Abstract:
1. A luminescent display device, comprising: a substrate; a first thin-film transistor above the substrate, the first thin-film transistor including: a second thin-film transistor above the substrate, the second thin-film transistor including: an interlayer insulating film on the gate electrode of the first thin-film transistor and the gate electrode of the second thin-film transistor; a first capacitor electrode on the interlayer insulating film above the gate electrode of the first thin-film transistor; and a luminescent element configured to be driven by a driver to produce luminescence, the driver including the first thin-film transistor and the second thin-film transistor, wherein the first capacitor electrode and the gate electrode of the first thin-film transistor constitute a first capacitor, and the first capacitor electrode is not connected to the source electrode and the drain electrode of the first thin-film transistor, the first thin-film transistor is a switching transistor that determines a timing of supplying a driving current to the luminescent element, and the first capacitor initializes a second capacitor that sets a value of the driving current.
