A method for manufacturing a display including a column spacer for controlling a distance between a switching element substrate and an opposed substrate opposed to the switching element substrate that includes: a bank film formation step for forming a bank film on the switching element substrate; a concave section formation step for selectively etching the bank film to form banks; a spacer formation step for selectively forming the bank film to form the column spacer; and a functional fluid placement step for placing functional fluid in a concave section between the banks.
