1. A liquid crystal display device, comprising:
a liquid crystal display panel comprising a light transmissive region and a display region;
a backlight plate corresponding to a position of the display region, wherein a via hole is defined on the backlight plate, and a position of the via hole corresponds to a position of the light transmissive region;
an adjustable diffusion sheet configured to improve a light transmissive rate of the light transmissive region, wherein the adjustable diffusion sheet includes a first sub-section, and the first sub-section comprises:
a first substrate comprising a first electrode, wherein the first electrode is disposed on a first side of the first substrate;
a second substrate disposed opposite to the first substrate, wherein the second substrate comprises a second electrode, and the second electrode is disposed on a first side of the second substrate; and
a first adjustable transparency material disposed between the first electrode and the second electrode,
wherein when the light transmissive region is in a transparent state, the first sub-section is in the transparent state, and when the light transmissive region is in a display state, the first sub-section is in a fog state; and
a first light source configured to provide a light source to the light transmissive region when the light transmissive region is in the display state;
wherein the adjustable diffusion sheet comprises a second sub-section, the second sub-section corresponds to the position of the display region, and the second sub-section comprises:
a third substrate;
a fourth substrate disposed opposite to the third substrate; and
a second adjustable transparency material disposed between the third substrate and the fourth substrate, wherein a thickness of the second adjustable transparency material is greater than a thickness of the first adjustable transparency material.
