That is, the first connection portion 10 is a protruded three-dimensional structure, and the height H1 is greater than the width W1 thereof, which is equivalent to reducing the width W1 of the first connection portion 10 and increasing the height H1 thereof, so that the space occupied by each first connection portion 10 in the driving IC can be effectively reduced on the basis of ensuring the binding area, and more first connection portions 10 can be relatively arranged on the driving IC with a certain space for improving the resolution of the display panel 200.

As shown in fig. 6, since the height H2 of the second connection portion 20 in fig. 6 is smaller than the height H1 of the first connection portion 10, if the height H3 of the first conductive adhesive 30 is set to be greater than the height H2 of the second connection portion 20, the first conductive adhesive 30 may overflow the second connection portion 20, which may cause a short circuit of the second connection portion 20, and it is further required to ensure that the height H3 of the first conductive adhesive 30 is smaller than the height H2 of the second connection portion 20, so that a partial region may not have the first conductive adhesive 30, and it is ensured that the first conductive adhesive 30 does not overflow the connection portion and extends to other regions to cause a short circuit.

It can be understood that: on the one hand, in the display panel 200 provided by this embodiment, in the direction X in which the first connection portions 10 or the second connection portions 20 are arranged, the width of the first conductive paste 30 is smaller than the width of the first connection portions 10 and smaller than the width of the second connection portions 20, so as to reduce the width of the first conductive paste 30, thereby reducing the occupied area of each first conductive paste 30 on the binding region, and thus more first connection portions 10 and second connection portions 20 can be arranged in the limited binding region to satisfy the high resolution of the display panel 200. In another aspect, in the display panel 200 provided in the present embodiment, in the direction X in which the first connection portions 10 or the second connection portions 20 are arranged, the width of the first insulating layer 40 is smaller than the width of the first connection portions 10 and smaller than the width of the second connection portions 20. The width of the first insulating layer 40 is reduced to reduce the occupied area of the binding region by each first insulating layer 40, so that more first connection parts 10 and second connection parts 20 can be disposed in the limited binding region to satisfy the high resolution of the display panel 200. In another aspect, in the display panel 200 provided in this embodiment, in the direction X in which the first connection portions 10 or the second connection portions 20 are arranged, the width of the first conductive paste 30 is smaller than the width of the first connection portions 10 and smaller than the width of the second connection portions 20; and the width of the first insulating layer 40 is smaller than the width of the first connection portion 10 and smaller than the width of the second connection portion 20. Meanwhile, the widths of the first conductive paste 30 and the first insulating layer 40 are reduced, so that the occupied area of the bonding area per first conductive paste 30 and per first insulating layer 40 is reduced, and thus more first connection parts 10 and second connection parts 20 can be arranged in the limited bonding area to meet the high resolution of the display panel 200. However, the present invention does not specifically limit the width of the first conductive adhesive 30 and the first insulating layer 40 in the first direction X, the first conductive adhesive 30 may ensure the electrical connection between the first conductive part 10 and the second conductive part 20, and the first insulating layer 40 may prevent the short circuit between the adjacent connection parts.
