  • Patent number: 6680723
    Abstract: Display device designed to prevent surroundings from being adversely affected by noise includes an inner circuit board on which a support frame is mounted in a specific position. A liquid crystal panel is mounted on the support frame and held stationary by a frame. An EL panel for illuminating the liquid crystal panel is mounted behind the liquid crystal panel. An EL circuit board holding an EL driver circuit thereon is bonded to the bottom surface of the EL panel. A shielding plate is mounted on a top surface of the inner circuit board surrounded by the support frame, and is located opposite the EL panel. The shielding plate cuts off noise generated by the EL driver circuit. The EL panel is connected with electrodes on the EL circuit board via lead wires. An electrode on the EL circuit board and an electrode on the circuit board are connected via a contact member. Electric power and control signals are supplied via this contact member.
