Classification: CPC H | IPC H

Claim 4:
5. A light emitting display device comprising:
a substrate;
a transistor on the substrate, the transistor including a semiconductor layer;
a light shield layer including a lower light shield layer below the semiconductor layer, a side light shield layer on at least one side surface of the semiconductor layer, and an upper light shield layer on the semiconductor layer;
an insulator layer covering the upper light shield layer;
a lower electrode on the insulator layer;
a bank layer on the insulator layer and covering a portion of the lower electrode;
a dummy lower electrode spaced apart from the lower electrode at a same layer level as the lower electrode,
an emissive layer on the lower electrode; and
an upper electrode on the emissive layer,
wherein the dummy lower electrode is connected to the upper light shield layer,
wherein the side light shield layer and the upper light shield layer are in physical contact with each other,
wherein the upper light shield layer entirely covers the semiconductor layer,
wherein the upper light shield layer is electrically connected to the upper electrode via the dummy lower electrode,
wherein the insulator layer includes a contact hole through which the upper light shield layer below the insulator layer is exposed,
wherein the bank layer includes a one-side bank layer and another-side bank layer that are separated from each other to expose a surrounding portion of the contact hole,
wherein a partition is between the one-side bank layer and the other-side bank layer, and
wherein the upper electrode and the dummy lower electrode are electrically connected to each other in an internal space of the one-side bank layer and the other-side bank layer.
