In a cathode substrate of an FED, spacers lines exclusive for connecting spacers to the ground were necessary besides scan lines and data lines, and a cathode substrate having a three-layer line structure was used in the prior art. In the present invention a cold cathode type flat panel display having a two-layer line structure is realised. The line structure of a cathode substrate 10 of an FED is made into a two-layer structure. Lines of the first layer are bottom electrodes 11 which constitute electron sources and have been used as scan lines, and top electrodes (13, Fig 22) of the second layer have been used as data lines. Moreover, some parts of top electrode bus lines connected to the top electrodes (13) are used as spacer lines, and the top electrode bus lines 16 are divided so as to be made into spacer lines 16'.
