Resist composition for separator formation, separator of EL display device and EL display device

摘要

Provided are a resist composition for separator formation which can be applied for forming separators in the form including a forward taper shape and a reverse taper shape and can be widely used for production of various organic EL displays, and a separator and an EL display device obtained from this resist composition. A composition containing an alkali-soluble resin, an acid generator, a cross-linking agent and a separator pattern shape controlling agent is used as the resist composition for separator formation of an EL display device and the like. The separator pattern shape controlling agent is preferably constituted of a forward taper controlling agent and a reverse taper controlling agent, and these controlling agents can be composed of an amine and an organic acid.
