[0002] Currently, display panels (such as liquid crystal display panels) have spacers of different heights between a first substrate and a second substrate to control the uniformity of the spacing between the first and second substrates. These spacers of different heights are formed on the same side substrate (e.g.,...). Figure 1 and Figure 2 As shown in 150' and 160', the process required to form spacers of different heights is complex, and there are problems such as difficulty in reducing costs and difficulty in increasing the spacing between the first substrate and the second substrate to obtain a spacing that meets product requirements.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0032] Currently, due to the need for a load-bearing process to form spacers of different heights, there are technical problems with display panels, such as difficulty in reducing manufacturing costs and difficulty in increasing the spacing between the first and second substrates.

[0033] Please see Figures 3 to 5 The present invention provides a display panel 100, comprising:

[0034] First substrate 110;

[0035] The second substrate 120 is disposed opposite to the first substrate 110;

[0036] The first color resist layer 130 is located on the side of the first substrate 110 close to the second substrate 120, and the first color resist layer 130 includes a first color resist 131 and a second color resist 132.

[0037] The second color resist layer 140 is located on the side of the second substrate 120 close to the first substrate 110, and the second color resist layer 140 includes a third color resist layer 141.

[0038] A first spacer 150 is located between the first substrate 110 and the second substrate 120. The first spacer 150 includes a first unit 151 located on the side of the first substrate 110 near the second substrate 120.

[0039] The second spacer 160 is located between the first substrate 110 and the second substrate 120. The second spacer 160 includes a second unit 161. In the direction from the first substrate 110 to the second substrate 120, the height of the first spacer 150 is greater than the height of the second spacer 160.

[0040] The first unit 151 includes a first color resist portion 151a, the material of which is the same as that of the first color resist 131 and the second color resist 132. The second unit 161 includes a second color resist portion 161a, the material of which is the same as that of the first color resist 131, the second color resist 132 and the third color resist 141.

[0041] In this embodiment of the invention, the first color resist portion 151a in the first spacer 150 and the second color resist portion 161a in the second spacer 160 use the same material as both the first color resist 131, the second color resist 132 and the third color resist 141. The first spacer 150 and the second spacer 160 are formed at least partially simultaneously with the first color resist layer 130 and / or the second color resist layer 140, which helps to simplify the manufacturing process, reduce the manufacturing cost, and facilitate increasing the spacing between the first substrate 110 and the second substrate 120.

[0042] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0043] Please see Figures 3 to 5 In this embodiment, in the direction from the first substrate 110 to the second substrate 120, the height of the first spacer 150 is greater than the height of the second spacer 160, thereby forming a step difference, which is beneficial to improving the performance of the display panel 100, such as buffering, thereby improving the product quality of the display panel 100.

[0044] In this embodiment, the colors of the first color resist 131, the second color resist 132, and the third color resist 141 are different from each other, and the first color resist 131, the second color resist 132, and the third color resist 141 are respectively selected from one of red color resist, green color resist, and blue color resist.

[0045] In some embodiments, the display panel 100 further includes a liquid crystal layer located between the first substrate 110 and the second substrate 120. Increasing the spacing between the first substrate 110 and the second substrate 120 helps to increase the thickness of the liquid crystal layer, thereby facilitating matching with the performance of the liquid crystal material in the liquid crystal layer and improving the product performance of the display panel 100.

[0046] In some embodiments, the first unit 151 is located on the side of the first substrate 110 near the second substrate 120, that is, the first unit 151 and the first color resist layer 130 are located between the liquid crystal layer and the first substrate 110. The material of the first color resist portion 151a is the same as the material of one of the first color resist 131 and the second color resist 132, so that the first color resist portion 151a and the first color resist layer 130 can be formed in the same process. Since the material of the first color resist portion 151a is a color resist material, it is easy to control the height of the first color resist portion 151a in the direction from the first substrate 110 to the second substrate 120. This simplifies the process and facilitates obtaining a first spacer 150 with a higher height in the direction from the first substrate 110 to the second substrate 120, increasing the spacing between the first substrate 110 and the second substrate 120, and improving the product performance of the display panel 100.

[0047] In some embodiments, the height of the first color resist portion 151a is the maximum spacing between the opposite sides of the first color resist portion 151a in the direction from the first substrate 110 to the second substrate 120.

