Abstract

A liquid crystal display device whose architrave area is reduced by reducing a distance between input and output terminals of each tape carrier package for supplying driving voltages to the liquid crystal display device is provided. The liquid crystal display device to which the present invention is applied comprises a liquid crystal display panel, a plurality of tape carrier packages provided around the liquid crystal display panel and a circuit board connected to each tape carrier package. Each tape carrier package comprises a semiconductor chip having a plurality of input terminals and a plurality of output terminals and a film having an opening at the middle thereof and provided, at the opening thereof, with a plurality of input side wires to be connected to the plurality of input terminals of the semiconductor chip and a plurality of output side wires to be connected to the plurality of output terminals of the semiconductor chip. A distance between the input terminals and the output terminals is reduced by disposing a plurality of kinds of functional element blocks within the semiconductor chip so that a part is created through which an imaging data signal input from the input…
