ABSTRACT:
A liquid crystal display with an IC tag in which information of an IC chip can be read from the surface of the liquid crystal display, while the IC chip can be mounted on the small-size liquid crystal display without lowering the attraction of design thereof. A common electrode is formed in a wide region of an upper electrode layer constituting the liquid crystal display. Antennas are formed in a region of an edge portion of the upper electrode layer where the common electrode is not formed, and within the region of a surface-side glass. An IC chip is placed out of the region of the surface-side glass. X-axis and Y-axis matrix electrodes are formed in a region of a lower electrode layer opposite to the common electrode.
