Abstract
According to one embodiment, disclosed is a pattern forming method including preparing a second dispersion by adding a second protective group and second solvent to fine particles including a first protective group whose surface polarity is close to that of the substrate, the fine particles containing, at least on the surface thereof, a material selected from Al, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Y, Zr, Sn, Mo, Ta, W, Au, Ag, Pd, Cu, Pt, and an oxide thereof, modifying the fine particles including the first protective group with the second protective group, adding a viscosity adjustment agent to the dispersion containing the fine particles to prepare a coating solution, and applying the coating solution on the substrate to form a fine particle layer thereon.
