[0050] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0052] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the ordinary meanings as understood by those of ordinary skill in the art to which the present disclosure pertains. The "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "comprising" or "including" mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The terms "connected" or "coupled" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right" and the like are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0053] As used herein, "parallel" and "perpendicular" include the stated circumstances and circumstances similar to the stated circumstances, where the range of the similar circumstances is within an acceptable deviation range, which is determined by those of ordinary skill in the art considering the measurements being discussed and the errors associated with the measurements of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5° deviation; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5° deviation.

[0054] It should be understood that when a layer or element is referred to as being on another layer or substrate, it may be that the layer or element is directly on the other layer or substrate, or there may be an intermediate layer between the layer or element and the other layer or substrate.

[0055] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and regions is exaggerated for clarity. Thus, variations in the shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Accordingly, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but include shape deviations caused, for example, by manufacturing. Thus, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shape of the regions of the device and are not intended to limit the scope of the exemplary embodiments.

[0056] In the related art, as Figure 1 and Figure 2As shown in the figure, the LCD display panel includes an array substrate 1, a color filter substrate 2, and a liquid crystal layer 3 located between the array substrate 1 and the color filter substrate 2. The array substrate 1 includes a first substrate 11, and a plurality of gate lines 12 and a plurality of data lines 13 disposed on the first substrate 11. Among them, the plurality of gate lines 12 and the plurality of data lines 13 intersect to define a plurality of pixel regions P. The color filter substrate 2 includes a second substrate 21, a color filter layer 22 and a black matrix 23 located on one side of the second substrate 21. Among them, the color filter layer 22 and the black matrix 23 are stacked. The color filter layer 22 includes a plurality of color filter portions 220, and the color filter portions 220 correspond to the pixel regions P one by one.

[0057] Among them, the LCD display panel can be used in a projector. After the backlight emitted by the backlight module in the projector passes through the LCD display panel, it is projected onto the screen to form an image.

[0058] In the display panel as shown in Figure 1 the figure, the data line 13 and the black matrix 23 act as a light-shielding layer to shield the splicing portion of adjacent color filter portions 220. When the display panel is used in a projector, a part of the black matrix 23 can be removed. For example, Figure 2 the display panel shown in Figure 1 the figure is based on the display panel shown in Figure 1 the figure, removing the black matrix 23 extending along the data line 13 direction, and only retaining the black matrix 23 extending along the gate line 12 direction. Compared with Figure 2The display panel shown can improve the pixel aperture ratio, but at the same time, it is prone to problems such as color mixing and moiré. Among them, the color mixing problem refers to the phenomenon of mixing or crossing between color filter parts 220 of different colors. For example, when the color filter part 220 enters the adjacent color filter parts 220 of different colors, it will cause the color mixing problem. The moiré problem mainly refers to the obvious grid-like and dot-like interference that appears when the projector projects onto the screen, which destroys the display effect of the projection image. For example, when the second filter part 222 that transmits green light enters the first filter part 221 that transmits red light and the third filter part 223 that transmits blue light, it will cause the uneven brightness of the light transmitted by the first filter part 221 and the third filter part 223. After being magnified by the projector, the light transmitted by the first filter part 221 and the third filter part 223 will become thicker, which macroscopically shows the moiré problem. Another example is that the appearance of gaps between adjacent color filter parts 220 will also cause the moiré problem. The above problems will seriously affect the image quality of the projection image of the LCD projector. In addition, during the process of preparing the color filter part 220, due to process fluctuations, the width of the color filter part 220 fluctuates within a certain range. At the same time, when the prepared color film substrate 2 and the array substrate 1 are aligned, due to process fluctuations, the alignment accuracy will also fluctuate within a certain range. This will cause a misalignment at the splicing position of the data line 13 and the adjacent two color filter parts 220, resulting in the data line 13 failing to play the corresponding light-shielding role. Therefore, Figure 2 During the preparation process of the display panel shown, high precision is required for the width accuracy and alignment accuracy of the color filter part 220. Therefore, the process difficulty is relatively high.

