[Papers] Dielectric Walls with Slits for Pixel Driving and Fabrication of Holographic Liquid Crystal Phase Modulators

Abstract

We found that a dielectric shield wall structure with slits can achieve individual pixel driving with 1-μm-pitch liquid crystal (LC) pixels for electronic holographic displays with wide field of view. The dielectric shield wall structure, which has dielectric walls between pixels, achieves individual pixel driving in 1-μm-pitch pixels. However, for fabrication, the walls need slits to allow the penetration of liquid material such as LCs and solutions containing alignment material. We evaluated this type of structure with simulations based on the elastic continuum theory of LCs, and clarified that the dielectric shield wall structure with slits at the intersections of the walls can achieve individual pixel driving under the condition of strong anchoring on the walls.
