<P>PROBLEM TO BE SOLVED: To provide a backlight module capable of solving a phenomenon of forming an interference pattern. <P>SOLUTION: This backlight module is composed of at least a light guide plate, a reflecting piece, an optical thin film, and a lamp. A plurality of condensing elements is installed on the light emitting surface of the light guide plate, and a plurality of rod-shaped micro light guides is installed on one surface of the optical thin film. Each micro guide is designed so that it has a plurality of peaks, and with the peaks of the micro light guide having different undulations, one of the high peaks or the low peaks is each continuously curved rightward and leftward, or its altitude is continuously undulated upward and downward. Thereby, all of luminous flux is not in a linearly regular state, luminous flux in a continuously curved shape is output, and after passing through a thin film transistor in a liquid crystal panel and a color filter, luminance of a whole output light source is enhanced by preventing the phenomenon of forming the interference pattern when performing display. <P>COPYRIGHT: (C)2008,JPO&INPIT |
