Abstract

The present invention provides an EL element comprising at least a first electrode, an EL layer formed on the first electrode, and a second electrode formed on the EL layer and a method for producing the same. In the element, at least one layer of a wettability-changing component layer is formed by light irradiation.

Description

[0001] This application is a divisional application of the Chinese application whose application number is CN01117383.1 (the application date is February 23, 2001), and the invention name is "Electroluminescent Element and Its Manufacturing Method". technical field [0002] The present invention relates to an electroluminescence element (also referred to as an EL element in this specification), particularly an organic thin-film EL element usable in a display device, and a method for manufacturing the same. Background technique [0003] The application of EL elements as self-luminous planar display elements has attracted widespread attention. Among them, organic thin-film EL displays that use organic substances as light-emitting materials can achieve high-intensity light emission even when a voltage below 10V is applied, and the luminous efficiency is very high. It can also emit light with a simple device structure, and it is expected to be applied to high-precision full-color...
