Liquid display panel and process for preparing same

摘要

Embodiments of the invention provide a liquid display panel and a process for preparing the same comprising: coating a polymerizable siloxane solution onto either of an array substrate and a color filter substrate; applying a mixture comprising a liquid crystalline polymerizable monomer, a photoinitiator, and liquid crystal between the color filter substrate and the array substrate; and allowing the liquid crystalline polymerizable monomer and the polymerizable siloxane to polymerize under effect of the photoinitiator with UV irradiation to generate a network of high molecular polymers, thereby anchoring liquid crystal molecules in the liquid crystal to a state of vertical orientation. The liquid display panel effectively increases the uniformity of the arrangement of the long axes of the liquid crystal molecules vertical to the array substrate, reduces the deviation of arrangement in the vertical direction among the liquid crystal molecules at different positions of the liquid display panel, and improves display performance of the liquid display panel.
