摘要： At least one embodiment of a liquid crystal display device including a display unit having scan signal lines divided into a plurality of groups which are successively selected. While the scan signal lines belonging to the selected group are successively scanned horizontally, signal potentials of the same polarity are successively supplied to a data signal line. The polarity of the signal potential is reversed between a preceding group and a subsequent group which are selected continuously. A plurality of dummy scan periods are inserted between the horizontal scan period corresponding to the last horizontal scan in the preceding group and the horizontal scan period corresponding to the first horizontal scan in the subsequent group. In each of the dummy scan periods, one of the scan signal lines which belong to the group selected after the preceding group is subjected to a dummy scan so that the scan signal line is maintained in an active state for a predetermined period and then deactivated so as to align the load state of a scan signal line drive circuit. This can reduce irregularities of the horizontal stripes when the data signal line is subjected to the block reverse drive.

摘要： In a liquid crystal display device performing multi-picture element driving, gate OFF timing of a switching element connected between each sub picture element and a signal line is matched with phase timing when all the subsidiary capacity wires are at the same potential. This prevents the occurrence of uneven luminance appearing in a lateral streak.

摘要： In one embodiment of the present invention, a liquid crystal display device is disclosed, each pixel includes first and second subpixels, each of which includes a storage capacitor. Storage capacitor counter voltages applied independently to the storage capacitor counter electrodes of the first and second subpixels are varied within each vertical scanning period of the input video signal. As a result, each vertical scanning period of the input video signal includes a first subframe in which the first and second subpixels have luminances Y_SP1_A and Y_SP2_A, respectively, and a second subframe SFB in which the first and second subpixels have luminances Y_SP1_B and Y_SP2_B, respectively, where Y_SP1_A≠Y_SP2_A, Y_SP1_B≠Y_SP2_B, and Y_SP1_A≠Y_SP1_B or Y_SP2_A≠Y_SP2_B are satisfied. As a result, the viewing angle dependence of the γ characteristic can be reduced with the decrease in the transmittance of the liquid crystal display device minimized.

摘要： Each picture element includes first and second sub-picture elements, each of which includes a liquid crystal capacitor and at least one storage capacitor. After a display voltage representing a certain grayscale level has been applied to the respective sub-picture element electrodes of the first and second sub-picture elements, a voltage difference ΔVα is produced between voltages to be applied to the respective liquid crystal capacitors of the first and second sub-picture elements by way of their associated storage capacitor(s). By setting the voltage difference ΔVα value of the blue and/or cyan picture element(s) to be smaller than that of the other color picture elements, shift toward the yellow range at an oblique viewing angle can be minimized.
