Abstract
First and second columnar spacers are formed on a color filter substrate, and step films are formed on an active matrix substrate in the same step as signal lines. The columnar spacers are formed by proximity exposure, and the step films are formed by being exposed by a lens projection system. In plan view, the step films are disposed inside the columnar spacers. The first columnar spacers are made to be in contact with the regions of the protective film that are higher in elevation with the step films in the active matrix substrate.
