Abstract
A touch display device including a first substrate, a second substrate, a display medium layer, a pixel array structure and a pressure sensing electrode layer is provided. The display medium layer is disposed between the first substrate and the second substrate. The pixel array structure is disposed between the second substrate and the display medium layer and includes a plurality of pixel electrodes and a multi-function electrode layer overlapping the pixel electrodes. The pressure sensing electrode layer is parallel to the multi-function electrode layer and a changeable gap is formed between the pressure sensing electrode layer and the multi-function electrode layer. The touch display device capable of 3D touch is provided.
