A liquid crystal display panel includes: a pair of substrates; a cylindrical spacer configured to hold a gap between the pair of substrates, and a liquid crystal which fills the gap. The cylindrical spacer includes a first support portion having a first support surface and a second support portion having a second support surface. The first support portion is provided inside the second support surface so that the first support surface is projected from the second support surface. The second support portion is provided on a major surface of one of the substrates the second support surface from the major surface.

When performing radio communication with a reader/writer (1), supply of a power source S4 from a battery (14) is started when a level judgment circuit (9) judges that the signal level of a reception signal S2 received by an antenna (5) of a noncontact data carrier (4) is equal to or higher than a predetermined amplitude and a timer circuit (10) judges that the state where the amplitude is equal to or higher than the predetermined value has continued for a predetermined period T1 or more, and further, the supply of the power source S4 from the battery is stopped when the level judgment circuit (9) judges that the signal level of the reception signal S2 is lower than the predetermined amplitude and the timer circuit (10) judges that state where the amplitude is lower than the predetermined value has continued for a predetermined period T2 or more, thereby ensuring communication reliability that causes no problem in practical use of the noncontact data carrier (4), and avoiding insignificant dissipation of the battery.
