Description

Technical Field

[0002] In recent years, people have mainly focused on display devices such as mobile phones, tablets, and automotive displays. The demand for display devices has been increasing year by year. However, in bright environments, these display devices often suffer from poor display quality due to their high reflectivity, making it difficult to meet people's needs. Therefore, reducing the reflectivity of display devices is particularly important for improving their display performance.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0012] In some embodiments, the thickness of the third light-shielding layer is 50 nm to 2000 nm along a direction perpendicular to the second substrate.

[0013] In some embodiments, the liquid crystal display panel further includes a high-resistivity film disposed on the side of the second light-shielding layer opposite to the first substrate.

Detailed Implementation

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0023] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this disclosure. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this disclosure provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0024] This disclosure is described below with reference to the accompanying drawings and specific embodiments: This disclosure provides an embodiment of a color filter substrate 100, such as... Figures 1 to 17 As shown, the color filter substrate 100 includes a first substrate 110, a first light-shielding layer 130, a color filter layer 120, and a second light-shielding layer 400. The first light-shielding layer 130 is disposed on a first side of the first substrate 110 and has a plurality of spaced-apart first light-transmitting openings. The color filter layer 120 (CF) is disposed on the first side of the first substrate 110 and includes a plurality of color filter portions disposed at the first light-transmitting openings. The orthographic projection of the color filter portions on the first substrate 110 at least partially overlaps with the orthographic projection of the first light-transmitting openings on the first substrate 110. The second light-shielding layer 400 is disposed on a second side of the first substrate 110, opposite to the first side. The second light-shielding layer 400 has a plurality of spaced-apart second light-transmitting openings, and the orthographic projections of the second light-transmitting openings on the first substrate 110 at least partially overlap with the orthographic projections of the first light-transmitting openings on the first substrate 110.

[0025] The color filter substrate 100 proposed in the embodiments of this disclosure, such as Figures 1 to 17 As shown, a first light-shielding layer 130 is provided on the first side of the first substrate 110, and a second light-shielding layer 400 is provided on the second side of the first substrate 110. The orthographic projection of the second light-transmitting opening on the first substrate 110 and the orthographic projection of the first light-transmitting opening on the first substrate 110 at least partially overlap, so that the second light-shielding matrix formed by the second light-shielding layer 400 can form a first light-shielding matrix with the first light-shielding layer 130 at least partially overlap. In this way, the second light-shielding matrix can absorb the light incident on the color filter substrate 100, thereby reducing the reflectivity of the color filter substrate 100, thereby reducing the reflectivity of the liquid crystal display panel having the color filter substrate 100 and improving the display effect of the liquid crystal display panel.

[0026] In some embodiments of this disclosure, such as Figure 17As shown, optionally, the orthographic projection of the color filter on the first substrate 110 coincides with the orthographic projection of the first light-transmitting opening on the first substrate 110; the orthographic projection of the second light-transmitting opening on the first substrate 110 coincides with the orthographic projection of the first light-transmitting opening on the first substrate 110. It should be noted that, in this disclosure, the "coincidence" between the orthographic projections of the second light-transmitting opening and the first light-transmitting opening on the first substrate 110 is allowed to have a certain degree of error. In the following text of this disclosure, the "coincidence" between other structures is also allowed to have a certain degree of error, which will not be elaborated further.

[0027] In some embodiments of this disclosure, such as Figure 17 As shown, the first light-shielding layer 130 is disposed on the first side of the first substrate 110. The first light-shielding layer 130 has a plurality of first light-transmitting openings spaced apart, thereby forming a first light-shielding matrix on the first side of the first substrate 110. The first light-shielding matrix can reduce the reflectivity of ambient light to a certain extent, thereby reducing the reflectivity of the liquid crystal display device having the color filter substrate 100.

[0028] In some embodiments of this disclosure, such as Figures 1 to 17 As shown, the second light-shielding layer 400 is disposed on the second side of the first substrate 110, opposite to the first side. The second light-shielding layer 400 has a plurality of second light-transmitting openings spaced apart, thereby forming a second light-shielding matrix on the second side of the first substrate 110. The second light-shielding matrix can further reduce the emissivity to ambient light, and further reduce the reflectivity of the liquid crystal display device having the color filter substrate 100. At the same time, since the second light-shielding layer 400 is located on the side of the first substrate 110 away from the first light-shielding layer 130 and the color filter layer 120, compared with the conventional color filter substrate 100, the color filter substrate 100 of this disclosure has no impact on the functional layer structure of the color filter substrate 100, so that the color filter substrate 100 can use the conventional color filter substrate 100 manufacturing process, which is beneficial to reducing the manufacturing cost of the color filter substrate 100.

