Abstract

PURPOSE:To prevent corrosion of aluminum of an aluminum pad part and to shorten a stage for the production of a color filter by carrying out patterning of a resin to be used for color filter prior to an etching stage of a glass coating film on the aluminum pad part, and carrying out the etching using a polyimide resin film as a mask. CONSTITUTION:A glass coating film 2 is formed on a substrate 5 having an aluminum pad part 1 formed thereon, and a pattern of a color filter resin is formed on the glass coating film 2. Then, a polyimide resin film 3 and a photoresist film 4 are coated thereon,and the photoresist film 4 is developed and the polyimide resin film 3 is etched. Remaining photoresist film 4 is stripped, and the glass coating film 2 on the aluminum pad part 1 is etched using the polyimide resin film 3 as mask. By this method, corrosion of aluminum in the aluminum pad part is prevented, the production stage is shortened, and the prepn. cost is reduced.
