  • Patent number: 11437407
    Abstract: A display apparatus in which a thin film transistor includes an oxide semiconductor pattern is disclosed. A gate electrode of the thin film transistor can overlap a channel region of the oxide semiconductor pattern. The gate electrode can have a structure in which a hydrogen barrier layer and a low-resistance electrode layer are stacked. A light-emitting device and an encapsulating element can be sequentially stacked on the thin film transistor. A thickness of the hydrogen barrier layer can be determined by a content of hydrogen per unit area of the encapsulating element. Thus, in the display apparatus, the characteristics deterioration of the thin film transistor due to hydrogen diffused from the encapsulating element can be prevented.
