Abstract:
An electroluminescent display device includes a pixel circuit having transistors, and a gate driving circuit providing an emission signal, a first scan signal, and a second scan signal to the pixel circuit. The gate driving circuit includes an emission signal generating circuit for applying the emission signal to a gate electrode of at least one of the transistors, a first scan signal generating circuit for applying the first scan signal to a gate electrode of at least one of the transistors, and a second scan signal generating circuit for applying the second scan signal to a gate electrode of at least one of the transistors. The first scan signal generating circuit receives the emission signal and a voltage of a QB node of the second scan signal generating circuit, and the emission signal generating circuit and the first scan signal generating circuit include an n-type transistor and a p-type transistor.
