Abstract: In a backlight apparatus for an LCD, a plurality of bar-shaped first LED light sources are arranged on the reflective plate to laterally emit light. A plurality of light shades are arranged above the first light sources. A transparent plate is placed above the light shades. Scattering patterns are formed in the bottom of the transparent plate in positions corresponding to the light shades. A bar-shaped second LED light source is arranged at a side of the transparent plate to emit light into the transparent plate. The light source arranged at the side of the transparent plate prevents the formation of dark areas as a problem in the prior art, thereby enhancing the entire uniformity of light. Then, the backlight apparatus can be maintained thin even when applied to a large-sized LCD.
