Abstract
PURPOSE:To improve the yield of the product of a fluroescent screen in the forming process of a black matrix, by eliminating the surplus nonluminous ray absorbing substance which sticks on a face portion and an inner and an outer face portion of a panel seal. CONSTITUTION:The matrix of a hardened photoresist is formed on the inner face of a glass panel, and the colloidlike graphite is spreaded on it, and the graphite spreaded coat is dried. Thereafter, the hardened photoresist and the graphite which sticks on it are exfoliated together from the panel by an exfoliate medicine, an a black matrix is obtained on the inner face if the panel. In the next, the sealing face portion of the panel 1 on which the surplus graphite sticks is soaked in an ultrasonic warm water 7. An ultrasonic oscillator 6 is arranged in an ultrasonic water tank, and, for example, generates ultrasonic waves in the oscillation frequency of 28-50KHz, and the graphitic film is exfoliated by cavitation bubbles which are generated by ultrasonic waves, and a glass base body is purified. Thereby, the yield in a matrix forming process is improved.
