<p>A light guide plate and a planar light-emission apparatus having the light guide plate, a liquid crystal display apparatus, a liquid crystal display terminal device, and a method for manufacturing a light guide plate. A scattering pattern on a bottom surface (3) of the light guide plate has a colorless transparent adhesive pattern layer (7) provided on a plane of a substrate (1), multiple miniature scattering particles (8) are planted and bonded on the adhesive pattern layer (7) to obtain a three-dimensional microstructured scattering pattern layer (6), all or a part of the planted and bonded miniature scattering particles (8) protrude from a surface of the adhesive pattern layer (7), a part of the miniature scattering particles (8) exposed and protruding from the surface of the adhesive pattern layer (7) are inserted in the colorless transparent adhesive pattern layer (7) to be securely bonded by using an adhesive, the rest part of the miniature scattering particles (8) are exposed and protrude from the colorless transparent adhesive pattern layer (7). A planar light-emission apparatus in which such a light guide plate is used has an increase rate of brightness exceeding 20%. By means of the manufacturing method, light guide plates in large, medium, and small sizes can be manufactured with high quality, thereby fully achieving an increase of brightness for a light guide plate.</p> |
