description A backlight unit according to one embodiment comprises: a light source module including a plurality of light sources; a reflective sheet arranged at the rear of the light source module; and a diffusion plate arranged in front of the light source module. The diffusion plate includes at least two areas having different distances to the plurality of light sources. A first gloss of the first area and a second gloss of the second area in the at least two areas are different from each other. Une unité de rétroéclairage selon un mode de réalisation comprend : un module de source de lumière comprenant une pluralité de sources de lumière ; une feuille réfléchissante disposée à l'arrière du module de source de lumière ; et une plaque de diffusion disposée devant le module de source de lumière. La plaque de diffusion comprend au moins deux zones ayant des distances différentes par rapport à la pluralité de sources de lumière. Un premier brillant de la première zone et un second brillant de la seconde zone dans les au moins deux zones sont différents l'un de l'autre. 일 실시예에 따른 백라이트 유닛은, 복수의 광원을 포함하는 광원 모듈; 상기 광원 모듈의 후방에 배치되는 반사 시트; 및 상기 광원 모듈의 전방에 배치되는 확산판;을 포함한다. 상기 확산판은, 상기 복수의 광원과까지 다른 거리를 갖는 적어도 두 영역을 포함한다. 상기 적어도 두 영역 중 제1 영역의 제1 광택도(gloss)와 제2 영역의 제2 광택도는 서로 다르다.
