| titleOfInvention | Direct type backlight device |
| abstract | SUMMARY OF THE INVENTION The present invention provides a direct backlight device for a display device with high brightness while suppressing tube deviation efficiently without using an optical member that has been subjected to special processing. In the direct backlight device of the present invention, a reflecting member, a plurality of linear light sources, and an optical member group are arranged in this order, and satisfy the following conditions (i) to (iii). (Iii) The plurality of linear light sources are arranged so that the longitudinal directions of the respective linear light sources are parallel to each other. (Ii) The haze value based on JISK7136 (2000) measured by injecting light from the surface of the linear light source side in the optical member closest to the said linear light source in the said optical member group is 99.0% or less. (Iii) There is a prism sheet in the optical member group, and the prism sheet is formed with a plurality of convex shapes extending in one direction on a surface on the side opposite to the linear light source side, and the plurality of convex longitudinal directions are parallel to each other. , The plural convex longitudinal directions are parallel to the plural linear light sources. (Iii) The said reflector is 60 degrees glossiness of 5 or less measured based on JISK7105 (1981) of the said linear light source side surface. (Iii) In the plurality of linear light sources, when the distance between the centers of adjacent linear light sources is L and the distance from the center of the linear light sources to the optical member closest to the linear light source is H, the following equation (1) ) Satisfying () is 45 ° ≤θ≤70 °. θ = tan −1 ((L / 2) / H). Formula (1) |
