1. A flexible substrate comprising:
an insulating base including a plurality of first strip portions extending along a first direction and aligned along a second direction intersecting the first direction, and a plurality of second strip portions extending along the second direction and aligned along the first direction and a plurality of island-shaped portions located at respective intersections of the first strip portions and the second strip portions;
a plurality of electrical elements overlapping the island-shaped portions, respectively;
a plurality of scanning lines each extending while overlapping the respective first strip portion;
a plurality of signal lines each extending while overlapping the respective second strip portion;
a plurality of connection wiring lines each extending while overlapping the respective second strip portion and the respective signal line;
a scanning line driver to which the connection wiring lines are connected;
a signal line driver to which the signal lines are connected;
a support body supporting the insulating base, the scanning line driver and the signal line driver and including a first side edge, wherein
multiple scanning lines are connected to different connection wiring lines on different island-shaped portion, respectively, and
the scanning line driver and the signal line driver are located on a side of the first side edge.
