Abstract
PURPOSE:To restrict transformation of Sn at low temperatures and prevent the function as a back plate from deteriorating by forming the back plate with Sn containing a small amount of time-constant additive. CONSTITUTION:An EL panel is obtained by forming layers with electron beam deposition or the like on a transparent glass substrate 1 with said layers comprising: a transparent electrode 3 made of ITO, an insulation layer 4 made of Al2O3 and Ta2O5, a luminescent layer 5 made of ZnS doped with Mn, an insulation layer 6 made of Y2O3 and Ta2O5, and a back plate 7 made of Sn added with a small amount of additive. The back plate 7 is constituted with Sn containing at least one element out of Bi, Sb, Pb, Au, Cd, Ag, As, and In by a small amount. As a result, the electrode 7 is prevented from deteriorating due to transformation even if dielectric breakdown occurs between the electrodes 3 and 7 as the electrode comes to a self-restoring type breakdown mode without expanding a breakdown point.
