Abstract: A display device includes: a first substrate; a second substrate disposed to oppose the first substrate; a light shielding portion disposed on the first or second substrate and defining a plurality of pixel areas; and a spacer disposed on the light shielding portion between vertically adjacent pixel areas; wherein the spacer has a first interval apart from an upper pixel area and a second interval apart from a lower pixel area from among the vertically adjacent pixel areas, and the first interval differs from the second interval in upper and lower portions of the first or second substrate.
