ABSTRACT:
A method for the formation of orientation film of a liquid crystal display.
The method comprises the steps of forming polyvinyl-4-fluorocinnamate (hereinafter "PVCN-F") film on the surfaces of two opposite substrates and irradiating the two PVCN-F films formed with linearly polarized UV lights having different energy.
The method in accordance with the present invention is capable of not only providing the pretilt angle to a fabricated LCD but also adjusting it by illuminating two substrates with linearly polarized UV beams having different energies from each other, respectively. In addition, the LCD fabricated by the method according to the present invention requires a much lower driving voltage, as compared with the conventional LCD having an orientation film of planar structure. Furthermore, phase distortion and light scattering phenomena do not occur in the LCD, so that display characteristics such as contrast and the like can be improved.
The orientation film is formed of polyvinyl-4-fluorocinnamate which is highly resistant to heat, so that the LCD according to the present invention has an excellent thermostability.
