Illuminating apparatus, backlight assembly and liquid crystal display device having the same

A backlight assembly comprising:

• a lamp for emitting light;
• a light guiding plate for guiding the light;
• and
• a lamp reflector, disposed adjacent to the lamp to partially cover the lamp and receiving the light exited from the lamp, the lamp reflector having a plurality of protrusion portions for reflecting and diffusing the receiving light.

A liquid crystal display device comprising:

• a backlight unit, including:
• a lamp for emitting a first light;
• a light guiding plate for guiding the first light;
• and
• a lamp reflector disposed adjacent to the lamp to partially cover the lamp and receiving the first light exited from the lamp, the lamp reflector having a plurality of protrusion portions for reflecting and diffusing the received first light to generate a second light;
• and
• a display unit for displaying an image in response to the second light exited from the backlight unit, including:
• a lower substrate;
• an upper substrate opposite to the lower substrate;
