This disclosure discloses an array substrate comprising: a substrate; a driver chip, located on the substrate; a plurality of data lines, arranged in turn on the substrate, extended longitudinally and electrically connected to the driver chip; a plurality of high level lines; a metal block, located on the substrate and electrically connected to the high level lines, so that the high level lines at the same high level; wherein the data lines are electrically connected to driver chip through the area which the metal block is located in, and an insulating layer exists between the metal block and the data lines, a hollow area located in the metal block overlaps the data lines to reduce parasitic capacitance formed by the metal block and the data lines. This disclosure also discloses an AMOLED display device. Impact of resistor-capacitor delay and damage to components can be reduced by using this disclosure.
