In a device encapsulation method, an organic EL device is formed on a substrate. An encapsulation cap is placed on the substrate to surround the device and thereafter an end face of the cap is welded on at least the substrate. A device package is also disclosed.

In a filter for an organic EL panel formed by a quarter-wave layer (&lgr;/4 plate), a polarizing layer and an anti-glare layer, the polarization of the polarizing layer is between 50% and 70%, and the haze value of the anti-glare layer is between 5% and 15%.

Organic EL panel and filter for same

An organic EL element includes a light-transmitting glass substrate, an organic electroluminescence (EL) layer, a frame, a sealing cap, and an adhesive. The organic EL layer is formed on an element formation region of the substrate. The frame is formed on the substrate to surround the element formation region. The frame has a flat upper surface that has absorbed a three-dimensional shape on a surface of the substrate. The sealing cap is to be fixed to an upper surface of the frame. The adhesive adheres the frame and the sealing cap to each other. The adhesive is set at a temperature lower than a heat resistant temperature of the organic EL layer. A method of manufacturing the organic EL element is also disclosed.

Organic EL element and method of manufacturing the same

An organic electro-luminescent display panel and a method of manufacturing same are provided which are capable of reliably holding a hygroscopic agent in its sealing cap in a uniform and thin state and of being easily manufactured and of being configured to be of a thin-profile type, without sacrificing light-emitting characteristics and display contrast. The organic electro-luminescent display panel is constructed of a transparent insulating substrate, an organic electro-luminescent device formed on the transparent insulating substrate and a sealing cap to make up sealed space hermetically containing the organic electro-luminescent device in cooperation with the insulating substrate. The hygroscopic agent is enclosed hermetically in the sealed space and is of a powder or grain type, which is sandwiched between the sealing cap and an air-permeable sheet.
