ABSTRACT:
An electroluminescent device including an electroluminescent cell, and a switching element connected to the electroluminescent cell. The switching element has an offset area and a unit for applying a voltage to the offset area. According to the electroluminescent device, a higher withstand voltage for the switching element can be obtained, and an adequate flow of drain current in the switching element is insured.
