Abstract:
A composition for forming an alignment film used during formation of an alignment film with a droplet discharge method includes a solute, a first organic solvent and a second organic solvent. The solute includes an alignment film formation material. The first organic solvent dissolves the solute. The second organic solvent is for controlling surface tension. The first organic solvent includes a solvent having a lowest vapor pressure among all of solvent components in the composition.
