1. An organic light emitting display device, comprising:

  • a first substrate comprising a single layer or multiple layers;

    a second substrate comprising a single layer or multiple layers, the second substrate comprising an inner surface facing the first substrate;

    an array of organic light emitting pixels formed on the first substrate and interposed between the first and second substrates, the array comprising a top surface opposing the inner surface of the second substrate, wherein the top surface and the inner surface has a gap therebetween, and the gap has a gap distance measured between the top surface and the inner surface wherein the gap distance is equal to or greater than 10 μ

    m, said array comprising elongate strips of anode and elongate strips of cathode where the elongate strips of anode are arranged generally perpendicular to the elongate strips of cathode, and wherein each pixel is defined by the intersections of the elongate strips of anode and the elongate strips of cathode and an organic layer interposed therebetween; and

    a frit seal interconnecting the first and second substrates while surrounding the array, wherein the frit seal, the first substrate and the second substrate in combination define an enclosed space in which the array is located, wherein the frit seal has a height between the first and second substrates from about 2 to about 300 μ

    m and the frit seal is prepared from a frit paste comprising about 10-30 wt % organic materials and about 70-90 wt % inorganic materials where the organic materials comprise 0-30 wt % binder(s) and about 70-100 wt % solvent(s), and wherein the enclosed space does not include a desiccant.
