  • Publication number: 20250254995
    Abstract: A thin-film transistor array substrate and a display device including the same are discussed. The thin-film transistor array substrate can include a buffer layer disposed over a base substrate and a thin-film transistor. Parasitic capacitance is minimized by minimizing the area where the gate electrode overlaps the conductorization region. The breakdown characteristics of the thin-film transistor are improved by minimizing the overlapping area and improving the thickness uniformity of the gate insulating layer. The resolution and performance of the display device are improved by reducing the size of the thin-film transistor disposed in the display device while improving the characteristics of the thin-film transistor. The process steps and the masks are reduced and the process optimization is achieved. Further, the resistance of the gate electrode is reduced, the switching speed of the thin-film transistor is improved, and the power loss is reduced, thereby contributing to low power consumption.
