Abstract

본 발명은 산란 모드의 폴리머 분산 액정을 이용한 반사형 액정표시 소자에 관해 기술한다.The present invention describes a reflective liquid crystal display device using a polymer dispersed liquid crystal in scattering mode.

액정 표시 소자는, 폴리머에 액정이 분산되어 있는 산란형광제어층과, 상기 광제어 층의 전후에 액정의 여기를 위한 전극을 구비하며, 광제어층의 전방과 후방에는 입사광의 편광을 제어하는 편광소자와, 입사광을 반사하는 반사막이 각각 마련되다. 상기 반사막과 이에 인접한 투명전극의 사이에는 편광의 위상차를 보상하는 위상차 보상막이 마련된 점에 그 특징이 있다.The liquid crystal display device includes a scattering fluorescence control layer in which liquid crystal is dispersed in a polymer, an electrode for excitation of liquid crystals before and after the light control layer, and polarization for controlling polarization of incident light in front and rear of the light control layer. The element and the reflecting film which reflect incident light are provided, respectively. A feature of the present invention is that a phase difference compensation film is provided between the reflective film and the transparent electrode adjacent thereto to compensate for the phase difference of polarization.

이러한 본 발명은 직시가 불가능한 종래 산과형 액정표시 소자와는 달리 직시가 가능하고, 특히 응답성이 뛰어나므로 그 적용범위가 매우 넓다.The present invention, unlike the obstetrical liquid crystal display device, which is not directly visible, can be viewed directly, and in particular, its application range is very wide because of its excellent responsiveness.
