## Abstract

An active matrix substrate includes a plurality of signal lines, each of which includes first and second line portions and an inner connection portion (connection portion) that connects the first and second line portions. The first and second line portions of one of two adjacent signal lines are made of first and second conductive layers, respectively, and the first and second line portions of the other of the two adjacent signal lines are made of second and first conductive layers, respectively. The position of the connection portion of each of the signal lines is determined in accordance with the layout position of that signal line in the line region.

## Claims

### Claim 1

(canceled)

### Claim 2

An active matrix substrate comprising:
a plurality of data lines and a plurality of scanning lines that are arranged in a matrix;
a plurality of switching elements that are provided on each at a corresponding crossing of the plurality of data lines with the plurality of scanning lines; and
a plurality of pixels that include pixel electrodes connected to the plurality of switching elements,
wherein a plurality of terminals are provided to input external signals to the plurality of data lines or the plurality of scanning lines,
a plurality of signal lines are defined in a line region between a matrix region in which the plurality of data lines and the plurality of scanning lines are arranged in the matrix and a terminal region in which the plurality of terminals are arranged, and the line region is defined so that a line pitch becomes narrower in a direction from the matrix region to the terminal region,
one end of each of the plurality of signal lines is connected to drive the data line or the scanning line, and the other end is connected to one of the plurality of terminals,
each of the plurality of signal lines includes a first line portion provided on a matrix region side, a second line portion provided on a terminal region side, and a connection portion that connects the first line portion and the second line portion,
the first line portion and the second line portion of one of two adjacent signal lines of the plurality of signal lines are made of a first conductive layer and a second conductive layer, respectively, which are different from each other, and the first line portion and the second line portion of the other of the two adjacent signal lines are made of the second conductive layer and the first conductive layer, respectively,
a position of the connection portion of each of the plurality of signal lines is determined in accordance with a layout position of the respective signal line in the line region, and
the plurality of signal lines include a line group in which the signal lines are connected to the terminals by bending the second line portions so that a pitch of the second line portions is represented by Pbo, and a line group in which the signal lines are connected to the terminals by bending the first line portions so that a pitch of the second line portions is represented by Pco.
