Abstract: An EL display apparatus includes: gate driver ICs (i. e., gate driver circuits); a plurality of pixels; gate signal lines each transmit a selection voltage for selecting a pixel from the pixels and non-selection voltage for placing a pixel in a non-selection state; and TCON. The pixels each include: a driving transistor; an EL element; a first switching transistor; and a second switching transistor. The gate driver ICs each include scanning and outputting buffer circuits which are connected to TCON to which an output signal of each of the scanning and outputting buffer circuits is inputted.
