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.
