Abstract:
1. A level shifter, comprising: a first transistor including a gate electrode receiving a first driving voltage, and a source electrode receiving an input signal through an input terminal; a second transistor including a source electrode receiving the first driving voltage, and a drain electrode electrically connected to a drain electrode of the first transistor through a first node; a third transistor including a source electrode receiving a second driving voltage, a drain electrode electrically connected to a gate electrode of the second transistor through a second node, and a gate electrode receiving the input signal; a fourth transistor including a source electrode receiving the first driving voltage, a gate electrode electrically connected to the drain electrode of the first transistor through the first node, and a drain electrode electrically connected to the drain electrode of the third transistor through the second node; a fifth transistor including a source electrode electrically connected to the drain electrode of the second transistor, a gate electrode electrically connected to the first node, and a drain electrode electrically connected to the gate electrode; and an inverter that inverts a signal outputted from the second node to apply the inverted signal to an output terminal.
