ABSTRACT:
The present invention aims to solve problems involved in the formation of a conductive or insulating layer in a pattern form by photolithography, i.e., an environmental problem associated with handling a solvent and a problem associated with wastewater treatment in the development with an aqueous alkaline solution. A method for forming a conductive layer (an anode bus 3) or an insulating layer (a barrier 1) on a glass substrate by photolithography using a photosensitive slurry solution prepared by mixing a low-melting glass powder as a binder and a conductive or insulating powder into a PVA-based, water-soluble photosensitive solution, wherein the content of B.sub.2 O.sub.3 component in the whole low-melting glass powder is closely regulated to not more than 6% by weight. This enables coating without gelation of PVA. Unlike the conventional photolithography using a solvent type photosensitive slurry, the method of the present invention can solve the environmental problem associated with handling a solvent and the problem associated with wastewater treatment in the development with an aqueous alkaline solution.
