[0090] In the process of developing this application, the inventors discovered the following problem in the related technology: some pixel units have display abnormalities, which to some extent affect the display effect of the display panel 10 and ultimately affect its performance, reducing the reliability of the display panel 10.

[0091] Based on this, this application provides a display panel 10 to at least alleviate or improve the above-mentioned technical problems to a certain extent.

[0092] This application provides a display panel 10, please refer to... Figure 1 .

[0093] Please see Figure 2 The display panel 10 includes a plurality of repeating pixel units 1 arranged in an array, and each pixel unit 1 includes a plurality of sub-pixels 101. The display panel 10 also includes an isolation structure 2, which encloses a plurality of isolation openings 201, and a sub-pixel 101 is located in one isolation opening 201. At this time, any two adjacent sub-pixels 101 can be separated by the isolation structure 2 with the isolation opening 201.

[0094] Please see Figure 2 Each pixel unit 101 is arranged in an array along the first direction X and the second direction Y.

[0095] The isolation structure mentioned below is further described in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, PCT / CN2024 / 099072, CN117979755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, and CN117500332A for reference.

[0096] Please see Figure 2 Any pixel unit 1 includes multiple sub-pixels 101, and at least some pixel units 1 include adjacent first sub-pixels R and second sub-pixels G. For the same pixel unit 1, the minimum width of the isolation structure 2 between the first sub-pixel R and the second sub-pixel G is a first width a; between two adjacent pixel units 1, the first sub-pixel R located in one pixel unit 1 is adjacent to the second sub-pixel G located in the other pixel unit 1, and the minimum width of the isolation structure 2 between them is a second width b, where the first width a is greater than the second width b.

[0097] It should be noted that the aforementioned width is the distance between two adjacent isolation openings 201 at corresponding positions of the isolation structure 2. Since the shape of the isolation openings 201 in the thickness direction of the display panel 10 may be different, such as circular, elliptical, rectangular, or strip-shaped, the distance between two adjacent isolation openings 201 may be within a certain range. To better define the aforementioned first width a and second width b, both are set as the minimum distance between two adjacent isolation openings 201, that is, the minimum width value of the isolation structure 2 located between two adjacent isolation openings 201.

[0098] In the display panel 10 provided in this application embodiment, each sub-pixel 101 is separated by an isolation structure 2 having an isolation opening 201. By adjusting the size of the isolation opening 201 used to accommodate and separate the sub-pixels 101, the second width b is made smaller than the first width a, which can effectively reduce the spacing between two adjacent pixel units 1 and increase the opening size of the isolation opening 201 corresponding to the first sub-pixel R located at the edge of the pixel unit 1 in that direction, thereby improving the aperture ratio of the isolation opening 201 and achieving the purpose of improving the display effect and performance of the display panel 10.

[0099] It should be noted that when differentiating the width of the isolation structure 2 at different locations, it is necessary to ensure that the above-mentioned differential design does not affect the normal function of other film layers and devices of the display panel 10.

[0100] For example, if shortening the first width a would affect other components of the display panel 10, then the second width b should be reduced to increase the opening size of the isolation opening 201 corresponding to the first sub-pixel R, thereby increasing the aperture ratio of the display panel 10, provided that the first width a meets the existing design requirements.

[0101] In some embodiments, two adjacent pixel units 1 are located in the same column and arranged along the first direction X. Please refer to [link / reference]. Figure 2 Different pixel units 1 can be powered by different array circuits. In the first direction X, pixel units 1 located at different positions are different pixel units 1.

[0102] In some embodiments, the first sub-pixel R and the second sub-pixel G located in the same pixel unit 1 are arranged along the first direction X. See also Figure 2 At this point, all the first sub-pixels R and second sub-pixels G are arranged in a repeating pattern along the first direction X, and the width of the isolation structure 2 between the first sub-pixels R and second sub-pixels G at different positions is different. The first width a and the second width b are both the widths of the isolation structure 2 along the first direction X.

[0103] For details, please refer to Figure 2 and Figure 3 The first sub-pixel R and the second sub-pixel G emit different colors.

[0104] The first sub-pixel R can be defined as emitting red light, and the second sub-pixel G as emitting green light.

