ABSTRACT:
In a glass viewing screen for a color-picture-reproducing device, the phosphor areas deposited on the inside of the glass viewing screen are surrounded by a sealing-glass matrix. The matrix is made of a sealing glass that shrinks upon thermal crystallization so that the sealing glass may be deposited by screen printing.
