Abstract

The present invention relates to a light control film, comprising:

• • two transparent electroconductive resin substrates; and
  • a light control layer sandwiched by the two transparent electroconductive resin substrates,
  • wherein the light control layer contains a resin matrix and a light control suspension dispersed in the resin matrix, and the thickness of the transparent electroconductive resin substrates is from 130 to 500 μm.

Claims

1. A light control film, comprising:

two transparent electroconductive resin substrates; and

a light control layer sandwiched by the two transparent electroconductive resin substrates,

wherein the light control layer contains a resin matrix and a light control suspension dispersed in the resin matrix, and the thickness of the transparent electroconductive resin substrates is from 130 to 500 μ

m.

3. The light control film according to claim 1, wherein the thicknesses of the two transparent electroconductive resin substrates are equal to each other.

4. The light control film according to claim 1, wherein the thickness of the light control layer is from 10 to 200 μ
