Abstract
A thin-film transistor (TFT) array for preventing the light reflected inside a liquid crystal panel from entering a channel layer, while suppressing an increase of stray capacitance. A light shading film and an antireflection film atop source and drain electrodes are made of semiconductor layers and are spaced from each other on a TFT. The reduction in reflected light prevents an increase in an off current and therefore improves the quality of a liquid crystal display.
