    • PROBLEM TO BE SOLVED: To prevent breaking of a pixel electrode coating a thin film transistor (TFT), short circuit failure due to a pattern defect and deterioration of leak characteristics due to an etching residue or the like at the time of OFF of the TFT in a case where the TFT and the pixel electrode are formed in the same layer for improving productivity in a liquid crystal display device having a fringe field switching (FFS) mode.SOLUTION: In a display device, side walls made of insulation films are formed on lateral surfaces of a source and drain electrode wiring layer. On account of this, breaking of a pixel electrode, short circuit failure and degradation of leak characteristics at the time of OFF can be prevented. Further, the insulation films are also formed on source wiring. On account of this, capacities of the source wiring and a common electrode can be reduced, and a reduction in capacities thereof contributes to high-speed response properties of display.
    • 要解决的问题:为了防止涂覆薄膜晶体管(TFT)的像素电极的断裂,由于图案缺陷引起的短路故障和由于TFT的OFF时的蚀刻残留物等导致的漏电特性的劣化 在TFT和像素电极形成在同一层中以提高具有条纹场切换(FFS)模式的液晶显示装置的生产率的情况下。在显示装置中,形成由绝缘膜制成的侧壁 在源极和漏极布线层的侧表面上。 由此,可以防止像素电极的断裂,短路故障以及OFF时的泄漏特性的劣化。 此外,绝缘膜也形成在源极布线上。 由此,可以减小源极配线和公共电极的容量,容量的降低有助于显示器的高速响应特性。
