Zusammenfassung:A light guide plate having a prism integrated with a hologram pattern and a manufacturing method thereof are provided to improve luminance of light transmitted from a side of the light guide plate significantly and obtain uniform high luminance by uniformly, upwardly and linearly emitting light emitted from an upper surface of the light guide plate. An upper surface of a light guide plate(93) comprises a periodical pattern. In the periodical pattern, an isosceles triangle inner angle of a quadrangular pyramid is about 50° to 60°, and a square pattern length of the bottom of the quadrangular pyramid is about 0.5 to 50mum. A light guide plate lower surface comprises a non-periodical pattern. In the non-periodical pattern, a square wave protrusion shape is widened at uniform intervals in a center point of the other end side of a light source(91), and a width is about 0.1 to 20mum.
