Abstract

PURPOSE: To reduce the production cost by omitting the trimming process by the ammonium fluoride through addfition of the process to form the water repellent film at the panel skirt part after the resist development.
CONSTITUTION: The photo resist is coated on the glass ravel inner surface ofter cleansing the glass panel, and then the photo resist is expoded via the color selection electrode to form the latent image. After this, the development is given to form the prescribed resist film pattern. The water repellent film forming solution is coated at the skirt part on the inner surface of the glass panel and then dried. Then the solution of the light absorbing material is coated on the above mentioned glass panel inner surface, and then the resist film is decomposed with the water solution of the oxidizing agent to recive the development. In this way, the production cost can be reduced.
