Abstract
Official abstract text for this publication.
A liquid crystal display has touch a sensing layer disposed above an image forming part. The liquid crystal display includes: a lower panel including a first substrate and a plurality of gate lines and a plurality of data lines formed on the first substrate; an upper panel including a second substrate, a first sensing unit formed on the second substrate, a source voltage line, a bias voltage line, and first and second sensing data lines that are respectively formed on opposed longitudinal sides of one of the source voltage line or the bias voltage line; and a liquid crystal layer interposed between the lower panel and the upper panel, wherein the first sensing unit includes a switching transistor electrically connected to one of the first sensing data line and the second sensing data line and a sensing transistor electrically connected to the source voltage line and the bias voltage line, the source voltage line and the sensing data line extend longitudinally in the same direction as a plurality of data lines, and the source voltage line or the bias voltage line overlaps directly above a corresponding data line among a plurality of data lines.
First claim
