Abstract:
1. An organic electroluminescent(EL) display, comprising: a first substrate having a thin film transistor; a second substrate having a light emitting region and a non-light emitting region; an assistant electrode formed on the non-light emitting region of the second substrate; a first electrode formed on the second substrate; a plurality of partition walls formed on the first electrode in the non-light emitting region; an insulation layer to cover a portion of each partition wall; a light emitting layer formed on the first electrode of the light emitting region; and a second electrode formed on the light emitting layer, wherein the second electrode formed over the insulation layer is electrically and directly connected to the thin film transistor of the first substrate; wherein the insulation layer is formed between the first electrode and the light emitting layer and between the partition walls and the light emitting layer so that the insulation layer is formed on a portion of an upper surface of each partition wall that faces the first substrate and on a portion of a side surface of each partition wall, and wherein the plurality of partition walls comprises a first section having a lower surface thereof wider than an upper surface thereof to be formed with the second electrode, and a second section being formed on the upper surface of the first section, and wider than the lower surface of the first section.