[0105] For two adjacent pixel units 1 along the first direction X, the width of the isolation structure 2 between the first sub-pixel R in one pixel unit 1 and the second sub-pixel G in the other pixel unit 1 is the second width b.

[0106] Please see Figure 2 and Figure 3 The light-emitting area of ​​the first sub-pixel R is smaller than the light-emitting area of ​​the second sub-pixel G.

[0107] In the first direction X, the length of the first sub-pixel R is the first length, and the length of the second sub-pixel G is the second length, with the first length being less than the second length.

[0108] In other embodiments, the plurality of sub-pixels 101 further includes a third sub-pixel B. At least some pixel units 1 include the third sub-pixel B; see [link to relevant documentation]. Figure 3 For the same pixel unit 1, the first sub-pixel R and the second sub-pixel G are both located on the same side of the third sub-pixel B and are adjacent to the third sub-pixel B.

[0109] Specifically, the third sub-pixel B is defined as being located on one side of the first sub-pixel R and / or the second sub-pixel G in the second direction Y. The second direction Y is orthogonal to the first direction X.

[0110] The light-emitting area of ​​the first sub-pixel R and the light-emitting area of ​​the second sub-pixel G are both smaller than the light-emitting area of ​​the third sub-pixel B.

[0111] In some embodiments, the emission color of the third sub-pixel B is different from the emission color of the first sub-pixel R and the emission color of the second sub-pixel G.

[0112] The first sub-pixel R is defined as emitting red, the second sub-pixel G as emitting green, and the third sub-pixel B as emitting blue. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 For the same pixel unit 1, red and green pixels are arranged along the first direction X, and blue pixels are located to the right of red and green pixels.

[0113] In the second direction Y, at least one of the first sub-pixel R and the second sub-pixel G at least partially overlaps with the third sub-pixel B. (See also...) Figure 3 .

[0114] In some embodiments, at least a portion of the sub-pixels 101 may be a strip or rectangular structure extending along the first direction X. (See also...) Figure 3In the figure, each sub-pixel 101 is a rounded rectangle or a similar rounded rectangle structure extending along the first direction X. Correspondingly, the opening shape of the isolation opening 201 on the isolation structure 2 can also be a rounded rectangle or a similar rounded rectangle structure that matches the shape of each sub-pixel 101.

[0115] Please see Figure 3 In the first direction X, the length of the third sub-pixel B is the third length, which is greater than either the first length or the second length, and the sum of the first length and the second length is less than the third length.

[0116] To further increase the aperture ratio of at least some pixel units 1, in some embodiments, the isolation structure 2 also has a third width c and / or a fourth width d.

[0117] For the same pixel unit 1, the minimum width of the isolation structure 2 between the first sub-pixel R and the third sub-pixel B is the third width c, which is less than the first width a; and / or, for the same pixel unit 1, the minimum width of the isolation structure 2 between the second sub-pixel G and the third sub-pixel B is the fourth width d, which is less than the first width a.

[0118] For the same pixel unit 1, by adjusting the distance between the first sub-pixel R and the third sub-pixel B, the third width c can be made smaller than the first width a. At this time, at least one of the first sub-pixel R and the third sub-pixel B can obtain a larger opening size in the second direction Y, which helps to improve the opening ratio of the isolation opening 201, thereby improving the display effect of the display panel 10 and improving the performance of the display panel 10.

[0119] Similarly, for the same pixel unit 1, by adjusting the distance between the second sub-pixel G and the third sub-pixel B, the fourth width d can be made smaller than the first width a. At this time, at least one of the second sub-pixel G and the third sub-pixel B can obtain a larger opening size in the second direction Y, which helps to improve the aperture ratio of the isolation opening 201 and achieve the purpose of improving the display effect of the display panel 10 and improving the performance of the display panel 10.

[0120] For example, while ensuring that the first width a remains unchanged, by reducing the third width c and / or the fourth width d to be smaller than the first width a, the opening size of the corresponding isolation opening 201 in the second direction Y can be increased, thereby improving the aperture ratio of the isolation structure 2 in the display panel 10. From the perspective of the display panel 10, the smaller the width of the isolation structure 2 between two adjacent sub-pixels 101, the smaller the spacing between the corresponding sub-pixels 101, and the larger the opening size of the isolation opening 201 corresponding to the sub-pixel 101.

