PROBLEM TO BE SOLVED: To provide an illumination device which can precisely control brightness for each area.SOLUTION: An illumination device includes a threshold, a plurality of light sources, a spacer and a diffuser panel. The plurality of light sources and the spacer are surrounded with the threshold. The height of the threshold is made higher than that of the plurality of light sources, and an interval between the threshold and the diffuser panel is made shorter than the height of the threshold. An interval between the threshold and the diffuser panel is made longer than the height of the light source. Thus, it is possible to prevent light leakage from the light source to the outside of the threshold, and precisely control brightness for each area.SELECTED DRAWING: Figure 10 |
