ABSTRACT:
An organic electroluminescence element having a thin film of organic compound containing at least a light-emitting layer interposed between an anode and a cathode is disclosed. This element is driven by utilizing the sheet resistance of the anode or the cathode in a manner such that the distribution of brightness or color in a single light-emitting plane is modulated with the elapse of time. For example, at least either of the anode and the cathode is furnished with not less than two connecting parts, voltages are applied severally to the connecting parts, and at least one of the factors, i.e. amplitude, frequency, phase, and offset of the voltage applied to each of the connecting parts is modulated. As a result, a completely novel organic electroluminescence element that is capable of causing the brightness and the color to be so modulated as to induce waving in a single light-emitting plane can be realized.
