Abstract

PURPOSE: To provide an display apparatus for electrochemical luminance, light and long in life through an electrochemical radiation employing 10-(p-(substitution) N-phenyl)-9(substitution)-anthracene for organic luminous substance.
CONSTITUTION: This indication device is composed of a transparent substrate 1 including glass substrate, a substrate 2 made of glass, ceramics, or the like, a luminous electrode 3 made of metal, metal oxides, or the like, an anti-electrode 4, a spacer 5 and a luminous liquid 6. For the luminous liquid, applicable is a solution in which a compound as shown by the formula, for example, 10-(p-dimethyl-N- phenyl)-9-phenyl-antracene is dissolved into DMF at a concentration of 10-3 mol/1 and subsequently, tetrabutyl ammonium perchlorate done as a supporting electrolite. Square wave of 50Hz is applied between the electrodes 3 and 4 at a voltage of Vp-p. As a result, a yellow-green light is emitted showing a stability exceeding 100 hours. In the formula, R1 and R2 respectively represent phenyl radical and alkyl group.
