Abstract

An organic light-emitting display device includes a thin film encapsulation layer, a transmission pattern, and a color-adjusting pattern. The thin film encapsulation layer covers an organic light-emitting diode. The transmission pattern is in a light-emitting area on the thin film encapsulation layer. The color-adjusting pattern includes ceramic particles as a coloring agent and is in a non-light-emitting area surrounding the light-emitting area on the thin film encapsulation layer.

Claims (23)

1. An organic light-emitting display device, comprising:

an array of organic light-emitting diodes;

transmission patterns spaced apart from each other and disposed in a light-emitting area overlapping the organic light-emitting diodes in a plan view to emit a light generated by the organic light-emitting diodes; and

a color-adjusting pattern including ceramic particles as a coloring agent having a matrix shape surrounding the transmission patterns in a plan view so that an external light reflected by the color-adjusting pattern has a color depending on the ceramic particles,

wherein the transmission patterns have a same reflectivity as the color-adjusting pattern.

2. The organic light-emitting display device as claimed in claim 1 , wherein the transmission patterns include a polymeric resin.

3. The organic light-emitting display device as claimed in claim 1 , wherein the ceramic particles include at least one of Pb 2 Sb 2 O 7 , Co 2 SiO 4 , CoAl 2 O 4 , (Co, Ni, Fe, Cr,

Mn) 3 O 4 , (Sn, Cr)O 2 , (Cr, Al) 2 O 3 , Ca 3 Cr 2 Si 3 O 12 , Ca(Sn, Cr)SiO 5 , Cd(S, Se), (Ti, Cr, Sb)O 2 , (Ti, Cr, W)O 2 , (Zr, Pr)SiO 4 , (Zr, V)(Si, V)O 4 , F 2 O 3 —Zr SiO 4 , (Zr, V)O 2 , (Ce, Pr)O 2 and Y(Al, Cr)O 2 .

4. The organic light-emitting display device as claimed in claim 1 , wherein the organic light-emitting display device is inserted into an external member and the color-adjusting pattern has a same color as an exposed surface of the external member.

5. The organic light-emitting display device as claimed in claim 1 , wherein the transmission patterns include a color filter.

6. The organic light-emitting display device as claimed in claim 5 , wherein:

the transmission patterns include a first color filter in a first light-emitting area, and a second color filter in a second light-emitting area, and

the first color filter and second color filter have different colors from each other.

7. The organic light-emitting display device as claimed in claim 1 , wherein the transmission patterns further include a dye or a carbon black to reduce reflectivity thereof.

8. The organic light-emitting display device as claimed in claim 1 , wherein the color-adjusting pattern has a tapered shape and the transmission patterns have an inversely-tapered pattern to be aligned with the color-adjusting pattern.

9. The organic light-emitting display device as claimed in claim 1 , wherein an area of the color-adjusting pattern is larger than an area of the transmission patterns, in a plan view.

10. The organic light-emitting display device as claimed in claim 1 , wherein the transmission patterns and the color-adjusting pattern are disposed on a same surface so that the transmission patters are adjacent to the color-adjusting pattern in a horizontal direction.

11. An organic light-emitting display device, comprising:

an array of organic light-emitting diodes;

transmission patterns spaced apart from each other and disposed in a light-emitting area overlapping the organic light-emitting diodes in a plan view to emit a light generated by the organic light-emitting diodes; and

a color-adjusting pattern including ceramic particles as a coloring agent having a matrix shape surrounding the transmission patterns in a plan view so that an external light reflected by the color-adjusting pattern has a color depending on the ceramic particles, wherein

the transmission patterns include a color filter, and

the color filter has a same color as light generated by the organic light-emitting diodes.
