The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The drawings are for illustrative purposes only and are merely schematic representations, not intended to limit the present patent.
Referring to fig. 1, the present invention provides an array substrate 100, wherein the array substrate 100 includes a substrate 10, a reflective layer 20 and an alignment layer 30 sequentially stacked on the substrate 10. One surface of the alignment layer 30 is attached to one surface of the reflective layer 20. The alignment layer 30 includes a polymer, the polymer forms an uneven layer structure 33 in the alignment layer, and the layer structure 33 is located on the surface of the alignment layer 30, which is attached to the reflective layer 20.
The reflective layer 20 is stacked on the base substrate 10, and reflects light irradiated onto the reflective layer 20. In the present invention, the reflective layer 20 is a metal thin film layer formed by vapor deposition or magnetron sputtering, and the metal thin film layer has a good reflection effect on light, so as to reflect light irradiated onto the reflective layer 20. In this embodiment, the reflective layer 20 is an aluminum metal thin film layer. Further, the substrate base plate 10 is further provided with thin film transistors and wirings arranged in an array manner, and pixel electrodes stacked on the thin film transistors and electrically connected with the thin film transistors through via holes. The reflective layer 20 is stacked on the pixel electrode layer. In this embodiment, the pixel electrode is formed of the same material as the reflective layer 20, so that the kind of material used can be reduced, thereby reducing the manufacturing cost.
The alignment layer 30 serves to align liquid crystals. In the present invention, the alignment layer 30 includes a polymer, and the polymer is dispersedly formed in the alignment layer 30. And, the polymer positioned on the surface where the alignment layer 30 is attached to the reflective layer 20 forms an uneven layer structure 33. Specifically, the layer structure 33 includes a plurality of spaced apart polymer clusters 31 formed by agglomeration of the polymer. And, since the polymer masses 31 are arranged at intervals, the layer structure 33 is an uneven structure. And the layer structure 33 formed by the polymer group 31 is located on the surface where the alignment layer 30 and the reflection layer 20 are attached, so that when external light irradiates the reflection layer 20, the layer structure 33 with unevenness formed by the polymer can make the light generate diffuse reflection, thereby realizing a good diffuse reflection effect of the array substrate on the external light. In other words, the rugged layer structure 33 is disposed on the surface of the alignment layer 30 attached to the reflective layer 20, and when light is irradiated into the array substrate 100, the surfaces of the reflective layer 20 and the layer structure 33 are used as reflective surfaces, so that the light incident into the array substrate 100 is diffusely reflected due to the rugged structure. Further, in order to enhance the diffuse reflection effect of the array substrate 100 on the external light, the formed polymer has a good light reflection effect, so that the surface of the layer structure 33 has a good light reflection effect. In other words, the reflective surface of the layer structure 33 facing away from the reflective layer 20 has a good light-reflecting effect. In addition, compared with the prior art, the manufacturing process of the array substrate does not need to be increased, and the manufacturing cost and the manufacturing time are reduced. Compared with the prior art, the array substrate 100 of the invention does not need to process the reflective layer 20 again, and does not need to reserve the processing thickness of the reflective layer, so that the thickness of the reflective layer 20 can be reduced. In this embodiment, the polymer is formed by polymerizing a graft monomer. Specifically, the graft monomer is mixed in the alignment material forming the alignment layer 30. The grafting monomer is an ultraviolet light sensitive material, and the grafting monomer is polymerized under the irradiation of ultraviolet light for curing the alignment layer 30 to form the polymer. The polymer is dispersed in the alignment layer 30, but due to the thin thickness (about 100 μm) of the alignment layer 30, the polymer is located approximately on the surface where the alignment layer 30 and the reflective layer 20 are attached, so that the surface where the reflective layer 20 and the alignment layer 30 are attached has an uneven structure. It is understood that the grafting monomer may also be a heat-sensitive material according to the kind of the grafting monomer, and the grafting monomer may be polymerized under the heat baking for fixing the alignment layer 30, thereby forming the polymer.

Specifically, the alignment material and the grafting monomer are mixed, in the mixing process, the grafting monomer is grafted on the main chain of the alignment material of the alignment layer 30 to form the modified alignment material, and the modified alignment material is subjected to a polymerization reaction under the irradiation of ultraviolet light for curing the alignment layer 30 or under the action of thermal baking, so as to form the polymer.

