BACKLIGHT DEVICE AND IMAGE DISPLAY DEVICE USING BACKLIGHT DEVICE

摘要

A backlight device for a liquid crystal display device is provided with: a base chassis; a backlight unit formed from a plurality of backlight blocks on the base chassis; a plurality of LEDs that discharge light in a direction parallel to a light radiating surface of the backlight unit; LED substrates to which the LEDs are attached; and an LED cover unit that is attached to the LED substrate and on which a pattern that adjusts the amount of light output by the light radiating surface is printed. The plurality of LEDs is attached to the LED substrate such that the light output direction is in the opposite direction for every other LED. One connector for supplying electricity to the LED substrate is provided for each LED substrate. The spacing for each LED substrate in the Y-axis direction is selected such that the brightness of the display device at the upper and lower edge parts becomes darker by a prescribed proportion. The brightness of the LEDs at the left and right edge parts of the display device is darker than the other LEDs.
