PROBLEM TO BE SOLVED: To prevent the poor printing of barrier ribs formed on an image display device utilizing plasma discharge and prevent the deficiency at the top of the barrier ribs due to polishing. SOLUTION: The image display device comprises a pair of substrates 3, 8 bonded to each other via a predetermined gap for constituting a screen having an enclosed flat space, a dischargeable gas filled in the flat space, an electrode 9 formed on at least one substrate 8 for discharging the gas depending on a voltage applied from the outside and the barrier ribs 10 linearly formed on at least one substrate 8 for partitioning the flat space in rows. The barrier ribs 10 are extended from a display region inside a screen on one substrate 8 to a non-display region outside the screen and the line widths of the barrier ribs 10 are set to be thin on the display region and bold on the non-display region.