[0048] Please see Figures 3 to 5 In some embodiments, the first unit 151 further includes a third color resist portion 151b, which is located on the side of the first color resist portion 151a close to the second substrate 120. The material of the third color resist portion 141 is the same as that of one of the first color resist portion 131 and the second color resist portion 132, and the material of the first color resist portion 151a is different from that of the third color resist portion 151b. In the direction from the first substrate 110 to the second substrate 120, the first color resist portion 151a and the second color resist portion 161a are stacked. The materials of the first color resist portion 151a and the second color resist portion 161a are the same as the materials of the first color resist 131 and the second color resist 132. They can be formed in the same process as the first color resist 131 and the second color resist 132. The stacking of the first color resist portion 151a and the second color resist portion 161a is beneficial to obtaining the first spacer 150 with a higher height in the direction from the first substrate 110 to the second substrate 120, further increasing the spacing between the first substrate 110 and the second substrate 120, and improving the product performance of the display panel 100.

[0049] In some embodiments, the height of the third color resist portion 151b is the maximum spacing between the opposite sides of the third color resist portion 151b in the direction from the first substrate 110 to the second substrate 120.

[0050] In some embodiments, the first unit 151 may have only the first color resist portion 151a made of the same material as one of the first color resist 131 and the second color resist 132; or, the first unit 151 may have only the first color resist portion 151a and the third color resist 141 made of the same material as the first color resist 131 and the second color resist 132, and the material of the first color resist portion 151a may be different from the material of the third color resist portion 151b. Compared to providing more color resist portions with the same color resist material as the first color resist layer 130, providing only one color resist portion or two stacked color resist portions not only reduces the process difficulty of forming the first unit 151, but also helps to reduce the critical dimension (CD) of the first unit 151, reduce the area of ​​the orthographic projection of the first spacer 150 in the plane of the first substrate 110, and improve the display effect of the display panel 100.

[0051] Please see Figures 4 to 5 In some embodiments, the first spacer 150 further includes a third unit 152 located on the side of the second substrate 120 near the first substrate 110. The third unit 152 is disposed corresponding to the first unit 151. The third unit 152 includes a fourth color resist portion 152a, and the material of the fourth color resist portion 152a is the same as that of the third color resist 141. The third unit 152 and the second color resist layer 140 are located between the second substrate 120 and the liquid crystal layer. The material of the fourth color resist portion 152a is the same as that of the third color resist 141, so that the fourth color resist portion 152a and the second color resist layer 140 can be formed in the same process. Since the material of the fourth color resist portion 152a is the same as that of the third color resist 141, both being color resist materials, it is easy to control the height of the fourth color resist portion 152a in the direction from the first substrate 110 to the second substrate 120. Meanwhile, the third unit 152 is correspondingly disposed to the first unit 151, that is, one first spacer 150 is composed of one third unit 152 and one first unit 151. The third unit 152 is correspondingly disposed to the first unit 151, and the orthographic projection of the third unit 152 in the plane of the first substrate 110 at least partially overlaps with the orthographic projection of the first unit 151 in the plane of the first substrate 110. The arrangement of the first color resist portion 151a, the third color resist portion 151b and the fourth color resist portion 152a facilitates the control of the height of the first spacer 150 in the direction from the first substrate 110 to the second substrate 120, which is beneficial to obtaining a first spacer 150 with a greater height and improving the product performance of the display panel 100.

[0052] In some embodiments, the height of the fourth color resist portion 152a is the maximum spacing between the opposite sides of the fourth color resist portion 152a in the direction from the first substrate 110 to the second substrate 120.

[0053] Please see Figures 3 to 5 In some embodiments, the distance between the side of the first unit 151 near the second substrate 120 and the plane where the second substrate 120 is located is less than the distance between the side of the first color resist layer 130 near the second substrate 120 and the plane where the second substrate 120 is located, so as to realize the supporting function of the first spacer 150.

[0054] Please see Figures 3 to 4 In some embodiments, the second unit 161 is located on the side of the second substrate 120 near the first substrate 110, that is, the second unit 161 and the second color resist layer 140 are located between the liquid crystal layer and the second substrate 120. The material of the second color resist portion 161a is the same as the material of the third color resist 141, so that the second color resist portion 161a and the second color resist layer 140 can be formed in the same process. Since the material of the second color resist portion 161a is a color resist material, it is easy to control the height of the second color resist portion 161a in the direction from the first substrate 110 to the second substrate 120. This simplifies the process and facilitates control of the height difference between the second spacer 160 and the first spacer 150, thereby improving the product performance of the display panel 100.

