A display apparatus includes: a partial circuit; a plurality of scanning signal lines; and a plurality of scanning signal connection wirings for connecting the partial circuit and each of the plurality of scanning signal lines. Each of the plurality of scanning signal lines extends in an X-axis direction, and is arranged with a pitch in a Y-axis direction. A plurality of ends respectively included in the plurality of scanning signal connection wirings are connected to the partial circuit, and are arranged in the Y-axis direction. A distance in the Y-axis direction between the respective centers of the two ends adjacent to each other is narrower than the pitch.
