Patent ID: 7576483

Claim:
A display device comprising: a driving panel having an organic light emitting device which includes (a) a first electrode provided above a substrate, (b) a light emitting layer provided above the first electrode including a blue light emitting layer provided above the first electrode, a middle electrode provided above the blue light emitting layer, a red light emitting layer provided above the middle electrode, and a second electrode provided above the red light emitting layer; (c) an adhesive layer provided above the light emitting layer; (d) a sealing substrate provided above the adhesive layer; (e) a color filter structure between the sealing substrate and the light emitting layer, the color filter structure having three filter layers respectively corresponding to the colors of blue, red, and green; and (f) a single fluorescence conversion layer provided between the light emitting layer and the green filter layer of the color filter structure, the fluorescence conversion layer absorbing blue light but transmitting green light, wherein, the organic light emitting device emits a blue and red light at a wavelength between and including 420 nm to 680 nm.
