- the light transmittance at 550 nm was measured with the UV-Vis Spectrometer about the sealing film prepared above, and haze was measured using the haze meter according to JISK7105 standard test method.
- the reference sample is data on the encapsulation film prepared in the same manner as in Example 1, except that the hygroscopic filler and the nonhygroscopic filler were not added.
- the optical properties were obtained at the desired level in the present application, but the moisture permeability was considerably lowered.
- Comparative Example 2 the moisture barrier property was obtained at the desired level in the present application, but the relative luminance was lowered. Indicated.