[0029] In some embodiments of this disclosure, the material of the first light-shielding layer 130 may include a black light-absorbing material, and the first light-shielding matrix may also be referred to as a black matrix (BM), thereby giving the first light-shielding matrix formed by the first light-shielding layer 130 good light absorption characteristics.

[0030] In some embodiments of this disclosure, the material of the second light-shielding layer 400 may include a black light-absorbing material, and the second light-shielding matrix may also be called a black matrix (BM), thereby giving the second light-shielding matrix formed by the second light-shielding layer 400 better light absorption characteristics.

[0031] In some embodiments of this disclosure, optionally, the black light-absorbing material used in the second light-shielding layer 400 may be the same as the black light-absorbing material used in the first light-shielding layer 130. Alternatively, the black light-absorbing material used in the second light-shielding layer 400 may be different from the black light-absorbing material used in the first light-shielding layer 130, thereby giving the second light-shielding layer 400 and the first light-shielding layer 130 different reflectivities. For example, the reflectivity of the second light-shielding layer 400 may be less than that of the first light-shielding layer 130.

[0032] In some embodiments of this disclosure, such as Figure 17 As shown, the color filter section may include a red filter section 121, a green filter section 122, and a blue filter section 123.

[0033] In some embodiments of this disclosure, the first substrate 110 may be a glass substrate.

[0034] As an alternative implementation method, such as Figure 17 As shown, the orthographic projection of the first light-transmitting opening on the first substrate 110 is located within the orthographic projection range of the color filter on the first substrate 110, and the orthographic projection of the first light-transmitting opening on the first substrate 110 is located within the orthographic projection range of the second light-transmitting opening on the first substrate 110.

[0035] In some embodiments of this disclosure, such as Figure 17 As shown, by placing the orthographic projection of the first light-transmitting opening on the first substrate 110 within the orthographic projection range of the color filter on the first substrate 110, the first light-transmitting opening can avoid the color filter, allowing the color filter to emit light through the first light-transmitting opening. Simultaneously, by placing the orthographic projection of the first light-transmitting opening on the first substrate 110 within the orthographic projection range of the second light-transmitting opening on the first substrate 110, the second light-transmitting opening can avoid both the first light-transmitting opening and the color filter, thereby allowing the color filter to emit light through the second light-transmitting opening.

[0036] In some embodiments of this disclosure, optionally, the orthographic projection of the first light-transmitting opening on the first substrate 110 coincides with the orthographic projection of the second light-transmitting opening on the first substrate 110.

[0037] As an alternative implementation method, such as Figures 1 to 17 As shown, a first groove is provided on the second side surface of the first substrate 110. The depth of the first groove is less than the thickness of the first substrate 110 in a direction perpendicular to the first substrate 110. A second light-shielding layer 400 is disposed in the first groove; or, the second light-shielding layer 400 is stacked on the second side surface of the first substrate 110.

[0038] In some embodiments of this disclosure, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 11 , Figure 13 , Figure 15 as well as Figure 17 As shown, a first groove can be formed on the second side surface of the first substrate 110 by a deep etching process. The depth of the first groove is less than the thickness of the first substrate 110 in a direction perpendicular to the first substrate 110, thereby ensuring the integrity of the first substrate 110. At the same time, a second light-shielding layer 400 is disposed in the first groove. After the second light-shielding layer 400 is provided on the second side of the first substrate 110, the second side surface of the first substrate 110 can be kept flat, which facilitates the subsequent deposition of other functional film layers on the second side of the first substrate 110.

[0039] In some embodiments of this disclosure, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figure 14 as well as Figure 16 As shown, the second light-shielding layer 400 can also be directly stacked on the second side surface of the first substrate 110.

[0040] In some embodiments of this disclosure, a first light-shielding layer 130 may be coated on a prepared first substrate 110, and then an exposure and development process may be used to form a first light-transmitting opening on the first light-shielding layer 130.

[0041] As an alternative implementation method, such as Figure 17 As shown, the color filter substrate 100 also includes a planarization layer 900, which covers the side of the first light-shielding layer 130 and the color filter layer 120 away from the first substrate 110. The planarization layer 900 can be used to protect the first light-shielding layer 130 and the color filter layer 120 and make the side of the first light-shielding layer 130 and the color filter layer 120 away from the substrate flat.

