Abstract:
1. A light diffusing laminated plate, comprising: a first light diffusing layer of a light transmissive resin containing particles of a transparent light diffusing material dispersed therein, said first light diffusing layer having a substantially uniform cross-section in one direction and a first surface concave in said cross-section; and a second light diffusing layer of a light transmissive resin containing particles of an opaque light diffusing material dispersed therein, said second light diffusing layer having a substantially uniform cross-section in one direction and a first surface convex in said cross-section and coinciding with said first surface of said first light diffusing layer, wherein said first and second light diffusing layers are laminated together such that said first surface of said first light diffusing layer is in face to face contact with said first surface of said second light diffusing layer to form a curved interface therebetween.
