Abstract
A sheet-like light source device of side-light type comprising a light-conducting plate, at least one rod-like light source disposed proximate to a light-incident surface, a tubular reflecting member covering portions other than a surface facing the light-conducting plate of the rod-like light source, and a planar reflecting member disposed proximate to a position facing a rear surface of the light-conducting plate. An end portion of the planar reflecting member is projecting out from an end portion of the light-conducting plate within the tubular reflecting member, and the projecting end portion of the planar reflecting member is bent in a parting direction from the rod-like light source. It is possible to prevent degradations in display qualities owing to anomalous emission without degrading the brightness thereof.
