[0174] [Configuration of Organic EL Elements Constituting Example 1]

[0175] figure 2 is a schematic cross-sectional view of an organic EL element constituting Example 1.

[0176] The organic EL element of this example is a so-called bottom emission type, that is, has a transparent substrate, and takes out light from the transparent substrate side. Specifically, as figure 2 As shown, the transparent electrode (1), the light-emitting functional layer (3) and the counter electrode (4) are sequentially stacked on the transparent substrate (2).

[0177] In this organic EL element (100), the transparent electrode (1) of the present invention described above is used as a transparent electrode. Therefore, the organic EL element (100) has a structure capable of extracting generated light (hereinafter, referred to as emitted light (h)) at least from the transparent substrate (2) side.

[0178] In addition, the layer structure of the organic EL element (100) is not limited to the...

Abstract

The present invention addresses the problem of providing: a transparent electrode which has both sufficient electrical conductivity and light transmissivity at the same time, while exhibiting excellent long-term stability; and an electronic device which is provided with this transparent electrode. A transparent electrode (1) according to the present invention comprises, in the following order, a metal affinity layer (11) that contains a compound having a structure represented by general formula (1), a first conductive layer (12a) that is arranged adjacent to the metal affinity layer (11) and contains silver and a metal which is different from silver, and a second conductive layer (12b) that is mainly composed of silver. (In the formula, each of X1 and X2 independently represents a nitrogenatom or CR1; R1 represents a hydrogen atom or a substituent; and A1 represents a residue that constitutes a five-membered or six-membered heteroaryl ring.)

Description

technical field [0001] The invention relates to a transparent electrode and an electronic device. More specifically, the present invention relates to a transparent electrode having both electrical conductivity and light transmission and excellent durability, and an electronic device having the transparent electrode. Background technique [0002] The organic EL element of electroluminescence (hereinafter referred to as "EL") using organic materials is a thin solid-state element, which can emit light at a low voltage of several volts to tens of volts, and has high brightness, high light efficiency, thinness, and lightness. and many other advantages. Therefore, in recent years, backlights for various displays, display panels such as billboards and emergency lights, and surface light emitters such as lighting sources have attracted attention. [0003] The organic EL element as described above is configured such that a light-emitting layer made of an organic material is inserte...
