Electrical-control liquid crystal plane diffractive micromirror and manufacturing method thereof

The invention discloses an electrical-control liquid crystal plane diffractive micromirror, comprising a first substrate, a first pattern electrode conductor layer, a first insulating layer, a first pattern electrode, a first liquid crystal alignment layer, a liquid crystal layer, a second liquid crystal alignment layer, a second pattern electrode, a second insulating layer, a second pattern electrode conductor layer and a second substrate; each of the first pattern electrode and the second pattern electrode comprises multiple electric-driven loop electrodes which are of the same shape and areunclosed rings; the first pattern electrode conductor layer is provided with a plurality of through holes, and the number of the though holes is the same with that of total terminals of the electric-driven loop electrodes. The electrical-control liquid crystal plane diffractive micromirror solves the technical problem of loss of incident light of the existing diffractive micromirror, and also solves the technical problem
