PROBLEM TO BE SOLVED: To integrally form a plane antenna on the displaying surface of a liquid crystal panel. SOLUTION: The plane antenna of a liquid crystal display device 130 provided with the plane antenna having a microstrip structure is integrally formed with the color TFT(thin film transistor) liquid crystal display of the device 130. Specifically, the conductor wiring of a black matrix 132 is used as an antenna element and a metallic reflecting plate on the back of back light is utilized as a high-frequency ground. The conductor wiring forming the light shielding surface of the black matrix 132 is divided into the plane antenna and an outer peripheral section by a high-frequency insulating section which is arranged along the contour line of the antenna and intercepts signals having the resonance frequency of the antenna.
