Abstract (en)
[origin: EP1122984A2] A long-life type colorful electroluminescent (EL) display panel is disclosed. The EL display panel comprises a luminescent laminate, two electrodes located at the two sides of the luminescent laminate, several terminals, and a display surface. One of the two electrodes includes plural separated sub-electrodes. Each sub-electrode comprises at least one branch portion and a bus bar connecting at least one branch portion to one of the terminals. Each of the branch portions in one sub-electrode is accompanied with one branch portion in a sub-electrode different from the one sub-electrode, and extends in parallel thereto in a position corresponding to a portion of the display surface which is representative of substantially the same area. By means of the above structure, the display panel will have a life span more than double the normal and can display colorfully. <IMAGE>
