A touch display device is provided. The touch display device includes a first substrate having at least one pixel unit, wherein the pixel unit includes a non-light-shielding region and a light-shielding region and includes a transistor disposed over the first substrate and a first insulating layer disposed over the first substrate and disposed over the transistor. The pixel unit further includes a touch signal line disposed over the first insulating layer and a second insulating layer disposed over the first insulating layer and the touch signal line. The second insulating layer has a recess corresponding to the non-light-shielding region. The pixel unit further includes a first electrode disposed over the second insulating layer and disposed in the recess. The touch display device further includes a second substrate disposed opposite the first substrate and a display medium disposed between the first substrate and the second substrate.
