Liquid crystal display device having an orientation layer containing liquid crystal with a controlled orientation and method for manufacturing the same |
摘要 |
A liquid crystal display having a liquid crystal layer between substrates is provided with a liquid crystal orientation layer sandwiched between a substrate and the liquid crystal layer. The liquid crystal orientation layer is made of a mixture of liquid crystal molecules and a photo polymerizable compound. While projecting an ultraviolet ray so as to harden the photo polymerizable compound, a predetermined voltage set according to a desired pretilt angle is applied, thereby fixing the orientation of the liquid crystal molecules. The liquid crystal molecules of the liquid crystal layer are controlled so as to have an orientation direction set according to the pretilt angle of the liquid crystal orientation layer. The described liquid crystal orientation layer offers easy and accurate control of the pretilt angle. Therefore, for example, in the DAP mode liquid crystal display, a small pretilt angle can be set on an entire surface of the substrate, thereby achieving a high contrast display.
