Abstract
A spacer is constructed of a stacked colored layers constituting color filters and is disposed in such a position as to exhibit a high dielectric breakdown strength on an active matrix substrate. A display performance is enhanced because of using no plastic beads, and insulation can be maintained. When the spacer assumes an inversely tapered shape, a contact position of the spacer can be freely selected because of forming no conductive layer on side surfaces.
