Patent ID: 11945195

Abstract:
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<3 μm  (1)L2a<3 μm  (2) and a distance L1b between the second inorganic barrier layer and the first water-trapping layer satisfies formula (3): L1b≤3 μm  (3) by interposing a water-permeable organic layer therebetween.
