Display device

A display device comprising:

• a first substrate;
• a second substrate facing the first substrate;
• at least two barrier ribs disposed between the first substrate and the second substrate, a space formed between the two barrier ribs defining a cell;
• a first electrode disposed inside the cell;
• a second electrode disposed inside the cell;
• a first emitter layer disposed on the first electrode, the first emitter layer emitting electrons into the cell in response to a voltage applied to the first electrode;
• a second emitter layer disposed on the second electrode, the second emitter layer emitting electrons into the cell in response to a voltage applied to the second electrode, the first emitter layer or the second emitter layer including a nano-porous carbon material;
• a gas filled in the cell to generate ultra-violet rays whenever excited by the electrons emitted from the first emitter layer or the second emitter layer;
• and
• a light emitting layer formed at a location that receives a predetermined amount of transmittance of the ultra-violet rays generated from the gas.
