PURPOSE: To prevent chipping a slurry layer tip part by shortening the length of a linear light source for forming a phosphor layer than that of a light source for forming a light absorption layer when a black stripe type light absorption layer is formed and also exposure is given to phosphor slurry to form a stripe- like phosphor layer.
CONSTITUTION: A black stripe type light absorption layer is provided by applying a photosensitive agent, having a main component of PVA and ammonium dichromate, on a panel 3 inner surface to be dried to form a photosensitive film 10, applying exposure by using a linear light source 4 having a length of Leb via a shadow mask 5, and baking a pattern on the film 10 while corresponding to the mask 5 opening. Next, when a phosphor slurry layer, having a main component of a blue phosphor, PVA, and ammonium dichromate, is formed on the panel 3 inner surface on which the light absorption layer is formed, a linear light source, having a length of Les shorter than that of the said length of Leb, is used via the mask 5 similarly, and a pattern corresponding to the mask 5 opening is baked to form a blue phosphor layer. The similar treatment is performed for green and red.
