Abstract:
1. A liquid crystal display comprising: a gate electrode of a TFT and a gate line formed on a transparent insulating substrate; a gate insulating film covering the gate electrode and gate line; a semiconductor layer formed on the gate insulating film; a source electrode of the TFT, a source line, and a drain electrode of the TFT formed on the semiconductor layer; and a pixel electrode connected to the drain electrode, wherein the semiconductor layer is integrally formed of three portions for the TFT, the three portions including (i) a crossover portion having an elongated shape extending in parallel with a longitudinal direction of the source line and extending to a length that is wider than a structure formed by the source electrode and the drain electrode, (ii) a TFT portion forming an active region for the TFT, and (iii) a connecting portion arranged in parallel with the gate line connecting the crossover portion to the TFT portion, and wherein a part of an entire length of the elongated crossover portion on an opposite side with respect to the connecting portion side is not covered by the source line, and the other part of the entire length of the elongated crossover portion on a same side with respect to the connecting portion side is covered by the source line, and the whole connecting portion is covered by the source electrode and the source line.
