Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a display device having high luminance uniformity and low luminance variation, and its light emitting module.SOLUTION: A display device 10 includes a display panel 200 and a light emitting module 100 opposed to each other. The light emitting module 100 includes a light guide plate 110, a plurality of light guide grooves 111, and at least one optical unit 120. The light guide plate 110 has at least one light incident surface 112, a first surface 113a, and a second surface 113b opposed to the first surface 113a. The light guide grooves 111 are disposed on the first surface 113a. Each light guide groove 111 has a bottom portion as a part closest to the second surface 113b of each light guide groove 111. The longer a distance from the bottom portion to the closest optical unit 120 is, the shorter a distance from the bottom portion to the second surface 113b is.
