摘要

A display apparatus includes a first semiconductor layer disposed on a substrate; a first gate layer disposed on the first semiconductor layer, the first gate layer including a driving gate electrode; a second gate layer disposed on the first gate layer, the second gate layer including a capacitor upper electrode; a first connecting electrode layer disposed on the second gate layer, the first connecting electrode layer including a transfer wiring; a second connecting electrode layer disposed on the first connecting electrode layer, the second connecting electrode layer including a horizontal connection wiring extending in a first direction; and a third connecting electrode layer disposed on the second connecting electrode layer, the third connecting electrode layer including a vertical connection wiring extending in a second direction that intersects the first direction.

Therefore, a structural difference between the pixels through which the first to third horizontal connection lines DH1 to DH3 pass and the pixels through which the first to third horizontal connection lines DH1 to DH3 do not pass may be reduced. In consequence, a variation in luminance realized by the pixels in case that the same electrical signal is applied to the pixels may be reduced, and the display apparatus capable of displaying high quality images may be implemented. The first to third auxiliary horizontal connection line ADH1 to ADH3 and the first to third horizontal connection lines DH1 to DH3 may be disposed on the same layer.

Similarly, the display apparatus may include a first auxiliary vertical connection line ADV1′ that is spaced apart from the first vertical connection line DV1′ to be electrically insulated from the first vertical connection line DV1′ and the first horizontal connection line DH1, and that has the same extending axis as that of the first vertical connection line DV1′ to be at a side (in a +y direction) of the first vertical connection line DV1′. Likewise, the display apparatus may include a second auxiliary vertical connection line ADV2′ at a side (in the +y direction) of the second vertical connection line DV2′, and a third auxiliary vertical connection line ADV3′ at a side (in the +y direction) of the third vertical connection line DV3′. The first to third auxiliary vertical connection lines ADV1′ to ADV3′ and the first to third vertical connection lines DV1′ to DV3′ may be disposed on the same layer.
