Microlens Array Based on Electronic Pattering Method using Electrohydrodynamic Instability

Abstract

We fabricated microlens arrays (MLA) using the electrohydrodynamic instability of the optically anisotropic liquid crystal polymer layer. The instability of the liquid crystal polymer layer with the electric filed could make the anisotropic flow on the patterned electrode, as a result, profile of the lens could be made on the transfer substrate. The optical property of the microlens array could be controlled by the surface property of the transfer substrate.
