Abstract:

To provide excellent positional accuracy by applying non-photosensitive fluorescent paste to the whole surface of a base plate having ribs, applying photosensitive paste to the whole surface of the base plate, exposing and developing the base plate by using a specified photo mask, and removing and burning the photosensitive paste and fluorescent paste on unnecessary parts.

Fluorescent paste (red) is contact-printed on a base plate having stripe-shaped ribs and dried, and photosensitive paste is printed solidly, laminated on the florescent paste, dried, positioned to the base plate applied with paste by using a photo mask 50, and exposed by a high-pressure mercury lamp. After that, it is developed with water, photosensitive paste and fluorescent paste on parts other than the exposed part are removed, and fluorescent paste (red) is patterned. Fluorescent paste (green and blue) are patterned by the same processing after being positioned by using the photo mask 50.
