Abstract: A display device includes a display panel and a backlight module. The backlight module includes a light-emitting unit and a light guiding unit. The light guiding unit has a light input surface. The light-emitting unit has a plurality of light-emitting elements, which are disposed along a first direction and adjacent to the light input surface. A second direction is from the light input surface to the light-emitting unit. The light guiding unit includes a first protruding portion, which includes a part of the light input surface. The light input surface includes a connecting surface, which connects to the first protruding portion to form a turning portion. The turning portion is disposed between the connecting surface and the first protruding portion. The connecting surface is a planar or curved surface protruding along the second direction. The first protruding portion protrudes along the second direction and extends along the first direction.
