Abstract
A gate driving circuit and a light emitting display apparatus including the same has a simplified circuit that outputs a stable emission control signal. The gate driving circuit includes an emission control shift register including a plurality of emission control stages that each respectively supply an emission control signal to one of a plurality of emission control lines, each emission control line connected to at least one pixel of a plurality of pixels in a light emitting display panel. For an emission control line, when at least one of first input signal and the second input signal has a first voltage level, an emission control stage outputs the emission control signal having a gate-off voltage level, and when both of the first input signal and the second input signal have a second voltage level, the corresponding emission control signal has a gate-on voltage level.
