Abstract:
An ink composition for forming an electron transport region in a light emitting element includes inorganic nanoparticles and a first solvent having a Hansen solubility parameter hydrogen bonding term (δH) value of 5 or less in order to increase dispersion stability of the inorganic nanoparticles, and thereby prevent or reduce nozzle clogging in the head of an inkjet printing device.
