ABSTRACT:
A liquid crystal display (2) includes a liquid crystal panel (29); a backlight module (20) providing light beams to the liquid crystal panel. The backlight module includes a light guide plate (23) having at least one light incident surface (231), and a light emitting surface (232) adjoining the at least one light incident surface; at least one light source (21) disposed adjacent to the at least one light incident surface; a prism sheet (25) disposed at the light emitting surface for converging light beams; and a first diffuser (26) disposed at the prism sheet for scattering the light beams therethrough. A haze ratio of the first diffuser changes according to the brightness differentia over a brightness distribution of the prism sheet for attaining a substantially uniform surface light beams output.
