  • Publication number: 20110001893
    Abstract: An illumination device 12 according to the present invention includes a linear light source 17, a chassis 14 that houses the linear light source 17, and a spacer 41 that is provided between the linear light source 17 and the chassis 14 so as to separate the linear light source 17 from the chassis 14. The spacer 41 is arranged under the linear light source 17 on the chassis 14 when viewed in plan. Since the spacer 41 is provided between the linear light source 17 and the chassis 14 so as to maintain a distance therebetween over a predetermined distance, the spacer 41 does not overlap the linear light source 17. Therefore, dark areas are less likely to be present on the linear light source 17 and thus uniformity of illumination luminance distribution can be ensured.
