- the gas barrier film 20 having the gas barrier layer 22 having such a configuration is excellent in durability in a high temperature and high humidity environment.
- the gas barrier layer 22 is formed of a coating solution in which the silicon-containing layer 23 contains polysilazane, and the region A satisfies the following formula (3).
- the region A is a region where silicon atoms and metal atoms are present at the same time, and the gas barrier film 20 has a high gas barrier property when the ratio of metal atom / silicon atom is 0.2 or more and 3.0 or less. Is expressed.
- the ratio of metal atom / silicon atom is preferably 0.5 or more and 2.0 or less.

- the ratio of nitrogen atom / silicon atom is less than 0.05, the content ratio of polysilazane contained in the silicon-containing layer 23 is low, or the polysilazane is modified to reduce silicon-nitrogen bonds. It is thought to decline. Also, when the ratio of nitrogen atom / silicon atom exceeds 0.6, the amount of silicon atom and metal atom are relatively decreased and the silicon-metal bond is also decreased by the increase of nitrogen atom. It is considered that the gas barrier property is lowered.
- silicon-nitrogen bond (Si-N bond) of polysilazane is in contact with a metal atom formed by a method such as a vapor phase film-forming method, energy such as vacuum ultraviolet light is applied in contact with the metal atom. Therefore, it is considered that the silicon-metal bond is easily changed. For this reason, it is considered that a significantly higher gas barrier property can be obtained than when other silicon-containing compounds having no silicon-nitrogen bond are used.

It can be carried out by a method such as storing the film under conditions of low temperature and humidity, or storing it in a dry nitrogen atmosphere.
- the region A has the region B represented by the following formula (4). Is preferred.
- the above equation (4) means that the total number of bonds of O and N is less than the total number of bonds of Si and M.
- (4 + ax) ⁇ (3y + 2z) in the above formula (4) exceeds 0, it is considered that a direct bond between Si and M is formed. It is considered that as the value of (4 + ax) ⁇ (3y + 2z) increases, the ratio of direct bonding between Si and M increases, the density of the composition in region A increases, and the gas barrier properties are further improved. Therefore, (4 + ax) ⁇ (3y + 2z) in the region B is more preferably 1 or more, further preferably 2 or more, and particularly preferably 3 or more. In addition, when the area
- Control of the value of (4 + ax) ⁇ (3y + 2z) is, for example, in the case where the formation of the layer containing the metal M is performed by sputtering, for example, a metal as a target or a metal in which oxygen is lost stoichiometrically This can be done by using an oxide and appropriately adjusting the amount of oxygen introduced during sputtering.
- the position where the region B is formed is not particularly limited, but is preferably in the vicinity of the interface between the region A and the metal-containing layer 24 or in the vicinity of the interface between the region A and the silicon-containing layer 23. If the region B is formed in the vicinity of these interfaces, it means that a co-oxynitride layer of Si and metal M is formed at the interface between the metal-containing layer 24 and the silicon-containing layer 23. This is because the co-oxynitride layer of Si and M is considered to exhibit high wet heat resistance.
- the composition of the region A and the region B can be measured by the following method.
- XPS composition analysis a composition distribution profile in the thickness direction is measured in the vicinity of the interface between the metal-containing layer 24 and the silicon-containing layer 23, and the composition is indicated by SiM x N y O z At this time, it is determined whether or not the region A is present from the relationship between x and y.

- the silicon-containing layer 23 is not completely stable against oxidation, and may be gradually oxidized in a high-temperature and high-humidity environment, resulting in a decrease in gas barrier properties.
- the gas barrier film 20 has a metal-containing layer 24 together with the silicon-containing layer 23, and has the region A in the vicinity of the interface between the silicon-containing layer 23 and the metal-containing layer 24. Since the metal-containing layer 24 is more easily oxidized than the silicon-containing layer 23, the metal-containing layer 24 is oxidized first and the oxidation of the silicon-containing layer 23 is suppressed. For this reason, it is thought that the gas barrier film 20 is excellent in durability in a high temperature and high humidity environment. That is, it is considered that the gas barrier film 20 has the region A, whereby the durability under a high temperature and high humidity environment is particularly improved.

From this result, even in metals other than Nb, the reliability of the organic EL element can be improved by having the region A in the gas barrier layer.
- the gas barrier film on which the light scattering layer was formed was mounted on the lower electrode side of the chamber of a parallel plate type plasma CVD apparatus (manufactured by Anelva, PED-401).
- the chamber of the plasma CVD apparatus was depressurized to an ultimate vacuum of 1.0 ⁇ 10 ⁇ 2 Pa using an oil rotary pump and a turbo molecular pump.
- nitrogen gas (N 2 ) was introduced from the raw material supply apparatus into the chamber at 30 sccm via the raw material supply nozzle.
- the pressure adjusting valve between the chamber and the vacuum pump was adjusted to adjust the pressure in the chamber to 20 Pa.
- Table 3 shows the metal M contained in the metal-containing layer in the organic EL elements of the samples 201 to 209, the composition of the region A, and the evaluation results.
- samples 201 to 209 in which silicon nitride is formed using a plasma CVD method as the smoothing layer have both improved storage stability and folding storage stability compared to the above samples 101 to 109. ing. From this result, it can be seen that, as an organic EL element, it is preferable to provide a smoothing layer formed by a dry process rather than a smoothing layer formed by a wet process from the viewpoint of improving the storage stability. This is presumably because the layer formed by the dry process has a higher gas blocking effect (barrier property) than the layer formed by the wet process.
