A display device in which a display area and a non-display area are defined, the display device including a wiring substrate, the wiring substrate including: a base substrate; a first thin film transistor disposed on the base substrate, located in the non-display area, and including a first gate pattern, a first semiconductor pattern disposed on the first gate pattern, a first source pattern disposed on the first semiconductor pattern, and a first drain pattern disposed on the first semiconductor pattern and spaced apart from the first source pattern; and a second thin film transistor disposed on the base substrate and located in the display area. A first channel width of the first thin film transistor is greater than a first overlap length of the first gate pattern, the first semiconductor pattern, and the first drain pattern.

Wiring substrate and display device including the same which suppress deterioration of thin film transistor

A thin film transistor is provided. A thin film transistor according to an exemplary embodiment of the present invention includes: a substrate; a gate line disposed on the substrate and including a gate electrode; a semiconductor layer disposed on the substrate and including at least a portion overlapping the gate electrode; a gate insulating layer disposed between the gate line and the semiconductor layer; and a source electrode and a drain electrode disposed on the substrate and facing each other over a channel region of the semiconductor layer. The gate insulating layer includes a first region and a second region, the first region corresponds to the channel region of the semiconductor layer, the first region is made of a first material, the second region is made of a second material, and the first material and the second material have different atomic number ratios of carbon and silicon.
