resist is placed in the fourth opening and covers the side wall of the first color resist to form the sixth opening. However, the embodiments of this application are not limited to this. The second color resist may not be placed in the fourth opening. In this case, the sixth opening is placed on the fourth opening. Correspondingly, the third color resist may be placed in both the fourth and sixth openings.

[0041] Specifically, the above embodiment is illustrated by taking the example that the third color resist is set in the fifth opening and covers the second color resist. However, the embodiments of this application are not limited to this. The third color resist may not be set in the fifth opening. In this case, the seventh opening is set on the fifth opening.

[0042] In some embodiments, as shown in FIG3, the display panel 2 further includes a light-emitting functional layer 23, the light-emitting functional layer 23 including 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 correspondingly disposed with respect to the first color resist 261 located in the first light-transmitting area 301, the second light-emitting unit 232 is correspondingly disposed with respect to the second color resist 262 located in the second light-transmitting area 302, and the third light-emitting unit 233 is correspondingly disposed with respect to the third color resist 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 resist and then be emitted, avoiding the second and third color resists from blocking the light emitted by the first light-emitting unit, thus improving the light emission efficiency of the display panel. Similarly, by making the area of ​​the sixth opening larger than the area of ​​the third light-emitting unit, the first and second color resists are avoided from blocking the light emitted by the third light-emitting unit, thus improving the light emission efficiency of the display panel.

[0043] Specifically, in order to prevent certain deviations from occurring during the manufacturing process that could block the light-emitting units, the area of ​​the seventh opening can be larger than the area of ​​the first light-emitting unit, and the area of ​​the sixth opening can be larger than the area of ​​the third light-emitting unit. Thus, even if there are process deviations, light can still be emitted from the corresponding openings, improving the light emission efficiency of the display panel.

[0044] Specifically, the above embodiment is illustrated by taking the second color resist as being placed in the fourth opening as an example. When the second color resist is not placed in the fourth opening, the area of ​​the fourth opening can be larger than the area of ​​the third light-emitting unit, and the area of ​​the sixth opening can be larger than the area of ​​the third light-emitting unit.

[0045] Specifically, the above embodiment is illustrated by taking the third color resist as being placed inside the fifth opening as an example. When the third color resist is not placed inside the fifth opening, the area of ​​the fifth opening can be larger than the area of ​​the first light-emitting unit, and the area of ​​the seventh opening can be larger than the area of ​​the first light-emitting unit.

[0046] Specifically, the light emission colors of the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit can be the same as the light transmission colors of the first color resist, the second color resist, and the third color resist, respectively. For example, if the light transmission colors of the first color resist, the second color resist, and the third color resist are green, red, and blue, respectively, then the light emission 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.

[0047] Specifically, when the first, second, and third light-emitting units emit different colors, their areas can be different. Since different light-emitting materials have different luminous efficiencies, the areas of each material can be varied, resulting in different areas for each light-emitting unit. This allows the areas of units with relatively lower luminous efficiency to be relatively larger, thus making the luminous efficiencies of each unit similar or even the same. Consequently, the areas of the openings corresponding to each light-emitting unit can be different, preventing obstruction of the light emitted by each unit and improving the light emission efficiency of the display panel. For example, when the first, second, and third light-emitting units emit green, red, and blue colors respectively, their areas increase sequentially.

[0048] Specifically, the light-emitting functional 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 correspondingly disposed with each color resist. 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 disposed in the multiple vias formed by the pixel definition layer. The pixel electrode, the first light-emitting material layer, and the common electrode layer form the first light-emitting unit. The pixel electrode, the second light-emitting material layer, and the common electrode layer form the second light-emitting unit. The pixel electrode, the third light-emitting material layer, and the common electrode layer form the third light-emitting unit.

[0049] Specifically, the first, second, and third light-emitting units can all emit white light. In this case, the area of ​​each light-emitting unit can be equal.

[0050] 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 and third color resistors can be prevented from blocking the light emitted by the second light-emitting unit, thereby improving the light emission efficiency of the display panel.

[0051] Specifically, when all light-emitting units and openings are 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. Similarly, 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 diameter of the third light-emitting unit. This ensures that the area of ​​each opening is larger than the corresponding light-emitting unit, while avoiding the situation where increasing the size of the openings would result in an excessively small area of ​​the touch-sensitive metal layer, leading to a deterioration in the touch performance.

