The invention discloses a touch display screen and a touch
display device. The touch display screen comprises an array substrate, a
color film substrate, a group of first
electrode lines, a group of second
electrode lines and high-resistance transparent conductive shielding
layers, wherein the array substrate and the
color film substrate are symmetrically arranged; the group of first
electrode lines is arranged on the array substrate or the
color film substrate; the group of second electrode lines is arranged on the array substrate or the color film substrate and is in intersection arrangement with the group of first electrode lines; and the high-resistance transparent conductive shielding
layers are arranged on the color film substrate and are positioned on the group of first electrode lines and the group of second electrode lines. The resistance value of the high-resistance transparent conductive shielding
layers is higher, thus projection
electric field signals between the first electrode lines and the second electrode lines can pass through the high-resistance transparent conductive shielding layers, and the implementability of touch operation is ensured; and in addition, the transparent conductive shielding layers per se have
conductivity, when a display screen is touched by external
static electricity, electrostatic charges can be quickly led out and connected with the ground by the transparent conductive shielding layers, the electrostatic damage to the display screen due to the electrostatic charges can be prevented, and the display effect is further increased.
