Structure of thin film electroluminescent device

A thin film electroluminescent device, comprising:

• a) a substrate;
• b) a transparent electrode formed on said substrate;
• c) a first insulating layer formed on said transparent electrode;
• d) a fluorescent layer formed on said first insulating layer and including dopants for emitting light when being charged;
• e) a second insulating layer formed on said fluorescent layer wherein said first and second insulating layers effectively excite the dopants in said fluorescent layer and make said dopants emit light;
• f) a first light absorbing layer formed on said second insulating layer and including an etched portion to improve the effect of contrast by preventing light from being reflected, wherein said first light absorbing layer is produced from SiNx and the value of `x` is less than 1.33;
• g) a rear electrode formed on said first light absorbing layer;
• h) a rear insulating layer formed on said rear electrode to prevent current leakage;
• and
• i) a second light absorbing layer formed on said rear insulating layer for preventing blackening of the etched portion of said first light absorbing layer.
