This invention relates to backlight device with angle adjustment, which includes a light source module, an optical member and a light guiding plate, wherein the optical member is equipped on one side of the light source and has a light-receiving surface and a light-leaving surface. The light source generates a plurality of first light rays to the optical member, and the light-receiving surface receives the plurality of first light rays according to a plurality of first optical paths synchronously. The optical member generates a plurality of second optical paths according to those first optical paths. The light-leaving surface, corresponding to the second optical paths, outputs a plurality of second light rays to the light guiding plate. Moreover, this invention can provide a multi-angle light source projected onto the light guiding plate by arranging a plurality of light sources in curved configuration on XY plane. Therefore, the backlight device of this invention can provide a backlight source of multiple vi
