Display, method for producing display, and electronic apparatus

1. A display comprising:

a first substrate including elements arranged on a main surface of the first substrate;

a second substrate arranged so as to face the main surface of the first substrate on which the elements are arranged;

a first sealing layer arranged on the first substrate and the elements and between the first substrate and the second substrate, the first sealing layer sealing the elements; and

a second sealing layer arranged between the first substrate and the second substrate so as to abut and surround the first sealing layer,

wherein,

the second substrate has a peripheral projection, the entirety of which projects toward the main surface of the first substrate to form a first portion of a planar sidewall, the peripheral projection overlapping and surrounding the first sealing layer but spaced from the first sealing layer so as to have a first space therebetween,

the peripheral projection is spaced from the first substrate so as to have a second space therebetween but with no portion of the first sealing layer therebetween,

the second sealing layer is arranged between the first substrate and the second substrate so as to fill the first and second spaces, the second sealing layer being in contact with both the peripheral extension and the first substrate, and

the second substrate is optically transparent and comprises plastic, glass or a foil with an insulating film.

2. The display according to claim 1 , wherein the second sealing layer is arranged only between the first substrate and the second substrate.

3. The display according to claim 1 , wherein:

each of the first substrate and the second substrate is composed of an organic material, and

a protective film is arranged on at least one surface of each of the first substrate and the second substrate.

4. The display according to claim 1 , wherein the peripheral projection has a height smaller than a thickness of the first sealing layer.

5. The display according to claim 1 , wherein the second substrate and the peripheral projection are a unitary structure.

6. The display according to claim 1 ,wherein the elements are organic electroluminescent elements.

7. A method for producing a display comprising:

a first step of providing a first substrate with a first sealing layer thereon;

a second step of feeding an uncured material for a second sealing layer onto the first substrate to so as to be in contact with the first substrate and adjacent to and to surround the first sealing layer;

a third step of arranging a second substrate with a peripheral projection so as to face the first substrate such that the entirety of peripheral projection projects toward the first substrate and the first sealing layer is surrounded by the peripheral projection, and so that the first sealing layer is arranged between the first substrate and the second substrate and the peripheral projection is spaced apart from the first sealing layer and the first substrate;

a fourth step of allowing the material for the second sealing layer that has been fed around the first sealing layer to entirely fill by capillary action a first space between the peripheral projection and the first substrate and a second space between first sealing layer and the peripheral projection, the first space having no portion of the first sealing layer therein and the second sealing layer being in contact with both the peripheral extension and the first substrate; and

a fifth step of curing the material for the second sealing layer between the first substrate and the second substrate to form the second sealing layer,

wherein, as a result of the foregoing steps,

(a) the second sealing layer is arranged between the first substrate and the second substrate so as to fill the first and second spaces,

(b) the first sealing layer and the second sealing layer are arranged adjacent to each other along the first substrate, and

(c) the second substrate is optically transparent and comprises plastic, glass or a foil with an insulating film.

8. The method according to claim 7 ,wherein:

the third step is performed in a vacuum atmosphere; and

after the third step is performed, the fourth step is performed by increasing the pressure to atmospheric pressure.

a first sealing layer arranged on the first substrate and the elements and between the first substrate and the second substrate, the first sealing layer sealing the elements; and

a second sealing layer arranged between the first substrate and the second substrate so as to abut and surround the first sealing layer,

wherein,

the second substrate has a peripheral projection, the entirety of which projects toward the first substrate on which the elements are arranged to form a first portion of a planar sidewall, the peripheral projection overlapping and surrounding the first sealing layer but spaced apart from the first sealing layer so as to provide a first space therebetween,

the peripheral projection is spaced from the first substrate so as to have a second space therebetween but with no portion of the first sealing layer therebetween,

the second sealing layer is arranged between the first substrate and the second substrate so as to fill the first and second spaces, the second sealing layer being in contact with both the peripheral extension and the first substrate,

the first sealing layer and the second sealing layer are arranged adjacent to each other along the first substrate, and

the second substrate is optically transparent and comprises plastic, glass or a foil with an insulating film.

10. The electronic apparatus according to claim 9 , wherein the panel is a display panel.
