Abstract
Provided are an optical element and an optical device using the optical element to which a manufacturing process for manufacturing a wire-grid structure can be basically applied, and besides, in which a higher polarization contrast ratio than that of a wire-grid element can be obtained. A wobbled wire element in an embodiment has a feature that a periodic structure having a period equal to or larger than a wavelength of an incident light wave is formed in a y direction. In this manner, in a wobbled wire element in a first embodiment, a polarization contrast ratio can be significantly improved.
