Patent ID: 7746313

Claim:
A display device comprising: a display section including a plurality of sub-pixels and a plurality of video lines which supply gray scale voltages to said plurality of sub-pixels, said plurality of video lines being divided into a plurality of blocks each comprised of m video lines of said plurality of video lines, m being an integer equal to or greater than 2; a video line drive circuit which outputs m gray scale voltages corresponding to m video lines of each of said plurality of blocks time-sequentially; and a plurality of switch groups each comprised of first to mth switches, each of said plurality of switch groups corresponding to one of said plurality of blocks of video lines, receiving said m gray scale voltages from said video line drive circuit, and then supplying said m gray scale voltages to said m video lines of said one of said plurality of blocks in a time-division multiplexed fashion, wherein: said mth switch is turned on last during a writing time T during which said m gray scale voltages are written into corresponding ones of said plurality of sub-pixels, and the following inequality is satisfied: Tq<Tm, where Tm is a time during which said mth switch is turned on, Tq is a time during which a qth switch of said first to (m−1)th switches is turned on, and q is an integer of from 1 to (m−1), and said first to mth switches are first to mth switching elements comprised of transistors, respectively, and the following inequality is satisfied: | VGr|>|VGm|, where |VGr| is an absolute value of a voltage difference between a control voltage applied on an rth switching element of said first to (m−1)th switching elements for turning off said rth switching element and a control voltage applied on said rth switching element for turning on said rth switching element, r being an integer of from 1 to (m−1), and |VGm| is an absolute value of a voltage difference between a control voltage applied on said mth switching element for turning off said mth switching element and a control voltage applied on said mth switching element for turning on said mth switching element.
