Patent ID: 7569257

Claim:
A light modulating plate, comprising: a light modulating layer, including a foam layer; and a light characteristics improving member integrally formed with the light modulating layer, wherein the light modulating layer comprises: a first foam layer having a plurality of first air bubbles to scatter an externally provided light; a diffusion layer formed on the first foam layer to diffuse the scattered light, the diffusion layer being substantially free of air bubbles; a second foam layer formed on the diffusion layer and having a plurality of second air bubbles, the second foam layer scattering the diffused light; and an adhesive layer formed between the light modulating layer and the light characteristics improving member to integrally combine the light modulating layer and the light characteristics improving member, the adhesive layer including an adhesive agent and air bubbles in the adhesive agent scattering the light scattered by the second foam layer, the air bubbles of the adhesive layer having a diameter smaller than that of the plurality of first air bubbles or the plurality of second air bubbles.
