Title:
LIGHT-DIFFUSING MOLDED BODY, FILM FOR TRANSPARENT SCREEN, AND METHOD FOR EVALUATING LIGHT-DIFFUSING MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2019/208770
Kind Code:
A1
Abstract:
Provided is a light-diffusing molded body, etc., having excellent viewing angle characteristics and excellent color reproduction properties in particular. The above problem is solved by a light-diffusing molded body including a transparent resin binder and light-diffusing particles, wherein, when incident light is radiated to the intersection point of a plane sample of the light-diffusing molded body disposed in a reference position and a perpendicular line which is perpendicular to the plane sample and is along an incidence axis inclined 5° with respect to the perpendicular line, in a relative reflected light intensity distribution of reflected light reflected along a reflected light plane which is a plane which includes the perpendicular line and is perpendicular to the plane sample, and in which a perpendicular plane perpendicular also to a plane including the perpendicular line and the incidence axis is inclined 5° to the opposite side from the incidence axis, the value of the inclination angle between a reference optical axis of regularly reflected light as reflected light proceeding along the line intersection of a reflected light plane and a plane including the perpendicular line and the incidence axis, and the optical axis of reflected light having a relative reflected light intensity of 50% of the intensity of the regularly reflected light, is 18° or greater.
