摘要：
An edge-light type light guide plate (30) is provided that has a first surface (31) and a second surface (32) that are opposed to each other, and a peripheral edge surface extending between the peripheral edges of the first and second surfaces. A part of the peripheral edge surface is defined as a light entrance plane (30a). The first surface (31) has a series of parallel elongated raised surfaces (31a) of arcuate cross-section that extend in a direction substantially normal to the light entrance plane (30a). The second surface (32) has a series of parallel elongated recessed surfaces (32a) of triangular cross-section that extend in a direction substantially normal to the elongated raised surfaces (31a) on the first surface.
