Abstract
The present disclosure provides a touch liquid crystal display device, a liquid crystal display panel, an array substrate and a color film substrate, and belongs to the field of liquid crystal display. The touch liquid crystal display panel includes an array substrate and a color film substrate, on said array substrate is formed a GOA circuit, and at the outer side of said color film substrate is formed a touch signal transmission line. The touch liquid crystal display panel further comprises a shielding electrode located between said GOA circuit and said touch signal transmission line, said shielding electrode being used for shielding the interference caused by the clock signal of said GOA circuit to the touch sensing signal on said touch signal transmission line. The present disclosure can reduce the interference caused by the clock signal of said GOA circuit to the touch sensing signal on said touch signal transmission line.