[0052] The above embodiments are illustrated using the example of circular shapes for each light-emitting unit and each opening. However, the embodiments of this application are not limited to this. The shapes of each light-emitting unit can be other shapes, and the shapes of each light-emitting unit can be different. The shapes of each opening can be other shapes, and the shapes of each opening can be different. For example, the shapes 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 can be rectangular, or the shapes of the first light-emitting unit and the second light-emitting unit can be circular, the shape of the third light-emitting unit can be elliptical, the shapes of the third opening and the seventh opening can be circular, and the shape of the sixth opening can be elliptical.

[0053] 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 and third color resistors can be prevented from blocking the light emitted by the second light-emitting unit, thereby improving the light emission efficiency of the display panel.

[0054] In some embodiments, as shown in FIG3, the thickness L2 of the portion of the first color resist 261 located within 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 between 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; and the thickness L6 of the portion of the third color resist 263 located within 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.

[0055] Specifically, when setting the first, second, and third color resists, the thickness of the color resist located in the light-transmitting area can be larger, allowing light from all angles to 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 while ensuring the touch performance of the display panel.

[0056] In some embodiments, as shown in FIG3, 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 is equal to the thickness L3 of the portion of the second color resist 262 located on the second touch metal layer 252; the thickness L3 of the portion of the second color resist 262 located on the second touch metal layer 252 is equal to the thickness L5 of the portion of the third color resist 263 located on the second color resist 262. By making the thicknesses of the portion of the first color resist located between the first and second touch metal layers, the portion of the second color resist located on the second touch metal layer, and the portion of the third color resist located on the third color resist equal, the insulation effect of the first color resist is better, the light blocking effect of the stacked second and third color resists is better, and the touch performance of the display panel can be maintained when the first, second, and third color resists are used to replace the insulating film and the black matrix.

[0057] In some embodiments, 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 is equal to the sum of the thickness L3 of the portion of the second color resist 262 located on the second touch metal layer 252 and the thickness L5 of the portion of the third color resist 263 located on the second color resist 262. By making the thickness of the portion of the first color resist located between the first and second touch metal layers equal to the sum of the thickness of the portion of the second color resist located on the second touch metal layer and the thickness of the portion of the third color resist located on the second color resist, the touch performance of the display panel can be maintained when the first, second, and third color resists are used to replace the insulating film and the black matrix.

[0058] Specifically, it can be understood that since touch insulating films are generally formed using inorganic layers, the dielectric constant of touch insulating films ranges from 3 to 5 farads / micrometer, and the thickness of touch insulating films ranges from 0.5 micrometers to 1 micrometer. On the other hand, color resists are generally formed using organic photoresists, and the dielectric constant of color resists 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 portion of the first color resist located between the first touch metal layer and the second touch metal layer can be 1 to 3 micrometers, the thickness of the portion of the second color resist located on the second touch metal layer can be 1 to 3 micrometers, and the thickness of the portion of the third color resist located on the second touch metal layer can be 1 to 3 micrometers.

[0059] 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 capacitive properties while achieving light filtering, resulting in better touch performance.

[0060] Specifically, the thickness of the first touch metal layer and the second touch metal layer ranges from 0.06 micrometers to 0.1 micrometers.

[0061] 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 to fifty times the thickness of the first touch metal layer.

[0062] In some embodiments, as shown in FIG3, 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, second, and third color resists located in the light-transmitting areas sequentially, the second color resist can cover the second touch metal layer, and the third color resist can cover the second color resist, thereby enabling the first, second, and third color resists to replace the touch insulating film and the black matrix, and to filter light for each light-emitting unit.

[0063] Specifically, as shown in Figure 3, the display panel 2 also includes a driving circuit layer 22 and an encapsulation layer 24, with the driving circuit layer 22 disposed between the substrate 21 and the light-emitting functional layer 23.

[0064] Specifically, as shown in Figure 3, the display panel 2 also includes a planarization layer 27, which is disposed on the color filter layer 26.

[0065] Specifically, the encapsulation layer includes a first inorganic layer, an organic layer, and a second inorganic layer.
