More Information
Summary:The invention is a surface light emitting device and a liquid crystal display device that have wide color reproduction range and small power consumption, said devices (100, 200) being provided with: a laser light source (10); a light path changing element (6) that changes a laser beam (L10) that was input to a light input surface to a linear laser beam (L110) having a straight-line cross-section shape, and outputs said linear laser beam (L110) from a light output surface; a first surface light emitting light guide (5) that by adjusting a spatial intensity distribution in a second plane parallel to a plane (x-y plane) containing a line (y direction) that is the cross-section shape of the linear laser beam, and containing the forward direction (x direction) of the linear laser beam, transforms the linear laser beam (L110) into a surface laser illumination light (L111), and outputs same; an LED light source (9); and a second surface light emitting light guide (4) that is placed as a layer parallel to the first s
