Abstract

A liquid crystal display device includes: a drive circuit; and a plurality of divided display sections which are arranged parallel to each other in a predetermined direction. Each divided display section includes: a plurality of scanning lines which are arranged parallel to each other in the predetermined direction; a plurality of data signal lines, and a plurality of pixel circuits which are provided correspondingly to intersections of the scanning lines and the data signal lines . The drive circuit supplies a signal potential to the data signal line based on a data signal before selecting the scanning line which is included in one or more of the divided display sections, is arranged adjacent to the scanning line included in another divided display section, and is firstly selected and within a blanking period.

Claims (15)

1 . A liquid crystal display device comprising:

a drive circuit; and

a plurality of divided display sections which are arranged parallel to each other in a predetermined direction, wherein each divided display section comprises:

a plurality of scanning lines which are connected to the drive circuit;

a plurality of data signal lines which intersect with the plurality of scanning lines, and are connected to the drive circuit; and

a plurality of pixel circuits which are provided correspondingly to intersections of the scanning lines and the data signal lines, the pixel circuit displaying gray level based on a data signal which is supplied when the corresponding scanning line is selected and is supplied to the corresponding data signal line,

the drive circuit sequentially selects the plurality of scanning lines included in each divided display section from the first scanning line, supplies the data signal to the data signal line included in the divided display section, and repeats the operations from the first scanning line with a lapse of a predetermined period after selecting the last scanning line, and

the drive circuit supplies a signal potential to the data signal line based on the data signal before selecting the first scanning line which is included in at least one of the divided display sections and is arranged adjacent to the scanning line included in another divided display section and within the predetermined period.

2 . The liquid crystal display device according to claim 1 , wherein

the plurality of scanning lines included in each divided display section are arranged in the predetermined direction in order that the scanning lines are selected by the drive circuit, and

the drive circuit supplies the signal potential to the data signal line which is included in one or more of the divided display section based on the data signal which is supplied at the time of selecting at least one of the scanning lines included in another divided display section before selecting the first scanning line which is included in the one or more of the divided display sections and is arranged adjacent to the scanning line included in the another divided display section and within the predetermined period.

3 . The liquid crystal display device according to claim 2 , wherein

the drive circuit supplies the signal potential to the data signal line which is included in one or more of the divided display section based on the data signal which is supplied at the time of selecting the last scanning line which is included in another divided display section before selecting the first scanning line which is included in the one or more of the divided display sections and is arranged adjacent to the scanning line included in the another divided display section and within the predetermined period.

4 . The liquid crystal display device according to claim 1 , wherein

the drive circuit supplies the signal potential to the data signal line which is included in one or more of the divided display section based on the data signal which is supplied at the time of selecting the first scanning line which is included in the one or more of the divided display sections and is arranged adjacent to the scanning line included in another divided display section before selecting the first scanning line and within the predetermined period.
