Abstract
A polarizing element or polarizing plate comprising a layer having photoactive molecules and a layer containing dichroic molecules formed in contact with said layer, which can easily be produced without a stretching procedure so as to have a complicated pattern, a curved surface or a large area; and a process for producing said polarizing element or polarizing plate which is characterized by irradiating a layer having photoactive molecules on a substrate with linear polarized light, and then forming a dichroic molecular layer on the irradiated layer.

A polarizing element or polarizing plate having a first layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C, non-aromatic C.dbd.N and non-aromatic N.dbd.N and a second layer containing dichroic molecules formed in contact with said first layer.
A process for producing a polarizing element or polarizing plate, characterized by irradiating a layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C, non-aromatic C.dbd.N and non-aromatic N.dbd.N on a substrate with linear polarized light, and then forming a layer containing dichroic molecules on the photoactive molecular layer.
A gradation display polarizing element or polarizing plate having a first layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C, non-aromatic C.dbd.N and non-aromatic N.dbd.N and a second layer containing dichroic molecules formed in contact with said first layer having photoactive molecules.
A process for producing a gradation display polarizing element or polarizing plate, characterized by irradiating a layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C , non-aromatic C.dbd.N and non-aromatic N.dbd.N on a substrate with linear polarized light through a mask composed of portions different in depth of color, and then forming a layer containing dichroic molecules on the photoactive molecular layer.
A multi-axial polarizing element or polarizing plate having a layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C, non-aromatic C.dbd.N and non-aromatic N.dbd.N and a layer containing dichroic molecules formed in contact with the former layer.
A process for producing a multi-axial polarizing element or polarizing plate, characterized by irradiating a layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C, non-aromatic C.dbd.N and non-aromatic N.dbd.N on a substrate with two or more kinds of linear polarized lights having different axes of rotation, and then forming a layer containing dichroic molecules on the photoactive molecular layer.
A stereoscopic display polarizing element or polarizing plate having a first layer having photoactive molecules containing at least one double bond selected from non-aromatic C.dbd.C, non-aromatic C.dbd.N and non-aromatic N.dbd.N and a second layer containing dichroic molecules formed in contact with said first layer having photoactive molecules.
