Organic light-emitting display device including pixel defining layer with openings and black matrix with openings

An organic light-emitting display device, comprising:

• a plurality of pixels, wherein each of the plurality of pixels comprises a first electrode, a second electrode arranged in common over the plurality of pixels, and an organic emission layer arranged between the first electrode and the second electrode, wherein the first electrode has a circular shape;
• a pixel-defining layer surrounding a portion of the first electrode and comprising a first opening overlapping a first pixel of the plurality of pixels;
• an encapsulation layer arranged on the second electrode;
• a black matrix arranged on the encapsulation layer and comprising a circular second opening overlapping the first opening;
• and
• a first color filter of a plurality of color filters, the first color filter overlapping the circular second opening, wherein the circular second opening is larger than the first electrode.

An organic light-emitting display device, comprising:

• a plurality of pixels, wherein each of the plurality of pixels comprises a first electrode, a second electrode, and an organic emission layer arranged between the first electrode and the second electrode;
• a pixel-defining layer surrounding an outer portion of the first electrode and comprising a plurality of circular first openings, each of the plurality of circular first openings overlapping at least a portion of a respective pixel of the plurality of pixels;
• an encapsulation layer arranged on the second electrode;
• a black matrix arranged on the encapsulation layer and comprising a plurality of circular second openings, each of the plurality of circular second openings overlapping a respective circular first opening of the plurality of circular first openings;
• and
• a plurality of color filters, each of the plurality of color filters overlapping a respective circular second opening of the plurality of circular second openings, wherein each of the plurality of circular second openings is larger than each of the plurality of circular first openings.
