<P>PROBLEM TO BE SOLVED: To provide an electronic light emission system which changes a color of light emitted by a light emitting layer during operation. <P>SOLUTION: An electronic light emission system includes an electronic light emitting device (1) having a two dimensional first electrode (2) made of a transparent material. Layers (3, 4) formed by light emission dielectric bodies are respectively disposed on spreading surfaces of the first electrode (2). The light emitting layers (3, 4) are transparent and are formed by materials emitting light of wavelengths which are different from each other. Electrodes (5, 6) are respectively disposed on spreading surfaces of the light emitting layers (3, 4), which face a common electrode (2) at back surfaces. A support layer (7) formed by a transparent material is disposed on a front side of the light emitting device (1). Voltage sources (11, 12) are connected between the two electrodes (out of 5, 2, 6) that are located continuously. <P>COPYRIGHT: (C)2012,JPO&INPIT |
