Abstract
The present invention relates to a light emitting device for preventing cross-talk phenomenon. The light emitting device includes a plurality of pixels and a scan driving circuit. The pixels are formed in cross areas of data lines and scan lines. The scan driving circuit couples at least one scan line to a first voltage source having a first voltage during a first time, couples the scan line to a second voltage source having a second voltage during a second time, and couples the scan line to a third voltage source having a third voltage during a third time. Here, the second voltage is a voltage between the first voltage and the third voltage. The light emitting device discharges the data lines to the same level as data current irrespective of precharge current, and thus cross-talk phenomenon is not occurred to the light emitting device.
