Claim 0:
1. A polarizing plate having a wire grid structure, comprising:
a transparent substrate; and
a plurality of grid-like projection portions that are arranged on the transparent substrate at a pitch shorter than a wavelength of light in a used bandwidth, and extend in a predetermined direction,
wherein the plurality of grid-like projection portions each having a reflective layer, an absorption layer, and a dielectric layer in order from the transparent substrate side,
wherein the reflective layer, when viewed in the predetermined direction, comprises:
a rectangle portion having a bottom on the transparent substrate side, and
a shape with a first width changing in a continuous manner,

wherein the bottom of the rectangle portion has a second width that is largest,
wherein the dielectric layer and the absorption layer, when viewed in the predetermined direction, are rectangular and have a third width that is the same as the second width of the bottom of the rectangle portion of the reflective layer, and
wherein the shape of the reflective layer is formed of a curved line.
