Abstract:
1. An organic semiconductor device comprising: at least p-type and n-type channel organic semiconductor elements each including a wiring line which electrically connects said organic semiconductor elements, the wiring line being made of a material of one of the source and drain electrodes of the p-type channel organic semiconductor element, wherein the source electrode and the drain electrode of the p-type channel organic semiconductor are made of materials having values of work function higher than those of the source electrode and the drain electrode of the n-type channel organic semiconductor respectively, wherein the organic semiconductor layers of the p-type and n-type channel organic semiconductor elements are made of p-type and n-type organic semiconductors respectively, and wherein the source electrode and the drain electrode of the p-type channel organic semiconductor element have values equal or close to an ionization potential of the p-type organic semiconductor layer.
