Abstract:
1. A gas-discharge display apparatus comprising a transparent first substrate, a second substrate which is distant from the first substrate by a pre-determined distance and extends parallel to the first substrate, a plurality of discharge spaces which are provided in a gas-tight space which is located between the first and second substrates and is filled with a pre-selected gas, and a plurality of pairs of first and second discharge electrodes each pair of which cooperate with each other to produce a gas discharge in a corresponding one of the discharge spaces, so that a light produced by the gas discharge is observed through the first substrate, the apparatus being characterized by comprising a sheet member including a dielectric core layer comprising a dielectric thick-film having a grid pattern and a pre-determined thickness, a first conductive thick-film layer comprising a plurality of first conductive thick films which are provided on one of opposite surfaces of the grid pattern of the dielectric core layer and extend parallel to each other in one direction of the grid pattern and which function as the first discharge electrodes, respectively, and a second conductive thick-film layer comprising a plurality of second conductive thick-films which are provided on the other surface of the grid pattern of the dielectric core layer and extend parallel to each other in an other direction of the grid pattern and which function as the second discharge electrodes, respectively,
