- nx 1 is the refractive index of the first single optical axis optical layer 251 in the x direction
- ny 1 is the refractive index of the first single optical axis optical layer 251 in the y direction
- nz 1 is the first single optical axis
- the refractive index of the optical axis optical layer 251 in the z direction, the z direction is the extension direction of the film thickness of the first single optical axis optical layer 251 (perpendicular to the light incident surface of the first single optical axis optical layer 251)
- the arrangement direction of the metal layers of the second grating layer 240 is parallel to the 0/180 degree direction, and the extending direction of the metal layers of the second grating layer 240 is parallel to the 90/270 degree direction, it is expected that horizontally polarized light can pass through the second grating layer 240
- the equivalent refractive index of the horizontally polarized light passing through the first single optical axis optical layer 251 is no 1
- the equivalent refractive index of the horizontally polarized light passing through the second single optical axis optical layer 252 is ne 2 , because ne 2 > no 1.
