<P>PROBLEM TO BE SOLVED: To provide a backlight unit of a liquid crystal display (LCD) device that can provide high luminance and high color reproduction. <P>SOLUTION: The backlight unit includes a light emitting unit, a light guide plate, a reflection plate and a light scattering unit. The light emitting unit has a passive light emission lamp that generates green light and a self-light emission lamp that generates red and blue light. The light guide plate is disposed between the passive light emission lamp and the self-light emission lamp. The light guide plate mixes the red and blue light emitted from the self-light emission type lamp and guides the mixed light to an upper side thereof. The reflection plate is disposed below the self-light emission lamp. In addition, the light scattering unit is disposed above the passive light emission type lamp. <P>COPYRIGHT: (C)2007,JPO&INPIT |
