Abstract
PURPOSE: To obtain a luminous screen which excels in the white color uniformity by making more sudden the effective diameter distribution of the red luminous element than that the green and blue luminous elements featuring nearly identical effective diameter and the brightness to each other.
CONSTITUTION: Shadow mask 4 is attached to face panel 1, and photo resist 3 is exposed from three kinds of light source positions. The light control filter 8 which controls the effective distribution from the center to the circumference part is used in common to green and blue, and another different filter featuring a lower transmittance of the circumference to the center than filter 8 is used for exposure of the red luminous element. After exposure, the development is given with the graphite suspension applied. Then a treatment is given with 10% H2O2 and pure water to form the stripe-type black matrix opening part 14. Thus, effective diameter W is decided for each luminous element. In this method, no partial coloring is produced, ensuring the uniform white color over the entire screen.
