Abstract
In a wire grid polarization element, a second light transmissing substrate is disposed on first surface side of the first light transmissing substrate on which a metallic wire grid is formed, and on the first surface of the first substrate, a recessed portion is formed in a region overlapping a region where the wire grid is formed in plan view. For this reason, it is possible to secure a space in which the wire grid is disposed between the first substrate and the second substrate without using a spacer. In addition, at the time of sealing the space in which the wire grid is disposed, the first substrate and the second substrate are bonded to each other on the outer side of the recessed portion.
