Abstract
A stacked display has the different color layers (20r), (20g), (20b) ordered with respect to the wavelength-dependency of the lens focus so that there is better focus of the colors on the display layers that modulate those colors. The optical system (30), (32) can be designed to have a wavelength-dependent focus that matches the position of each of the light modulating layers.