[0121] Please see Figure 3 In some embodiments, the dimensions of the third width c and the fourth width d can be set to be the same, or to remain basically the same within the range of processing error.

[0122] The width of the first sub-pixel R in the second direction Y and the width of the second sub-pixel G in the second direction Y can also be the same or basically the same.

[0123] Please see Figure 2 and Figure 3 The pixel unit 1 provided in this embodiment includes three sub-pixels 101, and the pixel unit 1 is arranged in an array along the first direction X and the second direction Y.

[0124] In other embodiments, at least some pixel units 1 may be configured to include six or more sub-pixels 101, which may be arranged according to the arrangement rules described above.

[0125] It should be noted that all sub-pixels 101 located in the same pixel unit 1 are powered by the same row array circuit.

[0126] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 The isolation structure 2 in the figure has multiple isolation openings 201, which are used to separate different sub-pixels 101.

[0127] The display panel 10 also includes a substrate 3, and the isolation structure 2 is located on one side of the substrate 3. The isolation structure 2 includes a crown 21 and a support 22, wherein the crown 21 is located on the side of the support 22 away from the substrate 3, and the crown 21 and the support 22 together form the isolation opening 201, and the orthographic projection of the support 22 on the substrate 3 is located within the orthographic projection of the crown 21 on the substrate 3.

[0128] The support portion 22 located between two adjacent isolation openings 201 can have a structure that is trapezoidal, rectangular, or inverted trapezoidal. In this embodiment, the support portion 22 is an inverted trapezoidal structure.

[0129] The crown 21 is located at the end of the support 22 facing away from the substrate 3. The structure of the crown 21 located between two adjacent isolation openings 201 can be trapezoidal or rectangular.

[0130] It should be noted that the support portion 22 can be a single-layer structure or a multi-layer structure. When the support portion 22 is a multi-layer structure, it can be configured to include at least two stacked sub-support portions. The orthographic projection of the sub-support portion farther from the substrate 3 onto the substrate 3 is located within the orthographic projection range of the sub-support portion closer to the substrate 3 onto the substrate 3.

[0131] The sidewall of the sub-support portion farther from the substrate 3 facing the isolation opening 201 is offset towards the side farther from the isolation opening 201, relative to the sidewall of the sub-support portion closer to the substrate 3, so that the cross-sectional sidewall of the isolation structure 2 presents a roof-like shape.

[0132] Of course, in other similar embodiments, the dimensional and projection relationships between the sequentially stacked sub-supports and crown 21 can also be adaptively adjusted according to actual processing needs.

[0133] Please see Figure 4 In the figure, two spaced-apart openings 201 are filled with a first color sub-pixel R and a second color sub-pixel G, respectively, and the two sub-pixels 101 belong to the same pixel unit 1. For the same pixel unit 1, the edge of the crown 21 located between the first sub-pixel R and the second sub-pixel G near the first sub-pixel R is the first edge 2101, and the edge of the crown 21 located between the first sub-pixel R and the second sub-pixel G near the second sub-pixel G is the second edge 2102. The minimum distance between the orthographic projection of the first edge 2101 and the orthographic projection of the second edge 2102 on the substrate 3 along the first direction X is the first width a.

[0134] Please see Figure 5 In the figure, two spaced-apart openings 201 are filled with a first color sub-pixel R and a second color sub-pixel G, respectively, and the two sub-pixels 101 belong to different pixel units 1. For two adjacent pixel units 1, the crown 21 located between the first sub-pixel R in one pixel unit 1 and the second sub-pixel G in the other pixel unit 1, near the edge of the first sub-pixel R, is the third edge 2103, and the crown 21 located between the first sub-pixel R in one pixel unit 1 and the second sub-pixel G in the other pixel unit 1, near the edge of the second sub-pixel G, is the fourth edge 2104. The minimum distance between the orthographic projection of the third edge 2103 on the substrate 3 and the orthographic projection of the fourth edge 2104 on the substrate 3 along the first direction X is the second width b.

