Summary: | The present invention relates to a backlight unit of a display device. The backlight unit is structured to have no light guide plate, and includes a reflecting plate (210), which is arranged on the inner surface of a cover bottom (310), and which has a sloping surface, and a light-collecting lens (129), which collects light from an edge light source portion (128). A light-absorbing pattern (410, 420, 430) is arranged on at least one of an optical sheet (250), a diffuser plate (240), and the reflecting plate (210) using such a configuration that the density of arrangement of the light-absorbing pattern (420, 430) 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 (410) is formed only on a flat surface of the reflecting plate (210), near the light-input portion, thereby providing uniform light throughout the entire display panel. |
