Abstract:
An image display apparatus comprising pixels each one of which is composed of three subpixels, wherein each pair of the two subpixels is provided with a light source; a first polarizing filter which extracts a component of linearly polarized light from a light of the light source; a liquid crystal which rotates a polarization direction of the linearly polarized light; a polarizing filter which is provided corresponding to one of the subpixels and which extracts a polarized light component in a horizontal direction; a polarizing filter which is provided corresponding to the other of the subpixels and which extracts a polarized light component in a vertical direction; and a control unit which controls the output light amount of the light source and an angle of orientation of the liquid crystal.
