Claim:
1. An image display apparatus comprising: a display screen including pixels arranged in a matrix and L effective pixel rows, where L is an integer not less than 2, each of the pixels having a light-emitting element; N gate signal lines disposed for each of the L effective pixel rows, where N is an integer not less than two; a source signal line disposed for each pixel column; a first gate driver circuit; a second gate driver circuit; and a source driver circuit which outputs a video signal to the source signal line, wherein the first gate driver circuit and the second gate driver circuit each include N shift register circuits, among the N gate signal lines disposed for each of the L effective pixel rows, each of a gate signal lines has one end connected to the first gate driver circuit and an other end connected to the second gate driver circuit, where a is an integer not less than one and not more than (N−1), an M1th stage of each of a first to Nth ones of the N shift register circuits of the first gate driver circuit is electrically connected to a first to Nth ones of the N gate signal lines in an M1th one of the L effective pixel rows, where M1 is an integer not less than one and not more than L, and an M2th stage of each of a (a+1)th to Nth ones of the N shift register circuits of the second gate driver circuit is electrically connected to a first to ath ones of the N gate signal lines in one of the L effective pixel rows other than an M2th one of the L effective pixel rows, where M2 is an integer not less than one and not more than L×a/N.
