Title:
LIGHT TRANSMISSION ADJUSTING DEVICE AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2008064992
Kind Code:
A
Abstract:

To provide a light transmission adjusting device capable of arraying electric-field array particles with a low transmission response voltage, and a display device having the light transmission adjusting device.

The light transmission adjusting device 2 according to the present invention has a pair of opposed transparent electrode plates 4A and 4B, capsules 6 disposed between the pair of transparent electrode plates 4A and 4B, and light-transmissive inter-electrode resin 8 charged into the gap between the capsules between the pair of transparent electrode plates 4A and 4B. The capsules 6 have electric-field array particles 16 having electric-field array effect, a nonpolar solvent 18 having light transmissivity, and a light-transmissive film including the electric-field array particles 16 and nonpolar solvent 18. The inter-electrode resin 8 has a larger relative dielectric constant than the nonpolar solvent 18.
