LIGHT EMITTING DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME

The present invention relates to a light emitting display device, capable of preventing deterioration in image quality even when data voltages are distributed to data lines using a demultiplexer when a threshold voltage of a driving transistor is compensated in a diode connection method, and to a driving method thereof. According to an embodiment of the present specification, the light emitting display device comprises: a display panel including scan lines, data lines, and a plurality of pixels; a data driving unit for supplying data voltages to p (p is a positive integer) output channels; and a demultiplexer for distributing the data voltages of the p output channels to m (m is a positive integer greater than p) data lines. The demultiplexer includes: a first MUX transistor for connecting a q^th (q is a positive integer satisfying 1
