Abstract

A functional panel is provided. The functional panel includes a first substrate, a second substrate, a bonding layer, a functional element, a protective layer, and a terminal. The bonding layer is positioned between the first and second substrates. The functional element is surrounded by the first substrate, the second substrate, and the bonding layer. The terminal is electrically connected to the functional element and provided not to overlap with one of the first and second substrates. The protective layer is provided to be in contact with side surfaces of the first and second substrates and an exposed surface of the bonding layer. A surface of the terminal is partly exposed without being covered with the protective layer. The surface of the terminal partly includes a material having a lower ionization tendency than hydrogen.

First claim

What is claimed is:

1 . A functional panel comprising:
a first substrate; a second substrate; a bonding layer; a functional element; a protective layer; and a terminal, wherein the bonding layer is positioned between the first substrate and the second substrate, wherein the functional element is surrounded by the first substrate, the second substrate, and the bonding layer, wherein the terminal is electrically connected to the functional element, wherein the terminal is provided not to overlap with one of the first substrate and the second substrate, wherein the protective layer is provided to be in contact with a side surface of the first substrate, a side surface of the second substrate and an exposed surface of the bonding layer, and wherein a part of a surface of the terminal is exposed without being covered with the protective layer.

2 . The functional panel according to claim 1 , wherein the part of the surface of the terminal includes a material having a lower ionization tendency than hydrogen.

3 . The functional panel according to claim 2 , wherein the material is palladium, iridium, gold, or platinum.

4 . The functional panel according to claim 1 , wherein the protective layer includes at least one of aluminum oxide, hafnium oxide, zirconium oxide, titanium oxide, zinc oxide, indium oxide, tin oxide, indium tin oxide, tantalum oxide, silicon oxide, manganese oxide, nickel oxide, erbium oxide, cobalt oxide, tellurium oxide, barium titanate, titanium nitride, tantalum nitride, aluminum nitride, tungsten nitride, cobalt nitride, manganese nitride, and hafnium nitride.

5 . The functional panel according to claim 1 ,
wherein the terminal has a stacked structure of a first layer and a second layer over the first layer, wherein a part of a surface of the second layer is exposed, wherein the second layer includes a material having a lower ionization tendency than a material included in the first layer.

6 . The functional panel according to claim 5 , wherein the second layer includes palladium, iridium, gold, or platinum.

7 . The functional panel according to claim 1 , wherein the first substrate and the second substrate have flexibility.

8 . The functional panel according to claim 1 , further comprising an FPC,
wherein the FPC is electrically connected to the terminal.

9 . A light-emitting panel, comprising the functional panel according to claim 1 ,
wherein the functional element includes a light-emitting element.

10 . A display panel, comprising the functional panel according to claim 1 ,
wherein the functional element includes a display element.

11 . A display panel, comprising the functional panel according to claim 1 ,
wherein the functional element includes a display element and a transistor.

12 . A sensor panel, comprising the functional panel according to claim 1 ,
wherein the functional element includes a sensor element.
