Abstract

The present invention discloses a heteroatom- and cycloalkyl-containing organic compound and an organic electroluminescent device containing the compound. The general structural formula of the organic compound is as represented by Formula I. The organic compound has a boron-nitrogen structure with multiple resonance effect, wherein a cycloalkyl-containing fluorenyl structure is introduced on the basis of the boron-nitrogen structure. The molecular size is greatly expanded by means of the cycloalkyl group, thereby effectively avoiding a concentration quenching effect, while the molecular orientation is enhanced due to the planarity of the fluorenyl group. In order to further improve the efficiency, a heteroatom is introduced to improve the spin coupling effect, and the oscillator strength is enhanced to improve the energy transfer between a host and a guest; furthermore, by means of the heavy atom effect, the conjugation of a luminous moiety is extended while the efficiency is further improved, avoiding excessive photochromic blue shift, so that the organic compound of the present invention has a good efficiency and lifetime performance. Therefore, an organic electroluminescent device manufactured by using the organic compound of the present invention has a good performance in terms of external quantum efficiency and lifetime.

Abstract

The spontaneous orientation aid for a liquid crystal composition provides storage stability and allows liquid crystal molecules to be vertically aligned without a PI layer when added to a liquid crystal composition. When used in a liquid crystal composition, the spontaneous orientation aid can adsorb to substrates sandwiching a liquid crystal composition (liquid crystal layer) and keep the liquid crystal molecules aligned in a vertical direction. The spontaneous orientation aid makes it possible to align liquid crystal molecules without a PI layer (to induce vertical alignment of liquid crystal molecules under no applied voltage and to achieve horizontal alignment of the liquid crystal molecules under an applied voltage).

Abstract

A compound represented by formula I, a negative liquid crystal composition comprising such a compound, and a liquid crystal display element or liquid crystal display comprising the compound or liquid crystal composition are provided. The compound represented by formula I contains two hydroxy groups. In an ODF process for a panel, due to an intermolecular force between the hydroxyl groups and the surface of the panel (a glass surface or an ITO electrode surface), the compound is spontaneously aligned, in a standing manner, on the panel glass or transparent ITO electrode substrate, causing liquid crystal molecules similar to the compound represented by formula ITO be vertically aligned, and UV light irradiation, a polymer layer with a rough surface is formed on the substrate by means of polymerization, and achieves the effects of PI insulation and vertical alignment of the liquid crystal molecules.

Abstract

A polymerizable composition containing: a) a polymerizable compound having one or two or more polymerizable groups and satisfying formula (I): Re(450 nm)/Re(550 nm)<1.0 (I); b) at least one photopolymerization initiator selected from the group consisting of alkylphenone-based compounds, acylphosphine oxide-based compounds, and oxime ester-based compounds; and c) a polymerization inhibitor. An optically anisotropic body, a retardation film, an antireflective film, and a liquid crystal display device that are produced using the polymerizable liquid crystal composition. The polymerizable composition is excellent in solubility and has high storage stability, so that no precipitation of crystals etc. occurs. When a film-shaped polymer is produced by polymerizing the above composition, the unevenness of the surface of the coating film is small while the alignment of the liquid crystal is maintained, and high durability is obtained. Therefore, the polymerizable composition is useful.

Abstract

The present invention provides a polymerizable composition containing a specific polymerizable compound and a fluorosurfactant having a specific polyoxyalkylene skeleton and having specific molecular weight. The invention also provides an optically anisotropic body, a retardation film, an antireflective film, and a liquid crystal display device that are produced using the polymerizable composition of the present invention. The present invention is useful because, when an optically anisotropic body is produced by photo-polymerization of the polymerizable composition, three features including the leveling properties of the surface of the optically anisotropic body, offset onto the substrate, and liquid crystal alignment can be improved simultaneously.

Abstract

The present invention relates to a liquid crystal display that incorporates a particular liquid crystal composition and a sealant in which a cured form of a particular curable resin composition is used. The present invention provides a liquid crystal display that prevents reduced voltage holding ratio (VHR) and increased ionic density (ID) in the liquid crystal layer and solves the problems of display defects such as voids, alignment irregularities, and image-sticking. Liquid crystal displays according to the present invention, featuring the ability to prevent reduced voltage holding ratio (VHR) in the liquid crystal layer and reduce the occurrence of display defects such as alignment irregularities and image-sticking, are useful particularly to liquid crystal displays in the IPS and FFS modes for active matrix drive and applicable to liquid crystal displays of equipment such as liquid crystal TVs, monitors, mobile phones, and smartphones.
