Abstract
A display device comprises a frame, a light guide plate, optical film groups, a display panel and a shading assembly, wherein the light guide plate, the optical film groups and the display panel are arranged in the frame in sequence, and the shading assembly is arranged between the optical film groups. The shading assembly comprises a sticking portion and a shading portion, wherein the thickness of the sticking portion is larger than that of the shading portion, air layers are formed among the shading portion and the optical film groups, a sticking surface is only formed on the sticking portion, and no sticking surface is formed on the shading portion. Due to the fact that the shading portion where the shading assembly contacts with the optical film groups is free of sticking area, optical films cannot be adhered onto the shading assembly, and therefore, film waving is avoided.
