Abstract

The present invention relates to a driving circuit including stages for supplying signals. The respective stages may include: a first LTPO transistor including a first transistor that is a low-temperature polycrystalline silicon thin film transistor (LTPS TFT) and a second transistor that is an oxide TFT; and a second LTPO transistor including a third transistor that is an LTPS TFT and a fourth transistor that is an oxide TFT. A first end of the first LTPO transistor may be connected to a gate of the second LTPO transistor, and voltages of signals corresponding to the respective stages from among the signals may be a voltage at a first end of the second LTPO transistor.
