A wiring circuit board is supported on the back surface of a light-guide plate and the wiring circuit board is inclined in a predetermined direction relative to the panel surface of a liquid crystal panel or to an arrangement position of a holding case. As a result, a substrate terminal is also arranged at an inclined position in the predetermined direction. A connector is mounted on a circuit board. Connector terminals of the connector are elastically deformable at least in a direction contacting the substrate terminal. These connector terminals are conductively connected to a plurality of mounting terminals, which are exposed and extended on the surface of the circuit board, respectively.
