Abstract
A polarization azimuth compensation layer () is effective in aligning a polarization plane of light obliquely entering an incident-side polarizing plate () with a polarization plane of light entering the incident-side polarizing plate () in a direction of a normal line. A retardation compensation layer () is disposed nearer a liquid crystal layer () than a microlens array () diffracting part of incident light, to compensate a phase difference due to the liquid crystal layer (). Diffracted light caused by the microlens array () and a TFT circuit pattern () enters a polarization azimuth compensation layer (). The polarization azimuth compensation layer () prevents leakage of light by aligning a polarization plane of the diffracted light to be parallel to an absorption axis of an exit-side polarizing plate ().
