Abstract:
A liquid crystal display device, comprising:a liquid crystal display panel having, a pair of substrates arranged to oppose each other, a liquid crystal layer interposed between the pair of substrates, a plurality of pixels being formed along the liquid crystal layer; a plurality of driving circuits for supplying signals to the pixels and being juxtaposed along one of edges of the liquid crystal display panel, the plurality of driving circuits being arranged adjacent one another and divided into a plurality of driving circuits groups having plural driving circuits along the one of the edges of the liquid crystal panel; a printed circuit board having a control circuit mounted thereon which controls the plurality of driving circuits; and a plurality of flexible wiring boards being juxtaposed along a direction in which the plurality of driving circuits are juxtaposed, a respective one of the plurality of flexible wiring boards being provided for a respective one of the plurality of driving circuits groups, each of the plurality of flexible wiring boards having a connecting portion to be connected to the printed circuit board and protruded portions provided in correspondence with respective driving circuits of a respective driving circuits group, the protruded portions being spaced from one another and protruding toward the one of the edges of the liquid crystal display panel and having respective ends mounted on one of the pair of substrates at the one of the edges of the liquid crystal display panel, wherein each of the plurality of flexible wiring boards receives a control signal from the control circuit through the connecting portion thereof and inputs the control signal sequentially to respective input sides of the respective driving circuits of the respective one of the driving circuit groups corresponding thereto, and each of the protruded portions thereof having at least one signal path thereof inputting the control signal to the input side of the driving circuits of the respective one of the driving circuits groups.
