Scanning signal line drive circuit and display device equipped with same

摘要

Provided is a monolithic gate driver capable of performing block-reversal driving without causing deterioration of display quality or an increase in power consumption. Gate bus lines are divided into z blocks. Agate driver (400) is provided with a block scanning circuit (40), as well as odd-numbered line scanning circuits (42) each provided for each block and even-numbered line scanning circuits (44) each provided for each block. The block scanning circuit (40) sequentially selects the first to z-th blocks one by one, and alternately selects the odd-numbered line scanning circuits (42) and the even-numbered line scanning circuits (44). Each of the odd-numbered line scanning circuits (42) sequentially and selectively drives the odd-numbered gate bus lines included in the corresponding block. Each of the even-numbered line scanning circuits (44) sequentially and selectively drives the even-numbered gate bus lines included in the corresponding block.
