<p>PURPOSE:To simplify and facilitate the adjustment of white balance by changing the permeability of green damping filter as well as the application voltage applied to an electrode for display. CONSTITUTION:A green damping filter 40 is provided on the display surface side of a color filter 18, and by chaging the permeability of the filter 40 as well as the application voltage applied to an electrode 10 for display, white balance adjustment is carried out. Namely, by changing the permeability of the filter 40, the component of green light can be adjusted, while by changing the application voltage applied to the electrode 10, the component of red and blue lights can be adjusted. For example, by increasing the application voltage, the percentage of the blue color is reduced, while the percentage of the red color can be increased. By chaning the permeability of the filter 40 and the application voltage applied to the electrode 10, white balance can be adjusted. The white balance adjustment of the display device can thus be easily carried out.</p> |
