  • Publication number: 20150168750
    Abstract: The present invention proposes a liquid crystal alignment device and the liquid crystal alignment device comprises light sources, a light emitting plate and reflective plates, and the light sources are disposed on the light emitting plate; the reflective plate is disposed on a side surface of the light sources, and a reflective surface of each of the reflective plates is facing the light sources; the reflective surface of the reflective plate appears to be a rough shape. Therefore, even if the UV rays emitted by the light source are not uniform, the evenness of the UV rays transmitted to the liquid crystal layer can be ensured after the reflection of the reflective plate, and thereby avoid the Mura occurring during the alignment process. The product yield is increased and the display result of the LCD is guaranteed.
