Abstract:
1. A liquid crystal display device comprising: a first substrate and a second substrate; a pixel electrode and a passivation layer on the first substrate, the pixel electrode formed on the passivation layer and exposing parts of the passivation layer, the pixel electrode and the parts of the passivation layer being alignment-treated; a common electrode on the second substrate, the common electrode being alignment-treated; and a liquid crystal layer between the first substrate and the second substrate, wherein the common electrode have a surface, which is alignment-treated by irradiating an ion beam using an ion beam irradiation apparatus, wherein the pixel electrode and the parts of the passivation layer have a surface, which are alignment-treated by irradiating the ion beam using the ion beam irradiation apparatus, wherein the liquid crystal layer directly contacts the pixel and the common electrodes on the first and second substrates, wherein the ion beam has an energy of 200-4,000 eV and is irradiated at an angle of 0-90°.
