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 device includes a display portion having a first substrate, a second substrate opposing to the first substrate, a liquid crystal layer held between the first and second substrates, and a plurality of pixels arranged in a delta shape. A plurality of pixel electrodes are respectively connected to signal lines extending in a first direction via a switch. The switch is controlled by scanning lines extending in a second direction which orthogonally crosses the first direction. The signal lines extend in a space between the pixel electrodes in a meandering shape in the second direction, and two kinds of color pixels are connected with a common signal line in turn via the pixel switch.

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.
