Horizontal-switching flexible liquid crystal displays (LCD) and fabrication methods thereof are provided. The horizontal-switching flexible liquid crystal display includes a flexible first substrate, a second substrate and a liquid crystal (LC) layer interposed therebetween. The LC layer consists of liquid crystal molecules affected by a horizontal field and divided into an upper portion and a lower portion. At least one pair of a patterned pixel electrode and a common electrode is disposed on the first substrate. The pixel electrode and the common electrode are formed on the same plane, thereby generating a horizontal field during operation. First and second alignment layers allow the LC molecules of the LC layer to be in a substantially vertical alignment. The phase retardation of the horizontal-switching LCD is due to the lower portion of the LC layer.

The present invention discloses a method for manufacturing liquid crystal display (LCD) device by utilizing photopolymer. A first photopolymer layer is coated on the support substrate and the substrate having a buffer layer is treated by photopolymerization. A substrate is treated by processes for forming an electrode layer, an alignment layer and projections as required by general LCD manufacturing. A second photopolymer layer is coated on the substrate having a plurality electrode patterns, an alignment layer and projections. Mask exposure is applied to the substrate and the photopolymer forms a polymer wall. Alternatively molding can be applied to the substrate along with linear ultra violet exposure. The photopolymer layer is hardened by such process and forms a polymer wall with alignment. The cavities in the polymer wall are filled with mixture of liquid crystal and small amount of photopolymer. The support substrate and the substrate are aligned and treated by mask exposure for coupling the support substrate to the substrate via photopolymerization. The support substrate is separated from the substrate and accordingly a single substrate LCD device is generated. The same method can be applied to manufacturing process for a LCD device without a substrate. The method increases yield rate also provides a different method for manufacturing a LCD device.
