Abstract

전방 편광판 (1)과 후방 편광판(8)을 갖는 액정셀로 구성되어 서로 다른 색상을 발생시키기 위한 액정표시장치(100)에 있어서, 상기 후방 극성(8)은 광학적으로 투과성이고, 반사성 및/또는 굴절성이다. 후방 편광판(8)이 투과성이거나 혹은 굴절성인 경우에 광대역을 갖는 광전원(9)이 영상의 질을 높이기 위해 제공된다. 셀감속체에서 변화를 야기시키는 전계의 작용에 의해 액정표시장치에 있어서 다양한 색상이 발생되어진다. 제1실시예에 있어, 감속층은 다른 색상을 발생시키기 위한 전방편광판(1)과 액정셀의 다른 요소 사이에 설치되어진다.
