Abstract
An improved planar color filter structure to reduce defects in the display devices incorporating the color filter structures, including active matrix displays. A color filter substrate has a thicker polyamide black matrix formed thereon and a transparent polyamide layer formed over the black matrix. The transparent layer is exposed through the black matrix and developed to remove the unexposed portions over the black matrix. The resulting surface is substantially planar and facilitates the forming of the remaining layers to form a substantially planar color filter structure.
