Abstract: The present disclosure provides an array substrate and a method for fabricating the same, a method for detecting alignment accuracy, and a liquid crystal display panel, wherein a dummy color resist unit is disposed on a periphery of a display area of a substrate, and a side or a center point of the dummy color resist unit is designed to be at a predetermined distance from an adjacent signal line. Therefore, it is only necessary to measure a distance between the side or the center point of the dummy color resist unit and a signal line adjacent to it, and compare the measured distance with the predetermined distance to estimate alignment accuracy of color resist units. It is not necessary to dispose detection units in a non-display area of the array substrate so that an area of the non-display area can be reduced to achieve ultra-narrow frame design.
