Flat panel display device with anti-reflection layer having concentration gradient and fabrication method thereof

A flat panel display device comprising:

• an insulation substrate;
• a plurality of signal lines arranged on the insulation substrate;
• a plurality of pixel regions defined by the plurality of signal lines;
• a plurality of light emitting regions which include corresponding electroluminescent layers, and are formed on the respective pixel regions;
• a plurality of thin film transistors which are connected to the corresponding signal lines so as to be arranged on each of the pixel regions respectively;
• and
• a plurality of anti-reflection layers which are formed under the respective light emitting regions, wherein each of the anti-reflection layers is electrically separated between neighboring pixel regions, and connected to a corresponding one of the thin film transistors.

A method of fabricating a flat panel display, the method comprising:

• forming a thin film transistor having source/drain electrodes on an insulation substrate of the display;
• forming an insulation layer on the insulation substrate having the thin film transistor;
• forming a via hole which exposes one of the source/drain electrodes by etching a corresponding area of the insulation layer;
• and
• forming an anti-reflection layer connected to the one of the source/drain electrodes exposed through the via hole.

A flat panel display device, comprising:

• a first electrode layer;
• a second electrode layer;
• and
• an organic electroluminescent layer,
• wherein one of the first electrode layer and the second electrode layer functions as an anti-reflection layer, which prevents light of the organic electroluminescent layer from penetrating the anti-reflection layer.
