Document Type and Number:
Japanese Patent JP5684370
Kind Code:
B2
Abstract:
An organic EL light emitting device (100) comprises a transparent substrate (1), a transparent electrode film (2) formed on the substrate (1), a positive electrode contact portion (4) in contact with a part of the transparent electrode film (2) and electrically connected therewith, an insulating layer (7) formed on the transparent electrode film (2) such that the an insulating layer (7) covers a portion excluding a light emitting part, an organic light emitting layer (8) formed on the transparent electrode film (2) and on the insulating layer (7), a negative electrode film (9) formed on the organic light emitting layer (8), a negative electrode contact portion (5) in contact with at least a part of the negative electrode film (9) and electrically connected therewith, and a protective layer (3) for separating and electrically insulating the positive electrode contact portion (4) and the transparent electrode film (2) from the negative electrode contact portion (5). The transparent electrode film (2) is formed without a gap across an area including areas where the protective layer (3), the positive electrode contact portion (4), the negative electrode contact portion (5), the insulating layer (7), the organic light emitting layer (8) and the negative electrode film (9) are formed.
