    • A liquid crystal display device (1) includes: a plurality of groups of scanning lines (Gia) and (Gib) via which gate signals are outputted to a plurality of pixels (PIX); and scanning line driving circuits (5a) and (5b) which generate the gate signals and which are disposed for each separate one of a plurality of groups of scanning lines (Gia) and (Gib), the liquid crystal display device (1) further including potential control circuits (15a) and (15b), placed in front of the scanning line driving circuits (5a) and (5b), respectively which incline, for each separate one of the groups of scanning lines (Gia) and (Gib), falling edges of high-potential signals (VGH1) and (VGH2) in accordance with which the gate signals are generated and which are composed of pulse waves. This prevents luminance unevenness from occurring in each display region.
    • 液晶显示装置(1)包括:多个扫描线组(Gia)和(Gib)组,通过该组扫描线将栅极信号输出到多个像素(PIX); 和扫描线驱动电路(5a)和(5b),所述扫描线驱动电路(5a)和(5b)产生所述栅极信号,并且被设置用于多组扫描线(Gia)和(Gib)中的每一个分离的所述液晶显示装置(1) 包括对于扫描线组(Gia)和(Gib)中的每一个分别放置在扫描线驱动电路(5a)和(5b)的前面的电位控制电路(15a)和(15b) ,根据其生成栅极信号并由脉冲波组成的高电位信号(VGH1)和(VGH2)的下降沿。 这防止了在每个显示区域中发生亮度不均匀。
