Abstract: An organic light emitting display device has a display panel including a first subpixel, a second subpixel, a data line, and sensing lines. The sensing lines may include a vertical sensing line and a horizontal sensing line connected to the vertical sensing line. The horizontal sensing line may be formed of a source/drain metal layer present on the first substrate, and one portion thereof connected to a first electrode of a sensing transistor of the first subpixel and the other portion thereof connected to a first electrode of a sensing transistor of the second subpixel may be positioned in a region intersecting with the data line, and electrically connected by a connection electrode formed of an insulated light blocking layer below the source/drain metal layer present on the first substrate.

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.
