Dependent claims

An organic electroluminescent panel, comprising:

an element substrate in which an organic electroluminescent element and a terminal region are formed;
a sealing member that covers the organic electroluminescent element;
a sealing substrate attached to the element substrate with the sealing member interposed therebetween;
and
a first spacer disposed only in a region between the organic electroluminescent element and the terminal region, wherein
the first spacer is disposed away from the sealing member, and wherein
no spacer is arranged on at least one side of outline of a region where the organic electroluminescent element is provided.

4 more elements

A production method of an organic electroluminescent panel by using an element mother substrate provided with a plurality of panel regions in each of which an organic electroluminescent element and a terminal region are formed, the method comprising the steps of:

disposing a sheet sealing member so as not to cover the terminal region and so as to cover the organic electroluminescent element;
disposing a spacer at least in a region between the organic electroluminescent element and the terminal region;
attaching the element mother substrate and a sealing mother substrate;
and
dividing the element mother substrate and the sealing mother substrate together with the sheet sealing member at a same cutting position, wherein
in the spacer-disposing step, the spacer is disposed away from the sheet sealing member, and wherein
no spacer is arranged on at least one side of outline of a region where the organic electroluminescent element is provided.
