Abstract:
A display device comprising:a polarizing device for separating a light from a light-source into first and second polarized rays having mutually perpendicular oscillating planes and emerging the light so that the oscillating plane of one of the first and second polarized ray becomes at the same as that of the other and the first and second polarized rays emerge at an angle between them; a spatial modulator having a plurality of pixels; a periodical structural body having condenser elements corresponding to the pixels of the spatial modulator; and wherein regarding the first and second polarized rays emerging from the polarizing device and passing through a first condenser element, the first polarized ray is made incident to a first pixel and the second polarized ray is made incident to a second pixel; and regarding the first and second polarized rays emerging from the polarizing device and passing through a second condenser element, the first polarized ray is made incident to the second pixel and the second polarized ray is made incident to a third pixel.
