DISPLAY DEVICE USING QUANTUM DOT
First Claim
1. A display device comprising:
- a backlight unit, emitting a UV light;
a first substrate and a second substrate on the backlight unit;
a plurality of partition walls between the first and second substrates, defining a plurality of sub-pixels;
a plurality of Quantum Dot (QD) units disposed within the plurality of sub-pixels, and emitting a visible light while absorbing the UV light; and
a first driving electrode and a second driving electrode disposed between the first substrate and the second substrate for controlling the QD units to selectively absorb the UV light according to the voltages applied to the first driving electrode and the second driving electrode.

Abstract
A display device using quantum dots includes a first substrate and a second substrate disposed to face each other, a partition wall formed between the first and second substrates and defining a unit pixel, a first electrode formed on the first substrate, a second electrode formed to correspond to the first electrode, a backlight unit formed under the first substrate and having a UV light source, a UV blocking film formed above the second substrate, and a red light emitting layer where red quantum dots are formed, a blue light emitting layer where blue quantum dots are formed, and a green light emitting layer where green quantum dots are formed, which are disposed in the unit pixel.
