The embodiment of the application provides a photosensitive resin composition for forming a Black Matrix (BM). Specifically, the photosensitive resin composition at least comprises a light-shielding material, a photoinitiator and a polymer; wherein the shading material comprises microcapsules wrapped with metal nano materials. Of course, the photosensitive resin composition may further include other additives, which are not limited herein.
Specifically, the particle size range of the microcapsules is less than 5 microns; when the particle size of the microcapsule is less than 5 microns, the microcapsule is not easy to aggregate due to the accelerated Brownian motion, so that the microcapsule in the application can replace the conventional dispersing agent and plays a role of the dispersing agent. It is understood that the photosensitive resin composition in the embodiment of the present application does not require an additional dispersant.
It is to be understood that the focus of the present application is on the improvement of the light-screening material, and that the photoinitiator and the polymer are not changed, and conventional materials may be used for the photoinitiator and the polymer, which are not specifically described herein.
Specifically, the material of the microcapsule includes an organic polymer, and the microcapsule is composed of an organic polymer film. The material of the microcapsule is not limited and can be adjusted according to the production conditions.
It should be noted that the light-shielding material is a metal nanomaterial that functions to shield light. In one embodiment, the metallic nanomaterial comprises nanocopper; compared with carbon black and copper, the nano copper has excellent light absorption performance and insulating performance, namely, the nano copper has excellent performances such as low reflectivity, high optical density and insulativity, and therefore, a precondition is provided for the subsequent manufacture of the ultrathin antistatic black matrix.
Specifically, the microcapsules release the metal nano-material (such as nano-copper) at a predetermined temperature range. In one embodiment, the predetermined temperature range is greater than 200 ℃ and less than 300 °; in another embodiment, the predetermined temperature range is greater than or equal to 300 ℃. It is understood that the light-shielding material of the present application is resistant to high temperature, i.e., has high stability.
In the embodiment of the present application, the light-shielding material in the photosensitive resin composition is a microcapsule coated with a metal nanomaterial (e.g., nanocopper); on one hand, the microcapsule has small particle size and is not easy to aggregate, and the microcapsule can release metal nano materials (such as nano copper) at ultrahigh temperature, so that the photosensitive resin composition has strong dispersibility and stability, is easy to store and transport, and cannot be deteriorated along with the change of process parameters; on the other hand, the metal nano material (such as nano copper) has excellent performances such as low reflectivity, high optical density and insulativity, and is beneficial to manufacturing an ultrathin anti-static black matrix; therefore, the photosensitive resin composition in the embodiment of the application has wide application prospect.
As shown in fig. 1 and fig. 2, an embodiment of the present application provides a method for manufacturing a black matrix, where the method includes steps S101 to S103.
Step S101: forming a photosensitive resin composition including at least a light-shielding material, a photoinitiator, and a polymer; wherein the shading material comprises microcapsules wrapped with metal nano materials.
Specifically, the photosensitive resin composition in the embodiment of the present application is the photosensitive resin composition in the foregoing embodiment, and specific reference is made to the foregoing embodiment, which is not repeated herein.
Specifically, step S201 includes the following steps:

the light-shielding material is mixed with a photoinitiator and a polymer to form a photosensitive resin composition.
Step S102: a substrate is provided and a photosensitive resin composition is coated on the substrate to form a light-shielding film.
Specifically, a glass substrate is usually used as the substrate, and the photosensitive resin composition produced in step S101 may be applied to the glass substrate by blade coating.
For convenience of explanation, the light-shielding material of the embodiment of the present application is described by taking a microcapsule coated with nano copper as an example; as shown in fig. 2, a photosensitive resin composition is coated on a substrate 1 to form a light-shielding film 2, and each microcapsule 3 in the light-shielding film is coated with nano copper 4.
Since the nano copper 4 has good optical density, compared with black pigment carbon black, if a black matrix with the same optical density is formed, the amount of the photosensitive resin composition in the application is only 40% to 70% of the prior art; therefore, the photosensitive resin composition of the embodiment of the present application can be used to prepare a black matrix, which can save materials and can also prepare a black matrix with higher optical density and low film thickness. It can be understood that the black matrix prepared by the embodiment of the application has good shading performance and small film thickness, and the smoothness of a color film cannot be influenced.
Step S103: the light-shielding film is patterned to form a black matrix.
Specifically, step S103 includes the following steps:
the light-shielding film was subjected to vacuum drying (VCD), prebaking (HP), exposure, development, and baking (Oven) in this order to form a black matrix.
As shown in fig. 2, the black matrix 10 is formed by patterning the light-shielding film 2.
The microcapsules in the embodiment of the present application have good dispersibility and stable performance at high temperature, so the number of the photosensitive resin small black dots in the black matrix formed in the embodiment of the present application is only about 10% of that in the prior art. It can be understood that the light-shielding material in the embodiment of the present application is not prone to the occurrence of the clustering phenomenon.
Specifically, the black matrix prepared in the embodiment of the present application may be applied to a color film of a display panel, and is used for spacing a red color resistor, a green color resistor, and a blue color resistor (certainly not limited to the listed color resistors), so as to play roles in blocking light and improving contrast.
In the embodiment of the present application, the prepared black matrix 10 has a low film thickness, and also has good light-shielding properties, a low reflectance, good antistatic properties, and good stability.
As shown in fig. 3, the embodiment of the present application further provides a display panel 20, where the display panel 20 includes a first substrate 5 and a second substrate 6 that are oppositely disposed; wherein, the first substrate 5 is provided with the black matrix described in the foregoing embodiment; the material of the black matrix includes the photosensitive resin composition in the foregoing embodiments, which is not described herein.
Specifically, the manufacturing method of the black matrix includes the manufacturing method of the black matrix in the foregoing embodiment.
In one embodiment, the display panel 20 further includes a liquid crystal layer 7 between the first substrate 5 and the second substrate 6; the first substrate 5 is a color film substrate, and the second substrate 6 is an array substrate; in another embodiment, the first substrate 5 is an array substrate and the second substrate 6 is a counter substrate. It can be understood that when the first substrate 5 is an array substrate, the display panel is a COA type display panel, that is, a color film is formed on the array substrate.
Of course, in other embodiments, the display panel 20 may also be another type of display panel having a black matrix, and is not limited to the examples listed in this application.
In the embodiment of the present application, the black matrix in the display panel 20 has a low film thickness, and at the same time, has good light shielding performance, a low reflectivity, good antistatic performance, and good stability, which is beneficial to the flatness of the color film.
In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.
The photosensitive resin composition, the method for manufacturing the black matrix, and the display panel provided in the examples of the present application are described in detail above, and the principles and embodiments of the present application are explained herein by applying specific examples, and the description of the examples is only provided to help understanding the technical solutions and the core ideas of the present application; those of ordinary skill in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the spirit and scope of the present disclosure as defined by the appended claims.
