Abstract
A moisture-absorption sheet includes a small fraction of an organic polymer having a high weight-averaged molecular weight and a large fraction of particles of a moisture absorbing substance. In spite of the high content of moisture-absorbing material, the moisture-absorption sheet is not susceptible to crack formation and disintegration, and may have a high porosity. Due to these properties, the moisture-absorption sheet is particularly useful in an organic electroluminescent device.
