Liquid crystal display device and manufacturing method thereof
View Patent ↗The present invention provides a liquid crystal display device and a manufacturing method thereof. The liquid crystal display device includes a TFT substrate, a CF substrate opposite to and parallel with the TFT substrate, liquid crystal interposed between the TFT substrate and the CF substrate, spacers arranged between the TFT substrate and the CF substrate, and an enclosing resin frame arranged between the TFT substrate and the CF substrate and located along edges of the TFT substrate and the CF substrate. The TFT substrate and the CF substrate have inside surfaces that oppose the liquid crystal and are both provided with alignment layers. The alignment layers include flexible alignment films, which are in the form of thin membranes and are positioned on the inside surfaces of the TFT substrate and the CF substrate by being stuck thereto.
1. A liquid crystal display device, comprising: a TFT (Thin-Film Transistor) substrate, a CF (Color Filter) substrate that is arranged opposite to and parallel with the TFT substrate, liquid crystal interposed between the TFT substrate and the CF substrate, spacers arranged between the TFT substrate and the CF substrate, and an enclosing resin frame arranged between the TFT substrate and the CF substrate and located along edges of the TFT substrate and the CF substrate, the TFT substrate and the CF substrate having inside surfaces that oppose the liquid crystal and are both provided with alignment layers, the alignment layers comprising flexible alignment films, which are in the form of thin membranes that are separate from the TFT substrate and the CF substrate, each of the flexible alignment films having a first surface opposing the liquid crystal and comprising an alignment structure formed thereon an opposite surface on which adhesive is coated, the flexible alignment films being attachable to the inside surfaces of the TFT substrate and the CF substrate with the adhesive so that the adhesive is sandwiched between the flexible alignment films and the TFT substrate and the CF substrate to fix the flexible alignment films to the inside surfaces of the TFT substrate and the CF substrate.
2. The liquid crystal display device as claimed in claim 1 , wherein the flexible alignment films are formed through stretching, inkjet printing, printing, or polymerization deposition.
3. The liquid crystal display device as claimed in claim 1 , wherein the alignment structures of the flexible alignment films are formed through photoreaction or polymerization deposition.
4. The liquid crystal display device as claimed in claim 3 , wherein the alignment structures have identical direction of alignment.
5. The liquid crystal display device as claimed in claim 3 , wherein the alignment structures are of a fish bone configuration.
