An organic electroluminescent display panel, which comprises a substrate,
at least one display structure area, at least one first dummy area, and
at least one second dummy area. The display structure area comprises at
least one encapsulation area, at least one pixel area, a first conducting
area, a second conducting area, a wiring area, a first connecting area,
and a second connecting area. The wiring area and the first dummy area
connect the first connecting area, and the two conducting areas and the
second dummy area connect the second connecting area. Besides, the first
and the second connecting areas overlap a selected part of the
encapsulation area of a neighboring display structure area. Accordingly,
the number and capacity of display structure areas on the organic
electroluminescent display panel are increased to obtain a uniform
brightness during a lighting test.
