An electron beam addressed crystal light valve (LCLV) produces an AC voltage across a liquid crystal layer from a single polarity electron beam, and exhibits very high resolution. A mirror and a thin layer of partially conductive material are deposited on a support membrane on the electron beam side of the liquid crystal. The partially conductive layer is divided into a series of pixel elements by a conductive matrix which faces the electron beam. Electrons from the beam are absorbed by the partially conductive layer to establish a negative voltage across the liquid crystal, and then flow out to the conductive matrix to produce an AC voltage prior to the next electron beam scan. The conductive matrix is connected in circuit with a transparent electrode which provides a voltage reference on the readout side of the liquid crystal. The elements of the device are designed with electrical parameters that produce a discharge rate from the partially conductive layer fast enough to complete an AC cycle between successive electron beam scans, but slow enough for the liquid crystal to respond and produce an image.
