This is because fiber-reinforced plastic film does not have many pores on its surface, but many fibers are exposed on the cut side, which creates many holes and gaps.
This is because moisture may enter from here and degrade the performance of the display device. By sealing this side surface with resin, it is possible to prevent moisture from entering and improve its reliability. In FIG. 3, only the side surfaces of the fiber-reinforced plastic film substrate 41 are covered with resin, but the resin may be extended to the sides of the sealing material 48, or the entire outer surface of the fiber-reinforced plastic film substrate may be covered with resin. It may be covered with
