Abstract
Disclosed is a light transmitting liquid crystal display apparatus used with advantage with a television receiver having a large-sized display not less than 30 inch. A backlight section (3) sending out illuminating light is formed by a plural number of rows made up of many light emitting units (15) arranged on the back surface of a liquid crystal display panel (8). Each light emitting unit includes many LED units (18) mounted on an interconnection substrate (17) and is mounted in this state on a heat dissipating plate (28). A reflecting section (6) for reflecting the light radiated from each LED is formed by a large number of reflective sheet pieces (27), assembled from one heat emitting unit to another, and a reflective plate (26) secured to reflecting plate supports (40) formed on the heat dissipating plate.
