Abstract

A methacrylic resin extrusion plate for use in a light guide plate is provided. The methacrylic resin extrusion plate is formed by a mixture having an apparent density of 0.80 g/ml or above prepared by mixing methacrylic resin polymer of a definite shape having an apparent density of 0.63 g/ml to 0.78 g/ml and methacrylic resin polymer of an indefinite shape having an apparent density of 0.55 g/ml to 0.63 g/ml. The plate thickness accuracy in the width direction is controlled to be within ± 1.0% of the average plate thickness. The methacrylic resin extrusion plate for a light guide plate is preferably used for office automation devices such as a personal computer and a word processor, display devices used for various monitors displaying an image signal such as a panel monitor and a television monitor, display devices used for indoor or outdoor illumination devices and sign boards.