[0135] Please see Figure 6 In the figure, two spaced-apart openings 201 are filled with a first color sub-pixel R and a third color sub-pixel B, respectively, and the two sub-pixels 101 belong to the same pixel unit 1. For the same pixel unit 1, the edge of the crown 21 between the first sub-pixel R and the third sub-pixel B near the first sub-pixel R is the fifth edge 2105, and the edge of the crown 21 between the first sub-pixel R and the third sub-pixel B near the third sub-pixel B is the sixth edge 2106. The minimum distance between the orthographic projection of the fifth edge 2105 on the substrate 3 and the orthographic projection of the sixth edge 2106 on the substrate 3 along the second direction Y is the third width c.

[0136] Please see Figure 7 In the figure, two spaced-apart openings 201 are filled with a second color sub-pixel G and a third color sub-pixel B, respectively, and the two sub-pixels 101 belong to the same pixel unit 1. For the same pixel unit 1, the edge of the crown 21 between the second sub-pixel G and the third sub-pixel B near the second sub-pixel G is the seventh edge 2107, and the edge of the crown 21 between the second sub-pixel G and the third sub-pixel B near the third sub-pixel B is the eighth edge 2108. The minimum distance between the orthographic projection of the seventh edge 2107 on the substrate 3 and the orthographic projection of the eighth edge 2108 on the substrate 3 along the second direction Y is the fourth width d.

[0137] Please see Figure 3 The aforementioned sixth edge 2106 and eighth edge 2108 are arranged along the first direction X.

[0138] The aforementioned film layer used to constitute sub-pixel 101 is a light-emitting device, comprising a first electrode layer, a light-emitting functional layer, and a second electrode layer stacked sequentially. The light-emitting color of the light-emitting device can be changed by adjusting the material of the light-emitting functional layer.

[0139] In some embodiments, the display panel 10 further includes a pixel definition layer located between the substrate 3 and the isolation structure 2, and a first electrode layer located between the pixel definition layer and the substrate 3. The pixel definition layer has pixel openings, and the light-emitting functional layer passes through the pixel openings and connects to the first electrode layer.

[0140] The display panel 10 also has at least one of the following film layer structures on the side of the light-emitting device facing away from the substrate 3: an encapsulation layer, a planarization layer, an organic encapsulation film layer, an inorganic encapsulation film layer, a touch layer, an organic adhesive layer, and a cover plate.

[0141] Taking the planarization layer as an example, the material of the planarization layer may include at least one of organic materials and inorganic materials. For example, organic polymers (such as polyimide, acrylic resin, etc.) or inorganic materials (such as silicon oxide, silicon nitride, etc.).

[0142] The planarization layer made of organic materials can be prepared using techniques such as IJP (Ink-Jet Printing). Part of the planarization layer can flow into the aforementioned isolation opening 201, and by filling the isolation opening 201, it improves the flatness of the display panel 10, while also providing some protection to the related film layers located below it.

[0143] It is understood that the display panel 10 provided in this application embodiment can increase the opening size of at least some of the isolation openings 201 by adjusting the width of the isolation structure 2 between adjacent sub-pixels 101, without affecting the normal use of other devices on the display panel 10, and ultimately improve the aperture ratio of the display panel 10. This technical solution can improve the display effect of the display panel 10 and enhance its performance.

[0144] Secondly, this embodiment also provides a display panel 10, please refer to... Figures 1-7 .

[0145] Specifically, the display panel 10 includes a plurality of repeating pixel units 1 arranged in an array, and each pixel unit 1 includes a plurality of sub-pixels 101. The display panel 10 also includes an isolation structure 2, which encloses a plurality of isolation openings 201, and a sub-pixel 101 is located in one isolation opening 201. At this time, any two adjacent sub-pixels 101 can be separated by the isolation structure 2 with the isolation opening 201. Any pixel unit 1 includes a plurality of sub-pixels 101, and at least some pixel units 1 include a first sub-pixel R, a second sub-pixel G, and a third sub-pixel B that are adjacent to each other. For the same pixel unit 1, the minimum width of the isolation structure 2 between the first sub-pixel R and the second sub-pixel G is a first width a, the minimum width of the isolation structure 2 between the first sub-pixel R and the third sub-pixel B is a third width c, and the minimum width of the isolation structure 2 between the second sub-pixel G and the third sub-pixel B is a fourth width d; the first width a is greater than the third width c, and / or, the first width a is greater than the fourth width d.

