Abstract
A backlight unit including a plurality of light-emitting device units with varying arrangement intervals such that the light-emitting device units are more densely arranged at edges of a base plate than at center thereof, and a liquid crystal display (LCD) apparatus employing the same. The backlight unit is designed to prevent creation of dark portions on corners due to a shortage in an amount of light, thereby providing improved brightness uniformity.
