Abstract: Provided are a thin film transistor, a display device, and a thin film transistor manufacturing method, in which variation in characteristics is small. The present invention is provided with: a gate electrode formed on a substrate; a gate insulation film formed so as to cover the gate electrode; a semiconductor layer which is formed on the upper side of the gate insulation film and which includes a polysilicon layer disposed, in a plan view, inside a region defined by the gate electrode; an etching stopper layer disposed on the upper side of the polysilicon layer; and a source electrode and a drain electrode provided on the semiconductor layer so as to be separated from each other, wherein the polysilicon layer has first and second regions which are not covered with the etching stopper layer, and a part of the source electrode exists above the first region and a part of the drain electrode exists above the second region.

Abstract: A three-terminal capacitor includes a main body having a cylindrical or substantially cylindrical shape extending in a first direction and including first and second inner electrodes alternately laminated together with dielectric layers interposed therebetween, a pair of first outer electrodes on two end surfaces of the main body in the first direction and electrically connected to the first inner electrodes, and a second outer electrode electrically connected to the second inner electrodes. The main body includes a projecting portion projecting in a direction perpendicular or substantially perpendicular to the first direction at a position between the pair of first outer electrodes. The second outer electrode is provided on one surface of the projecting portion viewable when viewed in the first direction.

Abstract: In the present invention, a target receiver terminal information storage unit stores a plurality of target receiver terminal numbers corresponding to a plurality of target receiver terminals. The control unit determines idle/busy information stored with a corresponding terminal number as a pair, selects a target receiver terminal number according to a predetermined priority, and outputs the selected number. A sender can thereby automatically call up an appropriate target receiver terminal by dialing a registered receiver identification number. The control unit uses connection information as well as idle/busy information as a determining element in selecting a number. Therefore, a registered number conversion service user can distribute calls to a plurality of target receiver terminals. Besides, the user can select a plurality of target receiver terminal numbers through an inquiry to a switching unit about the idle/busy state without storing idle/busy information or connection information in the storage unit.