[0042] As an alternative implementation method, such as Figure 17 As shown, the color filter substrate 100 also includes a spacer 910, which is disposed on the side of the planarization layer 900 away from the first substrate 110. The spacer 910 is used to support the color filter substrate 100 and the array substrate 200 to ensure that the spacing between the color filter substrate 100 and the array substrate 200 is stable.

[0043] Based on the same inventive concept, this disclosure also proposes a liquid crystal display panel, such as... Figures 1 to 17 As shown, the liquid crystal display panel includes the aforementioned color filter substrate 100, an array substrate 200 spaced apart from the color filter substrate 100, and a liquid crystal molecule 310 layer located between the color filter substrate 100 and the array substrate 200. The first light-shielding layer 130 and the color filter layer 120 in the color filter substrate 100 are located on the side closer to the array substrate 200.

[0044] Since the liquid crystal display panel provided in this disclosure includes the color filter substrate 100 of the above-mentioned technical solution, the liquid crystal display panel provided in this disclosure has all the beneficial effects of the color filter substrate 100, which will not be elaborated here.

[0045] In some embodiments of this disclosure, the color filter substrate 100 and the array substrate 200 can be aligned using a frame adhesive 800 to encapsulate a liquid crystal molecule 310 layer between the color filter substrate 100 and the array substrate 200. The liquid crystal molecule 310 layer includes a plurality of liquid crystal molecules 310, which rotate within the liquid crystal molecule 310 layer.

[0046] As an optional implementation, the array substrate 200 includes a second substrate 210 and a thin-film transistor (TFT), wherein the second substrate 210 includes a plurality of pixel regions; the thin-film transistor is disposed on the side of the second substrate 210 facing the color filter substrate 100, and the thin-film transistor is located outside the pixel regions.

[0047] In some embodiments of this disclosure, the pixel areas on the second substrate 210 are through which light emitted from the backlight source passes. Thin-film transistors are used to control the rotation direction of the liquid crystal molecules 310 corresponding to each pixel area in the liquid crystal molecule 310 layer by changing their voltage, thereby controlling whether polarized light is emitted from each pixel area to achieve the purpose of displaying each pixel area.

[0048] It should be noted that the first light-transmitting opening of the first light-shielding layer 130 has its orthographic projection on the second substrate 210 at least partially overlaps with the pixel area, so that the light emitted from each pixel area can be emitted through the first light-transmitting opening.

[0049] In some embodiments of this disclosure, the first substrate 110 may be a glass substrate.

[0050] In some embodiments of this disclosure, optionally, the first light-transmitting opening of the first light-shielding layer 130 is projected onto the second substrate 210 and coincides with the pixel area.

[0051] As an alternative implementation method, such as Figures 9 to 16As shown, the liquid crystal display panel also includes a third light-shielding layer 700. The third light-shielding layer 700 is disposed on the side of the second substrate 210 away from the color filter substrate 100. The third light-shielding layer 700 has a plurality of third light-transmitting openings spaced apart. The orthographic projection of the third light-transmitting opening on the second substrate 210 at least partially overlaps with the pixel area. The orthographic projection of the third light-transmitting opening on the second substrate 210 at least partially overlaps with the orthographic projection of the first light-transmitting opening on the second substrate 210.

[0052] In some embodiments of this disclosure, such as Figures 9 to 16 As shown, by providing a third light-shielding layer 700 on the side of the second substrate 210 opposite to the color filter substrate 100, the third light-shielding layer 700 has a plurality of third light-transmitting openings spaced apart, thereby forming a third light-shielding matrix. By making the orthographic projection of the third light-transmitting opening on the second substrate 210 at least partially overlap with the pixel area, and the orthographic projection of the third light-transmitting opening on the second substrate 210 at least partially overlap with the orthographic projection of the first light-transmitting opening on the second substrate 210, the light emitted by the backlight source can pass through the third light-transmitting opening and the pixel area sequentially into the liquid crystal molecule 310 layer, and the light emitted by each pixel area can be emitted through the first light-transmitting opening.

[0053] In some embodiments of this disclosure, optionally, the orthogonal projection of the third light-transmitting opening onto the second substrate 210 coincides with the pixel area.

[0054] In some embodiments of this disclosure, optionally, the orthographic projection of the third light-transmitting opening on the second substrate 210 coincides with the orthographic projection of the first light-transmitting opening on the second substrate 210.

