Abstract: A display apparatus includes a display area and a peripheral area, a light-emitting diode including a sub-pixel electrode, a first data line in the display area and extending in a first direction, an input line in the peripheral area, and a connection wire in the display area and transmitting a data signal input to the first data line. The connection wire includes a first connection line extending in the first direction and a second connection line extending in a second direction, the first connection line overlaps the sub-pixel electrode with an insulating layer interposed between the sub-pixel electrode and the first connection line, the insulating layer includes a first insulating layer and a second insulating layer disposed on the first insulating layer, dielectric constants of the first and second insulating layers are different, and one of the first insulating layer and the second insulating layer includes BCB.

Abstract: A display apparatus includes a substrate including a display area including a first pixel area and a second pixel area which are adjacent to each other along a first direction, and a peripheral area outside the display area, a organic insulating layer disposed over the substrate, a connection metal layer disposed on the organic insulating layer, and a planarization layer covering the connection metal layer. The planarization layer includes a first inner surface defining a contact hole corresponding to the first pixel area and exposing at least a part of a connection metal layer to outside the planarization layer, the first inner surface being a forward-tapered inclined surface, and a second inner surface defining a 1-1st hole which is between the first pixel area and the second pixel area along the first direction and exposes a part of the organic insulating layer to outside the planarization layer, the second inner surface being a reverse-tapered inclined surface.
