摘要： A TFT substrate (110) of a liquid crystal display device (100) includes a common electrode (112) and a drain electrode (114) facing the common electrode (112) via an insulating layer (113) and provided with an opening (114a) for making an electric field generated between the common electrode (112) and the drain electrode (114) supplied into a liquid crystal layer (130). Since the opening (114a) for making an electric field supplied into the liquid crystal layer (130) is provided in the drain electrode (114) made from metal, the opening (114a) can be formed more finely than before. Thus, a liquid crystal display which can more surely control spray-to-bend transition can be attained.

摘要： A liquid crystal panel development method for a panel including first and second substrates and first and second electrodes with a display voltage applied to liquid crystal interposed therebetween. The method involves applying a voltage signal between the electrodes with an AC voltage component of amplitude Vac and a DC voltage component Vdc, changing Vac and Vdc to measure the range of optimal DC component variation ΔVdc, and determining a structure or material of the liquid crystal panel such that the range of optimal DC component variation ΔVdc becomes less than a given value. ΔVdc=|Vdcb —Vdcw|, where Vdcb is the Vdc value at the minimum range of transmittance variation when Vdc is changed with Vac being fixed for displaying black, and Vdcw is the Vdc value at the minimum range of transmittance variation when Vdc is changed with Vac being fixed for displaying white.
