Kind Code:
A1
Abstract:
Disclosed is an illumination device in which illuminating light is obtained with reduced power consumption and without local dark patches. An illumination device (12) is provided with: a light source (17) of elongate form; a chassis (14) accommodating the light source (17) and having an aperture (14b) for emitting the light of the light source (17); and an optical member (15a) that is arranged facing the light source (17) and shaped to cover the aperture (14b). In the optical member (15a), a first optical reflective section (50) that reflects light from the light source (17) is formed along an edge section (15e) that is positioned on the side where the end section in the longitudinal direction of the light source (17) is disposed, in such a way that the optical reflectance of the edge section (15e) thereof is relatively larger than the optical reflectance at the periphery of this edge section (15e).
