In the liquid crystal display device (100) of this invention, pixels include m kinds of (where m is an even number and m≧4) pixels (R, G, B and Y) that display different colors. The pixels are arranged so that n of the m kinds of pixels (where n is an even number, n≦m and n is a divisor of m) are repeatedly arranged in the same order in the row direction. Each row of pixels formed by those pixels includes groups of pixels, to each of which n pixels arranged consecutively in the row direction belong. Grayscale voltages of opposite polarities are applied through associated signal lines (13) to the pixel electrodes (11) of two arbitrary adjacent pixels in each group of pixels. In two arbitrary groups of pixels that are adjacent in the row direction, grayscale voltages of opposite polarities are applied through their associated signal lines to the pixel electrodes of pixels that display the same color. The signal lines include at least one pair of adjacent signal lines (13p) to supply grayscale voltages of the same polarity. The source-drain capacitance of the pixels located between the pair of signal lines is smaller than that of the other pixels. The present invention can improve the display quality of a liquid crystal display device, of which each picture element is defined by an even number of pixels.

A liquid crystal display device includes a plurality of subpixels arranged in one column and n rows (where n is an even number ≧ four) within each pixel. In two of the pixels, which are adjacent to each other in the row direction, subpixels that represent the same color belong to the same row. If two of the pixels, which are adjacent to each other in the column direction, are called first and second pixels, respectively, a first half of the subpixels having a combination of first colors are located in odd-numbered rows in the first pixel and in even-numbered rows in the second pixel, while a second half of the subpixels having a combination of second colors, the second colors being different from the first colors, are located in even-numbered rows in the first pixel and in odd-numbered rows in the second pixel.

The liquid crystal display panel of the present invention includes a first substrate having an insulating substrate, a thin film transistor, a scan signal line, a first light-shielding electrode, a first insulating film, a second light-shielding electrode, a second insulating film, a transparent electrode, a third insulating film, and a pixel electrode; a second substrate having an insulating substrate; and a liquid crystal layer sandwiched between the first substrate and the second substrate. The second light-shielding electrode is located between the thin film transistor and the pixel electrode and connected to the pixel electrode through a connecting portion formed through the second insulating film and the third insulating film. The first light-shielding electrode at least partly overlaps with the second light-shielding electrode through the first insulating film. The transparent electrode is in a layer closer to the liquid crystal layer than both a layer including the scan signal line and a layer including the second light-shielding electrode are.
