(d2)) and have the same width (e.g., width (w) in FIG. 6A), and may be arranged in such a way that only the length (e.g., length (l) in FIG. 6a) is changed. For example, there may be a limit to reducing the size of the width of the fine openings 4531 (e.g., the width w in FIG. 6A), so the flexible portion 453 can be formed by adjusting the length while having a relatively same width. It may be advantageous to control the bending characteristics of . According to one embodiment, the openings 4531 arranged in a way that the length gradually increases along the first direction (y-axis direction) may be arranged along the second direction (x-axis direction) in the same manner.
