PURPOSE:To prevent generation of wrinkling and blistering by laminating a transparent substrate, color filters, an over coat layer on which a coupling agent is provided, and a transparent electrode in this order. CONSTITUTION:The color filters 6 of three colors; green (G), red (R), blue (B) is formed on the transparent substrate of float glass having 1mm thickness. A photosensitive resin which is epoxy is coated on these color filters 6 so as to attain about 1mum film thickness after drying. After the coating is exposed by UV rays, the unexposed part is developed and removed by an aq. 1% sodium carbonate soln. and the protective layer 2 is formed by patterning to a rectangular shape so as to cover nearly the entire surface of the color filters. The aminosilane coupling agent is thereafter spin-coated by a spinner thereon. The transparent electrode 4 is then formed by sputtering and nickel, aluminum, chromium, and ITO are patterned in this order by the wet process etching used for laminating a thin metallic film 5, by which the electrodes of the display device for a color liquid crystal are formed. The generation of the wrinkling and blistering is thereby prevented. |
