Abstract

The invention provides an organic electroluminescence device having an input function, including: an element substrate that has a light-emitting layer sandwiched between a pair of electrodes; a sealing substrate that seals the element substrate; a first detection electrode that is provided at the inner-surface side of the sealing substrate; a second detection electrode that is provided at the outer-surface side of the sealing substrate; the second detection electrode having a detection axis that is not the same as that of the first detection electrode; a dielectric film that is formed on the second detection electrode; and a detection unit that detects a position at which electrostatic capacitance is generated via the dielectric film between the first detection electrode and the second detection electrode.

Claims (14)

1. An organic electroluminescence device having an input function, comprising:

an element substrate that has a light-emitting layer sandwiched between a pair of electrodes;

a sealing substrate that seals the element substrate;

a first detection electrode that is provided at an inner-surface side of the sealing substrate;

a second detection electrode that is provided at an outer-surface side of the sealing substrate, the second detection electrode having a detection axis that is not the same as that of the first detection electrode;

a dielectric film that is formed on the second detection electrode; and

a detecting section that detects a position at which electrostatic capacitance between the first detection electrode and the second detection electrode is generated, the electrostatic capacitance being generated via the dielectric film.

2. The organic electroluminescence device having an input function according to claim 1 , wherein the first detection electrode is configured as a part of a light-shielding film that is formed at the inner-surface side of the sealing substrate.

3. The organic electroluminescence device having an input function according to claim 2 , wherein another part of the light-shielding film that does not constitute the first detection electrode has a fixed potential.

4. The organic electroluminescence device having an input function according to claim 1 , wherein the pair of electrodes is made up of a positive electrode and a negative electrode; and the negative electrode is formed in a planar pattern on the element substrate.

5. An electronic apparatus that is provided with the organic electroluminescence device having an input function according to claim 1 .

6. The organic electroluminescence device having an input function according to claim 1 , wherein the inner-surface side of the sealing substrate faces the element substrate and the outer-surface side of the sealing substrate opposes the inner-surface side,

the first detection electrode is formed on the inner-surface side of the sealing substrate, and

the second detection electrode is formed on the outer-surface side of the sealing substrate.
