Touch control display device

A touch control display device comprises the following elements: a display module containing a plurality of first sub-pixels, second sub-pixels and third sub-pixels in different colors; a plurality of touch control units arranged on the display module, wherein each touch control unit comprises the following elements: two first electrode pieces arranged in a first direction; two electrically connected second electrode pieces arranged in a second direction; a bridging line electrically connected with the two first electrode pieces, and the bridging line has an angle (theta1) bigger than zero relative to the first direction; an insulation layer arranged between the bridging line and the two second electrode pieces. Two adjacent bridging lines along the first direction are symmetrically arranged around an axis parallel to the second direction; the two adjacent bridging lines along the second direction are symmetrically arranged around an axis parallel to the first direction.
