Abstract

종래의 타블렛일체형 액정표시장치는 STN형 액정표시셀을 통과하는 광의 복굴절에 기인하는 착색현상이 고온환경하 (예를 들어 40℃이상)에서 회피할 수 없어 차량탑재용 제품 등에 적용하였을 때 표시품위의 저하를 일으키기 쉽다.
한쌍의 편광판(1,5)사이에 STN형의 액정표시셀(2)과 타블렛(4)을 배치하고, 이 타블렛(4)의 서로 대향하는 좌표검출용 전극 (15,16)간에 액정표시셀(2)을 통과하는 광의 복굴절에 의한 파장분산을 캔슬하기 위한 보상용 액정층(21)을 개재시킴과 동시에 이 보상용 액정층(21)속에 비도전성 스페이서입자(23)와 도전성입자(24)를 혼입시키는 구성으로 하였다.
