An embedded touch display device includes a first substrate (100) and a second substrate (200) which are opposite; a liquid crystal display unit and a capacitive touch unit located between the first substrate and the second substrate. The liquid crystal display structure includes a pixel electrode layer (120), a common electrode layer and a liquid crystal layer (30), the pixel electrode layer (120) and the common electrode layer are located on two sides of the liquid crystal layer (30), and liquid crystal (30) in the liquid crystal layer (30) is ferroelectric liquid crystal. Nematic liquid crystal is replaced with ferroelectric liquid crystal in the embedded touch display device, thereby solving a problem that in a TN mode embedded touch display device, liquid crystal molecules rotate from a horizontal direction to a vertical direction or from a vertical direction to a horizontal direction, thus the rotational angle is large, which results a great variation of permittivity of the liquid crystal layer, and thus seriously affects the sensitivity effect of the touch electrodes. |
