Abstract: An optical device (100) includes laser light sources (111 to 113), polarization films (121 to 123), and a stacked wave plate (130). The laser light sources (111 to 113) respectively output light of a different wavelength. The stacked wave plate (130) includes multiple wave plates (131 to 133) and induces a phase difference on polarization components of transmitted light. The polarization films (121 to 123) adjust the polarization direction of the light such that an angle between polarization directions of the light emitted by the laser light sources (111 to 113) and input to the stacked wave plate (130) becomes an angle that corrects an orientation angle difference that occurs at the stacked wave plate (130), consequent to differences in the wavelength of the light.

Abstract: There is provided a cured-film formation composition that forms a cured film having excellent photoreaction efficiency and solvent resistance, and high adhesion, an orientation material for photo-alignment, and a retardation material formed with the orientation material. The cured-film formation composition comprises a component (A) that is a compound having a photo-aligning group and one substituent selected from a hydroxy group, a carboxy group, and an amino group; a component (B) that is a hydrophilic polymer having one or more substituents selected from a hydroxy group, a carboxy group, and an amino group; and a component (C) that is a cross-linking agent that reacts with the component (A) and the component (B) and reacts at a temperature lower than a sublimation temperature of the component (A), wherein when the component (B) is an acrylic polymer, the cured-film formation composition further comprises a component (E) that is an adhesion enhancing component. The cross-linking agent of the component (C) may be more hydrophilic than the component (A). The orientation material is formed by forming a cured film with the cured-film formation composition and utilizing photo-alignment technique. The retardation material is obtained by applying a polymerizable liquid crystal on the orientation material and curing it.
