<P>PROBLEM TO BE SOLVED: To provide: a direct lighting device that prevents the occurrence of luminance unevenness or color unevenness; a liquid-crystal display device provided with the same; and electronic equipment. <P>SOLUTION: A backlight unit 50 as a lighting device includes a surface light source, in which a plurality of LEDs 52 as a plurality of light sources are arrayed on a circuit board 51, a diffuser plate 55 as an optical member, which is arranged opposite to the light-emitting side of the surface light source, and a plurality of spacers 53 for maintaining an interval between the surface light source and the diffuser plate 55. The plurality of spacers 53 are arranged on the circuit board 51 so as to have a part in which the arrangement density per unit area is dense and a part in which the arrangement density per unit area is sparse. The part with the dense arrangement density is provided corresponding to the central region of the diffuser plate 55. <P>COPYRIGHT: (C)2010,JPO&INPIT |