Accordingly, the effect of the diffuse reflection of the reflective layer 20 can be achieved without re-processing the reflective surface of the reflective layer 20, and thus, the manufacturing process of the array substrate 100 does not need to be increased, and the manufacturing cost and time are reduced.
Further, referring to fig. 2, the present invention further provides a reflective liquid crystal display panel 200, which utilizes ambient light to realize image display of the reflective liquid crystal display panel 200 by reflecting the ambient light, does not need a backlight source with high energy consumption, and can be better applied to various displays, especially mobile devices and wearable display devices.

The alignment layer 111 on the color filter substrate 110 is the same as the alignment layer 30 in the prior art, and does not include the polymer, which is not described herein again. Since the array substrate 100 can realize the effect of diffuse reflection of the reflective layer 20 without reprocessing the reflective surface of the reflective layer 20, the manufacturing cost and time can be reduced, so that the reflective liquid crystal display panel 200 including the array substrate 100 can also reduce the manufacturing cost and time.

I.e. the grafting monomer is
According to different types of the grafting monomers, the grafting monomers can be ultraviolet light sensitive type or heat sensitive type. The ultraviolet-sensitive grafting monomer is easy to generate a polymerization reaction under the irradiation of ultraviolet light, and the heat-sensitive grafting monomer is easy to generate a polymerization reaction under the heat baking. The alignment material can be polyimide, polyamide acid or polyamide acid ester material.
In step 130, please refer to fig. 5, the alignment agent is deposited on a surface of the reflective layer 20 opposite to the substrate 10 to form an alignment agent layer 32.
The alignment agent layer 32 is formed on the side of the reflective layer 20 opposite to the base substrate 10 by any one of inkjet printing, spray coating, blade coating, or dip coating.
The alignment agent layer 32 is selectively treated by ultraviolet irradiation or thermal baking according to the selected type of the grafting monomer. The alignment material in the alignment agent layer 32 is cured by ultraviolet irradiation or thermal baking of the alignment agent layer 32, so that the alignment layer 30 is formed to have an alignment effect. And, by the action of ultraviolet irradiation or thermal baking, the alignment agent reacts to generate a polymer, i.e. the alignment layer 30 includes a polymer, and the polymer is dispersed and formed in the alignment layer 30. And, the polymer positioned on the surface where the alignment layer 30 is attached to the reflective layer 20 forms an uneven layer structure 33. Specifically, the polymer generated by the reaction in the alignment agent is agglomerated to form a polymer cluster 31, and the polymer cluster 31 located on the surface where the alignment layer 30 and the reflective layer 20 are attached forms the layer structure 33, that is, the layer structure 33 is located on the surface where the alignment layer 30 and the reflective layer 20 are attached. Further, by controlling the amount of the graft monomer added to the alignment agent, the formation density of the polymer clusters 31 can be controlled. In this embodiment, the formation density of the polymer clusters 31 is controlled, so that the polymer clusters 31 in the layer structure 33 are spaced, and the layer structure 33 is an uneven structure, so that when external light irradiates the reflective layer 20, the uneven layer structure 33 formed by the polymer makes the light diffuse, thereby achieving a good diffuse reflection effect of the array substrate on the external light. Further, since the reaction environments of the respective positions in the alignment agent are the same, the structures of the polymer clusters 31 in the alignment layer 30 are the same, so that the structures of the polymer patterns 31 in the layer structure 33 are substantially the same, and further, the diffuse reflection of the respective positions of the array substrate to the external light is more uniform, thereby further increasing the diffuse reflection effect of the array substrate.
Further, the polymer formed is different according to the different alignment agents. In this embodiment, the alignment agent is a mixture of the alignment material and a grafted monomer material, and the polymer is formed by polymerization reaction of the grafted monomer. In other embodiments of the present invention, the alignment agent is the modified alignment material formed by grafting the grafting monomer onto the main chain of the alignment material, and the polymer is formed by polymerizing the modified alignment material.

That is, the uneven layer structure is formed while the alignment layer for alignment is formed, so that a good diffuse reflection effect on external light can be achieved, and compared with the prior art, the manufacturing process of the array substrate does not need to be increased, and the manufacturing cost and time are reduced.
