摘要：
A display comprises means for changing the polarization of light, such as a liquid crystal cell, and has a means for analyzing light on one side thereof. A means for diffusing light is disposed between the cell and the analyzing means. This arrangement results in a higher contrast ratio for the display than for the prior art arrangement having the analyzing means disposed between the cell and the diffusing means.
