A grid polarizing element has a structure that can prevent deteriorations due to an oxidization gas. The grid polarizing element is preferably used to polarize light in a ultraviolet light region. The grid polarizing element includes a transparent substrate and a grid layer disposed on the transparent substrate. The grid layer has a plurality of linear portions, and is shaped like a stripe. The grid layer is covered with a gas blocking layer to block the oxidization gas generated by the ultraviolet light such as ozone and active oxygen species. The gas blocking layer is transparent at a wavelength of the light to be polarized. |