[0055] In some embodiments, the height of the second color resist portion 161a is the maximum spacing between the opposite sides of the second color resist portion 161a in the direction from the first substrate 110 to the second substrate 120.

[0056] Please see Figure 5 In some embodiments, the second unit 161 is located on the side of the first substrate 110 closer to the second substrate 120, that is, the second unit 161 and the first color resist layer 130 are located between the liquid crystal layer and the first substrate 110. The material of the second color resist portion 161a is the same as the material of one of the first color resist 131 and the second color resist 132, so that the second color resist portion 161a and the first color resist layer 130 can be formed in the same process. Since the material of the second color resist portion 161a is a color resist material, it is easy to control the height of the second color resist portion 161a in the direction from the first substrate 110 to the second substrate 120. This simplifies the process and facilitates control of the height difference between the second spacer 160 and the first spacer 150, thereby improving the product performance of the display panel 100.

[0057] Please see Figures 3 to 4 In some embodiments, when the second unit 161 is located on the side of the second substrate 120 close to the first substrate 110, the height of the second color resist portion 161a and the height of the fourth color resist portion 152a can be the same in the direction from the first substrate 110 to the second substrate 120. In this case, the second color resist portion 161a and the fourth color resist portion 152a have the same material and height, which is beneficial for them to be formed together in the same process, reducing process costs. It is understood that, in the direction from the first substrate 110 to the second substrate 120, the second color resist portion 161a and the fourth color resist portion 152a have the same height, indicating that in the direction from the first substrate 110 to the second substrate 120, the ratio of the height of the second color resist portion 161a to the height of the fourth color resist portion 152a is 0.95:1 to 1:1.05, for example, it can be 0.96:1, 0.97:1, 0.98:1, 0.99:1, 1:1, 1:1.01, 1:1.02, 1:1.03, 1:1.04, etc.

[0058] Please see Figure 5 In some embodiments, when the second unit 161 is located on the side of the first substrate 110 close to the first substrate 110, the height of the second color resist portion 161a and the height of the first color resist portion 151a can be the same in the direction from the first substrate 110 to the second substrate 120, or the height of the second color resist portion 161a and the height of the third color resist portion 151b can be the same. This is beneficial for the second color resist portion 161a to be formed together with the first color resist portion 151a or the third color resist portion 151b in the same process, thereby reducing process costs.

[0059] Please see Figures 4 to 5In some embodiments, the second spacer 160 further includes a fourth unit 162, which is correspondingly disposed with the second unit 161. When the second unit 161 is located on the side of the second substrate 120 closer to the first substrate 110, the fourth unit 162 is located on the side of the first substrate 110 closer to the second substrate 120; or, when the second unit 161 is located on the side of the first substrate 110 closer to the second substrate 120, the fourth unit 162 is located on the side of the second substrate 120 closer to the first substrate 110. The fourth unit 162 is correspondingly disposed with the second unit 161, that is, one second spacer 160 is composed of one fourth unit 162 and one second unit 161. The orthographic projection of the fourth unit 162 in the plane of the first substrate 110 at least partially overlaps with the orthographic projection of the second unit 161 in the plane of the first substrate 110. The fourth unit 162 allows for more flexible control of the height of the second spacer 160 in the direction from the first substrate 110 to the second substrate 120. This simplifies the manufacturing process and facilitates control of the height difference between the second spacer 160 and the first spacer 150, thereby improving the product performance of the display panel 100.

