  • Patent number: 9466647
    Abstract: A flat panel display device includes: a substrate; an insulating layer having first, second, and third openings; a plurality of first lines on the insulating layer overlapped with the first openings, extending in a first direction, and including a first organic light-emitting layer; a plurality of second lines on the insulating layer overlapped with the second openings, extending in the first direction, and including a second organic light-emitting layer that is different from the first organic light-emitting layer; and a plurality of third lines on the insulating layer overlapped with the third openings, extending in the first direction, and including a third organic light-emitting layer that is different from the first and second organic light-emitting layers. Adjacent first and second lines are partially overlapped with each other, and the first, second, and third lines are not overlapped with the openings overlapped with other ones of the lines.

  • Publication number: 20140291618
    Abstract: A method of manufacturing an organic light-emitting display device, wherein a voltage drop of a counter electrode is effectively reduced, includes: (i) forming a layer on a substrate using a first deposition assembly, wherein the first deposition assembly includes a patterning slit sheet that includes patterning slits corresponding to sub-pixels emitting light in a first wavelength band from among n sub-pixels of each of pixels and does not include a patterning slit in regions corresponding to spaces between pixels in a second direction crossing a first direction and parallel to the substrate fixed to a transfer unit; and (ii) forming a layer on the substrate using a second deposition assembly, wherein the second deposition assembly includes a patterning slit sheet that includes patterning slits corresponding to the pixels and does not include a patterning slit in regions corresponding to spaces between the pixels in the second direction.