[0059] In order to at least alleviate or solve one of the above-mentioned technical problems, the present disclosure proposes a display panel, a display device, and a color film substrate.

[0060] In a first aspect, the present disclosure provides a display panel. In some embodiments, as Figure 3 and Figure 4 shown, a display panel provided by the present disclosure includes: a color film substrate 2 and an array substrate 1 arranged opposite to each other.

[0061] Among them, the array substrate 1 includes a first substrate 11 and a plurality of gate lines 12 and a plurality of data lines 13 disposed on the first substrate 11. The gate lines 12 and the data lines 13 are arranged crosswise to define a plurality of pixel regions P. The color film substrate 2 includes a second substrate 21 and a color film layer 22 on one side of the second substrate 21. The color film layer 22 includes a plurality of color filter parts 220, and the color filter parts 220 correspond to the pixel regions P one by one.

[0062] Among them, the multiple color filter portions 220 include multiple first filter portions 221 and multiple second filter portions 222. The light transmittance of the first filter portion 221 is less than that of the second filter portion 222. The orthographic projection of the first filter portion 221 and the data line 13 on the second substrate 21 has a first overlapping region. The orthographic projection of the second filter portion 222 and the data line 13 on the second substrate 21 has a second overlapping region, and the width H2 of the second overlapping region is less than the width H1 of the first overlapping region, or the orthographic projection of the second filter portion 222 and the data line 13 on the second substrate 21 has no overlap.

[0063] It should be noted that the width in the embodiments of the present disclosure refers to the width in the extending direction of the gate line 12. For example, the width H2 of the second overlapping region being less than the width H1 of the first overlapping region means that the width H2 of the second overlapping region in the extending direction of the gate line 12 is less than the width H1 of the first overlapping region in the extending direction of the gate line 12.

[0064] Among them, in Figure 3 In the illustrated embodiment, the orthographic projection of the first filter portion 221 and the data line 13 on the second substrate 21 has a first overlapping region, the orthographic projection of the second filter portion 222 and the data line 13 on the second substrate 21 has a second overlapping region, and the width H2 of the second overlapping region is less than the width H1 of the first overlapping region.

[0065] In Figure 4 In the illustrated embodiment, the orthographic projection of the first filter portion 221 and the data line 13 on the second substrate 21 has a first overlapping region, and the orthographic projection of the second filter portion 222 and the data line 13 on the second substrate 21 has no overlap.

[0066] In the embodiments of the present disclosure, the orthographic projection of the first filter portion 221 and the data line 13 on the second substrate 21 has a first overlapping region. At the same time, the orthographic projection of the second filter portion 222 and the data line 13 on the second substrate 21 has a second overlapping region and the width of the second overlapping region is less than that of the first overlapping region, or the orthographic projection of the second filter portion 222 and the data line 13 on the second substrate 21 has no overlap, which can prevent the light that should be incident on the second filter portion 222 with a higher light transmittance from being incident on the first filter portion 221 with a lower light transmittance, thereby avoiding problems such as lattice points and color mixing.

[0067] In the embodiments of the present disclosure, optionally, there may be a gap between two adjacent color filter portions 220. Optionally, there may be a mixed overlap between two adjacent color filter portions 220. For example, a part of the first filter portion 221 extends out and overlaps with the second filter portion 222.

[0068] In some embodiments, such as Figure 5 and Figure 6As shown, in addition to including a plurality of first filter portions 221 and a plurality of second filter portions 222, the plurality of color filter portions 220 further include a plurality of third filter portions 223. Moreover, the light transmittance of the first filter portion 221 is greater than that of the third filter portion 223. There is a third overlapping region between the positive projection of the third filter portion 223 and the data line 13 on the second substrate 21, and the width H3 of the third overlapping region is equal to the width H1 of the first overlapping region.

