1. A display device, comprising:
a display module and a function module;
the display module comprises a first substrate, a plurality of light emitting units, a third substrate and an array substrate;
the plurality of light emitting units are located on a surface of the third substrate,
the array substrate is located on another surface of the third substrate away from the light emitting units;
the first substrate is located on a surface of the array substrate away from the third substrate;
the plurality of light emitting units are located on a side of the first substrate, a light emitting direction of the light emitting units are oriented towards the first substrate;
the function module is located on a surface of the first substrate away from the light emitting units;
a surface of the function module close to the first substrate is in direct contact with the surface of the first substrate away from the light emitting units, the function module is configured for spinning light of the light emitting units so that the light is concentrated towards a visible area, which changes a size of an original visible area of the display module, wherein the original visible area is greater than the visible area;
wherein
the function module comprises a first electrode layer, a functional liquid crystal layer, a second electrode layer and a second substrate;
the first electrode layer is located on a surface of the first substrate away from the light emitting units;
a surface of the first electrode layer close to the first substrate is in direct contact with the surface of the first substrate away from the light emitting module;
the functional liquid crystal layer is located on a surface of the first electrode layer away from the first substrate;
the second electrode layer is located on a surface of the functional liquid crystal layer away from the first electrode layer;
the second substrate is located on a surface of the second electrode layer away from the functional liquid crystal layer;
a surface of the first electrode layer adjacent to the functional liquid crystal layer and a surface of the second electrode layer adjacent to the functional liquid crystal layer are coated with alignment materials, respectively;
the display module further comprises a driving circuit, wherein
the driving circuit is formed in the first electrode layer or the second electrode layer,
the driving circuit is connected to the first electrode layer or the second electrode layer, and connected to the plurality of light emitting units, and
the driving circuit is configured to drive the plurality of light emitting units to light and provide a driving signal to the first electrode layer or the second electrode layer.
