Abstract: A backlight unit is provided for a liquid crystal display (LCD) unit in a display device. The backlight unit includes a light guide plate (LGP) and a first light source. The light guide plate has two major surfaces and a first side wall surface between the two major surfaces. The first light source is contact with or in proximity to the first wall surface of the light guide plate and optically coupled with the light guide plate. The light guide plate has a dimension such as length greater than a dimension such as length for the LCD unit. The first light source has a dimension such as length equal to or greater than the dimension such as length for the LCD unit.
