PROBLEM TO BE SOLVED: To display read information on the surface of the tag where the information is read and written without contacting. SOLUTION: A liquid crystal display part 1 is arranged between a transparent upper substrate 21 and an opaque lower substrate 22. An antenna 2 is wired beneath the upper substrate 21 while surrounding the outer periphery of the liquid crystal part 1. A communication IC 26 is formed beneath the upper substrate 21 while connected to the antenna 2. A liquid crystal circuit board 23 is embedded in a recessed part 22A of the lower substrate 22 and on the liquid crystal circuit board 23, a liquid crystal circuit board 24 and a liquid crystal tab 25 are stacked. Further, a both-sided adhesive tape is adhered to the reverse of the lower substrate 22. |
