  • Patent number: 9274381
    Abstract: A fabrication method of a liquid crystal panel is provided. A first substrate and a liquid crystal material are heated to a first fabrication temperature and a one drop filling (ODF) process is performed to drop the heated liquid crystal material on the first substrate, wherein the first fabrication temperature is lower than 70° C. The first substrate is assembled to a second substrate through a sealant under a second fabrication temperature so that the liquid crystal material is sandwiched between the first substrate and the second substrate and located inside a region surrounded by the sealant, wherein the second fabrication temperature is 50° C. to 70° C. Subsequently, the sealant is solidified.

  • Patent number: 9039930
    Abstract: A blue phase liquid crystal display panel and a fabricating method thereof are provided. A first substrate and a second substrate are provided, and then a blue phase liquid crystal composition is filled between the first substrate and the second substrate, wherein the blue phase liquid crystal composition includes a blue phase liquid crystal and a reactive monomer. Next, an irradiation process is performed to induce a polymerization reaction in the reactive monomer of the blue phase liquid crystal composition, wherein a light utilized in the irradiation process has a wavelength ranged from 200 nm to 350 nm.
