Claim:
A liquid crystal television apparatus for receiving a television broadcast and then allowing a corresponding image to be displayed on a screen, the liquid crystal television apparatus comprising: a liquid crystal display panel for displaying the image through the screen of the liquid crystal display; a direct-type backlight device including a diffusion plate arranged on a back of the liquid crystal display panel for irradiating diffused light upon the liquid crystal display panel, a plurality of cold-cathode tubes arranged substantially in parallel on a back of the diffusion plate for irradiating light upon the back of the diffusion plate, and a reflector plate arranged on backs of the cold-cathode tubes for reflecting the light from the cold-cathode tubes toward the diffusion plate; and an inverter section for supplying an alternating current voltage to the direct-type backlight device, the cold-cathode tubes are U-shaped tubes constituted by causing respective two adjacent straight-tubes to be connected at one ends thereof, and the other ends of the respective two adjacent straight-tubes are connected to the inverter section through terminals lined up along one edge of the direct-type backlight device, and are arranged such that their arrangement spaces become wide from a central area toward edge areas; cold-cathode tubes arranged in central area of side by side direction of the cold-cathode tubes are bent into chevron-shapes such that central parts of longitudinal directions of the cold-cathode tubes become crests which is closer to the display surface of the liquid crystal display panel as compared to end parts of the longitudinal directions of the cold-cathode tubes; cold-cathode tubes that are arranged in the outer edge areas of the side by side direction of the cold-cathode tubes are remained straight; and the reflector plate is bent to match with a curvature of the bent cold-cathode tubes, and is formed with a protrusion that is raised up toward the diffusion plate in the central area of the side by side direction of the cold-cathode tubes, the protrusion is raised to a height of one third or less of a distance defined by the diffusion plate and the reflector plate.
