An illuminator for illuminating a liquid crystal panel. A red light separating plate (52R), a green light separating plate (52G), and a blue light separating plate (52B) are alternatingly arranged in line at a pitch w on a substrate (51). Red LEDs (53R) are alternately disposed at the centers between the green and blue light separating plates (52G, 52B) one for each center, green LEDs (53G) are alternately disposed at the centers between the blue and red light separating plates (53B, 52R) one for each center, and blue LEDs (53B) are alternately disposed at the centers between the red and green light separating plates (52R, 52G) one for each center. Un illuminateur pour illuminer un écran à cristaux liquides. Une plaque séparatrice de lumière rouge (52R), une plaque séparatrice de lumière verte (52G), et une plaque séparatrice de lumière bleue (52B) sont disposées de façon alternée en ligne à un espacement w sur un support (51). Les DEL rouges (53R) sont disposées alternativement aux centres entre les plaques séparatrices de lumière bleue et rouge (52G, 52B) une pour chaque centre, les DEL vertes (53G) sont disposées alternativement aux centres entre les plaques séparatrices de lumière bleue et rouge (53B, 53R) une pour chaque centre, et les DEL bleues (53B) sont disposées alternativement aux centres entre les plaques séparatrices de lumière rouge et verte (52R, 52G) une pour chaque centre.
