An image display device includes a display panel having plural pixels and a second board having a transmitting electrode, the display panel having a first substrate that is disposed so as to overlap the second board, each pixel having a pixel electrode and a counter electrode, and the counter electrode being formed in a planar shape and being commonly provided to the pixel electrodes of each pixel; the counter electrode being divided into a portion A corresponding to the transmitting electrode of the second board and a portion B other than it, and the portions A and B of the counter electrode being connected to a common voltage through resistors. The portion A of the counter electrode constitutes the receiving electrode, and the portion A of the counter electrode acting as the receiving electrode is connected to a receiving circuit in the display panel through a decoupling capacitor.
