1. A gate driver of a display device comprising:
an inverter configured to invert a start signal to generate an inverted start signal;
a first driver including a first stage configured to generate a bias gate signal to initialize a light emitting element of each of pixels in the display device in response to the inverted start signal; and
a second driver including a second stage configured to generate a write gate signal to apply data voltages to the pixels in the display device in response to the start signal,
wherein the first driver further receives a first clock signal and a second clock signal whose phase is different than the first clock signal to generate the bias gate signal.
