CIRCUIT BOARD, DISPLAY DEVICE, AND PROCESS FOR PRODUCTION OF CIRCUIT BOARD |
摘要 |
<p>The present invention provides a highly reliable circuit board that includes TFTs a semiconductor layer of which is formed from an oxide semiconductor; and low-resistance aluminum wirings. The circuit board of the present invention includes an oxide semiconductor layer; source wirings; and drain wirings, wherein each of the source wirings and the drain wirings includes a portion in contact with the semiconductor layer, portions of the source wirings in contact with the semiconductor layer and respective portions of the drain wirings in contact with the semiconductor layer spacedly facing each other, and the source wirings and the drain wirings are formed by stacking a layer formed from a metal other than aluminum and a layer containing aluminum.</p> |
