摘要:
A light guide plate which can achieve improvement of back-lighting or front-lighting luminance without increase of luminance of a light source, and a liquid crystal display device using such a light guide plate. A large number of concave small dots are formed in a surface of the light guide plate opposite to a light emitting surface of the light guide plate which emits light to a liquid crystal cell array so that light incident on the light guide plate from the light source is reflected at the concave small dots in the direction toward the light emitting surface of the light guide plate. Each of the concave small dots is shaped like a triangle with a sectional inclination angle of from 50 to 60° in sectional view and shaped like an approximate rectangle or square in plan view in the direction perpendicular to a surface of the light guide plate and disposed so that a long side of the approximate rectangle or a side of the approximate square is approximately parallel with the longitudinal direction of the light source.

A method for manufacturing an edible soy protein containing, simulated meat product containing a fibrous soy protein product of fibril structure having a random orientation, and non-textured protein material. A mixture of 90 to 50 % by weight of non-textured protein material i.e. a proteinaceous paste and 10 to 50 % by weight of the fibrous soy protein product is shaped and heat-treated, by which method, a small amount of the latter forms a supporting structure in the large amount of the former, thus producing simulated meat products having qualities which are comparable to high grade natural meats.
