1. A display driving device, comprising:
a light emitting unit configured to include a light emitting element;
a driving unit including a memristor and configured to drive the light emitting unit; and
a switching unit including a switching thin-film transistor and configured to determine, depending on a scan voltage, whether to apply a data voltage to the driving unit,
wherein the switching unit is configured to be directly connected to a first node, a gate line for receiving the scan voltage, and a data line for receiving the data voltage, and
wherein the first node is directly connected to each of the light emitting unit, the driving unit, and the switching unit.
