Abstract
A display device, such as an LCD, has alignment layers made of different materials; thus one layer can have a low curing temperature so as not to cause damage to delicate organic layers, such as a color filter, during curing, while the other layer can have a larger tilt angle so as to minimize ambiguities in the liquid crystal material.
