Method for forming graft polymerization layer, electronic device, and electronic apparatus

A method for forming a graft polymerization layer, comprising:

• (a) forming a polymerization initiation layer on a base material by linking the base material with a linking group of a polymerization initiator that contains the linking group and a chemical bond activated by a polymerization catalyst, and forming a stabilizing layer containing a stabilizing agent having no chemical bond activated by the polymerization catalyst but having the linking group that links the stabilizing agent to the base material in a region on the base material outside the region for forming the polymerization initiation layer;
• and
• (b) separately supplying to at least a partial region on the polymerization initiation layer a first solution containing the polymerization catalyst and a second solution containing a first monomer having a group polymerizable to the chemical bond and a first side chain by use of a droplet discharge method so as to form the graft polymerization layer constituted of a first graft polymer containing more than one first monomer linearly linked to the chemical bond.
