LIGHT EMITTING DEVICE AND MANUFACTURING METHOD OF LIGHT EMITTING DEVICE

摘要

A dielectric layer (170) faces a surface of alight transmissive electrode (120) opposite to a surface facing an organic functional layer (110). Then, a light transmissive substrate (140) faces a surface of the dielectric layer (170) opposite to a surface facing the light transmissive electrode (120). At least apart of an optical angle change unit (150) is positioned in the dielectric layer (170) in a thickness direction of the light transmissive substrate (140). Light incident on the dielectric layer (170), for example, is reflected by a side surface of the optical angle change unit (150), and thus an incident angle with respect to a first surface (141) of the light transmissive substrate (140) decreases.

1. A light emitting device, comprising:
an organic functional layer which includes at least a light emitting layer; a light transmissive electrode which faces one surface of the organic functional layer, and transmits light emitted by the light emitting layer; a dielectric layer which faces a surface of the light transmissive electrode opposite to a surface facing the organic functional layer, and transmits the light emitted by the light emitting layer; a light transmissive substrate of which a first surface faces a surface of the dielectric layer opposite to a surface facing the light transmissive electrode, and which transmits the light emitted by the light emitting layer, and emits the light from a second surface opposite to the first surface; and an optical angle change unit of which at least a part is positioned in the dielectric layer, and which decreases an incident angle of light incident on the dielectric layer with respect to the first surface.
