PURPOSE:To attain miniaturization and to reduce number of components by constituting a reflecting plate reflecting a light from a light source to a rear face of a lighted body with an electronic circuit resin board assembling integrally required electronic circuits connecting electrically to the lighted body. CONSTITUTION:A rear face of a liquid crystal display panel 16 is lighted by a light from a light source 14 and a reflected light in the reflecting plate 13 radiates to the rear face. Since the reflecting plate 13 is constituted by the electronic circuit resin board assembling integrally the required electronic circuit 17 connecting electrically to the lighted body 16, a conventional mother board incorporating the electronic circuit is omitted. Thus, number of components is reduced and the space is saved and the assembling efficiency of the back light device is improved and the size is reduced. |
