Abstract:
A video display device includes a light guide unit for guiding outgoing light from a light source unit to a pixel area of a display device. The light guide unit includes a rod integrator having an input opening through which the outgoing light from the light source unit enters and an output opening provided on a side opposite to the input opening, and a light shielding plate provided between the input opening of the rod integrator and the light source unit. The light shielding plate has a plurality of types of openings for passing the outgoing light from the light source unit to the rod integrator. The light shielding plate is arranged in a state where one of the plurality of types of openings, which has a shape similar to that of the input opening of the rod integrator which is actually mounted, is aligned with the input opening.
