To provide a liquid crystal display achieving uniformalization of display luminance from a viewpoint of a backlight.

The liquid crystal display device includes a backlight, which in turn consists of a cold cathode ray tube CLT arranged on a surface facing the liquid crystal panel, and a chassis CS supporting the cold cathode ray tube CLT. The cold cathode ray tube is arranged so that a separation distance from the chassis at an end part of a side with high voltage impressed is larger than that at an end part of a side with low voltage impressed.
