摘要: A moisture barrier laminated film (10) includes: a plastic film (A) having an inorganic barrier layer (A1); a moisture trapping layer (B) containing an alkali component; and a coating layer (C) provided between the inorganic barrier layer (A1) and the moisture trapping layer (B). In the coating layer (C), a moisture permeability at 40° C. and 90%RH is 6.0 × 104 g/m2/day or less, and a storage modulus E′ (at 2π rad/s) in viscoelasticity measurement at 85° C. is 30 MPa or more.

摘要: A water barrier laminate including inorganic barrier and water-trapping layers alternately arranged in order from the side facing the device to the outer side: a first inorganic barrier layer, a first water-trapping layer, a second inorganic barrier layer, a second water-trapping layer and a third inorganic barrier layer. A water-permeable underlying plastic layer is provided on one side of these inorganic barrier layers; a distance L1a between the first water-trapping layer and the first inorganic barrier layer and a distance L2a between the second water-trapping layer and the second barrier satisfy formulas (1) and (2): L1a
