摘要： Disclosed are a light guide plate and a display device. The light guide plate includes a flat plate portion and a fixed portion, the fixed portion is arranged around a periphery of the flat plate portion, forms an installation groove for placing optical films in cooperation with the flat plate portion, a surface for forming a bottom of the installation groove in the flat plate portion forms a light emergence surface of the light guide plate; gap structures corresponding to light source particles of a light bar are formed at a first side of the fixed portion, and bottoms of the gap structures form a light incidence surface of the light guide plate which is perpendicular to the light emergence surface; and a surface of the flat plate portion back on to the installation groove forms an installation surface for installing a reflection sheet and the light bar.
