Abstract
A surface illuminator has a uniform luminance over a large area by using a laser light source, has a wide color reproduction range, and is capable of suppressing a speckle noise. A liquid crystal display uses such a surface illuminator. The surface illuminator includes the laser light source that emits a laser beam; a beam scan section that deflects and scans the laser beam; and a first plate-shaped light guide that causes the laser beam deflected and scanned by the beam scan section to be incident from an end face portion and causes the incident laser beam to emit from a first major surface. Further, the liquid crystal display includes a liquid crystal display panel and the surface illuminator, wherein the surface illuminator is used as a backlight illuminator that lights the liquid crystal display panel from the backside in this liquid crystal display.
