Substrate for a display panel, a display panel having the substrate, a method of producing the substrate, and a method of producing the display panel

A production method of a substrate for a display panel comprising the steps of:

• forming markings each provided to thin film patterns, wherein the markings have shapes different from each other to distinguish between boundary positions of divided exposure regions of respective thin film patterns, and wherein the markings indicate the boundary positions of the divided exposure regions of the respective thin film patterns, the markings for each exposure region include a center marking and edge markings, having a same shape as the center marking, provided on each side of the center marking for defining a boundary position between the edge markings;
• and
• locating the boundary positions of the divided exposure regions of the respective thin film patterns based on the markings.

A production method of a substrate for a display panel comprising the steps of:

• forming markings indicating boundary positions of divided exposure regions on at least one of two or more thin film patterns formed by divisional exposure by which a region to be exposed is divided into a plurality of exposure regions and exposure is made on each of the divided exposure regions, the markings each provided to the thin film patterns, wherein the markings have shapes different from each other to distinguish between the boundary positions of the divided exposure regions of the respective thin film patterns, the markings for each exposure region include a center marking and edge markings, having a same shape as the center marking, provided on each side of the center marking for defining a boundary position between the edge markings, and wherein the boundary positions of the divided exposure regions of the two or more thin film patterns do not coincide with each other;
• and
• locating the boundary positions of the divided exposure regions of the respective thin film patterns based on the markings.
