Abstract
A display panel includes a base layer, a first thin film transistor on the base layer, a second thin film transistor electrically coupled to the first thin film transistor, and a light emitting element electrically coupled to the second thin film transistor. The first thin film transistor includes a first semiconductor pattern on the base layer, a first barrier pattern on the first semiconductor pattern and including a gallium (Ga) oxide and a zinc (Zn) oxide, and a first control electrode on the first barrier pattern and overlapping the first semiconductor pattern. Accordingly, a signal transmission speed of the display panel may be improved, and electrical characteristics and reliability of the thin film transistor included in the display panel may be improved.
