Abstract
A signal circuit of the present invention includes (i) a plurality of signal sources; (ii) a plurality of source lines; and driving means for driving the data lines, the source lines being divided into a plurality of groups, each of the groups including three source lines, adjacent groups constituting one block, wherein: the driving means selects groups which belong to a clump of blocks including a first block, and a second block adjacent to the first block so that, (i) during a first predetermined period, the driving means simultaneously selects groups that belong to the first block, and simultaneously selects groups that belong to the second block, and (ii) during a second predetermined period subsequent to the first predetermined period, the driving means selects groups one by one from groups disposed at respective ends of the clump of blocks, simultaneously selects adjacent groups that belong to different blocks, and selects remaining groups one by one. With this arrangement, it becomes difficult for display unevenness having a vertical-striped shape to be noticeable due to the change in electric potential.
