Title: LIGHT-EMITTING DEVICE PRODUCTION METHOD AND LIGHT-EMITTING DEVICE
Abstract:
A light-emitting device (10) that has a hole injection layer (121), a hole transport layer (122), and a light-emitting layer (123). The hole transport layer (122) has a first organic layer (122a), a second organic layer (122b), and a third organic layer (122c). The first organic layer (122a) is formed upon the hole insertion layer (121) and includes a first hole transport material. The second organic layer (122b) is formed upon the first organic layer (122a) and includes a second hole transport material. The third organic layer (122c) is formed upon the second organic layer (122b) and includes the second hole transport material. The second organic layer (122b) is formed using an application method, and the third organic layer (122c) is formed using a vapor deposition method.
