Liquid crystal display device having improved alignment of liquid crystals

Abstract

A liquid crystal display device provides for improved alignment of its liquid crystal molecules by having an alignment layer with polymer branches that are cured so as to reinforce a predefined orientation of the liquid crystal molecules even when no voltages are applied to the pixel-electrodes and/or common electrode of the device. Bruising of the screen can thus be rapidly repaired. In one embodiment, the device includes: first and second substrates opposed to each other; a liquid crystal layer including liquid crystal molecules interposed between the substrates; a gate line formed on the first substrate; first and second data lines formed on the first substrate and connected for transmitting first and second data voltages having different polarities; a first and second switching elements respectively connected to the gate line and the first or second data line; first and second pixel electrodes that are connected to the first and second switching elements, respectively; an alignment layer formed on the first and second pixel electrodes; and a polymer layer including a plurality of cured prepolymers that are cured so as to prearrange the liquid crystal molecules in a desired orientation.
