<P>PROBLEM TO BE SOLVED: To provide a backlight device and a liquid crystal display which can suppress the thickness, and suppress the weight even if upsized. <P>SOLUTION: The backlight device includes an LED chip substrate on which red LED chips to emit red light, green LED chips to emit green light and blue LED chips to emit green light are arranged in plural numbers by an optional arraying method, a diffusion part which is disposed above the LED chip substrate and diffuses each light emitted from each LED chip, a light amount detecting part to detect the light amount based on the light emitted from the LED chip substrate, and an adjusting part to adjust an electric current supplied to the LED chip substrate. Such constitution allows the cost down of the liquid crystal display. <P>COPYRIGHT: (C)2007,JPO&INPIT |
