Abstract
A touch liquid crystal display device includes a first substrate and a second substrate opposite to each other, and a liquid crystal layer disposed between the first and second substrates. The first substrate includes a touch layer disposed on a surface of the first substrate facing the liquid crystal layer, an insulating layer disposed on a surface of the touch layer and covering the touch layer, and a pixel array structure disposed on a surface of the insulating layer facing away from the touch layer. The touch layer is disposed between the pixel array structure and the first substrate. Only a filming process and a photoetching process of the touch layer and a deposition process of the insulating layer are additionally required to transform a non-touch liquid crystal display device to a touch liquid crystal display device.
