1. A display device, comprising a display panel and a circuit connector bonded to the display panel; wherein
the circuit connector comprises a flexible substrate and a bonding structure, an edge of the flexible substrate being provided with a first bonding region;
the bonding structure is disposed in the first bonding region and comprises a first row of pads and a second row of pads, wherein the first row of pads comprise a plurality of first pads arranged along the edge of the flexible substrate, the second row of pads are disposed on a side, proximal to a middle portion of the flexible substrate, of the first row of pads, and the second row of pads comprise a plurality of second pads arranged in a direction in which the plurality of first pads are arranged;
in a first direction, a length of the first pad is less than a length of the second pad, the first direction being a direction in which the first row of pads and the second row of pads are arranged; and
an edge of the display panel is provided with a second bonding region bonded to the first bonding region, wherein orthographic projections of the plurality of first pads onto the display panel fall within the second bonding region, and a third row of pads and a fourth row of pads are distributed in the second bonding region, wherein the third row of pads comprise a plurality of third pads connected to the plurality of first pads in one-to-one correspondence, the fourth row of pads comprise a plurality of fourth pads connected to the plurality of second pads in one-to-one correspondence, and in the first direction, a length of the third pad is equal to a length of the fourth pad.
