Document Type and Number:
Japanese Patent JP4166455
Kind Code:
B2
Abstract:
A light emitting device capable of reducing degradation caused by dispersion of impurities such as moisture, oxygen, an alkaline metal, and an alkaline earth metal is provided. Specifically, a flexible light emitting device with an OLED formed on a plastic substrate is provided. In a light emitting device using a substrate, a circular polarizing plate has a single layer or two or more layers of barrier films formed of a compound or compounds selected from AlNXOY, AlXNY, and Al2O3, which is (are) capable of preventing oxygen and moisture from seeping into an organic light emitting layer of an OLED as well as preventing an alkaline metal, an alkaline earth metal, and other impurities from penetrating an active layer of a TFT.
