An organic electroluminescence display has data, gate, and signal lines arranged on a substrate. Pixel regions are defined by the gate and signal lines. Switching elements provided in the pixel regions are electrically connected to the signal lines and the gate lines. Switching blocks open and close an electrical connection between the signal lines and the pixels. A driving unit drives the switching elements by supplying scanning signals to the gate lines. The driving unit also supplies a first control signal before the scanning signals are supplied and a second control signal when the scanning signals are supplied. The second control signal makes the switching blocks sequentially conductive, during which time image signals are supplied to the data lines. The first control signal permits the signal lines to be set at a predetermined voltage.
