Abstract

The liquid crystal(LC) display is the most promising technology of the flat panel displays covering all applications from small mobile to large television applications. To understand the operating principles and improve the performances of the various LC displays, one should grasp the anisotropic nature of the LC and the propagation of light in the anisotropic media. Basic formulas governing the distribution of the LC molecules, directly related to the electro-optic effects of the LC devices, are described in view of the macroscopic interaction. Based on the matrix representation, the polarization analysis for the LC devices is also presented.

액정 디스플레이는 소형에서 대형까지 모두 이용 가능한 가장 확실한 평판 디스플레이 구현 기술로 각광받고 있다. 액정 디스플레이의 동작 원리뿐 만 아니라 성능 개선을 위해, 액정의 비등방성 및 비등방 매질에서 빛의 전파에 대한 이해가 필요하다. 액정 소자의 광학 특성에 영향을 주는 액정의 공간 분포에 관여하는 에너지를 통해 액정 디스플레이의 동작원리를 이해하고, 비등방 매질에서 빛의 편광 해석 방법을 통해 액정 디스플레이의 광학특성에 대해 기술한다.