[0060] In some embodiments, the fourth unit 162 includes a fifth color resist portion 162a. When the fourth unit 162 is located on the side of the first substrate 110 close to the second substrate 120, the material of the fifth color resist portion 162a is the same as the material of one of the first color resist 131 and the second color resist 132. For example, the material of the fifth color resist portion 162a is the same as the material of the first color resist portion 151a, and the height of the fifth color resist portion 162a is the same as the height of the first color resist portion 151a in the direction from the first substrate 110 to the second substrate 120; or, the material of the fifth color resist portion 162a is the same as the material of the third color resist portion 151b, and the height of the fifth color resist portion 162a is the same as the height of the third color resist portion 151b in the direction from the first substrate 110 to the second substrate 120. By using the same material and height as the fifth color resist portion 162a and the first color resist portion 151a or the third color resist portion 151b, it is advantageous for the fifth color resist portion 162a and the first color resist portion 151a or the third color resist portion 151b to be formed using the same manufacturing process, thereby reducing manufacturing costs. It is understood that if the fifth color resist portion 162a and the first color resist portion 151a have the same height in the direction from the first substrate 110 to the second substrate 120, it means that the ratio of the height of the fifth color resist portion 162a to the height of the first color resist portion 151a in the direction from the first substrate 110 to the second substrate 120 is 0.95:1 to 1:1.05, for example, it can be 0.96:1, 0.97:1, 0.98:1, 0.99:1, 1:1, 1:1.01, 1:1.02, 1:1.03, 1:1.04, etc. Similarly, in the direction from the first substrate 110 to the second substrate 120, the fifth color resist portion 162a and the third color resist portion 151b have the same height, indicating that in the direction from the first substrate 110 to the second substrate 120, the ratio of the height of the fifth color resist portion 162a to the height of the third color resist portion 151b is 0.95:1 to 1:1.05, for example, it can be 0.96:1, 0.97:1, 0.98:1, 0.99:1, 1:1, 1:1.01, 1:1.02, 1:1.03, 1:1.04, etc.

[0061] In some embodiments, the height of the fifth color resist portion 162a is the maximum spacing between the opposite sides of the fifth color resist portion 162a in the direction from the first substrate 110 to the second substrate 120.

[0062] In some embodiments, when the fourth unit 162 is located on the side of the second substrate 120 close to the first substrate 110, the material of the fifth color resist portion 162a is the same as the material of the third color resist 141, so that the fifth color resist portion 162a and the second color resist layer 140 are formed in the same process. Since the material of the fifth color resist portion 162a is a color resist material, it is easy to control the height of the fifth color resist portion 162a in the direction from the first substrate 110 to the second substrate 120. This simplifies the manufacturing process and facilitates control of the step difference between the height of the second spacer 160 and the height of the first spacer 150, thereby improving the product performance of the display panel 100.

[0063] Please see Figure 5 In some embodiments, the height of the fifth color resist portion 162a is the same as the height of the fourth color resist portion 152a in the direction from the first substrate 110 to the second substrate 120. This facilitates their simultaneous formation in the same process, reducing process costs. It is understood that the fact that the fifth color resist portion 162a and the fourth color resist portion 152a have the same height in the direction from the first substrate 110 to the second substrate 120 indicates that the ratio of the height of the fifth color resist portion 162a to the height of the fourth color resist portion 152a in the direction from the first substrate 110 to the second substrate 120 is 0.95:1 to 1:1.05. For example, it can be 0.96:1, 0.97:1, 0.98:1, 0.99:1, 1:1, 1:1.01, 1:1.02, 1:1.03, 1:1.04, etc.

[0064] Please see Figures 3 to 5In some embodiments, the display panel 100 further includes a planarization layer 170 located on the side of the second substrate 120 near the first substrate 110, the planarization layer 170 being located on the side of the second color resist layer 140 away from the second substrate 120. When the second color resist portion 161a or the fifth color resist portion 162a is located on the side of the second substrate 120 near the first substrate 110, the planarization layer 170 covers the second color resist layer 140, the second color resist portion 161a, or the fifth color resist portion 162a; when the fourth color resist portion 152a is located on the side of the second substrate 120 near the first substrate 110, the planarization layer 170 covers the fourth color resist portion 152a. The planarization layer 170 is made of an organic transparent material with leveling properties, so as to make the side of the second substrate 120 near the first substrate 110 have a relatively flat surface. Meanwhile, due to the leveling effect of the material of the planarization layer 170, compared to setting multiple stacked color resist portions on one side of the second substrate 120, setting a single second color resist portion 161a, the fourth color resist portion 152a, or the fifth color resist portion 162a is more advantageous in reducing the critical dimensions of the second color resist portion 161a, the fourth color resist portion 152a, or the fifth color resist portion 162a, thereby reducing the area of ​​the orthographic projection of the first spacer 150 and / or the second spacer 160 in the plane of the first substrate 110 and improving the display effect of the display panel 100.

[0065] In some embodiments, when the second unit 161 is located on the side of the second substrate 120 close to the first substrate 110, the planarization layer 170 further includes a first planarization portion located within the second unit 161, and the second unit 161 is composed of the second color resist portion 161a and the first planarization portion.
