In an example, a display device is provided, including a dimming structure and a display panel, where the dimming structure is disposed on a light emitting side of the display panel, fig. 1 is a schematic view of the dimming structure in an example, as shown in fig. 1, the dimming structure includes a first substrate 1 'and a second substrate 2' disposed opposite to each other, a plurality of grooves are disposed on a side of the second substrate 2 'facing the first substrate 1', and a receiving cavity is formed between each groove and the first substrate 1', and the receiving cavity is used for receiving a liquid crystal layer 3'. When the refractive index of the liquid crystal layer 3 'is the same as that of the second substrate 2', the dimming structure is equivalent to a parallel flat plate, and incident light is emitted in parallel, so that the display device can realize 2D display; when the refractive index of the liquid crystal layer 3 'is different from that of the second substrate 2', the dimming structure is equivalent to a lens, and the incident light is refracted, so that the display device can realize 3D display.
In the above-described exemplary dimming structure, the sidewall of each groove is in contact with the first substrate 1', the plurality of receiving cavities are not communicated with each other, and the thickness of the liquid crystal layer 3' formed in the receiving cavity by the conventional vacuum crystallization (VIF)/liquid crystal pre-drop (ODF) process is difficult to be maintained uniform.
In view of this, an embodiment of the present invention provides a dimming structure, and fig. 2a and fig. 2b are schematic diagrams of the dimming structure provided in the embodiment of the present invention, where the liquid crystal layer in fig. 2a is omitted in fig. 2b, and the dimming structure includes, in combination with the schematic diagrams shown in fig. 2a and fig. 2 b: a first substrate 1, a second substrate 2 and a liquid crystal layer 3. The second substrate 2 is disposed opposite to the first substrate 1, and a plurality of grooves 4 are disposed on a side of the second substrate 2 facing the first substrate 1. Each groove 4 and the first substrate 1 form a containing cavity 5 therebetween, and at least two adjacent containing cavities 5 are communicated with each other. The liquid crystal layer 3 is located in the accommodation chamber 5, the liquid crystal layer 3 being arranged to switch between a first state and a second state, wherein the refractive index of the liquid crystal layer 3 in the first state is the same as the refractive index of the second substrate 2, and the refractive index of the liquid crystal layer 3 in the second state is different from the refractive index of the second substrate 2.
Specifically, the liquid crystal layer 3 may be switched between the first state and the second state under the driving of the electric field, for example, when the electric field is applied to the liquid crystal layer 3, the long axis direction of the liquid crystal in the liquid crystal layer 3 is parallel to the thickness direction of the liquid crystal layer 3, and the liquid crystal layer 3 at this time is in the first state, and the refractive index thereof is the same as that of the second substrate 2; when no electric field is applied to the liquid crystal layer 3, the long axis direction of the liquid crystal in the liquid crystal layer 3 is perpendicular to the thickness direction of the liquid crystal layer 3, and the liquid crystal layer 3 at this time is in the second state, and its refractive index is different from that of the second substrate 2. When the liquid crystal layer 3 is in the first state, since the refractive index of the liquid crystal layer 3 is the same as that of the second substrate 2, the light incident into the dimming structure is emitted in parallel, so that the dimming structure is equivalent to a parallel plate, and can be used for realizing 2D display; when the liquid crystal layer 3 is in the second state, since the refractive index of the liquid crystal layer 3 is different from the refractive index of the second substrate 2, light incident into the dimming structure is refracted, and thus the dimming structure is equivalent to a lens, and can be used to realize 3D display.
In this embodiment of the present invention, the plurality of grooves 4 may be arranged in an array, and the side walls of the grooves 4 may be provided with openings, or a space is formed between the side walls of the grooves 4 and the first substrate, so that two adjacent accommodating cavities 5 are mutually communicated, which will be described in detail herein.

In this way, the plurality of support portions 6 may space the first substrate 1 from the second substrate 2, and the plurality of support portions 6 may also be spaced apart from each other, so that a space is formed between the groove 4 and the first substrate 1, and thus the liquid crystal in the liquid crystal layer 3 may flow between the adjacent two accommodation cavities 5 through the space.
In another example, the support portions 6 may be provided correspondingly between any adjacent two of the accommodation chambers 5, thereby improving the stability of the support. For example, as shown in fig. 4b, fig. 4b shows four grooves 4 among the plurality of grooves 4 of the dimming structure, the four grooves 4 are arranged in the left-right direction in fig. 4b, each groove 4 forms a receiving cavity 5 with the first substrate 1, and three supporting parts 6 are correspondingly provided between any two receiving cavities 5.
