Abstract
A display device includes a plurality of cold cathode tubes that define linear light sources and are arranged in an aligned state in a backlight device. A direction that is perpendicular or substantially perpendicular to a surface S along the direction of alignment of the cold cathode tubes is set as the illumination direction. The cold cathode tubes are supported in two kinds of postures whose axes intersect with each other. A first inclined cold cathode tube and a second inclined cold cathode tube are arranged in postures that incline the axis of each relative to the direction of illumination. The overall distribution of light intensity can be expanded by the amount of the relative inclination angles of the first inclined cold cathode tube and the second inclined cold cathode tube.
