Driving circuit mounting film
A driving circuit mounting film according to an embodiment includes: a base film that has a first surface and a second surface facing each other with a thickness therebetween; a driving circuit portion that is on the first surface of the base film; a plurality of first signal lines that are on a first side region on one side of the driving circuit portion along a first direction; and a plurality of second signal lines that are on a second side region on the opposite side of the driving circuit portion along the first direction. A first width of the first side region and a second width of the second side region are different from each other, and the first signal line includes a first portion on the first surface of the base film and a second portion on the second surface of the base film.
1 . A driving circuit mounting film, comprising:
a base film that has a first surface and a second surface opposing each other with a thickness therebetween;
a driving circuit portion on the first surface of the base film;
a plurality of first signal lines on a first side region on one side of the driving circuit portion along a first direction; and
a plurality of second signal lines on a second side region on the opposite side of the driving circuit portion along the first direction,
wherein a first width of the first side region is greater than a second width of the second side region,
the plurality of first signal lines include first portions on the first surface of the base film and second portions on the second surface of the base film, and
the first portions and the second portions of the plurality of first signal lines are connected to each other through a plurality of holes in the first side region of the base film.
2 . The driving circuit mounting film of claim 1 , wherein the plurality of first signal lines and the plurality of second signal lines are not connected to the driving circuit portion.
3 . The driving circuit mounting film of claim 1 , wherein the plurality of second signal lines are disposed only on the first surface of the base film.
4 . The driving circuit mounting film of claim 1 , wherein among the first side region and the second side region, the plurality of holes are disposed only in the first side region.
5 . The driving circuit mounting film of claim 1 , wherein the plurality of holes are disposed along a direction parallel to the first direction.
6 . The driving circuit mounting film of claim 5 , wherein a virtual first line passing through the plurality of holes is a straight line parallel to the first direction.
7 . The driving circuit mounting film of claim 1 , wherein the plurality of holes are disposed along an oblique direction with respect to the first direction.
8 . The driving circuit mounting film of claim 7 , wherein a virtual second line passing through the plurality of holes is a straight line parallel to the oblique direction.
9 . The driving circuit mounting film of claim 1 , wherein the plurality of holes are not disposed in a line.
10 . The driving circuit mounting film of claim 9 , wherein a virtual third line passing through the plurality of holes is not a straight line.
11 . The driving circuit mounting film of claim 1 , wherein the number of the plurality of first signal lines is different from the number of the plurality of second signal lines.
12 . The driving circuit mounting film of claim 11 , wherein the number of the plurality of first signal lines is greater than the number of the plurality of second signal lines.
13 . The driving circuit mounting film of claim 1 , wherein the first width is about 1.5 times to about 4.5 times the second width.
14 . The driving circuit mounting film of claim 13 , wherein the first width is about three times the second width.
15 . The driving circuit mounting film of claim 1 , further comprising a plurality of third signal lines disposed on the first surface of the base film and connected to the driving circuit portion.
16 . The driving circuit mounting film of claim 1 , wherein the plurality of second signal lines are disposed only on the first surface of the base film among the first surface and the second surface of the base film.
