[PROBLEMS] After the formation of the cured film, not only does it exhibit high solvent resistance, excellent photo-alignment ability to polymerizable liquid crystal, sufficient heat resistance, and high transparency, but also a glycol system applicable to the production of the overcoat of a color filter during formation of the cured film. Provided are materials that can be dissolved in a solvent, a ketone solvent, or a lactic ester solvent. [Solution] A thermosetting film-forming composition having a photoalignment containing a compound having a photo-alignment property and a hydroxyl group as (A) component, a silicon isocyanate compound as a component (B), a liquid crystal alignment layer formed therefrom, and An optical device provided with a phase difference layer obtained by using. |
