Abstract: Provided are an array substrate and a method for manufacturing the same, a display device and a method for manufacturing the same. In the array substrate, the drain of the thin film transistor is extended to form a drain extension line, wherein the drain extension line is between adjacent sub-pixel units of the pixel region, thus it can block the light at the boundary between the sub-pixel units, thereby avoiding light leakage duo to the disordered electric field at the boundary between the sub-pixel units. The array substrate of the present disclosure is suitable for a multi-domain oriented IPS mode array substrate. The drain extension line can be used as a light blocking strip to prevent light leakage due to the disordered electric field at the boundary between the sub-pixels, and is overlapped with the middle portion of the common electrode line to form a storage capacitor.

Abstract: The disclosure discloses an array substrate, a display panel, and a display device. A first power signal line is configured to be formed by electrically connecting a first signal line located in a first source-drain metal layer and a second signal line located in a second source-drain metal layer through a via hole, which is equivalent to that the first power signal line is composed of the first signal line and the second signal line connected in parallel, and the equivalent resistance of the parallel-connected first signal line and second signal line included in the first power signal line is smaller than the resistance of any of the signal lines. Thus, the resistance of the first power signal line may be effectively reduced, so that an IR drop of a display panel with an array substrate may be reduced, and the display uniformity of the display panel is improved.
