1. A display apparatus including a plurality of pixels arranged in a matrix, each of the plurality of pixels including:

  • an optical element of current-driven type;

    a drive circuit of non-complementing type which drives said optical element based on a luminance signal and self-corrects a drive operation thereof;

    a correction circuit which controls on and off of the self-correction of said drive circuit; and

    a holding circuit which holds the luminance signal used in the drive operation, wherein said drive circuit generates a luminance signal which is corrected based on a predetermined signal delivered temporarily and an operation threshold value of said drive circuit, and self-corrects the drive operation by driving said optical element based on the corrected luminance signal.
