摘要： In a liquid crystal panel in which pseudo dot inversion driving is performed, the occurrence of flicker or vertical and horizontal strings is prevented by preventing an alignment shift between individual layers during the fabrication of a TFT array from producing a difference between the respective abilities of thin-film TFTs to charge adjacent pixels (61, 62). For this purpose, the liquid crystal display panel is constructed such that two TFTs which are enclosed by two adjacent image signal lines (21, 22) and scan signal lines (3) and adjacent to each other along the signal lines (21, 22) have respective source electrodes (71, 72) adjacent to the different image signal lines (21, 22). The source electrodes (71, 72) and drain electrodes (81, 82) of the two TFTs connected to the adjacent pixels (61, 62) are alternately arranged such that variations caused by the alignment shift in the sizes and areas of overlapping portions between the individual layers of the TFTs are equal or the same.

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.
