Abstract

See full text

A polarizing plate may have high transmittance characteristics and suppressed reflected light. An optical device may be provided with the polarizing plate. The polarizing plate may have a wire grid structure that includes a transparent substrate and grid-like projection portions arranged on the transparent substrate at a pitch shorter than the wavelength of light in a used bandwidth and extending in a predetermined direction. The grid-like projection portions may each have a reflective layer and a dielectric layer in order from the transparent substrate side. When viewed from the predetermined direction, the reflective layer has may have a step on the side thereof and may have the largest bottom width on the transparent substrate side.
