Abstract
A thin film transistor device with its leakage current being controlled is provided. With such a thin film transistor device incorporated, a liquid crystal display apparatus presents a high-contrast image at a reduced power consumption. The thin film transistor is formed on an insulating substrate. The gate electrode of the transistor is electrically floating gate electrode, which is capacitance coupled to one or more input electrodes. The liquid crystal display apparatus incorporates the thin film transistor in its switching element and/or driving circuit.
