SUBSTRATE WITH THIN LINE, MANUFACTURING METHOD THEREOF, ELECTRON SOURCE SUBSTRATE AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress end peeling peculiar to the formation of a thin line by an exposure and development method. SOLUTION: In a substrate with thin lines, the thin lines are formed by a thin line forming process including a step of irradiating light, from above the substrate, to a given region in a photosensitive material applied onto the substrate and a developing step subsequent to the light irradiating step, the thin lines have a narrow portion at a longitudinal end thereof, and the narrow portion has a smaller width shape than a portion adjacent to the narrow portion.
