Abstract: An illumination device is provided which can reduce a movement blur and a tailing phenomenon on a motion picture display while a drop in display brightness is suppressed, and which can suppress power consumption, can be made small and light, and can prolong the lifetime, and a liquid crystal display device using the same is provided. A light source control part of a control circuit synchronizes a latch pulse signal outputted from a gate driver control part to a gate driver, and outputs light emission control signals to respective light source power supply circuits. The respective light source power supply circuits change emission states of cold cathode fluorescent lamps to one of a first to a third emission states on the basis of the inputted light emission control signals, and illuminate an LCD panel from a rear surface of a display area. A first stage emission state is a non-lighting state, a second stage emission state is a maximum lighting state in which maximum lighting brightness is obtained, and a third emission state is an intermediate lighting state in which brightness of about one half of the second stage emission state is obtained.

Abstract: There is provided a liquid crystal display having good display characteristics and a method of driving the same. Pixel data is written in plural pixels on one gate bus line at a top end of a display area at a first point in time on a line sequential basis. At a second point in time, the writing of pixel data in pixels in an upper part of the screen is completed, and writing of pixel data in pixels in a lower part of the screen is started. At a third point in time, the writing of pixel data in the pixels in the lower part of the screen is completed. A fluorescent tube on the upper side of the screen is turned on for a period between a third point in time after the writing of pixel data in the upper part of the screen and a fourth point in time before writing of pixel data for the next frame is started and is turned off in other periods. A fluorescent tube on the lower side of the screen is turned on for a period between a fifth point in time after the writing of pixel data in the lower part of the screen in the preceding frame and a sixth point in time before writing of pixel data in the lower part of the screen is started and is turned off in other periods.
