Problems solved by technology

This is mainly due to the fact that the polymerizable unit is too short for the UV sensitive wavelength, or there is no or insufficient tilt angle after illumination, or the uniformity of the polymerizable component is poor after illumination, or because the VHR after UV is not suitable for TFT display applications lower impact

Abstract

The present invention provides a polymer composition of a polymerizable compound represented by formula I, a polymerizable compound represented by formula II, and a polymer compound represented by formula III. The liquid crystal formed by matching the polymerizable composition with a specific liquid crystal component The composition, especially the PSVA liquid crystal composition suitable for display or TV application, and the PSA-IPS liquid crystal composition of IPS mode, especially the polymerizable liquid crystal composition has good solubility, adjustable polymerization speed and post-polymerization morphology, And the "material system" formed by the selected polymerizable component and liquid crystal component has low rotational viscosity, good photoelectric performance, and has a high VHR after (UV) light irradiation, avoiding afterimages in the final display, etc. question.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal composition formed by matching a specific polymerizable liquid crystal composition with a specific liquid crystal component, and a display element or a liquid crystal display containing the liquid crystal composition. Background technique [0002] Thin film transistor liquid crystal display (TFT-LCD) has gone through a long period of basic research. After realizing mass production and commercialization, it has become a mainstream product in LCD applications due to its advantages of lightness, lightness, environmental protection, and high performance: whether it is a small size Mobile phone screens, large-sized notebook computers (Notebook PC) or monitors (Monitor), and large-scale LCD TVs (LCD-TV), TFT-LCD applications can be seen everywhere. [0003] The early commercial TFT-LCD products basically adopted the TN display mode, and the biggest problem was the...
