Abstract

An electroluminescence light emitting display system having: an electroluminescence light emitting sheet which comprises a light-emitting layer containing electroluminescence light-emitting elements therein, and an electrode section comprising a plurality of electrode pairs which are disposed with a predetermined arrangement, wherein each of the electrode pairs includes first and second electrodes which are electrically separated from each other with a spacing region and disposed in one surface side of the light-emitting layer with a predetermined arrangement; and a voltage application unit for applying a predetermined voltage between the first and second electrodes. Each width of the first and second electrodes is 0.2-0.5 mm and a width of the spacing region between the first and second electrodes is 0.2-0.3 mm. When an electrically conductive material is placed on the other surface side of the light-emitting layer and a voltage application between the first and second electrodes is performed by the voltage application unit, a portion of the light-emitting layer corresponding to the placed electrically conductive material emits light.
