a plurality of pixel structures, disposed at the active region of the base;
a plurality of data lines, electrically connected to the plurality of pixel structures and arranged in a first direction;
a plurality of scan line groups, wherein each of the scan line groups comprises a plurality of scan lines, the plurality of scan lines are arranged in a second direction, the first direction and the second direction are staggered, and the plurality of scan lines of the plurality of scan line groups are electrically connected to the plurality of pixel structures;
a plurality of transfer line groups, wherein each of the transfer line groups comprises a plurality of transfer lines, and the transfer lines are arranged in the first direction and are electrically connected to the plurality of scan lines of a corresponding scan line group;
a plurality of connection terminal groups, disposed on the first peripheral region of the base, wherein each of the connection terminal groups comprises a plurality of connection terminals;
a plurality of bridge line groups, disposed on the base and are structurally separated from each other, wherein each of the bridge line groups is electrically connected to a corresponding transfer line group and a corresponding connection terminal group; and
an insulation layer, wherein the each of the bridge line groups comprises a plurality of first bridge lines extending in the first direction and a plurality of second bridge lines extending in the second direction, the insulation layer is disposed between the plurality of first bridge lines and the plurality of second bridge lines of the each of the bridge line groups, the plurality of second bridge lines of the each of the bridge line groups are electrically connected to the plurality of first bridge lines through a plurality of first contact windows of the insulation layer, and the plurality of transfer lines of the each of the transfer line groups are electrically connected to the plurality of first bridge lines of a corresponding bridge line group through a plurality of second contact windows of the insulation layer,
wherein the connection terminal group, the bridge line group, and the transfer line group corresponding to each other are electrically connected through the plurality of first contact windows and the plurality of second contact windows of the insulation layer, two of the plurality of first contact windows and the plurality of second contact windows with a furthest distance in the first direction have a first distance in-between, and a length of each of the first bridge lines in the bridge line group is greater than or equal to the first distance,
wherein the plurality of connection terminals of the connection terminal group comprise a first connection terminal to an n-th connection terminal sequentially arranged in the first direction, where n is a positive integer greater than or equal to 2, the plurality of transfer lines of the transfer line group comprise a first transfer line to an n-th transfer line respectively electrically connected to the first connection terminal to the n-th connection terminal, and an arrangement sequence of the first connection terminal to the n-th connection terminal in the first direction is different from an arrangement sequence of the first transfer line to the n-th transfer line in the first direction.
