Abstract
A stacked body for a flexible display device comprises a substrate layer and an antistatic layer. The antistatic layer side surface of the stacked body has a contact angle of water of 100° or more. A ratio of the contact angle of water of the antistatic layer side surface after a steel wool test, rubbing the surface with a #0000 steel wool for 2500 strokes with a load of 9.8 N, is 0.6 or higher compared with the contact angle before the steel wool test. A surface resistance of the antistatic layer side surface of the stacked body is 9×10Ω/□ or less, and the surface resistance of the antistatic layer side surface of the stacked body after an eraser test, rubbing the surface with a 6 mm diameter eraser, for 2500 strokes, applying a load of 9.8 N, is 9×10Ω/□ or less.
