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.

Abstract: Discussed is a GIP-type display device having a bridge line that connects two neighboring divided capacitors with each other in a capacitor area such that leakage does not occur in the capacitor area in a non-display area when supplying a scan signal or a sensing signal to a thin-film transistor. Further, a method for manufacturing the same is discussed. To this end, a light-blocking film is disposed on a substrate, a buffer and gate insulating film is disposed on the light-blocking film, a gate metal film is disposed on the buffer and gate insulating film, an interlayer insulating film is disposed on the gate metal film, and a source and drain metal film is disposed on the interlayer insulating film, and the source and drain metal film forms the bridge line connecting the two neighboring divided capacitors with each other.

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.
