Abstract
A fluorescent display device capable of preventing variation or flickering of luminescence due to deformation of a mesh section. The fluorescent display device includes mesh-like control electrodes each being made of a material of which the coefficient of average thermal expansion is smaller than that of the glass substrate or a spacer frame at a temperature within the range of from 30.degree. C. to 250.degree. C. and is substantially equal to or larger than that of the glass substrate or the spacer frame at a temperature within a range from 30.degree. C. to the sealing temperature of the fluorescent display device.
