Embodiment Construction

[0233] According to the above-described manufacturing method, light emitting devices 1010R, 1010G, and 1010B are formed, which include an organic layer 1011 emitting blue light (Embodiment 1) or ultraviolet light (Embodiment 2) as an excitation light source, and forming a wavelength conversion portion. The wavelength conversion portion is formed by sequentially stacking the wavelength conversion layer 1012 and the wavelength selection film 1013A from the side closer to the upper electrode 1017 between the upper electrode 1017 and the protective layer 1018. In addition, as a comparative example, a display unit including red, green, and blue light emitting devices, each light emitting device including only the wavelength conversion layer 1012 formed on the upper electrode 1017, was formed. In addition, a display unit is formed in which the wavelength selection film 1013B is formed under the wavelength conversion layer 1012 of the wavelength conversion portion, as Examples 3 and 4,...

Abstract

A display unit includes: a plurality of light-emitting devices; and a separation section disposed between any adjacent two of the plurality of light-emitting devices and including a photoexcited material. A light-emitting device includes: an excitation light source; a wavelength conversion layer converting excitation light emitted from the excitation light source into light of a wavelength different from a wavelength of the excitation light; and a wavelength selection film disposed on a surface farther from the excitation light source of the wavelength conversion layer.

Description

Background technique [0001] The present disclosure relates to a display unit including, for example, a self-luminous device such as an organic EL (Electro Luminescence) device and a manufacturing method thereof, and the present disclosure relates to an electronic device and a lighting unit. In addition, the present disclosure relates to a light emitting device using wavelength-converted excitation light and a method of manufacturing the same. [0002] As the development of the information and communication industry accelerates, high-performance display devices are required. For example, an organic EL (Electro Luminescence) device is a self-luminous display device, and has excellent viewing angle width, contrast and response speed (for example, see Japanese Unexamined Patent Application Publication No. 2008-53229). Such self-luminous type devices are individually separated by a separation film made of an insulating material. [0003] In recent years, displays using organic EL...
