<p><P>PROBLEM TO BE SOLVED: To provide a light guide plate for emitting light in which the degree of yellow is sufficiently controlled while it contains particulates for scattering light. <P>SOLUTION: The light guide plate 3 includes particulates scattered in a transparent resin, and when the absolute value of the difference between the refractive index of the transparent resin and the refractive index of the particulates is made [Δn], and the accumulated 50% particle diameter of the particulates is made [D<SB>50</SB>] (μm), a relation formula of 0.30≤Δn×D<SB>50</SB>≤0.70 is satisfied, and the average light transmittance of visible light as measured by optical path length of 300 mm is 35% or more. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
