A polarization azimuth compensation layer (31) is effective in aligning a polarization plane of light obliquely entering an incident-side polarizing plate (30) with a polarization plane of light entering the incident-side polarizing plate (30) in a direction of a normal line. A retardation compensation layer (41) is disposed nearer a liquid crystal layer (34) than a microlens array (40) diffracting part of incident light, to compensate a phase difference due to the liquid crystal layer (34). Diffracted light caused by the microlens array (40) and a TFT circuit pattern (46) enters a polarization azimuth compensation layer (36). The polarization azimuth compensation layer (36) 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 (37).
