Patent ID: 8865274

Claim:
A liquid crystal display device comprising: a liquid crystal layer comprising liquid crystal molecules interposed between a first display panel and a second display panel; and an alignment film formed on at least one of the first display panel and the second display panels, the alignment film comprising: a first polysiloxane of a first layer; a second polysiloxane of a second layer disposed on the first layer; wherein a first portion of silicon atoms of the second polysiloxane is bonded to a vertical functional group interacting with the liquid crystal molecules in the liquid crystal layer; wherein a second portion of silicon atoms of the second polysiloxane is bonded to a first pre-tilting functional group to cause the liquid crystal molecules in the liquid crystal layer to be tilted with respect to at least one of the first and second display panels; wherein a third portion of the silicon atoms of the second polysiloxane is bonded to a second pre-tilting functional group cross-linked to the first pre-tilting functional group; wherein the first polysiloxane and the second polysiloxane have different bonding structures; and wherein the first polysiloxane is bonded to a phase separation enhancer.
