Abstract
A multi-layer integrated circuit having through-hole inter-layer connections includes an integrally formed liquid crystal display panel, and performs all receiving, amplifying and video display functions of a TV receiver when connected to an antenna. Shield layers are incorporated to prevent transmission of interference from a display drive section of the integrated circuit to the antenna or the input stage of an I.F. amplifier section, and to prevent interference between the local oscillator of a tuner section and the I.F. amplifier.
