ABSTRACT:
A display device includes a liquid crystal display (LCD) panel, a light emitting diode (LED), and a reflector. The reflector having the first, the second, and the third reflecting surfaces is arranged in the rear of an LCD screen of the LCD panel. The first reflecting surface is arranged parallel to the LCD screen. The light source is arranged between the LCD screen and the LED such that a main axis of light emitted from the LED is parallel to the LCD screen. The second reflecting surface is arranged such that the light is reflected off the second reflecting surface toward the LCD screen. The third reflecting surface is arranged such that the light is reflected off the third reflecting surface toward the first reflecting surface and transmitted to the LCD screen. With this configuration, the amount of the light is less likely to be reduced when the light passes through a light guiding member and the brightness of the LCD screen is increased. Moreover, distances between the first reflecting surface and the LCD screen are about the same in the entire LCD screen, and therefore the brightness of the LCD screen is uniformed.
