Classification: CPC G  H | IPC G  H

Claim 21:
22. An electroluminescent display device comprising:
a plurality of pixel arrangements disposed on a substrate and configured to display images,
each pixel arrangement including a plurality of sub-pixels arranged in a 4×4 matrix configuration on the substrate,
the 4×4 matrix configuration including a first row, a second row, a third row and a fourth row extending in a first direction and a first column, a second column, a third column and a fourth column extending in a second direction,
wherein the sub-pixel at the first row and the fourth column, the sub-pixel at the second row and the third column, the sub-pixel at the third row and the second column, and the sub-pixel at the fourth row and the first column have a same predetermined color and extend in a diagonal direction between the first and second directions,
wherein same color sub-pixels of the diagonal direction are arranged to be connected to each other, so that light-emitting layers of the same color sub-pixels of the diagonal direction are connected to each other to thereby form one body,
wherein for each row, the sub-pixels at the first and third columns or at the second and fourth columns have the same predetermined color,
wherein for each column, the sub-pixels at the first and third rows or at the second and fourth rows have the same predetermined color,
wherein a light-emitting diode is disposed in each sub-pixel and includes a first electrode, the light-emitting layer and a second electrode, and
wherein each pixel arrangement further includes:
a first bank extending in strips along the first direction, and covering edges of the first electrodes, and
a second bank disposed on the substrate and separating the sub-pixels from each other in each row.
