The invention discloses an image display system which comprises a touch sensing device. The touch sensing device comprises a plurality of sensing units arranged to form an array, each sensing unit comprises a pair of first transparent electrode layers and a pair of second transparent electrode layers, each pair of first transparent electrode layers is arranged along a first direction, and each pair of second transparent electrode layers is adjacent to the corresponding pair of first transparent electrode layers and is arranged along a second direction. The first direction is intersected with the second direction, and at least one edge of the contour of each of the first transparent electrode layers and the second transparent electrode layers is nonlinear.
