Abstract
An object of the present invention is to provide a liquid crystal display device where there is less inconsistency in the brightness of the backlight due to deterioration in the efficiency of light emission of the light emitting diodes. The present invention provides a liquid crystal display device which stands on a horizontal surface for use having: a liquid crystal display panel; and a backlight provided on the rear of this liquid crystal display panel, and the light emitting source of the above described backlight is formed of a number of light emitting diodes, at least some of which are aligned in the up-down direction of the backlight, and the interval between light emitting diodes aligned at the top of the above described backlight is smaller than the interval between light emitting diodes aligned at the bottom of the above described backlight.
