1. A display device comprising:
- a plurality of drain lines and a plurality of gate lines intersecting with the drain lines on a substrate;
regions surrounded by the drain lines and the gate lines as regions of pixels;
wherein a non-display region where the drain lines, the gate lines and the pixels are not formed is formed at a portion within a display region which is constituted of a mass of the pixels,drain route-around lines and gate route-around lines are formed by routing the drain lines and the gate lines separated by the non-display region around the non-display region,a line width of at least one of the drain route-around line and the gate route-around line is set such that the line width at an intersecting portion where the drain route-around line and the gate route-around line intersect with each other differs from the line width at a non-intersecting portion, andassuming the line width of the drain line at the non-intersecting portion as a1, the line width of the drain line at the intersecting portion as b1, the line width of the drain route-around line at the non-intersecting portion as c1, the line width of the drain route-around line at the intersecting portion as d1, the line width of the gate line at the non-intersecting portion as a2, the line width of the gate line at the intersecting portion as b2, the line width of the gate route-around line at the non-intersecting portion as c2, and the line width of the gate route-around line at the intersecting portion as d2, a relationship of |a1−

Abstract
A display device in which a non-display region where drain lines, gate lines and pixels are not formed is formed at a portion within a display region which is constituted of a mass of the pixels, drain route-around lines and gate route-around lines are formed by routing the drain lines and the gate lines separated by the non-display region around the non-display region, a line width of at least one of the drain route-around line and the gate route-around line is set such that the line width at an intersecting portion where the drain route-around line and the gate route-around line intersect with each other differs from the line width at a non-intersecting portion.