[0069] Moreover, from the fact that the light transmittance of the first filter portion 221 is greater than that of the third filter portion 223 and the light transmittance of the first filter portion 221 is less than that of the second filter portion 222, it can be known that: the light transmittance of the third filter portion 223 is less than that of the second filter portion 222. Therefore, there is a third overlapping region between the positive projection of the third filter portion 223 and the data line 13 on the second substrate 21. And, there is a fourth overlapping region between the positive projection of the second filter portion 222 and the data line 13 on the second substrate 21 and the width H4 of the fourth overlapping region is less than the width H3 of the third overlapping region, or, there is no overlap between the positive projection of the second filter portion 222 and the data line 13 on the second substrate 21. Among them, Figure 5 in the illustrated embodiment, there is a fourth overlapping region between the positive projection of the second filter portion 222 and the data line 13 adjacent to the third filter portion 223 on the second substrate 21 and the width H4 of the fourth overlapping region is less than the width H3 of the third overlapping region, Figure 6 in the illustrated embodiment, there is also no overlap between the positive projection of the second filter portion 222 and the data line 13 adjacent to the third filter portion 223 on the second substrate 21.

[0070] It should be noted that in the embodiments of the present disclosure, the data line 13 always refers to the data line corresponding to the splicing position of two adjacent color filter portions 220. For example, there is a first overlapping region between the positive projection of the first filter portion 221 and the data line 13 on the second substrate 21, and there is a second overlapping region between the positive projection of the second filter portion 222 and the data line 13 on the second substrate 21. The data line 13 therein refers to the data line corresponding to the splicing position of the first filter portion 221 and the second filter portion 222. There is a third overlapping region between the positive projection of the third filter portion 223 and the data line 13 on the second substrate 21, and there is a fourth overlapping region between the positive projection of the second filter portion 222 and the data line 13 on the second substrate 21. The data line 13 therein refers to the data line corresponding to the splicing position of the third filter portion 223 and the second filter portion 222.

[0071] The embodiments of the present disclosure can prevent the second light filtering portion 222 with a relatively high light transmittance from entering the first light filtering portion 221 with a relatively low light transmittance, and prevent the second light filtering portion 222 with a relatively high light transmittance from entering the third light filtering portion 223 with a relatively low light transmittance, thereby avoiding problems such as grid points and color mixing. At the same time, by setting the width of the third overlapping region equal to the width of the first overlapping region, the uniformity of the brightness of the transmitted light of the first light filtering portion 221, the second light filtering portion 222, and the third light filtering portion 223 can also be ensured.

[0072] In some embodiments, as Figure 7 shown, the first light filtering portion 221 and the second light filtering portion 222 are respectively disposed on opposite sides of the third light filtering portion 223 along the extending direction of the gate line 12, and the positive projection of any one of the first light filtering portion 221 and the second light filtering portion 222 on the second substrate 21 overlaps with the third light filtering portion 223.

[0073] In some embodiments, as Figure 7 shown, the first light filtering portion 221 includes a first main body portion 2211 and a first extending portion 2212 connected to the first main body portion 2211. The first main body portion 2211 is disposed opposite to the pixel region P corresponding to the first light filtering portion 221. The thickness D1 of the first main body portion 2211 is greater than the thickness D2 of the first extending portion 2212, and the thickness D3 of the third light filtering portion 223 is greater than the thickness D2 of the first extending portion 2212. The first extending portion 2212 is located on the side of the third light filtering portion 223 away from the second substrate 21.

[0074] The second light filtering portion 222 includes a second main body portion 2221 and a second extending portion 2222 connected to the second main body portion 2221. The second main body portion 2221 is disposed opposite to the pixel region P corresponding to the second light filtering portion 222. The thickness D4 of the second main body portion 2221 is greater than the thickness D5 of the second extending portion 2222. The thickness D3 of the third light filtering portion 223 is greater than the thickness D5 of the second extending portion 2222. The second extending portion 2222 is located on the side of the third light filtering portion 223 away from the second substrate 21.

