    Patent number: 6762806
    Abstract: A holder for holding a display device is divided into a first holder (5) and a second holder (6), and a light source housing chamber (10) for housing a light source (1) is also divided so that a work for mounting the light source (1) to the light source housing chamber (10) becomes easy. A first reflector (55) and a second reflector (65) integrally formed with the holder and having a reflecting surface corresponding to a light emitting part of the light source (1) are provided in the light source housing chamber (10), thus a certain space is secured around the light source, the light is efficiently incident to a light guide plate, and a separately formed reflector becomes unnecessary.
