<P>PROBLEM TO BE SOLVED: To provide a surface lighting device with an array of light-emitting elements corresponding to a plurality of colors including at least red, green, and blue colors, that is, a plurality of LEDs (light-emitting diodes) emitting primary colors as a surface light source, and also to provide a liquid crystal display achieving high brightness even with a large screen by being equipped with the surface lighting device. <P>SOLUTION: The surface lighting device is at least provided with: a surface light source consisting of light-emitting elements corresponding to a plurality of colors including at least the three primary colors of light; a reflecting plate arranged between the light-emitting elements; a base plate on which the light-emitting elements and the reflecting plate are installed; and a diffusing plate located above the light-emitting elements and the reflecting plate. A covering rate of the base plate by the reflecting plate is improved, and the light-emitting elements are aligned, or an irradiation angle to get a maximum light volume of the light-emitting element corresponding to at least one color, is set in accordance with intervals between the diffusing plate and the base plate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
