PURPOSE:To fairly prevent noise without extending a device in an EL display device which displays various picture data by controlling the light emission of each picture element constituted at each intersections of multiple scanning electrodes and multiple data electrodes which are orthogonally intersected with the scanning electrodes. CONSTITUTION:Pulse voltage -VH is applied to the scanning electrode Y1 of a first row, in the same way, pulse voltage VH to the scanning electrode Y2 of a second row, and pulse voltage VM to the data electrode X1 of a first column respectively, at the time of t0-t1. Voltage VH+VM being larger than a threshold value Vt is applied to the picture element Z11 of the first row and the first column, and a EL light emitting layer emits the light. Since voltage having inverted phases each other are applied, vibration of the EL light emitting layer owing to that voltage interferes each other. Therefore, the vibration of whole EL display device is reduced, and noise can be fairly prevented.
