Abstract
A touch display device is a layered structure, provided with a touch surface, and comprises two light energy filter layers. Each of the two light energy filter layers acts on different optical bands. One of the two light energy filter layers is closer to the touch surface. An optical band wavelength acted upon by one of the two light energy filter layers closer to the touch surface is smaller than an optical band wavelength acted upon by one of the two light energy filter layers farther from the touch surface. One of the two light energy filter layers closer to the touch surface provides protection for a touch portion and a display portion comprised in the layered structure, and one of the two light energy filter layers farther from the touch surface provides protection at least for the display portion comprised in the layered structure.
