A display device has a laminated body including a first glass substrate and a second glass substrate, and an inside frame for supporting the laminated body. A polarizing plate is provided on a first surface as one main surface of the first glass substrate, and a part of a second surface as one main surface of the second glass substrate faces a third surface as the other surface of the first glass substrate via a liquid crystal member. And a driver for controlling the liquid crystal is provided at the non-face-to-face area of the end of the second surface where the second surface does not face the third surface. An inside frame has a fifth surface which faces a fourth surface as the other main surface of the second glass substrate via the polarizing plate, and is formed with a notch at the end of the fifth surface on the side of the non-face-to-face area.

A first housing 14 is provided with a first and a second terminals 11a, 11b to be connected with a first and a second external antennas. A second housing 13 is connected via a coaxial cable 9 with the first housing 14. The first housing 14 includes a switch 10 connected via a capacitor 3b with the coaxial cable, for selectively connecting one of the first and second terminals 11a, 11b which provides higher receipt sensitivity on the basis of a switching signal and a DC power supply 12 connected via an inductance 4b to the coaxial cable 9. The second housing 13 includes a radio circuit 2 connected via the capacitance 3a with the coaxial cable 9, for processing a radio signal to be transmitted, supplying the processed radio signals to the first or second internal antenna 7 or 8 and processing the received radio signal. A control circuit 1 is connected via the inductance 4a to the coaxial cable 9 for outputting the switching signal on the basis of the received signal level by the external antenna and an inductance connected between the coaxial cable and a circuit required to be supplied with the DC power supply. Thus the radio signal is transmitted/received and the DC power is supplied via the coaxial cable 9.

A protective film for polarizing plate is disclosed in which an contact angle of the surface in contact with a polarizer with respect to pure water is less than 55° and the surface in contact with a polarizer becomes hydrophilic due to a plasma treatment.In such a manner, the protective film for the polarizing plate is readily adhered with a polyvinyl alcohol film employed as a polarizer and can be produced employing processing which is safe in work and does not adversely affect the environment. Thus highly efficient protective film for the polarizing plate, which exhibits excellent adhesion with a polyvinyl alcohol film, and a polarizing plate employing the same, are provided.
