Abstract:
1. A method of fabricating a liquid crystal display (LCD) device, the method comprising: providing a first substrate including a plurality of pixels defined by a plurality of gate lines and data lines and thin film transistors (TFTs) arranged at each of the pixels; forming a first alignment layer on the first substrate; alignment-processing the first alignment layer; providing a second substrate having a color filter layer and a black matrix thereon; forming a second alignment layer on the second substrate; alignment-processing the second alignment layer; and attaching the first and second substrates to each other, wherein at least one of the first and second alignment layers is formed of an alignment material including reactive mesogens and a photoinitiator, the reactive mesogens having a mesogen, flexible spacers at ends of the mesogen, and photo-reactive end groups at ends of the flexible spacers, and at least one of the first and second alignment layers is aligned by irradiating UV light in a state that an electric field has been applied to the alignment layer in a predetermined direction, wherein the electric field is applied to the first substrate by applying a voltage between an odd numbered gate line and an even numbered gate line formed on the first substrate to generate an electric field between the odd numbered gate line and the even numbered gate line caused by a voltage difference, thereby the reactive mesogens and the photoinitiator are polymerized to form a polymer network in vertical direction of the electric field.
