Abstract
A light emitting display including: a plurality of scan lines adapted to transmit scan signals; a plurality of data lines adapted to transmit a data signal; a plurality of emission control lines adapted to transmit an emission control signal; and a plurality of pixels adapted to emit light in response to the scan signal, the data signal and the emission control signal. At least two pixels receiving the scan signals through different scan lines are connected to one emission control line. With this configuration, a scan driver and a light emitting display including the same have a decreased number of wiring lines provided in a pixel portion, thereby enhancing an aperture ratio, decreasing the number of emission control signals, decreasing the number of components and wiring lines needed for the scan driver, simplifying a fabrication process, and reducing the power consumption of the light emitting display.
