ABSTRACT:
An image display device is disclosed including a metallic support plate carrying, on its front face, a plasma discharge display with an array of adjacent pairs of electrodes and, on its back face, a power supply. The power supply circuit of each pair of adjacent electrodes forms a current loop starting from the power supply and passing through the electrode then the electrode of the pair, the connection end of the electrode being linked to the power supply by means of a transverse electrical conductor placed on the front side of said metallic plate. According to the invention, the transverse conductor linked to the electrode forms a non-zero angle with said pair of electrodes. The differences in inductance between the various current loops of the display are thus reduced such that the differences in luminance between the various discharge regions of the plasma display are reduced.
