Photochromic-dichroic articles are provided, which include a substrate having a first surface, a fixed-polarized layer over the first surface of the substrate, and a photochromic-dichroic layer over the first surface of the substrate. The fixed-polarized layer optionally includes a fixed-colorant and has a first polarization axis. The photochromic-dichroic layer includes a photochromic-dichroic compound that is laterally aligned within the photochromic-dichroic layer, and which defines a second polarization axis. The first polarization axis and the second polarization axis are oriented relative to each other at an angle of greater than 0 and less than or equal to 90. The photochromic-dichroic articles can provide, for example, increased optical density and/or increased kinetics when exposed to a given amount of actinic radiation.
