Abstract: The present invention relates to a backlight unit of a display device. The backlight unit is structured to have no light guide plate, and can include a reflecting plate, which is arranged on the inner surface of a cover bottom, and which has a sloping surface, and a light-collecting lens, which collects light from an edge light source portion. A light-absorbing pattern is arranged on at least one of an optical sheet, a diffuser plate, and the reflecting plate using such a configuration that the density of arrangement of the light-absorbing pattern is largest on a light-input portion and decreases towards an anti-light-input portion, or using such a configuration that the light-absorbing pattern is formed only on a flat surface of the reflecting plate, near the light-input portion, thereby providing uniform light throughout the entire display panel.
