A touch apparatus including a first substrate, a touch sensing structure, an insulation layer, a driving electrode, an electrochromic layer, a reflective electrode and a second substrate stacked sequentially along a direction is provided. The driving electrode and the reflective electrode are used to drive the electrochromic layer. The driving electrode is contacted with the insulation layer. The insulation layer has a thickness T 1 in the direction. The first substrate has a thickness T 2 in the direction.n n T 1<( T 2/10). |
