A display device comprising:

• a first display substrate including a first base substrate which is divided into a display portion including pixel regions and a non-display portion including a region other than the display portion, color filters disposed in the pixel regions of the first base substrate, and at least one stepped pattern disposed on the non-display portion of the first base substrate;
• a second display substrate spaced apart from and facing the first display substrate;
• and
• a liquid crystal material layer interposed between the first display substrate and the second display substrate,
• wherein the stepped pattern is formed of the same material as at least one of the color filters,
• wherein the stepped pattern is formed at a density to occupy 20% or more of the non-display portion, and
• wherein a minimum distance between substantially all the stepped patterns and the color filters is about 1.5 mm or more.
