An organic electroluminescence device includes a first substrate, a first electrode
layer formed over the first substrate, an organic light emitting layer formed over
the first substrate, a second electrode layer formed over the organic light emitting
layer, a second substrate, a seal pattern on an outer portion of the first substrate
or the second substrate for forming a cell gap between the two substrates and for
attaching the two substrates, and a plurality of cell gap maintaining structures
located between the first substrate and the second substrate.
