Disclosed is a member for display apparatus used in a display apparatus comprising a back panel 1 on which electron sources are provided and a front panel 2 that are disposed to oppose the back panel 1 via spacers 3, said member comprising a ceramic that has a Young's modulus (E) of not lower than 120 GPa, a specific rigidity (E/) of not lower than 4010⁹ cm, a coefficient of linear expansion of 7.510^-6 to 1010^-6/ C. in a temperature range from ordinary temperature to 400 C., and a void-occupying area ratio of 6% or less. This member allows it to prevent the accuracy of the apparatus from lowering and cracks from occurring.
