Abstract
A method for fabricating viewing screen ( ) includes the steps of: adding to a black surround paste a ductile metal paste, adding to the black surround paste lead titanate particles, depositing the black surround paste on glass substrate ( ), and heating the black surround paste and glass substrate ( ) to affix the black surround paste to glass substrate ( ), thereby forming black matrix ( ). The ductile metal paste and lead titanate particles are added in amounts sufficient to realize an extent of cracking in black matrix ( ) upon repeated heating to a temperature within a range of 450-600° C. that is significantly less than that exhibited by an unimproved black matrix, which is made only from the material of the black surround paste.
