Abstract

본 발명은 서브백라이트를 구비한 디스플레이장치에 관한 것으로서, 서브백라이트의 광원이 직접 메인디스플레이화면의 릴 또는 물체에 도달하여 전방으로 반사됨으로 인해 발생되는 불명료한 시야를 방지할 수 있는 디스플레이장치이다. 본 발명의 서브백라이트유닛(40)은 투시창(16)에 대응하도록 개구부(42)가 형성된 제2도광판(41)과, 상기 도광판(41)의 둘레부에 배치되는 제2광원(43)과, 상기 제2도광판(41)의 개구부(42)의 전방에 근접배치되는 PDLC(Polymer Dispersed Liquid Crystal)시트(44)를 포함한다.
