摘要:
A driving circuit of a liquid crystal display device includes driver output lines connected to outputs of a data line driver, m pieces of block selection signal lines for sequentially selecting m pieces of blocks, and data lines for supplying data to a display area. A switch sequentially connects an ith driver output line to ith, i+2jth, . . . , and i+2jx(m−1)th data lines in response to signals on the m pieces of block selection signal lines when j is a positive integer smaller than m.

A common electrode driving circuit is provided on a TFT substrate as a first substrate. Striped common electrodes are formed along the layout of pixels, such as data lines (or scanning lines), on a common substrate as a second substrate. The common electrode driving circuit inverts a common electrode voltage that is applied to a common electrode of an odd-number order, relative to a common electrode voltage that is applied to a common electrode of an even-number order. The common electrode driving circuit inverts these common electrode voltages to match the polarity inversion period at the same time. Based on this, a common inversion driving system is realized, and flicker is reduced according to a lengthwise line (or crosswise line) inversion driving system.

A reflective electrode, a transparent electrode, a TFT connected to the reflective electrode and a TFT connected to the transparent electrode are formed in each picture element. A first data signal is written into the reflective electrode via the TFT, a second data signal is written into the transparent electrode via the TFT. In this way, the individual data signals are respectively written into the reflective electrode and the transparent electrode, and thereby excellent display quality can be obtained either when used as a transmissive liquid crystal display device or when used as a reflective liquid crystal display device.
