Title:
LIQUID CRYSTAL DISPLAY ELEMENT AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2014/123056
Kind Code:
A1
Abstract:
Provided is a liquid crystal display element and a manufacturing method for the same by which the occurrence of burn-in and of drip marks during manufacturing is mitigated without worsening various characteristics such as dielectric anisotropy, viscosity, nematic phase upper-limit temperature, and rotational viscosity (γ1). The liquid crystal display element is characterized in that a liquid crystal layer containing a liquid crystal composition is sandwiched between a substrate having a common electrode and a color filter, and a substrate having a plurality of pixels, each of the pixels having a pixel electrode. The liquid crystal display element is further characterized in that the substrates do not have alignment films but have alignment control layers made of two or more polymerizable compounds, the pixels have two or more regions with different pretilt directions, and the liquid crystal composition contains compounds expressed by General Formula (I) and General Formula (II).
