A gas barrier laminate having a structure in which a first inorganic barrier layer (3), a water trap layer (5) and a second inorganic barrier layer (9) are formed in this order on a plastic substrate (1) Wherein the moisture trap layer (5) is a layer in which a particulate moisture absorbent having a moisture absorption property with a low humidity and a humidity lower than that of the matrix is dispersed in a matrix made of an ionic polymer, and the moisture trap layer (5) And the second inorganic barrier layer 9, the organic layer 7 serving as a base for forming the second inorganic barrier layer is formed, whereby the barrier property against moisture is excellent and the swelling due to moisture absorption is effective A gas barrier laminate having a suppressed moisture trapping layer and effectively suppressing the efficiency of the moisture trap layer is provided. |
