Disclosed is a thin film electroluminescent device of this invention comprising a transparent substrate (11), a transparent electrode (12), a fluorescent layer (14) emitting a light when being charged with a certain voltage, a first and second insulating layer (13,15) being laminated on the top and the bottom of the fluorescent layer (14) to make a dopant be excited and emit a light efficiently, a first light absorbing layer (17) being laminated on the second insulating layer (15) to improve the function of contrast of the device of electroluminescence, a rear electrode (16) formed on the first light absorbing layer (17) at regular intervals, a rear insulating layer (18) being laminated on the rear electrode (16) to prevent the current from leaking from the rear electrode, and a second light absorbing layer (19) being laminated on the rear insulating layer (18) to blacken the etched portion of the first light absorbing layer (17). |
