LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device comprising:
- an active matrix substrate including a plurality of first display lines provided so as to extend parallel to each other, and a plurality of second display lines provided so as to extend parallel to each other in a direction crossing the first display lines;
a counter substrate placed opposing the active matrix substrate and including a black matrix provided so as to overlap the first display lines and the second display lines; and
a liquid crystal layer provided between the active matrix substrate and the counter substrate, whereinthe active matrix substrate includes a plurality of touch panel lines provided so as to extend parallel to each other in a direction in which the first display lines extend, andportions of the black matrix overlapping the second display lines are electrically conductive and are configured so as to come into contact with the touch panel lines when a surface of the active matrix substrate or the counter substrate is pressed.

Abstract
A device includes: an active matrix substrate (20a) including a plurality of first display lines (11a) extending parallel to each other and a plurality of second display lines extending parallel to each other in a direction crossing the first display lines (11a); and a counter substrate (30a) including a black matrix (B) provided so as to overlap the first display lines (11a) and the second display lines, wherein the active matrix substrate (20a) includes a plurality of touch panel lines (11b) extending parallel to each other in a direction in which the first display lines (11a) extend, and portions of the black matrix (B) overlapping the second display lines are electrically conductive and are configured so as to come into contact with the touch panel lines (11b) when the surface of the active matrix substrate (20a) or the counter substrate (30a) is pressed.