[0075] In the embodiments of the present disclosure, the thickness D3 of the third light filtering portion 223 is greater than the thickness D5 of the second extending portion 2222, and the thickness D3 of the third light filtering portion 223 is greater than the thickness D2 of the first extending portion 2212. Therefore, the third light filtering portion 223 plays a major role, and can improve the brightness uniformity of the light transmitted by the third light filtering portion 223 with a relatively low light transmittance, and can also avoid the influence of the overlapping portion on the second light filtering portion 222 and the first light filtering portion 221, resulting in grid point and color mixing problems.

[0076] In the actual manufacturing process, the production sequence of the first light filtering part 221, the second light filtering part 222, and the third light filtering part 223 can be to first manufacture the third light filtering part 223 with a lower light transmittance and ensure the width of the third light filtering part 223, so that the third light filtering part 223 with a lower light transmittance preferentially occupies the spatial position in the color film layer 22. Then, the first light filtering part 221 and the second light filtering part 222 with higher light transmittance are manufactured. In this case, since the third light filtering part 223 has preferentially occupied the spatial position, the subsequently manufactured first light filtering part 221 and second light filtering part 222 with higher light transmittance will not enter the spatial position occupied by the third light filtering part 223 with a lower light transmittance, so that the brightness of the light transmitted by the third light filtering part 223 with a lower light transmittance will be more uniform during subsequent work processes, avoiding color mixing. On this basis, further, for the manufacture of the first light filtering part 221 and the second light filtering part 222, the first light filtering part 221 with a lower light transmittance can also be manufactured first, and then the second light filtering part 222 with a higher light transmittance can be manufactured. The reason is the same as above and will not be elaborated here.

[0077] Optionally, for the adjacent first light filtering part 221 and second light filtering part 222, the orthographic projections of the first light filtering part 221 and the second light filtering part 222 on the second substrate 21 can also overlap. And, further, a part of the second light filtering part 222 can extend to the side of the first light filtering part 221 away from the second substrate 21. It can also be understood that among two adjacent color filter parts 220, a part of the color filter part 220 with a higher light transmittance is located on the side of the color filter part 220 with a lower light transmittance away from the second substrate 21, so as to ensure the uniformity of the light output of the color filter part 220 with a lower light transmittance and avoid color mixing and lattice point problems.

[0078] In some embodiments, as Figure 7 shown, the overlapping width W1 of the orthographic projections of the first light filtering part 221 and the third light filtering part 223 on the second substrate 21 is less than or equal to 3 μm. For example, W1 can be 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, etc.

[0079] The overlapping width W2 of the orthographic projections of the second light filtering part 222 and the third light filtering part 223 on the second substrate 21 is less than or equal to 3 μm. For example, W2 can be 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, etc.

[0080] In the embodiments of the present disclosure, by making the orthographic projections of the first light filtering portion 221 and the third light filtering portion 223 on the second substrate 21 overlap, the moiré and color mixing problems caused by the gaps between the adjacent first light filtering portion 221 and the third light filtering portion 223 can be avoided. Similarly, by making the orthographic projections of the second light filtering portion 222 and the third light filtering portion 223 on the second substrate 21 overlap, the moiré and color mixing problems caused by the gaps between the adjacent second light filtering portion 222 and the third light filtering portion 223 can be avoided.

[0081] In some embodiments, the difference between the light transmittance of the second light filtering portion 222 and the light transmittance of the third light filtering portion 223 does not exceed 0.6 times the light transmittance of the second light filtering portion 222.

[0082] In the embodiments of the present disclosure, reducing the difference between the light transmittance of the second light filtering portion 222 and the light transmittance of the third light filtering portion 223, that is, reducing the difference between the light transmittances of the color filter portions 220 with the highest and the lowest light transmittances, can improve the moiré and color mixing problems. Further, making the difference between the light transmittance of the second light filtering portion 222 and the light transmittance of the third light filtering portion 223 not exceed 0.6 times the light transmittance of the second light filtering portion 222. For example, the difference between the light transmittance of the second light filtering portion 222 and the light transmittance of the third light filtering portion 223 can be 0.6 times, 0.5 times, 0.4 times, 0.3 times, 0.2 times, etc. of the light transmittance of the second light filtering portion 222, which can further significantly improve the moiré and color mixing problems. For example, in one example, the light transmittance GY of the second light filtering portion 222 is 75%, the light transmittance BY of the third light filtering portion 223 is 30% or more, and the difference between the light transmittance of the second light filtering portion 222 and the light transmittance of the third light filtering portion 223 does not exceed 45%, 45% = 0.6×75%. In this case, the moiré and color mixing problems of the transmitted light of the second light filtering portion 222 and the transmitted light of the third light filtering portion 223 in the display panel can be greatly improved.

