Abstract

The invention discloses a touch-control liquid crystal display device, which comprises a liquid display unit, a touch-control panel and a second polarizer, wherein the liquid crystal display unit comprises a lower substrate, an upper substrate, a liquid crystal layer and a first polarizer; the upper substrate is arranged opposite to the lower substrate; the liquid crystal layer is arranged between the lower substrate and the upper substrate; the first polarizer is arranged on the lower substrate; the touch-control panel is arranged opposite to the liquid crystal display unit; and the second polarizer is arranged on the touch-control panel and is positioned between the liquid crystal display unit and the touch-control panel. Because of the low intensity of the reflected light generated in the touch-control liquid crystal display device, the device can provide good contrast degree and visibility.
