Abstract
A screen includes a polarization layer having plural acicular particles provided with their major axes oriented nearly in the same direction on a substrate, and has polarization selectivity of reflecting light in one polarization direction and absorbing light in the other polarization direction of two polarization directions orthogonal to each other on a plane perpendicular to incident light.
Claims6
A reflecting screen comprising:
- a substrate;
- and
- a polarization layer having plural acicular particles provided with major axis directions oriented nearly in the same direction on the substrate;
- and
- a member between the substrate and the polarization layer,
- wherein light reflectance with respect to a first polarized light in a first polarization state is higher than light reflectance with respect to a second polarized light in a second polarization state different from the first polarization state,
- wherein the member is configured to reflect the first polarized light and the polarization layer is configured to absorb the second polarized light, and
- wherein the polarization layer is a first layer of the screen in a view of a user side.
