ABSTRACT:
A wave plate is disclosed which includes a glass plate having a thickness of at least 0.1 mm and at most 5 mm. The glass plate has a plurality of strip-shaped birefringent regions substantially in parallel with a surface of the glass plate. The axial directions of the strip-shaped birefringent regions are the same with one another, and substantially in parallel with the surface of the glass plate. The wave plate has a retardation value of from 80 to 450 nm as measured with incident light having a wavelength of 540 nm.
