Title:
ORGANIC EL ELEMENT, ORGANIC EL ELEMENT PROTECTION FILM AND METHOD FOR MANUFACTURING THE ORGANIC EL ELEMENT PROTECTION FILM
Document Type and Number:
WIPO Patent Application WO2006022273
Kind Code:
A3
Abstract:
An organic EL element, especially a top emission type, having an increased effective emission quantity per consumption power is provided by providing a protection film, which has a microlens array which can be integrally formed with a cap, can concentrate light emission from both planes of an organic EL layer on one plane and has a high transparency. The organic EL element includes the protection film; an organic EL light emitting diode (OLED) including a transparent electrode film, the organic EL layer and a counter electrode layer; a board whereupon the OLED is mounted; and the cap for covering the OLED. On the outer plane or inner plane of the cap or on the front side of the transparent electrode film, the microlens array made of, for instance, a silicone resin, is provided, preferably a light reflecting plane is provided on the board, and more preferably, the protection film includes a silica film and an organic fluorine polymeric film containing silicon.
