Abstract:
1. A method for manufacturing a liquid crystal display device, comprising: depositing spacers onto at least one of a first substrate and a second substrate, the spacers being distributed generally randomly along an inner surface of at least one of the first substrate and the second substrate, wherein the first substrate and the second substrate are made of a flexible polymer material, at least a portion of the spacers being coated with at least one of a photoinitiator and an accelerator lacquer initiator; depositing a liquid crystal and pre-polymer mixture onto an inner surface of the first substrate and an inner surface of the second substrate; and laminating together the first substrate and the second substrate to form a liquid crystal cell, wherein if at least a portion of the spacers are coated with the photoinitiator, polymerization is initiated by exposing a first side of the liquid crystal cell and a second side of the liquid crystal cell to ultraviolet light causing scission of the photoinitiator and release of free radicals around the spacers coated with the photoinitiator, and wherein polymerization is automatically initiated by the accelerator lacquer initiators after the liquid crystal and pre-polymer mixture is brought into contact with the accelerator lacquer coated spacers such that polymerization will proceed beginning around each spacer coated with the photoinitiator and/or the accelerator lacquer initiator such that polymer is localized to a region surrounding the spacers and along a direction normal to the first substrate and the second substrate.
