<P>PROBLEM TO BE SOLVED: To light a liquid crystal panel by emitting white light which has less number of light of wavelengths other than a wavelength region showing red, green, and blue, and has a sufficient light volume. <P>SOLUTION: Two each of blue CCFL 41B which emit blue light are arranged at both end faces 31a, 31b in the width direction of a light guide plate 31. Ten each of light source units 42 which are provided with red LED 43R and green LED 43G and emit yellow light obtained by mixing red light emitted from the red LED 43R and green light emitted from the green LED 43G are arranged at both end faces 31c, 31d in the longitudinal direction of the light guide plate 31. The light guide plate 31 generates white light by mixing blue light incident from the both end faces 31a, 31b in the width direction and yellow light incident from the both end faces 31c, 31d in the longitudinal direction and emits it from one of main surfaces. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
