ABSTRACT:
Disclosed is a light emitting display device which provides a light emitting element for controlling the brightness according to the current to each pixel, such as an organic electroluminescent element, and a driving method thereof. The light emitting display device comprises transistors for forming a current mirror, and a pixel structure having first and second scan lines. A time to deselect the second scan signal that is supplied to the second scan line for writing display information on the pixel is earlier than a time to deselect the first scan signal that is supplied to the first scan line for selecting the pixel. As a result, reduction of brightness according to delay of the scan signal is prevented.
