Disclosed are an illumination device to be located immediately below an object to be illuminated, wherein a plurality of point-like light sources are arranged, and a display device provided with the illumination device. Even in a structure wherein the light emitted from point-like light sources is diffused and planarly emitted, in order to provide an illumination device which can uniformly and planarly emit the light without reducing the light intensity at the overlapped portion of the light emitted from the point-like light sources, point-like light sources (LED light sources) each diffusing the light to be emitted in a square-shaped light emission distribution, and an illumination device (LED backlight device) wherein the point-like light sources are arranged in a planar manner so that the square-shaped light emission distributions of the light diffused by the point-like light sources are overlapped in parallel.
An illumination device, comprising:
An LED light source for use as a point-like light source included in an illumination device, the illumination device comprising a plurality of point-like light sources and a mounting substrate on which the point-like light sources are mounted, wherein light emitted from each of the point-like light sources is diffused to have a square-shaped light emission distribution, the LED light source being constituted of an LED package comprising:
