Abstract
A touch liquid crystal display (LCD) device, a touch display device and a lamination method are provided. The touch LCD device includes an LCD module, a package substrate, a first adhesive and a second adhesive; the LCD module and the package substrate are adhered to each other through the first adhesive which covers a display area of the LCD module; and the second adhesive is disposed between the LCD module and the package substrate and on a non-display area of the LCD module, and hardness of the second adhesive is greater than hardness of the first adhesive. The touch LCD device can effectively eliminate the problem of reduced display quality caused by the water wave phenomenon that the touch LCD device adopting a full lamination method tends to generate.
