    Abstract: An object of the present invention is to provide a powder mixture containing a polymerizable liquid crystal compound, the powder mixture having a low risk of occurrence of fire due to the flammability of solvent, causing no changes in the appearance due to, for example, precipitation or crystallization of the solute during storage at low temperatures, causing no changes in the composition due to evaporation of solvent during long-term storage or leakage of solvent during long-term storage or transportation, being not viscous and having fluidity unlike nematic liquid crystal compositions, and being easily handled. Another object is to provide a nematic liquid crystal composition, a solution composition, cured products, optical films, and display devices that employ the above-described powder mixture.

    Abstract: To improve technologies for searching for colorant materials.
    A colorant material search method performed by an information processing apparatus 10 includes: training a VAE encoder 3 and a VAE decoder 4, the VAE encoder 3 receiving, as an input, colorant material information expressed in a predetermined notation and outputting latent variables corresponding to the colorant material information on a latent space 5, the VAE decoder 4 receiving, as inputs, any latent variables on the latent space 5 and outputting colorant material information expressed in the predetermined notation; and identifying, based on the VAE encoder 3, the VAE decoder 4, and data regarding a plurality of physical properties of the colorant material, a desired colorant material that satisfies all of the plurality of physical properties.

    Abstract: A retardation plate is formed by laminating at least two retardation plates of a retardation plate 1 and a retardation plate 2, in which at least one of the retardation plate 1 and the retardation plate 2 is formed of a polymer of a polymerizable liquid crystal composition. It is possible to provide a retardation plate imparting a phase difference of ¼ wavelength over a wide wavelength region, a circularly polarizing plate having excellent anti-reflection performance over a wide wavelength region, and a display element or a light-emitting element having excellent visibility.
