Touch display apparatus with anti-peeping technology

A touch display apparatus, comprising:

• a first substrate, having a first surface and a second surface, wherein a plurality of opening areas and a non-opening area are defined on the second surface, and the non-opening area is defined as surrounding the opening areas, the first substrate comprising:
• a black matrix layer, disposed on the second surface of the first substrate and corresponding to the non-opening area;
• a color filter layer, disposed on the second surface of the first substrate;
• a protection layer, covering the black matrix layer and the second surface of the first substrate;
• a touch electrode layer, disposed at least on the protection layer and corresponding to the non-opening area;
• a first flat layer, covering the protection layer and the touch electrode layer, wherein the touch electrode layer is disposed between the protection layer and the first flat layer;
• a patterned viewing angle control transparent electrode layer, disposed on the first flat layer, the patterned viewing angle control transparent electrode layer having a plurality of control electrode members, a plurality of first connection electrode members, a plurality of second connection electrode members, and a plurality of transparent bridging lines, wherein the control electrode members are disposed corresponding to the opening areas, the first connection electrode members are disposed corresponding to the non-opening area and extending in a first direction and are electrically connected to the control electrode members, the second connection electrode members are disposed corresponding to the non-opening area and extending in a second direction and are electrically connected to the first connection electrode members, and the transparent bridging lines are disposed between any adjacent two of the first connection electrode members and are electrically connected to the touch electrode layer;
• and
• a second flat layer, disposed on the patterned viewing angle control transparent electrode layer;
• a second substrate, disposed opposite to the second surface of the first substrate, wherein the second substrate has a side facing to the second surface of the first substrate, and comprises a pixel electrode layer, an insulator layer, and a common electrode layer that are disposed on the side, and the insulator layer is disposed between the pixel electrode layer and the common electrode layer;
• and
• a liquid crystal (LC) layer, disposed between the second flat layer of the first substrate and the second substrate.
