Abstract

This invention concerns an improvement in manufacturing of color picture tubes wherein photosensitive slurry is applied on the inner surface of a face panel of the tube and dried to form a dried slurry, then a shadow mask is secured to the face panel with a specified gap in between, and ultraviolet rays impinge on the dried slurry layer through a path-refracting lens and apertures of said shadow mask so as to form dots on the inner surface.
