Patent number: 7948581Abstract: In a liquid crystal display equipped with a side edge backlight device, visualization of “a dot provided to a light guide plate” in the vicinity of the light source while keeping the luminance of the display screen. The shapes and the arrangement of the light diffusing dots (dots) provided to the principal surface of the light guide plate of the backlight device are made different between the area of the principal surface in the vicinity of the light source and the other areas, thereby adjusting the whiteness of the light guide plate in the vicinity of the light source. The plurality of dots formed in the vicinity of the light source are each composed of a first section for diffusing the light propagating the light guide plate, and a second section surrounded by the first section and less capable of diffusing the light, and are disposed in the vicinity of the light source in a zigzag manner.Type: GrantFiled: October 23, 2008Date of Patent: May 24, 2011Assignee: Hitachi Displays, Ltd.Inventors: Hitoshi Taniguchi, Akitoyo Konno
