Abstract

A light emitting display device includes a pixel circuit unit, a data distribution unit, a plurality of signal generating units, a unit light emitting diode, and a dummy opening. The pixel circuit unit is configured to generate an output current. The data distribution unit is configured to apply a data voltage to the pixel circuit unit through a data line. The plurality of signal generating units are respectively configured to apply a scan signal and a light emission control signal to the pixel circuit unit through a plurality of signal lines. The unit light emitting diode is configured to receive the output current of the pixel circuit unit and is attached to the pixel circuit unit. The dummy opening is formed in the region where the pixel circuit unit, the data distribution unit, and a plurality of signal generating units are not positioned.
