とするエレクトロルミネツセンスパネル装置。 An electroluminescent panel comprising an electroluminescent layer sandwiched between two electrode plates, comprising a piezoelectric layer adhered to one of the electrode plates, and an AC drive applied between the two electrode plates. The electroluminescence panel is characterized by a structure in which vibration of the electroluminescent panel caused by application of the driving electric field is suppressed by applying an alternating current electric field having a phase difference of 180° with respect to the phase of the electric field to the piezoelectric layer. Electroluminescent panel device.
