Rear projection device

A rear projection device having a body cabinet, comprising:

• an analog signal processing circuit board;
• a shield case low in profile with a circuit board housed therein;
• an optical unit;
• a power-source circuit board for a lamp serving as a light source of the optical unit;
• all constituent members described being disposed on top of a bottom face of the body cabinet;
• wherein the analog signal processing circuit board is disposed on one end of the bottom face, on one side of the right and left sides of the optical unit, in a substantially horizontal posture;
• the power-source circuit board for the light-source lamp is disposed on the one end of the bottom face, on the other side of the right and left sides of the optical unit, in a substantially horizontal posture;
• and
• the shield case is provided in close proximity to the optical unit, and between the optical unit, and the analog signal processing circuit board so as to be substantially erect, running along a front-to-rear direction while being disposed in a region where the analog signal processing circuit board is linearly connected in a plan view to the power-source circuit board for the light-source lamp in such a way as to provide complete blockage therebetween.
