An image display device includes: a signal generation part which outputs an image signal corresponding to a gradation level of a pixel which constitutes an image; a laser beam source which radiates a laser beam having intensity corresponding to the image signal; and a signal adjustment part which superposes a high-frequency signal to the image signal inputted to the laser beam source. The signal adjustment part superposes a high-frequency signal which has amplitude not less than a width of a kink region where an input-output characteristic of the laser beam source changes most steeply on the image signal.

In an electronic apparatus, a display panel and a control board which controls driving of the display panel are connected to each other via a flexible cable. The flexible cable is constituted of a first folding portion which is pulled out from the display panel and is folded; a first extending portion which extends from the first folding portion between and along the display panel and a metal-made support plate which embraces the display panel from below; a second folding portion which extends from the first extending portion and is further folded through an opening formed in the support plate; and a second extending portion which extends from the second folding portion and along a back surface of the support plate, and has a distal end portion thereof connected to the control board.

There is provided a radio-frequency communication device that can sufficiently eliminate a leakage signal from a transmission side included in a received signal. The communication device includes a cancel amplitude controlling unit 62 selectively suppressing supply of a cancel signal to a cancel signal synthesizing unit 52, a received-signal terminating unit 50 selectively terminating a received-signal input terminal 64i, a signal strength detecting unit 78 detecting a signal strength, a memory unit 82 storing a signal strength detected by the signal strength detecting unit 78, a signal strength comparing unit 80 comparing a plurality kinds of signal strengths read out from the memory unit 82, and a cancel signal controlling unit 72 controlling an amplitude and/or a phase of the cancel signal based on a result of the comparison by the signal strength comparing unit 80. Thus, suppressing the cancel signal by the cancel amplitude controlling unit 62 enables accurate detection of a strength of the received signal, as well as terminating the received signal by the received-signal terminating unit 50 enables accurate detection of a strength of the cancel signal.
