A light amplification device displaying particular utility in the display of micro intelligence. In a known light amplifier construction employing transparent sheets between which an electric field is impressed, and which employs a photoconductive sheet and an electrically optically active sheet such as a liquid crystal sheet, a novel lattice member is inserted between the photoconductive sheet and the liquid crystal sheet. In one embodiment, the lattice is defined by a plurality of metallic studs mounted in a dielectric sheet. The studs localize the electric field impressed upon the liquid crystal sheet. The resultant display is a gravure display, the studs defining the gravure points. In several embodiments, the location and form of the gravure points are varied. Color displays are also made. The introduction of the lattice lowers the power requirements of the light amplifier.
