Liquid crystal display having a pixel region with a source electrode of at least a high-melting-point metal layer

An active matrix liquid crystal display device comprising:

• first and second substrates;
• a liquid crystal layer disposed between the first and second substrates;
• plural image signal lines and scan signal lines formed on the first substrate;
• and
• plural drain terminals connected to the image signal lines, and plural gate terminals connected to the scan signal lines;
• wherein respective pixel regions are formed by adjacent image signal lines and adjacent scan signal lines;
• wherein the respective pixel regions have at least one of a semiconductor layer, a pixel electrode, a counter electrode, and a source electrode which has a high-melting-point metal layer and an aluminum layer formed on the high-melting-point metal layer;
• wherein the high-melting-point layer enables connection of the semiconductor layer and the pixel electrode, the semiconductor layer and the pixel electrode being arranged so that at least a portion of the pixel electrode is arranged at a level which is lower than a lowest level of the semiconductor layer, and the pixel electrode is formed between the high-melting-point metal layer and the first substrate;
• and
• wherein a part of the scan signal lines positioned between the pixel regions and the gate terminal is covered by an ITO layer electrically connected to the counter electrode.
