A display apparatus has a scanning line driving circuit and a plurality of scanning lines. The scanning line driving circuit is provided in a region arranged along a side portion on the positive side in the X-axis direction in a display region of a substrate. The scanning line driving circuit includes a plurality of transfer circuits connected to the plurality of scanning lines, respectively. Among the plurality of transfer circuits, the shape of one transfer circuit is different from the shape of another transfer circuit arranged on the negative side of the one transfer circuit in the Y-axis direction. ## Claims ### Claim 1 A display device comprising: a display area; a peripheral area around the display area; a first scanning line and a second scanning line extending to a first direction and provided on the display area; a first shift register provided on the peripheral area and electrically connected to the first scanning line; a second shift register provided on the peripheral area and electrically connected to the second scanning line; a first connection wiring provided on the peripheral area and connecting the first scanning line and the first shift register; a second connection wiring provided on the peripheral area and connecting the second scanning line and the second shift register; and a semiconductor chip mounted on the peripheral area, wherein each of the first scanning line and the second scanning line has a first end and a second end, the first connection wiring is connected to the first end of the first scanning line, the second connection wiring is connected to the second end of the second scanning line, the display area is located between the first end of the first scanning line and the second end of the first scanning line and between the first end of the second scanning line and the second end of the second scanning line, the first scanning line is supplied with a signal from the first shift register, the second scanning line is supplied with a signal from the second shift register, the second scanning line is closer to the semiconductor chip than the first scanning line, the first scanning line is shorter than the second scanning line, in a plan view, the first shift register and the first scanning line are not arranged in the first direction, the second shift register and the second scanning line are not arranged in the first direction, the first shift register and the second scanning line are not arranged in the first direction, the second shift register and the first scanning line are arranged in the first direction, and the second connection wiring is longer than the first connection wiring, in a plan view. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the second connection wiring extends to a second direction crossing the first direction, and the first connection wiring extends to a third direction crossing the first direction and the second direction. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the display area includes a round external form near the first shift register and the second shift register. ### Claim 4 (depends on 1) The display device according to claim 1, wherein the first scanning line is closer to the semiconductor chip than the first shift register and the second shift register. ### Claim 5 (depends on 1) The display device according to claim 1, wherein the first scanning line and the second scanning line are arranged in a direction orthogonal to the first direction. ### Claim 6 (depends on 1) The display device according to claim 1, further comprising: a third shift register arranged in the peripheral area opposed to the first shift register to sandwich the display area; and a fourth shift register arranged in the peripheral area opposed to the second shift register to sandwich the display area, wherein, in a plan view, an interval in the first direction between the second shift register and the fourth shift register is greater than an interval in the first direction between the first shift register and the third shift register. ### Claim 7 (depends on 6) The display device according to claim 6, further comprising: a third connection wiring connecting the second end of the first scanning line and the third shift register; and a fourth connection wiring connecting the first end of the second scanning line and the fourth shift register, wherein the first scanning line is supplied with a signal from the first shift register and the third shift register, and the second scanning line is supplied with a signal from the second shift register and the fourth shift register. ### Claim 8 (depends on 7) The display device according to claim 7, wherein the fourth connection wiring extends to a second direction crossing the first direction, and the third connection wiring extends to a fourth direction crossing the first direction, the second direction and a third direction crossing the first direction and the second direction.
