At least one stepped pattern is formed on the non-display portion of the substrate and from the same material as used to form at least one of the color filters. The stepped patterns are formed at an area occupancy density of 20% or more of the non-display portion. A minimum distance is maintained between the stepped patterns and the pixel regions.
