We propose a method for the multi domain alignment of liquid crystals (LCs) through ion beam exposure. We have demonstrated the multi domain ion-beam vertical alignment (IVA) of LC on SiOx film surfaces using a stainless steel mask. We found that IVA cells require a polar anchoring energy higher than $2\times 10^{-4}$ J/m2. The disclination linewidth of an IVA cell decreased from 45 to 13 μm with an increase in polar anchoring energy from 2 to $5.8\times 10^{-4}$ J/m2. The turn-on time of an IVA cell was 35% faster than that of a patterned vertical alignment cell.
