Abstract
A liquid crystal lens and an imaging device including the liquid crystal lens are provided. The liquid crystal lens includes: a first substrate and a second substrate arranged opposite to each other; a liquid crystal layer located between the first substrate and the second substrate; the liquid crystal layer is configured to transmit a first portion of incident light transmitted through the first substrate, and converge the first portion of incident light to a predetermined region of the second substrate; and a light adjustment structure arranged between the first substrate and the second substrate, and configured to enable a second portion of incident light transmitted through the first substrate to be transmitted through the liquid crystal layer and converged to the predetermined region.
