Display device

A display apparatus, comprising:

• a plurality of display elements arranged in a matrix in a display region of a panel substrate;
• a plurality of signal lines connected for each row or each column of the plurality of display elements;
• and
• a grayscale voltage output unit provided on one side of the panel substrate to output, to each one of the plurality of signal lines, a grayscale voltage based on a video signal, wherein
• one signal line including a disconnection location in the plurality of signal lines is divided into a first signal line portion located at a side of the one side with respect to the disconnection location and a second signal line portion from the disconnection location to a terminating end,
• a terminating end side with the terminating end of the second signal line portion is connected to the grayscale voltage output unit via a spare wiring, and
• the grayscale voltage output unit:
• outputs, for the one signal line, a first grayscale voltage to the first signal line portion, the first grayscale voltage being corrected based on a position of the disconnection location and a wiring resistance of the one signal line so as to be smaller in absolute value than the grayscale voltage to be output to the one signal line;
• and
• outputs, for the one signal line, a second grayscale voltage to the second signal line portion, the second grayscale voltage being obtained by correcting the grayscale voltage to be output to the one signal line based on the position of the disconnection location, a wiring resistance of the one signal line, and a wiring resistance of the spare wiring.
