Claim:
1. An image display apparatus comprising: a display screen which includes pixels arranged in a matrix, each of the pixels including a light-emitting element, a first switching transistor, a second switching transistor, and a driving transistor that supplies a current to the light-emitting element; a first gate signal line disposed for each of rows of the pixels and connected to the first switching transistor; a second gate signal line disposed for each of the rows of the pixels and connected to the second switching transistor; a source signal line disposed for each of columns of the pixels; a first gate driver circuit which applies a control voltage to the first gate signal line and the second gate signal line; a second gate driver circuit which applies a control voltage to the first gate signal line; and a source driver circuit which supplies a video signal to the source signal line, wherein the first gate driver circuit and the second gate driver circuit each have a first mode in which a first control voltage is supplied to one of the first gate signal line and the second gate signal line, the first control voltage being one of an ON voltage, a first OFF voltage, and a second OFF voltage, and a second mode in which a second control voltage is supplied to at least one of the first gate signal line and the second gate signal line, the second control voltage being one of the ON voltage and the first OFF voltage.
