Abstract

광반사기는 광도전판의 광입사 단면에 인접하여 배치된 선형광원을 덮고 있다. 광도전판의 광입사 단면에 근접한 광반사기의 단부사이 간격은 광입사 단면의 두께보다 작게 형성된다. 반면에, 광도전판의 입사 단면과 성형광원 사이에 위치한 광반사기의 광출편 부분은 광입사 단면의 두께 범위내로 배치된다.

Description

휘선이 없는 백라이트 장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제5도는 본 발명의 실시예에 따른 백라이트장치의 단면도이다. 제6도∼제10도는 광원을 포함하는 백라이트 장치의 부분을 나타내는 각각의 본 발명의 실시예에 따른 백라이트장치의 단면도이다.
