PURPOSE: Polyarylenesulfide is provided to have excellent reflectivity, and transparency, and to have high solubility as solvent, thereby having high suitability to solution process like a spin coating process. CONSTITUTION: An optical unit contains polyarylenesulfide having fluorene structure. The polyarylenesulfide has structure in chemical formula 1. In chemical formula 1, Rm is arylene group, Rn is respectively and independently aryl group or C1-4 alkyl group, a is a number from 0-4, * is bonded material. The polyarylenesulfide has fluorine structure. A composition contains the polyarylenesulfide, and contains one or more kinds selected from organic solvent, surface surfactant, and crosslinking agent. |
