Abstract

In a LCD device, at least two switching elements are connected to each of the pixel electrodes. A first switching element out of the two switching elements is connected to a first drain line which supplies display signals having a positive polarity. A second switching element out of the two switching elements is connected to a second drain line which supplies display signals having a negative polarity. A gate of the first switching element is connected to a corresponding one of odd-numbered gate lines, and a gate of the second switching element is connected to a corresponding one of even-numbered gate lines. The gate-scan driving circuit selectively drives the odd-numbered gate lines and the even-numbered gate lines, thereby directions of electric fields acting upon liquid crystals are inverted without changing the polarities of the display signals.

Description

technical field [0001] The invention relates to a liquid crystal display device. In particular, the invention relates to a liquid crystal display device with reduced power consumption. Background technique [0002] As display devices for audio-visual (AV) equipment and office automation (OA) equipment, liquid crystal display (LCD) devices have been widely used due to their advantages of thin thickness, light weight, low power consumption, and the like. [0003] In other words, display devices for personal computers, televisions, etc. and display devices for electronic computers, mobile televisions, mobile phones, mobile facsimiles, etc. are expected to be small in size and light in weight. In addition, it is desirable that these devices consume low power because when carrying them, they need to use batteries to operate. [0004] As display devices with low power consumption, for example, LCD devices are known. [0005] That is, it is also recognized that LCD devices are m...
