A sensing display apparatus includes a pixel array substrate, a sensing device substrate, and a display medium layer. The sensing device substrate includes a first substrate, a sensing device, first to third signal lines, and a shielding layer. The sensing device includes a first switching element electrically connected with the first and second signal lines, an electrically conductive layer electrically connected with the third signal line, an electrode layer electrically connected with the first switching element and a photo-sensitive layer disposed between the electrically conductive layer and the electrode layer. The shielding layer is disposed between the first to third signal lines and the pixel array substrate. The sensing display apparatus has light transmitting regions and a light shielding region surrounding the light transmitting regions. The sensing device and the first to third signal lines are disposed in the light shielding region.
