A method for laser interference lithography using a diffraction grating includes (a) forming a photoresist layer on a work substrate to which a repeated fine pattern is to be formed; (b) forming a refractive index matching material layer on the photoresist layer; (c) forming on the refractive index matching material layer a diffraction grating layer having a period of diffraction grating within the range from &#x3bb;/nto &#x3bb;/n(&#x3bb; is a wavelength of laser beam, nis a refractive index of the diffraction grating, and nis a refractive index in the air or in vacuum); and (d) exposing the photoresist layer by means of mutual interference of positive and negative diffracted lights with the same absolute value by inputting a laser beam perpendicularly to the diffraction grating layer. This method allows to realize an interference pattern with higher resolution and to use a laser source with lower coherence.

An apparatus for driving an electrochromic device (ECD) includes a driving volt age output unit for selectively applying a coloring or decoloring voltage between upper and lower electrodes of an ECD; a timer for counting an applying time of the coloring or decoloring voltage in a memory type driving mode and then outputting a voltage application completion signal after the counted time exceeds a preset time, the timer bypassing the counting operation in a non-memory type driving mode; and a driving controller for selectively inputting a coloring or decoloring signal to the driving voltage output unit such that the driving voltage output unit is controlled to output a coloring or decoloring voltage corresponding to the signal, the driving controller receiving the voltage application completion signal to stop the input of the coloring or decoloring signal. Thus, memory type and non-memory type ECDs may be driven automatically using only one apparatus.

A coating composition for antireflection that includes a low refraction-thermosetting resin having a refractive index of 1.2 to 1.45, a high refraction-ultraviolet curable resin having a refractive index of 1.46 to 2, and an ultraviolet absorber; an antireflection film manufactured using the coating composition; and a method of manufacturing the antireflection film. The antireflection film has excellent abrasion resistance and antireflection characteristic. Further, since the antireflection film can be manufactured in one coating process, it is possible to reduce manufacturing cost.

An LCD (Liquid Crystal Display) device includes a backlight unit, a lower polarizer positioned on the backlight unit, a liquid crystal layer positioned on the lower polarizer, and an upper reflection polarizer positioned on the liquid crystal layer. The upper reflection polarizer is configured such that a regularly arranged metallic line lattice is formed on a support. this LCD device may give a good mirror effect when power is intercepted, and also give a clear display with high brightness even at a bright place when power is supplied to operate the LCD device.
