A gas discharge display device comprises upper and lower substrates having anodes and cathodes thereon. An envelope is formed between the upper and lower substrates and includes an ionizable gas therein. A resistance heater element is placed on the lower substrate adjacent the cathode, and at layer of dielectric material is printed over both the cathode and the heater. The heater includes a pair of trimming elements which extend parallel to one another and which may be connected at any one of a plurality of points along their lengths to achieve the desired trimmed resistance value for the heater element.
