Abstract:
1. A display device comprising: a substrate having a display area; a plurality of scanning lines and a plurality of data lines, arranged in the display area over the substrate, wherein the data lines extend substantially orthogonally to the scanning lines; a plurality of switching elements each connected to respective one of the scanning lines and to respective one of the data lines, each of the switching elements being a thin film transistor having a semiconductor thin film, an ohmic contact layer, a source electrode and a drain electrode; a plurality of pixel electrodes each connected to respective one of the switching elements; and a plurality of storage capacitance lines disposed substantially in parallel with the data lines, each of the storage capacitance lines having a portion overlapping with a portion of the pixel electrode, the storage capacitance lines being disposed on a plane on which the data lines are disposed and being made of the same material as the data lines, each of the storage capacitance lines including a member formed of a material that is the same as that of the ohmic contact layer.
