Patent abstract
A backlight unit for an LCD device produces a more uniform brightness by reducing or preventing bright lines occurring at the location of each LED device. The backlight unit includes a plurality of light guide plates which are arranged to overlap with an incident portion of adjacent light guide plate to at least partially cover the LED array. Accordingly, the backlight unit can prevent the generation of bright lines and hot spots caused when the light guide plate does not cover the LED array. As a result, the LCD device may improve images of uniform brightness.
