A light guide plate has a light exiting side, a reflection side opposite to the light exiting side, and a light entering side. A plurality of miniature diffusing entities, each having a curved surface and two slant surfaces extending from the two ends of the curved surface, are formed on the light entering side. The combination of the curved surface and the two slant surfaces cause light emitted from point-like light sources to have wider incident angles and be uniformly scattered into the light guide plate.

A light-conductive board and a rear light module using the light-conductive board is disclosed. The light-conductive plate having a light-emitting face, a light-reflecting face, and at least a light-entering face and the light-reflecting plate adhered onto the external of the light-reflecting face of the light-conductive board, an optical film including a divergent lens and a convergent lens mounted onto the external of light-emitting face of the light-conductive board, a lamp reflector which encloses a lamp source, and the light-entering face of the light-conductive board corresponding to the circumferential edge of the light-entering recessed region of the lamp source adjacent to the light-emitting face or one of the face of the reflection face at least forms into a protruded section.
