A liquid crystal display includes pixels each having an switching element, drain drivers and gate drivers for operating the switching elements and the pixels, and drain lines and gate lines supplying signals from the drain drivers and the gate drivers to the switching elements being formed on one of a pair of substrates sandwiching a liquid crystal layer. Wiring lines are formed on the one of a pair of substrates for transferring display data signals and a clock signal to the gate drivers.

Driving method for display device

In a liquid crystal display comprising a plurality of pixels each of which has an switching element, a plurality of drain drivers and gate drivers for operating the switching elements and the pixels, and a plurality of drain lines and gate lines supplying signals from the drain drivers and the gate drivers to the switching elements being formed on one of a pair of substrates sandwiching a liquid crystal layer, the present invention provides wiring lines formed on the one of a pair of substrates for transferring display data signals and a clock signal between each pair of the plurality of drain drivers adjacent to one another, and provides at least one gate circuit for at least one of the plurality of drain drivers which is controlled by the clock signal and switches the display data signals and the clock signal either (1) to be acquired by the at least one of the plurality of drain drivers or (2) to be transferred to another of the plurality of drain drivers arranged adjacent to the at least one of the plurality of drain drivers. This liquid crystal display device has an advantage, for instance, or of suppressing electromagnetic interference (EMI) to another equipment surrounding the liquid crystal display device, of preventing the display data signals or the clock signal from being distorted in the wiring lines.
