Abstract:
1. A liquid crystal display device comprising: a plurality of pixel electrodes, which are arranged in columns and rows, each said pixel electrode including a reflective electrode region; a plurality of scanning lines, which extends in a row direction; a plurality of signal lines, which extends in a column direction; a plurality of switching elements, each said switching element being provided for an associated one of the pixel electrodes and being connected to the associated pixel electrode, an associated one of the scanning lines and an associated one of the signal lines; a liquid crystal layer; and at least one counter electrode, which faces the pixel electrodes by way of the liquid crystal layer, the liquid crystal display device sequentially supplying a scanning signal voltage to one of the scanning lines after another to select one group of pixel electrodes, which are connected to the same one of the scanning lines, after another from the pixel electrodes, and then supplying display signal voltages to the selected group of pixel electrodes by way of the signal lines, thereby displaying an image thereon, wherein the pixel electrodes are arranged in such a manner that the polarity of a voltage to be applied to the liquid crystal layer is inverted for every predetermined number of pixel electrodes in each of the rows and in each of the columns, and wherein the display signal voltage to be supplied to each said pixel electrode is updated at a frequency of 45 Hz or less, wherein each said pixel electrode includes the reflective electrode region and a transmissive electrode region, wherein the switching elements that are connected to one of the scanning lines include: a first group of switching elements, which are connected to the pixel electrodes belonging to one of the rows that is adjacent to, and located over, the scanning line; and a second group of switching elements, which are connected to the pixel electrodes belonging to one of the rows that is adjacent to, and located under, the scanning line, the first and second groups of switching elements being arranged along the scanning line such that every predetermined number of switching elements of the first group are followed by every predetermined number of switching elements of the second group, and wherein a distance from each said switching element of the first group to a geometric center of mass of the transmissive electrode region of the pixel electrode that is connected to the switching element of the first group is different from a distance from each said switching element of the second group to a geometric center of mass of the transmissive electrode region of the pixel electrode that is connected to the switching element of the second group.