[0083] Optionally, the light transmittance of the color filter portion 220 can be adjusted by methods such as changing the material, composition, and structure of the color filter portion 220.

[0084] Optionally, while reducing the difference between the light transmittance of the second light filtering portion 222 and the light transmittance of the third light filtering portion 223, the light transmittance of the first light filtering portion 221 and the light transmittance of the third light filtering portion 223 can be made as close as possible. For example, the light transmittance of the first light filtering portion 221 and the light transmittance of the third light filtering portion 223 can be made the same, or the difference between the light transmittance of the first light filtering portion 221 and the light transmittance of the third light filtering portion 223 does not exceed 5%. In the embodiments of the present disclosure, the moiré and color mixing problems of the transmitted light of the first light filtering portion 221 and the transmitted light of the third light filtering portion 223 can be improved.

[0085] In some embodiments, such asFigure 8 As shown, the color film substrate 2 further includes a black matrix 23 stacked with the color film layer 22. The black matrix 23 includes a plurality of first light-shielding bars 231 arranged along the extending direction of the data line 13 and second light-shielding bars 232 connected between two adjacent first light-shielding bars 231. Two adjacent first light-shielding bars 231 and two adjacent second light-shielding bars 232 define a light-passing hole.

[0086] A plurality of color filter portions 220 are arranged in multiple rows and columns. The multiple color filter portions 220 in the same row form a plurality of repeating units. Each repeating unit includes a second filter portion 222, a first filter portion 221, and a third filter portion 223 arranged in sequence, and the same repeating unit corresponds to the same light-passing hole. The orthographic projection of the second light-shielding bar 232 on the second substrate 21 overlaps with the orthographic projections of two adjacent repeating units on the second substrate 21. Specifically, among two adjacent repeating units, the second filter portion 222 of one repeating unit is adjacent to the third filter portion 223 of the other repeating unit. Therefore, it can also be understood that the orthographic projection of the second light-shielding bar 232 on the second substrate 21 overlaps with the orthographic projection of the second filter portion 222 in one repeating unit on the second substrate 21 and overlaps with the orthographic projection of the third filter portion 223 in the other repeating unit on the second substrate 21.

[0087] It can be understood that in the embodiments of the present disclosure, along the extending direction of the data line, no corresponding second light-shielding bar 232 is provided to block the splicing position between the adjacent first filter portion 221 and the third filter portion 223, and no corresponding second light-shielding bar 232 is provided to block the splicing position between the adjacent first filter portion 221 and the second filter portion 222. In the embodiments of the present disclosure, retaining the second light-shielding bar 232 whose orthographic projection on the second substrate 21 overlaps with the orthographic projections of the adjacent second filter portion 222 and the third filter portion 223 on the second substrate 21 can avoid the color mixing and lattice point problems of the adjacent second filter portion 222 and the third filter portion 223.

[0088] In some embodiments, as Figure 9 shown, a plurality of color filter portions 220 are arranged in multiple rows and columns. The color film substrate 2 further includes a black matrix 23 stacked with the color film layer 22. The black matrix 23 includes a plurality of first light-shielding bars 231 arranged along the extending direction of the data line 13, and there is a light-passing hole between two adjacent first light-shielding bars 231. The multiple color filter portions 220 in the same row correspond to the same light-passing hole.

