Liquid crystal display device with alignment layer formed of a mixture of a rubbing alignment material and a UV alignment material
Abstract:
An LCD device includes first and second substrates, an alignment layer formed over at least one of the substrates, and a liquid crystal layer formed between the substrates. The alignment layer is formed of a mixture of rubbing alignment and UV alignment materials. A method of fabricating the LCD device includes preparing first and second substrates; coating an alignment layer over at least one of the substrates; performing a rubbing process on the substrate coated with the alignment layer; and irradiating polarized UV rays onto the substrate coated with the alignment layer, wherein the alignment layer is formed of a mixture of rubbing alignment a UV alignment materials. The rubbing process obtains high anchoring energy is obtained, thereby preventing afterimages. Also, the process of irradiating the polarized UV rays eliminates the problem of light leakage.
