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.
