イト装置。 In a backlighting device for a transmissive liquid crystal display panel that has an ultraviolet light emitting tube and a phosphor plate and causes the phosphor layer of the phosphor plate to emit light with ultraviolet rays, the thickness of the phosphor layer is determined by the thickness of the phosphor layer. 1. A backlight device for a transmissive liquid crystal display panel, characterized in that the amount of light emitted from each part of the phosphor plate is made uniform by varying the amount of light emitted from each part of the phosphor plate based on the distance from the ultraviolet light emitting tube.
