Patent ID: 7981526

Claim:
A display device comprising: a first substrate; a first electrode and a second electrode, which are disposed above the first substrate and insulated from each other, enabling a difference in electrical potential to be given between the first electrode and the second electrode; a second substrate disposed to face the first substrate and spaced apart from the first substrate; a light-emitting layer disposed between the first substrate and the second substrate, the light-emitting layer comprising a light-emitting material which emits light through an electrochemical oxidation or reduction thereof and chloride ions; and a barrier electrode interposed between the first electrode and the second electrode to partition the light-emitting layer, the barrier electrode having a first end and a second end, the first end being in contact with the first substrate and the second end being in contact with the second substrate, and functioning as a spacer, the barrier electrode also functioning as a standard for the electrical potential.