[0055] As an alternative implementation method, such as Figure 9 , Figure 11 ,like Figure 13 as well as Figure 15 As shown, the second substrate 210 has a second groove on the side away from the color filter substrate 100. The depth of the second groove is less than the thickness of the second substrate 210 in a direction perpendicular to the second substrate 210. The third light-shielding layer 700 is disposed in the second groove; or, the third light-shielding layer 700 is stacked on the surface of the second substrate 210 on the side away from the color filter substrate 100.

[0056] In some embodiments of this disclosure, such as Figure 9 , Figure 11 ,like Figure 13 as well as Figure 15A second groove can be formed on the side of the second substrate 210 away from the color filter substrate 100 by a deep etching process. The depth of the second groove is less than the thickness of the second substrate 210 in a direction perpendicular to the second substrate 210, thereby ensuring the integrity of the second substrate 210. At the same time, a third light-shielding layer 700 is disposed in the second groove. After the third light-shielding layer 700 is provided on the side of the second substrate 210 away from the color filter substrate 100, the surface of the side of the second substrate 210 away from the color filter substrate 100 can be kept flat, which facilitates the subsequent formation of other functional film layers on the second side of the second substrate 210.

[0057] In some embodiments of this disclosure, such as Figure 10 , Figure 12 , Figure 14 as well as Figure 16 As shown, the third light-shielding layer 700 can also be directly stacked on the side of the second substrate 210 away from the color filter substrate 100.

[0058] In some embodiments of this disclosure, a third light-shielding layer 700 may be coated on a prepared second substrate 210, and then a first light-transmitting opening may be formed on the third light-shielding layer 700 by an exposure and development process.

[0059] As an alternative implementation, the thickness of the third light-shielding layer 700 is 50nm to 2000nm along the direction perpendicular to the second substrate 210.

[0060] In some embodiments of this disclosure, the thickness of the third light-shielding layer 700 along the direction perpendicular to the second substrate 210 is 50nm to 2000nm, and the specific thickness of the third light-shielding layer 700 can be adjusted according to design requirements. For example, the thickness of the third light-shielding layer 700 can be 50nm, 100nm, 200nm, 300nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900nm, 1000nm, 1100nm, 1200nm, 1300nm, 1400nm, 1500nm, 1600nm, 1700nm, 1800nm, 1900nm, 2000nm, or any other value within the range of 50nm to 2000nm.

[0061] As an alternative implementation method, such as Figures 1 to 17 As shown, the liquid crystal display panel also includes a high-resistivity film 600, which is disposed on the side of the second light-shielding layer 400 away from the first substrate 110.

[0062] In some implementations of this disclosure, such as Figures 1 to 17As shown, a high-resistivity film 600 is provided on the side of the second light-shielding layer 400 away from the first substrate 110. The high-resistivity film 600 is a film material with a high resistance value, so that the high-resistivity film 600 can play the role of current isolation and voltage control, thereby improving the display accuracy of the liquid crystal display panel and reducing interference between pixel areas.

[0063] As an alternative implementation method, such as Figures 3 to 4 , Figures 7 to 8 , Figures 11 to 12 , Figures 15 to 16 As shown, the high-resistivity film 600 covers the second light-shielding layer 400, and the high-resistivity film 600 has a plurality of fourth light-transmitting openings spaced apart. The fourth light-transmitting openings on the first substrate 110 and the second light-transmitting openings on the first substrate 110 at least partially overlap in orthographic projection.

[0064] In some embodiments of this disclosure, such as Figures 3 to 4 , Figures 7 to 8 , Figures 11 to 12 , Figures 15 to 16 As shown, the high-resistivity film 600 has a plurality of fourth light-transmitting openings spaced apart, which allows the high-resistivity film 600 to completely cover the second light-shielding layer 400, or to cover a portion of the second light-shielding layer 400. Simultaneously, the fourth light-transmitting openings on the first substrate 110 at least partially overlap with the second light-transmitting openings projected onto the first substrate 110, thereby allowing the fourth light-transmitting openings to avoid the second light-transmitting openings (pixel areas). This prevents light emanating from the second light-transmitting openings (pixel areas) from passing through the high-resistivity film 600, thereby increasing the transmittance of light emanating from the second light-transmitting openings (pixel areas), and thus improving the transmittance and luminous efficiency of the liquid crystal display panel. Furthermore, since the high-resistivity film 600 can avoid the second light-transmitting openings (pixel areas) through the fourth light-transmitting openings, it can prevent external light from being reflected off the high-resistivity film 600 at the second light-transmitting openings (pixel areas), thereby reducing the reflectivity of the liquid crystal display panel in the pixel areas.
