The display device is provided with: a display panel that displays an image; a circuit board 20 that is disposed on a back surface of the display panel; a plurality of LED chips 21 that are disposed in an array on the circuit board 20 and that emit light to the display panel; and a lens 30 of a hemispherical shape that is disposed on the circuit board 20 and that covers each of the plurality of LED chips 21. A following relationship is established: R1/0.281≦̸L1, where L1 denotes an array pitch of LED chips 21 constituting the plurality of LED chips 21, and R1 denotes a radius of the lens 30. Accordingly, a light-emitting device achieving a high degree of light utilization efficiency and an excellent degree of color mixing, and a display device using the light-emitting device are provided.
