Abstract
There is provided a liquid crystal display device which can be lengthened in life and in which the area of its so-called a picture frame can be narrowed. The liquid crystal display device includes a liquid crystal display panel having a display part in its central portion except its periphery; and a backlight disposed on a back side of the liquid crystal display panel. The backlight includes a discharge tube having electrodes at at least its opposite ends, and the electrodes are disposed at the exterior of the discharge tube. The opposite end portions of the discharge tube where the respective electrodes are disposed are positioned to be superposed on the periphery of the liquid crystal display panel, and are bent with an angle with respect to the central axis of the discharge tube.
