Abstract:
1. A transparent gas barrier film comprising a layer unit A and a layer unit B in this order from a resin substrate, wherein an elastic modulus in the layer unit A gradually increases from a low elastic modulus layer to a high elastic modulus layer from the resin substrate, and an elastic modulus in the layer unit B gradually decreases from a high elastic modulus layer to a low elastic modulus layer from the resin substrate, and further comprising a layer unit C between the layer unit A and the layer unit B and which has an elastic modulus higher than the high elastic modulus layers in either of the layer unit A and the layer unit B, wherein a difference of elastic modulus of adjacent layers is not less than 1 GPa and not more than 20 GPa and each layer in the layer unit A and the layer unit B has a thickness of not less than 1 nm and not more than 10 nm.
