Abstract

고분자 안정화 블루상 액정셀(Polymer-stabilized blue phase liquid crystal cell)은 <TEX>${\mu}s$</TEX> 단위의 응답속도와 광시야각 및 액정의 배향을 위한 문지름 과정이 필요 없는 장점이 있다. 그러나 높은 구동전압과 낮은 kerr 상수값으로 인해 유도되는 복굴절의 값이 낮아 고분자 안정화 블루상 액정셀의 전기광학특성을 저해하는 요인이 되었다. 본 논문에서는 지그재그 형태의 전극 구조를 제안하고 시뮬레이션을 통하여 제안된 전극 구조를 가지는 액정셀의 투과율 손실 없이 구동전압을 25%이상 낮출 수 있음을 확인하였다. The polymer-stabilized blue phase liquid crystal (BPLC) cell has advantages such as sub-millisecond response time, wide viewing angle and no rubbing process for the alignment of liquid crystals. However, high operating voltage and low kerr constant of the polymer-stabilized blue phase liquid crystal deteriorate the electro-optical characteristic of the polymer-stabilized BPLC cell. In this paper, we proposed novel zig-zag electrode in cell layout and confirmed that proposed electrode shape could reduce an over 25 percent of operating voltage for BPLC cell without degradation of tranmittance by using Kerr constant simulation.
