Abstract
A curved backlight module includes a frame unit, a light source, and a diffuser plate. The frame unit includes a back frame, a curvature fixing member combined with the back frame, and at least one first positioning structure. The at least one first positioning structure is disposed on anyone of the back frame or the curvature fixing member. The curvature fixing member presses the diffuser plate so that at least a portion of the diffuser plate has the same curvature with the curvature fixing member. The diffuser plate has at least one second positioning structure, the at least one first positioning structure of the frame unit is combined with the at least one second positioning structure of the diffuser plate to limit the diffuser plate and simplify the structure of the positioning elements. The curvature fixing member stably maintains the curvature of the diffuser plate, thereby improving the overall structural stability and optical quality. The present invention further provides a display device including the curved backlight module.