[0146] It should be noted that the aforementioned width refers to the distance between two adjacent isolation openings 201 at corresponding positions of the isolation structure 2. Since the opening shape of the isolation openings 201 in the thickness direction of the display panel 10 may be different, such as circular, elliptical, rectangular, or strip-shaped, the spacing between two adjacent isolation openings 201 may be within a certain range. To better define the aforementioned first width a, third width c, and fourth width d, we define each of these widths as the minimum spacing between two adjacent isolation openings 201, that is, the minimum width value of the isolation structure 2 located between two adjacent isolation openings 201.

[0147] In the display panel 10 provided in this application embodiment, each sub-pixel 101 is separated by an isolation structure 2 having an isolation opening 201. By adjusting the size of the isolation opening 201 used to accommodate and separate the sub-pixels 101, such that the third width c is smaller than the first width a and the fourth width d is smaller than the first width a, the spacing between two adjacent pixel units 1 can be effectively reduced, and the opening size of the isolation opening 201 corresponding to the first sub-pixel R located at the edge of the pixel unit 1 is increased in this direction, thereby improving the aperture ratio of the isolation opening 201, achieving the purpose of improving the display effect of the display panel 10 and improving the performance of the display panel 10.

[0148] It should be noted that when differentiating the width of the isolation structure 2 at different locations, it is necessary to ensure that the above-mentioned differential design does not affect the normal function of other film layers and devices of the display panel 10.

[0149] For example, if shortening the first width a would affect other components of the display panel 10, then the third width c and the fourth width d should be reduced, provided that the first width a meets the existing design requirements, in order to shorten the width of the isolation structure 2 between the adjacent first sub-pixel R and the third sub-pixel B, and the width of the isolation structure 2 between the adjacent second sub-pixel G and the third sub-pixel B, thereby increasing the aperture size of the relevant sub-pixel 101 and increasing the aperture ratio of the display panel 10.

[0150] Please see Figure 2 and Figure 3 For the same pixel unit 1, the first sub-pixel R and the second sub-pixel G are located on the same side of the third sub-pixel B. The first sub-pixel R and the second sub-pixel G are arranged along the first direction X, and the third sub-pixel B is located on the second direction Y side of either the first sub-pixel R or the second sub-pixel G. The first direction X and the second direction Y are orthogonal.

[0151] Specifically, the first width a is the width of the isolation structure 2 in the first direction X, and the third width c and the fourth width d are the widths of the isolation structure 2 in the second direction Y.

[0152] Along the second direction Y, at least one of the first sub-pixel R and the second sub-pixel G overlaps with at least a portion of the third sub-pixel B.

[0153] In some embodiments, at least a portion of the sub-pixels 101 may be a strip or rectangular structure extending along the first direction X. (See also...) Figure 3 In the figure, each sub-pixel 101 is a rounded rectangle or a similar rounded rectangle structure extending along the first direction X. Correspondingly, the opening shape of the isolation opening 201 on the isolation structure 2 can also be a rounded rectangle or a similar rounded rectangle structure that matches the shape of each sub-pixel 101.

[0154] Please see Figure 3 In the first direction X, the length of the first sub-pixel R is the first length, the length of the second sub-pixel G is the second length, and the length of the third sub-pixel B is the third length. The first length is less than the second length.

[0155] The third length is greater than either the first or the second length, and the sum of the first and the second lengths is less than the third length.

[0156] The first sub-pixel R, the second sub-pixel G, and the third sub-pixel B all emit different colors.

[0157] Please see Figure 3 In the diagram, the first sub-pixel R emits red light, the second sub-pixel G emits green light, and the third sub-pixel B emits blue light. Within the same pixel unit 1, the red and green pixels are arranged along the first direction X, and the blue pixel is located to the right of the red and green pixels.

[0158] The luminous area of ​​the first sub-pixel R is smaller than that of the third sub-pixel B, and the luminous area of ​​the second sub-pixel G is smaller than that of the third sub-pixel B. It can also be observed that the sum of the luminous areas of the first sub-pixel R and the second sub-pixel G is smaller than the luminous area of ​​the third sub-pixel B.

[0159] For two adjacent pixel units 1 along the first direction X, the first sub-pixel R in one pixel unit 1 is adjacent to the second sub-pixel G in the other pixel unit 1, and the minimum width of the isolation structure 2 between them is the second width b, and the first width a is greater than the second width b.

