| 1. A display device comprising:
a plurality of first electrode lines and a plurality of second electrode lines which are arranged above said plurality of
first electrode lines and intersected with said first electrode lines through an insulating film on a substrate, and a rectangular
display region is formed by said plurality of first electrode lines and said plurality of second electrode lines,
wherein at three arbitrary portions on said display region where said first electrode line and said second electrode line
intersect each other,
a film thickness and a width of a conductive film of said first electrode line in said first portion as t1 and w1, a film thickness and a width of a conductive film of said first electrode line in said second portion as t2 and w2, a film thickness and a width of a conductive film of said first electrode line in said third portion as t3 and w3, t1>t2>t3 and w1<w2<w3 to form a cross-sectional area t1×w1 of said first gate electrode line in said first portion, a cross-sectional area t2×w2 of said first gate electrode line in said second portion and a cross-sectional area t3×w3 of said first gate electrode line in said third portion substantially equal to one another, and
said first portion, said second portion and said third portion are formed in the same layer.
