  The present invention relates to a liquid crystal display device that includes a particular color filter containing a material containing chiral liquid crystals and a particular dye and/or pigment. The present invention provides a liquid crystal display device that can prevent a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and solve the problem of display defects, such as white spots, variations in alignment, and burn-in. Because liquid crystal display devices according to the present invention characteristically prevent a decrease in the voltage holding ratio (VHR) of a liquid crystal layer and reduces the occurrence of display defects, such as burn-in, the liquid crystal display devices are particularly useful as liquid crystal display devices in IPS mode and FFS mode for active-matrix driving and can be applied to household electrical appliances, automobiles, production facilities, measuring and analytical instruments, and communication devices.

  本发明涉及一种液晶显示装置，其中包括一种特定的彩色滤光片，该滤光片含有手性液晶和特定染料和/或颜料的材料。 本发明提供的液晶显示装置可防止液晶层的电压保持率（VHR）下降，并解决显示缺陷问题，如白斑、排列变化和烧损。 由于根据本发明的液晶显示装置具有防止液晶层的电压保持比（VHR）降低和减少显示缺陷（如烧毁）发生的特点，因此该液晶显示装置特别适用于有源矩阵驱动的 IPS 模式和 FFS 模式的液晶显示装置，并可应用于家用电器、汽车、生产设备、测量和分析仪器以及通信设备。

  The present invention provides a method for producing a liquid crystal composition which mixes two or more liquid crystal compounds, namely, a method for producing a liquid crystal composition, including conducting agitation or ultrasonic irradiation of two or more liquid crystal compounds without applying external heat, wherein at least one of the liquid crystal compounds has a melting point higher than 40° C., and a temperature at a start of the agitation or ultrasonic irradiation is not more than 40° C. The production method of the present invention enables a highly reliable, high-quality liquid crystal composition to be produced without the necessity for large-scale equipment such as a pressure reduction apparatus or heating apparatus. Accordingly, this method is extremely practical for the production of liquid crystal compositions that require a high level of reliability.
