PROBLEM TO BE SOLVED: To obtain a light source, capable of easily obtaining white light of high luminance and red light of high saturation by LEDs as well as to obtain a novel illumination device and liquid crystal display using this light source. SOLUTION: A first LED (LEDb) which emits a monochromatic light of blue and a second LED (LEDa) which emits a monochromatic light of red are used. Green light is formed through wavelength conversion (a fluorescent filter 2) from the blue light. The white light is obtained by additive mixture of colors, which formulate the blue light and green light formed by the first LED and the red light from the second LED. |
