Display apparatus and method of inspecting defects of the same

Provided is a gate driver comprising an inverter inverting a start signal to generate an inverted start signal, a first driver including a first stage generating a bias gate signal to initialize a light emitting element of each of pixels in response to the inverted start signal, and a second driver including a second stage generating a write gate signal to apply data voltages to the pixels in response to the start signal. Accordingly, the gate driver may generate a plurality of gate signals using one start signal. In addition, since the gate driver generates a write gate signal and a bias gate signal using one start signal, a bias operation and a light emitting element initialization operation may be performed in a self-scan period without adding the start signal. Further, a size of the gate driver may be reduced, and accordingly, the gate driver may be efficiently disposed.
