Title:
LIGHT-GUIDING PLATE COMPRISING AROMATIC POLYCARBONATE RESIN COMPOSITION AND FACE LIGHT SOURCE STRUCTURE
Document Type and Number:
Japanese Patent JP3100853
Kind Code:
B2
Abstract:
PURPOSE: To obtain the subject light-guiding plate for edge light system of a liquid display, comprising a composition obtained by blending an aromatic polycarbonate resin with a specific beads-like crosslinked acrylic resin, having high light transmissivity and excellent light diffusing property.
CONSTITUTION: This composition is obtained by blending (A) 100 pts.wt. aromatic polycarbonate resin with (B) 0.005-0.2 pts.wt. beads-like crosslinked acrylic resin whose weight average particle diameter is 1-30μm. Furthermore, the component B is a resin obtained by subjecting, e.g. an acrylic monomer, specifically methacrylate to suspension polymerization or emulsion polymerization with divinylbenzene, etc., and a resin having preferably 3-20μm weight-average particle diameter and obtained by an electrozone method is preferably used as the component B.
