    • An electronic component or display device of the present invention can be provided by using a following pattern formation method. On a substrate treated with a first etching with a first resist pattern as a first mask, a second resist pattern is transfer-printed on the first resist patterns so as to partially overlap with the first resist pattern and partially extended from the first resist pattern. And then a second etching is performed by using the first resist pattern and the second resist pattern as a second mask. The first resist pattern and the second resist pattern are used for forming wirings and/or terminals, and the extended portion of the second resist pattern is used to make the wirings to have a cross section of a stair-like edge shape.
