Abstract
A display device including a plurality of light sources spaced apart from one another, a refracting plate disposed over the plurality of light sources, and first and second refracting surfaces formed at both surfaces of the refracting plate to allow light emitted from the light sources to be scattered plural times by passing through the refracting plate, the first and second refracting surfaces having different shapes from each other. With the display device, light emitted from the light sources can be uniformly diffused, whereby high brightness uniformity can be accomplished even at positions relatively close to the light source, resulting in a reduction in a thickness of the display device.