[0160] By adjusting the size of the isolation opening 201 used to accommodate and separate the aforementioned sub-pixels 101, so that the second width b is smaller than the first width a, the spacing between two adjacent pixel units 1 can be effectively reduced, and the opening size of the isolation opening 201 corresponding to the first sub-pixel R located at the edge of the pixel unit 1 can be increased in that direction, thereby improving the aperture ratio of the isolation opening 201, and achieving the purpose of improving the display effect of the display panel 10 and improving the performance of the display panel 10.

[0161] It should be noted that when differentiating the width of the isolation structure 2 at different locations, it is necessary to ensure that the above-mentioned differential design does not affect the normal function of other film layers and devices of the display panel 10.

[0162] For example, if shortening the first width a would affect other components of the display panel 10, then the second width b should be reduced to increase the opening size of the isolation opening 201 corresponding to the first sub-pixel R, thereby increasing the aperture ratio of the display panel 10, provided that the first width a meets the existing design requirements.

[0163] In some embodiments, two adjacent pixel units 1 are located in the same column and arranged along the first direction X. Please refer to [link / reference]. Figure 2 Different pixel units 1 can be powered by different array circuits. In the first direction X, pixel units 1 located at different positions are different pixel units 1.

[0164] In some embodiments, the first sub-pixel R and the second sub-pixel G located in the same pixel unit 1 are arranged along the first direction X. See also Figure 2 At this time, all the first sub-pixels R and the second sub-pixels G are arranged in a repeating pattern along the first direction X, and the width of the isolation structure 2 between the first sub-pixels R and the second sub-pixels G at different positions is different.

[0165] For details, please refer to Figure 2 and Figure 3 The first sub-pixel R, the second sub-pixel G, and the third sub-pixel B emit different colors.

[0166] The emission color of the first sub-pixel R can be defined as red, the emission color of the second sub-pixel G as green, and the emission color of the third sub-pixel B as blue.

[0167] Please see Figure 2 and Figure 3 The luminous area of ​​the first sub-pixel R is smaller than the luminous area of ​​the second sub-pixel G. The luminous areas of both the first sub-pixel R and the second sub-pixel G are smaller than the luminous area of ​​the third sub-pixel B.

[0168] Please see Figures 4-7 The isolation structure 2 in the figure has multiple isolation openings 201, which are used to separate different sub-pixels 101.

[0169] The display panel 10 also includes a substrate 3, and the isolation structure 2 is located on one side of the substrate 3.

[0170] The support portion 22 located between two adjacent isolation openings 201 can have a structure that is trapezoidal, rectangular, or inverted trapezoidal. In this embodiment, the support portion 22 is an inverted trapezoidal structure.

[0171] The crown 21 is located at the end of the support 22 facing away from the substrate 3. The structure of the crown 21 located between two adjacent isolation openings 201 can be trapezoidal or rectangular.

[0172] It should be noted that the support portion 22 can be a single-layer structure or a multi-layer structure. When the support portion 22 is a multi-layer structure, it can be configured to include at least two stacked sub-support portions. The orthographic projection of the sub-support portion farther from the substrate 3 onto the substrate 3 is located within the orthographic projection range of the sub-support portion closer to the substrate 3 onto the substrate 3.

[0173] The sidewall of the sub-support portion farther from the substrate 3 facing the isolation opening 201 is offset towards the side farther from the isolation opening 201, relative to the sidewall of the sub-support portion closer to the substrate 3, so that the cross-sectional sidewall of the isolation structure 2 presents a roof-like shape.

[0174] Of course, in other similar embodiments, the dimensional and projection relationships between the sequentially stacked sub-supports and crown 21 can also be adaptively adjusted according to actual processing needs.

[0177] Please see Figure 6In the figure, two spaced-apart openings 201 are filled with a first color sub-pixel R and a third color sub-pixel B, respectively, and the two sub-pixels 101 belong to the same pixel unit 1.

[0179] Please see Figure 3 The aforementioned sixth edge 2106 and eighth edge 2108 are arranged along the first direction X.

[0180] The aforementioned film layer used to constitute sub-pixel 101 is a light-emitting device, comprising a first electrode layer, a light-emitting functional layer, and a second electrode layer stacked sequentially.
