LIGHT EMITTING DISPLAY DEVICE

Abstract:

Disclosed is a light emitting display device which may block lateral leakage current. The light emitting display device includes electrode patterns arranged under a bank between adjacent subpixels so as to form a vertical channel, the bank covered by the electrode patterns functions as a gate insulating film and thus dielectric polarization occurs therein, and charges move from a common layer having high hole mobility to a common layer having low hole mobility, thereby being capable of preventing lateral leakage current.
