<p>PURPOSE:To decrease the OFF current of a TFT in a liquid crystal panel by restraining the light reflected on an opposing substrate from impinging on an a-Si film. CONSTITUTION:In a thin film transistor 3 comprising a gate electrode 5, an a-Si film 6, a drain electrode 7, and a source electrode 8, the source electrode is elongated to form a light shielding part 8a around the a-Si film 6. Since the quantity of backlight transmitting through the TFT substrate is decreased, the quantity of reflected light impinging on the a-Si film 6 is decreased thus decreasing the OFF current of the TFT.</p> |
