Method of manufacturing element substrate

摘要

A method of manufacturing an array substrate 20 according to the present invention includes a line forming step, and line forming step includes following performances. A plurality of source lines 27 are formed on a glass substrate GS so as to extend from a first region A1 on the glass substrate GS to a second region A2 that is adjacent to the first region on an outer side thereof. A plurality of source driver side check lines 45A are formed on the glass substrate GS so as to extend from the second region A2 to a third region that is adjacent to the first region A1 on an outer side thereof and adjacent to the second region A2. A plurality of first line connection portions 49 are formed in the second region A2 and the first line connection portions 49 connect the source lines 27 and the first source driver side check lines 45A. A capacity stem line 43 and a common line 44 are formed to extend from the first region A1 to the third region A3. A second source driver side check line 45B and a second line connection portion 50 that connects each of the capacity stem line 43 and the common line 44 and the source driver side check line 45B are formed in the third region A3.

1. A method of manufacturing an element substrate comprising:
a line forming step of forming lines on a substrate, the line forming step including:
forming a plurality of first lines extending from a first region of the substrate to a second region that is adjacent to the first region on an outer side of the first region;forming a plurality of first check lines extending from the second region to a third region that is adjacent to the first region on the outer side of the first region and adjacent to the second region;forming a plurality of first line connection portions in the second region, the first line connection portions connecting the first lines and the first check lines;forming a second line extending from the first region to the third region; and
forming a second check line and a second line connection portion in the third region, the second line connection portion connecting the second line and the second check line; a checking step of inputting a check signal to the plurality of first check lines and the second check line and checking the plurality of first lines and the second line; and a removing step of removing at least a part of one of the first check line and the second check line in the second region and the third region and disconnecting the first line and the first check line and disconnecting the second line and the second check line; wherein in the line forming step,
the first check lines are formed of a same material and formed in a same layer, andthe second check line is formed of a material different from the first check line and is formed in a layer different from a layer in which the first check line is formed with having an insulation layer between the second check line and the first check line.
