THIN FILM TRANSISTOR AND LIQUID CRYSTAL DISPLAY AND ELECTRONIC EQUIPMENT MADE USING THE SAME

摘要

In a TFT which is provided with a channel area opposed to gate electrodes with a gate insulating film inbetween, a source-drain area connected to the channel area, a source-drain wiring layer which is electrically connected to the source-drain area, and a gate wiring layer which is electrically connected to the gate electrodes on the surface side of a substrate, at least one component composed of a conductive or semiconductor film is provided with an expanded section for radiating heat which is formed by expanding the component itself for improving the heat radiating efficiency of the component.
