An organic EL display device (10) is provided with first and second drivers (1, 2), a multitude of switching circuits (US, DS) and a control circuit (5). The first and second drivers are provided with a multitude of output terminals (P). The multitude of switching circuits alternately connect n-number of the output terminal(s) of the first driver (1) (n is an integer of 1 or more) with one and the other of driving lines, which are of the 2n number of organic EL elements and are divided into two, and alternately connect n-number of the output terminal(s) of the second driver (2) with the remaining n-number of the other and the one of the driving lines. The control circuit (5) controls the multitude of switching circuits to switch at the same time by generating a control signal by m frame(s) (m is an integer of 1 or more) or by m horizontal line(s). Thus, brightness variation and brightness nonuniformity can be reduced. ® KIPO & WIPO 2007
