  • Patent number: 10048541
    Abstract: A liquid crystal device having higher transmittance and lower driving voltage is provided. The liquid crystal device comprises a first substrate having a first conductive layer, a second substrate having a second conductive layer, a first alignment layer and a liquid crystal layer. The first alignment layer comprises a liquid crystal alignment treatment agent and a methacryloyloxy-containing silane and is disposed on the first conductive layer of the first substrate. The liquid crystal layer comprises a liquid crystal material and a bifunctional-group resin and is disposed on the first alignment layer. The second substrate having a second conductive layer is disposed on the liquid crystal layer.
