Abstract
Panel comprising an array of barrier ribs each having a base resting on a plate and a top in contact with another plate that includes at least two arrays of coplanar electrodes each preferably having a constant width. According to the invention, these barrier ribs have, at their top, a low-permittivity region of thickness greater than 3 μm and less than or equal to one fifth of their total height, which has a mean dielectric permittivity at least three times smaller than the dielectric permittivity of these barrier ribs measured at their base. Thanks to the invention, the confinement of the plasma discharges far from the barrier ribs is substantially improved.
