The present invention relates to a method of manufacturing a light guide plate with a pattern and the light guide plate manufactured thereby. The method for manufacturing a light guide plate with a pattern comprises the steps of: carving transverse bites spaced apart from each other with a preset distance on a mold for manufacturing the light guide plates; carving longitudinal bites to overlap the positions where the transverse bites are carved so that a cross engraved pattern is formed; and molding the light guide plate with the mold having the cross engraved pattern so that an embossing pattern corresponding to the engraved pattern is formed on the bottom surface of the light guide plate, wherein the transverse and longitudinal bites have a prism shape. According to the present invention, by forming a composite pattern with the transverse and longitudinal patterns in a cross form, on a light guide plate, it is possible to increase luminance through diffusion of light while reducing a loss of light of a backlight device. Thus, the number of optical sheets stacked on the top surface of the light guide plate may be reduced and a wide viewing angle may be achieved. |
