Problems solved by technology

[0006] However, the cost of the anti-reflection film 160 is higher
In addition, when attaching the anti-reflection film 160, problems such as contamination of the anti-reflection film 160 or poor attachment are often caused by residual adhesive (not shown) around the periphery.

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.

Description

technical field [0001] The present invention relates to a touch display device (Touch Display) and a manufacturing method thereof, and in particular to a touch display device (LCD with a built-in touch panel) having good contrast and visibility ) and methods of manufacture thereof. Background technique [0002] A touch panel is a human-machine interface that has been widely accepted by the public. The touch panel can be assembled on various types of flat-panel displays, so that the flat-panel displays can display pictures and input operation information. [0003] figure 1 It is a schematic diagram of an existing touch-type liquid crystal display device. Please refer to figure 1 , the touch-sensitive liquid crystal display device 100 includes: a liquid crystal display panel 110 and a touch panel 120, wherein the liquid crystal display panel 110 includes: a first polarizer 111, a lower substrate 112, an active element array 113, a liquid crystal layer 114, and a common ele...
