Abstract
A liquid crystal display apparatus includes a first substrate supporting an array of pixel electrodes, defining a display area, and spacer elements having planarized surfaces defining a plane that is parallel to the pixel electrodes and spaced by a distance corresponding to a desired liquid crystal cell gap. Spacers outside of the display area precisely space a covering substrate carrying a transparent counter electrode at the desired cell gap.
