Abstract
Related to is a thin film transistor and a liquid crystal display device. The thin film transistor comprises a substrate, and a conductive laminate and a light-shielding layer that are both arranged on the substrate, wherein the light-shielding layer is located below and directly opposite to the conductive laminate. The thin film transistor is provided therein with the light-shielding layer for shading light from irradiating the conductive laminate, thereby effectively preventing unfavorable influences imposed on the electrical properties of oxides by illumination, and thus improving the electrical properties of the thin film transistor.
