摘要： This is an active matrix liquid crystal display device comprising a capacitive accumulation portion formed by overlapping a pixel electrode, an insulating layer and a common electrode for each pixel area, and a non-electrode area in a part of the pixel area which is not covered with a pixel electrode, wherein a peripheral shape of said capacitive accumulation portion on a side contacting said non-electrode area is substantially the same between the respective pixels, and a value of a storage capacity in said capacitive accumulation portion differs on a feeding side and on a termination side, the value on the feeding side being larger than the value on the termination side. Thereby, a constant aperture ratio can be maintained by changing the storage capacity value for each pixel. Furthermore, by using a lateral electric field method liquid crystal display device, the storage capacity value can be changed while maintaining the aperture ratio of the pixel constant, and the electric fields applied to the liquid crystal layer in the display portion can be kept evenly. As a result, deterioration and unevenness of display characteristics do not occur. Moreover, even in the case of using a light shield film to improve contrast and so forth, a light shield film with a narrower width than that in a conventional configuration can be used, so that the aperture ratio does not drop drastically.

摘要： One of a pair of substrates with liquid crystals sandwiched therebetween includes a plurality of pixels each of which is provided with a scanning electrode, an image signal electrode, a switching element provided at an intersection of the scanning electrode and the image signal electrode, a pixel electrode connected to the image signal electrode via the switching element, a counter electrode, and a busbar electrically connected to the counter electrode. A portion of the pixel electrode is overlapped with the busbar so as to make up a storage capacitance. A shape of the pixel electrode is altered for each pixel so that a value of the storage capacitance becomes smaller from a feeding side to a termination side. The portion of the pixel electrode overlapped with the busbar so as to make up the storage capacitance is located within the busbar in a plan view of the device.

摘要： A liquid crystal display device includes liquid crystal pixels, signal line groups each including a predetermined number of signal lines, and a drive circuit which selects the pixels on a row-by-row basis and drives the pixels of the selected row via the signal lines. The drive circuit includes a signal line driver which outputs a predetermined number of pixel voltages for each group driving period while the pixels of each row are being selected, a multiplexer which distributes to each signal line group the pixel voltages output from the signal line driver, and a controller which controls the multiplexer to electrically connect all of the signal line groups to the signal line driver and electrically disconnect the signal line groups one by one from the signal line driver for each group driving period, in a selection period of the pixels of an initial row that requires polarity inversion.

摘要： A liquid crystal display panel of the invention is such that, in a pixel region defined by a region of the array substrate surrounded by a pair of image signal lines and a pair of scanning signal lines, of a line-shaped pixel electrode and a common electrode, the electrode that is disposed adjacent to and parallel to a signal line is made of an opaque conductor and at least one of the other electrodes is made of a transparent conductor. Adverse effects of the electric field formed between a signal line and an adjacent electrode thereto are suppressed and a sufficient aperture ratio is ensured by using a transparent conductor for the electrode contributing good display.
