摘要： A thin flat-surface type display device having a transmissive display panel is provided, which is capable of securing a space of an essential electric circuit for driving the display device without deteriorating an optical performance (luminance and uniformity thereof) of a surface light source device of an edge light system employed as a backlight. A light guide plate forming the surface light source device of the edge light system has a flat light emitting surface, and a back surface arranged so as to include (1) an inclined flat surface portion where a thickness of the light guide plate decreases linearly from a light-incident portion on which light emitted from a linear light source is incident toward a light-anti-incident portion, and (2) a parallel flat surface portion which is parallel with the light emitting surface in the vicinity of the light-anti-incident portion. Also, the two adjacent surfaces are connected to each other at an interface portion with an interface curved surface such that makes the two adjacent surfaces tangential. In addition, reflection dots are formed at the back surface side of the light guide plate in a predetermined shape at a predetermined density.
