Abstract: Provided is an apparatus for electro-forming. The apparatus for electro-forming includes a plating bath which is a space where a substrate is plated and a clamp disposed within the plating bath and configured to grasp the substrate disposed in a horizontal direction. The apparatus for electro-forming further includes an assembly including an anode spaced above the substrate and connected to an external power supply and a plating solution supply unit spaced above the substrate and configured to supply a plating solution. The apparatus for electro-forming also includes a driving unit configured to reciprocate the assembly in a horizontal direction at a distance from the substrate. The assembly further includes an insulator between the anode and the plating solution supply unit.

Abstract: An organic light emitting diode display is disclosed in which a flow control pattern of an organic protective layer is disposed to implement a thin bezel. In an active area and a bezel area defined on a substrate, the flow control pattern disposed reduces the flow of a protective layer so as to minimize area size of the bezel area.

Abstract: Provided is an organic light emitting display device including a plurality of sub pixels. Areas of emission regions of green sub pixels of the plurality of sub pixels are the same as or larger than an area of an emission region of at least one non-green sub pixel of the plurality of sub pixels. Also the organic light emitting display device includes an area of an emission region of a green sub pixel having a low luminance lifetime being the same as or larger than areas of emission regions of non-green sub pixels. Accordingly, it is possible to make the luminance lifetime of the green sub pixel and the luminance lifetimes of the non-green sub pixels uniform. Further, it is possible to minimize a color change of the organic light emitting display device.
