摘要:
A portable display device, such as a contactless IC card, comprising, for example, cholesteric liquid crystal with a memory capability and having an improved mechanical durability. The display device has two opposed substrates (1) and display portion (liquid crystal) (2) interposed between the substrates (1). The display device further has a wall member (3) which is a wall structure holding the substrates at portions other than the display portion (2). The walls are perpendicular to the substrates (1), and the surfaces perpendicular to the walls are adhered to the substrates (1). The area of the surfaces adhered to the substrates (1) is larger than that of the surfaces of the display portion (2) opposing the substrates (1).

An IC card for transmitting information to an external device and/or receiving information from an external device, capable of displaying information effectively making the most use of the characteristics of cholesteric liquid crystal. The IC card comprises information display means for displaying predetermined information by transmitting/reflecting light by a method in which a stack of cholesteric liquid crystal layers (631, 632) reflecting red light while in the planar state and a cholesteric liquid crystal layer (633) reflecting blue light, and voltages are applied to the stacked cholesteric liquid crystal layers (631, 632, 633)respectively to change the aligned state of cholesteric liquid crystal molecules between the planar and focal conic states.

A system includes a display device (1) having no power source and an information display device (2) such as a radio terminal for transmitting display data and power to the display device (1). The display device (1) can be mechanically-detachably attached to the information display device (2). The device (1) has a display section (3) capable of continuing display even after power supply is cut off, a near-distance communication section (4) for receiving display data from outside, and a display control section (5) for the received data. The device (2) has a storage section (6) for storing display data and a communication section (7) for transmitting the display data to the device (1). For example, the device (2) further has a mechanical attachment/detachment section for mounting the device (1) on the device (2).
