Liquid crystal display apparatus

Abstract

A liquid crystal display apparatus comprises: a color filter base plate having a transparent substrate, a black matrix and a colored film of three primary colors provided on the transparent subsrate, an electrode-carrying base plate provided with electrodes for applying an electric field parallel to the color filter, and a liquid crystal disposed therebetween, wherein a spacer is formed on the black matrix by patterning a resin. The color filter facilitates production of a liquid crystal display apparatus.
