摘要： A liquid crystal display device (100) according to the present invention includes a vertical alignment type liquid crystal layer (3); and a pair of optical alignment films (12, 22). A plurality of picture elements (R, G, B, Y) each include four liquid crystal domains (D1 through D4) in which tilt directions of liquid crystal molecules when a voltage is applied are different. The four liquid crystal domains are located in a matrix of 2 rows×2 columns. The pair of optical alignment films have such an alignment regulation force that causes an identical alignment pattern to appear in repetition in the liquid crystal layer along a first direction which is parallel to one of a row direction and a column direction, with 2n pixels (n is an integer of 1 or greater) being a minimum unit. In the 2n pixels which form the repeat unit of alignment pattern, there are first picture elements and second picture elements in a mixed state, the first picture elements each including the four liquid crystal domains located in a first order, and the second picture elements each including the four liquid crystal domains located in a second order which is different from the first order. According to the present invention, when the 4D-RTN mode is adopted for a liquid crystal display device in which one pixel includes a picture element having a different size from that of another picture element, increase of the cost and the time which are required for optical alignment processing can be suppressed.

摘要： In one embodiment of the present invention, each pixel includes first and second subpixels. CS bus lines connected to the respective storage capacitors of the first and second subpixels are electrically independent of each other. A CS voltage has a waveform that inverts its polarity at least once a frame, which includes a first subframe for sequentially scanning a series of odd rows and a second SF for sequentially scanning even rows that have been skipped during the first SF. A source signal voltage varies so as to have two frames or subframes with mutually opposite polarities. A CS voltage has a waveform that has quite opposite consequences on the effective voltage of a subpixel of a pixel connected to the jth scan line to be selected during the first subframe and on that of another subpixel of a pixel connected to the (j+1)th scan line to be selected during the second subframe. In this manner, the deterioration in display quality, which would be caused if either a source line inversion drive or a block inversion drive is applied to a multi-pixel technology, can be minimized.
