  • Patent number: 7800099
    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.

  • Patent number: 5192995
    Abstract: An improved electric device and manufacturing method for the same are described. The device is for example an IC chip clothed with moulding. In advance of the moulding process, the rear surface of lead frame of the IC chip is cleaned and coated with an antioxidation film made of silicon nitride in order to avoid the oxidation of the lead frame. The antioxidation film ensures the connection of the moulding and the lead frame and protect the IC chip from moisture invaded through cracks or gaps. The coating of silicon nitride is carried out after cleaning the lead frame.
