液晶面板及其所使用之主动矩阵基板;LIQUID CRYSTAL PANEL AND ACTIVE MATRIX SUBSTRATE USED THEREFOR

摘要

液晶面板(100)包括：一对基板(10、30)；液晶层(40)，其被保持于一对基板之间；及密封材料(42)，其以包围液晶层之方式而设；于被密封材料包围之区域矩阵状形成有复数个像素(P1、P2)；上述复数个像素各者具有：氧化物半导体TFT(5)，其设置于一基板(10)；及像素电极(19)，其设置于一基板且连接于氧化物半导体TFT；且该液晶面板(100)构成为于氧化物半导体TFT自导通状态切换为断开状态时，利用像素电极施加至液晶层之电压仅朝负方向位准偏移相当于引入电压△Vd的程度；复数个像素中之第1像素(P1)之引入电压△Vd1小于相对于密封材料较第1像素位于更远处之第2像素(P2)之引入电压△Vd2。 A liquid crystal panel (100) includes a pair of substrates (10,30), a liquid crystal layer (40) retained between the pair of substrates, and a sealant (42) surrounding the liquid crystal layer. A plurality of pixels (P1,P2) are formed in a matrix shape in a region surrounded by the sealant, each of the plurality of pixels having an oxide semiconductor TFT (5) provided on one of the substrates (10) and a pixel electrode (19) provided on the one substrate and connected to the oxide semiconductor TFT. When the oxide semiconductor TFT switches from an ON state to an OFF state, a voltage which is applied to the liquid crystal layer via the pixel electrode undergoes a level shift by a feed-through voltage △ Vd in the minus direction. Among the plurality of pixels, a feed-through voltage △ Vd1 of a first pixel (P1) is smaller than a feed-through voltage △
