    Abstract: An optically anisotropic film exhibiting reverse wavelength dispersibility and an Nz factor of about 0.50 (0.40 to 0.60), is formed of a lyotropic liquid crystalline composition containing colorable rod-like and plate-like compounds, where a measurement to obtain an ultraviolet-visible absorption spectrum by applying linearly polarized light is carried out by changing light direction and assuming that an absorbance at a maximum absorption wavelength in a wavelength range of 230 to 400 nm of the rod-like compound is highest at a first direction, and of the plate-like compound is highest at a second direction, the first direction and the second direction are orthogonal to each other, the maximum absorption wavelength in a wavelength range of 230 to 400 nm of the rod-like compound is smaller than that of the plate-like compound, and NzP represented by Expression (N) NzP = (nxP - nzP)/(nxP - nyP) of the plate-like compound is negative.

    Abstract: A sensor including a light-receiving element; and an optical element that includes near infrared absorbing dichroic substance. The optical element has an absorption axis with respect to near infrared light in an in-plane direction. When linearly polarized light of near infrared light orthogonal to the absorption axis is radiated from a normal direction of the optical element and from a direction inclined by 45° from the normal direction at an azimuthal angle orthogonal to the absorption axis, an absorbance during the radiation from the direction inclined by 45° from the normal direction is more than an absorbance during the radiation from the normal direction.
