Abstract: A light emitting display device includes a common power line and a driving power line disposed parallel each other on a substrate; a first pixel disposed between the common power line and the driving power line, and including a left side, a right side, an upper side and a lower side; a first connection part disposed at a first crossing area where the left side and the upper side intersect; a first dummy area disposed at a second crossing area where the right side and the lower side intersect; and a common electrode over the entire substrate as being one layer. The common power line connects to the common electrode at the first connection part. The driving power line passes the first dummy area.

Abstract: Provided is a display device. The display device includes a substrate including a plurality of subpixels. The device includes a driving transistor in each of the plurality of subpixels. The device includes a passivation layer on the driving transistor. The device includes a planarization layer on the passivation layer. The device includes a contact hole in the passivation layer and the planarization layer to expose a source electrode of the driving transistor. The device includes a first anode on a top surface of the planarization layer and the contact hole. The device includes a first bank covering an edge of the first anode. The device includes a second bank on the first anode in the contact hole, in which a height of the second bank is equal to or smaller than a height of the planarization layer. Therefore, the degree of design freedom and the aperture ratio may be improved.
