Abstract
We demonstrate new approach of polyimide (Pl)-less polymer stabilized vertical alignment (PS-VA) mode in which binary mixture of single kind of reactive mesogen and LC induces a VA with temperature treatment. The induced VA is fixed at first UV exposure and then a pretilt angle is generated with second UV exposure. The proposed device with two-step UV exposure exhibits excellent electro-optics such as fast response time and enhanced on-state transmittance. This approach fixes a vertical alignment physically unlike chemical bonding in conventional PI-less VA mode, giving rise to high reliability.