[0089] In some embodiments, as Figure 9As shown, a plurality of data lines 13 are arranged at equal intervals in the extending direction of the gate lines 12. In this case, the width H5 of the first light filtering portion 221 is greater than the width H6 of the second light filtering portion 222, the width H7 of the third light filtering portion 223 is greater than the width H6 of the second light filtering portion 222, and the width H5 of the first light filtering portion 221 is equal to the width H7 of the third light filtering portion 223. Among them, the light transmittance of the first light filtering portion 221 is greater than that of the third light filtering portion 223, and the light transmittance of the first light filtering portion 221 is less than that of the second light filtering portion 222.

[0090] Embodiments of the present disclosure can achieve: the first light filtering portion 221 and the data line 13 have a first overlapping region in the positive projection on the second substrate 21, the second light filtering portion 222 and the data line 13 have a second overlapping region in the positive projection on the second substrate 21, the width H2 of the second overlapping region is less than the width H1 of the first overlapping region, or the second light filtering portion 222 and the data line 13 have no overlap in the positive projection on the second substrate 21; the third light filtering portion 223 and the data line 13 have a third overlapping region in the positive projection on the second substrate 21, and the width H3 of the third overlapping region is equal to the width H1 of the first overlapping region. For example, in Figure 9 the embodiment shown, the second light filtering portion 222 and the data line 13 have no overlap in the positive projection on the second substrate 21. Thus, it is further possible to prevent the second light filtering portion 222 with a higher light transmittance from entering the first light filtering portion 221 with a lower light transmittance, and prevent the second light filtering portion 222 with a higher light transmittance from entering the third light filtering portion 223 with a lower light transmittance, thereby avoiding problems such as lattice points and color mixing. At the same time, by setting the width of the third overlapping region equal to the width of the first overlapping region, the uniformity of the brightness of the transmitted light of the third light filtering portion 223 can also be ensured.

[0091] In some embodiments, as Figure 8 shown, the width H8 of the data line 13 is not less than 0.2 times the minimum width H9 of the color filter portion 220. For example, the width H8 of the data line 13 can be 0.2 times, 0.21 times, 0.22 times, 0.23 times, 0.24 times, 0.25 times, etc. of the minimum width H9 of the color filter portion 220. In the embodiments of the present disclosure, the width H9 of the color filter portion 220 can be the same or different. For example, in Figure 8 the embodiment shown, the widths of the first light filtering portion 221 and the third light filtering portion 223 are the same and different from the width of the second light filtering portion 222. Among them, the width of the second light filtering portion 222 is the smallest. Therefore, in this embodiment, the width of the data line 13 is not less than 0.2 times the width of the second light filtering portion 222.

[0092] For example, in one example, the widths of the color filter portions 220 are all 19 μm, and among them, the width of the data line 13 is 4 μm, which can effectively avoid color mixing between adjacent color filter portions 220.

[0093] In an embodiment of the present disclosure, the first light filtering portion 221 is configured to transmit red light, the second light filtering portion 222 is configured to transmit green light, and the third light filtering portion 223 is configured to transmit blue light.

[0094] In other embodiments, as Figure 10 shown, a display panel provided by the present disclosure includes a color filter substrate 2 and an array substrate 1 which are oppositely arranged. Among them, the array substrate 1 includes a first substrate 11 and a plurality of gate lines 12 and a plurality of data lines 13 disposed on the first substrate 11. The gate lines 12 and the data lines 13 intersect with each other to define a plurality of pixel regions P. The color filter substrate 2 includes a second substrate 21 and a color filter layer 22 on one side of the second substrate 21. The color filter layer 22 includes a plurality of color filtering portions 220. In an embodiment of the present disclosure, the widths H9 of the color filtering portions 220 are the same. The width H8 of the data line 13 is not less than 0.2 times the width H9 of the color filtering portion 220. For example, the width H8 of the data line 13 may be 0.2 times, 0.21 times, 0.22 times, 0.23 times, 0.24 times, 0.25 times, etc. of the width H9 of the color filtering portion 220.

