A light reflecting material having a reflecting layer comprising barium sulfate, titanium dioxide and a binder resin. When the light reflecting material of the present invention is used as a reflector of a lighting panel of edge light type, it efficiently causes light to enter into a light conducting plate and hence high brightness of the lighting panel can be obtained. High brightness is also obtained when it is used as a light reflecting material of backlight systems and illumination signboards.
