<P>PROBLEM TO BE SOLVED: To provide an organic electroluminescence light emitting device capable of materializing planar white light at high efficiency and with low cost. <P>SOLUTION: An organic electroluminescence element is formed in a band-shape by using a ribbon-shaped base material 10. On both sides in a width direction of an organic light emitting layer 2 of the element, auxiliary electrodes 5A and 5A for a reflection electrode 1 for reflecting side surface light emitted from a width direction end surface of the organic light emitting layer 2 toward a transparent electrode 3 side are provided. Transparent insulation layers 6L and 6R containing fluorescent material are arranged so as to cover the auxiliary electrodes 5A and 5A for the reflection electrode. Thereby, a small-sized module substrate M of a strip-shape is formed. A plurality of the small-sized module substrates M are disposed in a line on a large-sized mounting substrate so as to make edge portions in the width direction adjacent to each other, thereby increasing an area. <P>COPYRIGHT: (C)2012,JPO&INPIT |
