PRETILT ANGLES OF LIQUID CRYSTAL ON ORGANIC-SOLVENT-SOLUBLE POLYIMIDE ALIGNMENT FILMS

The increase of pretilt angle of liquid crystal in an active matrix (AM) liquid crystal display (LCD) is one of the most important issues to achieve high-contrast and defect-free AM LCDs. We have developed a new generation method of the pretilt angle by using newly synthesized organic-solvent-soluble polyimides containing two types of diamine. The maximum pretilt angle of 2.8° for a nematic liquid crystal is obtained using new polyimides.
