Abstract: A display apparatus can include an adhesive layer disposed on the substrate, a pixel driver chip disposed on the adhesive layer and including a plurality of pads disposed on an upper surface thereof, a planarization surrounding side surfaces of the pixel driver chip, first wires disposed on the planarization layer, and pad contact layers disposed on a plurality of pads of the pixel driver chip. Here, the pad contact layers and the first wires can have the same thickness and can be composed of the same conductive material layer.

Abstract: Discussed are a display device and a method for manufacturing the same, in which a source electrode and a drain electrode are disposed under an active layer of a thin film transistor, thereby simplifying a manufacturing process of the device, reducing a manufacturing time thereof, and reducing a manufacturing cost thereof. To this end, the source electrode, the drain electrode and a light-blocking layer are disposed on a substrate, and constitute the same layer and are made of the same material. An interlayer insulating layer is disposed thereon. A first contact-hole and a second contact-hole are disposed in the interlayer insulating layer. A first connection line connects the source electrode and an active layer to each other, and a second connection line connects the drain electrode and the active layer to each other, whereby the array substrate of the display device can be manufactured using the total of 7 mask processes.
