A color-changing light-adjusting liquid crystal device and a light-adjusting method may include a main liquid crystal and a dichroic dye, which may be filled between substrates disposed oppositely, in a non-powered state. The main liquid crystal may be subjected to a specific arrangement orientation under an induction of an alignment layer, in a powered state, and the main liquid crystal may be subjected to a reorientation. Dichroic dye molecules may be rotated along with the reorientation of the main liquid crystal so as to scatter incident light in a visible spectrum, convert a light-transmitting state into a light-scattering state at a macro level, and display a color of the dichroic dye in the main liquid crystal, thus implementing light adjustment. The color-changing light-adjusting liquid crystal device does not contain a polymer network, so that a polymerization process is not needed and a polymer aging is avoided.
