In the range of suitably, when the maximum thickness of supporting layer 323 is more than 50 μm with the difference of thickness minima, itself and protecting film
324 combine, and can well support bent area, be provided that again suitable bending angle.
In this implementation, it is also possible to radius of curvature R ＞ 50 μm of each projection in the array of protrusions of supporting layer 323 is set.
In this implementation, by limiting the size of radius of curvature of each projection, it is to avoid due to protruding radius of curvature
The situation that the less projection caused is more sharp-pointed, thus the extruding force produced when bending is not concentrated in the tip of projection, does not allows
Easily crack in projection, thus extend the service life of flexible display apparatus.