[0095] In an embodiment of the present disclosure, by increasing the width of the data line 13, it can be ensured that the first light filtering portion 221 and the data line 13 have a first overlapping region in the positive projection on the second substrate 21, the second light filtering portion 222 and the data line 13 have a second overlapping region in the positive projection on the second substrate 21, and the third light filtering portion 223 and the data line 13 have a third overlapping region in the positive projection on the second substrate 21. Further, by setting the width H8 of the data line 13 to be not less than 0.2 times the width H9 of the color filtering portion 220, the widths of the first overlapping region, the second overlapping region, and the third overlapping region can be ensured, thereby improving the light shielding effect of the data line 13 and further avoiding the problems of color mixing and grid points.

[0096] Optionally, in an embodiment of the present disclosure, there may be a gap between two adjacent color filtering portions 220. For example, in the embodiment as Figure 10 shown, there is a gap between the adjacent first light filtering portion 221 and the second light filtering portion 222. There may also be a mixed overlap at the splicing position between two adjacent color filtering portions 220. For example, in the embodiment as Figure 10 shown, a part of the adjacent third light filtering portion 223 is on the side of the second light filtering portion 222 away from the second substrate 21 and overlaps with the second light filtering portion 222. Of course, when the process accuracy is high enough, two adjacent color filtering portions 220 can be exactly matched and spliced.

[0097] Optionally, the color filter substrate 2 in the display panel according to the embodiments of the present disclosure further includes a black matrix 23 stacked with the color filter layer 22. The black matrix 23 includes a plurality of first light-shielding bars 231 arranged along the extension direction of the data line 13, and there is a light-transmitting hole between two adjacent first light-shielding bars 231. A plurality of color filter portions 220 in the same row correspond to the same light-transmitting hole.

[0098] In the embodiments of the present disclosure, increasing the width H8 of the data line 13 so that the width H8 of the data line 13 is not less than 0.2 times the width H9 of the color filter portion 220 can effectively avoid color mixing between adjacent color filter portions 220. For example, in one example, the widths of the color filter portions 220 are all 19 μm, and among them, the width of the data line 13 is 4 μm, which can effectively avoid color mixing between adjacent color filter portions 220. When the width of the data line 13 is less than 4 μm, the color mixing problem of adjacent color filter portions 220 will affect the use experience of the display panel.

[0099] In a second aspect, the present disclosure provides a color filter substrate 2. In some embodiments, as Figure 11 shown, the color filter substrate 2 provided by the present disclosure includes: a second substrate 21 and a color filter layer 22 located on one side of the second substrate 21. The color filter layer 22 includes a plurality of color filter portions 220.

[0100] The plurality of color filter portions 220 include a first filter portion 221, a second filter portion 222, and a third filter portion 223; the light transmittance of the first filter portion 221 is less than the light transmittance of the second filter portion 222, and the light transmittance of the first filter portion 221 is greater than the light transmittance of the second filter portion 222.

[0101] The first filter portion 221 includes a first main body portion 2211 and a first extending portion 2212 connected to the first main body portion 2211. The thickness D1 of the first main body portion 2211 is greater than the thickness D2 of the first extending portion 2212, and the thickness D3 of the third filter portion 223 is greater than the thickness D2 of the first extending portion 2212. The first extending portion 2212 is located on the side of the third filter portion 223 away from the second substrate 21.

[0102] The second filter portion 222 includes a second main body portion 2221 and a second extending portion 2222 connected to the second main body portion 2221. The thickness D4 of the second main body portion 2221 is greater than the thickness D5 of the second extending portion 2222. The thickness D3 of the third filter portion 223 is greater than the thickness D5 of the second extending portion 2222. The second extending portion 2222 is located on the side of the third filter portion 223 away from the second substrate 21.

