Abstract
The present invention relates to a pixel circuit, a display device using the same, and a method of manufacturing the same. A pixel circuit according to the present technology is a pixel circuit including a light-emitting diode and can include a light-emitting diode, the pixel circuit including a switching transistor connected to a node at which a scan line and a signal line intersect each other, a driving transistor which receives a data voltage in the signal line through the switching transistor and converts the data voltage to a current to be supplied to the light-emitting diode, and a storage capacitor which maintains a voltage applied by the switching transistor, wherein at least one of the driving transistor and the storage capacitor includes a layer formed of a ferroelectric. The present technology can provide a pixel circuit using a programmable driving TFT or programmable storage capacitor using a ferroelectric instead of a compensation circuit for compensating a critical voltage of the conventional current drive-based display circuit.
