Abstract
A light source device capable of suppressing generation of color unevenness, and a display device using the same are provided. The light source deviceis provided with a plurality of excitation light sourceswhich are arranged at prescribed intervals D on a substrateand emit blue light, and a phosphor layerwhich converts part of the blue light emitted from the excitation light sources into red light and green light and arranged at a distance from the excitation light sourcesto oppose the substrate. Fluctuation of intensity of each color light due to nonuniform application of the phosphor layer is difficult to occur as compared with a configuration in the past where the phosphor layer is formed adjacent to each excitation light source.
