The invention relates to compensation films for liquid-crystal displays with additions of rod-shaped liquid crystals mentioned below, to polarizer plates which have at least one compensation film of this type, to liquid-crystal displays which have compensation films of the said type, and to processes for the production of the said compensation films, polarizer plates and liquid-crystal displays, to the use of the compounds described in greater detail below as additions to compensation films for liquid-crystal displays, and to further subject-matters of the invention which can be seen below.

Optical compensation films

Disclosed are novel liquid-crystal compounds, processes and intermediates for the preparation thereof, the use thereof for optical, electro-optical and electronic purposes, in particular in liquid-crystal (LC) media and LC displays, and to LC media and LC displays containing the same.

Liquid-crystal compounds and LC media

The present invention relates to OLEDs which have at least one substrate, a 1st electrode, at least one organic light-emitting layer and a 2nd electrode, where either the substrate and the 1st electrode, the 2nd electrode or the substrate and the 1st and 2nd electrodes are transparent, which are characterised in that at least one transparent layer which contains transparent, preferably spherical particles, which protrude at least partially out of the at least one layer is arranged on the substrate and/or the transparent 2nd electrode, to processes for the production thereof, and to the use thereof, in particular in illumination devices and displays.

OLEDs with increased light yield

The present invention relates to polyimide photo alignment films for liquid crystal display devices comprising an aromatic tetracarboxylic dianhydride component containing 3,3&prime;,4,4&prime;-benzophenone tetracarboxylic dianhydride and an aromatic diamine component containing at least one diamine of the group of fofmulae AI to AIII as given in the text. Further display devices and methods of their fabrication employing a photo alignment process are disclosed.

Polymide photo alignment film from 3,3&prime;,4,4&prime;-benzophenone tetracarboxylic dianhydride and ortho-substituted aromatic diamines for liquid crystal displays

The present invention relates to polyimide photo alignment films for liquid crystal display devices comprising an aromatic tetracarboxylic dianhydride component containing 3,3',4,4'-benzophenone tetracarboxylic dianhydride and an aromatic diamine component containing at least one diamine of the group of formulae AI to AIII as given in the text. Further display devices and methods of their fabrication employing a photo alignment process are disclosed.

Polyimide photo alignment film from 3,3,4,4-benzophenone tetracarboxylic

A polyimide alignment film based on 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride and ortho-substituted aromatic diamines, such as 2,3,5,6-tetramethyl-p-phenylene diamine, 2,4,6-trimethyl-m-phenylene diamine and 1,5-diaminonaphthalene, providing high voltage holding ratio and high tilt angle when used in active matrix liquid crystal displays.
