Abstract

A display panel includes a method of fabricating an array substrate. The method includes forming a metal layer () on a substrate, and patterning the metal layer () using a phase shift mask to form a pattern of metal wiring. The phase shift mask includes a substrate and a wiring light shielding portion () on the substrate (). The wiring light shielding portion () includes a light shielding region () and a phase shift region (). In a direction perpendicular to the extending direction of the wiring light shielding portion () a width of the light shielding region () is larger than a width of the pattern of the metal wiring formed by the wiring light shielding portion ().
