Abstract: The present invention relates to a surface light source device and a backlight unit including the same and, more particularly, to the surface light source device and the backlight unit including the same, capable of slimming a module and reducing manufacturing costs by reducing the number of optical components and obtaining high and uniform brightness properties by optimizing front brightness rise efficiency through the angle control of a prism. For this, the surface light source device includes a light guide plate which includes an incident surface to which light is inputted from a light source which is arranged along a preset axis, an output surface which outputs the incident light, and a rear surface which faces the output surface; and a micro prism sheet. A lenticular pattern is formed on the output surface. A plurality of unit cells with micro prism patterns are dispersed on the rear surface. A vertical angel (θ) of the unit prism of the micro prism pattern is 80° to 83°. The arrangement direction of the unit prism is parallel to the arrangement direction of the light source. The micro prism sheet is laminated on the light guide plate. The vertical angle (θ) of the prism is 90° to 110° on the micro prism sheet.
