Abstract
A driving circuit according to an embodiment of the invention includes: a switching unit for sequentially switching between a first operation of applying a positive gray-scale voltage to odd-numbered data lines and applying a negative gray-scale voltage to even-numbered data lines and a second operation of applying a negative gray-scale voltage to odd-numbered data lines and applying a positive gray-scale voltage to the even-numbered data lines; a plurality of short-circuit switches for short-circuiting a pair of adjacent odd-numbered data lines and a pair of adjacent even-numbered data lines to produce a plurality of pairs of short-circuited data lines in a switching period between the first operation and the second operation; and a plurality of common node-connected switches corresponding to the plurality of data line pairs and short-circuiting a corresponding one of the data line pairs to a common node.
