    • A thin direct-type backlight capable of realizing high brightness uniformity is provided by a specific configuration of the direct-type backlight whereby high light beam utilization ratio is maintained while periodical unevenness of the light emitting surface is suppressed. In a direct-type backlight device having a plurality of linear light sources in parallel, a reflection plate and a light diffusion plate, at least one of main surfaces of the light diffusion plate is provided with a prismatic ridges having a sawtooth-shaped cross-section. The apex angle “y” (degree) of the prismatic ridge of the light diffusion plate, the distance “a” (mm) between centers of the adjacent linear light sources, and the distance “b” (mm) from a center of the linear light sources to a surface of the light diffusion plate facing the light source satisfy the relationship of 80×(b/a)+15

    • Provided is a direct-type backlight device having a sufficient luminance in a front direction and capable of suppressing a luminance unevenness on a light emitting plane with a reduced electric power consumption. In the direct-type backlight device having linear light sources 2, a reflecting plate 3 and a light diffusing member 1, a distance (a) between centers of the adjacent two linear light sources is 30 to 65 mm. The light diffusing member 1 has an approximately flat light incident plane 1A and a light outgoing plane 1B on which multiple linear prisms 4 are aligned. The linear prism 4 has two inclined surfaces 4A having an approximately equal tilt angle against a plane which is perpendicular to a thickness direction of the light diffusing member 1.
