Patent attributes
A low-profile edge-lit backlight apparatus includes a light guiding plate which guides light introduced from a side by utilizing total reflection on a light emitting surface as one principal surface and a light reflecting surface as the other principal surface and emits light from the light emitting surface based on surface emitting, and a plurality of white light emission units that emit white light incident on the light guiding plate. The white light emission section includes a light source group of a first light emitting diode to emit first primary color light, a second light emitting diode to emit second primary color light, and a third light emitting diode to emit third primary color light which are arranged in a row, and a color mixing section that generates white light by mixing the first primary color light, the second primary color light, and the third primary color light.
