A supporting electrolyte such as butylammonium/gucchlorate is added.

上で発光させるものである。Furthermore, when the electrode potential is negative, anion radicals are generated according to equation 21. The intestinal ion radicals and anion radicals thus generated combine on the electrode surface to generate one molecule R* in an excited state and one molecule R in a ground state. When this excited state R* returns to the ground state, light hv is emitted as shown in the formula t4}. As mentioned above, electrochemiluminescence involves applying a DC or AC voltage between a pair of electrodes to generate light on the electrode surface.
従来、この電気化学発光表示装置の電極構造としては「

た。Conventionally, the electrode structure of this electrochemiluminescent display device was as follows.
Segment electrodes and common electrodes were arranged at appropriate intervals, and only one of the electrodes emitted light for display.
その目的の電極だけを発光させるために「セグメント電

を提供することを目的とする。In order to make only the target electrode emit light, a method was used such as increasing the area ratio of the segment electrode and the common electrode. It is difficult to hold down the display, and the electrodes that are not part of the display end up emitting light, making the display difficult to understand and making it impossible to obtain a clear, easy-to-read display.In order to solve the above-mentioned drawbacks, the present invention makes only the segment electrodes or the common electrode emit light. It is an object of the present invention to provide a clear and easy-to-read self-luminous type display device that causes both electrodes to emit light and performs a predetermined display without using such technically difficult methods.
