The present invention relates to a luminance enhancement optical substrate to be used in a flat panel display having a flat panel type light source which comprises: a substrate; a light input surface on one side of the substrate; an uneven light output surface on the other side of the substrate; and a long prism array arranged in parallel to the light output surface. A prism has a horizontally changed section. Therefore, the luminance enhancement optical substrate has a surface structure which enhances luminance and reduces interference-fringes. 본 발명은 평판형 광원을 갖는 평판 디스플레이에 사용할 휘도보강용 광학기판에 관한 것으로, 기판; 기판 한쪽의 광입력면; 기판 반대쪽의 요철형 광출력면; 및 광출력면에 나란히 배치된 기다란 프리즘 배열을 포함하고, 프리즘은 수평으로 변형된 구간을 갖는다.
