Claim 10:
11. An electroluminescent display device, comprising:
a substrate;
a first pixel row on the substrate including a plurality of first pixels arranged along a first direction;
a second pixel row on the substrate including a plurality of second pixels arranged along the first direction, the second pixel row being spaced apart from the first pixel row in a second direction;
a third pixel row on the substrate including a plurality of third pixels arrange along the first direction, the third pixel row positioned between the first and second pixel rows;
a first groove between the first and third pixel rows;
a second groove between the second and third pixel rows;
a light emitting diode in each of the first pixels, the second pixels and the third pixels;
a thin film transistor on the substrate and in each of the plurality of first pixels, the plurality of second pixels and the plurality of third pixels;
an insulating layer on the thin film transistor; and
a bank layer on the insulating layer and surrounding each of the plurality of first pixels, the plurality of second pixels and the plurality of third pixels,
wherein the first groove is greater than the second groove,
wherein the light emitting diode includes a first electrode, an emitting layer on the first electrode and a second electrode covering the emitting layer,
wherein the first and second grooves are formed in the bank layer,
wherein the bank layer includes a first bank layer positioned between the plurality of first pixels having a first thickness and a second bank layer positioned between the first pixel row and the third pixel row and having a second thickness, and
wherein the second thickness is greater than the first thickness.
