Abstract
An amorphous-silicon TFT (thin-film-transistor) in an LCD device has a larger channel length at both the edge portions of the channel of the TFT compared to the central portion of the channel by forming chamfers at the corners of the source and drain electrodes. The larger channel length at both the edge portions reduces the leakage current caused by the turned-around light incident onto the channel.