[0103] In the embodiments of the present disclosure, the second protruding portion 2222 is located on the side of the third light filtering portion 223 away from the second substrate 21. The second protruding portion 2222 being located on the side of the third light filtering portion 223 away from the second substrate 21 can avoid color mixing and lattice problems caused by gaps between adjacent color filter portions 220. At the same time, the thickness D1 of the first main body portion 2211 is greater than the thickness D2 of the first protruding portion 2212, the thickness D3 of the third light filtering portion 223 is greater than the thickness D2 of the first protruding portion 2212, the thickness D4 of the second main body portion 2221 is greater than the thickness D5 of the second protruding portion 2222, and the thickness D3 of the third light filtering portion 223 is greater than the thickness D5 of the second protruding portion 2222, which can ensure the light transmission uniformity of the first light filtering portion 221, the second light filtering portion 222, and the third light filtering portion 223.

[0104] In some embodiments, the color film substrate 2 in the embodiments of the present disclosure further includes a black matrix 23 stacked with the color film layer 22. The black matrix 23 includes a plurality of first light shielding strips 231 arranged in the column direction, and there is a light passing hole between two adjacent first light shielding strips 231. The plurality of color filter portions 220 are arranged in multiple rows and multiple columns. The plurality of color filter portions 220 in the same row correspond to the same light passing hole.

[0105] It should be noted that in the embodiments of the present disclosure, the column direction corresponds to the extending direction of the data line 13 in the array substrate 1, and the row direction in which the color filter portions 220 are arranged corresponds to the extending direction of the gate line 12 in the array substrate 1.

[0106] In other embodiments, as Figure 12 shown, the color film substrate 2 provided by the present disclosure includes a second substrate 21, a color film layer 22 and a black matrix 23 that are located on one side of the second substrate 21 and stacked. The color film layer 22 includes a plurality of color filter portions 220; the plurality of color filter portions 220 include a first light filtering portion 221, a second light filtering portion 222, and a third light filtering portion 223. The light transmittance of the first light filtering portion 221 is less than the light transmittance of the second light filtering portion 222, and the light transmittance of the first light filtering portion 221 is greater than the light transmittance of the third light filtering portion 223.

[0107] The black matrix 23 includes a plurality of first light shielding strips arranged along the extending direction of the data line 13 and second light shielding strips connected between two adjacent first light shielding strips, and two adjacent first light shielding strips and two adjacent second light shielding strips define a light passing hole.

[0108] A plurality of color filter units 220 are arranged in multiple rows and columns. Multiple color filter units 220 in the same row form multiple repeating units. Each repeating unit includes a second filter unit 222, a first filter unit 221, and a third filter unit 223 arranged in sequence, and the same repeating unit corresponds to the same light transmission hole. The positive projection of the second light-shielding strip 232 on the second substrate 21 overlaps with the positive projections of two adjacent repeating units on the second substrate 21. Specifically, among two adjacent repeating units, the second filter unit 222 of one repeating unit is adjacent to the third filter unit 223 of the other repeating unit. Therefore, it can also be understood that the positive projection of the second light-shielding strip on the second substrate 21 overlaps with the positive projection of the second filter unit 222 in one repeating unit on the second substrate 21, and overlaps with the positive projection of the third filter unit 223 in the other repeating unit on the second substrate 21. The embodiments of the present disclosure can effectively avoid color mixing and moiré problems between adjacent second filter units 222 and third filter units 223.

[0109] Optionally, in the embodiments of the present disclosure, there may be a gap between two adjacent color filter units 220. For example, in the embodiment as Figure 12 shown, there is a gap between the adjacent third filter unit 223 and the second filter unit 222. Among them, when the process accuracy is high enough, the gap width between the adjacent third filter unit 223 and the second filter unit 222 can be 0, that is, the adjacent third filter unit 223 and the second filter unit 222 can be exactly matched and spliced. There may also be a mixed overlap at the splicing position of two adjacent color filter units 220. For example, in the embodiment as Figure 12 shown, the first protruding portion 2212 of the adjacent first filter unit 221 is on the side of the second filter unit 222 away from the second substrate 21, and the first protruding portion 2212 overlaps with the second filter unit 222.

[0113] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present disclosure. However, the present disclosure is not limited thereto. For those of ordinary skill in the art, various variations and improvements can be made without departing from the spirit and essence of the present disclosure, and these variations and improvements are also regarded as the protection scope of the present disclosure.
