A display device includes a source line for supplying a display signal, a display pixel electrode, and a TFT for switching an electrical connection between the source line and the pixel electrode. The TFT includes a source electrode electrically connected to the source line, a drain electrode electrically connected to the pixel electrode, and a gate electrode for controlling an electrical connection between the source electrode and the drain electrode. A first auxiliary capacitor electrode and a second auxiliary capacitor electrode are connected to the drain electrode and respective connection portions between the drain electrode and the auxiliary capacitor electrodes are formed of a semiconductor material.
