Four Domain Vertical Aligned Nematic Mode by Rubbing

Abstract

This paper presents a technique for producing a multi-domain VA mode using the conventional rubbing method, which is very simple LC alignment method with low cost. This method is characterized by an aluminum (Al) layer to block rubbing. The Al layer was deposited by low energy thermal evaporation that does not damage the polyimide surface. A simulation and simple experiments were performed to examine the possibility of a multi-domain VA mode using the conventional rubbing method. The proposed multi-domain VA mode will show a rapid response speed and high transmittance due to the lack of disclination formation in a LC cell, compared to the conventional VA modes.
