Abstract
A in-cell touch-sensitive liquid crystal display device (LCD) includes a first substrate, a second substrate opposite to the first substrate, a liquid crystal layer disposed between the first substrate and the second substrate, a first sensing line and a second sensing line disposed on the second substrate, a first conductive layer and a second conductive layer electrically connected to the first sensing line and the second sensing line, respectively, and electrically isolated from each other by a gap existing therebetween. The in-cell touch-sensitive LCD device further includes a spacer disposed on the first substrate and corresponding to the gap. The spacer is electrically connected to the first conductive layer and the second conductive layer in response to an external pressure.
