Abstract (in Japanese) (See Japanese page) 
(in English) Recently, flexible displays are receiving a lot of attention, and the demands of flexible displays are expected to increase in the future. For the metal interconnection in foldable displays, bending resistance is necessary in addition to heat resistance and low electrical resistivity. However, Mo interconnection, which is used as a gate electrode of LTPS TFT, is easily disconnected by bending test with a radius of 1 mm. In this study, we report the bending resistance of Al-Nd alloy films, which have been used as gate electrodes of a-Si TFT, and clarify the adaptability of Al-2.0 or 4.0 at% Nd alloy films to the foldable displays.
