Abstract
A phase shifter, a phase shift degree compensation device, and a phase shift degree compensation method are provided. The phase shifter includes a first substrate and a second substrate that are oppositely arranged, a resonant circuit, a signal line, and a first alignment layer are on a side of the first substrate facing the second substrate, a conductive layer and a second alignment layer are on a side of the second substrate facing the first substrate, a liquid crystal layer is between the first alignment layer and the second alignment layer, and the resonant circuit is configured to detect an actual equivalent dielectric constant of the liquid crystal layer.
