Abstract
The embodiment of the invention provides a thin film transistor and a display device, relates to the technical field of display, and can improve the mobility and switching ratio of the thin film transistor at the same time. The thin film transistor includes a grid electrode disposed on a substrate, an active pattern including carbon nanotubes, an auxiliary grid electrode, a source electrode and adrain electrode, the auxiliary grid electrode is electrically connected to the drain electrode; the active pattern comprises a plurality of strip-shaped sub-patterns which extend in a first directionand are arranged at intervals; and in the first direction, one end of each strip-shaped sub-pattern in the active pattern is in contact with the source electrode, and the other end of each strip-shaped sub-pattern in the active pattern is in contact with the drain electrode.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor and a display device. Background technique [0002] In recent years, users' demand for high-quality display panels has gradually increased, and furthermore, the requirements for thin-film transistors (Thin-film transistor, TFT for short) have also become higher and higher. [0003] Currently, Low Temperature Poly-silicon (LTPS for short) or an oxide semiconductor is commonly used as the material of the active layer. However, the TFT using low-temperature polysilicon as the material of the active layer has the problems of poor uniformity and difficulty in achieving a large size. A TFT using an oxide semiconductor as an active layer material has a problem of low mobility. Contents of the invention [0004] Embodiments of the present invention provide a thin film transistor and a display device, which can improve the mobility and switching ratio of the th...
