Abstract
An apparatus for driving source lines includes an output buffer, a first switch and a second switch. The output buffer outputs a first voltage and a second voltage having an opposite phase to the first voltage during an output interval including a first interval portion and a second interval portion. The first switch applies the first and second voltages to an m-th source line and an (m+1)-th source line respectively during the first interval portion and blocks the first and second voltages during the second interval portion. The second switch includes a plurality of switching elements, the second switch short-circuiting the m-th source line and the (m+1)-th source line during the second interval portion, wherein the m-th source line has at least two connecting portions to be electrically connected to the (m+1)-th source line.
